@kicad_pcb 3d render turning into a real thing. Nomad Guitar Project: the small board holds the DSP+wireless (ESP32-P4), power converters and talks via SPI to the @Infineon PSoC5lp doing all the cap sense controls, midi, DACs for analog VCF etc.

@Suleiman2_ktoPL Sorry za późną odpowiedź. O! to był taki eskperyment, gdzieś koło 2004 roku, istnieje tylko 1 szt.

Working on a futuristic/cyberpunk guitar packed with electronics. As always using my favourite duet of @FreeCADNews and @kicad_pcb for the design.

@FreeCADNews @kicad_pcb Pickguard / Touch+Led+Midi controller / a bit of analog circuitry and lots of connectors. PCBs manufactured by @JLCPCB as always turned out great!

New project in the works: Stereo IR cabinet emulator + Reverb running on Teensy4.0. Designed using @kicad_pcb and @FreeCADNews

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

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.
