He shows it on a teensy, which if you're decent with a soldering iron can be done for as little as $16 + shipping. power supply is usb so no extra cost there. not sure how well talking to a phone would do directly but worth checking into.
That's right on the money, but technically I'm using a nano. Any Arduino will work though. There are knockoff Arduinos out there too, but I like to give back to the Arduino organization by buying an official board.

$16 for the whole thing? The board, the sensor, the connectors, the power supply? I don't think it's even close to that.
