So I have a longing to have a pair of rudder pedals, due to my lack of money I cannot attain this item. I do however have woodworking metal works and tools to make a pair. I have a general idea of how to make the pedals themselves but putting in a potentiometer boggles my mind. Any help would help me and make me much happier.
A potentiometer is a little device that has 3 electrical pins on it, it measures the resistance between two isolated tracks on the inside, a little sled moves over these tracks and creates the full circuit. when the sled moves it changes the resistance(and thus voltage if your current is stable). this is then measured by a chip that gives a software signal and voila. You’ve got the eletronics down
Okay it takes a little more, but consider using a HAL sensor, this sensor measures changes in a electromagnetic field and thus only requires a magnet mounted on the moving part and no physical bits to wear(potentiometer degrade over time in joysticks).
I guess I’ve only given you a ton of questions more to worry about…
First of all, a Hall effect sensor registers magnetic fields, and is the sensor of choice for controllers, these days.
They can be bought really cheap online, and just need a magnet on the axis they are supposed to sense.
They are contactless, so they don’t wear out, and they are a lot more precise than a potentiometer.
I made my own angular sensors out of Allegro 1302 Hall sensors, a diametrically polarized hollow magnet and a bearing.
