Someone is unhappy that DigiKey did not ship us any cat food.

The SPI flash adapter boards for @buspirate Bus Pirate are up in our shop: https://shop.blinkinlabs.com/collections/development-tools/products/bus-pirate-spi-flash-adapter-bundle

Rasberry Pi Pico/RP2040 protip: Use sideset pins to visualize when different PIO instructions run.

I had a neat aliasing bug where I was sampling a signal much too slowly. The routine worked fine when receiving a signal generated from a completely different device, but not at all when generated by a device that was the same clock frequency as the receiver. With the sideset pins I was able to very clearly see when the sampling happened, and diagnose the problem.

Well, looks like this PI filter does an excellent job of resonating at 25KHz :-/

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

Happy #caturday

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
