Braeden108 Posted July 23, 2016 Posted July 23, 2016 So I picked up some Honeywell ss495a1 which I've heard are compatible anywhere where there was a potentiometer. So as a test I dropped the sensor into a logitech 3d pro (as a test, final position will be in a promicro based stick) I have some strong neodymium button magnets. Which I waved every which way around the sensor and nothing happened. I hooked my mutlimeter onto the positive and the signal and I got a solid 2.696 v. Again I waved my magnet around. Nothing. Where am I going wrong?? :helpsmilie: Light the tires kick the fires! [sIGPIC][/sIGPIC]
Sokol1_br Posted July 23, 2016 Posted July 23, 2016 (edited) Logitech and Saitek joysticks use ~3.5v in their circuits - it's said that this help in reduce electric noise in cheap circuits using cheap pot's. SS495A1 need around 5v to work. Solution: Instead plug the + and Gnd wires coming from the sensor in the points on circuit board what feed current for pot' - that supply 3.5v only - plug then in the point where the USB cable enter in the circuit board, as there are 5v. The wire for HALL sensor signal continues plugged in pot signal position. This article about install SS495A1 in Saitek X-45 is in Russian but is "readable' through Google Translator, and you will see the guy explaining this voltage workaround. http://sfw.so/1149033286-ustanovka-datchikov-holla-v-dzhoystik.html http://il2.skyline.kh.ua/forum/viewtopic.php?f=50&t=176 Just pay double attention to HALL sensor pinout, contrary to pot they dont allow voltage mistakes - invert + and Gnd wires, or "I love the smell of fried microcircuits in the morning, they smell ... acrid." :D Edited July 23, 2016 by Sokol1_br 1
Braeden108 Posted July 23, 2016 Author Posted July 23, 2016 Of course! Thank you so much help. Light the tires kick the fires! [sIGPIC][/sIGPIC]
Braeden108 Posted July 23, 2016 Author Posted July 23, 2016 No luck. I put 5 volts through the sensor and the voltage did not change between the signal and ground.I tested it every which way. Is it possible to fry them? I porbably put 5v right across the signal and ground. Also one them got nice and warm. Hahaha -$10 Light the tires kick the fires! [sIGPIC][/sIGPIC]
Sokol1_br Posted July 23, 2016 Posted July 23, 2016 post images If you supply +5v in wrong pin, think this apply: "I love the smell of fried microcircuits in the morning, they smell ... acrid." :D
Braeden108 Posted July 23, 2016 Author Posted July 23, 2016 Oh dear. Well mechanical pots it is for me! Light the tires kick the fires! [sIGPIC][/sIGPIC]
Sokol1_br Posted July 23, 2016 Posted July 23, 2016 Mechanical pot is OK, the major issue with then is that "joystick pot" - the ones with limited 30 - 60 degrees of electrical travel - virtually don't exit for end user consumer buy, are not available in Digikey, Mouser, etc.
