Hi folks,
I've just finished building a mini^3 but I won't have a battery for it for at least another week. Is there any harm in running it from an appropriate wall wart?

Because I wouldn't be using a battery, am I able to skip (for now) AMB's checks if I have no shorts? Or could i do those with a 9V NiCad.. being careful not to plug the wallwart into the mini^3.
Thanks for the advice!

D2 and D3 protects the battery from "seeing" the output of the U2 regulator and vice-versa, and acts as an "or" gate, selecting the power source with the higher voltage to supply the amplifier. |
