    Where to get touch sensitive volume sliders?

    Ok i have searched but i cant find anything exactly like what im looking for.

    Logitech has a new keyboard out in there MX line that has volume sliders that are touch sensitive. I want to find someone that makes something like this that could be used for numerous applications. Like built in to the center console or into the doors to control the windows.

    Has anyone seen anything like this before and have a link to it?

    thanks

    they are expensive; look at qprox ic chips. i have played with a few of there single button ic's (andi have 3 of there 6 button ic's sitting next to me as i type) great product but the sliders are really expensive

    I didnt know how expensive something like that would be. I just thought they would kick *** in a carpc set up.

    it may be worth it to hack that keyboard up. looks pretty cool

    edit:

    looks like you can get a refurb. one on ebay for 100 bucks shipped. Thats about the same price as that qprox chip but the drivers/software is already written for you.

    if you got enough qprox keys (maybe the 10 key chip) you could simulate a slider volume control by putting them in a linear fashion and writting some software that will translate it into a linear slider control. that should be relatively cheap <$20

    When I search for the QT401-ISG, which on the qprox website is their basic touch-slider, its only like $2.60 on Digikey. Am I seeing this incorrectly?

    Qprox ICs aren't expensive at all. Digikey has them for less than $4. You do need to build a basic circuit around it though, so it's not for everyone.

    I've not used the slider chip, but I have used the 6 button touch (QT160) and it's pretty easy to get going.

    I checked it out. Ive only built like one circuit board before tho. Although my brother has his minor in electrical engineering and has done quite a few. I'll see what if i can get it working.

    It would be so awsome to eleminate some of the ugly buttons on my doors and might make a great steering wheel add in as well

    thanks for all the help
