Inspired by science fiction movies, this DIYer created a doomsday device prop complete with pull-pin, epic LED lighting, and countdown timer. When his microwave broke, he salvaged its innards to build this device. Overall, this project is a great way to improve your electrical, mechanical, and creative design skills.
Inside the device is an Arduino which coordinates the communication between the push buttons, clock timer and lighting effects. The bulky mass of electronics seen at the bottom of the device are high power hardware from the guts of the microwave.
Additionally, an old garden light was used for the “core” of the device and ancient tape recorder buttons were resurrected for pushbuttons. When you’re ready to build your own apocalypse device (or perhaps just an epic looking alarm clock), check out the project guide to get started.
