Eclair ACL LCD footage counter for magazines

[Robert Latimer <themoviehouse@hotmail.com>]

Mark,

Interested in your ideas for placing an LCD footage counter on your mag, but 
how are you planning on triggering the counter?  Are you going to place some 
kind of tacho in your magazines too?

You can get low cost LCD readouts for about $8 that only need a 5 volt 
square wave to trigger them, but you're obviously going to need some 
electronics hanging off that.  You could make them so small and cheap you 
could place digital readouts on each mag, but I'd really like to know how 
you intend to rig up your clock's tacho.

LCD is fine for day and studio shoots, but if you ever film in low light 
those displays are very hard to read.  But you can buy them with suitable 
back lights at extra cost.  LED are also a plausible auction, nice and 
bright no matter.

Personally, I think your LCD would be better off counting incrementally 
rather than decremenatlly.  Otherwise you're going to need some kind of 
input to cycle your counter up to the right starting footage, and that's a 
whole new bunch of electronics and possibly an entry pad.  However, if the 
LCD just counts up, all you need is the reset button, which is already 
fitted.
