The parts I got from several varied sources - Parallax, BasicMicro,
Budget Robotics, Fry's, Radio Shack, Gateway Electronics, Home Depot
supplied some plumbing parts, and stuff from my garage that I had for years. One of the toughest
problems I encountered was debugging the speech board which was wired-wrapped and also soldered. It
took bout six weeks to complete the hardware and software. I am still enhancing the software. Cost
was about $300.
