The Stamp is a great!! product. What makes it particularly appealing is the
fact that it can be refreshed or reprogrammed via software (even modem if
necessary). There is also a company called Edwards which creates expansion
circuits for the stamp.
The memory limitation of the stamp provides a fun challenge for those who
like to write tight code.
Anyone have an interest in creating a circuit diagram repository over at
