gunrunnerjohn posted:Make sure the power pack is a regulated 4.5 volts. The easy way to do this if you're "rolling your own" is to use a 5V cell phone charger or similar regulated wall wart and include a series silicon diode to drop the voltage down to 4.4-4.5 volts.
Early on in my Miller sign life, I've ruined 2 or 3 signs by NOT using a regulated wall transformer. in fact, it was Miller's own transformer: his first one, not his more recent versions. I talked with him and he told me that his was not regulated (again, his first version is what I'm talking about) and that I should get a regulated one. I did and have not ruined a sign since, spanning maybe 8 years or so.
I have asked this question before and have yet to get an answer: I bought 3 transformers at a flea market, each 4.5V, but don't know how to tell if they are regulated or not since there was no directions included. Is there something on the transformer's case that means "regulated" without actually using that word??? I have 4 Radio Shack transformers and all of them have, on the BOX, the word "regulated" but only one has it actually on the transformer case itself.
