    DIY steering wheel remote for cars that dosent have.

    So, my car is pretty old, and there was no ption of passing cables for Steering wheel remote... So heres what i did. I think is pretty easy to be done from everyone without any much specific experiences!
    Normaly, since your car wont propably have airbag in the wheel, you will have plenty of space to work behind the mask of the wheel.
    So, i took a usb wirless remote for the pc, and i stripped its board. as you can see the keys, are normal circuits that close when you press the normal keys. so using some Solder, i glued, cables in those circuits. (This is the only really hard part, since the job is a liitle ditailed, but since i pulled it ovwer, i think everyone can. )
    this is how it looked like:

    Then , drill some holes , in the mask, add the buttons of your like, fill the holes with some putty (in my case it was polyster putty), and you are done! i used as keys the numpad numbers, so with macros and hotkeys, they can do almost anything!

    Great idea but don't settle for that - do a little (ok, a lot) more sanding. Do it without the buttons installed. I would go ahead and do the entire face, not just the corners.

    Next step - wireless battery charging, else using the horn circuit to charge them.

    battery isint a problem, since it lasts at least 2 years, and when it gets over, the mask is way to easy to remove and put new! i was thinking the horn harness, to give power to LEDS, but i couldn't find a way to do it without the horn shouting all the time (Any ideas on that would be welcome )
    Ye... about the sanding, i didint really knew if it was enough or not, only after the painting... so now i dont know if i can sand over the paint!!

    Say what? In the USA, airbags are required in all passenger vehicles produced after 1 April 1989 (light trucks added in 1997). Unless you bought an aftermarket steering wheel or your airbag has already been deployed, nearly everyone in the States has a driver's airbag.

    Very good concept, though, for those that are not using a steering wheel airbag. Personally I'd push it to the point of nearly looking like an F1 wheel. Like this:

    There are ways to send power and signals - depending on mods.

    The horn buttons typically short the ring to ground (the grounded steering shaft).
    The ring then grounds the horn relay coil whose other end is IGN +12V.
    Usually the relay takes a few hundred mA to energise (usually ~6-8V).

    If power is low, then power can be fed through the relays coil - maybe up to 100mA?


    But other methods include sending whatever you like to the horn ring - like AC signals on DC etc - but these are high impedance (resistance) signals or DC so as not to trigger the relay. (The horn button is a low impedance "short".)
    Signalling is usually fine since it's low power stuff.

    It's been ages since I looked at stuff like that, but I reckon a web search should find something, maybe multiplexed or AC signalling on horn circuits?

    Sorry, I'm tired and about to leave on a 10 hour drive.
    I'll be back in a few days.

    Oh, Settra, I didn't notice it was you who posted. Being from Greece, you have different regulations there. My apologies if I came across as rude.

    In your situation, though, with a wheel like that, I would definitely have a ton of fun with it. The shape and lack of airbag make for LOTS of fun options. A full keyboard, a gaming board (with programmable macro keys), a trackball and mouse buttons... You could even put a screen* on that. Possibilities are endless.


    *if you do put a screen on your steering wheel, make sure to use a clear covering, such as acrylic or lexan to prevent shattered glass from flying into your face if you are in an accident

    Why not use a wireless remote?
