Here's a funky motor for you - the GM19! Slightly larger than the other metal gearhead series (GM11-14), and with a larger motor, this 35:1 beasty looks like a good contender for building mini-sumos or other small, speed-hungry robots! But be warned: It is a bit strange. The gearhead is mounted askew to the motor, […]
Sumovore Brainboard - the PICAXE!
Dave Hrynkiw
November 5, 2008
It's been a bit long in the coming, but it's finally here: The Sumovore PICAXE Brainboard for the Solarbotics Sumovore!
One of the biggest tripping points we see from going from the pure digital/analog realm of BEAM to microcontrollers is learning the ins-and-outs of microcontrollers. The PICAXE nicely fills this void by offering a programming interface that is ...just a flowchart! Draw your logic diagram, hit program, and you're off and running!
We initially designed the PICAXE Brainboard to support both the 18X and 28X1 chips, but we've decided to simply package the kit with the PICAXE-28X1, which is a $10.50 chip itself. The 28X1 has enough I/O to support all the sensors (the 18X only supports 3 edge sensors), plus it has more memory and support for I2C (handy with several I2C-It sensors).
Here are the specifics:
- Support for the PICAXE-18X, 28X/28X1 microcontrollers
- Easy PICAXE 1/8” jack programmer interface
- 5 indicator LEDs
- Official PICAXE PWM Interface IC to drive motors
- Microprocessor reset switch
- Standard 0.1” expansion interface holes for breadboard add-ons
- Spot for optional resonator for more accurate timing
It's another convenient way to expand the capabilities of your Sumovore!

New Hakko Iron & SMD LoL Shields
I wasn't very interested when the new Hakko FX-888 soldering iron showed up, but as I opened it and explored more, I got to thinking "Dang - this is a nice iron...". It's small, heavy, made-o'-metal, and of Hakko quality. And it's better than the old 936 it replaces, in practically every regard. And it […]
