Ytai from Tel Aviv wrote in with a cool new board he developed:

I’m very excited to announce the launch of a new product I’ve been working on for the past months! IOIO (pronounced: yo-yo) is a product which lets you connect electronic circuits to an Android device and control them from an Android application. It is comprised of a small (2.7×1.2″ = 7x3cm) PCB that connects to an Android device with a USB cable and a software library (Java .jar file) that you use in your Android app which handles all communications with the board.

No firmware programming is required – only Android application authoring with a very simple API for controlling the pins on the board. No modification of the Android device is required – you avoid the complication of modification and the voiding of warranty.

The board will be available from Sparkfun.

    That, I would like to see…

    Nicely done! I think it’s a bit expensive at $49.95, but Sparkfun never been cheap OTOH….

    Maybe you can have Seeedstudio make a batch of them? I’m sure then will sell rather well.

    Soooo….I have this Droid X…I have this habit of tinkering with Arduino-based schtuff…now I have IOIO. Seems entirely awesome, but I haven’t actually learned to develop for Android; I’m a hunt-and-peck C++ girl at best. What kind of learning curve will I be facing??

    • Ytai Ben-Tsvi

      The IOIO side is fairly easy from someone with an Arduino background.

        Thanks Ytai! Something interesting to keep me out of trouble this weekend….
