Places to buy tools and supplies

Electronic Interface and Control

http://www.jameco.com/

http://www.digikey.com/

http://www.mouser.com/

http://www.nteinc.com/ NTE (sells the NTE521 high voltage tripler)

http://www.servocity.com/ Wide range of RC servos plus gears, drive shafts, and chains.

http://pololu.com/ Controllers and parts for RC servos, motors, sensors. Good prices. They don't screw you on little stuff. As a result I end up going to Pololu for buying bulk stock of power plugs, jumpers, headers, RC cables and connectors.

http://www.phidgets.com/ USB interfaces to sensors and controllers. Good stuff, but more expensive than Pololu.

http://www.atlas-scientific.com/ environment-proof sensors, sensor boards, data collection. They have pH, ORP, flow meters, power isolation. All boards provide I2C or UART serial with ASCII data format. Everything is plug-and-play, dead simple for microcontroller interfacing, potted in epoxy to be dirt and waterproof, and reasonably priced.

http://www.imagesco.com/ Geiger Counters, servo control, kits, hobby projects.

http://schmalzhaus.com/EasyDriver/ Stepper motor drivers.

http://www.sweetmemory.com/ Johnny Shami is a nice guy.
