Step 1: WHAT YOU NEED
1) A Binary Watch (http://www.thinkgeek.com/gadgets/watches/6a17/) After much use, mine needed some upgrading.
2) A Small Flash Drive (Consider the Pico Drive: http://www.thinkgeek.com/computing/thumb-drives-storage/a6d9/)
3) A-type USB connection and receptacle (A USB extension cable works good for this)
4) Leather-like material to conceal your inner workings.
5) Safety Glasses, Soldering iron, Solder, Scissors, Sewing Supplies, Crazy Glue, and a Dremel tool (optional).
