Description

A Teensy based reverse geocache that will take her to some fun places before opening up to reveal a ring. The goal of the write up is to allow anyone to build their own and to actually document this process for later reference.

Components

1 × Teensy 3.2 Got for free from Paul himself from the Hackaday SuperCon 2015
1 × GPS GP-20U7 Module RF, RFID Hardware / Antennas that I got from sparkfun $20
1 × 2.2" TFT Screen Got for free from Paul himself from the Hackaday SuperCon 2015
1 × Wooden Box I built my own out of some 1/8" walnut veneered plywood
1 × 4" x 4" one way acrylic mirror I got a sample from here
