ALARM clock
Alarm clock not loud enough.
Removed sounder from an old car alarm, screwed it to the back and soldered it in.
Alarm clock now loud enough.

The electrombrero
Made in time for Millennium New Years Eve:-
Take two old sombreros bought when on holiday in Spain with the school.
Add 32 LEDs around the rim (red on the red sombrero, green on the green one).
Add a PCB inside the top (above head level) containing four chips and a handful of other bits and bobs, plus a touch of programming.
Result: a pair of sombreros with a 64-pattern, variable-speed light chaser on each. Still got them. They still work.

Another alarm one
Not content with my car alarm just making a racket if you broke in, I decided to add my own "enhancements".
Output normally used to flash indicators routed to a delay timer.
After a few flashes, delay timer would switch on.
Delay timer fed another siren. A LOUD siren. INSIDE the car.
Delay timer also fed a step-up converter that kicked out 500 volts AC to wires conveniently placed on the bonnet catch. A thief can't shut the alarm up without opening the bonnet, but can't open the bonnet unless he shuts the alarm up, otherwise he gets a belt off it.
I never felt the full force of this nasty beastie (although I did get a taster of it when testing the circuit, thanks to a wet soldering iron sponge) but one of my mates did when I asked him to pop the bonnet when the alarm was going off :-)
The 500V power supply is still lurking in a box somewhere...

» Stuff I've found
A friend of mine
found a bag of super-strength cannabis in Tescos loo. She did the decent thing of course: over the next few weeks the stash was wrapped in paper and incinerated.

Monging Mirror
A hard drive platter, slightly bent across the middle, makes an ideal "monging mirror". Look in it at the right angle and you'll see what your retarded twin would look like.
