How to Listen to Light

Step 3 (OPTIONAL STEP) Cutesy recycled circuit board circles!

Uh... lets see... This step involved: De-soldering parts from a junk circuit board. Cutting off a piece of depopulated board with a radial arm saw. Using a hole saw to cut out some little circles. Then attaching the circles to a bolt, and loading this bolt into the drill press, for purposes of slimming down the circles, decreasing their radii by placing a file against their edge, while the drill press is spinning them. Then sanding the paint off the little circles by rubbing them against a sheet of sandpaper held to a clipboard.

Then I carefully broke off a piece of solar panel shard. Then carefully soldered it to one of the little circle boards I made, and then I soldered some wires to the appropriate places on the panel.

Verily, this is the story of the genesis of the little circular solar-cell board seen in Step 2.
