Clocks are relatively simple devices – they tell time, and most often sport a handful of other utilitarian features like alarms and radios. Rarely though, do you see a clock that will wake you up in the morning and also curse at you shortly thereafter. [Matt Evans] clearly thought that clocks need to pack a little more attitude, so he built his girlfriend a clock that not only tells time, but spouts off nasty phrases as well. What a lucky gal!

The clock was constructed using IV-17 VFD tubes, each bearing 16 light-able segments. It seemed wasteful to simply use the tubes to tell time, so [Matt] got busy adding other features to the clock. It has an alarm, a calendar that is always stuck on his girlfriend’s birthday, and an ambient light sensor to dim the tubes at night. It also sports a variable rudeness setting, allowing for mild insults when family members are present, and extremely foul language for when your frat brothers swing by.

He has plenty of pictures on his site, but we’re betting people will want to see schematics and some source code. After all, Mother’s Day is but a few months away!
