How Do I make a touch-sensitive Jog Wheel?

[DJ Van Draken]

I've seen some designs for non-touch sensitive jog wheels, but I would like to make a touch-sensitive one. Does anyone know how to make a touch-sensitive jog wheel?

I believe it would consist of a single absolute encoder (14 bit or higher for 14-bit high resolution messages?) and an additional device that will change the output signal when the jog wheel is touched.

How do I cause the jog wheel to recognize my touch, without pressing down on the platter? What materials and devices are needed to complete this?

I think it's a great plan to make something like this, except I think you are searching in the realms of the unexplored..

If Only I had a VCI-300 to tear apart...

Not a ton of info on that page, but if you keep looking around you might find something over there on the midibox forums. Essientially, you need a way to make your jog capacitive touch sensitive... I'm not reallysure you you would do that, but I guess you could look into simple touch screen formats as well if you want. Like, the first gen touch screen pda/phones must of had a way to do it.

interesting

Unfortunatly Draken, I dont think you are going to find a ton of info on this topic, because, the large touch sensitive platter controllers are dominated by DVS. As Ean said on one of his earlier blog posts "we dont really see the point in making a controller that works *almost* as good as vinyl, at 3 times the price".

^^lol, that sounds like the ns7

Yeah, I think it was in response to the V7, or w/e numark's new single deck controller is.

That's true, I may have to rely on the old touch screens for references. Thanks
