Question about a joystick sending more than one signal when pressed

Ok, here was the problem:



Thats a bit blurry, but you can see the problem if you look.  The wire had come loose to the 'NO' connection and was touching both 'NO' and 'NC,'  so the circuit would stay closed when the switch was activated the first time.  I just resoldered it nice and tight to NO and it works fine.

One thing I noticed is that this guy soldered the ground wire to the NO, so this was actually the ground wire causing this problem.  He's got all the switches soldered that way with ground to the Open prong and the actual control wire connected to the ground.  I guess the switch doesn't care as long as its wired somehow to the Open prong and is grounded?

Yes, that bare wire looks like it's touching both so that would cause the problem.  Is it a bare wire in there?  I can't tell.  From what you've said so far, it would probably help you to re-wire the entire CP the proper way.  It may seem like a pain, but it will avoid more problems down the road and you'll learn the right way to do things. 

Nice glob of solder in the base of that joystick.  Nothing like soldering in tight quarters   :dizzy:

To upload a photo, you hit the "additional options..." link that you see on the bottom left of the text box. 

Glad you found the problem.   :cheers:

Nice that you got it working!

So I assume you tell guests that you bought the cab rather than building it?  I know my wife wouldn't let that in "her" house, but then I probably wouldn't let it in mine either.  Maybe you could take the components out and build your own down the road?

Mehhhh, at least it's fun and done!   :cheers:

I play tested for a while - it works.  I'm tempted to rewire, but I should probably play with the thing and get some enjoyment/value out of it first before I go messing with it

FYI - There is a door that goes on the bottom that I just haven't added.  I'm open to suggestions on how to add glass/bezel . . .

Since you commented on the look, I'll provide a bit about myself

I am not in any way a perfectionist. I don't really see problems, I work around them.

I am of the opinion that MAME cabinets are waaaaaay too expensive in terms of both time and money.  The kits without any controls or computer in them might be worth it, but the pre-assembled models are crazy.  I'm not saying that there isn't quality work that goes into them, but the amount of enjoyment I'm going to get out of MAME has a price and every option that I found out there was about 8x more than I wanted to spend in either time or money.

Before I found this, I was looking at hotel computer stands to just get something where I could stand up and play, and those were pretty ridiculous in pricing as well.  I don't mind sharing that this guy put this thing up for $300 including everything, and my thought was that the wiring in the controls was probably worth $300 just so I wouldn't have to do it.  For both myself and my wife the cost was way more important than the appearance.

I don't think I could name more than 5 people that I know who would even know what MAME is, or understand what it would take to even put something like this together.  If someone comes over and sees this they will either A) Want to play Galaga or B) Think video games are stupid.  If they think its ugly then good for them, but they will still probably want to play Galaga.

I just re-read the above and it sounds really defensive.  I should say that I am super jealous of the excellent cabs on this site and I wish I could have something that looks better - its just unattainable to me and I'm willing to settle for less.  If anyone wants to sell me a finished MAME machine for $300 then I will consider it seriously.

Just in case someone reads this thread and thinks - wow if that mess works then I'll just throw something together however and it'll be fine . . .

Please do not wire a control panel like the one in my pictures!  You'll be constantly troubleshooting little issues here or there with joysticks sticking etc.  It kinda sucks.  Plan your panel and run wires carefull to each section, securing them in place etc.
