Infrared receiver/decoder

[Samuel]

Hello everyone,

I want to control (on/off) a number of small motors (three or four)
using an infrared signal, generated by a Nokia 3650 mobile phone. The
idea is that the signal from the mobile phone will contain the on/off
position of the motors. The receiver/decoder should correspondingly
transform the signal into on/off signals that are then used to switch
on/switch off the motors. Does anyone have an idea as to how this is
accomplished? And if it is even possible?

Any help will be greatly appreciated.

Kind regards,

Samuel

What sort of IR can the phone generate?

It is an interesting idea.
I wanted to make an universal IR remote for my TV and video in it.
Mine (other make) speaks Irda (can communicate with the PC).
So perhaps an Irda receiver will be suitable.
For many phones, especially Nokia, there are programs that
allow you to modify the flash memory, remove simlock, and also to
dump the code I think.
Now all you need is the model of processor, and write your own code.
But of CAUSE I have not tried, would not want a Nokia anyways,
sets your pants on fire.
Google 'unlock nokia'.
Maybe a start.
Phones are getting better, mine has camera, internet, email, organizer,
and is NOT made in the US.
The camera can see better in the dark then I can!

Hello Ian,

I'm not quite sure what you mean, but the tech spec docs say that the
phone complies with the IrDA-standard.

Ok, more accurately.
What sort of software on the phone will you be doing this with?

I have the Linux source of a --specific other manufacturer-- for the PC
communication part, they have put it in the open source.
If you emulate that other (PC side) part of irda (plenty of diagrams around),
and pretend to be a PC, you could work without a software change.
I have tried to compile the stuff, biut some xx.irda.xx structure seems to be
different in the 2.4.20 kernel I use.
If one is seriously interested I can give a reference where to find that source.
Cannot promise it will work with Nokia though.
In any case it is GPL, and you will have to respect that.
You could also monitor protocol with a simple IR detector, and log it.
More work perhaps...
Then use some sequences...

Hello Ian,

I'll be using the Java 2 Micro Edition. The phone has a built-in Java interpreter.
