Verto6 Posted January 2, 2012 Posted January 2, 2012 Hello evrybody! I'm about to build a collective (and rudders) for my own little sim-pit. The construction itself is nearly finished, but I really don't know which hall-sensor I should use. The collective beam rotates a steel axis, on that 2 magnets are mounted. I attached some pics - hope you get the idea! (And I have Leo Bodnars BU0836 usb-card and the Ultimarc A-Pac usb-card.) If anybody knows which sensor to use, pleeeeeease help! Thanks a lot, Verto [sIGPIC][/sIGPIC]
Kuky Posted January 2, 2012 Posted January 2, 2012 (edited) I remember when I was looking for HS to replace pot on HOTAS Cougar throttle I found all I needed was a pair of magnets and hall effect sensor (HES) that works on 5V or so and they are quite cheap... much cheaper then buying enclosed HS. The tricky bit is to found out what wire to connect and how to position magnets and HES... for me it took about 1/2 day to figure it out and get it working :D Edited January 2, 2012 by Kuky Windows 11 Home | Asus TUF Gaming B850-Plus WiFi MB | AMD Ryzen 7 9800X3D + LC AIO 360 | MSI RTX 5090 LC 360 | 64GB PC5-48000 DDR5 | 1TB M2 SSD x2 | NZXT C1000 Gold ATX 3.1 1000W | HOTAS Cougar+MFG Crosswind ... and waiting on Pimax Crystal Super VR headset & DCS MiG-29A release

Gadroc Posted January 2, 2012 Posted January 2, 2012 One other thing to keep in mind is you'll probably need to gear up the movement in order to get full range on a sensor. I have a similar setup and only register 800-1000 steps of 4096 available on my controller.
Verto6 Posted January 3, 2012 Author Posted January 3, 2012 Hi guys! Thank you for helping!!:thumbup: As I read at Mike´s website the Allegro a1301 seems to be best for this job. Do I have to mount the magnets in such a "u"-construction or can I just glue them to the outside of my steel axis (as shown in my pics) ? @ Gadroc: yes, I also thought about using 2 gearwheels and a chain between them to gear the rotation angle up... but there could be play between all this mechanical parts, so is there any other option?

Sokol1_br Posted January 4, 2012 Posted January 4, 2012 If Allegro A1301 is difficult do find you can use Honeywell SS405A instead. In this 2 magnet arrangement you need rotate magnets around the HALL, not in front. Like in classical "BIC" assembly: See this topic: http://simhq.com/forum/ubbthreads.php/topics/3225807/1/DIY_hall_sensor.html Sokol1
