I saw somewhere on the internet a clock where the hand of the seconds moves at random irregular intervals, but averages out to 60 moves a minute. Extremely frus

I saw somewhere on the internet a clock where the hand of the seconds moves at random irregular intervals, but averages out to 60 moves a minute. Extremely frustrating to watch. Edit: here's a video of it running (somehow the seconds hand runs backwards) https://www.youtube.com/watch?v=HKU-zmNFSxw https://www.youtube.com/watch?v=HKU-zmNFSxw

The second hand isn't running backwards, the numbers run the wrong way.

  Keen eye, I did not realise at first glance.

  Neat! We built clocks with CAD and a laser cutter in my high school engineering class, and I remember cheekily making mine unqiue by numbering it backwards and/or without noon at the top

Although the movement of the second hand is quite erratic, it ticks exactly 32 times in 32 seconds, and so keeps quite accurate time overall. The clock started life as a cheap $3 clock from KMart. It's mechanism was kept, but the driver circuit was removed and replaced with an MSP430 microcontroller. ILAMtitan's code is designed to ensure that every 32 seconds it will tick 32 times, but the exact timing of those 32 ticks is variable. There can be as little as 1/4 second between ticks or as much as 24 seconds. Overall though it will keep quite accurate time.

  Both this and the clock above are quite, quite mad, and quite brilliant. I will have to buy some cheap clocks and start tinkering.

Reminds me of a wall clock in my high school physics class that would struggle to pass 5 o'clock and ticked backwards and forwards a few times on its rotation through each minute, despite keeping good time. Its struggle through each minute reflected my own struggle through each minute in that class, however.
