LCD Contrast With a Diode

Some very long time ago I read something about using a diode forward voltage to feed v0 for LCD contrast. I tried it forthwith, and indeed it worked for me, too! Now it may well be that not all LCD look great at 0.65V on v0. YMMV

I believe I have found where I read that, if memory serves, at good ol’ Ray’s Hobby. Also known (by me at least) for the AASaver.

Speaking of AASaver, I fried mine. 🙁 Time to get a new one, and perhaps a part or two to fix the other one.
