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 AAA ones will probably work as well. They're pretty flexible.
• 1x Computer M3 chassis screw.
• Super glue.
• 2x JST female connectors
• 2x JST male contacts
• 1x 1W Power LED
• Heat shrink or isolating tape

Tools needed:

• A 3d printer (hur dur)
• Screwdriver
• Soldering equipment
• Something to strip/cut wires with.
