I've got a new camcorder, the old Cannon bit the dust.
Unfortunately the 6V gel-cell battery that I used to
power it won't power my new camcorder because that one
needs 8.4V. So, what I need (I think) is a DC-DC converter
that takes down to 5.5V and bumps it up to a nice clean
8.4VDC @ 1A (the rating on the A/C adapter that came with
the camera). Is this something that's possible?

Next up, I want to build a nice NiMH charging circuit
that uses temperature to control the charging cycle. I know
it's a bit more complicated than that, but does anyone have
some good sources I can start learning at? I've been using
the cheap timer chargers but I find that typically the AA
cells are too damaged to be reliable after only 10-20 chargning
cycles.


Start with companies like www.maxim-ic.com, www.national.com, and
www.faichildsemi.com, find parts that meet your needs and request a few
samples. www.ti.com has some good parts for these purposes too.
