3D Vector Graphics Hardware Image Rotator XYZ 2ch

[Photonbeam]

Wow look what I found in the closet! It's a cool XYZ hardware rotator based on circuits designed by Bart Johnson. I built this around 1980 and it cost me thousands of $$. It has two channels of XYZ rotators, each has axis selection X,Y or Z, rotation speed knob, Forward/Reverse/Stop/Reset buttons. Gain and offset controls for X,Y and Z. Master image size knob, position joystick, Zoom knob. There is also a perspective circuit with Z axis input. You can use the Z axis output from your Pangolin card along with the XY out to produce a second set of XY signals with different perspective to send to a second set of scanners cross polarized to produce stunning 3D graphics when viewed with polarizing glasses. What was cool about this box compared to other analog rotators of that era was the hybrid digital/analog circuits. The sin/cos tables are stored on eproms and control analog multipliers with digital input. This meant that the rotation could be stopped anywhere and it would not drift. Still works great, only the power light is out. Anyone who is interested in old school lasershow gear will appreciate this. Input your laser card signals and produce some cool lissajou patterns live - even today! Built into a beautiful Zero box. $250 plus shipping.

that is all kinds of cool. would you happen to have any video of it in action?

No sorry. We didn't have video back then. (Kidding, but it was before camcorders became popular.) I hooked it up to a scope this morning and sent some test patterns through it with LD2000 to make sure it still works.
