Do you have any samples of the different metals? If so, drill into each one and note the results. Then drill those dirty lumps and see if the results...

You're getting 60 ohms between two wires. I'd say you have three coils, each 30 ohms. You probably have one connection not making it, either at the Y...

A guy on a bike pulled into our restaurant one day for a coffee. His bike was not flashy, or well appointed or anything- what you did notice is that it...

There doesn't appear to be a start winding- all the wire looks to be the same gauge, and with 3 wires coming out I'd say it's 3 ph. If one has no reading,...

The short answer is- all of the above. Adjusting the height of the cutting edge will make a difference, and I would also check for play and flex in the...

We haven't heard from the OP again-

At any rate, there's one option which we haven't talked about- that is replacing the non-working 12 volt...

Ok, I looked at a few curves- there's one module, an MT-3608, that works from 3v and up- it's 80% efficient at 3 volts input, and that rises to 90% at...

How big is your panel- or what is the current rating? The specs on Noitoens module suggest that it could take as little as 2 volts and still provide...

The treadmill motors I've been using will run over 7000 rpm with full rectified line voltage. If the controller can handle actual DC, which would be the...

The only things I ever flew, besides paper airplanes, was a Cessna and a Navion. I was around 10 or so at the time. Neither one could carry a sheet of...

Wow- that magneto looks just like the one I hand-cranked to call home from Africa back in '69. The 'call box' stood at a corner where two roads crossed,...

Salt bath nitriding- almost something you could do with some beer and a few friends. Heat the ring, then stand around a circle and everyone pisses on...

Have to hand it to people who do these kinds of things. Soap box racing was a thing in my young days. I built my own car and raced it once, but I always...

The oldest way of doing this is to wire up a relay using one set of contacts to supply power to the relay coil. When you push the button, the continuous...

You're basically talking about an MPPT controller, which takes the output from a solar panel and manages it to provide an optimum power into a battery...

I once had an electric toothbrush that I converted into a lighter. I used a coil of fairly fine element wire and a microswitch to control the current....

I'll take a guess here and suggest that CB means circuit breaker- if those two wires are a circuit breaker you would wire one of them to a motor wire...

I once had the output of a color tv flyback transformer hooked into a piece of RG-6 coax. I had to strip the braid back nearly an inch before it wouldn't...

How hot does the shop get in summer? Maybe you need to consider a combined heat/cool system. I wonder if you could run a heat pump and minimize the energy...

I've seen that kind of thing used in starter motors as a retaining clip. One I worked on, the ring was so worn the parts came off the shaft and fell out...
