After my last photoshoot with a model I realized that it’d be pretty convenient to have an RGB lightstick for various scenes. Same could be accomplished with an off-camera flash plus color gels, but it seems that it’s simpler with a lightstick and using an off-camera flash has it’s other uses and nuances compared.
Additionally I also wanted to use the lightstick as a sort of mood light for parties with friends and maybe at home, so the LED strip should be addressable to support various effects just for that extra coolness :)
For just photography there are dozens of commercial products available, of course, if you are ready to pay 200+€ for something PRO which is as simple and I didn’t want to order cheap-o sticks from China either in fear that they would actually suck and be very basic.
Having that in mind, I set out to gather ideas how this could be done without spending too many hours on the software side. I figured that this should be a common project… however like I learned with the airsoft bomb project – common doesn’t mean usable. There were many projects related but all the code I found was so horrible that ultimately I wrote my own in a few months period.
