I went to several estate sales today (it's what I do on Saturdays, after all), but one was memorable. Some sales just jump out at you, and this one had evil genius/mad scientist written all over it.

The estate belonged to a man named Carl. From what I could gather, Carl was Catholic, diabetic, and from my wife's comments, must not have been married at the time he died. She mostly stayed upstairs while I rollicked around in the basement, which was tinkerer's heaven.

"This guy was just like you!" my wife marveled when I resurfaced once. Well, she's half right. I very much would have liked Carl. And yes, Carl liked computers and models and trains and didn't see any point in buying anything he could make himself. But Carl's knowledge of physics and other sciences went far, far beyond mine, as did his knowledge of electronics. I pulled out box after box after box of electronic components. Some of the stuff was pretty new, and some of it obviously dated to the early 1970s, if not earlier. It pains me to think most of that stuff is going to get thrown away, but there's no sense in me buying it, even for pennies on the dollar, when I don't know what it is, let alone what to do with it.

It's entirely possible that Carl and I did cross paths, sort of. In the 1980s and early 1990s, BBSing was a common hobby among people who enjoyed electronics, amateur radio, and computers. People exactly like Carl. For that matter, it's possible he might not have just dialed into BBSs, he fit the stereotype of a BBS operator like a hand in a glove. Who knows, maybe Carl ran a BBS I used to call.

Digging around Carl's work area, I found lots of different things. I bought some moldmaking supplies and casting resin, Bondo body filler, and some tools. Carl took care of his tools. But on his workbench, I found a single file laying there that still had metal shavings on it. Perhaps Carl died before he was finished with it and cleaned it. I found a brush, cleaned off the file, and could picture Carl looking down, nodding approval. I bought the file and the brush. Both were better than the ones I owned previously.

Unfortunately, Carl is the type of person our society has been trained to fear, rather than respect, especially during this decade. I found plenty of literature that Homeland Security wouldn't approve of. Instructions for making Tesla coils, and lots of instructions for making things that go boom in the back yard. I also found literature that dealt with alternative car fuels, converting cars to electric power, and generating your own electricity.

He was also obviously very interested in robotics and using computers to control things. In a spare bedroom, I found a pile of old Timex Sinclair 1000 computers and peripherals. He added I/O ports to most of them, and hacked another one to use a Texas Instruments keyboard instead of the cheap membrane keyboard that came with it. He must have used that Sinclair for programming. Another spare bedroom had a couple of barely started robotics projects.

Unfortunately, many people look at people like Carl, and are too quick to label him a deviant, or worse yet, a terrorist. The label is unfair. In fact, during natural disasters, amateur radio operators often are the people with the best information early, giving invaluable information to relief workers.

But the most important thing is the tendency not to think within the boundaries that "normal" people usually confine themselves to. Among his things, I found a book titled How to Patent Your Ideas.

Now I don't know what kind of ideas he had floating in his head. As far as I can tell, he never published any of them (I have his last name, and I searched out of curiosity).

But with all this talk today about energy independence, I think it's great that some guy in Crestwood, Missouri was thinking along those lines. I don't know if any of those thoughts turned into anything tangible or not. But frankly, that kind of work is important--much more so than the tinkering I'm doing in my basement, which so far has resulted only in some wooden toys for my son to play with, and metal toys for me.

We need some new ideas, rather than just buying everything from abroad. I know there are still people like Carl out there, but I hope they aren't a dying breed.

Now, if you'll excuse me, I have a sudden desire to go see what I can do with some of the tools I bought from Carl's workbench.
