  • Computer as the remote??

    Heres a question. Most people put an IR reciever on the PC and use a remote to send a signal. What If I wanted the PC to send the signal to my headunit? That way I can use PC controls to change inputs, control my radio ect, instead of using a separate remote.

    Basically use a program to scan a signal, and assign it to a button to control the radio. Like source, mute, ect.

    Ideas? Comments?

    you need an ir emitter, there are several ready made ones, lemme see what I can dig up

      this seems to be a solution, BUT I dunno how I would integrate that into an application.

        i was gonna use this to control my headunit with the backseat controls of my explorer it could probably be modded to work with a serial port or some relays

              Im sure it is possible, like the others said, you can ether buy a unit to send and recive IR signals, or you could build one. Like you said you can train grider to recive a signal from your remote that came with the HU and duplicate that signal for transmitting back to the head unit. havent really messed around with it yet but im sure it can be done

                  Erazor, I built one of the original serial UIRT's a few years ago and have had it working very well as a reciever since but have never got round to testing the emitters as i just use the all-in-one remote i use for my PC to do everything.

                  There is a newer version than mine but i didnt keep up with the design as mine hs worked fine. Will dig up some info when i get home from work if the info is no longer on the internet (don't think the UIRT link above has info for DIY)

                    Just thinking after seeign a link off the page posted by -B-e-n- (http://winlirc.sourceforge.net/controlbywire.html) that maybe you could simply miss out the IR emitters and remove the reciever from your device and wire direct up to save having to loacte an IR transmitter anywhere.

                    Or it might be better to remotly mount your device reciver in a box with your emitters pointing direct at it. might make it more reliable - especially in sunlight.

                    Other way would be to use a relay board and hook it directly to the tactile switches in your stereo - not really a hard job if you have a nice small soldering iron.

                        What became of this erazor?
                        How did you get software to send the signals? I'm looking at WinLIRC, but the infrared.ocx doesn't support sending data. I fear I may have to do everything manually (ie: interfacing with the serial port directly), but am not quite sure where to start...

                          Any thoughts about using an IR-BLASTER, such as the one that comes with the WindowsMCE remote? Certain buttons (like channel) send a signal to specified IR-blaster without even going through the computer. Im sure you could configure (with software) hotkeys that could send signals to the IR-blaster, however you would have to be willing to have this little box over the IR receiver of your HU

                            Thanks for the idea Fiskarz, but I think it would be more work finding an IR Blaster which: speaks the same protocol as my HU, and has an API.

                            After hours and hours of searching, I found this link which will solve all of our problems (more or less). http://www.promixis.com/phpBB2/viewt...ir+transmitter

                              well, if there was a way to capture the signals that the remote from your headunit puts out, you could jus copy those and put them to the emitter, could you not?

                              I'm thinking of getting a good multifunction remote offa ebay, and capturing all the IR codes as i press the buttons on it, then reuse then have a sub in my VB project that monitors the buffer on the serial port, when it sees something there, reads the code that it got from the remote and does what i program it to....
