Q³: Level 72 User Input

What you see before you comes courtesy of our own B72! He was kind enough to not just send these images my way (there are more after the jump), but to send them again since the initial email got disappeared into internet spam filter nothingness. Thanks man! He declined to send any sort of expounding information along, so I am just as in the dark as you all. But I have faith that it won’t take you all long to solve this mystery!

Last time we looked at a mysterious metal orb, and Ramon Z found the answer on this forum post. Nice interneting man!

If you know the truth this week, share with us in the comments! And if you happen to have access to any oddball sort of tech related items, or just a blurry camera and an eye for weird photo angles, please don’t hesitate to send your ideas in! Simply email HycoSpeed@gmail.com and throw Q³ in the subject line and I’ll get right on it!

  • Strobe! We use one of these to test our exhibits.

      These rods are machined to have a rectangular or square profile a certain distance from the end. This causes them to, when the top is plucked, oscillate with more damping in one direction than the other. The shiny tops then form Lissajou Figures in the circular cutouts.

      I've made a set or two of these. In order to make them match the Lissajou Figures on the graphic (pretty close to that chart), we use the strobe set at those particular frequencies and pluck the rods to check the oscillation in the two perpendicular directions. And then file it a bit to tune it. Takes all frickin' day.

        I like to think that this work station was created solely for the.. "whoah check that out" factor, not for any end use whatsoever.

    • We appear to have the very same one, actually. A Strobotac Model 1531-A made by the General Radio Company of Concord, Massachusetts U.S.A (home of the Concord Grape!)

    What the heck was that fiberglass(?) ribbed thing from a couple of weeks ago?

  • Slow_Joe_Crow

    Apparently I need to check AT on Sundays if I want to get an answer in early. My first guess at seeing a lamp head and a calibration knob was an early Strobe tach and Batshitbox has a far more detailed answer.

      You and me both…always a pity when, on the rare occasion that I know one of these, I don't see it until it's too late. Side note: I know this one because my folks actually have one of these that looks almost exactly like this in the garage — apparently it was a piece of test equipment at the company that my dad works at and was going to be thrown out, so he rescued it. I think his has its dial marked in Hz rather than RPM though. Maybe a more general-scientific-use model?

  • B72

    Bat nailed it! I figured Hyco would crop the photos, but no, he went easy on y'all.

    As an aside, I think the way the case opens is really cool.
