Question DIY IR remote volume control addon

I would like to build a remote volume control for my older (non home theatre)
receiver. The audio/vca/motorpot section is no problem for me, I just can't find info on
the IR receiver/decoder section. There are IR receivers available at Radio Shack
but info on how to interface and program them escapes me.

Goals:
1. To be able to be controlled by an inexpensive universal remote using the
"Audio" button on the remote. Ideally, it would mimic a known home theatre
receiver so that I could just program the remote by holding the "Audio"
button and entering a three digit code.

2. To power up in a sane mode. Volume at 10% or so, NOT 100% or mute.

3. LED bar graph for gain/attenuation indication.

4. To be an external unit connected to the receiver's eq/processor loop.
No problem here. I have elex fabrication facilities.

If I get it going, I'll post link to complete info.

Thanks in advance for any info,
Emory

Ask Weeder Technologies,
http://www.weedtech.com/
Terry Weeder has a simple solution, but I don't know if his project or products still selling.

look at Philips Semiconductor for SAA3009 or SAA3049 (RC5-Receiver)

If you need a schematic for using the SAA with a motor poti, send me your email-address.
best regards

Kay

I just designed a remote control receiver some months ago - have a look here: http://stiftsbogtrykkeriet.dk/~mcs/Remote/index.html

I've used Philips RC5 code, which should work with all universal remotes

If you use a motorpot it will power up in the (in)sane position you left it in :-)

Is that nescessary for a motorpot?

I am also working on a remote controlled "passive preamp" as well as a board with relay or chip attenuators, but that's not complete yet...

Aren't those Philips chips obsolete? Can you still get them?

But it only took me a couple of hours to make my own replacement chip using a microcontroller ;-)

hello Mikkel

>Aren't those Philips chips obsolete? Can you still get them?

This is correct, but I have four.

>But it only took me a couple of hours to make my own
>replacement chip using a microcontroller ;-)

This is also correct, but can Emory do it?

Best regards

Perhaps not, but I could make him a chip. And many others could as well.

Here's some great info:
Pre-programmed PIC. Reads Sony RC. Has 4 or 8 momentary and toggle outputs.
http://www.pics.com/~grieb/IR.htm

I'm in progress of getting parts together.
Using relay on a toggle output for mute.
Using motorpot on momemtary outputs for volume.

http://24.92.73.209/pix/irvolcont.pdf
Might change daily. (As might the IP :-( )
Yes, the LM18200 H-Bridge is overkill but
I have several ;^)

Why you don't make your own controller?

Bascom is free for 2kb (Basic-Compiler for AVR, use the AT90s2313)
