Effortlessly uploaded by Eye-Fi. This was a test of the Eye-Fi after I put the card in my Nikon S3000.
The toner gradually coming off the copper. The dots are holes in the copper that will guide the drill in the next stage of making the board.
This is the first laser printer - called the "Dover" - which was built at Xerox PARC. I vaguely recall that the resolution was something like 384x384. It was astounding in those days and could make the worst research paper look like something profound.
Close-up of the "after" restoration on the grinder. The metal nameplate was also recreated by thermotransfer of laserprinter ink from photopaper to aluminum. I scanned the original label into PhotoShop and touched-up all the missing text and graphics to faithfully re-create the artwork.

Before soldering on the proper parts, I wanted to test-fit some typical parts that might be used on a board like this. Some of them are required to get the microcontroller running, others are entirely optional according to the application.

The toner pattern on the board seems to retain detail very well. The edge areas had to be patched up, because I had scored the board along one side to make it snap off a larger piece. That score-line raised a tiny lip of copper, which prevented the iron pressing down on the board. Also, the shorter edges are patched because the printed pattern was narrower than the pience of blank PCB material.
Because this is a prototyping board, there are lots of holes to be drilled. A single-function board would require far fewer holes.
For the Stick Figures in Peril group, natch.
Inside this black plastic bag was a toner unit for a Dell laser printer. Today's society being what it is, you are recommended to treat this toner cartridge with the same degree of circumspection as you would a ticking box full of nitroglycerine, broken glass, anthrax, itching powder, and someone else's soiled underwear.
On a technical level, the surface of the bag was a bit of a pain in the buttocks to photograph, since the light from the fluorescent tubes in the ceiling above wasn't exactly conducive to a decent shot. Took me two passes with the gradient map in Photoshop to bring the details and contrast out.
I should explain, by the way: the intitial caption was "Spaceman Spiff" (from Bill Watterson's sublime Calvin & Hobbes) because I thought the outline around the head was like an astronaut's helmet. However, it occurred to me that maybe I was the only one seeing that, hence the slight change.
