== Wireless, programmable Datahand ==

After having used an old dh200 for a few months, I was used to having more room to spread my hands apart with the datahands.  I often type with one hand on the desk and one hand on my chest, and with the short cord between hands on the ProII, it's somewhat limiting.  In addition, the limit of 20 macros was not enough.  So the logical solution was to follow another project I had seen on geekhack.org  ( http://geekhack.org/index.php?topic=12212.0 )  and replace the chip in the datahand with a teensy, then make it wireless.


To do this, I got the following together:
* 2 teensy++2.0 chips from http://www.pjrc.com/store/teensypp_pins.html
* 2 teensy xbee adapter boards from http://www.pjrc.com/store/xbee_adaptor.html
* 3 XBee 1mW Chip Antenna - Series 1 (802.15.4) https://www.sparkfun.com/products/8664
* 1 Arduino Mega 2560 board I had sitting around http://arduino.cc/en/Main/ArduinoBoardMega/
* 1 Arduino xbee shield https://www.sparkfun.com/products/9976
* 2 Evo External USB Battery Packs http://www.amazon.com/gp/product/B0061S10LS/
* A couple 40 pin dip sockets to remap pins on the teensy (and a couple are needed because they are easy to break) - found at https://www.sparkfun.com/products/7944



The final product looks like this:
