==Show & Tell== Rachel: Has lamont shift register to drive motor. Has functioning circuit using ultra-sonic ranger ("sensor module"). The Maxbotics works better than the Parallax Ping))), and it's half the size and easier to work with. They can also be daisy chained. Range is about 3 feet reliably, Ping))) was about 2 feet. They also sell different focussed version - more focus gives more distance, but less angle. Difference may be in code only. So sensing is a large problem - she needs 10 feet! Eric & Skory: New armature, with pockets & velcro & ribbon cable. New small circuit using RBBB and Shift Register. Analog compass which turns on motors? Ten pins sticking out in a circle. [http://www.robsonco.com/Dinsmore/sensorinformation-a.pdf Dinsmore 1490 Compass Chip Stat Page] [http://www.dinsmoresensors.com/index.html Dinsmore Sensors home page] Super promising for an entirely analog compass vibro-anklet, which would be much simpler and cheaper than current Ardiuno one, but of course less flexible.
