Our buckets are echos Bascio with cardboard, but 3 sides of the cube of light and energy are made of cloth, to illuminate.
to get light reacting with the user in the buckets, tube to develop a usb switches, which work by charging cable plug any usb or device and that's what I intend to explain here.
First I needed a way to integrate a charger multiusb in the bucket into the bucket had a battery of 12 volts, so I could feed the light, the USB charguer, the arduino and the TV cube.
I use the Arduino, a switch and a servo to operate the trap door to appear usb, as seen in the video.
and now comes what seemed complicated, but easily solved,
The easiest thing to make a switch using a USB hardware is to divide the external usb female body into two separate halves, so that when you insert the usb male body, joints the two halves toguether. a wire in each half of the female creates a switch quite functional, You Can Carefully cut it using dremel.
In the video you can see, the door and the ligh sides working with the usb swiches (
