A digital wall clock. This clock uses a LED display and a Raspberry Pi to show the current time. As long as the Raspberry Pi has a Wifi signal, the clock should be accurate. If it loses the signal for a while, it may drift. I am not sure how accurate the internal clock on the Pi is.

There is also a light sensor so that the display can be dimmed at night. For my use case, I did not end up using this feature. If anyone is interested, I can make a version without the sensor later.

The clock has keyhole mount on the back that is sized for a #8 screw.

I realize using a Raspberry Pi to display the time is a bit like swatting a fly with a sledgehammer, but the Pi is easy to use, and it only costs $10 or so.

I have marked this project as a 'Work-in-Progress' because the documentation may change. If you have any trouble with the assembly of the parts or setup of the Pi, let me know and I will try to update the documentation to make it more clear. I don't have any plans to update the hardware.
