My Homemade Basic Stamp 2.

Got the kit for only $25 USD, over at http://www.phanderson.com
Half the cost of the real thing, but it takes a while to assemble. But putting it together is half the fun.
The Kit only comes with the 3 chips, 6 caps, 4 resistors, crystal and a diode + a bit of wire. The rest is up to you!

Here I have mounted the kit on a bit of veroboard I had lying around.
Click the image, to supersize it.

A bit easier on the wallet than this monster at $50USD :-)

Gotta amit though, a 24 pin package is nice and tiny.
Impossible to change the voltage regulator if it blows though!!
