disco lighting

Posted on Mar 26, 2013

This project is intended for controlling mains powered disco lighting, although there are many other possible uses for controlling almost any mains appliance. It will control five seperate channels at up to 3 Amp per channel. This could be increased by designing another PCB with wider tracks than the PCB included with this design. I could have used relays to control my lights, but triacs seemed like a more sensible solution as they react quicker and are totally silent as they contain no mechanical parts.

The low voltage control side and the mains side are totally isolated, as opto-couplers are used to fire the triacs. I have not included any schematics as this project is very simple, expecially due to the fact I have included a PCB. Notes: There isn&#
