"Most Adorable Robot Experiment Ever"

We are happy to announce the arrival of the Battery Edition Marble Machine. Starting today it is available at our website for backorder, and will be fully available for purchase starting tomorrow May 16. You are probably familiar with its older cousin, the Solar Marble Machine that has a clever circuit that delivers short bursts […]

We've been playing with the Pick and Place machine, and thought about new projects. This one, besides just being plain handy, offered us a simple project to start adding surface-mount parts to! The Ardweeny is proving to be a popular way to make a breadboard-friendly Arduino-clone, but after the prototyping is done, you still have […]

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.
