DIY hall sensor pot replacement

This short video demonstrates the Allegro A1302 hall effect sensor in its role as a voltage divider. This can be a drop in replacement for any mechanical potentiometer that is configured for use as a voltage divider (a three wire pot that uses all three wires).

This method allows perfect, noise free operation for your simulator controls. The device works across a 180 degree arc. The prototype shown uses a single 22mm ball bearing, an A1302 hall effect device and a pair of 1/4" x 1/4" Neodymium magnets (Available from Magcraft). The body of a hexagonal-body Bic pen (the common ball point type) is pressed into the ball bearing center and acts as the input shaft for the DIY hall sensor.,

I'm not sure what you're asking, but the magnets are oriented such that they attract on another across the gap made by the Bic pen body.

I just made a replica of your model, it works great! I'm planing to use it on my home made pedals (simracing). thanks for sharing!

You're quite welcome! I hope it works out well for you! The video you did is great.

can you use that also as a replacement for normal potis used for audio volume control? (normal potis tend to produce scratching noise after some time - i wonder if hall-effect potis could help here..)

Hello how are you?
please have the complete tutorial on how to create a joystick for flight?
since the creation of DIY Hall sensors up to the enclosure?

[fernandolopes]

The poles of the magnets are on the bigger surfaces, right?

[tijman]

wow, this is exactly what is was looking for, can you show more details, on the actual mechanism, i just ordered that exact same sensor to replace the pots in y pedals, thanks again

[fsim]

Thanks. The sensors are rated for 5VDC, so that's what you need to use.

It's great!
The sensor is connected to a 5v power supply or more?

Keep up the good work.
