Welcome to Telmatronics

Hello! This is the home of Groovetube, an experimental plasma synth that makes sound in a fluorescent tube.
The first small batch of machines is now finally being built up. We're also in preparation for developing our own plasma tubes - watch this space, things are starting to move!

The Story
The Telmatronics project started with the idea to use plasma for an audio component that could be controlled with a magnet. Other devices like effects pedals use plasma noise, but we wanted a larger plasma that could be directly interacted with.

Experiments with fluorescent tubes and an RF oscillator made some pretty wild and funny sounds, and controlling them with a magnet was a lot of fun. So we ran a Kickstarter project with a prototype machine, and then set out to turn it into a synthesiser. 

We've ended up with a lively and acoustic-sounding electronic instrument - you can read more about this and see recent demos on our Groovetube page.

This was designed as a machine to put random fluorescent tubes in, to see what sounds they made, but with fluorescents being discontinued we're having to think again. We've started to prototype a few plasma tubes, and are currently getting ready to run a proper R&D program. Using custom electrodes should let us design for different types of sound - exciting prospects!
