Because the controls needs to be available for the users they need to be somewhat environmentally sealed. Therefore, by using a Makey Makey and some aluminium tape, we created a robust and waterproof “touch” panel on the outside of the booth. The WS2812B led strip is controlled by the Makey Makey, and because it’s open source and Arduino compatible it was easy to modify the source code to also control the led strip based on key strokes. The led strip library we included can be found here.
The screen is a salvaged 17″ LCD with VGA input. To use this on a Raspberry Pi you need to use an HDMI->VGA converter. Easy!
Everything was mounted on a wooden plate cut into the correct dimension.
This installation will be available to play on to and including Trondheim Maker Faire 2014 (29.8 – 30.8). Come and play at M4 in Munkegata Trondheim, Norway!
