Hi, I had a similar project in the pass. To gain more speed, connect the anode of the diode of the driving coil to the positive lead of a large electrolytic capacitor that can handle 250V and connect you negative lead to ground. Then see the magic.

what a fun little project, I am going to have try and build one now! Thanks. I subscribed looking forward to seeing more projects from you!

[@pugalstech]

Very nice

[@BrendanDempsey-d3s]

A cam or crank angle sensor would produce enough voltage to trigger the electro magnet with a transistor reed switches burn out in a short period of time even with a diode

[@kdvlder]

Very fascinating! Would it be possible to use a hall effect sensor in lieu of the reed switch? I'm not sure whether a discrete or linear hall effect sensor would be better, plus they would draw more current than a switch (obviously). Thank you for this video.

[@GarageScience]

Definitely could substitute a hall effect sensor. Current draw isn't so much an issue because for a pulse motor this small the limit on the amount of current draw is how much the coil can handle.

[@BushImports]

I don't know of anything smaller or even as small as that. pretty cool. Have you tried to see if it would generate any of it's own power?

En esrupidez siempre hay ganancia ,peor todavía es mostrarla sobradamente a otros,ahí,gana poder seguro a ojos a su nivel👐🏼🕊️

I am still trying to use just a transistor as an on/off switch. I dnt understand why you use both a npn and a reed switch.

[@GarageScience]

A transistor isn't absolutely necessary if you use a reed relay and a flyback diode. The first pulse motor I made used a reed relay without a transistor or flyback diode and the contacts on the relay didn't last that long due to constant arcing. I used a transistor because I thought I would end up using higher currents and the reed relay isn't rated for more than 1A. But the coils couldn't manage a stead state current much higher than 0.5A so all in all the transistor was just an extra component. I also wanted to show in the video how the same controller circuit could be used by just substituting the sensing coil with the reed relay, but maybe that just made it more confusing ;) . Thanks for the question!

[@gravelydon7072]

When you pulled the center part out of your reed relay it no longer was such. The center part is just a reed switch. Depending on the price locally, they can be had for $0.60 or less whereas that relay would cost a twice that.

Sweet!

Nice

[@earthsearchers7160]

Use super glue instead of epoxy, it also makes good bearing divets. Don't know anyone who would spray toxic, flammable WD on a clean magnet motor, just saying

[@chusdiaz9160]

😂😂 Por eso pone que es lo últimate ...Es lo última idiotez

[@Authoratah]

Did I hear correct, the power draw was 500ma....? That seems very high

[@GarageScience]

It is haha, I didn't run it for long at that high of a current because you could start to smell the insulation burning on the coil.
