Hi
I am trying to use copper tape
With the bare conductive touchboard and with a cable run of about 7 meters.
The cable is this one
And it doesn't work.
The longest I have managed to have the cable running at is about 2 meters after that the readings are not very reliable.
Can anyone suggest how I can increase this cable to 7 meters?
Thanks
Seb

Not knowing what you are sending over the cable exactly, I assume you need gain which can be obtained with the use of an op-amp in the the sending side.
Is the wire being used for touch sensing? If so, I'm surprised you get 2 meters to work! Touch sensing is particularly fiddly, because it's a very weak signal - you don't have to pick up much noise to make it stop working.
spycatcher2k - this was my backup plan but wanted to check if there was something else I could do
DrAzzy - yes I am using touch sensing.
Yeah, cable runs for touch sensinf (between sensor board and sensing element, ie, the thing you touch) should be kept as short as practical.
