Hello. I'm hoping for some suggestions for a project I've been wanting to make.
I still like shooting film and have a number of very old film cameras, Zeiss, Agfa, Argus and so on. Most do not have a light meter and tho I'm good at guessing sometimes a light meter would help. I do have nice light meters but they are all bulky. What I envision is a very small inexpensive unit that would not be a woe if lost. I'm thinking of using an 08M2, either an LDR or a photo diode, probably LDR for simplicity. A lithium button cell, 2032 or smaller and some sort of a display. The display is where I need most guidance. I'm considering using a Nokia 5110 but it's rather big. The 128x64 .96" OLED is very nice but I'd have to use a larger chip and it's pretty complex to drive. I'm even considering the inexpensive 3 digit Voltmeters that Erco wrote about, they can be driven by PWM. Any suggestions for a simple to drive small display that's not too power hungry.
Thanks.
