Remote Control?

ShinOBIWAN · 17th December 2005, 11:26 AM

Hi all,

One thing I've never seen or heard anyone do in DIYAudio is a remote control for the volume. I've seen plenty of attenuators with motors but what about the IC logic controllers and IR sensors for the remote control?

I would greatly appreciate any links or info folks have on this subject.

You would need:

An IR reciever to pick up 35KHz RC5/whatever IR signals
A Microcontroller (pretty much unavoidable)
For driving a motor, a H-bridge IC or discrete H-bridge.

The second part is the stumbling block for most users, but there's really no practical way around it.

Rod Elliot saves the day though as he has a remote control project: http://sound.westhost.com/project110.htm still involving a PIC microcontroller but you can get these pre-programmed from him.

Holtek make a range of pre-programmed IC's for remote control, and they are cheaper than buying PIC's.

That's OK if you're happy making your own remote handset. If you want to use standard remote controls though, they all speak RC5 or such, so you pretty much need a microcontroller.

The Philips RC5 is only one of MANY completely different remote control systems, although it is the singular most popular one - presumably because Philips are a major component supplier to other manufacturers?.

Not to forget the NEC format too,which is quite popular in Asia.

Anyone has tried the http://www.diycable.com/main/product...roducts_id=505
kit?

I am thinking of ordering it but I would appreciate some comments if possible.

Hi Ant, what did you end up with?

Hi Vikash

As of yet nothing but I found out the eaiest method, for me, would be a Dact stepped attenuator (8-way variety) with the Bent Audio remote kit for the Dact.

Here's the attenuator:

And the remote:

Also take a look at an exact same configuration that Ed built (its under 'Volume Control' on this page):
