While surfing the Internet, I read about the new Geochron® Digital 4K . Before the Internet, this was the only way to see the Sunrise and Sunset on Earth in real-time and in sync with the Earth’s 23.4 degree axial tilt against the Sun. I searched to see if somebody had developed a similar system that would run off a local computer. What I found was a World Sun Clock , developed and described by Wesley, N2WES. It was an inexpensive alternative to the commercial model and was operated by a Raspberry Pi.
An easy new project for the shack was immediately started using a spare LCD monitor and a Raspberry Pi. Following Wesley’s information on the website, and some additional programming tools, I had my own World Sun Clock operating in about an hour. A future modification build will have the Raspberry Pi housed inside the monitor, where it can run independently using the monitor power supply. This project makes a nice addition to the shack and helps find a use for an old monitor.
