This is a case for a small gadget to put in your mailbox to light it up when you open to check for mail. This is useful since here in Sweden we only get a few hours of sun every day in winter, which means I usually have to check my mail in the dark.

Parts needed:
- 1x Sparkfun PRT-08808 prototype board
- 2x 3mm x 12mm screw
- 4x rechargeable AAA batteries
- 1x resistor of 1M ohm
- 1x resistor of 10-22 ohm (You'll want it to be around 60 mA to make sure it doesn't overheat)
- 1x 100 mF capacitor
- 1x through-hole 555 timer
- Lots of wire
- 1x NC magnetic switch (some stores get this reversed, you want the one that closes the circuit when not affected by an external magnet). I generally use Standex-Meder Electronics (MK04-1B90C-500W). Don't forget to get a flange if it's sold separately.
- Some battery contacts such as Keystone Electronics AA ones. The
