With 21 six- and seven-year-old kids gathered around me on the floor, I built a CW transmitter starting with ten loose parts (three R's, two L's, four C's, and one 2N1613 transistor) plus a 9-V battery; a handful of clip leads, flea clips, and pieces of copper tape; and a lightweight wooden fruit box (the chassis). In addition I had a Morse key mounted on a board. As I assembled the TX I talked just a little about each part, trying to demystify everything, to show how this stuff isn't hard to do. I also worked in some general talk about ham radio.
