Atari 2600 Joystick to an iPad

Allen Huffman used a Teensy 2.0 as an interface between arcade joysticks and an iPad.

The project came about when he was having difficulty getting an expensive input board to work in a haunted house attraction.  When he discovered that the iCade keyboard commands worked over a USB connection, he figured he could use an Arduio board and hood the USB side to an iPad and create his own interface.  With a bit of research he got his project up and running.

Be sure to check out his forum post for details on how the project came about.  The code for the project is available on GitHub.

Arcade Joystick x4 Plus Simon Game

David Guerrero made his own arcade table for playing Simon.


This video shows a demo of the game play.

While he used genuine arcade joysticks and a vintage CRT display, it was still lacking in authenticity.  The risk of a $0.25 loss was missing.  Since emulators basically allow unlimited lives, taking away the gamble of a valuable coin, David disabled that feature and created a little challenge that must be won to add more coins/lives.

The code and many other details about the project (like how to obtain the valuable game play credits) are available on GitHub.



Mario the Maker Magician’s Robot Bunny

Mario the Maker Magician made a Robot Bunny that can be magically pulled out of a hat.


The bunny is made from flexible PLA.  LED Matrixes were used for the eyes and a couple of servos were used for the paws.

Mario said the what he learned most from the project was how to multi-task with the Arduino platform – taking the delay function out of his code, but still being able to control 7 LEDs and make 2 servos work at the same time.  The size of the Teensy was perfect for this magical bunny.

Wake Up Wake Up Video Meme Alarm Clock

Fuzzy-Wobble published an Instructable for a Meme Video Alarm Clock.   This custom clock plays a video of your choice for the alarm, but of course the “Wake Up Wake Up” clip featured in the video makes for a pretty awesome alarm.

The Instructables page provides all the code and instructions for making your own, including instructions on formatting your own custom video and the files for laser cutting the enclosure.

TGA Pro : Guitar Audio Shield

Forum user Blackaddr developed a guitar audio shield .

The TGA Pro is  stereo-sound capable and designed specifically for use with guitars providing an onboard preamp specifically designed for the wide range of voltages and impedances encountered when dealing with guitars, pedals and guitar amps. It also provides onboard MIDI connectors for use with the Arduino MIDI library, and optional external SRAM for additional data storage. This shield makes it very easy for musicians to add effects while playing guitar.

You can read about the board’s development over on this forum thread.

In this video demo the only gear used is a guitar, the TGA, a MIDI expression pedal, and a tube amp.  The expression pedal is used to open the input to the SOS channel and feed in the same chord in two different octaves to get a nice blended background ambience.

Be sure to check out blackaddr’s Tindie page for all the details on this shield.
