Anyone who knows me knows that I like to stir a little bit in a good sort of way. My go to power supply voltage is usually 12 volts DC, 5 volts is also very common only because it is so available. When I was going through electronic school the teacher like to use ±15 VDC ( for opamps). And of course there is always 9 volts DC because of the batteries. 12 volts DC does not lend itself well to batteries IMO because it takes qty 8 1½ Volt batteries to make 12 volts. There are 12 Volt batteries but they are expensive and hard to get. Nor are they convenient, for most projects SLA batteries are not appropriate.
So what is your go to PS voltage, battery or not?
