12:01 AM MacGalempsy: im loading up a cool one
12:03 AM MacGalempsy: right now we are drilling silty limestone
12:03 AM pink_vampire: where are you drill?
12:03 AM MacGalempsy: in central oklahoma
12:06 AM Mac-Phone: srry dq
12:07 AM Mac-Phone is now known as MacGalempsy
12:10 AM MacGalempsy: almost done loading
12:11 AM pink_vampire: MacGalempsy: it is the eco pad?
12:12 AM MacGalempsy: eco?
12:13 AM pink_vampire: it's an oil well drill that can move to the next hole.
12:14 AM MacGalempsy: yes.
12:14 AM MacGalempsy: it has tracks and can roll about 75ft or so
12:14 AM pink_vampire: http://www.clr.com/operations/technologies/eco-pad
12:15 AM MacGalempsy: the holes are 30ft apart, so thos rig can do 6 woth the right tracks
12:15 AM MacGalempsy: you know clr?
12:17 AM pink_vampire: just from google
12:18 AM pink_vampire: how it is drill to the side?
12:26 AM pink_vampire: brb
12:39 AM hazzy: GN8
12:43 AM XXCoder: now myfordboy got 3d printer lol
12:48 AM Mac-Phone: this loader sucks
12:48 AM Mac-Phone: ?
12:48 AM XXCoder: https://www.youtube.com/watch?v=iJxNK1enlZ4
12:51 AM Mac-Phone: my cousin got one from his wife. it makes decent prints but the he's been acting like hes on the leading edge
12:51 AM Mac-Phone: i just sit back and roll my eyes
12:52 AM XXCoder: it would be, few years ago
12:55 AM Mac-Phone: yeah.
12:55 AM Mac-Phone: the crappy part is his printer makes nicer prints than mine
12:55 AM XXCoder: mine dont really work well
12:56 AM XXCoder: it needs better fan cooling
12:57 AM Mac-Phone: i need CaptHindsight to sell me a factory second sls ;)
12:57 AM XXCoder: I doubt capt would sell me anything
12:57 AM Mac-Phone: cuz u are broke?
12:57 AM XXCoder: last time we talked he went off and pissed off at me and I still dont know what the heck he was talking about
12:58 AM IchGucksLive: morning from germany
12:58 AM XXCoder: hey ich
12:58 AM Mac-Phone: lol.
12:58 AM XXCoder: so I added him to ignore
12:58 AM Mac-Phone: buenos dias
12:58 AM Mac-Phone: that sucks
12:58 AM IchGucksLive: Mac-Phone: South america ?
12:59 AM XXCoder: it sucks but I dont need people like him geting pissed off at me and doesnt tell me whats going on
12:59 AM Mac-Phone: spanish, but i started learning italian last month
12:59 AM IchGucksLive: lots of people out of spain
12:59 AM Mac-Phone: its all just dust in the wind dude
01:04 AM IchGucksLive: im off to garden
01:06 AM XXCoder: indeed
01:06 AM XXCoder: I arent even angry to him, just dont need any nonsense
01:33 AM Mac-Phone: so borig tonight. time to play darts
01:34 AM XXCoder: same
01:34 AM XXCoder: except darts part
01:35 AM XXCoder: ls
02:14 AM t12_: http://radio.garden
02:23 AM Deejay: moin
02:24 AM XXCoder: yo
03:11 AM XXCoder: yo
03:33 AM Mac-Phone: +yo
03:34 AM XXCoder: yo^10
03:34 AM Mac-Phone: ♡
03:34 AM Mac-Phone: Make me something
03:34 AM archivist: sudo make me a sammich
03:34 AM Mac-Phone: with your router.
03:35 AM Mac-Phone: i need a custom darts box
03:35 AM XXCoder: Warning: You are not a sudo user. Logged for administor.
03:35 AM Mac-Phone: archivist - being in the UK, you should establish the Rhenium Darts market. high dollar
03:36 AM Mac-Phone: if it works anywhere it will be there
03:36 AM XXCoder: 1 am is little late for noisy cnc router cutting
03:36 AM Mac-Phone: oh, i expect you to put in a bunchnof design hours, so you can do it around 10am
03:37 AM XXCoder: lol
03:37 AM Mac-Phone: :D
03:38 AM Mac-Phone: the rhenium dart barrel is more dense than tungsten, but would retail at like $300+ per set
03:38 AM XXCoder: osmium ;)
03:38 AM Mac-Phone: once you getba few pros, im sure ppl would buy into it
03:39 AM Mac-Phone: https://flic.kr/p/VV7hw4
03:46 AM XXCoder: fire.
03:46 AM XXCoder: im latter type https://www.dopl3r.com/memes_files/there-are-two-types-of-people-during-summer-by-becky-barnicoat-qjEtq.jpg
03:46 AM Mac-Phone: they forgot to choke it back. lol
03:47 AM Mac-Phone: we werr surprised they didnt burn dow the powerlines. also a few pallets caught on fire
04:04 AM phipli: morning
04:07 AM XXCoder: ow
04:07 AM XXCoder: hey phipli
04:36 AM phipli: hey XXCoder
04:36 AM XXCoder: whats up
04:36 AM phipli: not a whole lot :)
04:36 AM phipli: this morning I'm going to try and remove the bearings in my lathe headstock
04:37 AM XXCoder: same. nothingtend to happen at 2 am lol
04:37 AM Deejay: you night owls ;)
04:37 AM phipli: was struggling to find something the right size to place against them yesterday
04:37 AM phipli: Deejay: 10am :)
04:37 AM Deejay: oh, phipli, where are you from?
04:37 AM phipli: UK
04:38 AM Deejay: ah! 11 am here
04:38 AM Deejay: germany
04:38 AM * phipli waves across the sea
04:38 AM Deejay: hehe
04:38 AM phipli: my girlfriend has a German degree, and lived over there for a while
04:38 AM Deejay: nice
04:38 AM phipli: but my grasp of the language is limited to words with common roots
06:06 AM jthornton: morning
06:06 AM XXCoder: hey the j
06:10 AM jthornton: what's up this morning
06:10 AM XXCoder: eating some popcorn. you?
06:10 AM jthornton: coffee
06:12 AM XXCoder: eating coffee cool
06:17 AM jthornton: https://coffeecityusa.com/137-candy
06:17 AM XXCoder: you could try coffest drink
06:18 AM XXCoder: I still have 4 left, my body dont really react well with coffee so I had to stop
06:18 AM jthornton: what is that?
06:18 AM XXCoder: soylent with coffee
06:19 AM XXCoder: 400 kcal
06:29 AM phipli: soylent green?
06:29 AM XXCoder: nh soylent black for coffiest
06:29 AM phipli: good. Mr. Heston wouldn't approve
06:30 AM XXCoder: it wasnt people in book
06:31 AM phipli: haven't read the book
06:31 AM XXCoder: admittly, I didnt either but evenually I will.
06:32 AM XXCoder: im currently reading book of amber
06:32 AM XXCoder: 10 books in one, and 1910 pages
06:32 AM XXCoder: I read first 5 books before but havent read last 5
06:36 AM phipli: this?
06:36 AM phipli: https://en.wikipedia.org/wiki/The_Chronicles_of_Amber
06:37 AM XXCoder: yeah
06:37 AM phipli: not read them
06:37 AM XXCoder: I'm not bothering with presequels, it was against author will and wish
06:37 AM XXCoder: you should, very good and unique fantasy type but also includes realistic earth (tech and everything)
07:02 AM phipli: ordered some cheap feeler gauges to use as shims
07:02 AM XXCoder: yeah used that like that bunch of times at work also
07:03 AM phipli: easiest way to get a strip of 0.02mm steel :)
07:09 AM jthornton: I wonder if the slot in the bearing was an added feature to "fix" a worn bearing?
07:15 AM phipli: jthornton: they were built like that
07:15 AM phipli: someone not very handy has had it to bits before though
07:16 AM phipli: some idiot tried to run the spindle through the bearings with the key still in place
07:17 AM jthornton: lol
07:17 AM XXCoder: heh I probably'd make that mistake :P
07:17 AM phipli: they've also added a dimple to the spindle to stop the bull gear slipping...
07:17 AM XXCoder: I once left toolchange wrench on bridgeport top
07:17 AM phipli: but took two tries
07:18 AM phipli: XXCoder: urgh :(
07:18 AM XXCoder: it turned and smashed into box by it. it had 3 other dents, I asked supervisior about it. its common mistake for newie workers on training
07:18 AM phipli: thankfully my mill has a belt drive - although I've not needed it for "forgot to remove the locking bar" yet
07:20 AM phipli: he didn't get you to make a new box then :)
07:20 AM XXCoder: it was very minor dent
07:21 AM XXCoder: just still not good idea lol
07:27 AM phipli: sigh. why is phosphor bronze so expensive
07:27 AM XXCoder: because they dont like you
07:27 AM XXCoder: ;)
07:27 AM phipli: thought as much
07:28 AM phipli: trying to find a piece with about the right size hole in the middle so I don't have too pay for too much waste material
07:29 AM phipli: but it doesn't seem to work, because there is someone selling solid round bar for less than the guy selling the same OD hollow bar!
07:29 AM XXCoder: as well as go hollow
07:29 AM XXCoder: then melt chips into more rod or material
07:32 AM XXCoder: err
07:32 AM XXCoder: I mean go solid
07:32 AM Phiplii: heh.
07:32 AM XXCoder: yeah melt them nonexistant chips
07:36 AM Phiplii: 1000°C
07:41 AM XXCoder: pretty high
07:51 AM phipli: tricky in the kitchen
07:59 AM * jthornton is not having any success getting the ntp time with the enc28j60
08:00 AM XXCoder: what happens?
08:00 AM jthornton: Failed to configure Ethernet using DHCP
08:01 AM XXCoder: weird
08:01 AM jthornton: yea two different programs give the same result
08:02 AM Tom_itx: maybe it's wiring then
08:02 AM XXCoder: you know its connected in physical layer?
08:02 AM jthornton: no, I can make a web page that says Hi JT
08:02 AM jthornton: and I can view that web page with my browser
08:02 AM phipli: this any use? https://github.com/thiseldo/EtherCardExamples/blob/master/EtherCard_ntp/EtherCard_ntp.ino
08:02 AM XXCoder: so its networking is working but ntp doesnt?
08:04 AM phipli: are you still using the ATMEGA168 based Nano? Does it have enough RAM?
08:04 AM jthornton: no, I have the 328 plugged in
08:05 AM phipli: http://forum.arduino.cc/index.php?topic=171941.0
08:05 AM jthornton: that example has some weird libraries
08:05 AM phipli: true
08:05 AM phipli: might be for a proprietary board
08:06 AM phipli: second link is a bit simpler
08:07 AM jthornton: error: variable 'website' must be const in order to be put into read-only section by means of '__attribute__((progmem))'
08:07 AM jthornton: char website[] PROGMEM = "blog.cuyahoga.co.uk";
08:07 AM jthornton: ^
08:07 AM jthornton: debug("Quick time check...");
08:07 AM jthornton: ^
08:07 AM jthornton: exit status 1
08:07 AM jthornton: variable 'website' must be const in order to be put into read-only section by means of '__attribute__((progmem))'
08:07 AM phipli: ooh, this one : http://www.wennekes.info/scripts.php?chapter=Arduino&article=NTP%20Client%20-%20ENC28J60
08:08 AM phipli: yeah, the way PROGMEM works changed a little a few versions back
08:08 AM jthornton: I looked at that one earlier and he used pin 8 for SS for some reason and the rest use pin 10
08:09 AM phipli: shouldn't be an issue
08:09 AM phipli: just switch it
08:09 AM phipli: if it is defined in the code
08:10 AM phipli: I have an ENC28J60 somewhere...
08:11 AM jthornton: hmm the last one has a compile error about a variable not being declared
08:13 AM jthornton: [testDHCP]MAC: 1:2:3:4:5:6Resolve dhcp ...Trying to resolve DHCP attempt nr. 1
08:13 AM jthornton: oh wait it's working
08:14 AM XXCoder: yay
08:15 AM jthornton: but printing out random numbers not the real time and date
08:16 AM XXCoder: maybe its raw datetime
08:16 AM phipli: jthornton: do a find and replace of "lcd" with "//lcd"
08:16 AM jthornton: no, the code wants a RTC as well as the ethernet
08:17 AM jthornton: did that, there was only a few
08:17 AM phipli: jthornton: I thought you had the RTC attached sorry - thought that was what you were doing
08:18 AM jthornton: it's attached to the other 328 lol, I can move the wires over when I get back from breakfast
08:18 AM phipli: :)
08:21 AM jthornton: ok wired it up but it hangs trying to resolve dhcp
08:22 AM jthornton: DHCP failed
08:22 AM jthornton: My IP:0.0.0.0
08:22 AM jthornton: gotta run now
08:23 AM phipli: kk
08:23 AM phipli: see you later
09:41 AM phipli: jthornton: my setup (same stuff as yours) does the exact same thing
09:42 AM phipli: ENC28J60 + Nano + RTC
10:06 AM Loetmichel: sooo, finnaly found the bolts that hold the seats in the car... nex problem: the "new" rear seats have heardrest. the old hadnt... now i miss the internal "holders" for the headrests. *grummel*
10:06 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16688
10:06 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16691
10:06 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16694
10:06 AM Loetmichel: I still have to mount the front seats, we'll see what surprises will emerge there... :-( (but now i have to drink a gallon or so, its hot and humid outside, i am drenched in sweat :-( )
10:06 AM Deejay: 17°C here
11:55 AM Loetmichel: sooo, done with mounting the new seats into the BMW 318i... sweating so luch i nave no dry rag on me no more... and i will have to dismantle the front seats again... both belt tightener pyro plugs were missing, so now the airbag indicator is lit... have to mount the tighteners from the old seats some time before the next MOT... pics here: http://www.cyrom.org/palbum/main.php?g2_itemId=16688
11:55 AM Loetmichel: (just click on "nächste" until there are no more pics or click on the picture to see a bigger resolution.)
11:57 AM phipli: JT-Shop: jthornton : got NTP working with ethernet
11:57 AM phipli: and the RTC
12:05 PM pink_vampire: https://www.aliexpress.com/item/GRBL-DIY-CNC-2418-CNC-machine-working-area-16x10x4-5cm-3-Axis-Pcb-Milling-Machine-Wood/32718908094.html?spm=2114.01010208.3.149.sZPjmX&ws_ab_test=searchweb0_0,searchweb201602_1_10152_10208_10065_10151_10130_10068_5330015_10136_10137_10060_10131_10155_10062_10132_10133_437_10154_10056_10055_10054_10059_303_100031_10099_10103_10102_10096_5220017_10052_10053_5320017_10
12:07 PM phipli: very cheap
12:09 PM pink_vampire: https://www.youtube.com/watch?v=Cr5Rp8TR448
12:24 PM LeelooMinai: I see Haas influences there:)
12:32 PM IchGucksLive: hi
12:35 PM pink_vampire: hi
12:46 PM IchGucksLive: im finishing the Harvest dataanalysys
01:00 PM phipli: IchGucksLive: what sort of thing do you look for in the data?
01:00 PM IchGucksLive: optimise faults errors
01:00 PM IchGucksLive: its now up to 214pages
01:00 PM phipli: pink_vampire: what are they cutting? Cheddar or Stilton?
01:01 PM IchGucksLive: does someone kow a graphical programm on ubuntu to add bookmarks to a pdf
01:01 PM LeelooMinai: They are cutting the price:)
01:02 PM jym: IchGucksLive: Most pdf readers have that ability. If not, try looking for a simple editor that can index PDF's
01:04 PM LeelooMinai: Well, depends what "bookmarks". Readers cannot add PDF bookmarks into the document itself.
01:04 PM IchGucksLive: jym: i know i did it last oktober on this mashine
01:05 PM IchGucksLive: so it is there i only need to find it
01:08 PM jym: IchGucksLive: ah, ok. sorry, cant help further.
01:08 PM IchGucksLive: master pdf
01:18 PM CaptHindsight: https://www.youtube.com/watch?v=kNqEdF-KV3c upside down SLS printing
01:19 PM jym: CaptHindsight: Pfff, inside out printing if you want to impress me ;)
01:22 PM CaptHindsight: https://www.youtube.com/watch?v=-qbLxL3KBKE look at how unsmooth the powder is spread across the build platform
01:24 PM CaptHindsight: this is done to lower the resolution to meet FDM quality
01:25 PM CaptHindsight: the speed of the technology has also been reduced by replacing the speedy galvo system with a XY belt driven Cartesian movement
01:26 PM CaptHindsight: and also with a low power laser
01:29 PM IchGucksLive: im off GN(
01:29 PM IchGucksLive: im done seeing only numbers and charts
02:41 PM JT-Shop: phipli: Cool!
03:14 PM JT-Shop: BlueWing brakes saved my bacon again today... those brakes are awesome!
03:27 PM phipli: someone pull out in front of you?
03:28 PM phipli: how straight does it stop?
03:28 PM phipli: or are you talking about an emergency stop?
03:30 PM JT-Shop: deer jumped out in front of me I missed it by a foot
03:30 PM XXCoder: missed free meal for week by foot
03:30 PM XXCoder: ;)
03:30 PM JT-Shop: the BlueWing stops faster and straighter than anything I've driven before
03:31 PM JT-Shop: yes emergency as in grab all the brake you can NOW!
03:31 PM JT-Shop: I just loaded the code and it says it uses 102% of my memory :(
03:32 PM phipli: ??
03:32 PM phipli: I have it loaded into a nano
03:32 PM phipli: ah
03:33 PM jym: JT-Shop: extra memory you didn't even know you had!
03:33 PM phipli: what does it say under Tools>Processor...
03:33 PM * JT-Shop smacks forhead...
03:33 PM phipli: it only uses 47% on mine
03:33 PM phipli: let me guess...
03:34 PM phipli: someone still had 168 selected?
03:34 PM JT-Shop: yep your right
03:34 PM JT-Shop: and I knew what you were going to type lol
03:34 PM * phipli chuckles (because he's done it too)
03:44 PM XXCoder: wow
03:44 PM XXCoder: now 60 building failed inspectsions at uk
03:44 PM XXCoder: no building have passed inpsection so far. wow.
03:47 PM jym: XXCoder: CONGRATS 100% RECORD
03:48 PM XXCoder: normally I'd laugh but this is huge risk to residents :( bunch of people died in recent building fire
03:48 PM XXCoder: thats why theyre checking all buildings in fact
03:51 PM JT-Shop: phipli: should the sketch print something from time to time?
03:53 PM phipli: to serial yes
03:53 PM phipli: do you have your console set to 115200 baud?
03:53 PM JT-Shop: it prints the expected EhterCard NTP Client then RTC present
03:53 PM JT-Shop: I changed it to 9600
03:54 PM phipli: do you have ethernet plugged in?
03:55 PM phipli: what CS pin are you using?
03:56 PM phipli: do you have the reset pin connected to the nano's reset?
03:57 PM phipli: looks like this on mine : http://elephantandchicken.co.uk/projects/EtherNTP.png
03:58 PM JT-Shop: ah cs is on 10 and I'd bet this is the one that uses 8
03:59 PM phipli: you can change it
04:00 PM phipli: line 149
04:00 PM phipli: but yes, currently set to 8
04:00 PM * phipli creates a constant to set the CS pin...
04:02 PM phipli: byte rev = ether.begin(sizeof Ethernet::buffer, mymac, **this is the cs pin**);
04:05 PM JT-Shop: aye that fixed it now to study the working code
04:06 PM jym: What are you guys playing with?
04:07 PM phipli: spaceships
04:07 PM jym: oh, Zzzzzzz
04:07 PM phipli: *getting NTP on an arduino with an ethernet module
04:07 PM JT-Shop: time travel
04:08 PM phipli: if we can get time travel sorted, we can just skip forward to pick up the spaceship
04:08 PM jym: phipli: Sounds like a waste, should use a ESP8266 instead.
04:08 PM phipli: only need to work on the one
04:08 PM phipli: jym : I did
04:09 PM jym: phipli: you said arduino+ethershield != esp =)
04:09 PM phipli: jym : I built something using an ESP to get NTP...
04:09 PM jym: gotcha
04:09 PM phipli: JT-Shop is playing with ethernet and so I found the same module to give him a hand with code
04:10 PM phipli: JT-Shop's esp8266 module hasn't arrived yet :)
04:10 PM phipli: well, and ESP-01 has, but there not as fun as the NodeMCUs or D1 Minis
04:10 PM phipli: *they're
04:12 PM jym: I have yet to play with my mini's, need to solder on the headers for one
04:12 PM phipli: probably my preferred MCU at the moment
04:12 PM phipli: although I haven't played with my ESP32 properly yet
04:13 PM jym: For embedding into projects, they're great.
04:13 PM jym: less component count. but usb cables aint cheap, just as expensive ironically
04:14 PM phipli: there is a program over wifi setup for them
04:14 PM jym: Sory, I mean to sell and include to power the project.
04:16 PM phipli: do you build things to sell using them?
04:18 PM jym: I'm trying to, logistics has always been my nemesis. It bugs the fuck out of me that a uC is $1 and a fucking cable is $2 (longer 6ft ones)
04:19 PM Tom_itx: cable not included
04:19 PM jym: Damn able is almost 20-25% of the margin here.
04:20 PM jym: Tom_itx: Yeah, have to, connectors alone cost just as much unless you are buying millions of them
04:20 PM Tom_itx: yeah connectors sometimes cost more than the main components
04:20 PM jym: even a 9v battery clip is expensive ironically
04:21 PM Tom_itx: you can find those that solder to the board
04:21 PM jym: (comparitevely that is)
04:21 PM Tom_itx: i wouldn't go that route on a 9v battery though
04:22 PM jym: Tom_itx: sometimes I can't get the connector out of the packag, so I need cable.
04:22 PM jym: It's okey, I'm semi whing, but so hard to find when searching thru ali
04:30 PM LeelooMinai: jym: Forget the $1 uC vs $2 cable realization. For many projects it's hardware = 20% cost and 80% is in firmware - many people are entraped this way too:)
04:35 PM LeelooMinai: lol: "Betsy DeVos Picks Student Loan CEO To Run Student Loan System"
04:37 PM XXCoder: conflict of interest aloy!
04:37 PM LeelooMinai: Monty Python days
04:38 PM XXCoder: its selections like that that I feel the debate for selection starts with "what is worse possible person for this?"
04:39 PM LeelooMinai: They also have big oil company owners in charge of envrironment protection:)
04:45 PM LeelooMinai: Apparently they fired 38 scientists from that panel, and then decided that well, since the replacements are not ready yet, they will cancel all meeting until they are there...
04:46 PM XXCoder: probably looking for stoogie scientists
04:46 PM LeelooMinai: Well, following the tendency, the logical choice would be creationists or someone like that.
04:47 PM XXCoder: it would backlash on them badly if they were flat worlders too
04:47 PM XXCoder: "hey dont drill ytou will punch though earth!
04:47 PM LeelooMinai: XXCoder: I fotgot: what country do you live in?
04:48 PM XXCoder: hollow earth would be same. "oh noes that would deflate earth!"
04:48 PM XXCoder: usa
04:48 PM XXCoder: land of the orange one
04:48 PM LeelooMinai: O man, condolences then:)
04:48 PM XXCoder: lol
04:50 PM LeelooMinai: I loled how Resident Troll started campaigning again and was bragging how smart he is and told the same people that laughed at green energy that now he will put solar panels on the wall...
04:50 PM XXCoder: also LOL http://s3.crackedcdn.com/phpimages/article/6/5/3/617653_v2.jpg
04:51 PM pink_vampire: O_o
04:52 PM XXCoder: lee I so want solar power :(
04:52 PM XXCoder: but dont own land here and solar is little bit expensive to have temp install
04:52 PM LeelooMinai: Right, I remember it: would be too absurd even for a comedy. The director would say "Come on! Potus and South Arabia holding a glowing world orb? Who will buy it." :)
04:53 PM XXCoder: that thing still mystifies me
04:53 PM LeelooMinai: Well, I just ordered 600watt micro inverter for my two 200 watt panels that sit in the basement for 3 years...
04:53 PM LeelooMinai: ... because felt it's a bit sad:)
04:53 PM XXCoder: 400w that would be enough for pretty good amount of house electicity
04:53 PM XXCoder: hardline for peaks
04:55 PM LeelooMinai: It's a grid tie one, and has island protection, but China, so technically it's not certifed, but certified are expensive and monitoring options are extra money, etc. And this one has RF monitoring module with RS232 port + monitoring app for free.
04:56 PM LeelooMinai: So I decided to try it, to at least make some use of those panels and gather some data as to insolation in my backayrd etc. And the house uses at least 600wat at any moment.
04:57 PM XXCoder: yeah that covers good 2/3 of it
04:57 PM XXCoder: im pretty sure this house uses more
04:58 PM LeelooMinai: Here's the thing I got: https://www.aliexpress.com/item/Grid-Tie-Micro-Solar-Inverter-WVC600-With-Power-Line-Communication-MPPT-pure-sine-wave-solar-inverter/32525167097.html
04:58 PM XXCoder: not too bad
05:00 PM LeelooMinai: Yes, well, I am under no ilusion it will last as long as european ones, but I won't buy enphase one and then need $800 "gateway" of theirs and some silly monthly payment program to see the data, etc. :/
05:01 PM LeelooMinai: Bugger that
05:01 PM XXCoder: monthly fee?
05:01 PM XXCoder: geez
05:01 PM LeelooMinai: Right, I looked once at what is involved and it was absurd.
05:02 PM LeelooMinai: At least here I have simple RF + RS232 that can be hacked, REed, etc.
05:02 PM XXCoder: look at autodesk, buying everything and making them sub type
05:04 PM LeelooMinai: Right, they are monstroius company though. Their Fusion360 "division" does good things for hobbyists, so at least that's a plus there for me:)
05:04 PM LeelooMinai: If all their software was like that, it would be nice - non free only if you make some substantial money using it.
05:05 PM XXCoder: fustioon360 is part of autodesk? thought it wasnt
05:06 PM Tom_itx: yup
05:06 PM LeelooMinai: No, it's Autodesk, but you know, they have nice team of programmers, etc. which is a different world than marketing people:)
05:06 PM XXCoder: true that
05:06 PM Deejay: gn8
05:07 PM LeelooMinai: So, so far it seems to be doing the right things. I hope some marketing BSter will not decide to destroy it one day.
05:07 PM XXCoder: indeed
05:09 PM LeelooMinai: Hmm, I glued PVC parts meant for roofing to renew entrance door frame, etc. using epoxy - hope it was not dumb:)
05:10 PM LeelooMinai: I tried PVC cement and universal cement first, but this stuff requires perfect clamping and it was a bit of a fail...
05:11 PM Tom_itx: not sure epoxy will stick
05:11 PM LeelooMinai: So far epoxy seems to hold it together fine, but not sure what will happen when there's -30C:)
05:11 PM LeelooMinai: I sandpapered a bit surfaces and it does stick strongly, just not sure if temperature changes will have some effect or not. In theory epoxy is flexible, but who knows...
05:13 PM jym: LeelooMinai: It's not that as much as "compeating with china pricing mentaity" (aka wallyworld)
05:13 PM LeelooMinai: The what? :)
05:13 PM jym: LeelooMinai: People see something that's cool, but they want to pay the china import prices, not realizing something is hand made.
05:15 PM LeelooMinai: Right, but to be fair, I noticed here in Canada that richer people gladly pay extra for furniture, general home decoration/stuff that is hand made localy.
05:15 PM LeelooMinai: So, I guess depends what it is.
05:16 PM jym: LeelooMinai: Luminaries
05:17 PM LeelooMinai: jym: You are making using me google too much:p
05:17 PM jym: LeelooMinai: hang on...
05:18 PM jym: LeelooMinai: https://www.google.com/images?q=luminaries
05:19 PM LeelooMinai: Looks like something from cementary:)
05:19 PM LeelooMinai: Or cemetary
05:19 PM jym: http://finest10.com/wp-content/uploads/2016/10/make-dandelion-paper-lanterns-apieceofrainbowblog-2.jpg
05:19 PM LeelooMinai: cemetery? Damn, I think I mixed it with cement:)
05:19 PM jym: lol
05:20 PM jym: LeelooMinai: there are also these type http://www.dhresource.com/0x0s/f2-albu-g3-M00-FA-23-rBVaHVZEMISAN3z3AAZ2ObGJzOA682.jpg/japanese-style-wooden-desk-lamp-bedroom-decorative.jpg
05:20 PM LeelooMinai: jym: Well, those can be easily made with CNC cutter or something - kind of tough to fight cheap ones I guess.
05:21 PM LeelooMinai: What do people use them for even...
05:22 PM jym: LeelooMinai: whatever, accent lighting, table lighting, patio, etc
05:22 PM LeelooMinai: A, ok, right... My sister would like it - she is not like me:)
05:23 PM jym: LeelooMinai: she has short nails you mean?
05:23 PM LeelooMinai: I would take it, disassemble, use the wooden round sticks for glue, etc. and cut the cable for some other project:)
05:24 PM jym: LeelooMinai: Has anyoen told you you are a PITA?
05:24 PM jym: Loveable pita, but a pita ;)
05:25 PM LeelooMinai: Well, I sit in my room so, not much in a way of people I guess...
05:26 PM jym: LeelooMinai: Eh, that's okey I guess, but also means you miss out on good people too.
05:27 PM LeelooMinai: Hmm, starting season 7 of robot wars. The quality went up from 480 to pseudo 720 - yay:(
05:27 PM XXCoder: person in interest for troll action?
05:29 PM XXCoder: (PITA)
05:29 PM jym: LeelooMinai: CNC? We don't need no stickin CNC, we got laser!!! http://i.imgur.com/CaAG9jB.jpg?2
05:29 PM jym: XXCoder: PITA = Pain In The Ass
05:29 PM XXCoder: jym: I know. :P
05:30 PM LeelooMinai: jym: Some CO2 contraption?
05:30 PM jym: LeelooMinai: huh?
05:30 PM LeelooMinai: The laser
05:30 PM jym: LeelooMinai: Yes, ULS M-300
05:31 PM BeachBumPete: jym is that your machine?
05:33 PM LeelooMinai: jym: They say they have automatic fire detection/extinguishing feature - I guess that's good:)
05:34 PM jym: LeelooMinai: Yeah, a $30K machine destroayed in less than 90 seconds is not a good thing.
05:35 PM LeelooMinai: Hmm, wonder if buying just a compact laser head like that and electronics and attaching it to a CNC would work well.
05:36 PM XXCoder: too low wattage
05:36 PM LeelooMinai: Could be a cheap option...
05:36 PM Loetmichel: LeelooMinai_ depends on the wattage of the laser
05:36 PM XXCoder: LeelooMinai: theres tons on aliexpress lol
05:36 PM Loetmichel: you can cut thin wood and plastics with a 2W UV laser
05:36 PM Loetmichel: not more
05:36 PM XXCoder: though you need 40w in least for some ability to cutm and 60w for better. theres higher like 120w
05:36 PM LeelooMinai: XXCoder: What wattage... I mean to a CNC platform like I have: since all the expensive axis/frame stuff is there.
05:37 PM XXCoder: ahh diodes you can get 10w max
05:37 PM Loetmichel: XXCoder: not true
05:37 PM XXCoder: buy cheap frame one and buy upgrade from say 1w to 10w
05:37 PM LeelooMinai: XXCoder: I mean those: https://www.ulsinc.com/discover-uls-innovations/uls-laser-sources
05:37 PM Loetmichel: there are IR laser diode arrays with 100W and more
05:37 PM Loetmichel: the beam quality isnt really a concern for laser cutting
05:37 PM XXCoder: im sure price to match also
05:37 PM Loetmichel: yes
05:37 PM Loetmichel: they are pricey
05:38 PM LeelooMinai: They are CO2 sources as I understand in a compact form... Unless I read wrong.
05:38 PM Loetmichel: but not in the range of "professional" laser cutters
05:38 PM XXCoder: up to 500w
05:38 PM Loetmichel: LeelooMinai: co2 laser tubes have to have certain length per watt
05:38 PM XXCoder: I wonder if thats high enough to cut thin metal lol
05:38 PM Loetmichel: so they get a bit "unwieldy" soon
05:39 PM LeelooMinai: Right, that CO2 tech bothers me. Diode ones seem more attractive to me.
05:39 PM Loetmichel: XXCoder: the 80W co2 tube of a friend could cut .2mm steel
05:39 PM XXCoder: too bad co2 tubes cannot be bent
05:39 PM Loetmichel: 0.3mm stainless: no penetration
05:39 PM LeelooMinai: Too bad that CO2 tubes are Co2 tubes:)
05:40 PM LeelooMinai: Too many things that can go wrong imo and they deteriorate with time I think.
05:40 PM sync: there is nothing wrong about them
05:40 PM sync: they are cheap
05:40 PM sync: buy a similar fiber laser
05:40 PM jym: LeelooMinai: She had been runng the same job all day long multiple times. Went to the front door to sign for a package. This is what she returned to... http://i.imgur.com/3XLHedY.jpg
05:40 PM LeelooMinai: They are like electronic tubes vs transistors to me:)
05:41 PM LeelooMinai: Well, or diodes... since laser diodes.
05:41 PM sync: a fiber laser has diodes
05:41 PM LeelooMinai: jym: I remember that one:)
05:42 PM LeelooMinai: I also remember that water damage done by fire fighters was the most cost for renovation...
05:43 PM LeelooMinai: So, the moral of the story is not to call them unless you are sure your whole house will be gone.
05:43 PM LeelooMinai: Also, have fire extinguisher.
05:43 PM LeelooMinai: They probably should include them with those laser cutters by default:)
05:44 PM jym: CO@ extenguisher, poweeder is caustic
05:44 PM XXCoder: HALON ;)
05:44 PM XXCoder: just dont be trapped in room with it
05:44 PM jym: XXCoder: internationally banned except on plane and boat
05:44 PM XXCoder: can be licensed actually but very expensive
05:45 PM jym: XXCoder: Into no longer made, only recycled/resold
05:45 PM LeelooMinai: Some fires can be extinguioshed by shockwave of an explosion... Just saying:)
05:46 PM XXCoder: what do they use now if theres certain fires that cannot be put out by normal water system (no, explosions dont count lol)
05:46 PM sync: argon/co2 mixes
05:47 PM jym: XXCoder: FE-13
05:48 PM XXCoder: https://youtu.be/5hG4T7GJXH8 insane
05:49 PM LeelooMinai: XXCoder: Hm?
05:49 PM XXCoder: keep watching
05:49 PM LeelooMinai: O, lol...
05:49 PM LeelooMinai: I guess did not see that coming...
05:51 PM sync: old news
05:51 PM XXCoder: yeah apparently they dont care about those stores, but also if hit something too bad
05:52 PM XXCoder: they give fair warning, assuming everyone is hearing lol
05:53 PM LeelooMinai: High Risk Marketing
05:53 PM XXCoder: extra high for deaf people
05:53 PM XXCoder: though its olvious when people is prepping for train
05:53 PM LeelooMinai: Deaf people just have to hold one bare foot on the rail.
05:55 PM XXCoder: I suppose lol but requires bare foot :P
05:55 PM LeelooMinai: If I was a teenager living there, I would bou one of those gas-can powered horns and troll everyone.
06:02 PM jym: LeelooMinai: Just one more year to go, then you will be!
06:03 PM roycroft: so much for cooling off today and only getting up to 31
06:03 PM roycroft: it's 35 outside right now, with a couple more hours of warming to go
06:03 PM XXCoder: 35f? dang thats cold
06:04 PM jym: XXCoder: Yep
06:05 PM roycroft: i just came in from spending 4 hours out in the heat working on my yard and garden
06:05 PM roycroft: it was not fun
06:05 PM roycroft: it looks nice though :)
06:06 PM XXCoder: you must be one of those ice zombies if 35f is hot to you ;)
06:06 PM roycroft: i don't know why you would assume that i use an antiquated, stupid temperature scale
06:08 PM XXCoder: heh I always deberately choose wrong units when people leave that out :)
06:10 PM roycroft: c is the default temperature unit
06:10 PM roycroft: i'll specify f if i ever use that
06:10 PM XXCoder: f is default temperate unit
06:10 PM XXCoder: it depends on where. thats why i always specify units
06:12 PM JT-Shop: 10" ring hand formed from 1/8" x 1" steel is done
06:12 PM roycroft: fahrenheit is only used in th us, the cayman islands, micronesia, belize, and the bahamas
06:12 PM roycroft: the entire rest of the world use celcius
06:12 PM roycroft: therefore it is the default
06:12 PM XXCoder: nah. default depends on where person saying it lives in
06:12 PM XXCoder: thats why I always use units
06:14 PM roycroft: in science, degrees celcius are referred to as "degrees", whereas degrees fahrenheit are referred to as "degrees fahrenheit", and degrees kelvin as "degres kelvin"
06:15 PM XXCoder: Now, SI is different
06:15 PM XXCoder: I wouldnt be using F when discussing science
06:16 PM roycroft: you're just being obstinate and argumentive
06:16 PM XXCoder: nah im just telling you that people dont always agree on what units to use, outside science
06:16 PM XXCoder: thats why I always say what units. that is literally all.
06:16 PM DaViruz: there is no such thing as degrees kelvin
06:17 PM roycroft: you knew exactly what i meant, yet you chose to argue
06:17 PM roycroft: that is what is called "being argumentive"
06:17 PM XXCoder: not precisely actually
06:17 PM * JT-Shop goes to play with the chickens...
06:17 PM XXCoder: you might live at country thats cold in june-july
06:18 PM hazzy1: I have a degree in Nuclear Engineering and we never once used Centigrade, only Fahrenheit, which I find very interesting since Nuclear engineering seems so close the Chemistry where it is almost unheard of to use Fahrenheit.
06:18 PM roycroft: you're correct, daviruz
06:18 PM roycroft: kelvin is the complete unit
06:19 PM roycroft: 273.16 kelvin is 0 degrees
06:19 PM XXCoder: k is bit annoying as there is k and K and I keep forgetting which is zero at water freeze and which is zero when literally no heat
06:19 PM roycroft: which is 32 degrees fahrenheit
06:19 PM hazzy1: I am in the US though, and most nuclear folks are old fogies :)
06:20 PM roycroft: your discipline needs reform, hazzy1 :)
06:20 PM hazzy1: You may are probably right!!
06:21 PM hazzy1: And we use slugs for mass too :D
06:21 PM XXCoder: indeed. honestly I hate imperial system
06:21 PM roycroft: and bananas as a unit of radiation
06:21 PM roycroft: :)
06:21 PM XXCoder: I prefer SI but grew up on imperial so sometimes conversions is harder
06:22 PM roycroft: you grew up in the uk?
06:22 PM XXCoder: roycroft: you ever seen xkcd radition chart?
06:22 PM roycroft: yes, i have
06:22 PM DaViruz: i think the defining temperatures for farenheit is a bit too arbitrary
06:22 PM XXCoder: roycroft: imperial system is usa system, foot, inches so on
06:22 PM hazzy1: Units are so much a matter of what one is used to
06:22 PM roycroft: i understand how/why the scale came about
06:22 PM roycroft: but it's still dumb
06:22 PM XXCoder: I love that xkcd chart, shows ratio of radioactivity
06:23 PM roycroft: 0 degrees f is about the coldest temperature one would experience in a temperate climate
06:23 PM roycroft: and 100 degrees f is about the hottest
06:23 PM hazzy1: That rad chart is great, and quite accurate
06:23 PM roycroft: it's a temperature scale that was created so that humans could relate to it
06:23 PM XXCoder: only 100f? hottest I have experenced is 117f
06:23 PM roycroft: but it's totally arbitrary
06:23 PM XXCoder: and dead valley 120f or so
06:23 PM roycroft: and people do not generally hang out in death valley
06:24 PM XXCoder: Austulia recently experenced 50c
06:24 PM roycroft: daniel fahrenheit was dutch
06:24 PM XXCoder: theres people who live there
06:24 PM XXCoder: nearby town anyway if I recall, which experences near same temperate
06:24 PM hazzy1: I have a 500 mCi Po source sitting on the table beside me, exposure is about like being on an airline flight
06:27 PM roycroft: i have an oil lamp whose base is colored with uranium dioxide
06:27 PM XXCoder: fancy
06:29 PM hazzy1: Transparent green? or orange?
06:29 PM roycroft: it's a yellowish white
06:30 PM roycroft: uranium dioxide was commonly used as a yellow glaze until babout 1960, when it became scary all of a sudden
06:30 PM roycroft: about
06:30 PM hazzy1: hmm, I did not know that
06:30 PM XXCoder: isnt that pretty toxic?
06:31 PM hazzy1: No its encapsulated so well
06:31 PM XXCoder: cool
06:31 PM hazzy1: Vitrification is one of the best ways to treat rad waste so it does not leach into ground water etc
06:32 PM XXCoder: hazzy I read about interesting reactor that could run on nuclear waste from normal ones
06:32 PM hazzy1: We have quite a collection of radioactive dishes in the lab to show visitors
06:32 PM XXCoder: using up to 98% of ponental energy in it, so its radioactive for only couple hundred years
06:32 PM roycroft: it glows nicely under a black light
06:33 PM roycroft: a geiger counter would probably be mildly interested in it
06:33 PM hazzy1: roycroft: Yes, goes off the scale!
06:33 PM XXCoder: haz yeah saw pic of bowl and plate. wow. guy keeps it in lead bucket and lid to contain it when its not in leaded glass enclosure display
06:33 PM sync: pfft
06:33 PM roycroft: but i do not feel a warm glow from it
06:33 PM roycroft: unless i have the lamp lit
06:34 PM sync: I also have some uranium glass and plates
06:34 PM roycroft: when the radioactive mantle glows :)
06:34 PM sync: sometimes they come into rotation when everything else is dirty
06:34 PM hazzy1: There is no need to store it that way, you could eat from those dishes no problems and many generations have!
06:34 PM sync: yeah
06:34 PM sync: if you do that you better store your bananas in a lead bucket as well
06:35 PM hazzy1: lol
06:35 PM roycroft: my mantles are made of thorium dioxide
06:35 PM XXCoder: haz theres some laws about public display so he has to do that
06:35 PM XXCoder: since it is display stuff
06:35 PM XXCoder: he also managed to get depeted uranium fuel rod
06:36 PM hazzy1: Very nice!
06:36 PM hazzy1: I have some 20% U ore
06:36 PM XXCoder: I'd love to collect elements samples but whatever
06:36 PM DaViruz: depleted uranium possibly, depleted uranium fuel hardly
06:36 PM DaViruz: that stuff is seriously radioactive
06:37 PM XXCoder: i do have just a few. it's amazing how big difference between ti and tungstein are
06:37 PM XXCoder: both shaped to same shape so density
06:37 PM DaViruz: and will be for a long time
06:37 PM XXCoder: DaViruz: youre correct im sure
06:38 PM roycroft: i'd be more worried about having a sample of pure sodium laying around than some uranium
06:38 PM jym: XXCoder: Just mix H+O2+C3+PO
06:38 PM hazzy1: I know somebody that has several lbm of used uranium fuel rods from CP1
06:39 PM hazzy1: roycroft: for sure
06:40 PM DaViruz: since xkcd was brought up: https://what-if.xkcd.com/imgs/a/29/pool_danger.png
06:40 PM DaViruz: :)
06:40 PM XXCoder: some minerial oil container would work I would think
06:40 PM XXCoder: or some kind of oil sodium dont react to
06:40 PM DaViruz: (re spent reactor fuel)
06:40 PM * jym dumps 50,000 used and broken smoke alarms on to XXCoder
06:41 PM XXCoder: :P im not radioactive scout thank you very much
06:41 PM jym: you are now
06:41 PM pink_vampire: what is the smallest sand blast box?
06:42 PM jym: pink_vampire: your hand
06:44 PM hazzy1: One of the managers at Westinghouse Nuclear told me that he fell into the reactor vessel once. There must not have been many leakers in that core as he was contaminated only a little. Very lucky fellow
06:46 PM hazzy1: They had divers welding up some eroded nozzles and he was trying to watch them and leaned out too far, oops!
06:47 PM XXCoder: ouch good thing guys ok
06:56 PM hazzy1: Here is a pic i took of the reactor vessel at the Westinghouse Nuclear training site: http://i.imgur.com/XscHs23.jpg
06:57 PM XXCoder: hazzy1: I remember reading about using blue light and retrorefective surfaces to fake that blue radioactive glow
06:58 PM hazzy1: Yes, there is not fuel in that pool, it is for training
06:58 PM XXCoder: yeah I guessed that
06:59 PM XXCoder: I was just off to fake radiactive glow prank tangent lol
06:59 PM hazzy1: I would get in trouble if I posted a pic of actual core :D
06:59 PM XXCoder: found it
07:00 PM XXCoder: http://amasci.com/hoax.html look at radioactive nightmare section a little bit down
07:03 PM hazzy1: It is actually safe to be on the bridge of a fueled reactor because there is about 20ft of water which is one of the best shealding materials, for neutrons
07:03 PM hazzy1: The Cerenkov radiation is beautiful!
07:03 PM XXCoder: never had oppounity to see that and doubt I will lol
07:04 PM XXCoder: im mere machinist not radioactive techinican or whatever! lol
07:07 PM roycroft: where are the nuclear wessels? i want to safely stand on one1
07:07 PM roycroft: !
07:07 PM XXCoder: lol
07:07 PM XXCoder: ... and it is Enterprise.
07:09 PM XXCoder: that one is little campy movie but good

07:58 PM hazzy1: roycroft: there are 4 large nuclear reactors here in Georgia, and 2 more under construction. There is also at least one research reactors in the area that will allow the general public to come and look directly at the core while it is in operation. The large plants will allow visitors into the containment during refueling outages for educational purposes, and if you asked the right person very nicely they might allow you onto the refu
07:59 PM XXCoder: tht article should specify faster than light speed in water media
08:00 PM hazzy1: I was the vice president of the Kennesaw State University Nuclear Society and have set up several such tours. :)
08:03 PM hazzy1: XXCoder: When I was first told that Bremstralung radiation was do to particles going faster than light I did not believe it possible, faster than light in water is the key!
08:03 PM XXCoder: indeed
08:07 PM pink_vampire: I want sand blasting!
08:07 PM pink_vampire: why thee box is sooo large
08:10 PM hazzy1: pink_vampire: If the box is too small it is very hard to work in and the sand cloud makes it hard to see what is going on
08:11 PM XXCoder: theres usually a lot of sandblster box opn sale at criaglist or something
08:11 PM pink_vampire: i need something for very small parts
08:11 PM hazzy1: I have this blast cabinet and it is almost to small even for things like small casters: https://www.harborfreight.com/benchtop-blast-cabinet-62454.html

08:12 PM hazzy1: Have you seen the sand blasters for cleaning spark plugs? Maybe somthing like that would work for you
08:14 PM pink_vampire: http://embeddedjunkie.com/tag/paasche/
08:14 PM hazzy1: For rely small parts that are hard to hold I have punched a hole into a 1 quart plastic bin, thrown the parts in ans then stick the gun thru the hole and blast away. It is more like tumbling the parts but works OK
08:16 PM LeelooMinai: Hmm... so what happens if those gloves break? I somehow imagine a guy running around with a pair of bloody extremities, but that's probably not likely? :)
08:17 PM XXCoder: ypu don't want to inject sand and air in hands.
08:17 PM XXCoder: emolism is one of possibilities

08:23 PM pink_vampire: I found a new hobby?!?
08:23 PM jdh: cleaning fossils?
08:23 PM pink_vampire: I think it's cool
08:24 PM jdh: http://imgur.com/psFhDYx
08:25 PM jdh: cleaning them is boring.
08:25 PM pink_vampire: shark teeth ?
08:25 PM jdh: yeah, mostly megaladon
08:25 PM jdh: http://i.imgur.com/XN4KyLJ.jpg cleaned
08:26 PM hazzy1: I drool over this every time I go to my Horror Fright store, it is very nicely made for being HF, but I have not found an legitimate need for it.
08:26 PM hazzy1: https://www.harborfreight.com/air-eraseretching-kit-69277.html
08:26 PM hazzy1: Thats a big tooth!
08:27 PM jdh: one of my better finds
08:39 PM hazzy1: This is my best find, big but ugly. A horse kicked it up: http://i.imgur.com/uLX7wf7.jpg
08:39 PM hazzy1: I have a 5 gal pail full of trilobite fossils. they are tiny ones and a pain to clean up, maybe I can get that air eraser after all...
08:40 PM malcom2073: Wonder if soda lime in that little spray gun would do good?
08:40 PM malcom2073: I've heard soda lime is really gently
08:40 PM malcom2073: in comparison to sand
08:41 PM pink_vampire: I want it to make an even finish to the parts
08:42 PM roycroft: if they're small parts, get a vibratory tumbler
08:42 PM hazzy1: Soda would need to be well graded so as not to clog the very small orifice. Maybe baking soda would be OK?
08:42 PM roycroft: it works ok
08:43 PM roycroft: you have to keep it really dry - it clumps up easily
08:45 PM hazzy1: hmm, I had not thought of clumping being a problem. here in the humid south that would likely make it almost impossible to recycle
08:50 PM roycroft: yes, i should think so
08:50 PM roycroft: unless you bake it between uses
08:52 PM hazzy1: I would also probably need to get a better line dryer on my compressor!
08:52 PM hazzy1: You all might be interested in this, a solid tungsten radiation collimator I made at the end of last year for imaging waste storage tanks at the Hanford Site in Washington: http://i.imgur.com/QQOsMLM.jpg
08:52 PM XXCoder: dry air coming out of compressor
08:52 PM XXCoder: and intake if possible
08:53 PM cradek: I have no idea what that means, but it's pretty
08:53 PM XXCoder: running air though air conditioner might dry air well enough so its not spitting water
08:55 PM pink_vampire: hazzy1: how did you machine solid tungsten?
08:55 PM hazzy1: cradek: It is basically a pinhole camera, but for radiation not visible light. Dirt simple but works great
08:56 PM XXCoder: hazzy1: tungsein is more resistant to radition damage or what?
08:56 PM XXCoder: or in least sheilding tech inside it?
08:57 PM hazzy1: Very slowly and with standard carbide, it works, but takes more than one tool :)
08:57 PM XXCoder: you ever seen video using cermeric tools?
08:57 PM XXCoder: wow
08:58 PM pink_vampire: ceramic inserts is crazy stuff
08:58 PM XXCoder: it cuts so hard that inocel metal chips are glowing pretty bright on seperation
08:58 PM hazzy1: Tungsten is dense and therefore blokes the radiation better
08:59 PM hazzy1: I have a G0602 lathe, too light to try ceramic tools I think, but boy I would like to!
08:59 PM XXCoder: https://www.youtube.com/watch?v=c1K5QjR3hyU
08:59 PM XXCoder: coolant would literally weaken and explode cermtic tool
09:00 PM XXCoder: lathe https://www.youtube.com/watch?v=BU14tfjUfQU
09:01 PM hazzy1: Hey, XXCoder next to that vid is one of Hoss using a G0602 with a ceramic tool: XXCoder:
09:01 PM XXCoder: ya second link lol
09:01 PM hazzy1: Oh you saw that too!
09:01 PM hazzy1: I should try that then!
09:01 PM XXCoder: pretty amazing eh, normally see just chips fly off
09:02 PM XXCoder: talking about weird tooling https://www.youtube.com/watch?v=jxWbz0Wf2rM
09:02 PM XXCoder: diamond turning
09:03 PM pink_vampire: and very good cooling
09:03 PM XXCoder: the cermtic ones? no it cannot be cooled
09:03 PM hazzy1: I guess acrylic is abrasive enough to make using diamond worth while?
09:03 PM XXCoder: haz good question
09:04 PM hazzy1: Boy, that is a good surface finish!
09:04 PM XXCoder: yeah
09:10 PM XXCoder: wow. https://www.youtube.com/watch?v=0rMLxb3hknI
09:16 PM hazzy1: They have a string and washer? hanging from the ceiling to tell when it is the right hight. Genius!
09:19 PM malcom2073: XXCoder: That's awesome
09:20 PM LeelooMinai: I wonder why they hid when it was growing:p
09:21 PM hazzy1: I am surprised the acrylic stays hot for that long, it must be pretty thick.
09:21 PM hazzy1: When vacuuming forming in the past I have had problems with it cooling off so fast I could hardly even position it brfore it was too cold to pull
09:22 PM malcom2073: Man it looked fabric-y when they pulled it out
09:22 PM malcom2073: Maybe they use hot air?
09:22 PM malcom2073: Think that'd help?
09:24 PM hazzy1: That could be. Also I guess when vacuum forming the sheet is in contact with the mold so there is better thermal conduction then if just the air
09:25 PM hazzy1: Does look like they but down a preheated base sheet, which probably helped too
09:26 PM malcom2073: Ah yeah true, I saw that
09:26 PM malcom2073: Ohh
09:26 PM malcom2073: that white thing they put under
09:26 PM malcom2073: they're passing the air through it, and it's hot
09:26 PM malcom2073: So it is heating the air
09:28 PM hazzy1: Yeah, your right!
09:28 PM hazzy1: Must be a heated sandbag
09:28 PM hazzy1: Clever!
09:30 PM malcom2073: Real slick
11:02 PM hazzy1: Oops, I am working on my LCNC interface and just managed to cause a recursion of recursion errors!
11:02 PM hazzy1: I did not know that was even possible...
11:09 PM roycroft: kind of a "chain reaction", eh?
11:14 PM hazzy1: Yep! I wanted hitting escape on the physical keyboard to close the virtual keyboard. Simple I thought, just connect the physical keyboard even to the virtual keyboard event. BUT the virtual keyboard event simulates a physical keyboard event. BOOOOOOM
11:14 PM hazzy1: It must be time for bed....
11:14 PM roycroft: just what we want to hear from a nuclear engineer
11:15 PM roycroft: when the uncontrollable chain reaction starts, it's time for bed
11:15 PM hazzy1: Good one! Im rolling on the floor!!
11:16 PM LeelooMinai: Well, if it's uncontrollable, what's the point of doing anything - you can as well go to bed, why not:)
11:16 PM hazzy1: Thats my reasoning!
