dmtrs Posted March 6, 2015 Report Share Posted March 6, 2015 Hello there, This is my first topic on this forum and feel good to be around. I am looking to start a project of a MIDI controller. The key "component" of the project would be faders and I would like to understand technology behind this part and be able to find suppliers. I have been reading a post from djtechtools on faders, but I was unable to understand the "keywords" if I may to look for the type of fader I am interested in ( the ones that skates along rails whilst conductive prongs stick out and tickle the conductive track). Could I get some insight on this? On the other hand, where do you people get your faders from? Is there any supplier you can recommend. Thanks in advance, Dmtrs Quote Link to comment Share on other sites More sharing options...
Phatline Posted March 7, 2015 Report Share Posted March 7, 2015 (edited) great link thankz! ... sometimes i got ideas to build such a optical or magnetic from scratch... the problem for me is the motor Edited March 7, 2015 by Phatline Quote Link to comment Share on other sites More sharing options...
novski Posted April 5, 2015 Report Share Posted April 5, 2015 Hi The most advanced Fader builder is penny & gilles. Like this: http://www.cw-industrialgroup.com/Products/Faders/Linear-Motorised-Fader-PGFM3200.aspx But thats an expensive part. So the most used one is the Alps : http://www.alps.com/prod/info/E/HTML/Potentiometer/SlidePotentiometers/RSN1M/RSA0N11M9A0K.html They also produce pcb mountable ones. What you need to know is that midibox MF_NG is working with linear Faders. If you don't know about midibox have a look to ucapps.de and the shop selling the DIY kits midibox-shop.com Best regards Novski Quote Link to comment Share on other sites More sharing options...
lis0r Posted April 6, 2015 Report Share Posted April 6, 2015 Wouldn't a DIY capacitive slider be easiest? Pretty much a capacitive touch slider, similar to http://www.elektor.com/capacitive-touch-slider-sensor-module-ebm014 , with a metal block taking the place of the finger, attached to the bottom of the knob.

novski Posted April 7, 2015 Report Share Posted April 7, 2015 Well thats certanly possible but also not easy to do if you are looking for a Motorized Fader. I can imagine some Magnetical Cap thats been moved throu a Motor from the other side of the Frontplane but still it would be a mechanical part and i think its more reliable to directly take a Fader with mechanical tracking then. Especialy in thaughts of my 5 fingers mostly stabalizing an laying on top of the next two tracks to fade gently the one my pointing finger is moving... 😄 But maybe for DJs with just a couple of Faders it would be more interessant, also because a DJ more or less does more Manualy than Automated.

lis0r Posted April 7, 2015 Report Share Posted April 7, 2015 No, I don't mean using touch sensors as touch sensors. I mean using them as the internal mechanism within the fader, triggered by a lump of metal attached to the knob carriage. If you want a concrete example, see the InnoFader. Should be easier than building an optical or magnetic fader from scratch. Quote Link to comment Share on other sites More sharing options...
lis0r Posted April 7, 2015 Report Share Posted April 7, 2015 As for motorisation - easy, take a page from the RepRap rule book. Spectraline: http://richrap.blogspot.co.uk/2013/08/3dr-reprap-delta-printer-part-2.html Quote Link to comment Share on other sites More sharing options...
