My Adelaide coasters arrived! I'm super happy with the PCB, it came out beautifully.

Designing my first PCB in Kicad. I think I've got the power supply wired up correctly.
Helpful JLCPCB tariff faq. Incredibly depressing. Pretty much prices out most of my Tindie things. https://jlcpcb.com/help/article/us-tariff-policy-faq #pcb #pcba #jlcpcb #tariff

Looking for a printed circuit board (#PCB) designer/artist who takes #commissions ! We're designing a simple, but interesting kit for our grand opening in June!
Please retoot/boost for exposure!
I build #circuits to drive projects, like a kiln controller or a robot. My prototypes are built with bought modules on #veroboard. A module takes Vin and GND, and provides IO as SPI, I²C, 0-5v, etc, so I can ignore the specifics of each chip and work on the fun integration stuff.
The problem arrives when I want to make a #PCB without modules. I then I have to open a million datasheets and spend a week finding components and routing stuff.

New PCBs from #jlcpcb . First time doing hot plate soldering, only had to fix one solder bridge! so much easier than using an iron on these 0.5mm pin pitch parts.
Of course it doesn't work 
I got the connector pins backwards... Luckily they make a reversed connector so these boards don't go into trash, just have to wait for new parts!
I just finished my first attempt at a design for a schematic for an MCU (STM32N657Z0H3QTR).
Malware is a model designed to correct other malfunctioning robots. He was intended to infect and commandeer their operating systems, and ultimately force a fresh reinstall.
But Malware finds these units to be delightfully unique rather than broken. Instead of hacking into buggy bots to change them, he acts as a sort of guardian, identifying and patching their vulnerabilities so they can secretly carry on as they are. Some systems may indeed wind up prey to Malware's viruses, however - databases tracking buggy bots go offline now and then, and suspicion is growing around whether this model is functioning as intended.
This sticker sheet and the corresponding pin design are still available in the Short Circuit pre-order store - you can still get in on the initial fulfillment until surveys and the store close!
I need a momentary button switch (a reset button) that can solder into one of these through-hole pairs, more often used for jumper pins. I can't find any with simply through pins - such buttons always have the rounded fin connectors with an in-bored hole.
Anyone know where I can find such a button? Thanks.

@3dprinting I just posted this PCB to r/PrintedCircuitBoard. I'll see what kind of suggestions I get.

When a #PCB board designer, manufacturer and seller offers a #3D file of a board and all its measurements are off grid from the real one... 
I'm looking at #Waveshare!
What do you think how I should design a fitting case for it? Tons of test prints and wasted filament? Damn... 
I recently saw a video where someone was making DIY PCBs with what's essentially a miniature cnc shaper, using a lathe bit as the cutter. I can't find it now. Anyone know where I can find the video, or did I dream it up? #pcb #maker #cnc #electronics
Holy shit, the PCB design of this new sensor board, called Ophanim, of CERN’s Aegis experiment just fucking slaps. Right now, there don’t seem to be many images of it on the web, but I hope to see more in the future.
Continued thread
About that BusBoard Prototype Systems SB4 board -- they're expensive. They're more than $6 each (Canadian) plus shipping from DigiKey. They're $10 each plus shipping from Mouser.
That's a lot for a hobbyist when you're experimenting, especially if you're making mistakes.
I looked around again recently, and couldn't find anything I liked at a reasonable price point.
So what does one do in this situation? Well, if you go Overkill 9000, you design your own prototyping perfboard and have a bunch manufactured for you! When you design your own, you can give it any features you like. So this one has:
18 x 36 (648 holes total)
It's two 18 x 18 sections, though I didn't have them scored for snapping.
A total of 6 horizontal busses in groups of 2, at the top and bottom plus one in the middle.
3 sets of 2 vertical busses within that space between horizontal bus sets, similarly edge - center - edge.
Then each row has a 6-hole pad on each side of the center 2 busses, which are spaced for IC or other standard 0.4" component layout.
Made of proper FR4 fiberglass. Good copper, good soldermask.
Silkscreened row and column IDs on both the front and back, at both the start and end of each row/column (and they match up with the back...).
And silkscreened boxes on the front showing the pad/buss pattern - no more flipping!
They arrived today and ... they're beautiful.

First Look at the Bare Liberux Nexx PCBs
Our redesigned prototypes have arrived completely bare! These are the raw PCBs, fresh from manufacturing, before any components are assembled.
It’s been a long wait, but they’re finally in the hands of our assembler! Now, we’re excited for the next step: having them fully assembled in our hands. 
Stay tuned for more updates as we bring Liberux Nexx to life!

Those PCBs were manufactured by PCBWay (who kindly offered to sponsor this project), and I definitely have nothing to complain about: the ordering process was as easy as it gets (upload Gerber files, select features and place order), build time was 3-4 days as expected and the quality and finish are excellent! 
Overall everything went absolutely smoothly, so I'd suggest you checkout their website next time you'll need built-to-order PCBs: https://www.pcbway.com/

I got the "Amp Switcher" PCBs in the mail a few days ago 
As I plan on building both a 6-way and a 2-way switcher, I ordered boards (5 of each) for the larger size only. The "relays array" board is 2oz copper and has a slightly different color.
The photos also show a "control matrix" board resized to 2-way switching (bottom right); this is easily done by hand using brute force, although I suggest using pliers to ensure it's all cleanly cut.
What’s this chip , any ideas #electronic #pcb #chip #eletronicsengineering #hardwarehacking
