SparkFun at Android Open: IOIO Untethered and Meet the Electric Sheep

One of the projects featured at the Mini Maker Faire was Ytai Ben-Tsvi’s IOIO, an Android hardware accessory kit that predated the Open Accessory Development Kit (ADK), and is a bit simpler to use: there’s no need to do any programming on the microcontroller, you can load firmware updates from the Android phone, and the Android programming side is pretty darn easy, too. On top of that, the IOIO supports a lot more phones than the ADK does: while the ADK requires Android 2.3.4 or greater, the IOIO will talk to a phone as old as the G1!

I set out to write a generic “props” round-up, but quickly discovered that our props tag is pretty deep, and covers a wide range of subjects including haunt props and/or prop furniture, elaborate costumes, and display props. I narrowed my focus, then, to props a person might carry around as part of a costume, and found, even then, there was more cool stuff than I could fit into one roundup.
