Places to buy tools and supplies

Electronic Interface and Control NTE (sells the NTE521 high voltage tripler) Wide range of RC servos plus gears, drive shafts, and chains. 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. USB interfaces to sensors and controllers. Good stuff, but more expensive than Pololu. 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. Geiger Counters, servo control, kits, hobby projects. Stepper motor drivers. Adaptors for PCI, USB, memory cards, mini-PCI. Lots of embedded adaptor cables

Sweet Memory will ship free in San Francisco via messenger, so if you need a memory or a drive and you can't leave your office then you can still get it the same day from Sweet Memory. Prices are decent for a storefront in SF.
