University project: Physical prototyping – The One Key Keyboard

This is a physical prototype that I made as part of a critical design project. It’s a small painted wooden box with an arduino unit and a tiny lcd screen fitted inside of it. The box can be hooked up to a computer using an USB cable. A turn wheel is used to scroll through the alphabet as shown on the screen and a button to punch in a chosen letter  – a One key keyboard. 

Every letter counts.
