Fridge USB-BULB -- IceBoxChallenge

I am very pleased that this project is in selection 20 finalists out of 193 for the challenge IceBox Firstbuild / makerbot . I want to thank those who you vote for me. Winners will now be announced at CES2015 the week of January 5, 2015.

While looking for an idea for my first FirstBuild (https://firstbuild.com/rr/usb-bulb/), the question which always came back to me was “ how to supply my products in my fridge".

I needed a simple and long-lasting solution. I wanted everyone to develop their own apps and especially not deteriorate the insulation. This solution will allow everyone to change the possibilities of our fridge.

The system must be scalable with a USB port in order to supply a Raspbery, an Arduino...
First of all, it will allow to connect the LEDs to get the light lost by this change.

So I thought : “why not to use the power already existing in our fridge?”
Many of fridges use E14 lamps.
I had an lamp out of service. I decided to start from that basis.
