Re: (OT) repair tools: Autotransformers/variacs
I have a very old Strobotac and a booster that attaches to it and provides white light. My Strobotac is old enough to have a neon(?) light. It is absolutely fascinating. Among other things one can see how a bug telegraph key works.toggle quoted messageShow quoted text
Edgerton also devised some extremely high speed strobes for scientific purposes. GR built some and use to feature a picture of a bullet half penetrating a sheet of glass in its catalogs.
MIT people started some interesting businesses, another was Technicolor founded by Herbert T Kalmus. He formed a consulting company called Kalmus, Comstock and Westcott. they advertised in QST, among other places, to custom design radio equipment before Technicolor became successful. Of course the Tech in the name was from MIT.
You may know that Natalie Kalmus, Kalmus first wife, whose name appears on so many Technicolor movies, as color coordinator, had nothing to do with them at all. Her name appeared because it was a condition of their divorce settlement.
Talk about your OT

I have a GR Strobotac. It is fascinating instrument to have when studying repetitive mechanical motion. I know how brilliant Doc Edgerton is as well. I have a booklet GR produced for the Strobotac with many classic pictures Doc Edgerton took of things frozen at the critical instant in time when something remarkable just happened.
