Our GraviTrack Marble Machine Kit is our newest addition to the Marble-Drop mechanism family. Elegant, swooping hands pass marbles to each other to the top of a sweeping multi-level track, available in either solar or battery configuration! Approximately twice as wide as our spiral Solar or Battery Marble machine kits, the GraviTrack is still desk-top compact but large enough for easy mechanical assembly. Pre-order yours […]
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?

Harold's "Tank"
Harold Ilano built this SW2.2 / VBug inspired 5 motor walker named "Tank", and just recently announced it on the BEAM mailing list. It's a very effective and quick device - nicely done, and well worth a look-see. It still impresses me what we can do without a microcontroller...
Project Monday: Pingbot
Tom from our Facebook page recently showed us his latest project, the Pingbot. In Tom's words, it's "a very small (38mm diameter), usb rechargeable, programmable, musical, remote control robot designed for maximum fun and danceability." We don't know about you, but danceability should be a priority on every robot's feature list. Check out some video […]
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 […]
