Re: Is this a safe way to run 5v relay that will activate on 3v

I say just keep it simple.... so it makes troubleshooting much easier...

[RPi GPIO]------>[transistor switch]----->[5v relay module]---->[LED light]

just look for pcmanbob's numerous diagrams on interfacing a 5v relay to the RPi's GPIO...

"something" already knows how to boot from usb, "something" also knows how to boot over ethernet.
no... that is "something different"
the "something" you want is definitely none existent (at the moment)

Re: is it possible to boot over wifi yet?

"something" needs to run first before it can turn on the WiFi that "something" needs to be located somewhere.... and that "something" needs to command WiFi to get "something else" from "somewhere else" to command the RPi boot... "something"...

Re: four speaker output

if your car amp has Toslink or S/PDIF coax connection, just plug in a DAC that has those as output.

Re: Raspberry voltage requirement

RPi boards voltage input requirement is from 4.75v to 5.25v to operate properly. If the RPi's voltage sensor senses less than 4.75v even for a very brief fraction of time (only determinable via oscilloscopes), it will give out a low voltage warning Old-school linear power supplies usually employ LDO...

I haven't tasted it because I didn't want to break it this early but I guess I'll try it out.
