01:42 AM Tom_L: asrock q1900 after a bit
01:42 AM Tom_L: buster rtai
06:53 AM Tom_L: morning
07:39 AM perry_j1987: morning
07:41 AM perry_j1987: hows everyone doing
07:49 AM dirty_d: Tom_L, were those numbers better or worse than the kernel you were using beforehand?
08:53 AM Eric__: Tom_L those numbers don't look that good.
09:11 AM veegee: Anyone have any recommendations for a PAPR helmet?
09:17 AM methods_: a small garbage can?
09:19 AM Centurion-Dan2 is now known as Centurion_Dan
09:21 AM methods_: http://www.sector67.org/blog/2020/diy-powered-air-purifying-respirator-papr/
09:21 AM veegee: Ok my fault for not being more clear
09:21 AM veegee: Can anyone recommend an auto darkening welding helmet with PAPR?
09:24 AM methods_: oh hahahahah
09:24 AM methods_: i thought you were trying to capitalize on all this diy pandemic hysteria
09:25 AM methods_: 3m with the speedglas helmet
09:26 AM jymmmm: If you are thinking of getting a jump pack, this is a great video... https://www.youtube.com/watch?v=JN8A2nIMUWA
09:27 AM methods_: https://www.amazon.com/3M-00051141561578-36-1101-20SW-Speedglass-Standard/dp/B076DFYH31
09:28 AM methods_: https://www.amazon.com/dp/B017H5WVCU
09:28 AM methods_: that's the jackson safety helmet which i also like
09:28 AM methods_: the view is quite a bit diff than the speedglas though
09:29 AM veegee: I have a Viking FGS helmet (non PAPR) and its sensitivity is garbage and the auto darkening turns off during TIG welding at lower currents
09:29 AM veegee: so I'm going to return this and get a PAPR helmet while I'm at it
09:29 AM methods_: now is a horrible time to buy anything with the letters papr in it
09:29 AM veegee: Also fucking americans making life difficult with their shitty units: "Thermal Conductivity: 224 Btu/ft2/ft/hr/°F at 68°F"
09:30 AM veegee: what the FUCK is 224 Btu/ft2/ft/hr/°F at 68°F
09:30 AM methods_: i have no idea sounds dangerous
09:30 AM veegee: Fuck BTU and whichever asshole came up with it. How hard is it to use Joules/Watts/Kelvin/meter
09:31 AM veegee: I'm selecting a copper alloy and the book is otherwise good, just uses shitty american dictatorship units
09:33 AM veegee: jymmmm yeah those things are crap. I make my own u sing ultracapacitors or LiFePO4 cells that can easily output 2,000A
09:33 AM jymmmm: veegee: he reviews one of those too. But the Audew did great actually
09:34 AM veegee: regular li ion degrades fast when stored at high charge voltage
09:34 AM veegee: I avoid for anything I aim to keep for a long time
09:34 AM dirty_d: for the helmet couldn't you just use one of those clear plastic face shields, and like glue some kind of plastic to the edges that goes around your head and forms the rest of it?
09:34 AM jymmmm: veegee: Well, I don't have a supply of batteries like it sounds that you do have
09:34 AM dirty_d: maybe put a zipper in the back
09:35 AM veegee: dirty_d yeah I considered DIY, but I'm going to be doing a lot of welding/grinding and don't mind paying for something I know can keep me safe
09:35 AM methods_: you could just use a 6mil poly bag with a box fan and hepa filter hangin off the back of your head
09:35 AM veegee: Again, need it to be an auto darkening welding helmet
09:35 AM dirty_d: oh, I figured this was a for fun apocalypse build
09:36 AM methods_: that's what i thought at first too
09:36 AM veegee: ideally with a flip up lens part that has a regular clear face shield for grinding
09:36 AM methods_: i haven't tried that optrel helmet
09:36 AM dirty_d: I mean, if you did the same thing with an auto darkening welding helmet, it wouldn't be so bad
09:36 AM dirty_d: and it would be very easy to fix
09:36 AM methods_: yeah that 3m speedlgas fits' that description
09:36 AM jymmmm: just toss a heavy mil trash bag over your head and duct tape tightly, Will keep youe perfectly safe. PSA: Don't try this at home kids
09:37 AM methods_: just fill the bag with bleach first jymmmm
09:37 AM veegee: This looks decent: https://canadaweldingsupply.ca/collections/papr-purified-air-powered-respirator-welding-helmets/products/3m-speedglas-9100fx-with-adflo-papr-system?variant=13920574177324
09:37 AM veegee: really expensive though, but I don't skimp on safety
09:37 AM jymmmm: methods_: Eh, waste of perfectly good bleach
09:37 AM methods_: yeah that's it veegee
09:37 AM veegee: I already got HIV from raw dogging a
09:37 AM veegee: whoops wrong channel
09:38 AM veegee: methods_ there's also this one: https://canadaweldingsupply.ca/collections/papr-purified-air-powered-respirator-welding-helmets/products/3m-speedglas-g5-01-papr-flip-up-welding-helmet-46-1101-30ivc
09:38 AM veegee: not sure of the difference between the two'
09:40 AM methods_: it's the filter glass
09:40 AM methods_: the 2nd one is better
09:40 AM methods_: got the newer filter style on it
09:40 AM veegee: Is the glass better than the 9100XXi?
09:41 AM methods_: https://www.awsi.com.au/blog/what-are-the-key-differences-between-the-speedglas-g5-01-and-the-speedglas-9100-fx-air
09:42 AM methods_: i don't know exactly
09:44 AM dirty_d: does anyone know of a way to find what the current g54-g59.3 coordinate system is outside of g-code?
09:45 AM dirty_d: my pendant shows it, but there is nothing in the hal file that has anything to do with that
09:46 AM dirty_d: oh!
09:46 AM dirty_d: it must be reading linuxcnc.var
10:13 AM jymmmm: veegee: Where are you getting the batteries from?
10:13 AM jymmmm: veegee: the LiFePO4 ones you spoke of?
10:15 AM veegee: jymmmm I forgot, but there are a lot of sources for EV cells. The high power ones with a very good reputation are the A123 cylindrical cells: https://www.imrbatteries.com/a123-systems-anr26650-2500mah-50a-battery/
10:16 AM veegee: jymmmm any of these are just as good: https://www.evcomponents.com/lifepo4-cell.html
10:16 AM veegee: Yttrium added to the cell (LiFeYPO4) improves low temperature performance
10:17 AM veegee: LiFePO4 is my favourite chemistry. Very long calendar life, very long cycle life, very safe, high power
10:18 AM veegee: https://www.bluesea.com/resources/108/Electrical_Conductivity_of_Materials hmm no wonder Nickel is so easy to spot weld
10:19 AM veegee: But looks like many contact points are needed and a lot more conductor for making high current battery packs
10:33 AM veegee: https://www.princessauto.com/en/detail/-1-0-gauge-2-bolt-reuseable-welding-cable-lug/A-p8851842e lol "Brass construction for maximum conductivity". Need to copper plate that shit
10:37 AM Tom_L: dirty_d, Eric__ the gigabyte was about the same as my D525 with Wheezy
10:38 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/screenshots/D525_Latency_Wheezy.png
10:38 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/screenshots/Gigabyte_i5_MB_Buster_RTAI.png
10:38 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/screenshots/ASRock_Q1900_MB_Buster_RTAI.png
10:39 AM Tom_L: the ASRock Q1900 wasn't as good but maybe useable with mesa cards
10:53 AM Eric__: not sure I understand why the jitter is so much worse on the base thread
10:54 AM Eric__: it makes sense that it's a little worse, but if you run long enough the servo thread should still see some .1ms delays
11:06 AM jymmmm: veegee: those cell ends look like bolt heads (sorta)
11:52 AM dirty_d: hmm, when I switch coordinate systems linuxcnc writes the previous coordinate system to linuxcnc.var instead of the one just switched to
12:00 PM Tom_L: dirty_d, are you using axis?
12:01 PM dirty_d: yes
12:01 PM dirty_d: I'm trying to get the current coordinate system from a hal component
12:01 PM Tom_L: did you select the right G54-59 offset from the drowdown?
12:01 PM dirty_d: Tom_L, I entered g54, g55 etc in MDI
12:02 PM Tom_L: not sure how that's done
12:02 PM Tom_L: you may need to select 0-xx
12:02 PM dirty_d: I know i can use M66 to write to an analog output, but that would require rebasing g54-g59.3
12:02 PM dirty_d: which im not even sure if you can do
12:03 PM Tom_L: g10 L2
12:03 PM dirty_d: either that or have a timer run an MDI command
12:03 PM Tom_L: read that part
12:03 PM dirty_d: that's not what I mean, I mean i want to show G54 or G55 etc on my pendant
12:04 PM dirty_d: it's already showing the current relative coordinate
12:04 PM dirty_d: just not which coordinate system that is in
12:04 PM Tom_L: oh, i'm not sure how to do that
12:04 PM Tom_L: you might ask in #hazzy, i know the qtpycvp ppl have been working on that sort of thing
12:04 PM dirty_d: I think I'm gonna have to just use a periodic timer, im assuming that's a thing
12:05 PM Tom_L: they may have a better way to access it
12:05 PM Tom_L: i know Lcvette is using a wireless pendant
12:06 PM Tom_L: it may display that info i dunno
12:13 PM dirty_d: Tom_L, I think I can use this http://linuxcnc.org/docs/2.8/html/config/python-interface.html#_linuxcnc_stat_attributes
01:03 PM roycroft: j ##homebrew
01:03 PM roycroft: ack
01:14 PM dirty_d: hmm, not sure if I found a bug. When I open linuxcnc it shows G53 on the DRO, but on the MDI screen it shows G54
01:15 PM dirty_d: The DRO wont change till I change to something other than g54
01:15 PM dirty_d: setting it back to g54 afterward does show g54 on the DRO
01:17 PM dirty_d: EMC_STAT::task.g5x_index is also 0 until i change to something other than g54
01:17 PM skunkworks: G53 really isn't a modal mode.
01:17 PM dirty_d: yea exactly
01:17 PM andypugh: G53 is not modal. That is to say you can’t be _in_ G53
01:17 PM dirty_d: right, so why is it showing that on the DRO?
01:18 PM dirty_d: im using axis
01:18 PM andypugh: Which DRO? (Which GUI?)
01:19 PM andypugh: That might be a shortgut to indicate machine-absolute coordinates.
01:19 PM skunkworks: mine boots up saying G54
01:19 PM dirty_d: I could have swore mine did too an hour ago
01:20 PM skunkworks: (it is 2.7)
01:20 PM dirty_d: I'm using 2.8
01:21 PM dirty_d: (debug, #5220) also shows 1
01:24 PM dirty_d: I think it might have happened after I started using NML in my hal component
01:24 PM dirty_d: but I commented out all the code, and it's still doing it
01:27 PM andypugh: Start up the sample config sim-axis and see what that does.
01:28 PM dirty_d: it shows G54
01:29 PM dirty_d: what the hell did I do
01:32 PM dirty_d: its, something that my MPG is doing
01:32 PM andypugh: Which MPG?
01:32 PM dirty_d: if I comment out the hal file it starts in G54
01:33 PM dirty_d: I have a vistacnc p2-s, but I've created my onw userspace hal component for it
01:34 PM andypugh: Is the pendant component capable of changing coordinate system?
01:39 PM dirty_d: no
01:39 PM andypugh: That’s wierd
01:39 PM dirty_d: I narrowed down the problem though, it has something to do with how I set up the estop
01:39 PM andypugh: But you spotted that.
01:39 PM dirty_d: halui.estop.activate and halui.estop.reset
01:43 PM dirty_d: it was because my component sets halui.estop.reset to 1 whenever the estop isn't pushed in
01:43 PM dirty_d: I guess that's not what I'm supposed to do, better read
01:43 PM andypugh: That’s a very odd place for a “because”
01:44 PM andypugh: It doesn’t make any sense to me.
01:44 PM dirty_d: yea me neither
01:48 PM Tom_L: andypugh, is rtai 5.2 quite a bit different than the older ones?
01:48 PM andypugh: I don’t really know
01:48 PM Tom_L: i'm kinda wondering how bad it would look if i plugged buster into my d525 on the mill
01:49 PM andypugh: It might not even install. It won’t on my older board
01:49 PM Tom_L: i've got the install, just swap machines
01:49 PM Tom_L: see if it boots
01:50 PM Tom_L: linux doesn't seem to mind that too much
01:55 PM dirty_d: andypugh, the issue was that when my estop button is not pushed the hal component was doing `estop_activate=0; estop_reset=1` when it should have been doing `if(estop_activate){ estop_activate=0; estop_reset=1 }`
01:56 PM dirty_d: its weird that the only problem that caused was showing G53 on the DRO
02:15 PM andypugh: These micro-steppers are fun. I have one running at 5000rpm from the 5V supply of the Mesa card, using the Pololu low-voltage driver.
02:15 PM Tom_L: you're bound to blow another ehh?
02:16 PM andypugh: At 10p each that’s not a majot worry.
02:17 PM andypugh: I am thinking about making a flex circuit to have an integrated driver.
02:17 PM XXCoder: tiny and fast eh
02:18 PM XXCoder: you could make bush locomation robot
02:35 PM andypugh: I was thinking about having a flex-pcb made for these little motors, but they appear to be a lot more expensive than FR4
02:42 PM Tom_L: andypugh do you know where the source for 2.8 went?
02:42 PM andypugh: Eh?
02:43 PM Tom_L: i cloned the repo and tried to checkout 2.8 and it said 'new'
02:43 PM rmu|w: Tom_L: https://github.com/LinuxCNC/linuxcnc/tree/2.8
02:43 PM Tom_L: so it's separate now?
02:43 PM rmu|w: no
02:43 PM andypugh: I don’t understand the question
02:44 PM Tom_L: i used to be able to git branch and git checkout 2.8
02:44 PM andypugh: If you had previously only had the master branch open then, yes, it will create a new local 2.8 branch
02:44 PM Tom_L: i'm not that good at git either
02:45 PM Tom_L: ok but the new branch would be 2.8?
02:45 PM Tom_L: i don't remember it that way but ehh
02:45 PM Tom_L: is there a way to get those as a menu item?
02:46 PM Tom_L: from the compile
02:46 PM Tom_L: i've never done or tried that
02:46 PM Tom_L: instead of running from a terminal
02:50 PM andypugh: git gui?
02:50 PM Tom_L: no, cmd line
02:50 PM Tom_L: not sure what you're asking
02:51 PM Tom_L: to build or to run it?
02:55 PM dirty_d: Tom_L, just do git checkout 2.8
02:57 PM Tom_L: yeah i did but i wasn't expecting to see 'new'
02:57 PM dirty_d: yea confusing
02:57 PM Tom_L: i just don't do it often enough
02:59 PM rmu|w: Tom_L: what does "git status" say?
03:16 PM CaptHindsight: RTAI jitter has much to do with how crappy the BIOS is
03:17 PM CaptHindsight: but since mere mortals are not allowed to write their own firmware you're pretty much stuck with the hack job the OEM puts in it
03:18 PM dirty_d: CaptHindsight, isn't the bios only used during power on?
03:18 PM Rab: CaptHindsight, what's your preferred source for the cheap CH382L cards?
03:19 PM CaptHindsight: dirty_d: BIOS configures the hardware, so if it does a crap job you're stuck with it no matter what the OS does
03:20 PM CaptHindsight: Rab: ebay or Amazon
03:20 PM XXCoder: there might be bios updates
03:20 PM dirty_d: CaptHindsight, I thought the bios was just code that's loaded into memory on power on that the cpu executes
03:20 PM dirty_d: can't the os just unfuck what the bios messed up when it loads?
03:20 PM Rab: I've found a few on eBay, but I've also found variants with the first and second serial port stuff populated. I can see CH382L on the main chip in the product photos. Not sure if those are now supported by the kernel driver, or if those ports have to be disabled in the card for it to work.
03:20 PM dirty_d: or does it not know what to do
03:21 PM Rab: E.g. https://www.ebay.com/itm/231334659543
03:21 PM CaptHindsight: dirty_d: nope, lots of registers are configured via a complex chain of hoops
03:22 PM dirty_d: oh, hmm
03:23 PM CaptHindsight: we used to laugh about how it was like you might have to set some magic register first with some setting, then set 30 others, then climb though a window and set registers that were set before, then close the window and open a door and set some others again
03:23 PM CaptHindsight: they fix lots of hardware mistakes with BIOS
03:24 PM CaptHindsight: Rab: I never use the 1S 1PP version
03:24 PM CaptHindsight: use/used
03:25 PM CaptHindsight: Rab: I think they have each version of that chipset driver in the kernel now
03:26 PM dirty_d: it would be cool if the parts of linuxcnc that need to be realtime could be separated and just run on bare metal
03:26 PM MarkusBec: the problem with bios in the last 20-30 years
03:26 PM CaptHindsight: one can only dream
03:27 PM MarkusBec: they are firmware that is executed at runtime
03:27 PM dirty_d: I mean its doable in principle
03:27 PM CaptHindsight: AMD provided BIOS specs until about 10 years ago, then it was just too dangerous for us to have control over our hardware
03:28 PM MarkusBec: something like the controll loop for your termalmanagment is not a dedicated processor its just some calculation time on the main cpu handled by code in the bios
03:28 PM CaptHindsight: they CAN do all sorts of things to make things better, but they DON'T
03:28 PM CaptHindsight: because our devices have to be secure from us vs for us
03:29 PM MarkusBec: if you want to see a real bad bios/efi us HP hardware
03:30 PM MarkusBec: the do things like stopping the cpu for some ms just to control fans :)
03:30 PM CaptHindsight: Rab: https://www.ebay.com/itm/PCI-E-Express-DB25-Parallel-LPT-Printer-Port-Card-WCH-CH382L-Chipset-US-Stock/183132128667
03:30 PM CaptHindsight: EFI is complete train wreck of an OS
03:31 PM MarkusBec: its just fine
03:31 PM MarkusBec: problem is bad implementation
03:31 PM MarkusBec: most at cheap mainboard :)
03:31 PM CaptHindsight: Rab: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?WCH
03:32 PM CaptHindsight: fine train wreck agreed :)
03:34 PM CaptHindsight: they could have used Linux as EFI but then they wouldn't have control
03:34 PM CaptHindsight: bbl
03:35 PM rmu|w: intel processors actually run MINIX on their SME
03:49 PM Rab: CaptHindsight, thanks!
04:13 PM adamj12b: Good Evening!
04:14 PM adamj12b: I am having an issue of axis on my mill drifting after running for some time. I am using a 6i25 > 7i77 with DMM Dyn4 servos.
04:15 PM adamj12b: I suspect the encoder signals are picking up noise. They are connected using cat5e cabling from the Dyn4 to 7i77.
04:16 PM adamj12b: I am confident it is not mechanical.
04:26 PM Deejay: gn8
05:13 PM -!- #linuxcnc mode set to +v by ChanServ
05:44 PM jymmmm: Upgrade your iphone https://www.youtube.com/watch?v=rHP-OPXK2ig
05:49 PM _unreal_: ve7it, starting to put the box together
05:49 PM _unreal_: getting parts installed located
05:50 PM _unreal_: I doubt I'll have the motor controller box setup and working by this weekend but it would be fun if I did
05:50 PM _unreal_: ve7it, the more I think about it. i should have put headers on the LED location. so i could do external LED's for activity
05:50 PM _unreal_: sigh
05:52 PM _unreal_: jymmmm, used the projector yet?
05:54 PM ve7it: _unreal_, good work... good luck... was amazed at the pictures of the box... I think a 7 year old with a jig saw would have cut straighter lines
06:01 PM _unreal_: ya I idnt cut them :(
06:02 PM _unreal_: my friend who is an ACE welder and a bit of a BIT of a drinker tacked it
06:02 PM _unreal_: :(
06:02 PM _unreal_: was supposed to fold it on a bar break at his job but theres was not usable
06:02 PM _unreal_: SOOOO
06:02 PM _unreal_: he did it at home
06:02 PM _unreal_: sigh
06:03 PM _unreal_: I'm building everyhing modular so I'm going to use the box for now JUST to get things working and I'm going to build a new box as time allows A NICE box
06:06 PM CaptHindsight: rmu|w: it could have been as simple as a about 100 lines of assembly and then Linux to replace BIOS
06:29 PM JavaBean|new is now known as JavaBean
06:49 PM Loetmichel: _unreal_: thats the box a coworker made for his private machine... -> http://www.cyrom.org/palbum/main.php?g2_itemId=17547&g2_imageViewsIndex=1
06:50 PM XXCoder: unable to connect
06:50 PM Loetmichel: aka: he got a damaged PC enclosure from the company and made new front and back panels
06:51 PM Loetmichel: XXCoder: hmm, works fine here
06:51 PM XXCoder: try full refresh see if fine
06:51 PM Loetmichel: i did
06:53 PM Loetmichel: cant find the links to unreals box though
06:56 PM andypugh: I like my boxes less blurry,
06:56 PM XXCoder: still no luck for me
06:57 PM Loetmichel: yeah, andypugh. my smarthone dosent like low light
06:57 PM Loetmichel: sorry for that
06:58 PM Tom_L: odd your wounds come out crystal clear :)
06:59 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=14145&g2_imageViewsIndex=1 <- same box as this one, slightly different cutouts though
06:59 PM Loetmichel: Tom_L: maybe thats because i dont have a tremow when i make those? ;)
06:59 PM Tom_L: you do make some nice boxes..
07:00 PM Loetmichel: its our standard PC enclosure
07:00 PM Loetmichel: 3mm alu, welded "watertight"
07:00 PM andypugh: And how much does one cost?
07:00 PM Loetmichel: the one the coworker got just had scratched paint
07:01 PM Loetmichel: complete PC: around 8kEur++
07:01 PM Loetmichel: just the box: no idea
07:01 PM andypugh: Seems a _bit_ much.
07:02 PM dirty_d: yikes
07:02 PM andypugh: Though perhaps the testing is expensive?
07:03 PM andypugh: It hits my “could I make one a month and be happy and well paid” metric
07:04 PM Loetmichel: Military hardware
07:05 PM Loetmichel: the testing is expensive aka: the measurement chambers are pretty expensive (about 1 million in Rhode&schwarz tech in each)
07:06 PM Loetmichel: dirty_d: its special PCs shielded against eavesdropping over air. and yes, we can certify that
07:06 PM andypugh: That was what I was thinking must be the case.
07:07 PM andypugh: Are they all individually tested>
07:07 PM Loetmichel: like the cents cheap m8 bolt that suddenly cost $30 if its with all the certifications for an aircraft
07:07 PM Loetmichel: yes
07:08 PM Tom_L: who mined the ore that made the billet that.....
07:10 PM Loetmichel: andypugh: also the parts we use are not the cheapest sometimes... the shielding glass i put in front of the 42" TFT i made lately was 1300 eur
07:10 PM Loetmichel: PLUS VAT
07:10 PM Loetmichel: ;)
07:11 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17788&g2_imageViewsIndex=1 <- that monitor
07:11 PM andypugh: Loetmichel: Not just aircraft. Cars and motorcycles too. You are not paying for the washer, you are paying for the bag that says it is the correct washer and that it is there for you in the workshop.
07:12 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17690 <- looks like this from the front
07:12 PM flyback: rue_mohr is such a coward
07:12 PM Loetmichel: aircraft was just an extreme example
07:13 PM Loetmichel: also we do small production runs
07:13 PM Loetmichel: 1 to 100 pcs of each
07:13 PM Loetmichel: and lots of german manual work. also not cheap ;)
07:14 PM Loetmichel: but it sure is nice to see your CAD come to life. -> http://www.cyrom.org/palbum/main.php?g2_itemId=17779&g2_imageViewsIndex=1
07:15 PM Loetmichel: (thats the 42" when i designed the enclosure)
07:16 PM Loetmichel: its why i love doing prototype work in a small company. from the idea to the finished product all in one person
07:17 PM Loetmichel: not that many companies where you can have that these days
07:17 PM Loetmichel: (as in designing it, making the mill files, milling the alu, bending it, drilling the holes, put the electronics in etc.
07:22 PM Thorhian: So I have gotten some of my parts for the mill I'm going to build.
07:23 PM Thorhian: Ballscrews, 3 stepper motors, my BLDC spindle motor. I'm quite excited!
07:23 PM XXCoder: :)
07:23 PM Eric__: does "icloud locked" mean the board is from a stolen phone?
07:27 PM Thorhian: I think I underestimated the size of 16mm ballscrews lol. Same with the NEMA 24 sized motors.
07:31 PM jymmmm: Eric__: icloud locked means the phone can only be erased, used, or reactivated upon entering the owner's device pincode or their iCloud password.
07:32 PM Eric__: I'm curious where you get a lifetime supply of them, like he ruined in that video
07:32 PM jymmmm: Eric__: supply of?
07:34 PM Eric__: Cap'n posted a link to a video of replacing the iphone flash chip. He practices on 16 icloud locked boards before he does the real upgrade
07:36 PM Eric__: oh, you posted a link to a video of upgrading flash on an iphone
07:40 PM jymmmm: Eric__: Yeah, he bought 10 practice boards before doing a real phone =)
07:42 PM andypugh: Loetmichel: I had that for a while, great little company making testing rigs. One table of 3 mechaicals, one of three electricals, one of three software, all in the same ropm.
07:43 PM Eric__: jymmm he boguth more than that, he went back and got more
07:44 PM Loetmichel: andypugh: where i am its one person doing all that... me ;)
07:45 PM Loetmichel: and considering that i was hired as a production manager, not a designer or machine operator... ;)
07:51 PM andypugh: We also had an inspector, two wiremen and a machinist.
07:52 PM andypugh: (The inspector was absolutley not dead weight, he did a lot of rectification)
07:58 PM andypugh: So he also did final assembly and sign-off. So he would question the machinst if the part wasn’t to the the drawing, or the designer if it was but didn’t fit, and would hand-fit if it was close
08:08 PM _unreal_: same saw it just fine
08:08 PM _unreal_: the image of the box
08:54 PM veegee: Ugh I accidentally bought 3 packs (30 rods in total) of 3/32" 2% Lanthanated tungsten electrodes
08:55 PM veegee: so much tungsten, no idea what to do with it
08:55 PM dirty_d: reinvent the lightbulb
08:55 PM veegee: I meant to get 1/16" and 1/8"
08:56 PM XXCoder: fancy
08:56 PM XXCoder: hmm
08:57 PM XXCoder: use it as rails for really tiny machin
08:57 PM veegee: The CK torches with the flexible cable are really nice though
09:26 PM dirty_d: is this actually what I think it is? https://www.lafoauto.com/products/type-e-1-2-28-5-8-24-single-core-fuel-filter-6-black-titanium?variant=33297833328685
09:27 PM dirty_d: 0.405" Diameter holes of the internal baffles
09:27 PM dirty_d: you wouldn't need to know that for a fuel filter
10:14 PM XXCoder: dirty_d: that was linked before, and yes i is
