Hey! Are you in Calgary? Are you near Calgary? Is your name Calgary? If you answered yes to any of the first two questions (but not the third one - that's just plain weird), then you might be interested in hearing about the Mini Maker Faire that's happening here in the city tomorrow. From 10am […]
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?

Project: LED Earrings
The idea of adorning oneself with glowing bits has been around forever, but instead of smearing ourselves with phosphorescent jellyfish or placing fireflies in ears like some uncivilized cavemen we went for simple LED earrings. We made a build that involves a simple slow-scroll RGB LED and a few reflective bits to bounce that pretty […]
