I have a schematic somewhere, so I'll add that to a page and write up some other
info to the website when I get a chance (which will probably not be for a few
days).

That's a very good point. (I've always designed for sunlight, where heat is
important but not as critical as with Halogen. Perhaps I should start designing
for halogen instead - I have somelight-coloured cells ofdecent efficiency, as
well as a few of the super black ones and many shades inbetween. I should do
some halogen-heat performance tests)

Heh, I applied for a MDP position in the developing homebrew hardware/sensors
category, so (like everyone else) I'm hoping to win a spot in that lottery and
be able to start reverse engineering them myself :-)
I wouldn't be surprised if the new motors aren't quite as efficient though, the
existing Lego motors are amazingly efficient and that's got to be expensive. The
amount of stuff being crammed in the NXT box makes me wonder if motor efficiency
is one of the areas where the financial belt just has to be tightened. OTOH,
with no wall-adaptor power jack in the NXT, it's battery-only, and it's pretty
important to having fun that the batteries not go flat in just ten minutes.
Motors efficiency is probably the main way to prevent that, so who knows. The
motors look large enough to use the same high-efficiency guts as the regular
motors, so yeah, I'm really curious too :-)
