Now this looks like a fun little project - Ham Clock

Just the thing for my ham shack. I had been looking for a small 24-hour clock but this offers a lot more and I already have the equipment to build it - a Raspberry Pi and a small touch-screen. Here is a sample screen:

I love that it has the small thumbnail of solar activity in the top right corner. The clock can switch between UTC (Greenwich Mean) and local (touch screen remember?) and it shows not only your location but the location of the person you are communicating with at that time.
