Miwashi Posted February 9, 2022 Share Posted February 9, 2022 I was wondering how feasible this is, with the parts bring rather common. These are aluminum tubes and slider parts that people use to put together camera video rigs. Does anyone think there will be friction problems when sliding? As for measuring the axis movement,I'm thinking of attaching an audio fader below the assembly. Is it possible to do this instead with hall sensors, assuming the travel length is around 15 cm? Can the magnetic strength be measured over this distance? Link to comment Share on other sites More sharing options...
molevitch Posted February 9, 2022 Share Posted February 9, 2022 Camera rails like this are designed to NOT slide! Better to use something like this. https://www.amazon.co.uk/gp/product/B09MQB592F/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1 1 SCAN Intel Core i9 10850K "Comet Lake", 32GB DDR4, 10GB NVIDIA RTX 3080, HP Reverb G2.

Miwashi Posted February 10, 2022 Author Share Posted February 10, 2022 Thanks,in that case,do you think this sort of rail will work? Link to comment Share on other sites More sharing options...
agrasyuk Posted February 10, 2022 Share Posted February 10, 2022 I was about to suggest a linear bearing - mechanism taht was actually designed to slide. the rail can be a V-block rail, or a tubular rail. both can be had for a reasonable price. good luck !

Sacarino111 Posted February 12, 2022 Share Posted February 12, 2022 Hi. Look for the hardware of a 3D printer, as the rails and the traveler are deigned to do so, and they move very smoothly. In the other topic, 15 cms travel will be too much for a Hall effect sensor, at least for the ones I know. The fader potentiometer is the best choice, provided you can find so long ones (here in Spain I can find up to 6 cms, IIRC). The general idea is great, go for it, and shares some pictures, if available, as you are finsihing it. Saludos. Saca111 Link to comment Share on other sites More sharing options...
TomVR Posted February 12, 2022 Share Posted February 12, 2022 very much designed to bind! Before I build my simpit I did have a set of left over rods I mounted to the front of my chair and then put my joystick on a baseplate. Nice quick release, but ended up reusing the base plate for a camera rig anyway. Definitely not a bearing surface Link to comment Share on other sites More sharing options...
