  • Audio (will drive headphones or other synthesizers)


The Build

Scott from Division 6 will walk you through building and testing the oscillator kit.  All parts and tools will be provided.

The kit isn’t a very complicated build.  It’s a little small/packed, but if you’ve ever soldered anything before you shouldn’t have too much problem.  Even if you have never soldered before, there will be some stunt boards available to practice on first.

This build is for both adults and kids who can safely wield a soldering iron.

To Sign Up

Just purchase the kit from this page, then show up to the Knobcon solder lounge at the designated time on Sunday.  Your kit will be there waiting for you.
