RE: Finaly a cheap possible wearable solution?

did you remove the fan or do you just have a slightly
different model?

what type of batteries are you using? run times?

good to hear from someone using it.

I've got an Epia 800 right now.  I've never tested its power consumption,
but I do know that its heat output is relatively low.  As long as you don't
insulate it too much, it shouldn't overheat.  Mine has no CPU fan, just a
heat sink.  I just keep it well ventilated, and it stays within safe
operating parameters.  If you plan on packaging it in a bag or pouch of some
sort, you'll probably want to ensure that it has decent air flow over the
heat sink.  You would have to worry less about the Eden 500 board, but you
would be making a large sacrifice in computing power.  It's always a
tradeoff.
