USB Powered Arduino Hack Defeats IT Dept.

Arduino key tapper keeps VPN login from timing out. Taps keyboard every 4 minutes. Uses small servo motor to actuate arm that hits shift key.

 

Acrylic case from Pokono. Other parts/servo from Sparkfun.

 

There might be better ways of doing this by faking computer that arduino was keyboard or mouse, but this was the easiest. :^)
