(Be careful, don't shortcut the USB port!)

We will work with simple cheap USB devices, vacuum cleaners, LED lights, and hack the cable to the USB.





















This cable normally has 4 wires:
GND
5 V

DATA-

In the gadgets, there are only two wires used, the GND and 5V.

The 5 Volts form the USB is a good energy source, without bothering ever again about flat batteries!



 We can make a paper switch of button by cutting one of the wires.
The shape, the design has to fit your purpose. ANd use the LED ore fan, or motor to take part in the new gadget we make.

The only thing to watch is ....LED's are running at 2-3V so they need a resistor of 300Ohm - 1K.
Same thing with the motor running normally at 3V.

Pictures of the inside of the gadget:

Either the red or the black wire can be cut for inserting a paper button.

The motor and the LED can be used (without the casing) into your own "paper" gadget.
