Re: Remote controlled audio potentiometer (OT?) |

Are you absolutely sure the volume control on your amplifier is a
potentiometer? Many new amps use an encoder (noiseless), which
essentially uses pulses, which would make an IR remote project
somewhat easier.
Either way, the project will not be simple.
The money & hours spent on designing & machining an IR servo might be
better off spent on an amp that comes with a remote.
Here's an example project for a realtively simple speaker switch to
see what you're getting into;

Google for "IR remote projects"
G'Luck!

I would like to change the manual volume potentiometer of my integrated
amplifier with a motor-driven potentiometer which must be infrared
controlled.
My question is simple...
How do I do that?
I've already chosen the potentiometer, what do I need now? A servo control?
And what about the infrared control and reciever?
Do you have any idea about some newsgroup I colud ask in?
Thank You |
