Dear Doug:
Can you help me with this? Please don't send me all over the place with links. I do not enjoy surfing as you seem to.
Do you have any personal RF experience you are willing to share. Can you write a few sentences giving your recommendations? What about performance and price?
Could you "actually" build a prototype for me?

Whoa, that is really cool Jim! Yes, I want to do something
similar, but I want a complete PC on body to do real-time
analysis and recording. A while ago I had a baseball cap
with a tiny display that points in my eye, it was 320x240
resolution. It gives you an "augmented reality" experience,
you can see the "real world" with one eye and also your
computer output with the other eye. It tricks your brain
into seeing one image, therefore you can overlay digital
data over your environment. Companies like boeing are
using stuff like in aircraft maintenance, you can look
up schematics and voltages etc while working on engines.
Jim, you should photo that baseball cap EEG and put it
up on your web site as a snapshop of some of your EEG
hackery.

Jim, there are tons of low-cost transmitters out there
these days. It really depends on what speed and range
you need. You can get tiny RF transmitters/receivers
from laipac for under $10. I know people who are using
these to make wireless single-handed keyboards and mice.
They also have 900Mhz spread spectrum modules that can
transmit through walls. Check them out:

I have more links to wireless stuff here:

http://home.earthlink.net/~wearable/#Wireless
There is tons of hardware info on my wearables page:
http://home.earthlink.net/~wearable/
But I call it hardwear and softwear. I want mobility.
I want untethered continuous "always on" computing,
including bio monitoring.
