This board is exactly the right size to replace the two AA batteries in an Apple Magic Trackpad. Connect the two power lines from a USB cable to the input jack. Connect a wire from the + terminal on the other end so that it juts out and touches the terminal inside the trackpad. Connect a stiff wire to the - terminal on the side and bend it so that it rides against the inside of the chamber. Use a cork to replace the original metal plug and connect the USB cable to a USB port.
The circuit is just a 3.3 volt (close enough) linear regulator with its related support caps.
No more AA batteries!
