In this video, Derek Molloy shows you how to make custom cables using our pre-crimped wires and crimp connector housings and does a great job of showing how to use our crimp tool properly.

Paper ROM and balsa wood airplane

Posted by Jon on 26 August 2013

Customer Mike Kohn recently wrote to us about two of his projects that use Pololu parts:

This paper disk is marked with black and white patterns spread across four distinct rings and can store a total of 16 bytes of data. Mike decodes the data with one of our QTR-1RC reflectance sensors. Read more about “PAPER-ROM”…


This balsa wood airplane uses an ATtiny85 to interpret signals from a Syma S107 helicopter remote controller, and it uses our 5:1 micro metal gearmotor HP to spin its propeller. Read more about this airplane project…

Mike has documented many of his other software and electronics projects on his web site.

Dagu Rover 5 controlled by a Raspberry Pi

Posted by Zeeshan on 23 August 2013

Pololu forum user chrisptx posted this video of his Dagu Rover 5. He is using a Raspberry Pi as the main controller and sending signals to a TReX Jr Dual Motor Controller for drive control.

This rover is controlled by a Samsung Galaxy S3 smartphone, which uses its web browser to send commands to the Raspberry Pi in Javascript.

Controlling a Maestro in C using a Raspberry Pi

Shahmir Javaid tweeted about a tutorial he wrote that describes how he used a Raspberry Pi to control a Maestro servo controller in C. His tutorial documents the steps he took, including setting up the Raspberry Pi for UART, wiring, and programming. The setup is simple, and the code is provided.

Internet Controlled T-Slot XY Table

Posted by Grant on 22 August 2013

A customer sent us a link to this instructable that shows how to make an automated XY table that can be controlled through the internet. It is constructed from T-slotted aluminum extrusions and uses an Arduino and jrk 21v3 motor controllers to drive the axes using a pulley system.

You can interact with this XY table by going to TeleToyland, which has a browser based interface that allows you to draw an image and watch the XY table reproduce your image in a sandbox.

Tron Suit Costume

Posted by Kevin on 19 August 2013

Swap_File posted a write-up of this Tron-inspired costume on the Adafruit forums. A pair of Wixels — one in the disc and another in the jacket — helps to enable wireless control of the suit’s lights and displays.

The costume was featured in a Wearable Wednesday blog post on the Adafruit blog.

Brute Force Car Radio Code Solver

Posted by Jon on 19 August 2013

Forum user Christian, writing from Germany, posted this video of an automated system he built that pushes buttons on a car radio (Becker Mexico CD 876) as a brute-force method to determine its radio code. In his system, he uses our Mini Maestro 12-Channel USB Servo Controller and 10 servos to extend rods of wood to press the numbered buttons on the radio console. You can read more about his system in this forum post.

The setup had already run for 3 days straight, but Christian expects it to take another 30 days to finish entering all 10,000 codes. We look forward to hearing back from Christian once it finishes.
