Ambient Room Light Powered Pulse Motor

[00:00:01]Okay, I've got more really good news on this um 1.5 volt hall sensor made by this company here. This is the the uh part number and I bought this at mouser.com.

[00:00:18]They were very inexpensive and uh it's a little um SMD um small little chip there thing and very hard to solder up. But I did get that soldered up. There it is right down in there. And I hooked it up to this four coil um motor pulse motor. Now this is uh not like a easy spin. It's all north north south south facing um in repulsion all the way around. And the u little hall sensor according to the block diagram in the description here is a latching type of hall sensor in that this circuit goes into a latch mode. uh when the magnet goes by, it's omnipolar.

[00:01:13]Flips this transistor on, next magnet, whatever pole going by turns it off. So, it's a latching type of hall sensor that this is running on a little solar panel from one of these solar waiverss here.

[00:01:29]And I took it out of one of these things. I took the coil off of it. Then I broke the board off. And all I'm using is the top part of the board with the capacitor which is I think it's 450 microfarad 16 volt with the little panel. There it is at 4:00 in the afternoon.

[00:01:49]And it's a partly cloudy day.

[00:01:53]And this is inside the living room here.

[00:01:56]Uh ambient light and you can see the little solar waiver cat isn't even moving. If I turn this cat more toward the light, this will start going.

[00:02:08]This is the circuit scenario on that product right there. It's a coil with a very sophisticated complimentary transistor circuit with the same solar panel and the same capacitor on that.

[00:02:23]We've been using these for years and years and years and uh it's very efficient, but um it's not as efficient as a read switch, but this thing here for some reason is working pretty darn good for me. Now, these coils are not super fine. They're 34 gauge. Like I say, they're all one face coming out.

[00:02:47]And when the read switch is triggered or the hall sensor triggers, it turns on all the coils at the same time pushes the rotor around. And that's just suspended with a a magnet, a needle sitting on the top upside down on the magnet with a hole in the bottom with a brass rivet for it to run in and a good lubrication. But this is really good news. And you can see this little cat's barely wiggling here. It reminds me of granddad's um snowman experiment that he had running on a dead battery for years and years and years. I think he still has it. But anyway, good news. And uh if you can get a hold of one of these um hall sensors, they they come really cheap. They come on a tape and then somehow get that and solder it up and get that on some sort of a motor you've come up with. Yeah, I think you might be really excited about what I'm seeing here. And this is good news for anybody working on pulse motors. It's a hall sensor that'll work all the way down to about a volt with very little current required.

[00:03:57]Thanks for watching.
