About

300MPG.org is a web page and blog dedicated to people who take positive action to improve their own transportation options. From electric vehicles charged from the sun to just making sure you have the right amount of air in your tires, we can all make a difference to create a a better future, while still gettin’ around.

The site is administered by Ben Nelson, a self-professed tinkerer, who once almost accidentally built a motorcycle that gets the equivalent of over 300 miles per gallon.

If you have a great project that shows off what the common man (or woman) can do for a cleaner, more sustainable transportation future, let us know, and help share the story.

Do you have the electric smoth truck yet? I am looking for a controller for one of these

No.
I never had a Smith Electric Truck.
I helped out a friend go pick one up and get it started. I also used some of the batteries from it to run an original Ford Ranger EV truck. I do not have any parts from a Smith.

Hi Ben,

I’m looking to do a project that will require an epoxy finish on wood, and I’d like to spin it as it cures, the same way you did in your tankard project. https://youtu.be/meVnCJ9KbCI?si=JS5tcjqEgm6WswcQ

Can you please share with me who makes the motor and 90 degree reduced gearbox attachment? When I clicked the amazon link on your YouTube video it only brought me to a speed controller. I’m not particularly experienced with electronics in this manner, so if you could give me a sense of what motor, what gearbox adapter, what speed controller, and what power supply I’d need, and anything else that would be necessary, I’d appreciate it.

Hi Matthew,
The motor and gearbox I used was total overkill for my project, but it’s what I had! That was a motor from an electric wheelchair.
A better option if you are going to buy something anyways is simply a small motorized device that’s already sold specifically for rotating cups as they dry. For example: https://amzn.to/3ZPNmsX
Good luck with your project!
-Ben
