508: Loop Detected designs & builds analog video synthesizers for installations, performances, experimentation & fun. We are heavily indebted to the work of Jonas Bers, particularly his CHA/V project.

Our flagship design is the ec500 analog video synthesis system. PCBs, full kits, and fully built systems can be found in our online shop.

More recently, we have also been designing and building Eurorack-format analog audio synthesizers. Check out the Bounce Sequencer system in the online shop.

Schematics, PCB layouts & other collateral can be found at our github.

Designs are open & licensed for noncommercial use. Folks wishing to incorporate our designs into commercial products should contact ross@rossgrady.org. We can probably reach a simple friendly agreement.
