[00:24:04] <jesseg> Howdy
[00:36:57] <jesseg> hey guys is it considered shady practice to use a large transistor as a crude constant current source by hanging a resistor off the gate to the other power rail such that the HFE of the transistor and the base current work out to be approximately the desired current -- like for a stepper motor?
[00:41:51] <pcw_home> Typically you use an emitter degeneration rather than the ( widely variable) HFE to make a constant current source/sink with a transistor

[00:50:51] <jesseg> yeah but it was just an idea i had
[00:52:16] <jesseg> actually an LM317 can make a nice constant current source too with a power resistor of 1.25 ohms per amps so to speak

[07:00:13] <XXCoder> other team 189 128 76
[07:06:51] <jthornton> hmm I've figured out why my library won't work now to figure out why it's not installed in /home/pi/.local/lib/python3.5/site-packages

[07:27:16] <miss0r> I'm looking for an icon/pictogram of a steel strength test - the one where you pull something apart. Do you guys have an idea where I can find stuff like that?
[07:27:22] <miss0r> (making a t-shirt for a friend)
[07:28:17] <miss0r> also, I'm not even sure what the english term is, perhaps that could help as well :)
[07:28:28] <XXCoder> isnt there standard material shape for that? is that what you mean?
[07:28:38] <SpeedEvil> Outline of tensile test coupon with fracture/neck?
[07:28:57] <jthornton> tensile test
[07:28:59] <SpeedEvil> https://www.admet.com
[07:29:13] <miss0r> something like that, yeah
[07:29:41] <XXCoder> http://www.baileymetalprocessing.com ?
[07:30:41] <XXCoder> or maybe http://testlabs.ca
[07:31:20] <miss0r> A friend of mine; ex soldier. got a job where he does the stress test of steel. He was blown up in afghanistan(realy badly, sole survivor out of 5 in an APC), he started hating the booms from the steel being torn apart, now he has come to the job.. So I'm going to make him a t-shirt with a picture like that, and a text saying "Destroyer of stuff.. and things"
[07:31:50] <SpeedEvil> Perhaps several coupons exhibiting different failures
[07:31:56] <miss0r> if I could find a picture of what you posted lastly, xxcoder, just in "pictogram" form, that would be cool
[07:31:59] <SpeedEvil> With brittle, necked, original, ...
[07:32:14] <miss0r> sure - but my skills are limited to paint ish
[07:32:20] <SpeedEvil> 'find' ? It's five lines or so.
[07:32:23] <miss0r> so, I was hoping to find something online :)
[07:33:02] <SpeedEvil> And they are not artistic lines which have to look right, but simple geometries
[07:33:16] <miss0r> I'll have a go at paint then :)
[07:34:01] <XXCoder> which one?
[07:34:12] <XXCoder> I linked to 2 pictures :)
[07:34:16] <miss0r> the 'flat bar' one
[07:34:28] <miss0r> http://www.baileymetalprocessing.com
[07:34:44] <XXCoder> ahh yeah simple enough to remove some unnesscary stuff
[07:34:57] <XXCoder> maybe the table below remove
[07:35:17] <miss0r> I've decided to model one in MasterCAM
[07:35:22] <miss0r> That I should be able to do
[07:35:51] <XXCoder> ah more 3d style. yeah that sheet should help you easily make one
[07:36:47] <miss0r> hehe.. not 3D :) just a simple flat.
[07:37:02] <miss0r> the t-shirt guy is very limited to what he accepts
[07:37:07] <XXCoder> lol ok
[07:37:45] -!- emsjessec has quit [Quit: Leaving]
[07:41:42] <miss0r> Do any of you know how to make 'null' color in pain? :)
[07:41:57] <miss0r> for some reason it is determined to put a 'frame' around the print on the t-shirt
[07:42:25] <XXCoder> set alpha to 0
[07:42:32] <XXCoder> paint areas you wanna be transparent
[07:42:45] <XXCoder> file format must support it, likely PNG
[07:43:29] <miss0r> alright, giving it a go
[07:45:17] <miss0r> apparently I cannot.
[07:45:48] <XXCoder> any hints on site how to transparent areas
[07:46:13] <SpeedEvil> CNC out a bit of wood, apply ink to wood, apply wood to t-shirt.
[07:46:30] <miss0r> I'm reading on google. and it would seem I'd need to download seprate software to do the transparent part in ms paint :]
[07:46:40] <miss0r> SpeedEvil: I would, but my cnc is pretty occupied at the moment
[07:46:48] <XXCoder> wtf
[07:46:59] <XXCoder> youre using ms paint?
[07:47:09] <miss0r> Its all i've got on this PC
[07:47:16] <XXCoder> inkscape is free
[07:47:22] <XXCoder> you could make vector image and export
[07:47:30] <miss0r> sure, but I still don't have it on here :]
[07:47:38] <XXCoder> got internet? :)
[07:47:49] <miss0r> Is that a trick question? :)
[07:48:11] <XXCoder> https://inkscape.org
[07:48:11] <miss0r> I'll have to pick up on it later. I'll download inkscape
[07:48:15] <XXCoder> lol ok

[13:42:05] <Tom_itx> wow, real chatty day
[13:44:38] * Loetmichel is not feeling well... i think i will have a full blown cold today. cant even speak at the moment. It was hard enough to work thru the day today, even without my usual comments here ;)
[13:45:37] -!- MaPo has joined #linuxcnc
[14:04:45] <fragalot> Loetmichel: have some of JT-Shop's famous chicken soup
[14:13:03] <SpeedEvil> https://i.imgur.com UPS delivers.
[14:17:39] <fragalot> good door
[14:20:53] -!- gloops has joined #linuxcnc
[14:22:25] <gloops> whats the 5 axis CAM addon gregcnc suggests to try, ive lost the link and forgot what its called
[14:23:43] <gregcnc> http://www.cnc-toolkit.com
[14:25:49] <gloops> thanks again, may help someone out
[14:26:00] <CaptHindsight> SpeedEvil: was not packed properly, it should have at least 50mm of cushion on all sides
[14:29:43] <Tom_itx> gregcnc, have you used that?
[14:30:26] <Loetmichel> speedevil: indeed. how dou you manage to break a door?
[14:31:09] <Loetmichel> or was it the "inner door" cardboard core with some veneer on the outside?
[14:31:17] <gregcnc> I have not. it's not an ideal CAM, but seems capable if you figure it out. Some nice parts have been made with it, though i don't know how much effort was involved

[14:33:34] <roycroft> i have a parcel that was due yesterday
[14:33:55] <roycroft> through late last night the ups website was showing the status of "delivery by the end of the day"
[14:34:02] <roycroft> i stopped believing that around 11pm
[14:34:09] <Rab> Hmm, the CNC Toolkit download link leads to a deleted Google Code project.
[14:34:14] <fragalot> they didn't say what day
[14:34:16] <roycroft> then, this morning, the status was updated to "preparing for delivery"
[14:34:21] <roycroft> they did, fragalot
[14:34:26] <fragalot> prove it
[14:34:50] <roycroft> i assume that this morning they were scooping up as many peices as they could find, stuffing them back into the box, and wrapping the whole thing with a bunch of tape
[14:35:00] <roycroft> the status is now "out for delivery"
[14:35:50] <roycroft> i've never seen a status of "preparing for delivery" before
[14:36:13] <jthornton> maybe that means moving from the wrong truck to the right truck?
[14:36:14] <fragalot> mine typically go from "package announced" to "gone missing"
[14:36:43] <roycroft> possibly
[14:36:56] <roycroft> but i rather fancy the notion that they're trying to reconstruct the package
[14:37:10] <CaptHindsight> I once had a package with status: Left with military guard at station.
[14:37:16] <fragalot> i've had one package that showed up after almost one year
[14:37:18] <CaptHindsight> but I didn't have one
[14:37:19] <roycroft> especially since it's nothing time-sensitive, and if it's damaged i'll be able to get it replaced
[14:37:30] <fragalot> ordered magnets and apparently (according to the delivery guy) they got stuck to the roof and nobody noticed
[14:37:34] <roycroft> you didn't have a guard?
[14:37:58] * roycroft also does not have a military guard
[14:37:59] <CaptHindsight> no guard, no military station
[14:38:13] <roycroft> i don't have a military station either
[14:38:44] <roycroft> i'm not into guns, and things military tend to have a lot of those
[14:38:49] <fragalot> CaptHindsight: did you have a dog? :D
[14:39:38] <CaptHindsight> fragalot: not even a dog, the supervisor was helpful and gave me his cell number and the GPS location of the driver nearby
[14:39:56] <CaptHindsight> met her on the corner a retrieved my parcel
[14:39:59] <roycroft> they got stuck to the roof for a year and nobody noticed?
[14:40:01] <roycroft> that seems unlikely
[14:40:02] <CaptHindsight> a/and
[14:40:34] <fragalot> roycroft: that is what they said...
[14:41:01] <roycroft> in a year, the driver would have entered and exited the vehicle thousands of times
[14:41:14] <roycroft> probably tens of thousands of times
[14:41:27] <roycroft> and not once glanced up at the ceiling, even accidentally?
[14:41:42] -!- trentster has quit [Ping timeout: 246 seconds]
[14:41:55] <fragalot> you're assuming they get the time to do so
[14:41:55] <SpeedEvil> could have been inside a parcel facility
[14:42:16] <fragalot> could be the sorting machine, who knows
[14:42:43] <fragalot> didn't ask details, just laughed and accepted the package
[14:42:54] -!- P1ersson has joined #linuxcnc
[14:43:05] <roycroft> it could be someone at the depot was using it to hold their girly calendar up on the wall for a year
[14:43:12] <fragalot> lol
[14:43:14] <roycroft> and when the calendar ran out they tossed it in the pile to deliver
[14:43:51] <CaptHindsight> sounds plausible
[14:45:45] <CaptHindsight> somebody sent me a subscription to Maxim Magazine or similar a few years ago, I think only half of them ever arrived
[14:45:56] <roycroft> my belated parcel contains, or contained, a bunch of schaller bins
[14:46:31] <CaptHindsight> and the ones that did looked well read
[14:46:38] <roycroft> so if it did spontaneously rupture en route (ups would *never* have mishandled it) there will be a lot of little bins to scoop up
[14:47:13] <CaptHindsight> roycroft: you're just having good luck with your bins
[14:47:31] <roycroft> i hope i like them when finally they arrive
[14:47:39] <roycroft> because all other solutions cost way way more
[14:48:36] <roycroft> i was going to make them out of wood but that would be really bulky
[14:48:50] <roycroft> and would actually cost more than buying the plastic bins from schaller
[14:49:05] <roycroft> not to mention how tedious and time-consuming it would be to make thousands of little wooden bins
[14:49:42] <CaptHindsight> I decided on the formed paper rectangular containers
[14:49:58] <gloops> https://www.pamono.co.uk
[14:50:05] <roycroft> i'd like something a bit more durable than paper
[14:50:06] <gloops> that would look better roycroft
[14:50:17] <CaptHindsight> lowest cost and highest density storage
[14:50:23] <roycroft> i need to be able to pull the out and tote them around
[14:50:37] <roycroft> this is for the shop
[14:50:47] <roycroft> high density is critical
[14:50:58] <roycroft> an apothecary cabinet would not do
[14:51:45] <gloops> look good when customers come round though, old traditional style shop
[14:52:42] <roycroft> when i'm attracting the class of customers who would appreciate that i'll be able to afford a larger shop
[14:55:39] <gloops> at the boatyard near here they used to have a little brick building where customers went, all old hand tools on the wall, old cabinets etc, little stove - really nice, most of the work was done on modern machines round the back
[14:56:29] <CaptHindsight> I just have a front counter with a picture of a magic tree..
[14:57:00] <CaptHindsight> i tell customers that we just leave their parts by the tree in the forest and the elves handle the rest
[14:57:56] <gloops> well, you can only appeal to some of the potential market at once
[14:57:58] <CaptHindsight> and if there is any delay we blame it on haunted parts
[15:03:18] <gloops> 34% of British people believe in ghosts – and 9% have communicated with the dead
[15:03:37] <gloops> probably more likely to believe a ghost excuse than the usual 'van broke down'
[15:04:48] <CaptHindsight> I haven't noticed as much Halloween things this year as others
[15:05:01] <CaptHindsight> maybe since it's a Wednesday
[15:06:05] -!- syyl has quit [Quit: Leaving]
[15:07:55] <Tom_itx> no room for it, it's packed out with christmas already
[15:08:25] <gloops> quiet round here too, all the kids must have grown up and nobody had any more in the meantime
[15:09:39] <roycroft> i think you brits are confusing your mps with ghosts
[15:10:00] <roycroft> which is understandable
[15:10:15] <gloops> ive washed my hands of the entire thing
[15:11:16] * roycroft thinks halloween is the most wretched "holiday" of the year
[15:12:12] <roycroft> little more than a plot by the american dental association to increase business
[15:12:31] <Tom_itx> halmark invented valentines's day
[15:12:46] <roycroft> and an excuse for college students to get drunk and riot
[15:12:52] <gloops> theyve all been commercialised
[15:13:04] -!- dud3_l1n0x has joined #linuxcnc
[15:13:06] <roycroft> i don't know how much of a problem that is elsewhere
[15:13:21] <roycroft> but we have a long, sad history of drunken riots on halloween
[15:13:43] <roycroft> that has in recent years included overturning several police cars, and even the burning of a police car
[15:14:01] <roycroft> massive amounts of property damage in the university district
[15:14:13] <CaptHindsight> we call that Wednesday in Chicago :)
[15:14:32] <roycroft> perhaps not surprising, since animal house was filmed at our university
[15:15:28] <CaptHindsight> pretty quiet around here except for a few pockets on the south and west sides that make national news
[15:17:13] <gloops> i just make a point of mumbling to myself whenever im at the front of the house, they dont bother with me
[15:19:09] <roycroft> fortunately i live on a dead-end street mostly inhabited by empty-nesters
[15:19:30] <roycroft> the parents of the few young children who live on my block know to go elsewhere for the trick or treating
[15:19:59] <roycroft> so not much goes on at halloween on my block

[19:01:49] <roycroft> well, the schaller bins are somewhat disappointing
[19:02:01] <roycroft> they are not at all consistent in size
[19:02:18] <roycroft> which is going to make my storage drawers rather untidy, should i decide to use them

[19:39:34] <roycroft> both, actually
[19:39:38] <roycroft> but mostly the latter
[19:39:57] <roycroft> the height inconsistency is the most annoying thing
[19:40:08] <roycroft> and they are all supposed to be the exact same height - 1.75"
[19:40:22] <roycroft> the heights vary by at least a couple mm
[19:40:45] <roycroft> as far as depth, there are some that are nominally 1.875" deep, and some that are nominally 1.95" deep
[19:40:53] <roycroft> but again, they vary by a mm or two
[19:41:30] <roycroft> i ordered only a handful of the 1.95" deep ones, to see if i could put up with the difference
[19:41:46] <roycroft> the vast majority of bins that i would use are nominally 1.875" deep
[19:42:02] <roycroft> and by "deep" i mean y axis length
[19:42:10] <roycroft> and by "height" z axis length, of course
[19:43:49] <roycroft> they are otherwise very nice bins
[19:44:06] <roycroft> i just don't know if i want to deal with the sloppiness
[19:45:49] <roycroft> if i went with sortimo or tanos bins, and the height was supposed to be 60mm, i'm sure that every one of them would be 60.0mm high
[19:46:03] <roycroft> but sortimo and tanos cost 3-4x as much as schaller
[19:46:32] <roycroft> and i would have to order them from .eu, with shipping being about the same as the price of the bins, so 6-8x as much at the end of the day
[19:48:40] <SpeedEvil> roycroft: sander thicknesser
[19:48:47] <SpeedEvil> or whatever they're called
[19:49:17] <Rab> roycroft, any guess what they're made out of?
[19:52:41] <roycroft> abs, i would guess
[19:53:05] <roycroft> speedevil: i would be purchasing ~2000 or so of them
[19:53:23] <roycroft> rather tedious to dial them all in like that
[19:53:27] <SpeedEvil> roycroft: yes, it wasn't a very serious suggestion, though it would be fast if it diddn't shatter them
[19:54:08] <roycroft> it almost makes me consider making them out of wood, which was my first idea
[19:54:12] <roycroft> it would cost a bit more
[19:54:20] <roycroft> and it would take for fripping ever
[19:54:35] <roycroft> but they would all be consistent in size
[19:55:31] <roycroft> the main reason i decided to look at plastic bins is that the plastic ones have walls that are 1mm or so thick, while realistically i would need to make the walls 6mm thick if i used wood
[19:55:37] <roycroft> and that would waste a lot of space
[19:56:29] <roycroft> and the schaller bins cost less than the cost of the wood
[19:57:04] <roycroft> not to mention the glue, cutter wear, abrasives, finish, and the enormous amount of time required to make them out of wood
[19:57:50] <roycroft> i'll still make a prototype drawer and populate it with the schaller bins before i decide what i'm going to do
[20:00:13] <jdh> buy 100 3d printers, print the bins
[20:03:30] -!- ziper has quit [Ping timeout: 264 seconds]
[20:08:27] <roycroft> then they would look like ugly 3d-printed bins
[20:10:01] <roycroft> but potentially very consistent, ugly 3d-printed bins
[20:14:40] <CaptHindsight> make a mold, cast with resin in minutes
[20:16:23] -!- gloops has quit [Ping timeout: 244 seconds]
[20:18:52] <roycroft> lather, rinse, repeat 3000x
[20:18:54] <CaptHindsight> 20Kg polyester resin ~$11/Kg
[20:19:07] <CaptHindsight> make the mold 16 up
[20:19:24] <roycroft> here's the deal
[20:19:38] <CaptHindsight> 3000 / 16 = 188 times :)
[20:19:41] <roycroft> my goal is not to learn how to make hardware storage bins
[20:19:48] <roycroft> my goal is to organize my hardware in bins
[20:20:08] -!- gloops has joined #linuxcnc
[20:20:59] <jdh> you probably wouldn't care for the 'machine them out of billet' idea either then.
[20:21:13] <roycroft> no, probably not
[20:21:31] <roycroft> nor making them out of carbon fiber and resin
[20:21:45] <CaptHindsight> sand pattern at the beach, pour aluminum
[20:21:48] <roycroft> nor forging them
[20:22:18] <Rab> Waterjet stainless sheet, brake and spot-weld!
[20:22:45] <jdh> draw them
[20:23:04] <CaptHindsight> nah 1.75" steel strip notched every 2 inches
[20:23:24] <andypugh> I tried printing some lathe soft-jaws last night. Worked perfectly, apart from me getting the hole size wrong, the T-slot width wrong and the serration depth wrong in two different ways.
[20:23:25] <CaptHindsight> cut and assemble into arrays
[20:23:47] <andypugh> I was about to just modify subtractively until big isue 3

[20:25:59] <CaptHindsight> https://www.colonialscientific.com
[20:27:30] <roycroft> i need individual bins
[20:27:34] <CaptHindsight> nahh probably something wrong wit those as well
[20:28:20] <roycroft> typically when i'm working on a project i'll go grab the drawers holding the fasteners i'll need and set them on a bench near where i'm working
[20:28:32] <roycroft> i don't run back to the storage cabinets every time i need a fastener
[20:28:37] <andypugh> It’s hard to make parts from the same batch and the same tooling vary.
[20:28:55] <roycroft> yet they do
[20:29:09] <roycroft> primarily in height
[20:29:25] <roycroft> and it's obvious that they're sheared off after being ejected from the mold
[20:29:41] <roycroft> so i'm assuming there's a process flaw in that part of the production line
[20:30:12] <gloops> youll only get variation if you try not to
[20:30:19] <andypugh> 3DP lathe jaws: https://photos.app.goo.gl
[20:30:31] <roycroft> germans can make bins that are consistent in all dimensions
[20:30:34] <roycroft> why can't new englanders?
[20:30:59] <gloops> new englanders have lives maybe?
[20:31:29] <roycroft> lives that are paid for by their performing work
[20:31:58] <roycroft> honestly, these things look more like they were made in china (20 years ago) than in massachusettes
[20:32:09] <roycroft> but they do not have the sweet smell of china
[20:32:21] <roycroft> so i don't have to worry about offgassing them for a month before i can bring them into the shop
[20:32:37] <Rab> roycroft, the chinese contract manufacturer has some child laborer standing there with a box cutter, and they're doing their level best.
[20:32:52] <roycroft> box cutter?
[20:32:54] <roycroft> those things cost money
[20:33:01] <roycroft> i thought they used broken pieces of glass
[20:33:17] <Rab> Teeth and fingernails
[20:34:08] <gloops> they still trim rubber parts with scissors here so far as i know, few people at a bench trimming grommets and o rings, thousands and thousands a day
[20:36:24] <roycroft> peasant women in spain still pick crocus threads by hand
[20:36:29] <roycroft> they get 30mg or so per flower
[20:36:50] <gloops> no machine for that...yet
[20:36:52] <roycroft> some stuff is hard to automate

[20:38:12] <andypugh> 30mg of safron, though, is valuable
[20:38:42] <roycroft> and delicious!
[20:39:00] -!- phiscribe has joined #linuxcnc
[20:39:18] <roycroft> one just cannot make paella properly without it
[20:39:19] <MarcelineVQ> and contains about 2mg of safron
[20:39:43] <roycroft> it just doesn't taste right
[20:40:39] <andypugh> $1000 / kg. So 30mg is ¢2
[20:40:47] <andypugh> Err. ¢3
[20:41:00] <roycroft> plus vat
[20:41:23] <roycroft> except not here
[20:42:08] <gloops> About 200-500 stigmas make up a single gram of saffron, and usually there are only three per flower.
[20:42:09] <roycroft> we have stupid tax, er, tariffs, here instead
[20:42:24] <andypugh> Pick 1 30mg in 10 seconds, $10 per hour. it money, but I prefer my job.
[20:42:55] <gloops> i bet they hate flowers
[20:43:12] <andypugh> I bet the flowers hate them back :-)
[20:43:19] <roycroft> if $1k/kg is the retail price then the worker is going to make about 1/10 that
[20:43:42] <roycroft> now it's $1/hour
[20:43:46] <roycroft> for some very hard work
[20:43:54] <andypugh> But I bet they can do better than 10 seconds per flower
[20:44:03] <roycroft> sure
[20:44:06] <roycroft> now they're working even harder
[20:44:21] <andypugh> Sucks to be dumb :-)
[20:44:26] <roycroft> nobody ever got rich picking saffron
[20:44:37] <roycroft> or lacking in opportunity
[20:45:10] <andypugh> Yes. Stop being reasonable on the Internet!
[20:45:54] <gloops> i dunno, its that kind of work where they talk while theyre working, probably dont even notice they are working, its just a day chatting
[20:46:18] <MarcelineVQ> You can't talk around flowers gloops, they get jelous and shrivel up
[20:46:36] <MarcelineVQ> You talk to houseplants, they're quite lonely
[20:47:06] <gloops> i think there have been studies that show they respond positively
[20:47:33] <roycroft> it depends on large part on what you say to them, i should think
[20:47:57] <andypugh> I suspect confounding factors, like noticing that the flower you are talking to needs watering.
[20:48:09] <MarcelineVQ> there's a response but I haven't seen a reputable strudy that has determined what is happening, whether it's vibration from the sound, warmth, carbon dioxide from breathe, moisture from breathe
[20:48:59] <roycroft> well, say nice things to them

[21:05:42] <andypugh> I could parse that 40 years ago…
[21:06:55] <andypugh> I did read ∃ as “there exists” so it hasn’t all dropped out of my head through disuse.
[21:07:29] <MarcelineVQ> It's mostly nonsense I just wanted an excuse to try my new unicode plugin
[21:07:42] <andypugh> :-)
[21:08:16] <MarcelineVQ> that there exists a person who is a Vegetable does not mean for all vegetables which are Vegetables there's some person implied

[21:10:23] <MarcelineVQ> idk, it's just sillyness :>
[21:10:31] <_unreal_> has anyone used an PRI or asus tinker board with linuxcnc?
[21:11:14] <andypugh> I have read the word “tinker” and most of what I read is LinuxCNC
[21:11:25] <andypugh> So, maybe
[21:14:30] <{HD}> Any linux genius here: “settings-mouse” sensitivity doesn’t appear to be effecting my mouse. I saw something about “xinput” but cannot get it to slow down! My mouse is so fast!
[21:16:28] <MarcelineVQ> Does your mouse itself have a button on it that affects its resolution?
[21:17:12] <{HD}> MarcelineVQ: not this one but I believe it is “high dpi” or whatever it is called.
[21:37:44] <pcw_home> _unreal_: I have had LinuxCNC master running on a RPI for about 3 months now, very stable if a bit slow
[21:38:24] <andypugh> Ah. I had no idea what an RPI was :-)
[21:38:56] <andypugh> Sorry, I made the same typo. “PRI” puzzled me.
[21:39:26] <{HD}> pcw_home: are you using the gpio for pulse gen?
[21:39:30] <pcw_home> I guessed thats what he meant from the tinker relation
[21:39:36] <pcw_home> no, FPGA
[21:40:42] <{HD}> pcw_home: Neat. You should do a write up on that.
[21:41:17] <pcw_home> Its using a supported driver ( hm2_rspi )
