From the project
This is the repository for the Research and Development, Production, and assembly of the Electric Guitar MK1.
- DIY portable electric guitar with integrated digital effects and modular power/audio system - Final version features Teensy 4.0, onboard FX, rotary encoder UI, OLED display, amp/speaker output, battery or DC power, and RGB lighting - Entire build: woodwork, PCBs, 3D prints, firmware, and more - Early prototype (Mk0) failed due to poor electrical design and overcomplex hardware, rebuilt from scratch over 12+ months with newly acquired engineering and fabrication skills
