Hello Dave,
Glad to hear about your exploits in the arduino world. Myself and a colleague wrote a curr. Guide for this tool and managed to get it out to a few Jr. High schools but couldn’t get the support ( read money) to get it out to all schools. I am now retired from the dept. but my French colleague, Justine Arsenault has been doing her best to keep this project alive in schools. She could send you a copy of the document to wet your whistle. Students who have been exposed to this just love it.
