After reading an April Fools joke we fell for, [Mortimer] decided to replicate this project that turns the common USB mouse into a powerful tool that can bring down corporations and governments. Actually, he just gave himself one-click access to Hackaday, but that’s just as good.
The guts of this modified mouse are pretty simple; the left click, right click, and wheel click of the mouse are wired up to three pins on an Arduino Pro Micro. The USB port of the ‘duino is configured as a USB HID device and has the ability to send keyboard commands in response to any input on the mouse.
Right now, [Mortimer] has this mouse configured that when the left click button is pressed, it highlights the address bar of his browser and types in http://www.hackaday.com. Not quite as subversive as reading extremely small codes printed on a mousepad with the optical sensor, but enough to build upon this project and do some serious damage to a computer.
