Let's play "Spot the differences"! We received some new inventory, and one of these things ...was not like the other (Sesame alumni, we are!). FYI, here are some differences between the K1 series of hot-ends. I don't believe them to be "OMG!" differences, but just worth noting. We've had good results with both styles, but […]
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?

More new stuff... SC3782!
Cool! We've found some SC3782 (37x82 mm) solar cells! Since Panasonic ain't making these anymore, and there aren't many of these left, you'll only find them here at Solarbotics until they're all sold out. Get'em while they're hot!
