This is a question DIY Techno-hacks

Old hard drive platters make wonderfully good drinks coasters - they look dead smart and expensive and you've stopped people reading your old data into the bargain.

Have you taped all your remotes together, peep-show-style? Have you wired your doorbell to the toilet? What enterprising DIY have you done with technology?

Extra points for using sellotape rather than solder.

Probably Stolen Laptop Hack
I picked up a dinky laptop for a song off of eBay with the knowledge that it was "broken" and wouldn't boot. It seemed that the BIOS was locked out and there was a system password (which was strange, but I didn't know it) so some swift Google-Fu demonstrated that you would need to short circuit 2 legs of an EEPROM chip on the motherboard in order to reset the ID of the system, and then you could enter a new one sans unknown password.

So, disassembling the beast I propped the bare motherboard up with the monitor panel sticking off of it and fired it up. It took some time, but I found a chip with the right lettering on it which was about 4mm x 2mm. At the right spot I shorted the pins and.... nothing. I'm nothing if not tenacious. I shorted different pins, made sure I was getting it right. Made sure the paper-clip could conduct electricity (discovered it could when I dropped the clip on the motherboard creating a few sparks and angry noises) and was stumped. I tracked down the chip manufacturer's papers and learnt all about the damn thing. I knew what voltages went were and what pins were dead pins with nothing going through it. Four days of study and frustration I sat looking at the board and realised. I was looking at the wrong fucking chip. The right one was under some black plastic. Ole! Shorted the correct pins on the first try - Unlocked laptop! Woo!

Put it together (with some screws to spare - buggered if I knew where they went). Upon boot it became apparent that the laptop was from some company which I imagine the machine was stolen from, but that's another story...

screws
Those spare screws are known in the trade as "Pocket screws", because you bung em in your pocket after and nver use them for anything.

And when the pocket is full
You can trade them all in for a new soldering iron!
