Custom synth enclosure – Part 1
With the main modular audio chain assembled, and (almost) playable from a 37-key piano keybed, I started to turn my attention to designing an enclosure to hold all the components of the synth together…

Dual ±12V 48W linear power supply from single-sided DC input
My Eurorack-compatible synth project requires a ±12V power supply. I also wanted to use an external “power brick”-style AC-DC converter to handle the mains power. I developed my own secondary DC-DC power supply with two LDOs, a Ćuk inverting regulator, and a power distribution bus to clean up the output of the power brick and generate the dual-sided power supply required by the rest of the system.
The GS-101 analog synthesizer project
Ironically, since I’ve spent so much time working on this project, I have not posted about it much—but I’ve spent a huge amount of my free time in the past two years or so building a complete analog synthesizer. From scratch. And now it’s really starting to come together!
Audio hardware Development Breakout Board
Over the past year I’ve gotten into building modular synth components. There’s a lot more to share on that front; I’ve put together several modules and have a plan for several more to go into an integrated system. The relative complexity means there’s a lot to write about, though, which has made me keep putting it off…
In the meantime, I completed a smaller project this weekend—a breakout board that makes it easier to develop audio circuitry on a breadboard.
