Prototype of my Projector Controller. Based around a PICAXE 18X micro. The crappy DYNEX USB to serial converter that I am using does not put out a nice clean RS232 signal. So, the SP3232 chip on the left is handling the cleanup of both the programming interface (along with the Hex Inverter on the Right) and the second output (pin 6) of the PICAXE. PIN 7 goes high to red led to signal an output. The resistor array on the bottom right is an ADC keypad simulator. (http://www.lancer3.com/ADC%20Keypad.htm).
Part of a British Livens projector battery destroyed by German artillery as it was being emplaced.
Note the circular base plate, which was buried in the ground beneath the tube.

In motion picture theater the film is actually placed on a "platter" system as opposed to a big, vertical reel (like a home 8mm film projector might use).
The film is open and exposed to the environment of the booth - so it's important it's treated carefully and conditions are controlled.
The platters spin and a center set of rollers and attenuaters control the speed of rotation as the film is pulled through the rollers, across open space to a set of rollers on a center-column, across more open space to the projector itself.
The projector runs the 35mm film at 32 frames per second through a series of intricate rollers and guides - then back to the platter system where it's rolled up onto another platter.
When it's time for that movie to run again - THAT platter becomes the feed for the movie - and the whole process is reversed - alternating feed and take-up platters.
We also have a third-platter on every projector which allows us to do "double features" in each theater house. Two different films will occupy two of the platters while one remains free for takeup. A careful system of feed/takeup alternations allow one projector to rotate through two movies all day long and never have to remove the film from the system.
