Custom Buttons - Custom Physical Plastic Buttons to controll CarPC via I/O

**tempgp** · 02-23-2009, 06:11 PM

Hey all I wasnt sure where to put it either into fabrication or to IO forum so I ended up here.

I have full carPC proto up and running im my car but stock radio is still woking as primary audio source, I dont want to remove stock radio caz it has physical buttons (not a touch screen) so i can actually controll it even whlile going 60mph (try to do that with touch screen and not to crush)

So I decided to do custom either micro pannel or 1 Din thingie that would have my buttons and it will look perfecly in my car or in any other car.

Now I have a modeler who can do the design of the button pannel, I also foumd casting guys that will do actuall molding of the buttons (yey any one want to have a gold buttons ;-) that gona be easy and real cool) Now the only problem non of us have any experiance doing actuall pannels. (Im really combining juverly business to a car business) So if some one has any tips, i'm listening.

In any even to start with something I wrote a small app to chack the proto posibbilitues.

bellow on pix you can see my APP controlling Pause / resume / play functionality of WinAmp with two phisical buttons. I can also pull out the song info and output it on the LCD (dot lcd) screen

Bottom line:
If you are interested in the project please let me know. If you have any ideas on fabrication this please let me know. If you one one button set for yourself please let me know (they will be expansive, but i still want them

Very nice!

Perhaps a mini tutorial on how you accomplished that?

**tempgp** · 02-24-2009, 11:24 PM

um tutorial ... thats possible.. I think posting my program would be much more useful ;-)

**keisuke** · 02-25-2009, 12:35 AM

**tempgp** · 02-25-2009, 11:43 AM

I love it, it is exactly what I was hoping to do.

If you get the chance, PM me with any info, or the code if you are willing to share. Set up tips, wiring diagrams, etc. would also be appreciated, since this aspect of PC integration is a little new to me.

Again, nice work!

Ok I will try to prepare detailed info

**tempgp** · 02-25-2009, 05:57 PM

In order to get Resume / Pause functionality you need to connect Switch (Button) to Imput connectrors 0 and G (Ground), for play button fubctionality connect button to 1 and G terminals
