A twisted tale about a logarithmic relay attenuator

Jason, The controller we supply is very similar to the kookaburra. It uses a volume pot which is ready by an ADC on a microntroller which does the actual switching. The pot is not in the signal path. So it works exactly like an ordinary volume pot or rotary stepped attenuator.

Cheers!

I already know that.! What i'm asking is , s this device a faster one or slower one. can the relays keep up with the turning of the knob ?

Well, it works pretty much as fast as you can turn the knob. 😉 There is no rotary encoder which your post mentioned. Thats why I explained how it works.


SWEET! thank's Russ. The one i have nos is annoying and slow Sounds good but when you need to turn down the stereo because of a phone or something it takes to long its faster to press pause on the cd-player..

Is your relay based volume pot workable with 12V

4" x 1.5" Allow for about 4.5" x 1.75" or so for PCB + connectors dependant on how you decide to wire it. A stuffed relay PCB is about .625" tall without standoffs. The conttroller is about 1.125" tall without standoffs.

Are both relay PCB and controller boards have the same size?
Thanks
 
Single side layout for G6H

Ok Craig, and a few others.

I have completed a layout for the Joshua Tree with G6H relays instead of G6K. The G6H relays are larger so the board is a bit larger at 5.6" x 2".But it is full featured.

Its actually a much better layout than he first one I posted.

What do you guys think?

Super Now i shal order one and a input Selector. 🙂
 
OK. I have no problem buying the controller board and PIC from Twisted Pear and building a hybrid set up. Have you looked at the new layout to see if it is possible to locate mounting holes so that your current controller will stack on it?

You are doing such fabulous work, I hate to ask for more details. I owe you a few brews if you are ever in the Valley. Should hit 100 this week, so beer time is definitely upon us.
