Looking for an easy way to power your home-made gadget? Why not use a free USB port on your computer?
Take a look at the video below posted by YouTube user JeanOrwin to learn how to use a standard USB cable to power your self-built gadgets though a USB port. With only a few minutes work, you can strip the USB cable and isolate the power wires. After cutting away the extraneous data wires and copper insulation you’ll have two wires left that pump out 5v of electricity.
Fast forward to 3:06 to learn which wires to cut away and which to isolate. Once done, you can connect your modified USB cable into a free port on your computer. Touch the power wires to both leads of an LED – quickly so as not to burn the LED out – and you’ll see you’ve got power. Use a cheap luster terminal if you like to make the wires easier to work with.
