i would like one of the three actuator units. i'll send a pm.

Next up in the Steve "firesale"
#1 The Mirror Turret.
A 45 degree mirror, coated dielectric for red and blue, is mounted on a flat "table" bearing with very little play. Comes with a belt and a cog for mounting on the motor of your choice for limited rotation of about 170. With some work, you could do, full, fast rotations with this unit by adding a different belt. It has a removable flange on it for limit switches. It does reflect about 80% of 532 light as well. I bought these for making a clone of the "Horizonscan" projector the late 90s, which could scan around a room under computer control using a mirror like this. I also wanted to experiment with scanning down into them with lumias, and placing a white screen on them and spinning at a high rate to make a 3D display of the type in the 1977 issue of Byte Magazine. These came out of medical X-ray printers. These are the black item in the pictures. The bearing is world class, no detectable slop or play. If you dont want the 45' Mirror assembly, unbolt it and use the rotary table of the "turret" for something.
I have two I can sell now, however there are possibly four more in storage if I go get them across town. 50$ each + shipping, which was basically my cost "back in the day"
#2. The Beamline Actuator
These were medical x-ray beam attenuators. They have three maxon motor based actuators, The specially machined actuator arms have .3" diameter holes, with a small lip on them. The arms used to have lead and aluminum disks in them, which have been removed and will be properly disposed of. The idea was the disks shape the energy of the X-ray beam.
Now they would be great for gluing a burst grating and two line gratings on the arms, threading a beam down the middle, and making your own "laser rain" of sorts.
The arms rotate into the beam path. I have the picture set up to show all thee arms, and when in position they are centered and you can scan through all three. You can remove the actuators and use them for other things. These do not require high current like a classical actuator. They run off 5 volts DC.
Each unit has three actuators, and I have three units. This is the circular aluminum assembly in the pics. 35$ each whole assembly plus shipping.
Again, PMs please if your buying. First PM gets it.

suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.
