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
