New Hall Sensor kits


Recommended Posts

Okay 2 things here what Sokol1_br is saying is to get the +5 volt from the USB supply of the USB into the joystick. I'll also have a look at the link to see what the difference is in the devices used.

 

The output voltage varies either up from (1/2 vdd) 2.5V or down from 2.5V depending on the polarity of the magnetic field north or south pole and the amount it varies depends on the strength of the magnetic field the transfer curve is shown in the data sheet.

 

So the magnets from say a HDD should be strong enough but it can be difficult to utilise both poles. For my cyclic I'm using small button magnets but I am still experimenting with how to derive the variable magnetic field one simple method is to arrange it so the magnet moves from about 10mm or so to right up to (almost touching) the body of the Hall effect device.

 

I also need to experiment with button magnets and I am thinking of arranging it so the magnet is close to the device and rotates on axis perpendicular such that in center both poles are close and as the magnet is rotated one or the other pole is bought closer to the device but I need to check this out as well there maybe problems with the transfer curve.

 

The biggest issue with this is that I may need to scale and level shift the signal to feed the control voltage into the existing controller either using analogue op amps or use maybe an AVR A to D the input signal modify the value then D to A for input to a controller. Of course all that could be incorporated into a single AVR but doing USB protocol in assembler might be a bit ambitious.

 

 

About the magnets , the best position i found is at the front and rotate the magnet clockwise and anti-clockwise works but it will not give me MAX high on the axis , this i need to figure it.

 

Of course i am not an electronics person , had done some way back in the 90's thats it :)

 

I just know to solder and check voltage ehehe.

 

But i will figure something out.

 

ABout your control setup , can you post some shots ? i need to make the collective with the throttle.

My cray hacks in pursuit if DCS

 

As for getting a positive and negative voltage change from 1/2vdd I tried rotating a button magnet (about 12mm by 3 mm magnets from a hardware store) and if I center the disk over the sensor sweet spot I can get the voltage about half vdd and if I rotate the disk so that it swings one way or the other I can get all be it shaky transitions going higher or lower depending on the pole I expose to the sensor.

 

BUT! I need to build a jig to test it as the distance set between the magnet pivot point and the sensor needs to be critically fixed although by hand I can get from 1.2ish to 3.6ish volts with maybe 60 deg rotation.

Control is an illusion which usually shatters at the least expected moment.

Gazelle Mini-gun version is endorphins with rotors. See above.

 

Currently rolling with a Asus Z390 Prime, 9600K, 32GB RAM, SSD, 2080Ti and Windows 10Pro, Rift CV1. bu0836x and Scratch Built Pedals, Collective and Cyclic.

Okay if your using a magnet assembly from a HDD, the flat section usually having a radius shape goes from north pole to south pole from end to end. In the case of the HDD the rotor {coil} would maintain critical distance from the surface of the magnet but move through the arc of the magnet structure based on applied drive to the coil. We want to reverse the mechanics and rotate the magnet assembly over the sensor. Whilst maintaining constant distance relationship and keeping the radius of the arc over the sensor. Easy. Right. :D

WHy a wooden collective base ? i suppose that is the collective.

 

And the extended stick looks exactly like the one i have modded using a 2 feet PVC pipe.

Yes the one is North and the other South. I do have two button type magnets but whichever works i am ok with. There is no coil , i have separated the magnets from the HDD

 

Oh yeah getting the arc on the sensor will not be an easy thing.

Try reduce the gap between the magnet and the sensor, this may improve the range.

Rgr, in fact i need to touch the sensor with it and that's when i can see the full axis movement.

 

Thanks.

WHy a wooden collective base ?

 

Relatively cheap.

Readily available.

Dimensionally stable.

Easy to work

Durable

Matches the base for the chair and cyclic I use.

 

And I don't need my TIG or MIG to join bits of it together simply use screws.

 

:D

 

I suppose that is the collective.

 

Yes that is my collective it's got some hundreds of hours of V-Flight time on it now.

 

And the extended stick looks exactly like the one i have modded using a 2 feet PVC pipe.

 

Yes this is a section of gas line a composite of nylon inner steel tube and a hard plastic outer very stiff but very light weight and just happened to be the correct inner and outer dimensions.

I get there is no coil now I was trying to illustrate the arc traveled by the coil in the magnetic field and this is essentially the arc and distance that you need to duplicate, see the article Sokol1_br linked it's a good solution for you I think.

@Fragbum

 

I am planning on a full metal collective , i don't know how it will be but i am thinking of attaching gears to the collective rotation point.

 

I don't know what base i will use , maybe a full aluminium body or wood but i am sure i will make the collective handle from metal if i get the right one else PVC,

 

Why i will use the gears for the collective is to keep it stable.

 

The idea is just in my head for now. But i will get there.

 

The main idea is to have for both fixed wing and helis but helis is now a much higher preference due to X-plane.

 

Let's see how it goes , still figuring out the arduino config at least for the switches and rotary buttons. I am not looking at a full scale pit but only for comms / Nav and maybe a few things more like the light switches.

 

I have a few toggle switches but i am not sure how it should be connected to the arduino , though i am checking a few designs.

 

Will adjust the magnets tomorrow or get more of the button types , the big coin sized ones.

Gear is unnecessary complication = backslash.

 

BTW - The best collective mechanism I see in forums around (including hover-control) is UO53 multi-disk brakes. May surpassed only by eletro-magnetic brakes.

 

file.php?id=4730

 

Is based on this Russian heli colective:

Need "perk" in this extended topic to understand the design.

 

http://avia-sim.ru/forum/viewtopic.php?f=28&t=630&start=630

 

A low tech version of the system, using a car handbrake as collective lever - and plywood pieces as brake. :D

I found an alternative , with an arduino uno and a MPU 6050 , it works perfect. the only thing is to keep the MPU 6050 leveled so i stuck it to the joystick handle.

 

I will use the hall effect on the other stick.

So MPU 6050 is working fine but i want to use the MH481 , but when i look at the center rotation of the stick there is hardly any room to fit the MH481, the rotation is very small. I was thinking using a matchstick and put aeraldite and leave it overnight

This topic should by locked, because the author are "out of business" - no longer manufactures "New HALL sensor kits".

 

 

Hey Guys, sorry for the late reply. As of now I am not making anymore kits. I would like to make them again but I don't want to fall into the "in 2 weeks" syndrome. I did design a much simpler hall sensor for the throttle that is a direct replacement for the stock potentiometer. Please don't plan on this though. If I start making parts again I will post on here. Sorry about this, its been great making these kits but it's just been physically difficult for me to work in my shop lately.

Anyway talk with rely4, he may have a (better) alternative for you:

Other alternative is GVL224 "MagREZ" sensor.

Where I can buy this mod ? 
 

my cougar throttle is very old… I need to calibrate every time
