A very quick VCO/VCA build from Tesseract Modular. All surface mount except for the controls and LEDs, but all the surface mount has been pre-soldered. Means that the build is super fast, like 10-20 minutes for most folks.
Sounds really good and has interesting controls, recommended.

Radioactive build and demo


But is it really radioactive? I mean...a couple of my studio devices are, sooooooo...


I have not brought my geiger near it yet (it's in a drawer upstairs) to confirm or deny the presence of actual nuclear decay, sorry. I'll add that step to my test/demo section in the future....
