This TNT Clock is shaped liked a stack of dynamites and uses common components to show accurate time.
It also randomly starts counting down to give a more realistic feeling of a bomb.
Wires are exposed to keep the aesthetics going that it's a bomb.
The attached files also include the schematics of the current implementation:
Main components:
An ESP32 module (wifi is not required)
A RTC module with backup battery
DS32314 character 16 segment LED display
HT16K33Three buttons to set time or enable DST
Assembly:
Solder the components based on what you have available.
The build is pretty straightforward: Both RTC and Segment display need to be on an I2C bus, and three GPIOs for the button. A regular arduino can be used, but I chose an ESP to be able to use micropython.
Improvise the visible wires -- the worse the better!
Insert M3/M2 Heat-set inserts.
Thanks to the RTC module the clock can be unplugged/replugged without losing the time.
The ESP runs a micropython firmware and is available for review on Github: https://github.com/prashnts/tnt-clock
The display and buttons are added onto the main body so they may be replaced with anything else you may choose.
PS: I'd not recommend carrying it with you at an airport! ;)
