This is a DIY binary clock. The case is small enough to fit in a pocket but at the same time large enough for all the components you need. It is equipped with an M3 threaded insert for 3D printing, so you can open and close the lid as often as you like.

The binary clock is running on an ATtiny 44 combined with a shift register and a RTC Module DS1307.
