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?
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.
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”.
I’m too lazy to look it up, but I know there’s a cheap way to make your own ribbon controller, find that and there’s your answer for a surface mounted device that will recognize your touch
I don’t think this would be very hard. Think of those metal lamps that turn on when you touch them. It has to do with the electrical properties of the human body.
This guy shows you how to turn on an led with a touch sensitive wire. I feel like this could be adapted to an all metal jog wheel. If I get some time I’ll build this circuit, test it out, and report back.
I want to mod my new EKS XP10’s so that the jog wheel is larger (possibly using a trimmed 7" vinyl record). Any ideas how I can make it touch sensitive easily? How did djDaB do it?
I may have some news on that for you shortly. I have stripped open my xp10 and I have the touch sensitive platter as a single unit. If I get time I will post photo’s of how to do it.
I’m in the process right now of desoldering the XP10 buttons but my soldering iron isn’t quite up to the job. I will be building a new enclosure, adding led buttons and also arcade buttons. Unfortunately I’m not the quickest worker as I’m very busy with work, a 2 year old daughter and a demanding (but very beautiful) wife.
If you are decent with a screwdriver, soldering iron and other basic hand tools, there’s no reason you can’t do this yourself.
my EKS XP10’s turned up earlier today… for a laugh, I placed a couple of cdrs on top of the jog wheel… turns out that the touch sensitive field works, even through 2 cds of plastic. This means that it’d be an incredibly easy mod to essentially glue/screw 2 cds onto each jogwheel to increase the size/usability of them.
overall, very impressed with the XP10’s - amazing value for money.
