Pico Projector

Has anyone tried one of these pico projectors?
If so, how did it work out, is it tolerant?

I tried one that was a little bigger than most.  But it was
a disaster even with a large filter and metal box.
Apparently DLP is not the way to go because the LEDs
are switched fast at high current.  The LCD ones
are a better way, and some of them now use LED lamps.

Richard Conrad says there's a new one for around $1000
that someone should try-- it will need a custom power supply
for the LEDs, they probably run at 3.3 volts or so.  I've
read that with LED's you either have to regulate based on
current rather than voltage, or fine tune the voltage for
each LED if you want best brightness.

Let us know if you get anywhere with it.

small pico projectors say one by optoma are quite good and run off leds,  
sadly noy the best of briteness just yet although this is improving. I see
where  holographic projection has taken a quantum leap it is said to be a
viable  technology right now with refresh rates to the image of 20 secs
