Searching Fader Knob
We are searching metallic fader knobs for a new mixing console design.
Do you know some knob manufacturer ? Thanks and regards Silvano |

Reasonably priced, and they will do custom shapes in small runs. They do most of the knobs on Collins avionics. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

We suppose to need metal knob because we need touch sensitive fader.
We haven't done experiment yet, but I suppose we need a conductive path between man finger and the chip that does touch sense. If you have some ideas, please let me know.

The system does automation value punch-in (start overwriting automation
value) when the technician touch the knob. It would be possible to compare the position of the knob with the previously recorded value; if they are different, this means that some external force (technician one's) is acting on the knob. Suppose that the fader is flying; I need to oppose its running with force; the system sense a difference between ideal and real position value and stop the motor force and enter writing automation value. But what about punch out ? How can I sense when the technician release the knob to punch-out and glide to previously recorded value ? Does somebody have technical experience with touch sense ?

They are plastic with a thin layer of chrome plating, but the plating should be conductive enough to work a capacitive touch sense device. --scott -- "C'est un Nagra.

Dale Manquen (http://www.manquen.net) handles them in the US and would be a good place to start if you can't find a distributor closer to you. He's mentioned that he carries some metal fader knobs. -- I'm really Mike Rivers ) However, until the spam goes away or Hell freezes over, lots of IP addresses are blocked from this system.

Regards Silvano I think touch sense is based on changing capacitance in some way when the knob is touched. To be honest, I can't remember. The MXR Pitch Transposer uses this to select between presets. Some of the old analog synths had touch keyboards. EMS and Buchla come to mind. Electronotes newsletter has some information on building touch keyboards... both mechanical and electrical aspects. I think "Getting Started in Electronics" book written by Forest Mims for Radio Shack might have a circuit for a touch activated lamp. Peter |

If you have some ideas, please let me know. You could use a metal plated plastic knob. I think there are some maufacturers doing this. In the UK the obvious suppliers are Re-An and Sifam. Graham |

A little bit - yes. I know the theory and have worked on touch sensitive faders but never had to design one from scratch. Graham |
