Then current limiter and voltage regulator to feed the motor controller a steady 10ish volts.

Several of the box car designs are from me though.

First there was ME Models and now with companies such as BrickTracks, 4D Brix, and TrixBrix, competition is fierce. Even home […]

I’m always on the lookout for bright and colorful things to build and when I came […]

They’re extremely volatile; if overcharged, they explode. If over-discharged, they explode. If charged too quickly, they explode. […]

I’ve done some tricky stuff like decoupling the motor inside the shell from the pickups, and instead using the pickups to power a Bluetooth motor controller. […]

If they’re even the slightest bit off, you might as well use brass tubes.
