12:02 AM roycroft: i'm taking my auto-darkening welding helmet with me
12:04 AM MarcelineVQ: better set it to sensitive :>
12:04 AM roycroft: since a tungsten arc is brighter than the sun, it should work brilliantly
12:04 AM roycroft: i think i'm supposed to set it to 14 for staring at the sun
12:04 AM XXCoder: you can take emergacy blanket and cut 2 layer squares out of it, and use cardboard as frame
12:04 AM MarcelineVQ: not the shade, the sensitivity, or it won't turn on
12:04 AM XXCoder: I used one to watch venus crossing
12:04 AM roycroft: it turns on when i turn my head towards the sun
12:04 AM roycroft: so i'm not concerned about that
12:04 AM MarcelineVQ: a non-elicsed sun
12:04 AM hazzy: I can't find the proper shades so I think I will use my welding helmet, but, is it save? I mean does it block the right spectrum?
12:04 AM roycroft: it's usually annoying
12:04 AM MarcelineVQ: *eclipsed
12:04 AM HighInBC: when staring at the eclipse remember to only use one eye so that you can use your other eye to see the rest of your life
12:04 AM roycroft: it is, hazzy
12:04 AM roycroft: i've done a bit of research, and a good welding helmet is perfectly safe
12:04 AM hazzy: Ok, that is good to know
12:05 AM roycroft: unlike all those counterfeit "eclipse glasses" that are floating about
12:05 AM roycroft: which is one reason i'm using my welding helmet
12:05 AM roycroft: i *know* it's safe
12:08 AM hazzy: I know in the old days they used the bottom of a beer bottle, cant be worse than that!
12:08 AM roycroft: random glasses i'm not sure about
12:08 AM roycroft: you can always use a cardboard box with a pinhole
12:08 AM roycroft: it won't really matter if you watch the eclipse upside down
12:08 AM MarcelineVQ: shade 14 glass in a helmet is perfectly safe, 10+ can be fine depending on your own eyes. 14 is pretty conservative, I think I only use 12 for hot arcs and those are far stronger than the sun
12:08 AM hazzy: I have a projector I built for the Venus transit so I will set that up too
12:08 AM roycroft: i use 13 for gtaw welding
12:08 AM XXCoder: can always make camera obscura
12:08 AM XXCoder: its very simple to make
12:08 AM MarcelineVQ: reasonable, gtaw with a shielding gas is super bright since there's nothing obscuring the arc
12:08 AM HighInBC: I don't look at the sun during an eclipse, I watch the area around me get dark. The actual eclipse is best seen on video
12:08 AM * HighInBC ducks
12:08 AM roycroft: i'm not planning on staring at the sun the entire time
12:08 AM MarcelineVQ: idk why I specified shielding gas, gtaw is obviously gas shielded ehe
12:08 AM hazzy: My projector uses a wide angle telescope and rear projection screen, it gives excellent resolution of sun spots etc
12:08 AM roycroft: watching the rapid change in light quality on the ground will be more interesting, except during totality
12:08 AM roycroft: i plan on staring directly at the sun for a good 2+ minutes then
12:08 AM XXCoder: well done eyes is yummy
12:08 AM roycroft: well
12:08 AM roycroft: at the moon :)
12:08 AM hazzy: :D
12:09 AM roycroft: the corona is only 1 millionth as bright as the sun
12:09 AM roycroft: it's safe to view with the naked eye
12:11 AM MarcelineVQ: that's a bit of a gambling sentence :> there's really no perfect eclipse that only exposes a corona, and if there were it's only for the brief moment when things are aligned
12:12 AM XXCoder: yeah, even when its aligned so it dont look like diamond ring, I would look directly for less than a second
12:12 AM roycroft: actually, the moon is fairly close to earth right now, and will more than cover the sun
12:12 AM roycroft: which is why totality will last for over 2 minutes
12:12 AM XXCoder: being deaf, my eyes is very precious to me thankj you very much
12:13 AM roycroft: sure
12:13 AM roycroft: but it is perfectly safe
12:13 AM roycroft: we have this thing called "science" that helps us sort these things out
12:13 AM * XXCoder eyerolls
12:13 AM roycroft: and mean real science
12:13 AM roycroft: not fake science
12:14 AM XXCoder: theres real science then theres real paraoria
12:14 AM XXCoder: theres real science then theres real paranoia
12:14 AM roycroft: and real science says that it's perfectly safe to watch during totality with the naked eye, and that totality will oast > 2 minutes
12:14 AM roycroft: almost 3 minutes in some parts of the country
12:15 AM roycroft: missouri/illinois/kentucky will have the longest period of totality
12:16 AM roycroft: there have been eclipses with over 6 minutes of totality, when the moon is really close (relatively) to the earth
12:20 AM XXCoder: anyway I do know at proper stage it is safe to look
12:20 AM XXCoder: I'm just very paranoid about losing sight
12:20 AM roycroft: i shouldn't be paranoid about it
12:20 AM roycroft: concerned, perhaps
12:21 AM XXCoder: I have only 3 "main" senses lol
12:21 AM roycroft: i can hear fine, but i still would really really not want to do anything that might jeopardize my vision
12:23 AM Gene_home: just had retina surgury... recovering still... I will not be looking at the sun
12:24 AM hazzy: Working on drag n drop widget layout for LinuxCNC UI: https://youtu.be/UH46HOeBGuc
12:24 AM hazzy: A little progress ...
12:26 AM Gene_home: hazzy: ok... can you provide an overview?
12:27 AM hazzy: The idea is to have a "library" or UI widgets (DRO, Backplot ...)
12:27 AM Gene_home: ok
12:27 AM hazzy: and then be able to drag them from a menu and position then where needed and when needed
12:30 AM hazzy: Calling it a day here
12:30 AM hazzy: gn8
12:31 AM Gene_home: cool!
12:34 AM roycroft: during totality one is not looking at the sun
12:34 AM roycroft: one is looking at the sun's corona and at the moon
12:37 AM HighInBC: one wails in terror at the end of the world
12:37 AM HighInBC: then feels foolish an hour later
12:37 AM roycroft: this is why 99.7% isn't good enough :)
12:37 AM HighInBC: it will be on youtube
12:38 AM roycroft: which will be nothing like experiencing it in person
12:38 AM HighInBC: which is nothing compared to sitting on the moon watching the shadow move across the Earth
12:38 AM HighInBC: that is what REAL eclipse watchers do
12:38 AM roycroft: that would be interesting too
12:39 AM HighInBC: If I was in the area, I would like to measure the angle between two known stars on either side of the sun
12:39 AM HighInBC: to reconfirm gravity effects light
12:39 AM HighInBC: just in case it has changed
12:40 AM roycroft: i don't really have the means to do that, but it would be interesting
12:40 AM roycroft: a lot of people will be doing exactly that though
12:40 AM roycroft: real scientists
12:40 AM roycroft: and maybe even some fake scientists :)
12:40 AM HighInBC: well, hobbiests I would think, considering how extensively this experiment has already been repeated and the underlying principals proven other ways
12:41 AM HighInBC: and people who just don't believe others
12:41 AM roycroft: some believe the earth is flat
12:41 AM roycroft: soem believe that the sun orbits the earth
12:42 AM HighInBC: some do, but 90% of people who say that just like to argue
12:42 AM HighInBC: it is a ready excuse to argue with someone
12:42 AM MrTrick: anyone know how to use a box brake?
12:42 AM HighInBC: every time I use GPS I remind myself that the clocks on those satellites run at a different speed to compensate for the time warp between us and them
12:42 AM MrTrick: I'm stuck, can't figure out how to do the first bend; https://i.imgur.com/YMEyJuo.png
12:42 AM roycroft: adjust fingers
12:42 AM roycroft: insert metal
12:42 AM roycroft: pull handle
12:42 AM roycroft: repeat until finished
12:42 AM MrTrick: okay, see above - the vertical-ish bend with the flap
12:43 AM MrTrick: the part underneath is meant to stay flat
12:43 AM roycroft: right
12:43 AM roycroft: you remove one of the fingers so you have clearance
12:43 AM roycroft: one or more
12:44 AM MrTrick: that will deform the flat part, or tear it, no?
12:45 AM roycroft: it might deform it slightly
12:45 AM roycroft: since it will still get pushed into the lower channel somewhat
12:46 AM MrTrick: right, so that seems not ideal.
12:47 AM roycroft: i don't know how large the part is, but you could make a little brake to fit in a bench vise for bending that part, and leave the flat part totally outside the vise jaws
12:48 AM roycroft: your bend is a somewhat unusual one for a box brake
12:48 AM roycroft: so you might have to get creative
01:13 AM archivist: a water level proves the world is flat !
01:17 AM hazzy: How so? I used a water level to set a foundation and it did not end up flat, so it can't possibly prove the world is flat!
01:17 AM roycroft: you need to make the foundation out of water too
01:19 AM hazzy: Oh, is that the key
01:26 AM XXCoder: earth is flat, sometimes. thats why someone has to come in and blow it up to sphere again
01:27 AM XXCoder: flat earthers just saw it when it was flat
02:03 AM roycroft: flatness is relative
02:04 AM archivist: my CMM has a flatness problem
02:05 AM archivist: http://www.collection.archivist.info/searchv13.php?searchstr=brown+pd+level
02:06 AM archivist: I think the threaded plate is coming unglued from its mounting
02:22 AM Deejay: moin
06:09 AM JT-Shop: morning
08:09 AM gloops is now known as Goodlord
08:42 AM Tom_L: man i wish i could figure out what's going on with this config
08:43 AM Tom_L: had to revert the bit file back to GPIO on those 2 pins
09:26 AM JT-Shop: damn birds ate all my grass seed
09:31 AM Tom_L: was it left out?
09:43 AM phipli: JT-Shop: your birds, or wild birds?
09:45 AM * phipli gets fed up of flicking between windows and plugs in the TV as a second monitor
09:45 AM phipli: HDTV++
10:07 AM JT-Shop: I seeded the chicken lawn because there was no grass left and birds and neighbors chickens ate all the seeds
10:08 AM Tom_L: and they just thought you were being kind
10:18 AM JT-Shop: phi
10:18 AM JT-Shop: phipli: http://gnipsel.com/images/chickens-2/7-19-17.jpg
10:19 AM phipli: :)
10:41 AM JT-Shop: I've named one of the chicks Blondie
10:44 AM Tom_L: for color or demeanor?
10:44 AM HighInBC: nice chicks
10:45 AM HighInBC: chick pic
10:48 AM jthornton: her color, she is all blond with no black stripes
10:48 AM jthornton: dunno how long that name will stick as she turns red
10:49 AM phipli: :)
10:49 AM phipli: Have you named them all?
10:50 AM jthornton: no, there are only two I can tell apart lol
11:09 AM IchGucksLive: hi
11:10 AM Vq: Hallo
11:11 AM hazzy: IchGucksLive: Did you get the fire put out?
11:11 AM IchGucksLive: yes 9hr
11:11 AM IchGucksLive: but the farm is nearly asche
11:11 AM hazzy: That is to bad
11:12 AM IchGucksLive: lives has been saved
11:12 AM IchGucksLive: that is all that counts
11:12 AM Tom_L: how did that happen?
11:12 AM IchGucksLive: heu selfignight
11:13 AM IchGucksLive: so thew main thinking
11:13 AM Tom_L: electrical fire?
11:16 AM IchGucksLive: no ithas been raini during harvest so it might got wet during pressing
11:17 AM IchGucksLive: and this may cause a selfignight as head pures high during fermentation
11:22 AM phipli: IchGucksLive: sorry to hear you've had a fire
11:22 AM phipli: animals and people all got out?
11:25 AM IchGucksLive: no animals all people out
11:26 AM Vq: IchGucksLive: Many buildings?
11:26 AM IchGucksLive: 1 building about 500+ heu balls at 400kg eatch
11:29 AM jthornton: damn sorry about your fire
11:29 AM Vq: Wow, that must have burnt fiercely.
11:29 AM Vq: Sorry to hear it.
11:32 AM miss0r2: have any of you ever ordered something from china, and had it delievered with FLYT express? (I am wondering what local curriers they are using)
11:38 AM IchGucksLive: gloops: does the mashine run now on your command
11:41 AM IchGucksLive: ALL US SUN EClips Monday
11:41 AM IchGucksLive: go there it is a lifetime expiriance
11:41 AM IchGucksLive: you will be depth impressed and highly shockt about the 3 min event
11:42 AM IchGucksLive: 4mio people expecting to see it and on the way to the center path
11:42 AM IchGucksLive: so full traffic ahead
11:43 AM IchGucksLive: http://americaneclipseusa.com/see-the-2017-eclipse/travel/
11:45 AM IchGucksLive: so mondy the traffic jam is the biggest since freeway exists
11:46 AM tiwake: http://forums.extremeoverclocking.com/showthread.php?t=312178
11:48 AM IchGucksLive: tiwake: all you need is low latency ;-(
11:49 AM gloops: Ichs hi - yeah everything got pretty calm in the garage, things running more or less as should, not cutting yet, got spindle holder to fix up and a motor on the z
11:50 AM gloops: depending on free time, another week or 2
11:51 AM IchGucksLive: good to hear
11:52 AM tiwake: IchGucksLive: what?
11:52 AM gloops: probably need the scale tweaking, its ok at 200mm measurements, i guess probably better to take some measurements when it travels the whole axis
11:53 AM gloops: various bits of tweaking, at least i understand what affects what now - thanks
11:54 AM IchGucksLive: gloops: make a square within 20mm of axis xY and a 10mm smaller circle in it and let it run more then 5 times move back to zero and look to the offsets
11:54 AM IchGucksLive: at yoursetup only 4.steps per unit it might be good to go
11:55 AM IchGucksLive: a chain is not the best thing to move a small cnc
11:55 AM gloops: yeah will try that, i did have it set up to draw yesterday, got smooth circles (eventually ha ha) and nice square, but yeah i will do the circle in a square thats a good test
11:57 AM gloops: no load yet though - tbh i dont think backlash will be an issue, if i jog at .05 it reverses each way and moves, - not taking any slack up
11:57 AM IchGucksLive: you getring better on every change you make
11:58 AM gloops: yeah, i could drop to 1600 steps to give more resolution - ill just stay with 800 for now
12:00 PM IchGucksLive: im off for today garden work till darknes
12:01 PM tpra: hello
12:02 PM tpra: can someone tell me if the MESA 7i76E (ethernet) is supported by linuxcnc and if i understood correctly that it xould be enough on its own (no BoB) ?
12:22 PM Tom_L: it is a supported card
12:24 PM Tom_L: http://www.mesanet.com/pdf/parallel/7i76eman.pdf
12:25 PM Tom_L: isolated IO
12:25 PM Tom_L: looks like you may be good to go
12:28 PM tpra: ok, thanks :) sorry i'm new to cnc and don't really understand the mesa range.
12:29 PM tpra: but i tend to prefer an ethernet solution rather than 2 separate cards
02:12 PM JT-Shop: tpra: yes the 7i76E works with LinuxCNC
02:13 PM tpra: thanks to confirm, i just ordered one about 2 minutes ago :)
02:13 PM JT-Shop: you need to install LinuxCNC Uspace on a RTPreempt real time kernel
02:14 PM tpra: yes i've found a tutorial about that, hope i'll get it to work :) i'm used to 3D printing boards, but totally noob when it comes to cnc. i'll mount it on an OXcnc with leadshine drivers and stepper motors
02:14 PM JT-Shop: you should be fine
02:14 PM tpra: though i'm not new to linux (programmer for a living)
02:17 PM tpra: i still dunno if i need a triple edge finder, or if a simple plate would be enough
02:23 PM JT-Shop: to locate your material?
02:28 PM tpra: JT-Shop, mainly for tool height sensing, but i also may try to precisely cut wood assembly when i'll be more at ease, so yes a reliable way to find edges will be useful in the future
02:29 PM jdh: I like edges.
02:31 PM JT-Shop: tpra: you can use a dowel to find tool height in seconds
02:32 PM JT-Shop: I use a dowel in the spindle to fix the Y edge and use an edge finder to find the vise jaw for x
02:32 PM jdh: why not edge finder for Y also?
02:33 PM JT-Shop: https://www.youtube.com/watch?v=VmRUJk0ptN4
02:33 PM JT-Shop: takes too long
02:33 PM JT-Shop: I just slide the material up to the dowel that I've positioned 1/2 the diameter from where I want the edge of the blank
02:38 PM tpra: that looks simple :) i should perhaps stick to a diy touch sensor, as i don't need as much precision as needed for metal working (will be cutting foam, mainly)
02:40 PM phipli: tpra : http://www.ebay.co.uk/itm/192267025698
02:43 PM tpra: ho that's cheap :)
02:43 PM JT-Shop: phipli: got a coyote on my game camera last night
02:46 PM phipli: sniffing about?
02:47 PM JT-Shop: walking as if coming back from my coop and heading home
02:51 PM phipli: hum. what is the best way to discourage them?
02:53 PM tpra: JT-Shop, is the Stretch (uspace: realtime with RT-Preempt, and simulation) package ok for 7i76e usage ?
03:01 PM JT-Shop: phipli: you make them stop breathing
03:02 PM JT-Shop: tpra: yea but I forgot the link location
03:03 PM tpra: found a detailed step by step here http://linuxcnc.org/docs/2.7/html/getting-started/getting-linuxcnc.html
03:04 PM tpra: just some things to adapt for stretch but that's perfect :)
03:05 PM JT-Shop: there is a stretch iso somewhere
03:05 PM JT-Shop: hmm where is that
03:05 PM tpra: you mean an iso with preempt kernel and linuxcnc included ?
03:05 PM JT-Shop: http://linuxcnc.org/dists/stretch/
03:07 PM tpra: thanks
03:08 PM tiwake: the garage just got some shelving woo
03:24 PM pcw_home: There are some test Stretch + Preempt-RT kernel + linuxCNC ISOs here
03:24 PM pcw_home: http://www.linuxcnc.org/testing-stretch-rtpreempt/
03:26 PM tpra: nice :)
03:35 PM hazzy2 is now known as hazzy
03:35 PM rodweb: hi guys, is there a problem withour git respositry. Been a while since Iupdated
03:35 PM Tom_L: it moved if that's what the issue is
03:36 PM rodweb: using git.linuxcnc.org how do I update to the new address
03:36 PM JT-Shop: it's on github.com/linuxcnc
03:37 PM rodweb: yeh, thats the web. I'm at the command line thou
03:38 PM MarcelineVQ: https://help.github.com/articles/changing-a-remote-s-url/
03:38 PM rodweb: JT, in my workshop. This is spaceship Rod :)
03:38 PM MarcelineVQ: easier just to reclone though
03:38 PM JT-Shop: hey rod
03:38 PM MarcelineVQ: probably better to ask though, what problem are you having?
03:39 PM rodweb: I want to update Deweys external offset code
03:40 PM Tom_shop: git clone git://github.com/LinuxCNC/linuxcnc.git linuxcnc-dev
03:40 PM Tom_L: is what i did
03:40 PM rodweb: so how do I clone from the new repository?
03:40 PM Tom_L: ^^
03:40 PM Tom_L: afik
03:40 PM Tom_L: i'm no git wizzard
03:42 PM rodweb: Tom, fatal, linuxcnc-dev exists
03:42 PM Tom_L: well put it in a different directory
03:42 PM Tom_L: or just update
03:42 PM Tom_L: instead of clone
03:45 PM Tom_L: git pull ? maybe
03:45 PM tpra: pcw_home, i see the stretch rtpreempt images are considered experimental. would it be more reliable to install from scratch on wheezy ?
03:46 PM Deejay: gn8
03:53 PM rodweb: Tom, Maeceline, thanks changed te remote.Sun coming up, just heard the solar kick in
03:58 PM rodweb: tpra, I'd give the experimental build a go. Everything I'm using is experimental...
03:58 PM pcw_home: tpra: there may be some glitches but its a lot less trouble to install especially
03:58 PM pcw_home: if you have relatively new hardware and need a up-to-date kernel
03:59 PM JT-Shop: rodweb: good question about how to clone from github
03:59 PM rodweb: found MearcelineVQ's link did the trick, compiling...
03:59 PM JT-Shop: I think this only works for developers git@github.com:LinuxCNC/linuxcnc.git
04:00 PM rodweb: worked for me fine
04:01 PM tpra: my hardware will be a core i5 on asus motherboard, external ethernet card if needed. and a mesa 7i76e
04:01 PM rodweb: tpra, how old
04:02 PM tpra: about 4 or 5 years i think
04:02 PM tpra: it's an i5 4590, so 4th gen, we're at 7th gen now, so i assume, yes 5 years old rig
04:04 PM rodweb: I think I'd try the new ISO as a first step.
04:05 PM tpra: ok, not hard to try you're right
04:05 PM rodweb: JT - git remote set-url git://github.com/LinuxCNC/linuxcnc.git
04:05 PM JT-Shop: tpra: you don't need a high power motherboard and ethernet cards only work on the motherboard port
04:06 PM JT-Shop: Rod thanks
04:06 PM * JT-Shop should stop working on this PLC and fix the lawnmower tire
04:07 PM tpra: ok. so i could wire the mesa to motherboard ethernet port, and use the external card for lan. it's actually the oldest config i have around.
04:08 PM JT-Shop: exactly what I do
04:09 PM tpra: it was a pretty decent rig i trust, solid PSU, never any problem.
04:12 PM rodweb: tpra, give it a go. I expect it would work
04:12 PM tpra: i see in the documentation that an external graphics card gives better realtime results. i may have one too
04:12 PM tpra: somewhere ^^
04:12 PM rodweb: I don't think the 7i76e will care which interface
04:12 PM JT-Shop: not usually needed anymore
04:12 PM tpra: ok
04:13 PM rodweb: Sure it will be fine. I have 7i76e on a USFF
04:13 PM tpra: what is USFF ?
04:14 PM rodweb: ULtra small Form Factor 4" x 4"
04:14 PM tpra: ho ok
04:15 PM rodweb: If you get a fail, the next fallback would be the Mint howto on the forum
04:16 PM JT-Shop: crap can't communicate with the DL05 PLC
04:17 PM rodweb: can't help sorry JT
04:17 PM JT-Shop: no problem I just have to d/l the manual and see what I guessed wrong lol
04:21 PM rodweb: JT, sounds like you have too many hobbies. I used to too but now I have plasma machine....
04:21 PM rodweb: so no time for anything else...
04:22 PM JT-Shop: rodweb: it's work actually
04:23 PM rodweb: excused then. just compiled all my comps and good for THC test cuts. tpra, I was reminded you have to power your 7i76e on before starting LCNC.
04:24 PM rodweb: time for a cuppa tea and breakfast.
04:47 PM rodweb: JT, rolled back to a known good config, updated some settings for eoffsets and got halscope opening on start up so later in the morning I'll be back onto it.
04:52 PM JT-Shop: Rob I just figured out I need to upgrade to the next version of the programming software for $400 so I give up on $Day $Job work and fix the flat tire on the lawnmower
05:00 PM rodweb: don't you hate that. Had some following errors with my sneaky x2 setup. Seemed to be gone now. Forgot to up the STEPGEN_MAX settings
05:08 PM JT-Shop: hole was just small enough to let all the air out between mowings but not big enough to see easy
05:10 PM gloops: 2 motors 1 axis looks a real can of worms with emc2
05:11 PM JT-Shop: nope
05:12 PM phipli: hum
05:12 PM phipli: switched linux mint to mate desktop
05:12 PM gloops: how is it done then?
05:12 PM phipli: seems to have slightly improved the tearing I've never managed to get rid of
05:13 PM gloops: tearing?
05:13 PM phipli: when you play a video, there is a horizontal discontinuity
05:14 PM gloops: ahh ok
05:14 PM phipli: caused by the screen been re-drawn out of sync with the monitor refresh (usually)
05:14 PM gloops: i get that very bad with wine installs
05:14 PM phipli: It has been a problem for me on this laptop since I've had it
05:15 PM phipli: I think I fixed it once...
05:15 PM phipli: but then it started again after an update
05:21 PM phipli: brb
05:22 PM HighInBC: installing linuxcnc onto a VM right now. Have not got a CNC yet but I am sure I can still explore it a bit
05:25 PM gloops: you can get some idea with the simulation, it all becomes a lot clearer when hooked up to a machine though
05:26 PM HighInBC: simulator, nice
05:29 PM HighInBC: 3 hours of research has shown me that I need to do a lot more research before I buy a CNC
05:31 PM phipli: HighInBC: what sort of stuff do you want it for?
05:34 PM phipli: JT-Shop: when is your eclipse?
05:42 PM HighInBC: phipli: I want to do pcb routing, but I also want to be able to cut nice holes in project boxes
05:46 PM JT-Shop: phipli: dunno I don't follow that stuff
05:46 PM JT-Shop: cutting holes in boxes is a PIA because of vibration
05:46 PM * JT-Shop heads to the next problem...
05:48 PM HighInBC: good to know about
05:49 PM phipli: HighInBC: a Chinese 3040T would be enough
05:49 PM phipli: if you mean plastic boxes
05:49 PM HighInBC: the lids of these boxes have bolt holes, so I may be able to bolt them down to something with silicone under it: http://www.ebay.ca/itm/151732920131
05:50 PM HighInBC: ya plastic
05:50 PM phipli: JT-Shop: has someone turned the lights off when you weren't expecting it? :p
05:50 PM HighInBC: I am looking at the 3040t
05:50 PM phipli: HighInBC: I've cut holes for 1602 LCDs in boxes like that with mine
05:51 PM phipli: and cut pcbs with it
05:51 PM phipli: one sec...
05:51 PM HighInBC: pretty much waht I had in mind. Various panel mount buttons, switches, display etc
05:51 PM HighInBC: and perhaps some engraved labels
05:51 PM phipli: http://elephantandchicken.co.uk/projects/MikeBoard.jpg
05:51 PM phipli: things like that
05:52 PM phipli: The ABS boxes cut quite well
05:52 PM phipli: acrylic has been a pain for me
05:52 PM HighInBC: very nice. Rapid iteration with PCBs is a main goal
05:53 PM HighInBC: I use a lot of surface mount parts and breadboarding is just not very practical
05:53 PM HighInBC: you can only go so far with dead bug style
05:53 PM phipli: faster than getting fab'd
05:53 PM phipli: but a board like that still takes an hour to cut
05:53 PM phipli: that is about 90mm by 50 or so
05:53 PM HighInBC: That would make things so much faster
05:53 PM phipli: make sure you probe the surface first
05:54 PM HighInBC: yes I was reading up on that. Excellent tech
05:54 PM phipli: saves the tool / lets you take a smaller cut
05:54 PM * HighInBC ❤ transformational matrices
05:54 PM phipli: :)
05:54 PM phipli: I don't mind using them...
05:54 PM HighInBC: https://xkcd.com/184/
05:54 PM phipli: implementing them on the other hand...
05:54 PM phipli: lol
05:56 PM phipli: HighInBC: bit of surfacemount on this one : http://elephantandchicken.co.uk/projects/LEDboard0.jpg
05:56 PM phipli: I thought I'd be doing a lot more surface mount with it
05:57 PM phipli: but the auto drilling speeds through hole up so much I've not been so bothered
05:57 PM phipli: that chip is a SOIC8
05:57 PM HighInBC: I know it well
05:58 PM phipli: that usb connector was a pain to solder because I didn't have flux handy at the time
05:58 PM phipli: it was an ATTiny based RGB LED board
05:59 PM HighInBC: will have to get used to not having through hole vias
05:59 PM HighInBC: I just finished an attiny based RGB led board
05:59 PM phipli: :)
05:59 PM HighInBC: http://static.highinbc.com/USB_RGB_LED_draft.pdf
05:59 PM HighInBC: it is programmable over USB, and powered from USB. Has 3 x WS2812Bs on the top and the MCU and such on the bottom
05:59 PM phipli: attiny85++
06:00 PM phipli: I was lazy and the USB is only for power
06:00 PM HighInBC: going to add a vusb serial interface so that arbitrary software can control the LEDs
06:00 PM phipli: hence the 6 pin header
06:00 PM HighInBC: I only copied the digispark schematic hehe
06:00 PM HighInBC: used their bootloader
06:00 PM * phipli nods
06:00 PM HighInBC: 3 resistors and two zener diodes
06:00 PM phipli: I use digisparks to make mouse wigglers
06:01 PM phipli: and have a 328 based board upstairs
06:01 PM phipli: bootloader spoofs a usb programmer
06:01 PM tpra: gn, thanks for all the advises :)
06:01 PM phipli: night tpra
06:02 PM phipli: (mouse wigglers stop screensavers on computers that you don't have permission to turn off the screensavers "for security")
06:02 PM HighInBC: I was looking at this, was about to discount it as too small and not rigid enough but then noticed one guy in the comments saying he was doing PCB with it: https://www.amazon.com/gp/product/B01GFPW3LC
06:02 PM HighInBC: the price is right, but not sure about it
06:03 PM phipli: I got a ballscrew 3040 with a 300w spindle
06:03 PM HighInBC: looks like an arduino nano running it lol
06:04 PM phipli: HighInBC: it will be a GRBL machine
06:04 PM phipli: work well enough
06:05 PM phipli: If you can justify it I'd go for the 3040...
06:05 PM HighInBC: I am liking the 3040s but it seems hard to get one shipped to Canada without a huge shipping fee
06:05 PM HighInBC: like $200+ shipping
06:05 PM phipli: hum
06:05 PM phipli: you should be able to do better than that
06:05 PM phipli: where have you looked?
06:05 PM HighInBC: amazon, ebay
06:06 PM HighInBC: seems the sites only get sketchier as I go down the google searches
06:08 PM JT-Shop: lol putting some newspaper in the brooder I see the eclipse passes pretty close to me
06:08 PM phipli: HighInBC: they look like they've got more expensive since I got mine :s
06:09 PM phipli: I bought mine with a spindle, but no steppers or control box
06:09 PM HighInBC: more popular probably
06:09 PM roycroft: well the good news is that we still have fuel
06:09 PM phipli: wanted to do my own thing
06:09 PM roycroft: the bad news is that it has gone way up in price
06:09 PM roycroft: it went up $1.30/gallon near the freeway
06:09 PM HighInBC: I was thinking a frame and spindle was a good start, I am not afraid of building something from parts
06:09 PM HighInBC: as long as I have a plan
06:09 PM roycroft: and $0.34 at the filling station near my house
06:09 PM roycroft: it's $3.99/gallon along i5 right now
06:10 PM roycroft: yesterday it was $2.69
06:10 PM roycroft: i was able to fill up at $2.83
06:11 PM roycroft: i5 was pretty backed up too - i'm glad i only had to cross over it, and not drive on it
06:26 PM jdh: wh?
06:26 PM roycroft: eclipse on monday
06:26 PM jdh: so?
06:27 PM roycroft: a million people are coming to oregon to see it
06:27 PM jdh: so they gouge gas?
06:27 PM roycroft: and probably a million oregonians who live outside the path of totality are going to try to get to the path of totality
06:27 PM roycroft: it would appear so
06:28 PM jdh: I filled up for $2.09 this morning.
06:29 PM roycroft: monday is going to be nuts
06:29 PM roycroft: there will be no deliveries of food or fuel anywhere near the path of totality
06:29 PM jdh: I bet.
06:29 PM roycroft: when the filling stations and the grocery stores run out, that's it
06:29 PM jdh: I'm 90 miles from closest totality, but I'm just going to work.
06:29 PM Tom_L: oh what will they do...
06:30 PM roycroft: i'm on vacation
06:30 PM JT-Shop: Tom_L: you get your relays installed?
06:30 PM roycroft: and i'm about 20 miles from totality
06:30 PM roycroft: so i'm going to leave 5 hours early and hope i get there in time
06:30 PM Tom_L: JT-Shop, i did but i've got some issues
06:30 PM HighInBC: sooo glad we are not in the path of that tourist storm
06:30 PM * JT-Shop is on a dead end dirt road off a dirt road
06:30 PM roycroft: i'm also going to bring a book in case i get there in a half hour :)
06:30 PM HighInBC: tourists who swarm over for the day are the worst
06:30 PM Tom_L: JT-Shop good place to be
06:30 PM HighInBC: they will pack their lunches and spend as little as they can
06:31 PM roycroft: you should be pretty close to the path of totality, jt-shop, if you're not in it
06:31 PM Tom_L: JT-Shop, i've gotta go back thru my configs and see what i'm doing wrong
06:31 PM JT-Shop: I think it passes a bit north of me
06:31 PM roycroft: and you're also near one of the longest periods of totality
06:32 PM roycroft: sadly, i have enough fuel to get to the path of totality and back, and then up to my destination for my camping trip
06:32 PM roycroft: but not enough to get home
06:32 PM roycroft: so even though i'll be coming home on friday, after the craziness, i'll still have to pay inflated fuel prices
06:33 PM JT-Shop: about 1hr north of me
06:33 PM roycroft: because gasoline is way more expensive on the oregon coast than in the valley
06:33 PM jdh: do people live on the oregon coast?
06:33 PM jdh: seems stupid to type out loud
06:33 PM roycroft: a whole lot of people love on the oregon coast
06:33 PM Tom_L: they decided to play dark side of the moon here during the eclipse
06:33 PM roycroft: i'd like to live there, some day
06:34 PM jdh: but, in looking at google earth for the coast (south) it looks like no roads, no nothing
06:34 PM roycroft: i have heard side 2 of dsotm three times on the radio since yesterday
06:34 PM phipli: roycroft: time to implement fischer tropsch?
06:34 PM roycroft: that's what i get for listening to hippie radio stations, i guess :)
06:35 PM roycroft: time to just grit my teeth and pay the price
06:35 PM JT-Shop: Tom_L: one day my yet to be my wife got behind me in traffic and saw my bumper sticker... I love Pink Floyd lol she thought I was a country bumpkin
06:35 PM roycroft: fortunately i'm driving a prius these days, so i get really good fuel economy
06:35 PM Tom_L: heh
06:35 PM phipli: JT-Shop: you met because of the bumper sticker?
06:36 PM roycroft: last night i heard a live verion of side 2 after roger waters had left the band
06:36 PM phipli: or did you just break too hard?
06:36 PM JT-Shop: I heard the best of Johnny Horton so many times in my childhood I didn't like country music
06:36 PM JT-Shop: till later in life
06:36 PM JT-Shop: no, we worked at the same place
06:36 PM roycroft: richard wright did waters' vocals
06:37 PM * roycroft was privileged to see the band perform dsotm in '74
06:37 PM JT-Shop: had our 30th anniversary a few months ago
06:38 PM roycroft: they also did "echos", "astronimy domine" and a lot of other early stuff, but sadly, no "atom heart mother"
06:38 PM jdh: 30 years is a bunch!
06:38 PM roycroft: which i undestand - after dsotm and echos, it's hard to squeeze in another epoch tune like that
06:38 PM roycroft: but i'd lie to have seen ahm performed live
06:39 PM roycroft: i guess i'm just a wee bit too young for that
06:39 PM roycroft: i started going to concerts in '73
06:40 PM phipli: my dad saw them a couple of times
06:40 PM phipli: when they first got going in Birmingham
06:40 PM phipli: and then later in Covent Gardent
06:41 PM phipli: I think...
06:41 PM roycroft: i saw them in milwaukee wisconsin
06:41 PM roycroft: that was actually the only time i went to milwaukee for a concert
06:42 PM JT-Shop: phipli: I put the HikVision camera on the chicks what an over kill that thing can see real far at night
06:42 PM phipli: :)
06:42 PM roycroft: for some reason they did not play in chicago (where i livedat the time) that tour
06:43 PM roycroft: are you going to turn on floodlights during the eclipse, jt-shop, or are you going to watch the chickens go to roost?
06:43 PM phipli: just remembered something else
06:43 PM JT-Shop: I still need to install the weather proof box and seal tite into the garage for the HikVision camera, neat thing it has the same hole pattern as a weather proof round box
06:43 PM phipli: my parents met because of a Floyd concert
06:43 PM JT-Shop: chickens are 3 days old, other flock was killed by a dog
06:44 PM phipli: my dad gave my mum a lift after being asked to by a mutual friend
06:44 PM roycroft: oh, that sucks
06:44 PM JT-Shop: neat
06:44 PM JT-Shop: yea big time, one lived till the night and died... all I can say is dogs are dead and some don't know it yet
06:44 PM cncnoob: Hey guys, anyone have a Sieg X2 or the like which they have upgraded the bellows for? The stock way covers don't wrap around and I keep getting stuff on my ballscrews :(
06:45 PM phipli: cncnoob: got a sieg x2
06:45 PM JT-Shop: the dog that killed my flock is dead, emptied a whole clip into it
06:45 PM phipli: someone took the bellows off it
06:45 PM cncnoob: ah dang
06:46 PM phipli: has the gas strut upgrade and a belt drive
06:46 PM roycroft: i have an x3 clone
06:46 PM phipli: I have issues with the motor controller
06:46 PM roycroft: it did not come with no stinkin' bellows
06:46 PM cncnoob: I clean and put fresh oil on my screws before each milling and regardless of how careful I am they never stay perfectly clean. I even vacuum my chips during milling
06:47 PM cncnoob: How do you all keep your screws clean? Wipers? Or do you just not worry about it?
06:47 PM roycroft: whenever i finish the cnc conversion i'm going to install some bellows
06:47 PM phipli: Don't use it a whole lot, just clean it after every job
06:47 PM roycroft: and bed covers
06:47 PM cncnoob: what is the difference between a bed cover and a bellow?
06:48 PM roycroft: bed covers are flat
06:48 PM cncnoob: so they don't wrap around?
06:48 PM JT-Shop: fawn has lost it's spots... mom and fawn having dinner on my tab
06:48 PM cncnoob: I.E. they aren't "C" shaped
06:49 PM roycroft: well, yes, they are 'c' shaped
06:49 PM cncnoob: http://www.arceurotrade.co.uk/imagecache/23c60ae8-84e8-43f6-8b74-a79300f4604a_600x800.jpg
06:49 PM roycroft: but they're made of several c-shaped sections that overlap
06:49 PM cncnoob: On the Z axis, that is a bellow right?
06:49 PM cncnoob: ah
06:49 PM cncnoob: I think I have seen those
06:49 PM roycroft: whereas bellows are accordian-shaped
06:49 PM roycroft: a bellow is a single piece that can be extended and compressed
06:50 PM roycroft: a bed cover is several pieces that are rigid, but ride over each other
06:50 PM roycroft: over/under
06:50 PM SpeedEvil: Positive pressure ventilation is also a thing in some cases.
06:50 PM cncnoob: https://i.ytimg.com/vi/G2DJ8RQy4D4/maxresdefault.jpg
06:50 PM phipli: anyways.
06:50 PM cncnoob: like that?
06:50 PM phipli: night folks
06:50 PM cncnoob: phipli night
06:50 PM phipli: cncnoob: http://www.chris-builds.com/index.php/sieg-x2-7-mill-conversion
06:50 PM SpeedEvil: Blow clean air through a moderately closely fitting cover, and it keeps it clean
06:51 PM roycroft: and yes, that's a bellow on the z axis in that picture
06:51 PM phipli: someone elses conversion
06:51 PM SpeedEvil: Positive oil pressure can also be used, in some cases.
06:51 PM roycroft: i should get back to prepping for my trip
06:51 PM roycroft: it's been a busy summer, and i still haven't put everything away from the country fair
06:52 PM roycroft: i have to go do that, so i have room to stage my camping gear in my garage for my trip next week
06:52 PM roycroft: i also had to build a new roof carrier for my car, as it doesn't have as much cargo space as my old car, and i'll need to haul some of the camping gear topside
06:53 PM roycroft: there's one more coat of spar varnish to apply, and hopefully it will be dry enough by tuesday to not be sticky
06:53 PM roycroft: i'll leave it out in the sun tomorrow and monday
07:24 PM rodweb: JT if you are still there, eoffsets pid tuning does not seem to like super fast acceleration. Signal gets quite noisy (from overshoot I suppose)
10:51 PM minibnz: my lathe stopped working last night :( its a sx3 sieg.. its in bits at the moment.. i just measured the coil windings on the motor and they seem fine.. hoping the ebay seller will honor their warranty as its only 10moths old..
10:51 PM minibnz: otherwise its about $240au to replace the control board..
10:55 PM minibnz: i went to spin up a mirror for the co2 laser i am building and the chuck wouldn't spin the lights were on but the rat was not hoe to run the wheel..
10:58 PM Tom_L: you forgot to feed it
11:00 PM minibnz: possibly..
11:02 PM minibnz: not sure if this is a good thing or a bad thing... i was waiting for the warranty to run out before i CNC the little thing...
11:04 PM minibnz: atm trying to build some parts for the laser. god i hate working with high voltage.. i have a 1750watt 50kv power supply.. claims to be good enough for 180w tubes...
11:06 PM minibnz: starting by makiing a smallish single tube then moving onto a folded 4 tube laser.. hope to be able to cut 5mm steel and ally...
11:08 PM Tom_L: just don't burn the place down
11:08 PM minibnz: well was kinda more worried about electrocuting my self..
11:08 PM minibnz: having the neighbours kicking in my door in a few weeks once the smell gets real bad.
11:10 PM minibnz: am kinda wonding if its possible to make a semi sealed laser.. xenon gas is kidna hard to get a hold of..
11:10 PM minibnz: i did think maybe i could get enough from smashing headlights in a bucket of water to catch the gas from them..
11:11 PM minibnz: i have glasses already to go so as long as i use them i should be able to keep at least one eye functional..
11:14 PM minibnz: worst part so far seems to be getting a 1gig ohm resistor that can handle 50kv for the voltage gauge.. i have made me a current sensor that should be good for 50kV 125mA.. the resistor for the voltage display is going to cost me $40
11:28 PM SpeedEvil: https://www.youtube.com/user/niffi2/videos - on the topic of 'channels you wish had more info on their projects'
11:28 PM SpeedEvil: A model multistage axial compressor jet engine that produces nonzero thrust.
11:30 PM SpeedEvil: minibnz: or just use 100 10M resistors in series.
