My background photo is a tiny part of my old tech collection.
From left:
Hidden behind my icon is the last remnant of the Spitz Space Transit System planetarium that I worked with. It’s a remote control box for the Moon and Sun projectors, both PTZ.
2nd: the world’s only imax film frame counter. Capable of rates up to 3k RPM or 6k frames per minute.
3rd(back) is a Xerox fax machine HeNe tube laser. An absolute pleasure to run with the cover removed.
