Several products with encoders I've seen does > that . It rotates endlessly. The way these rotary encoders work is that they create a two-bit "Gray code" that allows you to determine the direction of the rotation, the rest needs to be done in software. But without the "double volume step" I used you'd have to rotate a lot to get a meaningful change in volume which is annoying. If you want to change the volume you want it to change within one action to whatever you want it to be, you don't want to keep rotating it.
But of course this depends on your setup. If you have a very sensitive amp in a device with very high power output you can always change the command line parameter in the software to only use one edge, then you get single-step accuracy. mherger wrote: > Nice job!

I think somebody even claimed it was the single most > expensive part Logitech had ever used up to that day :-). Well, that thing is of course a different story with the force-feedback and all. But just a simple rotary encoder with decent haptics and, say, 50 Steps per rotation (150 would be perfect but I understand that's harder) is expensive. I found a nice one but it created that effect by using a reduction gear. That thing cost 30$ or so and also was way too big for the radio. What I didn't find in time but what I'm probably going to try for the next project is something like this: https://www.conrad.de/de/encoder-schaltpositionen-64-bourns-em14a0d-c24-l064n-1-st-447181.html 30$, 64 ticks per rotation and two button modes (normal and high-power) so that I can use play/pause and power on the same button. At this price it would only have been the second-most-expensive "component" because I paid $40 for the Tivoli Speaker (a new one!). But it would still top the huge battery at $30. But that thing with the aluminum knob I still have will probably be the controller of choice for my next project: a Transporter replacement with balanced (XLR) output, a second, (independently controllable) output channel for a subwoofer, one or two analog inputs (one with RIA preamp) and a small probably still passive display... Biggest challenge for that: find a good housing.... --- learn more about iPeng, the iPhone and iPad remote for the Squeezebox and Logitech UE Smart Radio as well as iPeng Party, the free Party-App, at penguinlovesmusic.com *New: iPeng 9, the Universal App for iPhone, iPad and Apple Watch* ------------------------------------------------------------------------ pippin's Profile: http://forums.slimdevices.com/member.php?userid=13777 View this thread: http://forums.slimdevices.com/showthread.php?t=107031 _______________________________________________ diy mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/diy
