How Do I make a touch-sensitive Jog Wheel?
How Do I make a touch-sensitive Jog Wheel? Posted on: 05.02.2010 by Luna Coupal 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? | |

If you are decent with a screwdriver, soldering iron and other basic hand tools, there's no reason you can't do this yourself. |

| Arcelia Siebeneck 20.05.2010 | turns out I don't need to worry! 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. |
| robert chanda 18.05.2010 | Making a device touch sensitive can be done using the QTouch libraries provided for free by Atmel for their chips - no additional hardware required! http://www.atmel.com/products/touchs...?family_id=702 You get the choice of setting up buttons, sliders or more complex shapes just by running the libraries and sacrificing a couple of analog I/O pins. |

| Arcelia Siebeneck 18.05.2010 | 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? |
| Williemae Trau 25.02.2010 | this one too.. similar idea. It would be nice to figure out a way to adjust the sensitivity... hmmmmmmm http://www.instructables.com/id/No-I...ever-you-want/ |
| Williemae Trau 25.02.2010 | I don't believe 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. http://csmres.jmu.edu/geollab/fichte...etasimple.html 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. |
| Rebbecca Fennell 07.02.2010 | 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 |
| Jetta Giancaspro 06.02.2010 | This guy Rasteri made a touch sensitive scratch controller http://www.midibox.org/dokuwiki/scratchcontroller http://picasaweb.google.com/rasteri/Scratchtroller# |
| Luna Coupal 06.02.2010 | That's true, I may have to rely on the old touch screens for references. Thanks |
| Al Henger 05.02.2010 | Yeah, I believe it was in response to the V7, or w/e numark's new single deck controller is. |
| juan garcia 05.02.2010 | ^^lol, that sounds like the ns7 |
| Al Henger 05.02.2010 | Unfortunatly Draken, I dont believe 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". |
| Jayne Yellowhair 05.02.2010 | interesting |
| Al Henger 05.02.2010 | http://www.analog.com/library/analog...p_sensors.html Theres a more info heavy page. What about 1st gen ipod touch wheels? haha. |
| Al Henger 05.02.2010 | http://www.midibox.org/dokuwiki/doku...atchcontroller Not a ton of info on that page, but if you keep looking around you might find something over there on the midibox community s. 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. |
| Luna Coupal 05.02.2010 | If Only I had a VCI-300 to tear apart... |
| Jayne Yellowhair 05.02.2010 | I believe it's a great plan to make something like this, except I believe you are searching in the realms of the unexplored.. |
