Ten Volt Light Chaser

A MSP430 based, four channel light chaser for ten volt controlled lighting fixtures.

My friend has a four channel phase angle dimmer pack but no real way to control it. He'd like to use it for band shows but not have to babysit the board of switches he has rigged up. This project will let him attach a programmable chaser to the input of the dimmer pack and get on with doing other things.

The circuit works by bumping a ten volt signal from any analog light control interface in an arbitrary pattern, programmed with pushbuttons on the board. An MSP430G2221 controls the patterns and interface.

The onboard ten volt regulator (a humble LM317) allows this board to be used without another analog controller in the system.

    I managed to get the programming routines written and worked out. The only thing left to do now is finish the 10v circuitry and button it all up.
