Code and schematics for my DIY modular synthesizer
This is a power supply designed for use with a modular Eurorack synthesizer system. It is designed to deliver high power with low noise, while maintaining a commpact form factor.
WARNING: this is an advanced project. Do not attempt this without a basic knowledge of electronics and through-hole soldering. I take no responsibility for my supply blowing up your expensive gear. I am doing this for fun and for free, and am liable to make mistakes. However, I have been using this supply with my system for over a month now, and have had no issues so far.
