Foehn - DTDP relay module

Relayboard is still in development and is meant for an interactive art installation.

This is a custom DTDP relay module to control an array of vortex cannons. 

The relais will switch between two circuits. One circuit is providing audio and the other is charging capacitors. Both circuits go towards one output and that is a speaker with a cone attached to it. With a microcontroller I will tell the system to alternate between audio and vortex rings. The reason this module is needed is because I will be controller a big array of speakers.
