Thanks for the comments on the capacitor post yesterday. I thought the video was fascinating.
I grew up with a Dad who loved all things electronic and mechanical. He would undertake almost any project: fixing radios, fixing TV's, repairing cars, home repair, small engine repair, bicycle repair, woodworking, etc. He had this incredibly cluttered workshop with all kinds of things ... including capacitors.
If Dad was a 10 in his interest and ability, I was a 2 or 3. But both my brother and I loved doing his kind of projects. My brother built a TV from a Heathkit. Today TV's are so inexpensive that it would seem a waste of time to do that.
Essentials (for electronic kits) where we were younger: soldering irons, ohm meter, multimeter, etc.
Some of the fun things I built when I was a junior: alarm clock, crystal radios, electric motor, electromagnet, etc. Some of the fun electrical projects I have done: adding outlets to our bedroom (when we set up our water bed), exterior lamps on the house, etc. (Obviously working with 110 is a different thing than DC!). Years ago I helped a guy fix a key on his Apple II keyboard. This involved disassembly and soldering in a new key. Today one would just buy a new keyboard! Also I had an old daisy wheel printer (I think it was a DEC). I was able to bump it up from 300 baud to 1200 baud (a little soldering) and wire up a RS232 connection to my TRS-DOS computer. Another time Kathee (wife) and I soldered in a graphics panel into a Radio Shack TRS-3 computer (she was not pleased to participate in this as I recall). Another project (also involving my wife) was running a new wire up the steering column of our VW bug, installing a new steering wheel, a horn button, and a new horn. Kathee did a lot of the manual work on this.
If you have young children involve them in electronics and kit building. There's a lot to learn and enjoy there!
