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.
- 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
- A 3d printer (hur dur)
- Soldering equipment
- Something to strip/cut wires with.
Printed with supports only on plate, and 10 degrees. Basically you only want supports on the big JST holes on the main box.
The big box will likely work with PLA. But the LED box relies on the PETG flexibility.
