For consumer electronics, no...but for something like an M, or other high priced long term high value item, it may be economically feasible...or something I'll undertake when I retire...again ;-) > I suspect the M6 has a simple uP to do the > entire job, I doubt there is any micro in the M6, I'd bet it's entirely analog. > and the M7 probably has the big brother with associated analog > drivers, etc > for the shutter solenoids ( or whatever you call the thingie that release > the mechanical shutter parts)....and a crystal oscillator... and then the > meter AE program. The M7 is more complicated, but that's cheap. Total electronics cost is probably under $10. I should see if I can get the schematics to the M6 and M7 and see what's there.
