NOAC Power Regulation?

Skidlz · Post by **Skidlz** » Wed Jan 21, 2009 8:57 pm

I'm building a Super Joy III NOAC into a standard project enclosure and I need to know how the power regulator should be built. I have what seems to be the original power supply (4.8v 100mA) though it measures 8.35v. It's going to be attached like this:

9v in being the power supply.
Is this correct? I've seen schematics that use caps from .1uf to 100uf and some are not balanced. Plus some don't use a diode.
Any help would be appreciated.
Thanks

SuperJoy uses, I believe four AA batteries to work. In saying that, it only just is happy with 6v. I have put my Li-ions onto the plug'n'plays, rated 7.4v (up to 8.3v on full charge as load is minimal) and all works fine. That powers the plug'n'play (which is what a SuperJoy is) and also PSone screen quite happily.

Yeah SJ's use 4 AA's but I'm not going to be powering this by battery. The power board brought the 9v wallwart down to 5 so I figure I should. I'm quite new to electronics but doesn't the 7805 protect against some amount of power fluctuation? I think they are rated 7v-35v while I would bet 35v would fry the NoaC. So I might want it just for safety.
Are you saying I can hook up the wallwart straight to the NoaC?

Thanks

If it's not going above 9v, you should be fine.
