warning: newb question ahead:
I'm breadboarding this for 12v relay power.
Removing the (-) side components just to get the (+) positive voltage for the relays. This part I can do, no problem...
...but then it occurred to me I'd have more available current with a paralleled secondary. My transformer is tiny at only 165mA so more current would be a big help - but there's no way to wire the bridge rectifier with a paralled secondary. I guess that's a necessary element to this design - to get 9v boosted for 12v regulation.
Should I just built this as is - leaving off the negative side components? And hope I can drive enough relays? (relays want 30mA) Or get a higher voltage secondary tx? Any thoughts or guidance will be appreciated. Thanks, Kato
