First of all lets get this out of the way... It's so bad
This is going to be showing how to hack the Nintendo Powerglove. By hack I mean tap into the flex sensors and use the buttons and d pad and add anything you want. In my case I added an accelerometer.
I got mine from Ebay for around $40. These gloves have 4 flex sensors similar to these: http://www.sparkfun.com/products/8606
Now these are $12 a piece, it's way cheaper to buy a Powerglove for 4 sensors and get a bunch of other awesome things then buy 4 of these.
Step 1: Materials
microcontroller (i used Arduino)
4 - 10k resistors
Nuts and bolts
Accelerometer or whatever sensor
Xbee with shield
I also have an Ardumoto shield with a vibrating motor for a feedback system
