Hi, Does anyone know of a good place to get material for building a frame for a robot - preferably aluminum?

The Wavecom Jr. from RFLink (~170$ for a xmit/receive pair) does color video and stereo audio in the 2.5Ghz band. Much better than the 900Mhz stuff. Can get it from Sharper Image (1-800 something...call 1800 555 1212 and ask). Can run off 12V (...) (28 years ago, 4-Dec-96, to lugnet.robotics.handyboard)

The SPI (synchronous peripheral interface) does not do normal RS-232 (aka "asynchronous serial") in hardware. you must write an assembly language driver to do the timing. at some point in january i plan to release a 1200 baud output driver. if (...)

(...) I put one on my project. Expect video dropouts from Rabbit type (i.e. 900 MHz) devices, when the robot goes behind trees, dense walls, and other areas.
