USB IR Toy

Hi I,m a newbie to this site. I was wondering if someone could kindly help me. I help people with disabilties and I am trying to help aparticular person whereby he would like to activate his stereo using his capability switch. I have come up with an Idea since his stereo has an infra red receiver and we only require two codes from the remote i.e skip button function and play button function for the cd. I was wondering would the USB IR Toy store both codes. Please can someone help us as you will be putting a smile on face of a child with disability.

What's the brand and model of the stereo?

Checking the manufacturer's website can reveal what type of IR protocol the stereo uses.

The IR Toy is an IR receiver / transmitter, so it could theoretically be used with any remote control, and then have it send the proper codes to the stereo, but it complicates things as you also need a PC to accomplish this.

So the easiest way would be to determine what IR signal the stereo requires and start from there.

EDIT: Some time ago, I suggested a "stored codes" feature to allow the sending of specific codes without the intervention of PC software. If it is implemented in the firmware you could theoretically set: Signal A == (triggers) ==> Code B.

Dear Liyin

I am a bit confused as i already have the original remote control.

What I would like to do is to put two different codes into a device in this case if possible into the  IR toy. Once this is achieved the next bit is easy i will adapt so that the child with the disability uses a big switch and the idea is  when he hits the switch it will transmit the play code when he hits the other switch it will skip tracks.

If the IR Toy is connected to a PC then you can do it via software application, if not then you need to modify the IR Toy's firmware.

Have you thought of making a prop that includes the remote's circuit board, you can link the switches to the respective remote button contact.

sony rc uses carbon contacts thus long lead from the switch changes resistance and output code. But if your saying the usb ir toy can store and transmit two different codes then it should work,please advise.

No, IR Toy can't currently do that.

You can connect a momentary switch to the desired contact (Play or Skip button contact) as a replacement for the conductive material in the bottom end of the rubber button.

When the switch is press / pushed / pull and its two poles connected, it will do the same thing as if the rubber button was push against the PCB contact.

[quote author="united786"]sony rc uses carbon contacts thus long lead from the switch changes resistance and output code.[/quote]The carbon contacts should be non-resistive.  They should be in a scanned matrix, such that a momentary, normally open (NO) switch would work.  I am not aware of any design which uses a different resistance for each button contact, because that would likely make the buttons more expensive to manufacture.

maybe off topic but I would buy used remote from ebay and soldered external big buttons to actual remote buttons....


EDIT... I guess I was slow with solution
