[QUOTE="Lightning303, post: 1119310, member: 97876"] So i build this system for a friend of mine. I ran into some problems but with the help of [USER=17766]@Rick164[/USER] we got it to work :). However i wanted to give some infos on what i found out building this. First we triend OpenElec 5.0, as it is the newest version. However we were not able to start Hyperion even. Maybe i just fudge something up along the way, or its just not working out of the box, a linux pro can probably get it to work in no time.

We bought a arduino nano clone from ebay with a CH430 usb to serial chip. And oh wonder, it cant support baud rates higher than 115200. With 233 leds, thats of course not enough.
