HALL SENSOR MOD...

[sheperd]

Anyone use hall sensors? trying to mod my rudder pedals and ran into issues  could use some advise

[sheperd]

This is the wiring dia. for my mod, the center pot (hall sensor) is not being picked up. The center pot shows no ground, but the hall has to be grounded to work, is that causing my issue?



The dia below is how I wired it

I modded my CH pedals with the top diagram but I used the stock pots. Did you try contacting CubPilot? He seems to be the authority on Hall sensors.

Somehow I think the third output from the centre Hall Effect sensor is causing the trouble. What are the issues, that the brakes work but the rudder doesn't? Where does the diagram originate?

The diag. comes from the cougar site, and yes that seems to be the issue, I'm seeing a response on the brakes but not the rudder.

Think about it from the circuit's point of view. What is is to make of that additional input from the rudder sensor on to pin 4 and 5, won't it be the inverse of the value of the rudder position and hence cancel that out? That could explain your symptoms. Is there another ground available? What happens when you separate the inputs to pin 4 and 5? I take it you cannot leave the third wire unconnected as it is with the potentiometers?

I am just idly speculating mind you, I haven't looked on the Cougar site. Hope you get it working Shepherd!

pin 4 to 5 makes it see the 3 axis rudder, if you do not connect it you will only see rudder and no brakes.
as for the 3rd wire a hall effect sensor requires a ground, I thought about using a separate 5v and ground and just sending the signal to pin 11 but that is a serious risk, I cant afford another cougar stick!!!!!!

I should point out the rudder I have is a single axis, the diag. shows how to mod a single axis to incorporate brakes using 100k ohm pots...not halls.
I may have to resort to using a pot for rudder and halls for brakes...haven't tried that yet. but the object is to get away from pots altogether in my new pit.

Apparently there's no other ground on the DB15 connector.

If it is wired exactly as your diagram shows, you could try moving the rudder earth to the other side of the right brake (downstream of it, in between it and the earth). Might be worth a try.

I can try to ask my electronics friend for you if you wish? There will be a short delay, he lives in a different country to me.

[sheperd]

I'm not exactly sure what you are trying to say moving the ground? the grounds are electricy the same regardless of where in the circuit you connect  them, I'm Guessing I'm not understanding what you are trying to say. By all means please do contact your friend any help is welcome! and thanks!

Just so I am correct here on this Shep...you are trying to use three hall sensors right?

At least that is what I understand from the diagram and what I have seen guys do in the past.

[sheperd]

That is the goal, but so far I can only get the left toe brake working....I even put the pot back in center (ruder contol) and just tried the 2 toe brakes with halls. My thinking was the ground on the center hall was messing up the circuit ...the rudder works with pot and left toe brake works with hall sensor but the right brake is dead... I checked my wiring over and over and my wiring is ok.......  
My next step is to get 2 more 100k ohm pots and try it that way to test if the diagram is good but the sites I have seen even on cubpilots page the pinout looks good

[nrshida]

Swap the left and right brake sensors and test it again. If the fault changes sides you have a faulty sensor. Might even have two faulty sensors (centre one as well), don't assume anything if you have the means to test instead. You know the circuit works for the left brake, I'd test the other two sensors in that position and see if they're working first.

[sheperd]

you are a smart man, I replaced the sensor with a new one however is did not swap the input signal from 13 to 14 ...I'll give that a go.

What are you using for the hall sensors?

[Charge]

Just tried this with two Clarostat HRS100 sensors, other as rudder and other as toebrake and mixed those with one 100k normal pot as other toebrake, all connected to 5V and GND, and they work just fine.

Remember that when you are working with hall sensors they always need ground to work as they are not potentiometers i.e. adjustable resistors but sensors with internal circuitry. Also remember to restart the device after connecting a new pot/sensor so that it is detected correctly.
