Hello folks, I just come up with an idea, maybe there is a sensor like this made already... I'm thinking of a tuchsensitive sensor. Not the on/off type or with only one resistor value. I'm thinking of a tuchsensor that can register how far the (...) (21 years ago, 22-Dec-03, to lugnet.robotics)

(...) The cheaper music synthesisers (and perhaps the expensive ones too) do this by having two simple switches - set to switch at different points in the key's travel. All they do is measure the time between the first switch triggering and the (...) (21 years ago, 22-Dec-03, to lugnet.robotics)

(...) The touch sensors that come in the RIS set already work as you describe, and are even about the size of a 2x3 brick. The touch sensor has a variable resistance that changes as more force is applied to the button. You just have to read the raw (...) (21 years ago, 22-Dec-03, to lugnet.robotics)

(...) Are you sure your multimeter is up to the task? I have measured numerous touch sensors (from 1.5, 2.0 and cybermaster), all of them have a high value when not pressed (open for RIS 1.5 and 2.0, 10 to 15KOhm for Cybermaster that have a (...) (21 years ago, 23-Dec-03, to lugnet.robotics)

Instead of pressing the touch sensor directly, you could use a lever to press it, thereby giving more precision. "Øyvind Steinnes" <phoenix@online.no> wrote in message news:HqCGJ5.Gz@lugnet.com...
