Working on a futuristic/cyberpunk guitar packed with electronics. As always using my favourite duet of @FreeCADNews and @kicad_pcb for the design.
Pickguard / Touch+Led+Midi controller / a bit of analog circuitry and lots of connectors. PCBs manufactured by @JLCPCB as always turned out great!

Made a simple calculator for the @Voultar's DIY PCB/Flux cleaner mixture.

New project in the works: Stereo IR cabinet emulator + Reverb running on Teensy4.0. Designed using @kicad_pcb and @FreeCADNews
GUI still needs more work, testing if everything fits into the box as planned. Measured current consumption: about 217mA from a 9VDC source with Teensy4.1@600MHz + ESP32S3 driving the 3,5" display.
High gain guitar sounds works really well as ADC/DAC testing application. Here is a 24bit ADC/DAC codec (WM8731) vs separate 32bit AK5552 ADC + AK4452 DAC

This was a side project i had going on for awhile: a complete starter @PlatformIO_Org project for the ESP32-2432S028 display board, aka Cheap Yellow Display. Also a few useful hardware upgrades.

Recycling time: small charger+protection board for the vape Li-Po batteries. Works also as protection board if charger is not needed.
INA228 + CH32V003 precise Voltage/Current/Power meter almost finished. Only a few firmware tweaks left. Runs on average 6.3mA. Only 2 small bodges in the PCB rev. 1.
