New IR Control Desing
2 Attachment(s)
I'm starting to work on my new IR remote control for preamp.
I red a lot of posts on this site but was never satisfy with the different approach. I knew the Basic Stamp and like the way I can easily change and experiment with it.

My first protype of IR receiver/decoder is working. :cool:
The IR receiver and decoder is based on the work of Michael Owings. See is excellent work at:

The receiver is using an PIC12C508 MCU and a Sharp IS1U621L IR receiver. All parts can be obtained easily from Digikey. It accepts any Sony remote.

The control will be done using a BasicStamp2. The preamp display will be a BasicStamp serial compatible LCD.
A led is also included that flash with the IR received.
I'm using a BasicStamp2 kit to read the code at the moment.

This kit will be used in my next Classe Clone Preamp and my future XBOSOZ Preamp.

Schematic, Bill of material and code will follow...

Picture of the prototype:

So is it working. ? what is it's functions so far..?

Congratulations with your new decoder !

Since you mention preamps as the host for your IR remote project you are invited to have a look at (in case you haven't already). Its a decoder project that initially started as a means to build a remote controlled standard analog preamp. I have no idea if this is something you might find interesting or not :-)

:att'n: Warning - this is a slick piece of self-promotion !! :att'n:

Great site
Thanks. A lot of interesting links. However the source code is not there. My version will offer full programmibilty using the Stamp and I will share all my code. :clown:

Thanks again.

So how did this project turn out?

More 'self promotion'. Hit www below if you want code for a pic for decoding RC5.

The code is a bit unusual, it is a statemachine written in sw.
Not my idea btw.

Actual Prototype
2 Attachment(s)
Here my actual prototype of a motorized volume control preamp version. It used the Sony PIC predecoding IC for the IR remote codes. The preamp includes some nice features for now:
Features supported:
-Motorized Volume Pot. control with Min & Max course position detection (optional)
-Source, Mute and Stanby functions
-5 Relays source control
-Mute and Standby Functions
-Relays drivers IC and PCF8574 port expander I2C bus (for additional relays control)
-Mute actived during Source change to reduce switching noise.
-ESD buttons protection (like the APOX)

The actual prototype is not fully functionnal yet. Debugged functions are:
-Manuals (buttons) functions
-I2C functions OK

The remote control integration is not completed yet.

Take note that this schematic is the control section only. You need to integrate that to your preamp desing.

Feel free to work on this desing and keep me posted.

This is the actual Basic Stamp code, version 0.5, still not fully functionnal.

if anyone is interested, i have code for the RC5 Philips is in C for PIC16F877, but you can change it for any was originally for a real time clock that you could change the time with a universal remote control..feel free to email me if you would like the code

what about a schematic for the relay's ?
