Looks awesome.. Joysticks these days, the majority of them are garbage.. Saitek have a really goofy external centering mechanism that makes everything stiff and bad motion, latest one I had was the Thrustmaster t16000m and that had a really goofy mechanism, left and right was good but stiff but when pulling back and then rolling fine adjustments are nye on impossible. I need to make something like this hehehe :).
Hi Jovial Pie! Thank you for your comment! You is right. The majority of joysticks have a goofy centering mechanism. Besides, it have another problem, with cheap potentiometers (not the case of T16000m). Fortunately, in the last years, new products, by new brands, are being manufactured, with pretty good metal gimbal mechanism e non contact sensors, like these ones: - BRD (avia-sim.ru/forum/viewtopic.php?f=34&t=758).

Awesome build! How did you design and define the cam geometry?
This one I make by try and error, based on photos from other CAM's, keeping in mind that the central part of the valley must be centralized.
Genio
Hi Juan Anibal Rodriguez Garcia há 13 horas, muchas gracias!
I'm working on a similar setup and using this as inspiration. if anyone wants my files when I'm done, let me know. (I'm making flat patterns for laser cutting as much as possible, and using aluminum extruded square tube for the central axis. I'm going to try and use those hydraulic cupboard struts for the springs.
Neat, i would like to have the files.
wow that great i want this files please
Do you have a cad file or even a jpg of the cam?
I don't have any CAD models of this one. Maybe this other project will fit for your needs: www.thingiverse.com/thing:2496028 kzhead.info/sun/e5enZJZ6eH-Blmg/bejne.html
how did you do the math to design the cam?
Hi Jae Orwin! I didn't do any math in this one. Just try and error.
What this cam mechanism called and How to design the cam profile? I’m searching for reference and principles but cannot really find anything like this so I’m currently hand drawing the cam arm. From what I understand the cam arm must open with same angle both ways right?
Hi WIRE! The proper name for it is 'cam and follower mechanism'. It transforms types of motions, like rotary motion into linear motion. If I'm not wrong CAM is the acronym for 'cyclic action mechanism'. Not necessary the mechanism arm have to work with the same angle in both ways. This could vary. I dont have studied it in calculus level and the physics behind it is complex. I just see several types of it, specially in DIY joysticks. You can design yours by try and error starting with some of the existing models. For further explanation about CAM's look these videos: kzhead.info/sun/e9eRh8mvnJWDf30/bejne.html kzhead.info/sun/hNRqhJinfZeVmok/bejne.html kzhead.info/sun/osd9qc1ub3iFn4U/bejne.html
@@jackcolquit Thank you for the reply! I’ve used basic calculation like moment of force and place contact point for every 10 degree, notice that as the roller moved away from pivot it have to lifts the arm higher than the short side to have same amount of force. Now I fixed force to deflection of cam arm it is easier than before.
And why show how he hesitates? That's a downside. An unsuccessful joystick turned out.
