>If anyone knows of any good books (or other references) along these lines, >I would very much appreciate pointers to them. Electronics is fun. If IBM have used the Intersil 7170 clock chip instead of the el cheapo 4 bit chip, they wouldn't be thinking about the year 2K crud right now. Course the 7170 cost 4 bucks more. Then again, maybe its a good thing they didn't know about it...;-) Melting a few parts, reading a lot of Elector (if its still printed), ETI, Pop Electronics, Radio Electronics, buying breadboards (non loaf type), getting a digital designer (Douglas Electronics) (I use Circuit Maker) goes a long way to learning. Books are fine to a point, but unless you get hands on, you're just paper smart. Soldering is also a fine art to learn and not as easy as some would like to think. I don't know if Jameco (California) is still in business, but they used to have a neat catalog that electronics buffs could drool over. Plus they used to sell a lot of little modules you could sort of "interface" together to make do things. I bought a whole bunch of Mr. Coffee innards from them one time to make some timers for a sprinkler system. It was cheaper than building them from scratch.
