Put this aside for a week while I screwed around with other things. Today 5V #wallwart and #breadboard DC barrel jack came
Not sure I dare power the #SBC from the wart (polarity if I ever swap the wart), but can use separate USB there
Plugged the wart + barrel -> VOM to check which pin was what. Yep, 5V. Unplugged....1.5V for many minutes
How large are the caps inside these things? If I unplug it and toss in a bin, is there any chance of a short causing a fire...OR WORSE?

Having a lot of problems with my laziness-imposed constraint of cardboard #engineering. (I have a wood/#machineshop in the barn, but do I use it? Do I hell.)
After hacking a bunch of #Lego gears/connectors to fail to get the stepper turning the barrel, I wanted to build the structure out of Lego as well. Stepper now a problem.
You have Lego motors, nitwit!
Happen to have #HBridge ICs in stock, so threw together a #circuit to drive it from the SBC. Works! Now write a driver.

Started putting this together, but now I have to impatiently wait to get into the room where we store the hot glue gun.
(first spelled that "hot clue gun"--could use one of those as well.)
