For anyone watching this video years later, just wanted to say that placing a thin piece of aluminum between the electromagnet and the Hall effect sensor really helps if you’re having issues keeping the system stable. Before the aluminum I couldn’t output a square wave at all and the frequency would be in the 10k or higher. After the aluminum it was a square wave with about a 12% or so duty cycle depending on how heavy or how far the magnet was from the sensor, and the frequency dropped down to around 300hz. Which was a lot easier on the mosfet.

I was able to replicate. I had to change 2 things in the wiring diagram. First note is pin 2 & 3 should be swapped for the hall effect sensor. 3 is output not ground. I fried a few sensors learning that (at least for a EQ731L... Digikey on backorder for the 733). Second thing was for Op Amp logic. I had to switch pin 2 & 3 for the LM324N I ended up using. Swapping the hall effect output w/ the linear 100kohm pot made it so my magnet defaulted to being on then turning off when the levitated magnet got close to the hall effect sensor. They way shown had my magnet only turning on when the levitated magnet got close to the sensor (the total opposite ;.;). I'm a manufacturing engineer not electrical so no clue if this is my bad wiring, flip flopped wiring diagram numbers, or a difference in parts. Very cool video either way. This got me into electronics :)

However it is not very stable. The magnet levitates half an inch below the coil as it is a small magnet around 10x5mm so its magnetic field is not very strong to be detected by the hall sensor.

@MadScientist2678 ай бұрын
To a point you can adjust it just by biasing. There are a couple tweaks to this design that could give it some more fine tuned characteristics, but the only way I'd go with something at the bottom is if you intend to only levitate one specific object. If you want to be able to "hang anything" under it, it needs to be at the top. Unfortunately the field of the electromagnet is more "in the way" than useful to the hall sensor, as the only real field of interest is the one in the hanging magnet. One way to dampen the spiking the sensor sees is to put a small, thin plate of aluminum or copper between the sensor and the magnet pole. The eddy currents will dampen the spiking the sensor sees but the mostly steady levitating field will tend to remain unchanged. This also reduces stress on the MOSFET as it greatly reduces the oscillation frequency. Other tweaks come to mind but by and large this design is elegant and to the point, and indeed just works even as is.
