  • The elevator is made of demolished office furniture, some sliding rails, belts and pulleys. Small DC motor which used to rotate ink ribbon is now moving a belt with a pin. That pin is attached to the sliding parts. Battery is explained above.

  • First we disassembled some old printers to get a DC motor and a belt. The belt is used to move the bottom part, onto which the cache box is placed. Then some small furniture was demolished to get sliding rails for the bottom part to move up and down smoothly. Then we built the electronics circuit with LCD, a small custom-made keyboard and an Atmel microcontroller. The controller program asks for coordinates, and after getting correct responses to the questions, the motor is activated to open!

  • Sorry, werstehen nicht Germanisch... english preferred. The power supply for this cache is hidden behind the box, and it is 12VDC lead-gel battery. The location is given in geocaching site "firewood mystery Finland" - log in and try to find it!

  • splendid collection

  • Did you happen to shoot a video of how the elevator works? Also, what kind of batteries does it use? Nice job!

  • Very cool!

  • that would be great fo stashes

  • Great Idea,

    looks like you re-invented the geocacher atm in the woods !

    wondering if there is a sketch of the electronic circuit available and especially how the motor is triggered by the atmel thingy (atmega 8 i guess)

    Thanks in advance !

  • how did you make this?
