I’m trying to find a mod for my spirit life-size pack which will change the cyclotron light colors to match what the wand is set to like in the video game.(Blue-Dark Matter Gen, Green-Slime Blower etc.) Any mods or kits that anyone can recommend?
Both GPStar and Ninjatunes (not the Hasbro-designed Ninjatunes, the DIY Ninjatunes) can accomplish that.
GPStar is open source, and you can use that open source software in your own Arduino Mega 2560 if you want to make your own hardware rather than buy prebuilt boards.
Disclaimer: I write software for GPStar, so I am not an unbiased observer.
