Gadget Freak Case #259: Gag Bomb Countdown Timer 25925

I created this Hollywood movie-style gag bomb that doubles as an alarm clock and a countdown timer. This is a fun project that you can build in a day or two. It is made using an 8051 microcontroller.

The project can be easily done with other microcontrollers or an Arduino, or you can even hack an old digital clock for this purpose. It is a fun gag that will look cool on your desk and can be used as a prank, a desk clock, or just a kitchen timer.
