No more AA batteries!

Replace the AA batteries in your Apple Magic Trackpad with this board. Solder a short, stiff wire to the + terminal at the front end to contact the positive terminal inside the trackpad. Connect another longer stiff wire to the – terminal at the back end and wedge the wire in the channels near the outside to make the negative contact. Connect USB power to the two power input terminals in the middle. Run the cable out the back and replace Apple’s metal plug with a cork.
