Inside

Wanting to find out a little more about the unit, I decided to take it apart. It was a pretty simple process; remove the bottom two rubber pads and take out the screws beneath.

Inside you find the three buttons are connected to the PCB via ribbon cables. The switches use the same method as most keyboards with a rubber cone which when depressed allows a metal contact to connect the metal spiral beneath. The buttons are held in with metal U-brackets in both the vertical and horizontal axis which stops the displays being wobbly.

The displays themselves are quite small, measuring 32x32mm. They are about 5mm thick and are fully self contained.

To stop the unit from feeling light and cheap, there are two metal bars at the top and the bottom of the unit which also helps it anchor itself into place.
