I have been in the process of developing a AVR/Arduino 'Stamp', pin for pin compatible with the Basic Stamp BS2, such that it can be used on a Boe-Bot. I have more thoroughly outlined my motivations here:
My results on that site are not quite up to date - I have worked out a couple of kinks, corrected a couple of errors, and am finishing up a second board layout.
I am interested in assembly services, since my school will be ordering at least 35 of these. I have e-mailed the arduino development team, but they have yet to get back to me. Any recommendations? Is anyone else interested in this project?
