Yes, I have a chemical store room. Not my own but at work. Also known as the farting room because it has an awesome fume hood that you can stand near and have all the bad gas taken away. The female in our group was not aware that the six other members used this room this way until recently. Anyway, I digress…
I found this box in the back room while cleaning up. I’m sure with the knowledge base of our AT readership we can figure out what it is, especially since it’s written on the top of the machine. I have no good stories or info about it, but I just thought it looked cool.
So here’s the plan; once we figure out what a Photoelectric Demonstrator is (or even if we don’t) I have a question for you. What would you like it to do? I want it to be a mini Interociter?
It looks like a device that a an "electric eye" sales man would carry to prospective customers. It can power an external light source and its receiver (presumably the glass thing in the middle) receives the beam. When a certain amount of light is received (or is it when the light is gone?), either or both the small light bulb at the top and a buzzer can be activated.
In my head, the buzzer sounds just like the one from my cloth drier.
I enjoy sacrificing perfectly good virgins. The rest of that stuff is a waste of time.
Clearly the best way to convince people that there's nothing mysterious about the photoelectric effect is to enclose all the workings in a black box.
Set sensitivity to "kill".
Test & calibrate Cadillac "Auto-tronic Eye" high-beams?
Or we could pretend it's an early version of a HAL 9000
and wire it into a Speak n' Spell…..
It could be part of the control system for the mechanical man projects of the mid 20th century…

Did you ever find out what it is exactly? I recently found the same exact model, yet found only this website when searching tags of cenco and demonstrator (minus effect?).
Like texlenin suggested the only thing ive seen similar are old car headlight calibrators.
Thanks for the post!
