ThinkGeek’s new Motherboard Ruler is perfect for science geeks, computer nerds and math dweebs who need to measure stuff. Each one is made from a sliver of recycled green circuit board, probably from your old laptop that died.
ThinkGeek likes to throw around fancy stats like the fact that the ruler measures 1.067 nano light-seconds long, but according to my computations, I come up with a length of 3,048,000,000 angstroms, with an accuracy of 16 15,875,000 angstrom sub-segments.
So get to measuring and grab one over at ThinkGeek for $7.49 (USD).
