Stribe1: Touchstrip + LED Bargraph Display

Euphonix should replace the faders on their system5 consoles with touchstrips. Design-wise, that would be a damn slick improvement.

The product simply uses 2 Soft pot Touch potentiometers..... You can find them at sparkfun for about 15$ each

The complete schematics, code and everything is available at CuriousInventor com. The softpots are 170mm lengths, $16.89 each, not available at SF, but at our store.

omg awesome man

omg i would kill for a stereo with touch controll buttons like that :O

You should mass produce this! Pair it with a set of speakers instead of a knob or wheel.

thats awesome. I googled 'touch strip potentiometer' and your store was they very first link. I see you have the ipod style rotary pot's, also.

oh, and nice touch including a ruler in the photo, along with the product.

but I'm curious about the description. is it an actual potentiometer, or a device that acts like one with the right micro-controller?

actual potentiometer.  You put 5 volts across the outer pins and the middle one divides the voltage depending on touch location. We use a pull-down resistor (10k between the wiper and ground) to keep the output at 0V when it's not being touched. This way you can get trigger information.

oh, perfect!
i was curious, because i didn't see the resistance mentioned anywhere on the website when I clicked 'more info'.

thanks for the info, and the quick response.

the smaller ones have 10k total resistance. largest ones are around 20k.
