OLPC Sunday Adventures: XO-1 + Tinkertoys = Cantenna!!!
I've been playing with the idea of a Cantenna for the XO for about a month now. I finally had some time this Sunday to assemble a test model.

This is a cantenna and frame assembly constructed from:
1.) One cylinder Tinkertoys can with Tinkertoys
2.) Tin Foil
3.) A broken XO antenna

The result? A high powered, low cost directional antenna for an XO.

The original idea (and Tinkertoys) came up from the School-in-a-Box Jam in Manhattan at the Manhattan Neighborhood Network (MNN.org):
