Quantum Touch Slider (linear position sensor)


Recommended Posts

Looks pretty interesting - $3.51 at digikey. From the picture it appears that the touch pad is split into 18 different zones - is that high enough resolution for a mixer? Regardless it looks like a nice add-on to the midibox platform.

The documentation says that it has a resolution of 128 (I think it can generate that by comparing changes in capacitence in the adjacent... Ummm.. electrodes).  128 isn't great, though just as good as 99% of the midi-able sliders out there, but I don't see why you couldn't have (for example) 2 units stacked lengthwise to create 256 positions and resolve the value in software....  Unless the sensors will interact with each other badly..

Just some thoughts...

Ok, I guess this is an old thread that was sort of left on a cliffhanger...

Stryd:

  Yeah, it's just the IC, but if I remember right it requires very few external components to drive it, and the slide surface is one that you specify, and of course, you'll have to etch PCBs for the electrodes...
