Costs have fallen dramatically with the development board featured below selling for approximately $30. At that price it could be the heart of automatic antenna tuners, rotor controllers or a keyer as shown below.

Dimitris Sapountzakis quickly home-brewed a set of touch paddles from spade connectors and perf board.

Once connected to the Arduino micro-controller he was able to use those inputs to control they keyer code he wrote. Because the logic is in software rather than hardware he could add automatic ID, contest modes or practically any any other function as simply as changing a few lines of software.
With micro-controller prices being as low as they are now we may start to see a renascence in home-brewing and kit building. Much as ham radio kits educated an earlier generation, economical micro-controllers may allow this generations an avenue to experiment, design and create tomorrow technology.
