Tirta, I think that you dont need shield, X and Y axis is not too close, and dont have another ferrous metal part around inside stick. Anyway, since you disassemble a defective CD/DVD-ROM drive (to get magnets) these things have a small DC motors, disassemble one - leave metal case and internal ferrite magnet - and use around your HALL assemble. Sample: Clarification to CH purists: Tirta no making any sacrilege putting HALL in your Fighterstick. Are a old gameport model "USBbified" with DIY Mjoy16 controller. BTW - Cost to replace 2 CH pots ~ 20 U$ + 10 U$ postage (last time I buy. And in my case + country fees, around 100%). Cost of DIY 2 HALL + magnets assembly ~ 10 U$. Sokol1

Hi Sokol1, thanks for the reply. metal case and internal ferrite magnet is that the circular one? is this for shielding? so I still need the 2 little magnet blocks near the laser for the hall sensor, right?

You still need the Neodymium magnets - these circular ferrite probable dont have necessary force to work with HALL. But make a test. I suggest use just for shield - in fact only the case of motor (or a piece of tube of ferrous material) is suitable to shield. But start without this, probable find that is not necessary. DIY HALL assembly is very flexible - you just need do some experimentation. Just dont mix + and - wires. Sokol1

A few pics from the final version of my A1302 based hall effect pot replacement: The first picture shows the control arm mounting plates that I made - they press-fit onto the pen body. They're VERY tight. The second pic shows the completed assemblies with the control arms installed. The third pic shows them installed in the Jentron MK2 gimbal. The original pots would jitter around center anywhere from 200 to 400 points. These hall effect replacements are rock solid. No jitter or spiking at ALL. They're stupidly easy to make too! g.

Hi Guys, I have finished converting my CH flightstick + pro throttle + pro pedal, all the major axis to hall sensor successfully. I use Allegro 1302, since that is the only hall sensor I could find in my town. The magnets are from used dvd/cd drive. I must say the result is very good, the HOTAS feels very smooth, very stable, very accurate and no more spikes! I would like to say thanks to you all for contributing to this thread especially to Gene for starting it and to Sokol1 for his special help. Happy simming!

Ok Guys, finally I manage to get some pictures here. Sorry they are rather unclear, I do not have my camera so I use my psp cam. so here is my CH HOTAS : Sorry I miss the Pro Throttle, it is still under the table. I have use this since the 90s, so now it is almost 20 years. here is the inside part: this is used to be a gameport joystick, I have made it USB by using mjoy16, thanks to Sokol1. here is the hall sensor and the magnets: I glued the magnet to a unused pots part, and put the sensor above the magnet. The magnet is very near, but does not touch the sensor. Sokol1, with A1302 there is no need for shielding the magnet, mine works just fine. Gene is right, after you know what to do, hall sensor is very easy to make.

Yup, very clean setup, congratulations. What is the sensor used? The position of the sensing plate relative to the magnet seems a bit odd to me.

thanks all for the kind words. I use Allegro 1302. I am sorry if the picture is not very clear, the sensor position is based on this picture: Thanks to Sokol1.

Hi Guys, I have just changed my hall sensor from A1302 to S495A My joystick is CH Combatstick. I have measured the angle movement: for x axis, it is around 60 degrees from extreme left to right. for y axis, it is bigger: around 70 degrees from extreme up to down. using this setup: with A1302, I can use it right away, no problem here. However, with ss495a, now I find its max angle movement is too small for y axis, I have not moved the stick to its extreme down position, but the sensor value has already reached 0. the same with max up position (around 4060). the maximum angle movement for s495a is around 55-60 degrees. Since my max angle movement for y axis is around 70 degrees, what should I do to make the angle movement of the sensor bigger? Please advise.
