You'll need as many resistors as you want to have countries. These are for the capacitive sensors.

Capacitor 0.1 µF
This is to debounce the rotary encoder module. You don't need it if your rotary encoder works fine.

Metal Pins
You'll need as many pins as you want countries. These are for capacitive sensing, so make sure they are conductive.

About this project

A video of the final prototype

Globe trotter is an attempt to make "holiday pictures viewing" less boring for people watching it.

The idea was to build a globe that would allow users to browse holiday pictures in a tangible and fun way. You would first pick an album (by touching a country), and then browse the photos by spinning the globe.

To make this project, I bought a regular globe from the store, and I pinned metal pins to the countries I visited. I then hooked a capacitive sensor to those pins, and I linked it to an Arduino.

I attached a rotary encoder to the axis of the globe, in order to be able to get the globe's position.

I then wrote a small programm that processes the data in my Arduino Micro, who then sends keyboard signals to the computer.

On the computer is a custom webpage that contains all the photos. The user can then browse the photos by interacting with the globe!

Here's a blog post I made about the work in progress, and here's the final project page.

This is a breadboard view of the hardware.
Note that the "capacitive sensing" part needs to be duplicated as many times as you have countries. Here I've only put 2, but normally in my case there should be 8.
