A new hobby that my son and I have taken up is Electronics. Not only is the topic interesting, but it is also educational for kids. The place that we started was with this starter kit from Conrad in Germany, but most electronics retailers such as Maplin Electronics in the U.K. and Maker Shed in the U.S. will have similar kits. The kit consists of assorted resistors, a 45uF capacitor, two NPN transistors and, fourLEDs, a small Bread Board, a length of single core wire and a battery connector. You’ll be amazed how much you can learn from a kit like this! In the picture below, you can see one of the circuits that we built using our first little kit – two NPN transistors connected to a 45uF capacitor and a few resistors that makes an LED flash on and off!
