Is there anything new you have discovered recently that you would like to share?

It doesn’t actually have to be a new invention, but something new to you. It could be electronics or food or whatever.
I have been needing/wanting a dusk to dawn light on both ends of my house. My brother has been saying for months that he would install the device that would convert my light fixtures to dusk to dawn. I was in Home Depot and they now make dusk to dawn light bulbs! No special device necessary! Yes I bought them, in a regular bulb for my doors and flood lights for the ends of the house. I’m very happy with them. Who knew? So please share any new things you have come across.
