From the project
DIY analog modular synth
- Get to know delicious circuits (experimenting a lot) - Use them in crude ways to generate sounds - Learn how to design circuits & professionally manufacture them with KiCad - Learn whats possible with analog circuits and what's not - Have a lot of fun without the need of programming
- Get an overview of electronic parts out there - Manage a big project - Make ambient dub techno at the end lol

PSU: common questions
How big is the PSU PCB?
The PSU measures 350 × 50 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the PSU?
45 components, from 17 distinct parts. The full bill of materials is listed on this page.
Where can I download the PSU design files?
From the carl-becker/fusion-core repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the PSU design in my own project?
The repository has no license, so all rights stay with carl-becker. Use it as a reference, and ask the author before reusing the design.
