DS Misc > DS infrared

#84557 - Mrshlee - Tue May 23, 2006 10:51 am

Hello,
I'm looking into a project.
Turning the DS into an infrared remote
for the TV/VCR/DVD/Robosapian ;)

Project : IRDA

Obviously the DS doesn't have a IR port.. Some of the older gameboys did but Im sure we can work around it

Possible ways to deal.
1. The famous IPOD IR
http://features.engadget.com/2004/07/27/how-to-turn-your-ipod-in-to-a-universal-infrared-remote-control/
[Images not permitted - Click here to view it]

2. Serial to IR
Avaliable from any good electronics store are generally standard 4port computer IR adapters *look on old motherboards for the 4port IR*

but HOW do you connect serial to the DS - The PassME has a serial port *possible but hard* need to write software for the PassME/drivers to manage the i/o - a pain

OR

Using something like this http://www.pjrc.com/tech/mp3/ircontroller/

Using the DSerial i/o - If the unit is ever released, you might be able to connect the IR to it. - If natrium42 codes the software support for i/o - All you need to do write the drivers for the i/o *easier*

OR

DSMem by amadeus

DSMem is an awesome little unit with DSLinux booting and serial i/o.. now this is the best option so far
DSLinux SHOULD have full support for all the DSMEM hardware
so the serial should be mounted at /dev/serial
using LIRC - Linux Infrared Remote Control
We could simple hook ANY old IRDA, Lirc should work for us with less effort/cheaper then the other options

Its obviously not as easy as that

Ofcourse the power drain would need to be looked at but I doubt the LEDS would take much more then.. 1.5volts when IN use

Any other options or opinions?

I've been looking for small low power 4 pin IRDA/IR serial with both RX/TX.. but that seems to be hard to find without a microcontroller *more power*

The easier option is having a reciever setup for devs - So you can record the signal
and the "general" ir sender.. so people can hook it up and simply use it :D

I have a decent electronics background but If anyone in the know could give there opinion on this..

amadeus or Nat42?

We can allways keep poking natrium42 for DSerial

As a developer, you wouldn't have to record, as the IR signals for remotes got a standard they follow. But if you got something that doesn't care about this standard, connect a IR Sensor to the mic-in and capture it.

Btw. how did you measure power consumption. Your initial post is a bit wrong about what the consumption is:
Quote:

The pure volts don't say anything on the power consumption. the Volt*Ampere (=Watts) is what you should care about. Easiest case btw, would be components which operates at 5.2V

Natrium42 tried that out once :P

id love to see data transfer via IR :) :)

that'd be great for transferring files from mobile phones :)

I tried doing this yesterday.
I found an old remote, hacked out the IR emitter, soldered it to a headphone jack, plugged it into the DS, checked it was working with a digital camera, desoldered it (i had soldered it backwards), resoldered it the right way around and then realised it was broken.
This is most likely because I fail at soldering and probably overheated the IR and cooked it.

However, I'm going to get some board, some IR emitters and try again.
Shouldn't be too hard....

(IR is kinda similar to audio. This is where i got the idea. I wanted to use a remote for a moonshell remote using the mic port and a moonshell plugin that compared what it receives through the mic port with the signals it had stored (for my remote)).

I was the first person to have this idea, and I think you need to connect a modulator to the audio out to make the IR signal to be modulated

Did I read somewhere that there is a register to disable the volume slider? If there is, you could use that, I don't think there is any other use for that.

so the general consensis is an Audio based IR mod would be the easiest at the moment.

Yes, because it's tried and tested (with the iPod and laptops and stuff).
Anyway, I should get some more IR emitters and a reciever in a few days and some stripboard.
I shall then try again.
That DS mic socket is gonna be a PITA.

prove it that you was the first person...



here is a prove that you're wrong ;)

I was earlier ;)
