Parts:
-Clear plastic (very tough) screw top water proof container, obtained in an airport souvenir shop in Japan
-4 AA battery holder
-7 leds
-Magnetic switch
-Bike light

Operation:
Use little piece of magnet to activate the magnetic switch. This causes the bike light circuitry to change state each time you hold the magnet near it, no need to keep the magnet there.
Cycles through 3 modes, blink1-blink2-constant on. Constant on seems to be PWM as it can be seen flashing when waved around.
Bike light (those red ones you put on the back of a bike) cost a whopping $1. Seems like a good price for a switch. If you're lucky you might get more modes.

Nice YC! I like the use of the reed switch. Very smart for H20 proof application! Nice combination and assembly of existing components. You need to get one of Darell's rare earth magnets. A tiny one will activate the switch.

Thanks guys!

Oh umm... this would fall under the "homemade" category. So there's really no modding part, since I made the whole thing up.
