Power supplies for these projects? Answered
For this series of classes, I see that the power is supplied by the USB cable. However if we ultimately want a project to stand alone (without AC available), would an onboard LIPO or AA/AAA bank (like in the mailbox project) suffice for the remote? I'm contemplating a long term project that has AC available (to a DC power supply and a battery backup). Could you discusss or is there a separate class that addresses this?
