I just got my hands on an electric wheelchair for $20... any ideas? Has anyone interfaced a wheelchair to a handyboard before? I'm not sure if I want people riding on it, but I'm thinking I can mount a vacuum cleaner under it or something ;-) -phil (25 years ago, 16-Sep-99, to lugnet.robotics.handyboard)
