Do you have a BOM for the project and a total cost? I looked at several of these types of lights when i was planning the lighting for my wedding and it would be interesting to see how your cost compares to the commercial stuff?
What LEDs did you use, getting a good colour spectrum, true white and equal dispersion is what ups the price tag on the high end units
I'd also be interested to see your schematic as i wonder how robust / stable it is for long run times.
The LEDs are 3W TRI Colour. It's a module from a company called L&A. The module costed 160€. I don't have a BOM sorry, but the total cost is around 350 - 400€. Here some photos of the circuit boards:
Certainly looks like a pretty ambitious and well executed project. We're all technical on this forum, so we'd be interested in seeing whatever you're willing to share - parts, schematics, algorithms, listings, block diagrams, the lot!
