TV background lighting

Postby Loewe88 » Wed Oct 24, 2012 4:29 pm

Hi,

I received my plasmatrim today. I "installed" one behind my TV screen for background lighting controlled via a raspberry pi. Works perfect :)

The raspberry pi can also power and control two plasmatrims with only one standard cellphone charger as power supply.

Very cool. Ya the RasPi would be a great platform to use for them.

Have you tried going up to full brightness w/ all the LEDs on white and compared that to the unit looks when powered by a different device? I ask because the RasPi has a hardware current limit on its USB ports and I am pretty sure it is much lower than what a PlasmaTrim wants for full power.

Also, software wise, how are you controlling them?
If PlasmaTrims were super cheap I would be playing snake on a 32 PlasmaTrim square by now.... over wifi.... from my phone and/or N64 controller.

If you compare it directly you see a little difference. The direct powered Unit is a brighter than the RasPi powered one.

To control die PT I connect currently via ssh and use your CLI, which works very well.

Well, its great to know that it won't cause the PlasmaTrim to do funny things due to a lack of power. In my opinion being a little less bright is not really a problem - these things are blindingly bright, when I have been working with them I keep them at 1%.

I'm also glad to hear that someone is finding my work useful. Make sure to check back for updates every now and then, it is still very young and a work in progress. I'm sure you're not the only person who will want to do things over the network, I might look into doing some kinda network based daemon to allow remote control over some open protocol....
