I implemented automated export of production files, PDF exports and rendering of my KiCad template in github CI.

Got sidetracked and designed an ADC that's just a chain of OpAmps and resistors that basically do successive approximation.
There is no feedback / only feed forward and the settling time is determined by the propagation delay of the Amps together with the passives. This results in some glitching at the zero crossing, to gating with registers might be needed.
It can be scaled to arbitrary bit depth and might be interesting for #ModularSynthesizers.
I brought #chubby75 I/O mod PCBs to #37c3
If you want to turn your #Colorlight75 into a general purpose #FPGA platform, drop me a DM.

I finally got around to do some programming on a GUI tool that I had on the farthest back burner and essentially was just an idea until now.
It requires a node editor. I just squished most bugs and implemented snap to grid, which makes it like 23% more satisfying to use.
I implemented automatic PDF and Gerber export from KiCad with Make, Python and Poppler in my KiCad template repo.
There also is a git hook that can run this automatically.

For the #ChubbyHat I also added automatic creation of the PCB art with OpenSCAD.

Jup. Adding 180 Ohms and flipping the bus for the v8 connector did the trick.
Which is good, cause I already soldered the QT Py 2040 to the board ^^
