Why is everyone getting so excited over the Hall switching.?? As romero said its a hack and it works. You want to make a better one then do it. Use a fet driver and a power fet if you want but its very unlikely to convert a dead muller into an OU one. This hall device should be the very least of your worries.

Because people with some electronic knowledge should not foist off questionable circuits on the newbies. The idea should be to raise the level of expertise by proper example. What prompted this is one chaps failure to have this circuit work. This brought out the helpful nature of most fellow experimenters and an examination of the circuit in question.

The suggestion being not that a fet driver and mosfet was required but that such a circuit was just as easy to build as the hack circuit and would instill a great understanding of how these little building blocks work.

Two people are already using computer control, so proper fet drive is only an interim mode at that

Hi all,

Firstly, thank you Romero for providing the video and detail.

As I DO NOT wish to burden Romero with further questions - these are directed at the rest of us
in the hope that someone else may recognise items -

What type of magnet is that and, where do you get one? (that which is around the HDD plater)

Can I simply use a rotor with NSNSN or all one pole?

Is it likely to be NSNSNSNSN or all one pole?

Is that a FWBR at the back of the microwave oven fan core and coil?

and most importantly, is that MO fan coil original ? has this had another winding added that connects to the ??FWBR?? - if it is a fwbr

As I have already told you guys, I have taken the dynamo of the table, and hope to use
this long weekend to recreate and try to understand this experiment.

The key is the connection from the drive circuit to pickup coil/coils then over to the drive coil.

************** two coils wired in a special way **************

Kindest Regards, Penno

    Here is a link on how to make an inexpensive oscilloscope...hope this helps someone else out.

Or just google mini oscilloscope or mini DSO "


Thanks Tset, that is definitely the way to go...at least for me at this point anyway.
