Well, it's more than I could put in the Subject line.
At home we have a Lacrosse projection clock/thermometer in the bedroom. It's very convenient to be able to look at the ceiling to see the time and outdoor temperature projected up there.
I wanted one for the Sunstar and found a different brand on Amazon:

It arrived yesterday and is much nicer than our old Lacrosse. The kicker is, it will display temperatures from 2 more remote sensors. So, I can order another one and put it in the basement by the water pump when we travel and camp in freezing conditions.
I think it also has a freeze alarm for the outdoor sensor. It runs on 5 VDC and I have a USB A to barrel plug the right size to plug it into a USB port.
