I had a friend ask me me on doing a little pixel setup for him in his window. All he wants is a few of the rgb milky stars that ray sells hooked up to a controller and just cycle thru a pattern. I know how to do it with j1sys hardware and lightshowpro, but if I were to use a cheap standalone controller. What would I use. Can you get a cheap board which can be written too once (no sd card) and just repeat a sequence every time it has power turned on. What software would you use.
