I wondered about that. Are you sure? Even with one button pushed it should not give an input to the opposing controller. However the "ground" side will see voltage. The other option would be to use a double pole switch. one switch that operates two separate circuits.
Actually you might be right, but the deed is done lol
I was using an old turn key switch I found just because I thought turning off free-play using a key was cool, didn't go out for parts. I added the other switch so I can lock it up and quit getting my hi-scores erased.
So I've got my truck in my name and everything now, and I made some modifications to my radio.
www.allpar.com/stereo/1980/index.html I made an AUX input, works fine and everything. But when I plug my CD player in, I get this loud interference I think from the motor spinning the CD. Also everything going into the AUX is really loud, so I have to turn the volume on things like my phone down to 1. I'm wondering, is there some kind of capacitor that I need to throw in?
I wired it to the trace going to the cassette head to emulate the cassette-to-aux adapter I had before, but with a direct feed. (Which I stopped using because it never made good contact to the head) I opened the cassette to see if it had any capacitors or filters or anything and it didn't. The CD player worked before with the adapter so I'm not sure what's different... A diode to control the direction of the signal maybe?
