Electric Watt Hour Meters!

American Science & Surplus is selling residential style electric watt hour meters. Awhile back I picked up this analog one from them for $14, but they also have digital ones for less at their tent sale going on this weekend.  I finally found some time to play with it and I managed to get it working.  I’ll probably turn it into a lamp or something!

Making the Gas Tank FIT!

Yesterday, I brought in my motorcycle gas tank and went to put it on the cycle. But IT DIDN’T FIT! The battery rack is exactly just a little too tall!

After talking with some of the other Makers at the space, it was decided the simple answer was just to trim a little off the bottom of the tank.

Since the gas tank is only really just a cover, mostly there for looks, no reason I can’t add dials and guages directly to the tank! Here’s the video:

EV Cycle Battery Rack – Part 3

Yesterday, I finished the upper mounts on the motorcycle battery rack. I actually ended up running out of angle iron for the top hold-downs, but the Makerspace is full of great salvaged materials. I used some of those computer tower case holders as the top brackets. They are sturdy metal and already painted black to boot!

Here’s some video of what I did.
