  • Custom IR (or RF) transmitter

    I'd like an IR transmitter on my steering wheel to control my computer. I created a receiver based on a LIRC design, but I'm having trouble finding a suitable remote to use. (The pioneer cd-sr100 doesn't have enough buttons - I'd like > 12).

    I've done alot of searching and all examples I've found look quite complex. Not to mention that they require a PC or other programmable device (PIC) which I don't have the foggiest clue about...

    The resulting device would need to follow the curve of my steering wheel. One route I'm thinking about is to take the most basic remote I can find and reconstruct it out of new parts, salvaging the processor. But, I need to find such a remote.

    Does anyone have any suggestions?

    Has no one on this board ever created/modded a remote control?
    I find that hard to believe. Does anyone know of a ready-made PIC capable of making an IR pulse so that it's compatible with LIRC? Or, does anyone know of a good, simple, 12+ key remote control I could hack apart?

      Best way i found to get decent codes was to use a programable remote (jsut got some ordinary thing with loads of buttons as it is for my home PC) and then go throught he code book trying different manufactures codes. They i watched the code in girder to see if the signal being sent was picked up by my reciever (UIRT) and if it was a nice simple signal not a mixture as you get with some. Basically i just used trial and error until i had enough to fill all the devices on my remote - ed DVD button for films, TV for general windows control etc etc.

      I would suggest you just go look for a replacement programable remote that can be used with all manufacturers and hack it aprt for your needs. The little mad-catz ps2 remote is pretty cool and small and has 2 sides with lots of buttons.

        IR Transmitters are sometimes called "IR Blasters" and if you search google for this there's quite a few stores that sell them. I remember that MythTV supports some types of IR Blaster, if you wanted to look through source code on how to talk to them.

        Otherwise, some remote controls (like a Packard Bell PC one that i have) have a lot of buttons (20+), and are a single chip wired up to a big button grid, and as far as i know they're standard buttons, not capacitance ones. You could just buy one of those, saw up the PCB and solder your own connections in.
