I'm gonna make me some Robots!
It turns out that you can't buy these motors locally so I ordered some online. The most expensive part was the shipping, so I figured I'd buy a lot. I have a dozen coming which is overkill, so if anyone wants one or two let me know.
Hey, if I make some and you make some... if only there were some sort of competition that you could have between different objects to see which are fastest. Some sort of distance-over-time measurement, with a marked 'start' and 'end' points.
(I'm looking at you Dr. H.)
