Farm Item Locator

The concept is to have 3 or more anchor points (aka: base stations, location servers, ...) that will triangulate the position of one or more "tags" that can be mounted to nearly anything larger than about 3 square inches. The tags should be cheap to construct ($25 or $30 apiece), and you should be able to have 100 or more tags in an area circumscribed by the 3 anchor points.

The initial concept occurred at FarmHack Intervale/Essex in 2012.
