We have just released a joystick app for the Wixel that allows you to turn a Wixel connected to a computer into a USB joystick, with the Wixel’s analog and digital inputs representing joystick axes and buttons. The app and its documentation can be found in the Wixel User’s Guide, and its source code has been added to the Wixel SDK.

We’ll soon be publishing a sample project that shows you how to use a Wixel running this app to convert a retro joystick into a USB device, so stay tuned!

Update (12 September 2013): The Wixel USB Joystick sample project is now available.

Our universal mounting hubs are now available in versions with mounting holes sized for M3 screws (not included). These aluminum hubs allow you to mount custom wheels and mechanisms to 3 mm, 4 mm, 5 mm, and 6 mm shafts. Each set of two hubs includes the required set screws and an Allen wrench for securing the hubs to motor shafts.

We have released a new machined aluminum bracket that lets you securely mount our 37D mm metal gearmotors to your project. The bracket has six holes on its face that line up with the 37D gearbox’s mounting holes, and it has three tapped holes on the bottom. Nine M3 screws are included for securing the bracket to the motor and mounting surface.

Our new QTR-3A and QTR-3RC reflectance sensor arrays pack three IR emitter and receiver (phototransistor) pairs onto a board measuring just 1.25″ × 0.3″ (32 mm × 8 mm). With the sensors mounted on a 0.375″ pitch, these sensor arrays are great for sensing 3/4″ black electrical tape when used as minimal detectors on line-following robots!

Two versions of these sensor modules are available: the QTR-3A provides three analog voltage outputs, while the QTR-3RC provides three digital pulse signals that can be read with digital I/O lines.

The SparkFun Starter Kit for RedBoard is an easy way to get started building entertaining and educational circuits with SparkFun’s RedBoard, an Arduino clone that is compatible with the Uno R3. The kit includes a RedBoard along with various types of sensors and indicators. A downloadable guide features example projects to introduce you to the world of embedded electronics.
