My project has finally come to an end! There are improvements that can be made but i'm happy with how it turned out so far.
A huge thank you to everyone on this forum who helped me along the way—this project wouldn't have been possible without your support.
A short summary:
- I have kept from the original instrument only the power supply, and the power amplifier.
- I have made a circuit with shift registers to read the keys.
- I have made a simple mixer with line output.
- An STM32H723 generates the organ sound.
- An STMF411 generates the percussion sound.
- The microcontrollers are powered by a 3.3 step-down converter.
I just recorded the only song I know how to play. Check out the result here:
