[QUOTE="Rick164, post: 1111721, member: 17766"] Was using SEDU as well before, for solo solutions (MediaPortal) this is still the easiest to setup and costs a bit less as well however you can't use the newer leds. Hyperion is in active development as well which is nice as they learned a lot from Boblight and are bringing a real efficient/fast amiblight system over network. CPU wise it's no problem, with WS2801 leds connected (90 total) to the rPI the rPI used about 30% and Windows wasn't affected as all is handled by Hyperion externally :) For the WS2812B leds the Arduino was added which is much more efficient at this so the rPI uses about 15% with that setup, don't see any problem with going above 300 leds with that setup as well. With AtmoWin the calculation is done locally but with Hyperion AtmoLight sends an image over network and it gets handled by it, this way on the low/mid HTPC setups it will work a bit better as well as the cpu has to do very little extra work. The extra leds don't add that much to be honest, you just get less "blobbing" as there are more leds for moving objects (easier to distinguish). However the color range is a bit better on the WS2812B ones as far as I know so that would be a another benefit. Think once you get above a certain amount of leds it doesn't really matter anymore, had 90 before (30/15 sides) and that was already pretty nice. For video capture it became a little complicated as you can't use 24p mode while the HDMI -> composite converter is powered on (technical restrictions), so what I did was add a remote controlled brick and toggle that via remote when needed. If it's on and you run Mediaportal the HDMI signals will still be restricted to 50/60hz as your AVR is still limited by the powered on HDMI -> Composite converter. Basically you only want to turn on the video capture if you are using anything else than Mediaportal, will add this part to the guide as well as that seemed to have gotten lost during copy/paste. /edit: added extra information under "[B]video capture setup[/B]" (* important * headline).
