The new S2 Scribblers from Parallax are in, and they feature a couple of cool new features. First: They're Open-Source! Yup, they've opened up all the design files to make hacking oh-so-much easier! Secondly, it's using the Parallax Propeller chip now, for mucho-improved computational power. They're already out of stock at Parallax, so get them […]
Circuit: Stepper Motor
Dave Hrynkiw
July 12, 2007
This is a neat little one-chip circuit we originally tuned for use with our "SM1" Stepper motors. We've presently sold out of the motor, but this circuit has proved to be a good unidirectional (1-way) driver for small stepper motors. Parts required are:
- 74AC240 Octal buffer chip
- 4 x CP0.1µF capacitors
- 100k resistor
- 2 x 47k resistors

GM10 Modifications
Grant has taken some time to document how to turn a standard 81:1 GM10 pager gear motor and turn it into a 9:1 version. Why would you want to do that? You tell me - I'd love to know what project you build with a speed demon like that! Read More...
GM19 Gearmotors in action!
We've had a great email come in from "Team Wazio", who are using our GM19 gear motors in their ant/fairyweight battlebots. Neat construction details - worth a look-see! (Yes, we know they're using the RW2 wheels and we're sold out, but we're taking care of that...)
