YaNiS EOS is a free app, currently in beta, written by “Manis,” a physics student at the University of Luxembourg. The hardware stack consists of an Arduino, a USB host shield, and an SPP-compatible Bluetooth module.
The miniaturized version he shows off here uses a SparkFun ProMini 3.3v, a matching USB shield from Circuits@Home, and a SparkFun BlueSMiRF, respectively, plus a small LiPo battery pack.
Attached to the mini USB port on his Canon 1000D via a standard-to-mini adapter, it’s a bit of an ungainly package, but it’s completely self-contained, and provides full wireless aperture, shutter speed, ISO, white balance, focus, and other controls.
The app is a free download from Android Market. The Arduino sketch is posted at Google Code. Build notes are available on Manis’s personal blog. [Thanks, Matt Mets!]
