Musical Keyboard foot pedal to Gas Pedal conversion?
(1/3) > >>
DeLuSioNal29:
Hello everyone!

I was toying with the idea of inserting a 5" mini steering wheel on my control panel using the spinner knob design.

Then I got this cool idea of how to make a gas pedal for my arcade to go with it. :-\
I wanted the following features:

A)  Relatively cheap
B)  Easy to modify to make it a "button"
C)  Easy to take out and tuck back away when not in use

The musical keyboard pedal I wanted to modify would be here:

It's only $12.99 with free shipping.  My thought would be to modify the innards of the pedal to simply have an "open/closed circuit" setup.  Then I can have it connect to the player 1 button on the I-pac.  i.e. - if you press on the pedal it would close the circuit and "turn on" the player 1 button;  when you let go, it would stop.  I'm not looking for analog control, just a simple way of depressing the button with your foot instead of your hand. :applaud:

Nice and simple.  Any thoughts?

I think that pedal is probably already "digital"  It does look like it has any travel to it to be analog.  Probably be a simple matter of just wiring it right up.

That pedal is a switch, but I think it is wired normally closed, it seems like some keyboards work with normally open and some work with normally closed.  There are pedals that are normally open and they would work really simple with your idea.  Either add a 1/4 tip-sleeve jack to the cabinet, or hook one of the wires for the pedal to the ground and one to the control line, just like a button switch.

Here is a switchable one that allows it to be either NO or NC.

Hey.  I did just that 3 years ago when I added wheels to my cabinet.  I never got around to setting up a proper website, but you can see some pictures here:

The foot pedal is just wired to the Player 1 button 1....and the same goes for the second pedal (P2 B1).  It works fine.  It feels better than pressing a button to accelerate.

Almost positive that this pedal does exactly that already. (on/off)

So the only thing to change for your application would be to install a phono jack in the cab so that you could plug/unplug it. (since you mentioned moving it out of the way)
Or you could just hack the phono plug off and hardwire it as well.
