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.
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.
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.

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.

Pololu Forum user VolAnd, writing from St. Petersburg, Russia, posted about an app that turns a Wixel into a USB SD card reader. The Wixel identifies itself as a mass storage device, and basic read/write operations are working. His goal is to create files with the Wixel that he can then read from a PC. You can read more or get the app from his forum post.
This Wixel app and many others are available in our listing of community-contributed apps on the forum.

Brian hosts a YouTube channel where he uploads various control system videos that are intended to supplement first year classroom instruction. You might also be interested in some of his other videos: This video demonstrates closed loop control of a robotic car, and the videos in this playlist explain how to use a gyro with MATLAB/Simulink and Arduino.

Lunokhod, which means “Moon Walker” in Russian, was built for a space museum in Prague and is a miniature version of the first remote-controlled moon rover. It is uses 8 of our 298:1 Micro Metal Gearmotors and an Arduino Nano and can be remotely controlled by museum visitors.
