Probably 1970s Pye radio/cassette, hacked to convert it to a guitar amplifier. Dimensions (in cm. excluding handle) L35 x H21 x D9. Has a tone control knob and I've added an extra treble cut switch as it's very bright when playing a piezo cigar box guitar through it. Runs on 4 x D type cells or 240v mains. Nice and loud and distorts well when cranked full. Has a battery level meter.
Long abandoned historic Tie Hacker Camp in the High Uintas. Tie hackers in this area were an important part of the building of the coast to coast railroad. Tie Hackers cut railroad ties from the lodge pole and other pine and fur trees in the Utinas and hauled them to the construction sights where the railroad was being built. Both the Union Pacific and the Central Pacific used ties harvested and shaped from this area.
I found a really simple hack to attach a pen to my Moleskine at: flickr.com/photos/xfletch/sets/1400422/
This is the Nokia 6250, heavy duty variant of the 6210 model. Features water- and dust-proof case, rubber inserts, sound level meter, automatic compensation of outside noise...but i don't care about all this!
Thing is that i needed that phone because of easily enabled "Network Monitor" that is, Field Test Mode. We are testing our mobile platform with network operator and for testing special software is needed. You can, of course, purchase the FT-enabled phones from Nokia but they cost 10 times the normal model. So i have modified it on my own.
Battery was completely dead and not repairable and it was not possible to get replacement so i took cheapest Li-Ion battery from the shelf, soldered it to the connectors and...the bastard didn't want to charge. After some reading and experiments with a digital multimeter i've found out that a resistor fixes the problem! Voila, i have functioning phone with Field Test mode.
Okay, the crop sucks because it's impossible to frame things right with the cameraphone, but still: this is one of the best hacks I've seen in a very long time.

From the IDEO London Superhuman make-a-thon. A day and a half of super-charged brainstorming, hacking, and prototyping.
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.
This is my hack for the last.fm hackday. It fetches the cover art for the last 24 albums I've listened to, sorts them by hue, blends them by colour together (according to the average colour of the cover), and places them in a 6x4 rectangle.
