Hi Paul , Andrew
This is a very "low cost" and fast solution to monitor the speed projector.
The second way, as Andrew said in a tip before, is to get a small device with LED display, simply and well embedded inside projector . To give an idea, look at this (kit around 12 Euros) :

But.......... Many devices like this one are normaly used for "High" Fraquencies. So, may be the reed switch will not be used anymore, and has to be replace by a coding wheel showing 100 holes (result should be 25 fps x 100 ) for better accuracy and easier reading. The small device , as it is at this time , allow a new reading each second , which is slow perhaps... Also , I don't know if the PIC program can be easily modified to get a measure refreshing rate below 1 sec...
