psone screen 9 volt battery question

[Deck]

the psone screen takes 8.5V max, but my battery is 9V. I'm not sure where to get 7808 linear regulators (I don't want to make a digikey order for only one part), but is it alright if I just use a 1N4001 diode to drop the voltage, since I have some on hand? It won't be as consistent as an actual regulator of course, since it doesn't do any regulating, but it'll work, right?

I would recommend against it.

i did anyway and it's fine.
maybe i'll swap for a 7808 in the future

Well, yeah. It works, but I just think it's not a good idea to misuse components like that. I guess it's irrational.

well, i'm going to have to change it. If i plug in my charger while my screen is plugged in, the colors of the screen go inverted. I checked the voltage of my battery, and it changes from 9V to 12V when plugged in, since the charger is 12V.

mhm, that's weird, inverted colors come when it's not getting enough voltage usually. At least that's what I've heard

well, at least the screen wasn't fried
