    Retrotechtacular: Forces Acting On An Airfoil

    hackaday.com 19 Aug '14, 5pm

    What is an airfoil? Contextually speaking, it’s the shape of an airplane’s wing. In the face of pressure differences acting upon their surfaces, airfoils produce a useful aerodynamic reaction, such as the lift that makes flight possible. As the film explains, the ideas of lift and dra...

  • Open Source GPU Released

    hackaday.com 19 Aug '14, 2pm

    Nearly a year ago, an extremely interesting project hit Kickstarter: an open source GPU, written for an FPGA. For reasons that are obvious in retrospect, the GPL-GPU Kickstarter was not funded, but that doesn’t mean these developers don’t believe in what they’re doing. The first versi...

    First, remove the music, commercial music never EVER adds to a video like this and only causes problems for playback. Second, that is worse than what I get with a standard go-pro on a real motorcycle. Third, that is not a motorcycle, which is why it is massively unstable, it has no re...

  • The Remaining Hours Are More than Enough to Get in the Game

    hackaday.com 18 Aug '14, 8pm

    You have no such assurance. But what you do have is a posted record of what is known as “prior art”. If anyone came along later and tried to profit from your idea, you would have a record that you had come up with that idea first. It’s not particularly enforceable without having at le...

  • TFT LCDs Hit Warp Speed with Teensy 3.1

    hackaday.com 18 Aug '14, 5pm

    Hi, Paul here. It was never my intention to mislead you or anyone else. I’m a bit disturbed you feel this way, but I do see your point. Teensy 3.1 is a 32 bit ARM chip and Arduino Uno is an 8 bit AVR. Due has a 32 bit ARM chip approximately equal in specs to the chip on Teensy 3.1. So...

  • Pivena – The Open Source Raspberry Pi Case

    hackaday.com 17 Aug '14, 8pm

    The point of the RasPi is a hype tester. It lets other companies test bizspeak keywords in sales ads. I should really look into dumbing down a TV to only play audio (crappily), and not have enough processing power to display an entire image so that you get the unique task of going in ...

  • Melting Chocolate – FOR SCIENCE!

    hackaday.com 16 Aug '14, 1pm

    I’d be inclined to place a heated weight on top of the chocolate, and measure the temperature of the weight when it drops. Care would need to be taken to make sure the weight was the correct size and shape so it didn’t float, but I’m sure it wouldn’t be too difficult. Maybe a wide con...
