I a sense, I DID play with electricity as a kid. My father was an Electrical Engineer and a Ham Radio operator, so we had "stuff" around the house. I learned to solder at a young age. Some time ago, I realized that one of the best toys I had as a kid was the controller for my HO train set. It had a Speed (voltage) lever and a Forward/Reverse lever. Basically, it was a safe, variable voltage DC power supply. I could play with switches and flashlight bulbs and small motors and learn how they work. I've recently gotten back into Electronics as a hobby and I'm having all sorts of fun with Arduinos and Pis and such.
