I have a desk with a shelf above it, so I made a light strip I could put on the bottom of the shelf to light my desk area. I had some LEDs sitting around, but no simple way to make a circuit board for them, so I make a wooden housing to hold the LEDs and make a simple lighting strip. I made it at techshop in menlo park (http://www.techshop.ws
), using some tools in the woodshop and basic tools like the soldering iron.
Pine board (section of a 1x12, about 19 inches long)
25 white 5mm LEDs
soldering iron (and solder)
clamps and glue
