disco synth, STM32 Discovery enclosure
thingiverse
The STM32F4 Discovery with it's FPU, audio DAC and headphone amplifier is a great board for making high quality sounds. But with a single user button, it lacks of inputs. I added a simple home-made front-end pcb with 5 pots and 3 switches that allows you to change sounds in real time like an analog synthesiser. You control envelope ADSR, harmonics, pitch, vibrato, tempo, ... The whole stuf needed a box, so i made this one, "à la" Aplle II.
