Oct 12, 2020 at 21:00 comment added Seamus @ChrisH: "Extrapolation"? What a nice word for it - have you considered a career in politics? :)
Oct 12, 2020 at 10:32 comment added Chris H I wonder if there was a bit of extrapolation by the book authors, going from a set of NiMH C- or D-cells (which would work quite nicely) to alkaline AAs which might boot but wouldn't be a good long-term plan

Oct 12, 2020 at 6:52 comment added Seamus @g491: Yes - it's sad, but true that much of what is being written is unreliable and inaccurate. I don't know if that's due to ignorance or carelessness.

Oct 12, 2020 at 1:41 comment added g491 @Milliways in light of your comment, would having a higher starting voltage be helpful? Like if I did 8 AA batteries instead of 6 and stepped down to the same 5V, would that result in extra current being available?
Oct 12, 2020 at 1:32 comment added Milliways In fact a step-down converter would allow MORE current than is drawn from the batteries. A new AA alkaline cell can source 450mA - but NOT for long!
Oct 12, 2020 at 0:50 comment added g491 Yes @seamus, in series. I wonder why it worked a couple times but not others. I just followed the instructions in a book on robotics with Raspberry Pi (ISBN 1593279205) so it's weird that it wouldn't work, but what you're saying makes sense.
