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?

Cool project
Neil Sandstrom from the BEAM mailing list recently posted a notice about his "ShokHead" circuit built from our tutorial. What makes this project a bit different is that he mounted it on a VPM motor, so it's all self-contained. Here's what he says about it: Just finished!!! Check it out it is really small!! http://groups.yahoo.com/group/beam/files/Psyclesam/ […]
Supernova of Electronics
Here at Solarbotics, we like to celebrate things. And today we're remembering a supernova that took place in the Ophiuchus constellation and was observed by German astronomer Johannes Kepler back in 1604. That poor star, it was taken before its time. So to commemorate the memory of that star, (aptly named SN 1604, but we […]
Friday New Product - MicroSD Adapter, Po...
Welcome to the first Friday of 2013. This is better than the first Tuesday, because as you may have guessed, after the first Friday comes the first Saturday!
