Yes, it's true. After years of working our fingers to the bone inserting jumper wires on breadboards to make unusually robust controllers for robots out of discrete & logic chip elements, Solarbotics has seen the light! We've put on our eye-patch, hoisted the jolly-roger, and swung along-side to board the HMS HVWTech.com ! That's right […]
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

Organizing the Advanced Section
Every once in a while we like to re-arrange the furniture. Sure, it's nice to have things look new and different, but most of the time we're just trying to make things just work better. This week we've done a little bit of restructuring of our Advanced category - we hope it'll make it easier […]
Solarbotics Antweight
Adam Conus sent us a nice little message about his antweight combat robot The Fly.: Western Allied Robotics is kicking off another year of antweight combat events and I need new motors. (Because I'm very, very hard on them!) Still, they're cheap and light. Check out- http://home.comcast.net/~conusa/adam.htm to see the robot complete with solarbotics sticker!
GM15 Dual-Deal; Microcontrollers!
Ok, ok - we've been getting requests (no; more like demands) that we offer a bit of a deal for getting the GM15's in pairs. Alright then. How does $30USD or $40Cdn a pair strike you? Ok, now let's see some nano-sumo robots! "Wot's this? A microcontroller at Solarbotics??" Yup. The Atmel ATMega8L is part […]
