R.I.P for D.I.Y Or Long Live Open Source?

Embedded Geek writes "Scientific American has an article on the decline of science hobbyists. It presents a long litany of woe you'd expect about the "Good Old Days" (the death of classic electronic tinkering magazines, Edmund Scientific's corporate changes, and the cancelation of SciAm's own "Amateur Scientist" column), but also discusses some of the real trends in technology that have caused these changes. Declining manufacturing costs now make it cheaper to buy a telescope, radio, or computer than to build one yourself. The increased complexity of our gadgets doesn't help either (Ever tried to fix surface mount components with a soldering iron at your kitchen table? Don't!!) "

Personally, I found the tranformation of science amateurs into "quasi-professionals" intriguing. The Society for Amateur Scientists now holds sessions on how to publish research and how to claim tax deductions for home laboratories. Also, amateur astronmers are making great strides in comet discovery. Being that most of the people in the open source movement are software professionals, it becomes easy to draw an analogy between it and tinkering of yore.

    This is of course an extreme generalization, but just because the days of saudering irons and garages might be winding down, that doesn't mean that dedicated individuals outside of the academic and professional communities will no longer be contributing to the advancement of science.

Ingalls told amateurs how they could get personally involved in astronomy by building professional-quality instruments and carry out cutting-edge observations. Eventually Ingalls chose to broaden the column's scope to include "how-to's" from all fields of science. When he did, he also changed the department's name to "The Amateur Scientist."

    C. L. Stong
    Ingalls wrote his column for almost 30 years. When he died in 1954 the publisher selected C. L. Stong to continue the feature. Stong was an electrical engineer for Westinghouse and a master tinkerer who brilliantly extended the column, frequently peppering it with extremely sophisticated projects including home-built lasers and atom smashers. Many working professional scientists say that they first got hooked on science through Stong's amazing columns.
    In 1960 Stong compiled a book titled The Amateur Scientist, (Simon and Schuster) the only collection of articles that has ever been published from this column. However, limited to paper and ink, Stong could only fit in 57 projects. Despite being only a partial anthology, never being advertised in Scientific American , and appearing long before the rise of home schooling, Stong's book sold over 10,000 copies. It went out of print in 1972 and is much sought after today by amateur scientists.

    Jearl Walker
    Stong ran the department for over 20 years until he died in 1977. In 1978, Scientific American hired Jearl Walker, Ph.D. to take over. Walker had caught the publisher's attention thanks to The Flying Circus of Physics, a book Walker wrote which highlighted the fascinating physics of the everyday world. Under Walker's stewardship "The Amateur Scientist" presented fewer how-to projects, and instead focused on the physics of common phenomena. Walker's columns are still frequently consulted by educators and students alike.
    Walker resigned from Scientific American in 1990 after 12 years. Collectively, Ingalls, Stong and Walker account for 90 percent of all articles.

    Forrest Mims
    After Walker left, Scientific American decided to rededicate the column to hands-on projects and so they hired Forrest Mims III, a renowned writer of books for Radio Shack and an accomplished amateur scientist. They quickly learned, however, that Mims was an supporter of so-called Scientific Creationism, a movement that attempts to include the creation story of Genesis in biology curricula as a scientifically viable account of human origins. Not wanting to be perceived as supporting Creationism, Scientific American fired Mims. Mims charged religious discrimination and the story was carried through most major US news outlets.
    Although the incident didn't diminish Scientific American's commitment to the column, it did make them gun-shy about hiring another amateur scientist to write it. But professionals tend to be too narrowly focused in their own disciplines. The publisher invited many potential columnists to submit individual articles, and most of these were published under "The Amateur Scientist." But the magazine was unable to find anyone with both professional credentials and the incredible breadth of science knowledge necessary to recapture the popularity the column enjoyed under Stong and Ingalls. And without a regular columnist, the department languished, appearing only sporadically between 1990 and 1995. Most Scientific American readers stopped looking for it when they got a new magazine.

    Shawn Carlson
    In 1995 the editorial staff discovered the Society for Amateur Scientists. It's Founder and Executive Director was Dr. Shawn Carlson, a physicist and established science writer who had left academe a year earlier to devote his career to helping amateur scientists. Dr. Carlson took over the column in November of that year and immediately returned the column's focus to cutting-edge projects that amateurs can do inexpensively at home. Today, over 1 million Scientific American readers turn to "The Amateur Scientist" every month. The column has never been more popular.

      Of course it isn't complete though. The other day I started to vacuum the basement. The cleaner wasn't picking up much, so I examined the underside. The roller had a lot of threads and hair and stuff stuck to it. So I started to clean it. While I was cleaning it, the belt came off right in my hand. It had snapped, which explained why it wasn't working very well. I had never serviced a vacuum cleaner before. I examined the plastic cover, and much to my delight it was designed to snap off with the aid of a flat-bladed screwdriver. There were even handly little pictograms cast into the plastic that showed you where to pry. Once I had the motor shaft exposed, I knew I could replace the belt--if only I could find the right part. Here's the good part. I went to Fischer's Hardware. Not only is DIY and the mom-n-pop hardware store not dead, the mom-n-pop hardware store with no web presence of its own and nothing more than a listing with the chamber of commerce is not dead either. Fischer's has been in Springfield as long as I can remember, and I can remember a lot longer than I care to say. But wait, it gets better. Fischer's staff, unlike the huge box store staff, is always helpful. So I was not the least bit reluctant to walk in there with a broken belt and get either a replacement or a referral to someone who had a replacement (they referred for the fan motor for our bathroom). The guy in the vacuum department didn't have an official Hoover parts guide. When I said "do you need the model number" he gave me this look and said "don't get me started on model numbers". He took out some similar sized belts and started comparing them. When he found a close match, he handed me a Eureka belt and said "You can try this, and if it doesn't work use the yellow pages, get the part number from the mfct..." In other words, what I was too lazy to do in the first place and went to Fischer's to avoid doing. You can't get real-world expertise, honesty, and common sense like that from Home Depot. The belt was $2.18 and well... I had a coupon for $2.00. This was a no-brainer. Not having to track down a "genuine hoover part" was worth an $0.18 gamble. So I bought the little belt, got it home, and installed it. It was a little wider than the original belt, but it fit. The cleaner works fine now. I ran it for a good 15 minutes and there was no smoke or anything. Hopefully this fix will last, and even if it only lasts a few months I will happily buy another belt from the vacuum-cleaner hacker at Fischer's. That might cost more in the short run, but if Fischer's ever went away it would be a priceless loss.

The main reason they purchased a cheap telescope from a dealer, who incidently knew nothing about astronomy or telescopes, is because they also knew very little about astronomy. There are occasional exceptions, but when you buy a cheap telescope, you're usually sacrificing quality optics, and many who joined the society later discovered that the they'd purchased wasn't everything they wanted in the end.

    Just use a decent soldering iron that has a small enough tip and don't make the mistake of using too small a tip. A too small tip doesn't hold enough heat to flow the solder onto larger SMT pins.

    Also make good use of brush on flux and desolder braid. They are your friends when reworking SMT boards.

    When laying out your own PCB, SMT components let you get away with drilling far fewer holes and zero ohm resistors let you 'jump' over tracks without using vias.

    Another field that would be very interesting to look around is the high energy fields (tesla's patented projects, not any of that free energy-spook shit). Energy transmission seem sreally neat, but problems occur when they flood the full bandwidth with white noise (its what it does). The FCC doesnt like this ... research.

If you build a scope yourself, it will cost you a lot of time, but most materials are available at reasonable prices. Plus, building your own telescope gives you total control over the quality and design. With some effort, you will be able to build a telescope which outperforms most commercial telescopes.

    You can build a telescope mostly from parts you find at a dumpster: some pieces of wood for the base, a cardboard tube, a piece of glass... Take a look at the San Francisco Sidewalk Astronomers' website, for example.

    People have made high-quality optical paraboloidal mirrors from scrap glass, glass candle holders, trepanned discs cut from CRT-tubes, etcetera. I have ground and polished a 7" glass disc into a shape which surface deviates no more than 40 nanometer from an ideal paraboloid. All this takes is a lot of time and patience, and some basic materials. Remember: the first telescopes were built 300 years ago.

    The place where amateurs can't do much is in anything using low-power components. Radios, computers etc are all long-gone. But anything involving power components is still well within the reach of hobbyists. Hi-fi amps, power supplies etc can all be built more cheaply to a higher quality than commercial equipment. The simple reason is that if it's high-power, the components can't be miniaturised like low-power ones.

    The other place where hobbyist stuff scores is on anything esoteric. You want an automatic plant-waterer, or a touch-panel light switch, or anything out-of-the-ordinary which you can't easily buy off the shelf, you can build it yourself.

    It's very like software, really. A few large organisations (MS, the Linux kernel group, Gnome, KDE) have put lots of time into developing operating systems, window managers, utilities and office programs, so a lone individual can't hope to compete with that work on their own. But if the lone individual spots an application which hasn't yet been written, they can still crank that out and make it a success.

The main problem is that there's too many patents around, so you can unintentionally be infringing a zillion patents with your obvious ideas.
