harpz Posted October 12, 2010 Report Share Posted October 12, 2010 (edited) hello : ) I wonder if anyone can help? I have been trying to figure a way to create a touch sense circuit for a motor fader. I tried a transistor capacitance type circuit and it worked well with a small wire connected to base, but when I connected it to the touch fader connection the circuit would not turn off , even if i stood back away from the fader. i cannot find a qt100 IC (touch sense ic). or any IC that i can solder to my vero board ( or test in my breadboard) I am so lost on what to do , i wonder what you guys do to cut the motor faders power when you touch the fader? thanks for any help or pointers. harpz : P ( edit= I am using an alps fader) Edited October 12, 2010 by harpz Quote Link to comment Share on other sites More sharing options...

harpz Posted October 13, 2010 Author Report Share Posted October 13, 2010 hi, thanks for your reply. I forgot to mention, I have made my own servo type circuit/software(using max msp) to control the fader. it works o.k, but I was looking for a little touch sense schematic that I might be able to incorporate into my design. perhaps the touch sense circuit would output a logic 5v so that I could trigger a relay to turn off the motors power. I haven't used the midibox as of yet, is the DINXx part of this? sorry if that's a daft question. : P thanks : ) Quote Link to comment Share on other sites More sharing options...
atmel_fan Posted November 14, 2010 Report Share Posted November 14, 2010 (edited) Hi, try use this schemat based on TASCAM FW-1884. I tested and this work ok... Edited November 14, 2010 by atmel_fan Quote Link to comment Share on other sites More sharing options...
