Fixed a reset problem in the sumo code, turns out the a If...Then statement does not store its location on the stack. Ergo the return instruction at the bottom of the turn function was pulling a random location. Anyway a change from a return to a goto and everything is shipshape, savvy? Then download the […]
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?

Everybody have a good 2010? Good...
Let's start 2011 by promoting a worthwhile event sponsored by one of our suppliers, SparkFun. Tomorrow is their 2nd "Free Day". Last year's event pretty much crashed their servers (we sent flowers of condolence). This year, they're going about it a bit wiser, offering several ways to taking advantage of their $150,000 give-away. We're big […]
