The RaspberryPi is on the left, connected with my home-made GPIO connector to a breadboard, ULN2003 buffer chip and a whole heap of LEDs. There are 3 LEDs inside the Guinness glass, one red, one orange and a bright white one. The string of LEDs round the glass is set up to run on 5 volts.
The whole gizmo is programmed in Python and cycles through the 3 LEDs inside the glass to get a range of colours and then stuns you with the string of white lights coming on.
I tried to video it in action, but it was too dark for the 'phone camera, so I just took a few still shots of it and this is the best one.
So this is to you dad for giving me an acquiring mind and a love of anything electrical or mechanical and often both and for solving problems the lateral, interesting way.
