It's a great find for me, thank you sir!Having a bit of fun with this, so figured I'd make a few posts to both show how this cool little guy works, and save anybody after me the time of sorting it out again.
Hi: This post does not match post #8. Maybe a wire color typo?Last bit, as it now sits on my desk finsihed
I took apart the gyro even though I didn't need it to work, but was now curious. Its acutally working fine, magnets and all. The base of the gyro unit contains 4 electromagnets connected in series in two pairs.
First pair are White + and Black -
Second pair are Red / Yellow and Red / Green
A third magnet rings the circular metal insert above the other four magents using Black for + and Black for -
The final electromagnet is a very large half circle coil right behind the mirror, with Black + and Black -
Final cable pinout for whomever else reads this off google later

Something else obviously controls these all seperately, as increasing or decreasing voltage to any given set lets you adjust the 'center' position of the mirror. As I didn't have that I wired them all up in series, and at 12 volts they put out a decent strenght field and could center up the mirror. I applied 18 volts to the motor which got it good and revved up, so it all works!
To display it there was no plan to have it spinning, but I do want it lit. I secured the gyro mirror with two easily removable dropes of hot glue. I went to the auto store and swapped out the 12 volt bulbs I'd replaced the 22 volt bulbs with for a set of low voltage (9 volt) LEDs.
I wired this into a 500ma 9volt wall power supply, and it'll pretty much run forever now without all the heat from the regular bulbs. End result looks good:
Your eye combines the two image into one when you view it, and it all appears centered when you do.
And the reason for the ability to mask that circle? When using the computing side, you mask the circle on the fixed old-style side since you see both at once. They leave the crosshair there, as that is still the final destination of your bullet, and it lets you see the lead the computer is giving you.
Kind cool, I like it
