This is just too good not to get several to play with. Alt+TAB Alt+F8 and the Terets version could be a real riot. I Love it. will be looking for these on e-bay.

Alt+TAB
Alt+F8
and the Terets version could be a real riot.

I Love it.

will be looking for these on e-bay.

I wrote an app that randomly (30% of the time) toggles caps lock when you press left shift. I figured that way it would be extra annoying because people would think they miss clicked. Anyways, you can get the app at my site officewarfare.net. This inspired me to write a software version. I wrote an app that randomly (30% of the time) toggles caps lock when you press left shift.

I guess with this, you would see the caps lock light blink. Or it could be pulsed.
It could make it so that it stops bugging when you press the scroll lock key and then say there is no problem :)

I use AVRs in my projects all the time and i've been wanting to add USB support to projects! The linked easylogger projects looks like the perfect starting place, thanks Hack a Day! :)<br>-Taylor This makes me really happy!
