 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

A curiosity .. These look really nifty - I gather they are used in sound mixer desks etc. Been trying hard to design one into a project but haven't got there yet  any thoughts ? |

If you want to sense position, RS232/UART capable digital calipers are available for a few dollars - single digits. So you could get a dozen of those for one of these . Unless the feel of a linear pot was needed - but then why motorize it? On that page, they propose a usecase of interfacing to hardware you cannot/dont want to modify - in that case, a digital caliper based solution would still be cheaper and better (precision). Feels like a solution looking for a problem. Looks cool though. |

The (video of a) mixer console I saw, showed all the sliders moving back to preset or stored settings. Definitely a pre LCD-and-cheap-micro design ! They are a bit lightweight. Good for a simple no-screen interface or haptic feedback maybe. (Guess who still hates touchscreens  )ed - the budget calipers report changes in movement not absolute values - and the rs-232 has to be monitored for each change - so it can get complex quickly. |

Also now used on some domestic appliances such as space heaters, stereos, or air conditioners, where you can either make an adjustment at the appliance, or use a hand held remote. There have been rotary versions of these around for quite a while. Another interesting component to play with, are the servos used in model radio control. these are now low cost enough to use for all kinds of applications, including moving a potentiometer. Some of these servos are quite fast acting and powerful. Cheers, Tony. |
