Hackaday Links: February 3, 2019

Once technology that was only available to expensive design teams, and high-end engineering work, 3D printers are now readily available to anyone. Designing a physical prototype with a 3D printer is now something anyone can afford. Did I say anyone? Yes, anyone, even the people trying to build perpetual motion machines. Here’s one on Kickstarter powered by physics. It’s repelling magnets turning wheels.

The study and development of Artificial Intelligence began in the late 1950s and early 1960s. There were conferences, there were talks, colloquium, journals, the works. It was the beginning of a golden age. That came to a screeching halt sometime around 1985. Now, we’re in a new golden age of AI. There’s even a conference. It’s being hosted by [Jeff Bezos], as the alternative, public version of the MARS (for Machine Learning, Automation, Robotics, and Space) conference. Read that link. The phrase, ‘the Bilderberg conference of California’ is in there.

A new Project Binky? Can it be true? Yes, it’s episode 22. The center console is in, the dash is in, and the doors look somewhat finished. What’s the deal this time? A bumpin’ stereo. Wiring! Milliput! It’s English blokes in a shed doing fabrication, your favorite genre of video.

Aaaay, wait a minute. Have you heard about KiCon? Yes, there will be a KiCad user conference. It’s in Chicago, April 26th and 27th, and it’s all about KiCad scripts, settings, tools, techniques, and triumphs. There’s a call for talks, although you shouldn’t try to submit a workshop discussing the difference between ‘Kai-Cad’ and ‘Key-Cad’. That workshop has already been rejected.

Have a 25 meter satellite dish lying around in your backyard? Of course you do. Well, you can hunt for satellites with that thing and a USB TV tuner. The SatNOGS team has been working with a (radio) observatory in the Netherlands, and they’re getting radio signals from overhead satellites. Not bad, and there are, actually, a surprising number of unused large radio dishes out there. Luckily, they’re mostly historic sites.

    1. “Note that the units are expected to operate with a thirty year lifespan, as a result of a loss of energy in the system from the repulsive magnetic fields degrading over time, and are not free to produce, thus do not provide perpetual motion or free energy, and as explained below, operate in a manner entirely consistent with the laws of physics.”

      Not perpetual…just 30 years because the magnetic fields degrade. D’oh.

  1. “There’s no question that a prototype can be manufactured as designed with a large enough amount of funding, because an aesthetic prototype has been produced as demonstrated in the video, the only question is whether or not it works as expected.”

    So… “I built a thing that looks like a perpetual motion machine, now give me $5,000 so I can try to make it actually defy the laws of physics”

  2. “Pledge $10,000
    Handwritten Thank You & Phone Call

    • video created and shared with you, prior to public release, of the produced prototype described in the profile
    • donation toward expenses described in the profile
    • personal thank you email from the inventor
    • up to twenty copies of the book disclosing the inventions optionally name personalized and signed by the inventor
    • an optional thank you phone call from the inventor
    • this is the only level of support includes a handwritten thank you letter from the inventor which you are free to sell if desired”

    Oh wow, a handwritten letter! It’s all I ever wanted! Money well spent!

    1. What’s worse is his bio. “I wrote 3 books, and the King of the World said it was the best book evar, and world leaders came to my house to use the toilet, and I made a billion dollars out of software, I graduated from blah blah blah”.

      And then what’s missing, at the end of that, is “And I think I’ve invented a perpetual motion machine”.

      And again it’s just some silly rotating thing anyone in the Middle Ages might’ve come up with, and several surely did, bothering local merchants and bishops for endorsements, and asking millers for money to just-quite-perfect his machine that would mill an infinite amount of corn even when there’s no wind. Eventually either dying in poverty, lunacy, or a big red bleeding pile as his creditors catch up with him.

      Stuff any peasant could’ve come up with, using woodwork and commonly available tools. They had magnets back then. But somehow, people like this think “Well despite nobody in history ever managing to get this to work, despite the people who make Hubble telescopes and quantum interferometers and whatever else in the world; I, with no particular special advantage or even a high school science qualification, have somehow managed to crack it, just by thinking about magnets for 10 minutes.”

      Even leaving the physics aside, which you have to cos they don’t understand it, why do none of these geniuses ever think the above? They’re all the bloody same! A wheel, some repelling magnets, and some method of “blocking” the obvious failing in the system.

      It’s ironic. The people who know least about perpetual motion machines are the only people who ever claim to have invented them.

    Last I checked, there are countries where the mean income is 1-2 dollars a day. I know I am sometimes a little hard on you guys, but seriously, this reeks on a truly contemptible level.

    1. Are you unaware of the extreme poverty that some people live in? Or do you exclude people in extreme poverty from “anyone”? Or perhaps you believe that anyone who works hard enough and saves well enough can afford luxuries? Or perhaps you think that the amount of people living in extreme poverty is not significant enough to warrant consideration in such a discussion? Cause, none of those are good. I can think of other reasons you might have written what you did, but I can’t think of one where you come out looking good.

      It would be really cool if you edited your post and even cooler if you acknowledged the flaws in it.
