May long weekend is upon us up here in Canada, with Victoria Day being Monday. Ahhh, time to melt the igloo, unshovel the lawn mower and scrape away the ice so we can plant snow-peas! (Joke - it's actually quite nice here in Calgary right now...) Anyway, any orders received after 2pm today will not […]
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 Yellow Treads
Want a bumble-bee look to your robot tank? Intersperse our new GMT-Yellow treads into the link chain! You should even be able to use a yellow link as a opto-reflector in a wheel (err...tread?) encoder circuit. ALSO, we're the only place in North America you can get these new yellow tread links!
Project (the day other than) Monday: Ice...
Inspired by the Ice Bulb published on Instructables, we decided to create our own version. Ice bulb suggests that we use a balloon to shape the ice and before it freezes, add an LED so that it can glow. Since we decided to use a whole bunch of LEDs (on a string), we opted to […]
