Re: Power to the Pi-ple
a plain old DC barrel jack
So, what standard is there for a power supply with a "plain old DC barrel jack"? There are a myriad of sizes - length, diameter, hole size... Some have the centre positive, some negative, some are regulated, some unregulated. Some are even AC.
Lets just shove a 48VAC barrel jack into a Pi and see what happens, eh? After all, the plug fits, so it must work. Right?
Much better with USB even if a small design error means some high-end PSUs will fail to power the Pi - but cause no damage to anything (other than a small dent in your wallet to get the very good value official PSU).
