  • Oh, Pete. For such a strong engineer, you should know that Nyquist said you must sample at GREATER THAN 2f. Equal to is not sufficient.

    See the comment from TheRegnirps for more info.

  • If you like the music it's Give Our Dreams Their Wings To Fly by Tim McMorris http://www.youtube.com/watch?v=6jhOoSkUzQs&playnext=1&list=PL801267DCE5B0D20F&feature=results_video

  • I described it thusly on Facebook:

    Cool song, fun video. How a circuit board is made... Steps - follow along in the video: "Board/part selection", "Solder stenciling - puts solder paste in the right spots", "Pick and place machine - computer controlled, small part placement", "Reflow oven - melts the solder paste which physically and electrically bonds the parts", "Manual part soldering - Human adds parts that can't be done by the pick and place", "Washing - Soldering requires flux which is acidic and needs to be removed.", "Automated Optical Inspection - They call it disco stu, makes sure the parts are placed right", "Dog QA - Tests board by smell", "Human QA - Tests board by hand", Packing, Shipping, Delivery, Unpacking, "Geek excitement - This is how we roll bitches!"

  • See the up close look at of the new table at the bottom of this article: http://www.engadget.com/2012/11/19/visualized-a-tour-of-ben-hecks-lab-video/

  • Looks like Ben is working on another one called Ghost Squad: http://www.youtube.com/watch?v=YHuNjz6P7kU&list=UUgeStlUnitobx8QcSxTw2aQ&index=3

    Looking forward to the Sparkfun build!

  • Lots of videos here: http://www.youtube.com/results?search_query=Bill+Paxton+Pinball

  • Nick, Ben Heck built a Bill Paxton pinball machine. Spoiler alert, this might be too much information that you would rather discover on your own. Check it out: http://benheck.com/03-16-2010/bill-paxton-pinball

  • I love all the sparkfun vids. For some reason, it's just a relaxing way to spend 5 or 10 mins.

    That said, in addition to the other comments regarding current measurement, I would also add that I was taught to be careful with the continuity test since it means applying a voltage to the circuit under test. These may damage very sensitive components either through too high of a voltage or reverse voltage.

    Which leads me to wonder: what voltage is used for continuity and what is the current limit?

    Also there is the caution of verifying that the meter isn't set to measure current when you are trying to measure voltage... Smoked two power supplies in a DEC cartridge hard drive in school that way...

  • New product idea! SparkFunyuns.... Funyuns (http://en.wikipedia.org/wiki/Funyuns) in the shape of the Sparkfun logo...

    I get a 5% cut for the idea.

  • This wasn't tested with the new version but assuming the new version outputs the same info when running the AHRS code... this is small Windows program with minimal dependencies that should run on most versions of Windows from XP SP3 on using WPF that emulates the python 3D display shown above. You need to have the ARHS firmware installed. See http://code.google.com/p/sf9domahrs/issues/detail?id=22

No public wish lists :(
