00:48 <eddyb> aww, I was on some random Romanian "electronics projects" website (ardunio & friends, robotics, 3D printers, etc.), for an unrelated reason, and I started browsing their misc products, and: https://www.optimusdigital.ro/ro/altele/5720-testclip-cu-fir-mama-10p-rou.html

00:48 <eddyb> only 4€, but it's out of stock :(

00:49 <eddyb> (they do have individual clips, but they look like they require soldering, which probably means I would have to waste a bunch of time getting individual pin headers onto each of them or something)

00:50 <eddyb> oh lmao, out of the 3 colors, yellow is in stock https://www.optimusdigital.ro/ro/altele/5729-testclip-cu-fir-mama-10p-galben.html

02:40 <d1b2> <Hardkrash> @Attie @electronic_eel I tend to prefer the internal tooth lock washers e.g. https://www.mcmaster.com/93925A416 As the locking elements are contained inside of the screw head and affect a smaller area.

02:54 <d1b2> <Hardkrash> if you want to really protect the PCB then a Copper washer soldered to the mounting hole pad is the best protection, but that gets up in the complexity that is typically not warranted. i.e. threaded screw bosses and standoffs. Some times the anodization shop can use one of the mounting holes as the mount for the hanger and it will block the anodization from sticking. They also typically have plugs that can be placed in the holes that will prevent

02:54 <d1b2> plating as well.

02:59 <d1b2> <Hardkrash> Some conductive fabric/mesh can be used as a washer and it can break through the thin aluminum oxide layer, but not anodization. https://www.laird.com/products/electromagnetic-interference-emi-shielding/wire-mesh-knitted-conductive-gaskets/electroground-washer/89xx-xxxx-44

03:01 <d1b2> <Hardkrash> For the standoffs i'm talking about, here are some that are threaded. https://www.adafruit.com/product/4206

03:02 <d1b2> <Hardkrash> Others with clearance holes are available.

03:05 <d1b2> <theorbtwo> I should think if you want to not have anodizing on a threaded bit, you'd give it to the anodization shop with a screw threaded into it, no?

03:08 <d1b2> <theorbtwo> Ah. Short answer, probably not: https://metalfinishingsltd.co.uk/articles/non-aluminium-inserts-and-anodising/ -- steel screws won't do what you want, as they would be converted to rust. You want hdpe, polyprop, cpvc, or ptfe screws.

03:10 <d1b2> <Hardkrash> yea, didn't know about the rusting in place, but little rubber plugs are typical, as easier to insert and remove.

03:10 <d1b2> <Hardkrash> https://www.aeanodizing.com/masking-and-plugging/

03:11 <d1b2> <Hardkrash> Yikes, this is a huge variation of designs. https://viadon.com/products/caps-plugs-and-corks

06:49 <LorenzoB> Are third parties allowed to make and sell the glasgow?

06:56 <sorear> yes

09:52 <eddyb> I recall something about serial numbers and an authentication chip, to be able to validate a certain manufacturer/production run, so if that's still a thing, presumably you'd have two levels of third party devices (and support for them, presumably?)

10:38 <bvernoux> I have just seen https://www.crowdsupply.com/1bitsquared/glasgow/updates/campaign-is-now-live

10:39 <bvernoux> Just one word about comparison with HydraBus the price is not 80euros but 69euros (Amazon)

10:40 <bvernoux> also HydraBus does support CLI and API (pyHydraBus see https://pypi.org/project/pyHydrabus) and support also parallel (Sump with 16bits)

10:40 <d1b2> <uep> hey, these look cool and useful to keep in mind. I'm a big fan of using rivnuts for mounting to sheetmetal caases

10:41 <bvernoux> it will have been interesting to add number of protocol supported for each platform too

11:59 <eddyb> okay, order sent, found a bunch of random useful things on that website, but the main thing for the glasgow are those grabbers. hopefully they'll be good enough to get me started

12:35 <bvernoux> eddyb, good grabber are expensive

12:36 <bvernoux> EZHook are good for the price

12:36 <bvernoux> compared to that crap sold on Aliexpress ...

12:36 <bvernoux> you cannot grab anything with ultra cheap chinese grabber

12:39 <bvernoux> such micro hook => https://e-z-hook.com/test-hooks/micro-hook/xkm-micro-test-hook-double-gripper-with-0-025-in-square-pins/

12:39 <bvernoux> are very good for the price

12:46 <eddyb> shrug these were $5 for 10, and is local, so I'll find out what they're like in less than a month https://www.optimusdigital.ro/ro/altele/5729-testclip-cu-fir-mama-10p-galben.html

12:47 <eddyb> *and the shop is local

14:18 <d1b2> <HardWall> Hah, @eddyb nice to see someone from Romania here. I have some similar testclips(just tesclips) I bought from AliExpress but they're... not so great.

14:20 <d1b2> <HardWall> I have also some tesclips that came with a DSLogic logic analyzer and those are much nicer and find myself reaching for them much more often.

14:21 <d1b2> <HardWall> Not sure if they are ezhook or what, and don't have them on hand, but nice, nontheless.

14:22 <d1b2> <HardWall> Let us know how they turn out, I might get a set as well, to feed my HW fetish.

14:34 <d1b2> <HardWall> Regarding test probes, i keep wanting to build this thing: https://www.thingiverse.com/thing:3615910 - supposedly, it works quite well.

14:40 <eddyb> heh, that looks like a DIY alternative to https://sensepeek.com/pcbite_20

16:14 <d1b2> <Sid> I have one of those, printed by the designer since I don't have a 3D printer. It works well, takes some practice to get set up to probe a PCB, but is stable once that is done.

16:42 <kmc> neat

16:42 <kmc> I'm getting a 3D printer in Feb, maybe I'll make one

16:54 <whitequark> eddyb: we got rid of that authentication chip

16:56 <eddyb> ah, my bad

17:26 <d1b2> <HardWall> Would that be the ATECC508 or whatever chip? It got removed?

17:26 <whitequark> yes, ATECC

17:44 <d1b2> <Attie> it also want present on the batch I produced (cc @eddyb )

20:50 <bvernoux> d1b2, woo the PCB nano probes on thingiverse seems amazing I have already the PCBite stuff (200MHz Probes + LA Probes)

20:51 <bvernoux> the SensePeek are amazing too ;)

22:26 <d1b2> <martinr> is there a known issue about the scl/sda testpads being mislabelled on revC1?

22:27 <d1b2> <martinr> scl on the back seems to be connected to whats marked as sda on the front

22:27 <d1b2> <martinr> and vice versa

22:56 <whitequark> marcan: ping re README
