I was in need of a mouse twitcher, but could not wait for a few days. The fundamental idea is to have a USB device that prevents the computer screen saver from activating as there's constant mouse activity.
enCoRe III Full-Speed USB Controller (CY7C64215) from Cypress Semiconductor acts as a two-axis USB mouse. The cursor is automatically moved back and forth every five seconds.
No real magic here.
Design tool used PSoC Designer 5.4 sp1.
Ad hoc to the max. PCB made with dremel.
