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.
We’ve published a new sample project that shows you how to use the Wixel and its Joystick App to convert a non-USB joystick into a USB device. This guide walks you through the whole process: all you have to do is make the right wiring connections and configure the app on the Wixel; no programming is required.
Check out the project page to see how we converted a Tandy Deluxe Joystick and learn how to adapt your own input device with a Wixel!

In this video, Amjad Al-Ahdal demonstrates his wirelessly-controlled robot with multiple modes that he programmed in C. The robot contains a PIC18F2455 microcontroller, an nRF24L01+ transceiver, a SN754410 motor driver IC, a Pololu wheel and encoder set, and two 100:1 Micro Metal Gearmotors. Its controller has a homemade keypad, another transceiver, a 9DOF sensor, and a serial 16×2 LCD screen.

The Robot Quartet is an art installation by Andres Wanner that features four marker-equipped 3pi robots working together to create drawings. The robots receive identical commands and draw repetitive patterns on the same surface.
You can see more pictures of the completed artworks on Andres’s website.

We have expanded our selection of NEMA 23-size stepper motors:
Here’s a sneak peek at some encoder wheels we are developing for our micro metal gearmotors:
The SparkFun Inventor’s Kit has everything you need to construct a variety of circuits that will teach you how to use an Arduino-compatible RedBoard to read sensors, display information on an LCD, drive motors, and more. No previous programming or electronics experience is necessary, which makes this a great way for beginners to get started with embedded systems. The V3 version includes a RedBoard and detailed instructions for building 15 educational circuits with the kit components.
This replaces the older SparkFun Inventor’s Kit for Arduino with Retail Case.
For more information about the SparkFun Inventor’s Kit, see the product page.
In this video, Brian Patton demonstrates how to program an animatronic robot using a Maestro Servo Controller. He covers basic configuration using the Maestro Control Center and shows how to sync voice with servo motion using software from his company Robodyssey.
