    With all metal construction the cell phone won't work and WIFI will be useless due to the short distance, a cable would be cheaper, and the lack of a high speed internet connection.

  2. Junkyard on Where to Find Axles, Gears For Kinetic Sculpture? · · Score: 1

    Maybe it's because I was watching Junkyard Wars reruns today, but think about what you can find with automotive junk parts. For about $1 per pound you can get worn out transmissions and rear wheel drive differentials. (ok, that's $50-$75 per unit.) Add another $10-$20 per bearing if very free motion is required, suffer with the existing bearings, or use soft metal bushing bearings (babbit, brass, copper, bronze, lead...)

    With basic welding equipment such as a flux-core wire welder much can be done. With the 1-hp limit, or even 5-hp limit welding dis-similar steel alloys is of little concern. If you need a special gear you can weld using common steel and round bar making a round tooth gear. Not as smooth as an involute gear, but quite functional.

    If you need to support a heavy load, get the front suspension spindles out of a car or truck. Disk brakes will allow for lots of space to weld on. Bearings are, again, relatively inexpensive if you need the freest movement.

    If you need driven spindles use front-wheel drive parts or 4x4 parts, this way you can drive the center of the spindle.

    If this is too beefy or expensive you can invest in a decent drill press, and a selection of large diameter drills and reamers to match a selection of small shaft axle bearings. You will need to check specs, but they will ride on common diameter round stock, say, 1/2 or 5/8 inch, and be fastened, shrink fit, or pressed into a hole about 1 1/4 or 2 inch. Again check your specs and purchase accordingly. The required drill/ream dimension are probably some funny decimal to get the required results.

    So, recap:
    Purchase a wire feed welder. flux-core welders start just over $100. Yes, 5%-10% duty cycle would piss me off too
    Purchase and disassemble automotive drive trains.
    Purchase some basic machine shop equipment and a carefully selected set of drills and reams.

    You will probably NOT need a lathe or a milling machine, but if you can score them you will love them.

    A good bandsaw and/or a cutting torch would also be welcome

  3. Re:There is hope on Recovering Moldy Electronics? · · Score: 3, Informative

    I've not used that on electronics, but I did use it on an old car I had. Kept the "check engine" light out from a short in the wiring harness under the hood. I only used "corrosion block" every 6 months to a year or so. Got it at West Marine. I was put onto it for this purpose by a mechanic who serviced the local bus fleet.

    "T-9 Boeshield" is another product I have used in a similar manner. It leaves a film behind that is waxlike and can make a mess on glass and such. Works good for lubrication of moving parts around electrical though (power locks, same car) ...not sure about around optics in a drive. I got exuberant on the driver's side lock and took 3 or 4 tries with Windex to get the film off the glass.

    There are also some products that are essentially isopropyl alcohol in a spray can. Careful that you don't strip coating off the circuits. Some coatings are natural shellac which is alcohol soluble. In that vein, stop at the drugstore and get a bottle of rubbing alcohol. Get the 97% not the 85%, yes it costs 2x as much, so that's $1.50 for a pint.

    If you can't take this gear down to individual circuit board level, then there is little hope for it.

    Disclaimer: I've never cleaned a full system, just components like keyboards, mice, and a portable CD player. Mold was minimal. The keyboards and mice were usually from coffee or soda, and the CD player I think was excessive dust. The CD player failed completely after a second cleaning about a year after the first. The keyboards still live, and one has been cleaned 3 or 4 times now. (college was hard on it)

  6. power? on Satellite Internet Providers · · Score: 1

    If power was available, then wires would exist and a cable for data could be laid (or hung) cheap-like. If towers are 28 to 220 miles apart, where are we getting the juice from? Diesel? Last time I checked solar wasn't very effective in the northern latitudes because of solar penetration and weather. How long will a generator last to power said tower? How much fuel would it require? How much juice to push 220 miles through stinky weather? 25 watts ain't gonna likely cut it.

    That said, if the right piece of real estate could be had to put the right pieces of hardware upon AND have service capabilities and backup power provided without herculean efforts this may work.

    Said calculations are for line-of-sight frequencies over a theoretical horizon. With use of reflected frequencies and some ham radio capability a network could be set up, but I don't know the details, but service would still be spotty because the ionosphere "moves" changing where signals reflect to.

    Using multiple systems of varying capacity may be the best approach. Or pay to have a cable placed.

  7. Re:Lathes on Machine Prints 3D Copies Of Itself · · Score: 1

    HSS is awesome, and it can achieve very high tolerances, but the labor gets high. CNC used to be much more sloppy than manual labor. It is a recent achievement to get such high tolerances out of CNC, backlash in the drives screw up precision. Steel was the only cutting material for centuries. It will cut itself. It will need to be resharpened, but try that with a TiN coated carbide cutter.

    Most lathes can be used as a small bed horizontal mill. They can also be used as a shaper or single point broach using the feed to push a tool through the metal.

    I admit to these methods being in-efficient, but efficiency is not part of the argument.

    I also admit to needing a fair amount of manual labor. YES, I HAVE SCRAPED A LATHE BED, under the tutelage of a senior machinist. NOT FUN

    Also my wife was reminding me that her late grandfather built a lathe. It is in her mother's garage. That machine uses an oak frame, not steel, and is powered by a washing machine motor. To change speeds you need to physically remove and change the gears. I have looked at it, but never used it.

    You are talking about the argument for lathes. Metal working lathes are the only machine that can be used, after a fashion, to make ALL of its own components, and even make them to a better tolerance and standard than the machine being used.

  13. Scantron on E-Voting Undermines Public Confidence In Elections · · Score: 5, Insightful

    I personally like the little bubble sheets that get filled in. They are commonly called Scantron. Use a disposable paper mask that is pre-punched to match the sheet you mark on, and the voter takes it to the one or more machines for reading them in. Trackable, human readable after a fashion, simple technology that can be easily deployed for very large number of voters. Best part is one machine can service about 100 voting stations as cafeteria tables with dividers are all the voting stations are!

    I prefer voting on those than the touch screen units. Especially when I have to wait 20-30 min to get my time to vote, and I am in a relatively small voting district now. When I was in a larger district it was a 1-5 min wait to get you ballot, and a 1-5 min wait to scan in at one of the two machines.

    I also find that older folk are afraid of touch screen technology because they feel that it will break, or they are not comfortable with computers to start with.

    Unless you own a bar. As long as you pay for the tax on your alcohol, and the bank is happy with you, the govt don't care about profit. This is according to my neighbor who operates a bar here in Ohio.

    According to my uncle, a part-time artist and full time truck driver, who owned interest in a consignment art store for a while, you can show loss for about 3 years (this may have changed), then he had to show a profit, $1.00. He closed the store the following year. Mostly due to how the other artists were treating the business.

    Lastly, a co-worker at a former job was going thru divorce settlement. His ex wanted to keep her business, a bakery, which had his name on the loans. The judge ruled in his favor, closing the bakery because she could not show profit, nor a time frame to start making profit, and ruled the business a hobby.

    Of course I am NOT a lawyer, and need to do further research before trying to take a hobby to business status. Yes, I have a hobby that I think can succeed as a business. It may be better to stay a self-supporting hobby, selling off old toys to fund building new toys.

Small potatoes I know, but it was dedicated video ram. That system was on the PCI bus, and a circa 1995 system. If that machine were still alive a low grade web server would be about all it could reasonably be expected to do. Set up as headless I would want to have that ram useful, even if it was diminished in capacity compared to other swap spaces.

    Machines from that era were not capable of using system ram as video memory. That became popular shortly after in about '98 or '99. My understanding is those machines still had a small piece of dedicated video ram at the GPU, but could be assigned more ram from main memory.

    Internal combustion engines are also best when operated at one speed. It's called the power curve, there are actually several for every engine based on torque, horsepower, and efficiency. Strangely when set for any condition the peak of performance RPM is very similar in all cases. The same is true for turbine engines, but the curve is more like a spike when plotted against RPM.

    The ICE is used in all sorts of machines, and when trying to eek every last effort out of the fuel it burns, you end up operating it at the best RPM and designing the rest of the drive to that condition.

    De-coupling the engine from the drive-train is old news, they were doing the super cars and trucks like that 20 years ago. I wish I had the reference, but it CAN increase fuel efficiency under most conditions because the engine is operating as efficient as possible.
