New GMPW Wheels!
Dave Hrynkiw
June 21, 2007
No more rubber band tires for us! We've invested in getting our very own wheels made for us, with molded-on thermoplastic rubber wheels!
These wheels are slightly larger in diameter than the old style, measuring 69.2mm (2.72") diameter and 7.65mm (0.30") wide. Ah, but how good are they? They're definitely better than the old style! We know from head-to-head tests that these have better traction than the rubber-band tires (definitive numbers are coming...). We've also spun them up on our lathe to see how true the mold process is, and they're quite true - no visible wobbling!
A new enhancement is a built-in opto-reflector 32-step pattern! Built to be bolt-on compatible with the Wheel-Watcher series of wheel-encoders, all you have to do is paint the groove white (for dark plastic wheels), and scrape away the raised surfaces to generate a sharp, accurate 32-stripe pattern!
Did we mention that there was no increase in price for all these enhancements too?

New Stuff!
We've been busy little elves at Solarbotics. New to our product listing is a fair number of parts and ICs that have been requested of us. Like what? Wellll...: You always need new chips. Especially when somebody on the BEAM list has made something cool: LM324 Op-amp (happy now, Bruce?) LM393 Dual comparator LM386 Audio […]
Circuit: Herbie by Randy Sargent
Although not a true BEAM robot, this simple schematic by Randy Sargent is small, simple, slick, and effective. My own version uses a pair of pager motors and three cells from a 9V rechargeable battery. Hard to get any simpler than this device!
Solarbotics has been operating for more than 25 years, bringing electronics know-how and supplies to both the electronics professional and hobbyist. We'll be happy to help you too!
