Have you searched for and read the other homemade motor threads here on PF?

Draw a schematic with two batteries wired in parallel. Then break the connection between the positive terminals and insert two resistors in series where the connection was broken. Then make the right battery a variable voltage source. The node between the two resistors and the negative battery...

They all buzz. Watch a few YouTube vids and you will see.

I have not verified whether the device discussed in the video is identical to my unit but it is the same company. It does not surprise me that the unit in the video is designed the way it is based on the symptoms of my unit. - This afternoon I allowed plenty of time for the unit to warm up...

I have had a Vevor brand ultrasonic cleaner for several years. I purchased it new. When I first purchased it I tested it out by filling the tank with water and turning it on. For about 30 seconds nothing happened but then it made the familiar buzzing noise and appeared to be working. As time...

He almost has a shock absorber. Just need the spring.

While I like dogs the only experience I've had with what I assume is in the pic was not a good experience. If those packages disappeared I'd blame the dog. ;)

I don't know what this extension board is. Troubleshooting involves eliminating everything possible while still having the failure exist. It's my opinion you have not done this. You seem to have done the opposite which is eliminating as little as possible and then making assumptions about what...

You only have one appliance that you get a tingle from and only when it is turned on. My suspicion is that device is faulty. Does it matter if you plug it into mains on different circuits in the house? I know the complexity and size is limited in India so maybe you have only one circuit you are...

I've put as much effort into this as I care to. The claim of 2 billion bird deaths a year in the USA caused by cats is absurd and I've pointed out why. - In jury duty in the US jurors are allowed to dismiss testimony from a specific witness if they consider the testimony to be unbelievable. Not...

I'll agree there is a huge difference in cats when it comes to their ability to survive. I guess nature has probably selected out the poor ones in my case.

Agreed, except the rat part. I've seen a cat take rats out quite easily. That's not to say half grown cats will not exercise caution. Full grown cats in my experience have no trouble. - The thing with rats is that they are generally smart enough to move off the premises if the cats start...

As I often say, you do you and I'll do me. Maybe that's not a familiar thing across the pond. I can tell you this much: Our cats generally have no problem with rats. And I fail to see the concern of a humane way to deal with rats or mice. The preferred method (not mine) to deal with mice in the...

You really did miss the point of my post. What do you suppose the coyotes, etc will eat when the cats are gone? Right now the cats survive on the rodents. Eagles and hawks do too, as well as a cat now and then. Coyotes and fox mostly survive on rabbits, gophers, etc and now and then a cat. With...

Where I come from in the US hawks, bald eagles, coyotes, etc prey on the cats. If the feral and outdoor cats that keep the mice and rats cleaned up leave, I will have something worse. I've read that fox will take a cat but I can't say from experience. Right now the fox are close enough I don't...
