Controls Doing Funny Things With Starter Solenoid Installed. Why?

(1/4) > >>

spacegoogie:
So I got my starter solenoids installed for my Visual PinBall.  http://www.hyperspin-fe.com/forum/showthread.php?t=7572&page=3
I use " [ " for left flipper and " C "  for right flipper. The funny thing is when the flippers are pressed fast and randomly (I'm testing this in notepad) I get other key presses.
Like so [c[c[c[c[c5[c[c[c[c56c[c[c[cjf5[c[c[c[c[c[ Why is key "5", "6", "J", "F", show it's being pressed when I'm only pressing the " [ " and "C" keys?
It's a problem because it's giving me error messages in visual pinball when these keys are pressed. Can someone help me try to figure out what the heck is going on?
I did some videos of the solenoids working a few days ago: http://www.youtube.com/user/spacegoogie#p/u/2/9CltVhj74Nw
Thanks!  :cheers:

Do you even have "5", "6", "J", "F" mapped on your encoder?  Try disconnecting the buttons leading to those and then try.  I wonder if when the solenoid is firing it's possibly causing rattling and making those others trigger.

Dazz,
these buttons are being used. I can not for the life of me figure out how this is possible.  :cheers:
Come to think of it Dazz, that could be the only thing that could be going on right is it's causing rattling. I mean how else could it happen? I'm going to disconnect those buttons and see what happens when I do it. Be back in a few.

Ond:
I suspect you're getting induced EMF when the solenoid moves back after release which on rapid button press is sending a charge back through your encoder.  That's off the top of my head.  You might need some sort of filter to prevent back EMF registering 'ghost' button presses.

CRAP!! :banghead: I disconnected  the wires from the switch's and the keys were still popN up?  :dunno
