Hall sensors and transistors.

Magneticus_Attractus

For the life of me I cannot remember or find how to use a hall sensor to turn on a transistor.

I always forget if I use a pnp or a npn for the output of the hall sensor.

With the hall connected to a PNP, the Pnp turns off when the hall turns on.

Now I remember why I use mechanical switches.



So I got things rigged on a small scale.

Like I say it is a motor/generator.





I did notice when I put the LED light on the pickup coil it is not until it hits a minimum speed that it starts to flash.

Next is to rebuild the capacitor bank for the double half wave voltage doubler.
