01:52 AM IchGucksLive: morning from germany
01:54 AM IchGucksLive: the logger is off
01:54 AM IchGucksLive: im off to garden
02:21 AM Deejay: moin
02:39 AM jesseg: So I've been getting my Tiawanese bp clone cleaned up and set up finally (the one I purchased 6 months ago...) and it comes with a 2 axis DRO and acme/trapezoidal feed screws..
02:39 AM jesseg: Anyway, it has no DRO on Z...
02:40 AM jesseg: I really don't want to install all new encoder scales just to upgrade to a whole new 3 or 4 axis...
02:42 AM jesseg: so what I'm thinking is if I can get a linear scale for the knee and one for quil then make my own LED readout that adds the two together...
02:43 AM archivist: easy enough
02:43 AM jesseg: so I guess my question is what kind of linear scale/sensor would be suitable for interfacing a DIY readout?
02:43 AM jesseg: I suppose some have complex proprietary protocols, and others probably have nice DIY friendly protocols
02:44 AM archivist: some have serial others AB like encoders
02:44 AM jesseg: gotcha
02:44 AM jesseg: Hmm, I wonder if AB type can be subtracted with xor gates LOL..
02:45 AM archivist: use maths in the micro
02:45 AM jesseg: lol yeah, that was just a funny thought I had :P
02:45 AM jesseg: Do you know off hand what brand or linear encoders would be DIY friendly?
02:46 AM jesseg: The encoders that it has on X and Y right now are the round steel tube that slides through the sensor
02:46 AM archivist: newey ?
02:46 AM jesseg: newall I think
02:47 AM archivist: yes thats it
02:47 AM jesseg: Sapphire it says :P
02:48 AM archivist: I have a brochure from some years ago Spherosyn, microsyn digital encoder
02:49 AM archivist: it is a series of ball bearings in the tube
02:50 AM jesseg: lol... like bug ones that fill the full diameter of the tube?
02:51 AM archivist: http://www.newall.co.uk/products/?name=Linear+Encoders&catid=67
02:51 AM jesseg: I guess that makes sense as long as the nylon plug at the end doesn't get lose and let the balls shift around
02:52 AM archivist: been around for some time now, probably easier to fit than glass scales
02:53 AM jesseg: yeah, lot tougher too :P
02:53 AM jesseg: I wonder how the absolute ones keep track of their position...
02:54 AM jesseg: Actually I noticed mine remembers its position when you turn it off, although I assumed it is just writing it to flash
02:54 AM archivist: have you moved it while off :)
02:55 AM jesseg: no but as I was thinking I should try that :P
02:55 AM jesseg: Wow there are a lot of relatively inexpensive no-name DRO's available from China
02:55 AM archivist: judging by the images they change some balls to sense absolute
02:56 AM jesseg: hmmmm...
02:56 AM archivist: http://www.newall.co.uk/upload/story/images/st_17_Image.jpg
02:56 AM jesseg: or maybe they put spacers between them, since changing a ball diameter would make it not stay centered
02:57 AM jesseg: oh gotcha, so they have a spacing pattern so it can always tell where it is
02:58 AM jesseg: Have you heard of any off the shelf DRO unit summing the quill and the knee?
02:59 AM archivist: http://www.ebay.co.uk/itm/Digital-Scale-100mm-4-Horizontal-Linear-LCD-Display-Inch-Metric-Caliper-Beam-/252759328037
02:59 AM archivist: there are the cheap capacitive some with serial out
03:00 AM archivist: http://www.ebay.co.uk/itm/0-300mm-0-01mm-Remote-Digital-Readout-linear-Scale-External-Display-/112170433911
03:00 AM jesseg: Yeah I saw a few like that.. All LCD.. I just can't tell you how much I live the big glowing LED readouts :P
03:00 AM jesseg: and that's when I had the thought that I should make my own, then I could make it sum the Z's
03:02 AM jesseg: oh but with serial out I could still do that, I see what you're sayingh
03:04 AM archivist: an arduino with 2 serial in and an LED display and not a lot of code
03:04 AM jesseg: haha that last one says "Doesn't post to united states!
03:04 AM archivist: the serial protocol that may be the hard bit
03:05 AM jesseg: yeah, but I think someone did figure out the protocol for the Chinese digital calipers and that first link looks to be just one of those with different mounting...
03:07 AM archivist: the one I have of this sort http://www.ebay.co.uk/itm/Digital-Scale-100mm-4-Horizontal-Linear-LCD-Display-Inch-Metric-Caliper-Beam-/252759328037
03:08 AM archivist: has got serial as well dunno where one can get leads
03:09 AM jesseg: How many times a second does it update the display roughly?
03:15 AM archivist: not enough
03:15 AM jesseg: lol yeah... that's the other thing I like about a real dro, you don't have to wait for it to update the display
03:15 AM jesseg: http://www.ebay.com/itm/2-Axis-Digital-Readout-Milling-Lathe-with-Precision-Linear-Scale-Grating-Machine/322481085375
03:15 AM jesseg: I suspect the cheap Chinese units are probably all AB style
03:16 AM jesseg: possibly differential
03:17 AM archivist: that seems display only but does not have the maths, hack the code?
03:17 AM jesseg: correct, also it does not include the sensors -- but it talks about the protocol
03:18 AM jesseg: and shows quad encoder signals in the pictures :P
03:18 AM archivist: yup normal glass scale AB
03:18 AM jesseg: which tells me that I could probably just get those cheapish AB sensors from China and they would *probably* be AB :P
03:20 AM archivist: the expensive AB from elsewhere are really imported from china with a mark up :)
03:21 AM jesseg: LOL yeah... and more quality control...
03:25 AM jesseg: What's the difference between the incremental and the absolute mode on a dro?
03:25 AM archivist: I have been surprised how accurate some of the cheap chinesium is
03:25 AM jesseg: It seems to keep two different counts going for each axis, and either can be independently cleared or preset..
03:26 AM jesseg: but otherwise they seem identical
03:26 AM archivist: incremental a zero anywhere on the scale, same as a caliper
03:27 AM archivist: absolute is the 0 it remembers when closed
03:27 AM archivist: absolute is harder to set
03:28 AM jesseg: oh so the difference is that absolute is harder to clear/reset?
03:28 AM archivist: yes
03:28 AM jesseg: I mean I understand the theoretical difference and operational difference of making an incremental vs absolute move
03:28 AM jesseg: but as far as I could tell, both inc and abs modes function just the same..
03:29 AM jesseg: a tap on the X0 or Y0 key zeroed either, and I could hit X nnn.nnn ENT to set either abs or inc
03:29 AM archivist: it is a long press on the mitutoyo to set abs
03:29 AM jesseg: so maybe on mine they are just the same but having a second one is still very handy because you can clear it at will
03:30 AM jesseg: What's the "1/2" button for?
03:31 AM jesseg: You know, what would be really handy is the ability to add or subtract a value from the inc reading..
03:32 AM jesseg: So if you were doing holes along a 0.5" spacing or 12mm or whatever, you could simply add each time to prevent slight drift in case the reading drifted a tiny bit during the last drill
03:33 AM archivist: 1/2 is probably diameter/radius on lathes
03:33 AM jesseg: oh gotcha
03:34 AM archivist: some readouts have hole spacing and and bolt circles
03:35 AM jesseg: lol yeah I guess that makes sense
03:35 AM jesseg: of course ultimately CNC is my goal so....
03:35 AM jesseg: but acme feed screws are kind of not super great for CNC
03:35 AM archivist: well go straight to linuxcnc but just as a readout
03:36 AM jesseg: Huh?
03:36 AM archivist: it has DRO built in
03:36 AM jesseg: oh gotcha
03:37 AM archivist: can do the maths for Z with two encoders
03:37 AM jesseg: yeah
03:37 AM jesseg: hmm, some of these claim "Z+Y sum (lathe machine)"
03:38 AM jesseg: I don't understand why you would want to sum to axes on a lathe
03:39 AM archivist: I suppose it could help you machine an angle
03:39 AM jesseg: oh I see
03:40 AM jesseg: so something like this might actually be able to sum my quill and knee out of the box...? http://www.ebay.com/itm/252675960621
03:44 AM archivist: well the cost compared to an arduino or linuxcnc
03:45 AM jesseg: Well, I have to buy the scales...
03:45 AM jesseg: and it's looking like a 2 axis kit is probably the cheapest way to get two scales..
03:45 AM archivist: that last one seems to include 2 scales
03:45 AM jesseg: yes
03:46 AM jesseg: so I figured if those two scales came with a summing readout at no extra cost, then it'd save me from having to code up something
03:47 AM jesseg: wow... these newall stuff is more expensive than the other Chinese stuff :P
03:48 AM XXCoder: newall? is that ripoff of newegg?
03:48 AM jesseg: LOL
03:48 AM jesseg: maybe there's a new humpty dumpty too
03:50 AM archivist: Newall is real british made still I think
03:50 AM jesseg: oh gotcha that explains the price
03:50 AM archivist: the company has shrunk a lot from its prime though
03:51 AM jesseg: hrm, yeah it looks like getting a kit with 2 scales and a readout from China is the cheapest way to get two scales :P
03:51 AM archivist: used to make the bees knees in jig borers
03:52 AM archivist: they also bought up other good companies like OMT, Optical Measuring Tools
04:02 AM jesseg: I may just take a gamble on one of these and see how they do.
04:03 AM jesseg: $200 should get me two scales and maybe even a readout I can use, but OK if not.
04:04 AM jesseg: The two Z axes are kind of out of the way and shouldn't be too hard to protect from chips/water
04:04 AM jesseg: well thanks very much for all the help archivist :D I really appreciate it!
04:04 AM jesseg: Good night :D
04:05 AM archivist: its morning! get up
04:05 AM jesseg: lol only 1:35AM here...
04:05 AM XXCoder: https://www.youtube.com/watch?v=l464ZF5jK3Y enjoy lol
04:05 AM jesseg: and I've been up for a long time already :D
04:05 AM jesseg: gn
04:18 AM miss0r: I was just made aware that you can get tungsten carbide wrist watches.... *Heavy breathing*
04:19 AM XXCoder: ?
04:19 AM miss0r: Do you guys know a good brand that makes these?
04:19 AM XXCoder: heh havent used watches for a whle but wouldnt that watch be heavy
04:20 AM miss0r: yes! and indestructable... ! a watch of the gods :D
04:20 AM XXCoder: very wear-resistant thats for sure
04:20 AM miss0r: unless ofcourse you drop it...
04:20 AM XXCoder: inocel watch, invented here
04:20 AM XXCoder: unless someone steals it :P
04:20 AM miss0r: :D
04:21 AM miss0r: I would like such a watch. I've been wearing the same seiko watch for the last 10 years. even thou its titanium, it pretty scratched by now.
04:22 AM miss0r: Also, I made an idiot mistake once with this watch - I had to change a lightbulb on my car, and managed to basically short the battery with the watch band.. It welded solid, and broke in two... I managed to mend it thou :D
04:22 AM XXCoder: ow
04:23 AM miss0r: but it hurt like hell. sounded like someone throwing some meat on a hot frying pan... and it hurt like hell. I still have a pretty cool scar thou
04:23 AM XXCoder: behold the insanity of sequel https://www.youtube.com/watch?v=tWXtBTTpcHk
04:24 AM miss0r: what the hell am I watching?
04:24 AM XXCoder: old game
04:24 AM XXCoder: the flashing is button you have to hit for it to be success
04:24 AM XXCoder: if sword flashes you gonna hit sword button for example
04:24 AM XXCoder: first one is quite a bit better
04:25 AM miss0r: shit
04:31 AM XXCoder: miss0r: the first one heh https://www.youtube.com/watch?v=C-dg4J9_nes
04:32 AM XXCoder: considerable simple but hard anyway
04:36 AM miss0r: I've never played that. I think its within the gap in time when I didn't play games
04:36 AM XXCoder: it's1980s game
04:36 AM XXCoder: the game was remade in 1080p later on but yeah
04:38 AM miss0r: I mosttly played 'supaplex' 'crystal cave' and 'the incredible machine'
04:39 AM XXCoder: loved last one!
04:39 AM XXCoder: I had 3rd one never had first 2
04:39 AM miss0r: work calls. I need to make a 3rd hand stand for a guy in ##electronics.
04:39 AM miss0r: I can't remember which one I had
04:39 AM miss0r: presumably the first
04:39 AM XXCoder: np later
04:40 AM XXCoder: https://www.youtube.com/watch?v=iE9GVn2mjs8 this game?
04:40 AM miss0r: yep
04:40 AM XXCoder: thanks
04:56 AM phipli: morning
04:57 AM XXCoder: hey
04:57 AM phipli: all well?
04:57 AM XXCoder: just found thayer's quest on yoiutube
04:57 AM XXCoder: then that game all possible deaths. that ones weird.
04:57 AM XXCoder: https://www.youtube.com/watch?v=YXwbqRbBOtg
04:59 AM phipli: if I was him, I'd have stayed home
04:59 AM XXCoder: LOL the one where 2 lizard beings hug him and he turns unto one of them
04:59 AM XXCoder: surpising many deaths is from monsters hugging him
05:01 AM phipli: lizards might be an upgrade
05:02 AM XXCoder: consdering how dangerous that world seems to be, yeah
05:06 AM phipli: https://en.wikipedia.org/wiki/Capacitance_Electronic_Disc
05:06 AM phipli: urgh - high density data on a disc played back with a stylus...
05:07 AM XXCoder: reminds me of that scheme (W once, read many) where stylus melts and indents spots on 1 inch by one inch. it was 1 gb for that space
05:07 AM XXCoder: huge density for back then
05:07 AM XXCoder: but it wasnt reliable enough
05:08 AM phipli: I bought an 8" floppy disk a while ago
05:08 AM phipli: to cause trouble with the IT deparment
05:08 AM phipli: department*
05:08 AM phipli: "I'm trying to move some files, but am having difficulty..."
05:10 AM XXCoder: reminds me of other failed media
05:10 AM XXCoder: its a crystal cube, 1 cm by 1 cm by 1 cm
05:10 AM XXCoder: 1 TB storage, 1 TBPS
05:11 AM XXCoder: essentally entire cube would be read in a second.
05:11 AM jthornton: morning
05:11 AM archivist: nearly coffee time
05:12 AM archivist: to B&Q or not that is the question
05:12 AM phipli: morning
05:12 AM phipli: archivist: what are you after?
05:12 AM archivist: some acrylic sheet
05:13 AM phipli: do they stock acrylic?
05:13 AM phipli: we have a wicks up the road and I don't think they do
05:13 AM phipli: worth knowing if B&Q do
05:13 AM archivist: need to make a water proof transparent meter compartment for the generator
05:14 AM archivist: B&Q and Wickes both used to have it
05:14 AM archivist: right opposite of each other in Burton
05:15 AM phipli: B&Q is a bit further away for me
05:15 AM phipli: Wicks and Screwfix are walking distance
05:15 AM archivist: I was a bit amused by a mechanical engineers answer to gearbox testing http://nervoussquirrel.com/gearbox1.html
05:17 AM archivist: encoder and watch frequency variation would be the electronic engineers version
05:18 AM phipli: yes, I think he'd use electronics these days
05:18 AM phipli: he used to be electronics averse
05:19 AM phipli: bad experiences with other people's pic code made him consider it unreliable when he was straight out of Uni
05:19 AM phipli: you've gone back a /long/ way with that page
05:19 AM phipli: I think that was his first job
05:19 AM phipli: when he worked for a remote control lighting firm
05:19 AM archivist: a local one?
05:20 AM phipli: In London
05:20 AM phipli: Wimbledon somewhere I think
05:20 AM archivist: ah I did some stuff for one in Melbourne
05:21 AM archivist: flashing bulbs for a shop display http://www.collection.archivist.info/archive/DJCPD/PD/2003/2003_07_19_a_flasher/P1010002.JPG
05:21 AM XXCoder: okay this is cool https://youtu.be/A4FjIOhKtgc
05:21 AM XXCoder: leds animation
05:22 AM phipli: How many cams you say? :)
05:23 AM phipli: archivist: your pcbs?
05:23 AM archivist: yes
05:24 AM phipli: XXCoder: amazing how fluid and analogue the result is considering the square frames
05:24 AM XXCoder: yeah
05:24 AM XXCoder: tilted
05:27 AM phipli: Right
05:27 AM phipli: how best to hijack the doorbell signal?
05:28 AM phipli: Relay coil in series with the signal?
05:28 AM XXCoder: rpi zero? that seem to be same level to 42 on answer to everything :P
05:28 AM phipli: pah
05:28 AM phipli: 3.3v
05:28 AM phipli: I'm guessing the doorbell is 12v
05:28 AM phipli: I was thinking relay + ESP8266
05:29 AM phipli: because I want a repeater in the shed
05:29 AM XXCoder: theres bunch of doorbell-light flash system you can hack if you prefer those
05:29 AM phipli: ... or I could use bell wire and hope the missus doesn't notice...
05:29 AM XXCoder: I bought one for $20 a while ago
05:30 AM phipli: I have a klaxon somewhere... perhaps I could use that at the far end :)
05:31 AM XXCoder: cat5 is designed to carry signal for long distance
05:31 AM XXCoder: can easily wire up if wiring is easy but wireless is not a option
05:32 AM phipli: both possible
05:32 AM phipli: I have CAT5 and I have radios
05:32 AM phipli: range on the ESPs seems to be good
05:32 AM phipli: I'll try them first
05:32 AM phipli: it isn't too far
05:32 AM XXCoder: heh or make it "internet enabled" lol
05:33 AM XXCoder: thats a bad fad so far
05:33 AM phipli: yay! security!
05:33 AM phipli: perhaps I could attach the front door lock to it...
05:33 AM XXCoder: theres wireless camera that has default unchangeable password of no password, has telnet to it too
05:33 AM phipli: there are many
05:34 AM XXCoder: so anyone could send in a program, crash and rebvoot camera. after that, own camera forever
05:34 AM archivist: extra door bell push direct to shed avoiding someone else :)
05:34 AM phipli: I bought one, found its fixed flashed telnet password on the internet and refused to install it
05:35 AM XXCoder: smart doorbell, detects if its a religious visit and disables button (it plays audio very close to them so they think it actually rang whole house)
05:35 AM phipli: a doorbell that locally plays a blasphemous phrase to drive them away?
05:36 AM XXCoder: nah it just rings constantly
05:36 AM XXCoder: even if not pressed agaibn
05:36 AM XXCoder: till they walk away
05:36 AM XXCoder: bonus: slowly increase volume (but never reaches point where people inside can hear it)
05:37 AM phipli: heh
05:37 AM phipli: I'd forgotten
05:37 AM phipli: my brother once connected an airraid siren to the doorbell to wind up his wife
05:37 AM phipli: she rang the bell... and it didn't stop for a good few seconds
05:39 AM archivist: phipli, do you have space in the shed http://www.ebay.co.uk/itm/272704785828?ul_noapp=true
05:40 AM XXCoder: phipli: bet it'd be annoying
05:40 AM XXCoder: has issues and $300 ouch
05:40 AM XXCoder: bet orginial is expensive
05:41 AM archivist: cheap, for the hardware, should be fixable
05:42 AM archivist: moving it not so simple
05:42 AM phipli: XXCoder: £300 = $380
05:43 AM XXCoder: oops missed euro mark
05:43 AM archivist: although looks lighter than the one I snaffled from Derby
05:43 AM phipli: Lancashire - tricky on the bike :)
05:43 AM phipli: XXCoder: Pounds Sterling!
05:44 AM archivist: real money
05:44 AM XXCoder: ah yes
05:44 AM phipli: although they've done something funny to our money
05:44 AM phipli: looks like plastic now
05:44 AM XXCoder: the euromark looks like 2 line middle curved E right?
05:44 AM phipli: well, the £5 notes are
05:44 AM phipli:
05:45 AM phipli: vs £
05:45 AM XXCoder: ya ok
05:45 AM phipli: :)
05:46 AM jthornton: in ardweenie what data type is this (2017, 12, 31, false)
05:46 AM phipli: your DateTime thing again?
05:46 AM archivist: looks like an attempt at a date, see the function it calls
05:47 AM jthornton: yea, just trying to replace the date info with current
05:48 AM archivist: that has ints so "get year from date"
05:48 AM archivist: etc
06:03 AM phipli: sigh. doorbel is 14v AC
06:03 AM phipli: *bell
06:04 AM phipli: and someone has used earth wire for both the live and neutral on the AC
06:04 AM phipli: people--
06:10 AM XXCoder: can ue resistors
06:17 AM phipli: rectify, smooth, regulate
06:17 AM phipli: faff
06:17 AM XXCoder: or ya know
06:17 AM XXCoder: replace whole system lol
06:17 AM XXCoder: nice 12v system :P
06:17 AM phipli: :)
06:17 AM phipli: would probably be less faff.
06:17 AM XXCoder: record the orginal sounds and play audio on presses lol
06:18 AM phipli: :)
06:25 AM XXCoder: dang
06:26 AM XXCoder: https://youtu.be/UzVhTJMMGLM
06:26 AM XXCoder: easy to make puzzle. good luck solving it thouggh
06:37 AM XXCoder: love how those old goverment videos are. https://www.youtube.com/watch?v=yYAw79386WI
06:39 AM phipli: Yeah - I was watching some of the american military explanations on transmissions the other day
06:40 AM XXCoder: this one is by chev I think but yeah same style
06:40 AM XXCoder: lol that test car
06:40 AM phipli: do they set the idle high on the bikes?
06:41 AM XXCoder: no idea
07:02 AM TurBoss: morning
07:03 AM TurBoss: well is mid day
07:07 AM phipli: morning somewhere
07:07 AM gregcnc: coffeetime
07:11 AM archivist: I didnt like the price of acrylic in B&Q or Wickes
08:13 AM phipli: archivist: not surprised
08:13 AM phipli: how much do you need?
08:15 AM archivist: for the 5 displays about 15" by 3 ish to cover the original meter holes and make water proof, seen a place on ebay that cuts to size for less
08:17 AM archivist: thinking of making a box over the displays and through the rusty panel to keep them dry
08:18 AM archivist: been living in the garden for a while http://www.collection.archivist.info/archive/DJCPD/PD/2005/2005_05_03_Generator/P4231086.JPG
08:21 AM Loetmichel: archivist: that looks like a genset that can supply a whole block of houses ;)
08:21 AM archivist: have not yet measured new display to see if they fit in the same distance
08:22 AM archivist: Loetmichel, 60A 3 phase 440 across 240 to neutral :)
08:22 AM Loetmichel: nice
08:23 AM Loetmichel: thats about double what our 4 appartment house here has as a main fuse
08:23 AM archivist: engine and alternator ok, bottom rotted out of the control panel and meters all dead
08:23 AM Loetmichel: (400V 32A 3p)
08:25 AM archivist: I wonder if the EU mains will drift back to the older voltages after brexit
08:39 AM archivist: oops new displays make it wider
08:39 AM phipli: archivist: did they ever change the voltages?
08:40 AM phipli: I thought they just changed what they were called
08:40 AM phipli: UK is still a mix of 240 and 250...
08:40 AM phipli: just /called/ 230
08:40 AM phipli: 230VAC +20/-10
08:40 AM phipli: or something like that
08:41 AM phipli: nice genset
08:41 AM phipli: looks a bit like an A-series with the shared port in the middle
08:46 AM * jthornton got one load of firewood split and stacked... I think one more load after breakfast then it will be too warm for that fun
08:48 AM archivist: phipli, it is a Morrison made in Loughborough with a 6 cyl Perkins 6354 engine
08:49 AM archivist: phipli, I though it was a rename with a drift to 230 eventually
08:56 AM phipli: I spent 6 weeks at perkins in Stafford
08:57 AM phipli: the old Dorman factory
08:57 AM phipli: they only do 4 litre / cyl engines there now I think
08:58 AM phipli: (unless it has changed since I was there)
08:58 AM phipli: They had some nice CNC kit :)
08:59 AM archivist: dunno what they do now that the evil americans bought Perkins
09:02 AM archivist: phipli, http://www.collection.archivist.info/searchv13.php?searchstr=dorman+pd
09:03 AM phipli: CAT were in charge when I was there
09:04 AM phipli: but the factory was reasonably independent in some ways
09:04 AM phipli: the usual HR + IT taken over
09:04 AM archivist: ah ok
09:04 AM phipli: Nice bunch in the design office, test labs and after sales support offices where I spent some time
09:04 AM phipli: really nice bunch
09:04 AM phipli: I'd consider going there for a job if I was looking
09:04 AM phipli: but...
09:05 AM phipli: all internet really closely monitored etc.
09:05 AM phipli: usual spying type weirdness from up on high
09:05 AM phipli: they piped their whole internet connection via america so they could spy on the staff
09:06 AM archivist: the retired from there have their own website, which I sent that image too, hence the description
09:07 AM archivist: last image shows the current state of the genset control panel http://www.collection.archivist.info/searchv13.php?searchstr=morrison+pd
09:07 AM archivist: new bottom welded in
09:10 AM phipli: lick of paint and you'll be sorted :)
09:10 AM phipli: heh
09:10 AM archivist: those meters are duff though
09:10 AM phipli: I heard an American getting on the Skylink bus try to say Loughborough the other week
09:12 AM archivist: he would have trouble with Groby or Fazeley
09:35 AM Loetmichel: soo, got my car radio/nav fixed and powered again (it fell out of the slot yesterday ;)... but the crack in the windshield starts to grow so big that it buggers me while driving... another €350 thru the drain this month... cant risk to drive with that or i will get fined. -> http://www.cyrom.org/palbum/main.php?g2_itemId=16670&g2_imageViewsIndex=1 http://www.cyrom.org/palbum/main.php?g2
09:35 AM Loetmichel: _itemId=16673&g2_imageViewsIndex=1
10:14 AM SpeedEvil: you can in principle DIY some repairs on windshield
10:16 AM Loetmichel: SpeedEvil: its glued in. i dont think i can do it "professionally" at home
10:16 AM SpeedEvil: stop-drilling the crack, and then injecting glue
10:16 AM SpeedEvil: I mean
10:16 AM Loetmichel: and the glie/toolkit for that windhield is 60 eur. add that to the 100++ eur windshield on ebay and the eur 350 replacement windhioeld with montage isnt that expensive after all
10:17 AM SpeedEvil: I was more meaning DIY.
10:17 AM Loetmichel: not in the core view area of the driver. would get you a ticket every time a cop sees you here in germany
10:17 AM SpeedEvil: Not actually really visible, done right
10:18 AM Loetmichel: its simply not allowed here
10:18 AM SpeedEvil: ah
10:18 AM Loetmichel: only on the corners
10:18 AM Loetmichel: not in the core view angle
10:19 AM Loetmichel: and to be honest: i think the cracks are there for a reason
10:20 AM Loetmichel: the previous owner of the car decided to put in a REALLY stiff coilover suspension (cheapest possible on the aftermarket)... i dont think i will replace the windshield before getting some (used) original shocks and springs.
10:21 AM Loetmichel: on the first long "autobahn" drive i did with that BMW i bite my lip because of the suspension...
10:21 AM Loetmichel: and german highways are SMOOOTh
10:21 AM SpeedEvil: :(
10:24 AM Loetmichel: funny thing is that that 1999 BMW 318i convertible goes close to 200kph SO easy that i didnt even notice until my satnav pinged me with "hey, here is 120kph spped limot, you're doing 192!"
10:24 AM Loetmichel: speed limit
10:35 AM phipli: They don't let us do more than 112km/h
10:40 AM Loetmichel: the stretch before that "ping" was no limit.
10:40 AM Loetmichel: so i "swam in the traffic" with the other cars.
10:41 AM Loetmichel: didnt even notice how fast i was until the satnav warned
10:41 AM Loetmichel: it does go 210kph according to the paperwork
10:56 AM pink_vampire: hi
12:59 PM JT-Shop: the BlueWing will do 220 kph and has been up to 200 kph with me on it... 200 is plenty fast for a bike
01:00 PM archivist: somewhat above your speed limits :)
01:02 PM * roycroft is a putt-putt driver, and likes to enjoy the scenery as he meanders about
01:02 PM roycroft: but i am respectful enough to stay in the slow lane except when overtaking!
01:03 PM roycroft: i am also allergic to freeways, and drive on the back roads almost exclusively
01:04 PM archivist: are you lot still stuck at 65 max
01:04 PM roycroft: we've increased the speed limit in rural oregon to 70mph in some places
01:04 PM pcpipo: Hi
01:04 PM roycroft: but most of the state is 65mph max on freeways, and 55mph max on not freeways
01:05 PM LeelooMinai: "because some cyclist started to exceed it at times"
01:05 PM roycroft: california and washington have a limit of 70mph on freeways in most places
01:06 PM roycroft: i was driving through montana after the federal limit was lifted
01:06 PM roycroft: the posted limit there was "85mph nights"
01:07 PM roycroft: they've dialed that back though
01:07 PM LeelooMinai: Pretty cool: https://www.youtube.com/watch?v=T5DFD--Vkv8
01:08 PM LeelooMinai: How to make steel look like playdough:)
01:09 PM roycroft: up until the oil embargo in '74, when the national speed limit was imposed, oregon and montana had the basic law, which stated that the maximum speed is what is "reasonable and prudent"
01:10 PM roycroft: we only recently repealed the basic law, and as such, our posted limits until very recently said "speed 65", instead of "speed limit 65", as in the rest of the country
01:10 PM roycroft: the posted limit was essentially a recommendation of what is reasonable and prudent
01:11 PM roycroft: a recommendation that law enforcement followed
01:14 PM gregcnc: 85MPH is normal around chicago even when posted 55
01:15 PM JT-Shop: 75 in western states even on 2 lane roads
01:16 PM roycroft: things sure have changed since i lived in chicago
01:16 PM gregcnc: I have to move out of IL before it declares bankruptcy
01:16 PM roycroft: people wished they could drive 55mph when i lived there, which was the posted limit
01:17 PM roycroft: but 25-35mph was more like the actual cruising speed most of the time
01:17 PM roycroft: when i was young, the dan ryan expressway had no express lanes yet
01:17 PM roycroft: it was basically just 10 lanes of traffic
01:17 PM roycroft: all weaving back and forth, and causing a mess
01:18 PM * roycroft rode the train a lot
01:18 PM roycroft: it was faster than driving into downtown
01:19 PM gregcnc: i don't go downtown
01:19 PM roycroft: the last time i was downtown it was a ghost of what it used to be, and that's been a good 20 years
01:20 PM roycroft: i was rather shocked to find out that people tried to get away from downtown before dark
01:21 PM roycroft: but places change, and if you're away from them for a long time the changes can be really apparent when you go back
01:23 PM JT-Shop: we went to a Diners Driveins and Dives restaurant in Austin and we did not stop there must have been several hundred homeless people on the next block and no parking
01:43 PM Phiplii: JT-Shop : Got the motor controlled remotely and running in both directions.
01:44 PM Phiplii: just need the scheduler in the code and the limit switches putting in.
01:44 PM Phiplii: and for the rest of the bits to arrive for the mechanical part
01:50 PM MrHindsight: what source of time does Tom use for his logger? http://tom-itx.no-ip.biz:81/~tom-itx/irc/logs/%23linuxcnc/2017-06-10.html
01:50 PM MrHindsight: looks about 30 minutes in the future
01:51 PM MrHindsight: if you could see 30 minutes into the future what would you do?
01:51 PM malcom2073: Win the lottery and disappear
01:52 PM Crom: Tom's clock is off
01:52 PM malcom2073: Someone knocked his clock off
01:52 PM MrHindsight: malcom2073: vanish from the universe?
01:53 PM malcom2073: MrHindsight: Nah just from people
01:53 PM MrHindsight: invisible?
01:53 PM MrHindsight: look like a homeless person
02:06 PM JT-Shop: phipli: nice
02:06 PM JT-Shop: you using a RTC?
02:28 PM Crom: Roger Webb in 176 High Quality, Best quality steel.. heheh
02:29 PM Crom: Presision made!
02:29 PM Crom: pacifictooling.com still isn't up
02:55 PM * LeelooMinai inspects her $199 CAD MIG welder
02:56 PM Loetmichel: LeelooMinai: ah, couldnt help it and ordered one?
02:56 PM Loetmichel: ;)
02:56 PM Loetmichel: gas or gasless?
02:57 PM LeelooMinai: Right, I could not resist as it was on sale. It's gas-capable, but without the gas bottle, etc. - for now I got flux wire to see how it goes. I guess in theory I could weld aluminum with it with gas, but, baby steps:)
02:58 PM LeelooMinai: Heavier than I thought though and bigger - looked smaller on pictures.
02:58 PM Loetmichel: only if it has AC
02:58 PM LeelooMinai: Right, I know it has polarity change for gas/flux, two-position voltage control, wire feed control and I think one more, but not sure - need to reed if it's AC.
02:59 PM Loetmichel: you can also do aluminium on DC-reverse polarity
02:59 PM Loetmichel: never tried tho with a MIG
02:59 PM Loetmichel: did so with a TIG
02:59 PM Loetmichel: where it works but eats tungsten rods for breakfast
03:00 PM LeelooMinai: A, ok, so, probably does not have AC, but they mention to use argon only for aluminum somewhere there.
03:01 PM LeelooMinai: I need to read a bit more about the torch - I wanted to try the wire feed, but was not sure what is under voltage there and what not.
03:02 PM LeelooMinai: Like, is the current going through wire or through that collar on the end of the torch, etc. - no idea.
03:02 PM Loetmichel: the current is going thru the copper nozzle the wire is fed thru
03:02 PM Loetmichel: thats the reason the copper nozzle has to FIT the wire
03:03 PM Loetmichel: or it'll arc inside the nozzle and weld the wire into it
03:03 PM LeelooMinai: A, right, ok, so the arc forms between wire and the workpiece and you are supposed not to touch the worpiece with that copper collar?
03:03 PM Loetmichel: yes
03:04 PM Loetmichel: you can touch the workpice with the collar
03:04 PM Loetmichel: it should be insulated
03:04 PM LeelooMinai: Hmm, that may be tricky I guess - could not they protect the edge of it with something? Ceramic or teflon?
03:04 PM Loetmichel: but its better to get used to holding the correct distance
03:04 PM Loetmichel: not for insulating problems but for not getting to close to the workpiece with your nozzle
03:05 PM LeelooMinai: Er, right, I don't get that part - so is the collar hot or insulated...
03:05 PM Loetmichel: also the gas flow will be odd if one side of the collar touches the workpiece
03:05 PM Loetmichel: the COLLAR is insulated
03:05 PM Loetmichel: the nozzle in the middle isnt
03:05 PM LeelooMinai: I mean I saw some insulation cylinder in there, but then the collar is just screwd onto the end of the gun...
03:05 PM Loetmichel: you can pull the collar of to clean it then you'll see the insulation gap
03:06 PM Loetmichel: its not screwed usually
03:06 PM Loetmichel: just jheld there with a spiral spring
03:06 PM LeelooMinai: So what's the point of the colar... I mean why is it copper if it's insulated from everything?
03:06 PM Loetmichel: the collar is the gas nozzle
03:06 PM Loetmichel: it could have been made of any metal or ceramic
03:07 PM Loetmichel: it usually is steel, not copper
03:07 PM Loetmichel: or chromed brass
03:07 PM Loetmichel: in the most gas nozzles i have seen
03:07 PM LeelooMinai: A, maybe I did not look close enough - I thought that the collar is shorted to the gun when screwed on.
03:08 PM LeelooMinai: I wonder why mine is copper - or at least I think it is. Certainly not steel.
03:10 PM Loetmichel: try a file on one edge
03:10 PM Loetmichel: it may be copper clad steel
03:10 PM Loetmichel: usually done to prevent the steel sparks from sticking to the gas nozzle
03:10 PM LeelooMinai: Also, on the picture they have it like this: http://i.imgur.com/DgxGjwo.png
03:11 PM Loetmichel: yeah, if you use flux wire and no gas you dont need the gas nozzle ;)
03:11 PM LeelooMinai: Weird - is this some kind of "gas-less" configuration and I should use the collar only for gas and not flux?
03:11 PM LeelooMinai: A, ok
03:11 PM Loetmichel: exactly
03:11 PM Loetmichel: you can leave the collar on
03:11 PM Loetmichel: but its not used
03:12 PM LeelooMinai: I guess it should be nicer without as the collar can be in the way.
03:12 PM Loetmichel: its only pourpose is to direct thegas flow to the weld puddle
03:12 PM Loetmichel: it can
03:12 PM LeelooMinai: You use gas, like CO2 at least?
03:13 PM LeelooMinai: I mean you at work.
03:13 PM Loetmichel: i use pure (beer) C02 for mild steel, corgon for higher grade steel and pure argon for aluminium and stainless
03:14 PM Loetmichel: not at work tho, because we have no welding equipment at work if i dont bring my own stuff there
03:14 PM Loetmichel: (which i do occasionally)
03:14 PM LeelooMinai: Is the gas part expensive? I mean, can one have asome baby-co2 tank with regulator and that's all?
03:15 PM Loetmichel: if you are only doing mild steel you can get by with tanks intendeed top pressurize beer coolers
03:15 PM Loetmichel: they are pretty cheap here
03:15 PM LeelooMinai: O, I have an idea - I have furnace gas in the basement - can re-route the pipe to MIG.
03:15 PM Loetmichel: for any higher grade steel you should use at elast Corgon, wich is a mix
03:15 PM LeelooMinai: j/k:p
03:15 PM Loetmichel: pure argon is pretty expensive
03:16 PM Loetmichel: furnace gas?
03:16 PM LeelooMinai: Well, yes, we have home heating by gas furnace.
03:16 PM Loetmichel: thats no c02 in there
03:16 PM LeelooMinai: Most people here do I think.
03:16 PM Loetmichel: not a good idea ;)
03:16 PM LeelooMinai: Loetmichel: I know, was kidding:)
03:17 PM Loetmichel: ah
03:17 PM Loetmichel: sorry
03:17 PM LeelooMinai: Hmm, co2 for beer coolers - had no idea that's a thing.
03:17 PM LeelooMinai: Probably because I don't drink beer.
03:17 PM Loetmichel: not all people know. for some "gas" is "gas" regarless if its co2 or butane/propane or argon or whatever
03:18 PM LeelooMinai: Well, I think even totally cluless person would notice that the gas for heating kind of burns:)
03:18 PM Loetmichel: LeelooMinai: all "pub" systems that have a barrel in the cellar and the tap on the bar top use c02 for pressurizing the barrel
03:19 PM Loetmichel: these tanks can be bought and refilled at the same places that sell the barrels. and pretty cheap too
03:19 PM LeelooMinai: So it's just to "pump" the beer up?
03:19 PM Loetmichel: kinda
03:19 PM Loetmichel: and dont let the contents of the barrel go "flat"
03:19 PM LeelooMinai: But don't you have then beer with co2 bubbles like soda or something?
03:19 PM Loetmichel: thats the idea
03:19 PM Loetmichel: all beer HAS c02 bubbles in it
03:20 PM Loetmichel: thats where the foam on top comes from ;)
03:20 PM LeelooMinai: A, ok, what do I know:)
03:20 PM Loetmichel: i successfullly weldeded with a "sodastream" tank btw
03:20 PM Loetmichel: if thats something thats aviable in your country
03:20 PM LeelooMinai: From stainless?
03:21 PM Loetmichel: hmm?
03:21 PM LeelooMinai: I think roycroft used those in some strange brewing system.
03:21 PM LeelooMinai: Loetmichel: I mean what was the tank made of?
03:21 PM Loetmichel: sodastream is a system to carbonize your own tap water
03:21 PM Loetmichel: the sodastream tank?
03:21 PM LeelooMinai: Right
03:21 PM Loetmichel: steel or aluminium, depending on age
03:22 PM Loetmichel: the older machines use steel tanks, the newer aluminium ones
03:22 PM LeelooMinai: I guess people in Germany are more sophisticated in terms of beer than in other places.
03:23 PM LeelooMinai: Like in Russia/Poland you would get more specialists in making vodka at home:)
03:23 PM Loetmichel: we also LOVE sparkling water here
03:23 PM Loetmichel: :-)
03:23 PM Loetmichel: s/carbonize/carbonate
03:24 PM Loetmichel: my english seems to be a bit rusty ;)
03:24 PM LeelooMinai: I remember my dad had some contraption for making vodka - had a lot of copper pipes and at the end it dripped pure "product" - at this time it was not even legal so everyonw was doing it secretly.
03:24 PM Loetmichel: it still isnt legal
03:24 PM LeelooMinai: Hmm, people cannot make alcohol at home to this day?
03:24 PM Loetmichel: in germany you can do it but only with a 1 liter volume for the distillery tank
03:25 PM Loetmichel: so about a shotglass full of vodka a time
03:25 PM LeelooMinai: Right, well, but who will check how much you drunk:p
03:25 PM Loetmichel: I think thats an EU rule so it should be the same in poland
03:25 PM Loetmichel: LeelooMinai: its about the size of the distillery
03:26 PM gregcnc: https://www.discovery.com/tv-shows/moonshiners/
03:26 PM Loetmichel: not how often you use it
03:26 PM LeelooMinai: What is "moonshine" mashine?
03:26 PM LeelooMinai: "sounds weird"
03:27 PM Loetmichel: its called "moonshine" because it was/is forbidden in the US also. so they made it at night
03:27 PM LeelooMinai: Is it named that because you use it hiding in the woods at moon time? :)
03:27 PM Loetmichel: exactly
03:28 PM LeelooMinai: A, ok, I guess people all over the world tried to make themsleves poisoned by alcohol by any means necessary, legal or not.
03:28 PM gregcnc: alcohol - the cause of and solution to all problems
03:29 PM Loetmichel: gregcnc: especially the solution ;)
03:29 PM LeelooMinai: If only it was not killing brain cells:)
03:29 PM Loetmichel: <- plops another "keiler"
03:29 PM gregcnc: some of us have a few extra so it's ok
03:31 PM LeelooMinai: gregcnc: Sometimes extras can be a burden, indeed - like a car with 5 wheels:)
03:31 PM Loetmichel: LeelooMinai: sometimes i wonder how germans got the "great engineers and thinkers" fame... while being the second most beer consuming country there is... after the polish ;)
03:32 PM LeelooMinai: Loetmichel: Well, maybe the difference is that Polish would drink and work, and German drink, and work the next day - not sure:p
03:34 PM Loetmichel: dont get me wrong. i have great respect for polish workers... seeing them repair a car that was basically looking like out of a trash compactor...
03:34 PM Loetmichel: :-)
03:34 PM LeelooMinai: I think Japanese are considered good engineers too - they are a bit OCD though.
03:35 PM Loetmichel: on the other hand: i can weld a perfectly straight weld bead when i am so drunk that i cant walk in a straight line...
03:35 PM LeelooMinai: Loetmichel: Well, Polish are great MacGyvvers - mostly because while under Russia grip, one had to make everything from "nothing".
03:36 PM Loetmichel: yeah, i got that a long time ago that polish dont really like the russians
03:38 PM LeelooMinai: Right, no, not really - they never did anything good for past century at least.
03:39 PM Loetmichel: like in that joke about the fairy that grants a polish man 3 whishes. and he says "make it so that the chinese invade poland and then pull back home." "hmm, strange, but ok. Your second whish?" "do it again!" "hmmm, i can do that. but why? and your third whish?" "do it another time!" "ok, i will, but only if you tell me why!"
03:39 PM Loetmichel: "easy. if the chinese were 3 times in poland they had to come thru russia 6 times!"
03:40 PM LeelooMinai: Loetmichel: Even when they pushed out your German friends, they waited a long time by Warsaw when it was trying to rise by itself instead of helping. And then of course controlled Poland with their communist madness for decades. Fail:)
03:41 PM Loetmichel: LeelooMinai: s/friends/ancestors
03:41 PM LeelooMinai: Right, potato/tomato:p
03:44 PM Loetmichel: and i tink you will not find that many people in poland that still hold a grudge againss germans. (a few elderly maybe). But a lot of people that absolutely resent any russian. To the point thats its WAY more likely to get an answer in poland with german questions than with russian ones.
03:45 PM LeelooMinai: Loetmichel: But Russians gave good example that sometimes great engineering may be detrimental - by zerging with low-tech T-34s the expensive German tanks that were difficult to repair.
03:45 PM Loetmichel: more likely not aviable in the numbers needed
03:45 PM LeelooMinai: Well, if they are overenginnered, then yes, you cannot just build them in numbers like they could.
03:46 PM Loetmichel: iirc the german tanks were 100:1 overpowered by the end of the war
03:46 PM Loetmichel: in numbers
03:46 PM LeelooMinai: That's what I meant by "zerging" - it's where you build a lot of cheap weaponry and overwhelm the more sophisticated opponent.
03:47 PM LeelooMinai: Also, I think in harsh conditions, like winter there, etc. Simple = bonus.
03:47 PM Loetmichel: yeah, it obviously worked. the "mass produce" option wasnt open to a country that had less than 10% of the russian ressources tho
03:48 PM Loetmichel: it also was a good thing they won. i dont think i would like to live in a world where the nazis won.
03:48 PM LeelooMinai: Loetmichel: Should watch the Man in High Castle TV series:)
03:49 PM LeelooMinai: The Germany and Japan won there and divided US in two halves.
04:18 PM Deejay: gn8
04:50 PM Phiplii: JT-Shop : might just fetch the time off tinterweb
04:51 PM Loetmichel: LeelooMinai: did so. not my kind of stuff.
04:51 PM Loetmichel: (only 5 episodes of the forst season though)
04:52 PM Loetmichel: s/so/so just now
04:54 PM XXCoder: LeelooMinai: I read the orginial book - man in high castle. interesting
04:54 PM XXCoder: though tv series so far seem to be completely different story just similiar in background.
04:56 PM LeelooMinai: I thought it was decently made - attention to details and nothing really too retarded:)
04:57 PM LeelooMinai: Hmm, if I have galvanized sheet of metal, should I "strip" the galvanized surface with some sandpaper or something more brutal?
04:58 PM LeelooMinai: Befor welding that is.
05:00 PM LeelooMinai: In the brutal category I have angle grinder + one of those flap disks - that is pieces of sandpaper at an angle on top each other like shingles on a roof.
05:00 PM XXCoder: LeelooMinai: wear a good mask. avoid zinc fever
05:00 PM LeelooMinai: What "zinc fever":(
05:00 PM XXCoder: galivized surfaces has zinc in it
05:01 PM XXCoder: if you intale enough zinc powder you will get sick while body cleans it up
05:01 PM LeelooMinai: Wonderful
05:01 PM XXCoder: https://en.wikipedia.org/wiki/Metal_fume_fever
05:04 PM LeelooMinai: I have a welding dust like mask with a valve and also chemical mask for paints.
05:04 PM XXCoder: yeah that should limit exposure enough
05:04 PM LeelooMinai: Maybe the welding one works...
05:04 PM XXCoder: its not deadly in most cases anyway just want to avoid issues
05:04 PM Loetmichel: also called "welders fever" for a reason
05:05 PM Loetmichel: chear all zinc from the steel AT LEAST 1" from the weld
05:05 PM Loetmichel: beter 2"
05:05 PM Loetmichel: better
05:05 PM Loetmichel: clear
05:05 PM LeelooMinai: I know there's "mad as a hatman" saying, hope there's no "batshit crazy like a welder one"
05:05 PM XXCoder: nah its like flu
05:06 PM XXCoder: it fades in a day or 2
05:06 PM Loetmichel: like a REALLY bad flu
05:06 PM Loetmichel: i know, i have been there
05:06 PM Loetmichel: NOT pleasant
05:06 PM XXCoder: I havent thankfully
05:06 PM LeelooMinai: Loetmichel: You did not wear a mask?
05:06 PM Loetmichel: i did not bother to clear the zinc from some galvanized sheet metal before welding
05:07 PM Loetmichel: the welding arc DOES a pretty good job of evaporating it though
05:07 PM XXCoder: ouch. thats worse than intaling powder from grinding
05:07 PM XXCoder: far more fine
05:07 PM XXCoder: no wonder you got seriously sick
05:07 PM Loetmichel: its metal vapor, not dust
05:07 PM LeelooMinai: Loetmichel: But you had any kind of mask or none?
05:07 PM Loetmichel: none
05:07 PM XXCoder: I didnt say it was dust, just far more fine
05:08 PM Loetmichel: you could say i learned "the hard way" about welders fever.
05:08 PM XXCoder: indeed
05:08 PM LeelooMinai: Right, I need to figure out how to weld outside. I have a small patch in the backyard with concrete tiles there, but I need to do something so the neighbour or his dog do not have arc in direct sight.
05:09 PM Loetmichel: why?
05:09 PM XXCoder: maybe a strong ducted fan that has inlet near weld area
05:09 PM LeelooMinai: Loetmichel: Well, because I don't want someone complaining that I burned their corneas or something:)
05:09 PM Loetmichel: the dog will not look at it after the first time. and if the neighbor is at least somewhat intelligent he wont either ;)
05:09 PM LeelooMinai: Ok, but you know - chidlren, etc. - cannot risk it.
05:09 PM Loetmichel: its not THAT bad if they dont stand next to you
05:10 PM LeelooMinai: I thought of making some tiny 3-side shield from something.
05:10 PM XXCoder: lee you can make portable wall with pvc pipes, rubber tiedowns and tarp
05:10 PM Loetmichel: usually you get "only" the feeling of sandpaper under your eyelids for a few days if you omit the shield while welding yourself... dont ask how i know ;)
05:10 PM XXCoder: my old job they made chip sheild that way.
05:10 PM LeelooMinai: XXCoder: Well, tarp could kind of burn...
05:10 PM XXCoder: not if its more than few feet away
05:11 PM Loetmichel: LeelooMinai: wet it beforehand
05:11 PM XXCoder: its so cheap you can make pretty big ones. and yeah wet
05:11 PM Loetmichel: it wont burn then and repel any glowing particles
05:11 PM LeelooMinai: Loetmichel: lol... how could you not notice that there's no shield?
05:11 PM Loetmichel: i didnt say i didnt know
05:12 PM Loetmichel: i said "omit" ;)
05:12 PM Loetmichel: i had no room for it
05:12 PM Loetmichel: under a car
05:12 PM XXCoder: no lift?
05:12 PM LeelooMinai: Loetmichel: I thought Germans never go "fill retard" :)
05:12 PM LeelooMinai: full*
05:12 PM Loetmichel: so i kinda welded "blind" by postioning the mig nozlle, then closing the eyes and do the bead
05:12 PM Loetmichel: but sometimes you close the eyes to late ;)
05:12 PM LeelooMinai: Right, like eyelids will help...
05:13 PM Loetmichel: eyelids DO help. IF you close them
05:13 PM Loetmichel: the other thing is tho: i got the sunburn of my life from it ;)
05:13 PM LeelooMinai: Well, yes, but that's not really sufficient I think.
05:13 PM Loetmichel: being only a foot away from the arc with my face ;)
05:13 PM XXCoder: new kickstarter, arc tan booth
05:13 PM Loetmichel: hihi
05:14 PM LeelooMinai: Loetmichel: I am disappointed - I would expect a Russian or Indian doing that:p
05:14 PM XXCoder: it just has 3 arcs just stand and turn around slowly for nice tan lol (wear eye protection)
05:14 PM Loetmichel: <- is sometimes a bit careless if its about my own health
05:14 PM XXCoder: LeelooMinai: theres rednecks everywhere ;)
05:14 PM Loetmichel: XXCoder: its also a speed tan
05:15 PM Loetmichel: took less than 5 minutes to get a nice second degree sunburn :-)
05:15 PM LeelooMinai: I am the opposite - too careful about safety:)
05:15 PM XXCoder: im halfway in middle, unless its risks for eyes, then im careful as fuck
05:16 PM Loetmichel: LeelooMinai: http://www.cyrom.org/palbum/main.php?g2_itemId=12244&g2_imageViewsIndex=1 <- if you know what i mean about "careless"
05:16 PM LeelooMinai: XXCoder: Good idea. I mean you can still read IRC without hands, but you can neither read or write with no eyes.
05:16 PM LeelooMinai: O, wait...
05:16 PM XXCoder: I'm only one at work that wears goggles over regular glasses. others wear just goggle or glasses
05:16 PM Loetmichel: this pic was made by my apprentice. "to hang on the school blackboard, "how to NOT do it!"
05:16 PM XXCoder: lee actually still possible, I knew few deaf-blind people
05:16 PM LeelooMinai: Loetmichel: ...
05:17 PM LeelooMinai: XXCoder: Right, that's what I realized - some blind people are on irx. One girl in ##electronics.
05:17 PM Loetmichel: ... he did help me afterwards to extinguish the burning trashcan under the table i had trwon in the alcohol soaked wipes seconds before ;)
05:17 PM XXCoder: crazy
05:17 PM XXCoder: is it you, lucas?
05:17 PM LeelooMinai: Loetmichel: But you know that glasses are good, but they will not protect you from things that bounc around? :)
05:18 PM Loetmichel: i do
05:18 PM Loetmichel: thats why i squint there ;)
05:18 PM Loetmichel: XXCoder: lucas who?
05:18 PM LeelooMinai: Right, what can go wrong:p
05:18 PM XXCoder: star wars author and director heh
05:18 PM Loetmichel: ah, george lucas?
05:19 PM Tom_L: Loetmichel, i don't see any open fuel containers...
05:19 PM LeelooMinai: Loetmichel: That's insane - you don't even heave ear protection there...
05:19 PM Loetmichel: no, sorry, he is a BIT older than me
05:19 PM Tom_L: perfectly safe..
05:19 PM XXCoder: http://pop.h-cdn.co/assets/16/23/980x490/landscape-1465750530-glasses.jpg
05:19 PM Loetmichel: Tom_L: the white bottle with the red cap si actually 99% ethanol
05:19 PM LeelooMinai: I find I cannot keep focused without ear protection with loud machinery and it's dangerous.
05:19 PM Tom_L: meh, the lid's on it
05:20 PM Loetmichel: XXCoder: that what i call a "close call"
05:20 PM LeelooMinai: Right, probably was too much work to take the shield off that grinder:p
05:20 PM XXCoder: very safe https://imgur.com/Zte7Shn
05:20 PM Loetmichel: LeelooMinai: now that you say it... never noticed that was still on ;)
05:21 PM XXCoder: loet theres bunch of hurt people on face with grinder. ouch. all harbour freight
05:21 PM XXCoder: im definitely not buying HF grinder, in least not grinder wheel
05:21 PM Loetmichel: XXCoder: i had a few 230mm discs explode on me.
05:21 PM Loetmichel: none in the face so far
05:21 PM LeelooMinai: Actually I just bought a new grinder just because the other one had idiotic on/off switch on the back, so to turn it off you needed to use one hand instead of holding stuff.
05:21 PM LeelooMinai: Don't know who thought it's a good idea...
05:22 PM XXCoder: Loetmichel: probably because youre smart enough to never have spin plane cross your body and face
05:22 PM Loetmichel: not across the face
05:22 PM Loetmichel: the body had gotten its fair share of bruises from grinder discs
05:22 PM LeelooMinai: Those grinder disks always worry me - did not have one expolde on me yet, but the whole idea is scary.
05:23 PM Loetmichel: i can tell you that a 230mm cutting wheel expldong and half of it hitting yoru solarprexus DOES get the wind out for a while
05:24 PM XXCoder: heh I still wonder how this happened, a chip somehow bypassed my safety glasses, bounced off my face, and hit my glasses by behind
05:24 PM Loetmichel: i sometimes say that if you work with less safety equipment you automatically are more carefull to avoid the WORST consequences.
05:24 PM XXCoder: the dot it made i bit annoying
05:24 PM Loetmichel: as "never be in the plane with your HEAD"
05:24 PM LeelooMinai: XXCoder: Did you check if there's a through hole through your head maybe? :)
05:24 PM XXCoder: lol
05:24 PM Loetmichel: XXCoder: like this? http://www.cyrom.org/palbum/main.php?g2_itemId=10351&g2_imageViewsIndex=1
05:25 PM Loetmichel: and i WAS wearing eye protection when that particle from a dremel cutting disc found a way...
05:25 PM XXCoder: thankfully in my case chip missed my eye, as it hit hard enough to bounce and mark glasses
05:25 PM XXCoder: I need new glasses.
05:25 PM LeelooMinai: I guess it was not the proper one - I use google-like - no way anything goes through those.
05:25 PM LeelooMinai: goggle
05:26 PM Loetmichel: it was a proper one
05:26 PM Loetmichel: somehow the particle found its way thru the "air vents" on the side pieces of the safety googles
05:26 PM XXCoder: wow
05:27 PM Loetmichel: and it was still hot enough to melt itself into the eye
05:27 PM XXCoder: LOL https://www.kickstarter.com/projects/373670816/r-pur-anti-pollution-mask-made-in-france?ref=HappeningNewsletterJun1017
05:27 PM XXCoder: coming from recent discussion
05:27 PM LeelooMinai: What... That's normal in some Asian cities from what I know.
05:28 PM XXCoder: it apparently can filter nano paracles
05:28 PM XXCoder: so little bit more fancy than normal masks
05:28 PM LeelooMinai: Especially if you are on bike/bicycle, it's not a bad idea...
05:28 PM Loetmichel: asians usually have only those "clinical" masks
05:28 PM Loetmichel: this kickstarter thing looks like it has activated carbobn in it
05:28 PM XXCoder: yeah good enough to block germs viruses
05:28 PM LeelooMinai: Right, well, yes, but that's probably due to costs.
05:29 PM LeelooMinai: I had a mask like that, but it was not for pollution, but winter cycling:)
05:29 PM XXCoder: pretty cool but dont think I need one
05:30 PM LeelooMinai: Plus tires with carbide spikes from Nokkia or whatever they were and you roll... well, people still look at you like you are mentally challenged, but who cares:)
05:31 PM Loetmichel: LeelooMinai: i think that would clash with my usual "bike" outfit...
05:31 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=15295&g2_imageViewsIndex=1
05:32 PM LeelooMinai: You look like a cop in UK or something like that:p
05:32 PM Loetmichel: (no, that is NOT a harley. its a 50cc "moped"
05:33 PM LeelooMinai: Well, seems like something between a scooter and a a bike:)
05:33 PM Loetmichel: why? because of the beer belly? :-)
05:33 PM LeelooMinai: I think the helmet + whatever you have there on the side - looks like cop's radio or whatever.
05:34 PM Loetmichel: leatherman tool and Samsung note 3 ;)
05:34 PM Loetmichel: and the hemlet is because i hate the "enclosed" feeling in a full (integral) helmet
05:35 PM LeelooMinai: I once found that doctors in ERs call motocycle riders "donors":)
05:35 PM Loetmichel: the sun visor is acutally nice, didnt knew it had that until i examined the helmet a bit closer after purchase
05:35 PM Loetmichel: LeelooMinai: and for good reason
05:36 PM Loetmichel: motorcycle accidents often end with a smashed head, so the the rest of the body is "still good"
05:36 PM LeelooMinai: Sounds great...
05:37 PM LeelooMinai: I guess no one yet needs brain transplant... well, or can get one.
05:37 PM XXCoder: brain is container of who you are
05:37 PM Loetmichel: it has actually been done to apes as far as i know
05:37 PM Loetmichel: but wouldnt that be more like a "body transplant" to the brain?
05:37 PM LeelooMinai: Semantics:)
05:38 PM XXCoder: indeed lol
05:38 PM LeelooMinai: I guess maybe eyes could be used for something? Like transplanting cornea... Not sure if they can do that.
05:39 PM Loetmichel: its regularily done
05:39 PM Loetmichel: cornea transplants i mean
05:39 PM LeelooMinai: "O, found the head, cool - did Bob forgot thethe eye extractor again?"
05:39 PM Loetmichel: i dont think it works that way
05:40 PM LeelooMinai: Right, ok, so head is worth saving too:)
05:40 PM Loetmichel: anyways: i am ok with a little risk in my life. and you CAN drive a bike reasonably safe
05:40 PM Loetmichel: even the big ones
05:41 PM LeelooMinai: THough I would think that by now the better way would be growing the tissue or something. That is if the idiot people did not try to stop using the cells that can morph into any tissue.
05:41 PM Loetmichel: stem cells
05:41 PM LeelooMinai: Right
05:43 PM LeelooMinai: Loetmichel: Have you used "magnifying" lens when welding - is that something that works well?
05:43 PM Loetmichel: you mean for the gas stream?
05:44 PM Loetmichel: or for the shield?
05:44 PM LeelooMinai: I mean for any welding - to avoid putting the head too close.
05:44 PM Loetmichel: so for the shield.
05:44 PM Loetmichel: no, i dont need that
05:44 PM LeelooMinai: Right, I mean to see better.
05:44 PM Loetmichel: my glases are good enough
05:44 PM LeelooMinai: Hmm, ok
05:45 PM Loetmichel: also if you can see whats in arm length before you you maybe should get a new optometrist ;)
05:46 PM LeelooMinai: Well, no, I have ok glasses, but, there's a distance that is a bit uncomfortable. The glasses are tuned to the distance between me and the PC screens:)
05:46 PM Loetmichel: I DO use some magnifying glasses for soldering SMT components though: https://www.youtube.com/watch?v=_xnwZU2bd2Q
05:46 PM Loetmichel: s/can/cant
05:47 PM LeelooMinai: Right, with that I have no problems, since if I take the glasses off, put on safety glasses on, my eyes work like a microscope at about 10cm - I can see things that most normal seeing people do not have chance to.
05:47 PM LeelooMinai: Plus I have stereo microscope which is great for that too.
05:47 PM XXCoder: nearvisioned eh
05:48 PM XXCoder: I have fancy goggles that has 10x and 25x zoom :) love those, though pretty rarely used
05:48 PM LeelooMinai: Loetmichel: Can you solder this? :) (250 micron bga dead-bug style): https://www.flickr.com/photos/100017731@N03/18250519673/in/dateposted-public/
05:48 PM XXCoder: actually it has 2x to 25x lens
05:48 PM Loetmichel: LeelooMinai: sure, why not?
05:48 PM XXCoder: I just use 10 on one eye and 25x on other so I can switch as needed
05:48 PM LeelooMinai: Loetmichel: Well, maybe you are better than I thought then:p
05:49 PM LeelooMinai: The wires are bare though - they need to be isolated in 3D space there.
05:49 PM Loetmichel: i assumed so
05:50 PM Loetmichel: i did that a while ago... http://www.cyrom.org/palbum/main.php?g2_itemId=8833&g2_imageViewsIndex=1
05:50 PM Loetmichel: ... INSIDE the eclosure because the PCB was riveted to the back plate.
05:50 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=8836&g2_imageViewsIndex=1 <- can you spot the chip?
05:51 PM XXCoder: lol my soldering skills is VERY crude
05:51 PM LeelooMinai: Loetmichel: What chip...
05:51 PM XXCoder: I'm still waiting for lead and solder sucker wire to arrive so I can finally work on dice roll circuit board
05:51 PM Loetmichel: the aduc
05:52 PM LeelooMinai: Loetmichel: The traces lifted there or what?
05:52 PM Loetmichel: a co-worker slipped with a screwdriver
05:52 PM Loetmichel: and ripped them off
05:52 PM Loetmichel: "loetmichel to the rescue"
05:52 PM LeelooMinai: Loetmichel: That bga I have shown is probably the side of that Analog Devices logo square on that IC. It is 2.5 by 2.5 mm I think:)
05:53 PM XXCoder: man
05:53 PM Loetmichel: ... there is a reason they call me that
05:53 PM Loetmichel: i know
05:53 PM XXCoder: avocodo takes so long to germimate :(
05:53 PM LeelooMinai: To what? :)
05:53 PM XXCoder: its been over a month and its still on boat
05:53 PM Loetmichel: but its more accessible than a chip on a PCB that is back in a military computer enclosure,
05:53 PM Loetmichel: seen the last picture?
05:53 PM LeelooMinai: Loetmichel: Right, I would just try to take it off there.
05:54 PM LeelooMinai: Yes, I can si it there on the right.
05:54 PM Loetmichel: as i said: the PCB was riveted in there... and it was the last we had anyways ;)
05:54 PM XXCoder: https://www.aliexpress.com/item/New-Electronic-Dice-Suite-Electronic-DIY-Kits-Good-Quality/32356456987.html
05:54 PM XXCoder: bet you guys can do this one in sleep lol
05:55 PM LeelooMinai: That's pretty old school:)
05:55 PM Loetmichel: XXCoder: with both eyes closed
05:55 PM Loetmichel: only by feel ;)
05:55 PM XXCoder: bought 2 to learn soldering lol
05:55 PM Loetmichel: i do have a bit of a head start tho
05:55 PM Loetmichel: i am soldering since i was 6 years old
05:56 PM Loetmichel: i am 48 now
05:56 PM XXCoder: dang
05:56 PM Loetmichel: hence the nickname ;)
05:56 PM XXCoder: 41 myself
05:56 PM LeelooMinai: I am 24 - in some undisclosed n-base
05:57 PM Loetmichel: if you didnt get it by now: "Löten" means soldering in german
05:57 PM XXCoder: ahh
05:57 PM Loetmichel: Loetmichel means soldering Michael
05:57 PM LeelooMinai: So you had no choice
05:58 PM Loetmichel: LeelooMinai: let me guess: n is greater than 10 ;)
05:59 PM LeelooMinai: Yes, well, "could be anything":)
06:00 PM Loetmichel: not anything. has to be greater than 4 ;)
06:01 PM XXCoder: greater than 50 less than 52 ;)
06:01 PM LeelooMinai: I think I am 47, but not 100% sure - must calculate:p
06:02 PM LeelooMinai: O, right, I am.
06:03 PM LeelooMinai: But I think my mind did not get a memo that at this age people are supposed to be mature and serious.
06:03 PM Loetmichel: hrhr, i know that feeling
06:03 PM XXCoder: maturity is overrated
06:03 PM * Loetmichel had an appentice fresh from school a while ago. MAN did he had a stick up his ass...
06:04 PM LeelooMinai: Never trust a person without a sense of humour imo:)
06:04 PM LeelooMinai: However lame that sense is.
06:05 PM LeelooMinai: Still better than nothing.
06:05 PM Loetmichel: he always looked at me with that "you are supposed to be the mature and sober part, why have i to be the one?" when i pulled another of my usual stunts involving some bandaid :-)
06:05 PM LeelooMinai: Loetmichel: Did you eventually murder him? :p
06:05 PM Loetmichel: no
06:06 PM LeelooMinai: Meh
06:06 PM Loetmichel: he made it thru the final exams with 100/100 points tho
06:07 PM Loetmichel: he was a fine guy after all, jsut "a bit stiff" and humorless
06:07 PM LeelooMinai: "Maybe had autism"
06:07 PM Loetmichel: no
06:08 PM Loetmichel: just imagine a german official clerk and subtract 20 years and you got him ;)
06:08 PM andypugh: LeelooMinai: I was 47 twice, I got it wrong and spent my 46th year thinking I was 47
06:09 PM LeelooMinai: Right, I sometimes check if it's 2017 or 2007, especially after I wake up:)
06:09 PM Loetmichel: andypugh: usually its the other way around with me... "how old are you?" "42. no wait, that was a few years ago, let me recalculate" ;.)
06:09 PM andypugh: Loetmichel: A quote from somewhere (I can’t find the original source) “The Germans share a common sense of humour. On a strict rota basis”
06:10 PM Loetmichel: rota?
06:10 PM XXCoder: lol https://www.youtube.com/watch?v=ob_ftabABZg that is awesome
06:10 PM phipli: Loetmichel: take it in turns
06:10 PM Loetmichel: ah, so only one sense for all 80 million people ;)
06:10 PM Loetmichel: i get it ;)
06:10 PM phipli: he is being mean
06:10 PM phipli: yes
06:10 PM XXCoder: Loetmichel: youre fine with 42. it IS answer to everything.
06:10 PM Loetmichel: sometimes i think thats right
06:10 PM Loetmichel: that humor thing
06:11 PM LeelooMinai: XXCoder: Right... assuming if you have a river through your backyard:)
06:11 PM Loetmichel: the amount of humorless peolpe in germany is too damn high
06:11 PM XXCoder: sadly I dont but I'm happy to see new power solutions
06:12 PM andypugh: Last Wednesday for an hour 51% of UK power came from renewables.
06:12 PM XXCoder: there is TONS of slow moving rivers.
06:12 PM Loetmichel: especially when i am in the ER again for some "minor lacerations"... and I am the one that does the jokes and the nurses are dead serious ;)
06:13 PM XXCoder: loet heh I dont take inguries seriously enough :P I once cut wrist on part at work
06:13 PM XXCoder: I used cotton and brown tape to stop bleeding
06:13 PM XXCoder: I was p[lanning to keep working
06:13 PM Loetmichel: i used gaffa tape the last time
06:13 PM XXCoder: but coworker took a bit to push me to go to er
06:13 PM Loetmichel: no cotton though
06:13 PM XXCoder: as it turns out it was quite serious, 4 sew
06:14 PM Loetmichel: lst time was this: (caution some minor blood)-> http://www.cyrom.org/palbum/main.php?g2_itemId=16188&g2_imageViewsIndex=1
06:14 PM LeelooMinai: When I was small I was always trying to make people laugh. I even head a cap/head cover that on inside had two buttons sawed that looked like eyes, so I culd reverse it and use like a muppet during church sermons where everyone was trying to be dead serious.
06:14 PM Loetmichel: ... slipped with a deburr tool
06:15 PM XXCoder: ow a bit more serious than my wrist cut
06:15 PM XXCoder: I now has cool badly done sucuide scar on my wrist
06:15 PM Loetmichel: you could see the thumb muscle move in the cut
06:15 PM Loetmichel: was interesting
06:15 PM XXCoder: a little deeper and it'd be very bad bleeder
06:15 PM XXCoder: and little bit to left
06:16 PM LeelooMinai: Or have someone enter the room and say "o, look, a chicken nudget"
06:16 PM Loetmichel: it WAS a bad bleeder. took me half an hour to clean up the mess when i was back at work from the ER
06:16 PM XXCoder: mine wasnt too bad
06:17 PM LeelooMinai: Hmm, I know gloves are often not a good idea with rotating stuff, but welding gloves + an angle grinder, ok?
06:18 PM Loetmichel: funny side note: my bosses wife managed to get the "yellow slip" from the hospital with 6 days "ill at home" written on it and send it to the health insurance to get reimbursed... i only noticed on my next pay slip where it said "6 days ill"
06:18 PM Loetmichel: LeelooMinai: depends on the angle grinder
06:18 PM XXCoder: im still pissed at work L & I
06:18 PM LeelooMinai: I thought "yellow slip" was for mentally ill? :)
06:18 PM XXCoder: I filled out form and I said I missed zero days
06:18 PM LeelooMinai: Or was it yellow papers...
06:19 PM XXCoder: somehow they took that to be WEEK off
06:19 PM LeelooMinai: Loetmichel: Same as the one you had on that picture.
06:19 PM XXCoder: sent me a check, I never cashed it, told em it was in error
06:19 PM Loetmichel: a small one will simply stop if it catches the glove
06:19 PM XXCoder: they kept trying to make me pay back for check I never cashed
06:19 PM Loetmichel: a larger one may tear thru
06:19 PM XXCoder: they finally stopped when they realized I never cashed the damned check lol
06:20 PM LeelooMinai: Hmm... I need to check how much power those grinders even use.
06:21 PM Loetmichel: LeelooMinai: in germany you get a yellow (3)piece of paper from the doctor which has the amount of days on it you are not to be at work.
06:21 PM LeelooMinai: Hmm, 6A/11k RPM
06:21 PM Loetmichel: one of the papers goes to your work, one you have to send to the insurance and one you should keep
06:21 PM LeelooMinai: So 660watt
06:21 PM LeelooMinai: Not sure if that's "small" category...
06:21 PM Loetmichel: and the work gets reimursed for that time by the insurance
06:22 PM Loetmichel: so they still pay your salary but get it back
06:22 PM Loetmichel: LeelooMinai: that IS the small category
06:22 PM Loetmichel: the large ones have 2.3kW ;)
06:22 PM LeelooMinai: ...
06:23 PM Loetmichel: considering i was working again 2 hours after the deburrer slipped i would call that "insurance fraud"... but who am i to know german insurance laws...
06:24 PM XXCoder: wow pretty cool https://youtu.be/sx333SV47SE
06:24 PM Loetmichel: (one of the reasons i am pretty pissed about said boss wife)
06:24 PM LeelooMinai: Loetmichel: Depends on where you are it could be "fraud" or "winning" :)
06:24 PM XXCoder: fraud definitely
06:24 PM XXCoder: LI thought I attempted fraud
06:25 PM LeelooMinai: In that case US president is a fraud too:)
06:25 PM XXCoder: lol
06:25 PM XXCoder: the road/airport line cleaner equipment is interesting
06:26 PM LeelooMinai: I read that he and his son even cheated 100k from some child cancer fundation.
06:26 PM XXCoder: 500k
06:28 PM LeelooMinai: pResident Evil
06:35 PM LeelooMinai: Hmm, they sell welding blankets... I wonder what they are made from.
06:35 PM LeelooMinai: "flame retardant fiberglass"
06:35 PM XXCoder: abestos?
06:35 PM LeelooMinai: Asbestos is banned from most things I think.
06:35 PM XXCoder: it is yeah
06:35 PM XXCoder: btw its still in brake pads
06:36 PM LeelooMinai: XXCoder: Well, I just read 2 days ago that nowadays they can use cut kevlar fibers instead of asbestos in brake pads.
06:36 PM XXCoder: yeah? thats good as abestos is pretty nasty
06:37 PM LeelooMinai: RIght, they were using it as insulation I think in old houses and here it's not allowed any more.
06:37 PM XXCoder: ceiling tiles, so on
06:37 PM LeelooMinai: Right, they use mineral fibers now for those.
06:38 PM LeelooMinai: Or PVC even - I bought one sheet of it, to see if I can machine it. Probablt I can - it's hard on the ourside, but inside is a bit like powder with air space, but still, dense enough maybe.
06:40 PM XXCoder: high rpm maybe?
06:41 PM LeelooMinai: Well, I got once a bit that is supposed to be for plastic from ali - it seems to have one flute, 1/8 - I think I will try with it first.
06:41 PM LeelooMinai: Seems to have huge grove for chip evacuation, so makes sense...
06:44 PM LeelooMinai: Hmm "10 pc PP (Polypropylene) Plastic Welding Filler Rods", weird....
07:13 PM Loetmichel: LeelooMinai: there are even welding blankets made of hollow glass fibres
07:14 PM Loetmichel: light as a feather and you can aim a blowtorch on one side and still touch the other side
07:14 PM LeelooMinai: I bought some 2x4 one - was only $20 - I will make a screen from it.
07:14 PM LeelooMinai: Assuming it will block the arc... If not I will put alu foil on the other side or something.
07:14 PM XXCoder: heh theres better insulation than that, saw one where theres blowtrouch one side and ice is doing well on ither side
07:14 PM XXCoder: expensive though
07:15 PM LeelooMinai: Probably NASA stuff they use on space things.
07:15 PM LeelooMinai: Forgot what it as, but it was ceramic with air inside?
07:16 PM XXCoder: aerogel
07:16 PM LeelooMinai: RIght
07:16 PM Loetmichel: XXCoder: you mean that aeorgel stuff?
07:16 PM XXCoder: https://en.wikipedia.org/wiki/Aerogel
07:16 PM Loetmichel: its fun
07:16 PM Loetmichel: but a bit overrated in domestic use
07:16 PM XXCoder: https://en.wikipedia.org/wiki/Aerogel#/media/File:Aerogelflower_filtered.jpg
07:16 PM Loetmichel: its EXTREMLY hygroskopic
07:17 PM XXCoder: water grabbing right?
07:17 PM Loetmichel: yes
07:17 PM Loetmichel: and it "melts" if it has absorbed enough water
07:17 PM XXCoder: yeah and very brittle otherwise
07:17 PM Loetmichel: yes
07:18 PM XXCoder: specialist uses good but regular too bad no
07:18 PM Loetmichel: yes
07:18 PM LeelooMinai: Would be cool if one could use it inside walls in houses, etc.
07:18 PM XXCoder: theres slightly heavier version that dont have those flaws
07:18 PM LeelooMinai: Well, would be cool in summer, hot in winter:)
07:19 PM LeelooMinai: But probably the cost is too high.
07:19 PM Loetmichel: LeelooMinai: a good half meter of ytong does the same
07:19 PM Loetmichel: and is much cheaper
07:19 PM LeelooMinai: Of what?
07:19 PM Loetmichel: aereated concrete
07:19 PM Loetmichel: ytong
07:20 PM LeelooMinai: But houses are from wood here:)
07:20 PM XXCoder: https://www.youtube.com/watch?v=k8OhJKR3AA4
07:20 PM XXCoder: airloy
07:22 PM LeelooMinai: Hmm, can be machined.
07:22 PM LeelooMinai: And waterproof, yes.
07:24 PM XXCoder: yeah.
07:25 PM Loetmichel: LeelooMinai: if you want a superinsulatiing wooden house: use balsa beams and walls ;)
07:25 PM LeelooMinai: Seems like styrofoam that is also strong (ish)
07:25 PM Loetmichel: styrofoam is a lot denser than that airloy
07:25 PM LeelooMinai: But has same thermal conductivity from that chart they have there.
07:26 PM Loetmichel: i would wager its some kind of stronger plastic foamed up a good more than practical with styrol
07:26 PM LeelooMinai: And from that hammer blow it seems not worse than styrofoam.
07:27 PM Loetmichel: a combination of balsa wood and glass fibre is acutall a funny material...
07:27 PM LeelooMinai: Balsa wood is good for plane models, but never saw homes made from it:)
07:27 PM LeelooMinai: Houses rather.
07:27 PM XXCoder: balsa wood I want to buy some for cnc stuff fun
07:28 PM XXCoder: just need machine working well for that. im far too lazy lately
07:28 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=4897&g2_imageViewsIndex=1 <- made a quadcopter out of it thats probably the lightest one i can make ever
07:28 PM XXCoder: loet idea for you
07:28 PM LeelooMinai: lol, I made sure that my CNC is not yet working
07:28 PM Loetmichel: and still structurally sound
07:28 PM XXCoder: airloy quadcoper
07:29 PM LeelooMinai: XXCoder: That seems what they do everywhere now , just with carbon fibre
07:29 PM LeelooMinai: And I even saw one like this made from that ceiling PVC sheet I got...
07:29 PM LeelooMinai: I think that's why I even got it.
07:29 PM Loetmichel: LeelooMinai: that stuff? http://www.cyrom.org/palbum/main.php?g2_itemId=4830&g2_imageViewsIndex=1
07:30 PM Loetmichel: ... just for comparsion to the balsa ;)
07:30 PM LeelooMinai: THe one I saw was white.
07:30 PM Loetmichel: its aviable in all colours of the rainbow
07:30 PM Loetmichel: 3mm PVC foam sheets
07:30 PM LeelooMinai: Paybe it's not PVC...
07:30 PM XXCoder: I wonder how much airloy quadcoper would weigh lol
07:31 PM Loetmichel: depends on how struturally sound it is
07:31 PM XXCoder: yeah thats the rub eh
07:31 PM Loetmichel: the balsa only worked beacuse it had 2 sheets of 40g/square meter glass fribre laminated on each side
07:32 PM Loetmichel: i cheated a bit :-)
07:33 PM LeelooMinai: Hmm, found it: https://www.lowes.ca/ceiling-tiles/genesis-2-ft-x-4-ft-smooth-pro-white-lay-in-ceiling-tile-common-48-in-x-24-in-actual-475-in-x-235-in_g2461413.html?searchTerm=ceiling-panel
07:33 PM LeelooMinai: Seems PVC
07:33 PM LeelooMinai: Not too expensive
07:33 PM Loetmichel: this one is made of 2mm model plywood: http://www.cyrom.org/palbum/main.php?g2_itemId=5041 <- about twice as heavy as the balsa one but a lot stronger.
07:33 PM XXCoder: yeah
07:34 PM Loetmichel: access denied
07:34 PM Loetmichel: they dont like germans it seems ;)
07:34 PM LeelooMinai: Strange
07:35 PM Loetmichel: XXCoder: still a crash landing results in THAT: http://www.cyrom.org/palbum/main.php?g2_itemId=5198&g2_imageViewsIndex=1
07:35 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=5195&g2_imageViewsIndex=1
07:35 PM XXCoder: wow
07:35 PM Loetmichel: but as i have a CNC mill and the plywood sheets cost next to nothing....
07:35 PM XXCoder: looks pretty good for a major crash
07:35 PM LeelooMinai: Did anyone see tht guy flying on a wuadcopter on some sports event?
07:36 PM LeelooMinai: Well, not quad, but looked like hexacopter I guess.
07:36 PM XXCoder: loet yeah and since its uber repeatable, you can make essentally make couple complete kits in order to rejoin flying if crashed
07:36 PM Loetmichel: i did
07:36 PM LeelooMinai: I was not even sure if it was real or not:)
07:36 PM Loetmichel: it was real
07:37 PM Loetmichel: some fellow canadian did build it iirc
07:37 PM Loetmichel: at least he was speaking french in the video i have seen from the builder
07:38 PM XXCoder: lol fordboy is pretty smart
07:38 PM XXCoder: he wanted to make a camera mount
07:38 PM Loetmichel: XXCoder: i always went to the model airstrip with at least a dozen outriggers in my car... just in case ;)
07:38 PM XXCoder: he grabs alum rod that was feeder down cutoff
07:38 PM XXCoder: he cuts it out and now are cutting it with lathe
07:38 PM XXCoder: loet nice
07:38 PM XXCoder: I tried quadcoper and its not for me
07:39 PM LeelooMinai: XXCoder: You flew on a quadcopter? :)
07:39 PM XXCoder: yeah cheap x5sw lol
07:39 PM XXCoder: umm "on" nope lol
07:40 PM LeelooMinai: XXCoder: I was just going to say that you must be pretty small.
07:40 PM LeelooMinai: I am waiting for Amazon quadcopters, but not sure what's up with that idea.
07:40 PM Loetmichel: i have flown everything from soar planes over big 9 cilinder star motors in double deckers and some "classic" model helicopters... in my youth i even flew the real thing... (my exexexexex boss had one)... multicopters are quite different. Almost relaxing compared to the other models
07:41 PM LeelooMinai: If only those things were less noisy.
07:41 PM Loetmichel: MAAAN was i young once... -> http://www.cyrom.org/palbum/main.php?g2_itemId=3542&g2_imageViewsIndex=1
07:41 PM LeelooMinai: Loetmichel: Seems at least 50kg younger to me:)
07:42 PM Loetmichel: also 60kg younger than me NOW ;)
07:42 PM LeelooMinai: Yes, that's what I wrote:p
07:42 PM Loetmichel: ah, to me. not than me ;)
07:43 PM Loetmichel: sorry
07:43 PM XXCoder: deaf can be pilot but it isnt easy
07:44 PM Loetmichel: to be honest: that robinson R2 wouldndt have me and my ex boss now
07:44 PM LeelooMinai: Or probably safe...
07:44 PM Loetmichel: wouldnt take off
07:44 PM XXCoder: LeelooMinai: actually deaf tend to be safer driver
07:44 PM SpeedEvil: LeelooMinai: that does however make it safe
07:44 PM XXCoder: no audio to depend on means look around more
07:44 PM XXCoder: just that pilots need to commucate to tower
07:45 PM Loetmichel: morse code to hand?
07:45 PM Loetmichel: could work`
07:45 PM XXCoder: no copilot
07:45 PM XXCoder: thats why its quite rare deaf pilot, never net one so far but I know in least one exists
07:45 PM LeelooMinai: Maybe statistically, due to other people being not-safe, but logically in a situation when hearing something could save you, you will be worse.
07:45 PM Loetmichel: IF the tower can "speak" morse ;)
07:45 PM XXCoder: (small craft not big ones)
07:47 PM XXCoder: Loetmichel: I met deaf musican group
07:47 PM XXCoder: couldnt know if they was good but hearing folk there said it was quite good
07:48 PM LeelooMinai: XXCoder: Sounds like prelude to some joke...
07:48 PM LeelooMinai: "uit the hearing folk were blind, so not sure if they were at the right event"
07:48 PM XXCoder: uhh sure... because they deaf. HAHHAHAHAAA :P
07:49 PM LeelooMinai: Well, "deaf musician group" is a bit weird:)
07:49 PM XXCoder: yeah.
07:49 PM XXCoder: isterments only no vocal
07:51 PM LeelooMinai: I remember reading some short scifi story when I was small where alien race landed on Earth and was trying to communicate with people. Or rather people were trying to communicate. They tried everything and finally the aliens responded where a big band of people started playing for a long time.
07:52 PM LeelooMinai: But flew of later and aliens wrote in the log that they encountered some civilisation, but it was very primitive - at some time they managed to communicate through olfactory means, by smelling badly, but that was most they could do.
07:53 PM XXCoder: lol
09:41 PM XXCoder: facepalm. https://www.geeksaresexy.net/wp-content/uploads/2016/09/math2.jpg
09:43 PM LeelooMinai: It was you buying?
09:43 PM XXCoder: nah
09:43 PM XXCoder: just that addition is very simple
09:44 PM LeelooMinai: Yes, well, not if you are high and try to sell stollen stuff for example:p
09:45 PM XXCoder: maybe maybe not
09:45 PM XXCoder: not all morons are high
09:57 PM XXCoder: lol https://youtu.be/Tc_JWE_ypEk
09:57 PM XXCoder: 10,000 chickens vs 20 t-rex
10:29 PM pink_vampire: hi
10:30 PM XXCoder: hey pink_vampire
10:30 PM XXCoder: been eons since you was last here
10:30 PM XXCoder: hows ya
10:31 PM pink_vampire: I know. long time..
10:31 PM XXCoder: whats you been doing?
10:32 PM pink_vampire: non cnc stuff
10:33 PM XXCoder: cool
10:33 PM LeelooMinai: Lame... I was raging at 480p RobotWars season 6 episodes, but now I see they are from 2003 and BBC did not even had HD up to 2006...
10:33 PM LeelooMinai: Somehow I thought that HD was the thing much earlier:)
10:34 PM XXCoder: nah
10:35 PM pink_vampire: I did some 3d machining, and I'm using the mill as a mini lathe
10:35 PM LeelooMinai: Still, they could remaster the original tapes or what they have there - I somehow doubt that filmed everything at that low res, but I may be wrong.
10:35 PM Tom_L: you're just spoiled
10:36 PM XXCoder: manual machining nice
10:36 PM XXCoder: LeelooMinai: its HARD to remaster tapes of certain era
10:36 PM XXCoder: I thought they would never make HD of next generation star trek but they did. evenually.
10:36 PM LeelooMinai: Well, ok, but those are not like 1930s black-white film tapes that need to be colorized, etc.
10:36 PM pink_vampire: maybe they just upscale the resolution
10:37 PM XXCoder: pink sadly data just isn't there
10:37 PM XXCoder: so they found a way to figure additonal data from what exists so its better but not as good as HD
10:38 PM LeelooMinai: The other thing is, I don't know if shows like that in 2000+ were filmed digitally or not.
10:38 PM LeelooMinai: If not, the resolution probably would be there.
10:39 PM XXCoder: yeah. transition point it can be hard to tell if it was or not
10:39 PM XXCoder: I found it funny that its easier to make HD version of older shows like orginial star trek than TNG because old tapes has plenty of resolution just downscaled to tv then
10:39 PM XXCoder: while TNG what you see is what you get on tape which isnt as good
10:40 PM LeelooMinai: RIght, well, unless the film degrades physically.
10:41 PM XXCoder: think that was part of problem
10:41 PM pink_vampire: what are the most common inserts with positive rake?
10:43 PM LeelooMinai: pink_vampire: Should have asked about chicken instead:p
10:43 PM XXCoder: heh sadly at work its "use this tool"
10:43 PM XXCoder: so I dont know
10:44 PM XXCoder: omg they will finally resolve cliffhanger at end of stargate universe
10:44 PM XXCoder: not as tv show but cartoon but hey
10:45 PM pink_vampire: do you think I will be able to use a VNMG tool on my mill as a lathe?
10:46 PM XXCoder: yeah
10:46 PM XXCoder: mount it on tab;e
10:46 PM XXCoder: you'll have to figure how to securely do that
10:47 PM XXCoder: heh someone here once menioned that they had 4 lathe tools mounted on table to make part on mill acting as lathe
10:47 PM pink_vampire: I think just to hold it in the vise
10:50 PM XXCoder: I dont know how much force tool experences
10:51 PM pink_vampire: now I work with hss blade.
10:51 PM pink_vampire: and i hate it
10:58 PM XXCoder: pink my cnc router project has stalled
10:58 PM XXCoder: I just cant get enough willpower to actually work on it.
11:07 PM XXCoder: pink_vampire: check this out https://www.youtube.com/watch?v=xF8erDoJlsY
11:12 PM LeelooMinai: Hmm, another thing I like with F360 - was CADing something, then got a message that new update is ready: https://www.autodesk.com/products/fusion-360/blog/may-30-2017-update-whats-new/
11:12 PM LeelooMinai: And they have those every month.
11:17 PM pink_vampire: XXCoder: !!!!!!!!!!!!!! https://t3.ftcdn.net/jpg/01/18/47/70/240_F_118477076_5ulKcqxP385zLDwDjJPUXuqPpjR5AJF5.jpg
11:17 PM XXCoder: lol
11:17 PM XXCoder: I later made game logo engrave for my nephew. nothing since then
11:17 PM pink_vampire: XXCoder: The video look awesome!!!!
11:18 PM XXCoder: yeah. next video not so awesome and boring lol
11:18 PM pink_vampire: no...
11:18 PM pink_vampire: I sooo happy for you that you have your machine up and running!
11:19 PM XXCoder: it is running but electrics is all over and messy. I have parts of electrics box ready but couldnt get enough willpower to make it
11:20 PM pink_vampire: if you need help, I will be happy to help you.
11:20 PM XXCoder: thanks
11:20 PM XXCoder: im just tired of being unable to do anything
11:20 PM XXCoder: I really need to see doc and find out
11:22 PM pink_vampire: it is easier then you think
11:22 PM XXCoder: yeah the p[roblem is me not project itself
11:22 PM pink_vampire: make a list of the stuff that you need to do
11:23 PM LeelooMinai: It's point #1 on his current list:p
11:23 PM XXCoder: lol essentally
11:25 PM roycroft: i took my 3 jaw apart today to see if i could get it working more smoothly
11:25 PM roycroft: there were a number of chips in it, and the scroll has some burrs
11:26 PM roycroft: that was encouraging - i think when i get rid of the burrs and finish cleaning/reassembling, it will operate pretty smoothly
11:26 PM roycroft: someone had lubed it with grease, which explains the chips
11:26 PM LeelooMinai: I saw a video where guy was making Chinese chuck for lathe better.
11:27 PM LeelooMinai: Brought it from not so good to pretty good, by fixed some issued due to those being cheap.
11:27 PM LeelooMinai: by fixing*
11:28 PM LeelooMinai: Maybe some useful tricks are there: https://www.youtube.com/watch?v=wKnvZnxXRaY
11:42 PM XXCoder: roycroft: grease is bad in 3 jaw?
11:43 PM pink_vampire: I need help / idea about part design / manufacturing.
11:44 PM XXCoder: ask away
11:46 PM pink_vampire: it an LED strip cover
11:46 PM pink_vampire: I'm taking a picture
11:50 PM pink_vampire: http://i.imgur.com/TOEV82R.png
11:50 PM XXCoder: hmm yeah what about those? you want to make similiar or?
11:50 PM pink_vampire: those are the original parts, need about 30 of them
11:51 PM pink_vampire: it is a cover for led strip
11:51 PM XXCoder: yeah you want more of same right?
11:52 PM pink_vampire: there is a "rail" with 2 grooves that the covers slide in
11:52 PM XXCoder: if I recall those are usually extruded?
11:52 PM XXCoder: or maybe mold cast
11:52 PM pink_vampire: yeah, those are extruded
11:53 PM XXCoder: I dont think its cost effective for you to build an extruder
11:53 PM XXCoder: mold casting may be best option
11:53 PM XXCoder: since you has 2 you could make mold from em
11:53 PM pink_vampire: what about machining
11:53 PM XXCoder: wouldnt be as clean finish unless it is flame polishable
11:54 PM pink_vampire: frosted look is fine
11:54 PM XXCoder: well its not too bad if you do it this way
11:54 PM XXCoder: sheets is wider than final length by maybe a inch
11:55 PM XXCoder: engrave one side, then using the ends bolts, re-align on other side
11:55 PM pink_vampire: but how to i make the curve?
11:55 PM XXCoder: then fengrave it again, adding the tabs
11:55 PM XXCoder: final step would be heated into mold
11:55 PM XXCoder: you could make curved mold with mill also
11:55 PM pink_vampire: sounds like aloooot of work
11:56 PM XXCoder: I'd think outwards mold is easier than inwards
11:56 PM XXCoder: not really
11:56 PM XXCoder: you'd need to cut sections of plastic, all inch wider so it has spots you can bolt into fixture
11:56 PM XXCoder: manually cut off all finisged parts, then heat mold each
11:59 PM pink_vampire: by mold you mean to extrud it?
11:59 PM XXCoder: nah
