Yet another "retired old guy" who enjoys tinkering and learning new stuff.
Been playing with electronics and computer stuff my whole life. Was a field service tech back in the 70's and 80's repairing dictation and word processing equipment. Two absurdly expensive product categories (by today's standards) which have both been superseded by the microcomputer revolution. Been in the computer and I.T. industry ever since.
Have extremely fond memories of Heathkit projects from back in the day. Built their o'scope, multimeter, TV and a bunch of other kits, plus actually learned most of my electronics from their training materials. Too bad that doesn't seem to be a viable business now, or at least not to the same extent where they could create kits of high quality components and superb assembly instructions for high-end electronics at prices roughly comparable to retail.
Ah well. Thanks to YouTube and the Maker movement, there seems to be no shortage of interesting things to learn and do.
