The Plot Clock is a DIY project that maintains the same tagline as life itself: both incredibly genius and completely pointless. This manifestation of existential boredom is a robotic clock that writes the time every minute on a whiteboard, only to erase it so that it can write the next minute. And on and on until the end of eternity. Watch it perform its meaningless task below:
O, Plot Clock! How you mock my life, erasing your own meaning with every minute that passes!
If you’ve got a completely pointless weekend ahead of you, why not do something genius with it and build your own Plot Clock? All that is required are the following tools: a laser cutter or 3D printer, 1 Arduino Uno microcontroller, 3 servo motors, 1 dry wipe pen, some M3 nuts and bolts, a thread tap, and an ability to choke back your own existential nausea. The parts to build Plot Clock are 3D printable, so you can watch one robot print the parts to build another robot that mindlessly counts down the hours until this purgatory called life ends as insignificantly as it began.
