Do you have access to a computer with an RS-232 serial port?
If not, you need a USB serial adapter.
Either way, you need the special connector for a Kindle 3. I plan to make one using simple easily obtainable ingredients, such as thin plastic (old credit card or CD cover), aluminum foil (or copper foil). I will do one method for soldering, and another that uses conductive paint from an auto parts store (for repairing a rear window defogger/defroster). I will document this (with photos and video). The non-soldering method is needed because many people said they did not want to solder. Conductive paint is somewhat expensive, but it will last a long time when used as a solder replacement.
Where are you located (I will have extra prototypes)?
