:Hi,
:
:sounds like you've got a good start. I'm using the PCM-5822 and its a good
:all-in-one board. You can get it directly from Advantech
:(www.advantech.com) and the 300Mhz version was $420 last time I checked
:(if you find that has changed, definitely say something).
:
:As for power supply, you'll need to do a little bit of work to make a
:board that will convert whatever your battery input is to 5V. Theres the
:PT6302A (I believe made by TI) which you can purchase from Digikey
:(http://rocky.digikey.com/scripts/ProductInfo.dll?Site=US&V=228&M=PT6302A)
:for like $25.
:That'll convert 9-30V to 5V at max. 3A
:
:So that should work for most battery configurations as well as wall warts.
:What batteries you want to use is a whole 'nother ball  of yarn (Sony
:camcorder batteries vs. Laptop batteries).
:
:And hopefully by the time you're looking at getting an HMD they'll be
:reasonably priced!
:
:Good Luck in all this,
