People were learning how to solder and I assume put together a circuit board? I didn't get to ask questions, but it looked like fun.

Punch holes on the centre crease of some thin card, then fold sides slightly away from the holes, and create a triangular ridge. This card can then be glued to a firm card with the ridge sticking up. Mock-up done with old envelope. For surface mounting (e.g. a bulletin board), only a strip of card next to the second crease is necessary, just enough to glue it to the base. This mockup is also used to demonstrate a cover, which is why it is much wider.
Strictly speaking, for surface mounting, it is not even necessary to use binding disks, as the surface gives rigidity, and one could just attach loops of wire or even narrow strips of plastic (e.g. strips cut from milk bottles), which could be stapled on or threaded through a couple of holes for each loop and attached at the back. The centre of the disc is only necessary to give the binding firmness in a book format. If one used individual rings on the spine, they would just flop and allow the paper to 'float' around.
Edgeware Road has a confusing layout so in a surprising example of a great hack the platforms have a normal TV with a simple video camera feed thats pointed at the departure boards above.

Note the connections like the resistor leads are mechanicaly sound (ie wrapped around the tags) then soldered.
Quality.
I picked this guy up at a garage sale for $1.00 and decided to finally bring him back to life; here I've hooked him up to an older ATX computer power supply to supply the ~5V, instead of wasting 4x 1.5V AA batteries. I also have an iDog in many pieces (somewhere on my desk) awaiting this hack.
When I connected his positive lead with the alligator clip it gave a little spark and a quick jolt to life! (dirty connection)
Note: using these 20 (or 24) pin ATX power supplies, you have to ground the green wire to switch-on the internal relay and complete the circuit. Thus, the fan kicks on, and all the leads supply power to the hard drives, etc. I didn't have an AT power supply on hand with the simpler on/off switch. In storage I have a few, however.

Cantex hack. F-mount body cap and a lens off an old compact camera epoxied together. The crude putty is there in hope of stabilizing the thing and offering better light (and dust) seal. The aperture ring still turns, to my surprise. Haven't tried taking it apart from the top now that the bottom is glued down.
