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, Russell Kohn On Mon, 10 Feb 2003, Jeremy wrote: :Hello, : :I am new to the group and to wearable computers (well to the idea :of making my own) I have been interested in the idea ever since I :saw something on TV (PBS maybe) a long time ago about Steve Mann :and MIT. : :Anyway I hope to build my own in the next year or as my finances :allow me to buy the parts.
