Picture a box... 2' x 2' x 8" :)
I used 1" stock to make the lid gasket. The trick is to do the lid before
you solder the sides to the bottom. Make some triangle gussets for the
corners to hold the box square.
I put the test subjects on a little microwave tray, and I have a loop
antenna, and some thru-bulknead signals using bulkhead wall BNC connectors.
I've been meaning to shoot one, but I don't have one yet.

Got a need to read Bar codes? http://www.barcodechip.com
Bi-directional read of UPC-A, UPC-E, EAN-8, EAN-13, JAN, and Bookland, with
two or five digit supplemental codes, in an 8 pin chip, with NO external parts.
