The laser clock.
This is a mash between a classical clock, mad laser pointers, 3D printed numbers an oil canvas and a rarely used way to show time. This project started years ago and has gathered a lot of dust since its first outing on Arduinos homepage. But now it is finished and hanging on the wall showing time as is expected of a clock.
The major difference to other clocks is that the clock arms are made from a stream of photons delivered from two central lasers mounted on stepper motors that are controlled by an arduino nano which again gets the time from a RTC.
If you need further details please contact me but how you build your copy of this clock is basically your problem. If you do build one please show me a copy maybe you have better solutions than me.
Best regards Stefan

Nicely done! Reminds me of an idea I had a while back for parts picking: Laser lines mounted above parts racks which cross over at the drawer where the part is located. Pulling out the drawer causes the light to be reflected back to sensors mounted with the lasers, which then swing to the next part. It strikes me that you could print things on the clock face and have the lasers point to them in turn. E.g. the day of the week, and maybe the month.
