For GAVO lighting I made two PCBs for both the supply and the head of the light. The GAVO light is a plasma light which produces a very bright and pure light that’s great for lots of things, but is targeted at lighting sets, specifically high speed shoots.
The supply side consists of:
- A DMX receiving unit
- A user interface with four dual LED light buttons and a backlit LCD
- It communicates with a Magnetron driver over RS232
The head includes:
- Motor control with feedback from an optical sensor
- Fan control
- Temperature measurement
The head and supply communicate with each other via a custom data over DC power protocol that I developed for the project.
Both boards were built around a Atmel AVR microprocessors, to aid developement I wrote a C library for the project.
