Golden Gnat Gyroscope

From the hours of 11 pm to 4am Saturday night I decided to make an educational video. Don’t ask me why.

I wanted to do some signal processing for my first video, mostly because it makes for a good video, and is something most people don’t know all that much about. So, I chose to explain how I made a support network for my golden gnat gyroscope.

Because I’m a bit awkward at lecturing it turned out kind of meh, but whatever, it works. If there’s a nice response I may just make some more, since this was kind of fun :-).

Enjoy! ∎

    Thanks for the clear and concise explanation that even I, a newbie to hardware could follow and understand. I especially have a better appreciation for the value of op amps now.

  2. Mike Snyder

    Thanks for the detailed explanation really liked it and learned some new concepts

  3. Curtis Desselles

    great video. i am trying to measure phase shift using analog circuits. any thoughts?

    • Just a difference amplifier, provided both wave amplitudes are the same!

    Good job, Adam. I’m looking forward to seeing more of your projects. I’m old-school and originally trained on vacuum tubes and TTL. I love analog and I can tell that you do too. Keep up the good work.

    Specs, or close to specs on the GG440 unit (a revised model is the 475 by US Dynamics)

  6. Hi,
    How the rate gyroscope can be used to stabilize Camera Gimbal in Remote Aerial Photography….

    This is a critical area where this can be put to use..


    • With very nice servos and a PID loop!

      A MEMs gyro should be good enough for that, though. Mechanical rate gyroscopes are good for bombing moscow from texas within 300 yards, so using one for a camera stabilizer is a bit overkill!

  7. Hello Adam,

    Wonderful job! I very much enjoyed your project presentation!
    Could you please flesh out the circuit detail for the very last element of your circuit? The D.C. level adjust Op amp circuit that you have implemented, does not show much design detail. This is an item that has presented a design challenge in the past, and I would like to know how you made this detail work.

  8. Very nicely done!

    A couple years ago, someone had documented the disassembly of a Golden Gnat gyro (they had no idea how these gyros worked). Based on their photos and descriptions, I summarized that the output windings contained data in both amplitude and phase – they had not considered phase.

    Your video confirmed every one of my suspicions, and filled in a few blanks. Thanks!

  9. Really great. Definitely looking forward to any others you put out!

  10. just a note of appreciation here.. thanks for posting such interesting stuff.. love the details on the gyro, about to spend some time reading more..

    This explained a lot to me. My brother is an engineer in ways and he does this kind of stuff all the time.
