Computer controlled disco and theatre light project

I am currently working on an 8-way computer controlled disco / theatre light project. The controller works either as a standalone unit or in conjunction with a computer to provide complete controller over the lighting sequences.

The project uses low voltage (12v) Par16 cans to reduce the risks associated with mains voltage electricity. Domestic lighting transformers are used to provide high light power output (max 50w per channel, 400w max).

The project was going well until my bridge rectifier exploded with a flash of light and a small bank and bit of smoke. I believe this may have been due to a short circuit, perhaps in the cable going to the Arduino. I've now replaced the bridge rectifier and bypassed the damage to the stripboard.

Status so far

Regulated power supply - done - fixed
Case design and build - partially complete
Triac driver module - one bank complete, one to make
Mode selection -
LED mode selection indicator -
Sound to light module -
Light cabling - 1 of eight made up
Gel colour filters - done
Arduino sketch program code - test sketch only
Computer controlled software -
