Oh, and they don't mention the extra fees from the scam company until after they've charged you the €140.

We were planning to go to EMF camp, but the UK wants €140 for a single-use visa for my partner, and then they require her to pay an additional €93 to a scam company that tries to sell her data, just to process her documents.

13cm of too-close track spacing is all it takes to get some nice crosstalk

Definitely don't use this to make perf boards with slightly incorrect spacings, and send them to your enemies ;-)

Working on some examples of basic PCB things you can make with CircuitPainter- here's a command line perf board generator: https://github.com/Blinkinlabs/circuitpainter/blob/main/examples/perfboard.py

@phooky We should have stopped with the turbo encabulator

@buspirate If it's just for ID, maybe a dirt cheap OTP micro like the Padauk PMS150C-U06 ?

@buspirate Soon you'll need to put little ID chips on each of the breakout boards, so that the bus pirate can identify the automatically ;-)

@buspirate There shouldn't be any difference- it's set by that variable, which is pulled from the board profile by default. Feel free to bring a board by if you want to measure the clock tuning.

@buspirate How well characterized are the tuning caps on your xtal? We had boards that wouldn't boot due to what we thought was a firmware problem, but it turned out that the RP2040 SDK has an extremely short timeout for crystal startup. Changing that was a quick software fix: https://www.dropbox.com/s/bcwjz9dnmoshg4h/2023-08-22%20blinkypendant%20startup%20issue.pdf?dl=0

@quixoticgeek Next time I hope they upgrade to a 300mm process

We designed a stencil placement jig for large, high-density solderpaste application. The boards are half a meter long, with 0402 and QFN parts along them. Got through the whole prototype run with zero defects!

@phooky Glad you're ok!

@artelse Thanks! The secret was using the SLA printer to make alignment troughs to fit the pogo pins in. Here's what the completed setup looked like
