Welcome to the Pololu Blog, where we provide updates about what we and our customers are doing and thinking about. This blog used to be Pololu president Jan Malášek’s Engage Your Brain blog; you can view just those posts here.
This instructable shows how to power an Arduino through the Pololu Pushbutton Power Switch and use the self-shutoff feature.
This replica of the famous Star Wars droid R2D2, built by Glenn Pipe, uses a Jrk USB motor controller for position control. The video below shows how Glenn uses the Jrk Configuration Utility to control and analyze his system, and his blog post has more information.
In this video, Meindert Norg from Norg Consulting demonstrates his active magnetic bearing, Tripod Floater. The closed-loop system uses three Pololu 18v15 high-power motor drivers as PWM amplifiers to power the magnetic coils that keep the module floating beneath the metal plate.

This DIY article for Popular Science shows how to use our Orangutan LV-168 robot controller to make an autonomous, obstacle-avoiding 1:32-scale Hummer. The Arduino sketch used to control the car makes use of our Arduino Orangutan libraries and is available for download on the second page of the article.
