Q-bert controls software asjustment ?

Level 42,  I just pmed you, thank you so much again.  This is going to be awesome.

You are right about the sound on that video clip.  I believe it is a sample and I don't think there is a knocker in that cab.  However, what's important is the lighting effect.  You can see the lights on the buttons flash when Q*bert jumps off and the knocker is supposed to fire.  In theory, when you plug the knocker into the ledWiz,  PowerMame and the LEDwiz won't distinguish the knocker from any other led, so it fires the knocker thinking it's an led.

Do you think there is any danger of power feeding back in  Sir Poonga's diagram.  I don't know much about that stuff and have never used a relay before.

Also, with the knocker, do you know if we will have to build a box for it?  Or does the knocker just hit itself?

Thanks again man

Kevin

Thenasty:
judging by the pic above, you will see that the 3 holes is for screwing the unit into (anywhere) inside the cab, and the the relay on the unit hit the metal piece. Thats all you need to do, just find a spot and screw the unit in. Some think that somehow where triggered, it hits the CABINET WOOD part, but the way that pic looks, it just hits the unit itself.
I aslo is thinking of adding a knocker inside that cab, but ATM, busy with other things...

Yeah, but what happens when it triggers the LED's on other moments, in other games ? You need ONE LED output dedicated for the knocker only. It doesn't matter if it's the LEDwiz or the I-pac/J-pac. It's simply a matter of putting out +5 Volts at the right moment, for the right time.
Even so: What you see happening to the LED's on the panel when Q*bert dies, is that the LED's increase and decrease in intensity (reasonably fast, but still). You don't want this. We don't need an analogue signal, we want a direct full 5 Volts.

So, I wonder if this can actualy be done with the Ledwizz and powermame. You at least need to reserve one led output for only the knocker, and that light may not be triggered in any other game (except for Pinballs maybe). I also believe that timing is essential. It has to go at exactly the right moment to get the real "feel".

No there's no danger because the relay is the protecting part here. It seperates the knocker circuit from the LEDwizz or I-pac/J-pac circuit. I still don't want to use a relay though...

It does hit itself, but the shock (noise) is transfered from the metal bracket into the wood panel you mount it on. I bet there is almost no sound when you would trigger the knocker while it is not mounted. It

Yeah, I haven't played around with powermame a ton, but from what I understand you dedicate one led port on the ledwiz to the knocker and you set it up so the qbert effect in powermame only triggers that one port.  In the example, he only had his buttons light up, not his led joysticks.  I also saw the fade effect on the buttons and will have to play around so that doesn't happen.  I think that is an effect you add on top of the initial triggering of the led.

However, since I haven't actually built it yet I certainly can't verify what I'm talking about.   I will have do it first and report back.  If it doesn't work, I have a i-pac and can qmame it if necessary.

Cheers level

It would be cool if it could be done with Powermame, since I prefer to use one version of mame. However, it looks like Powermame's development is coming to a halt...(see the Powermame section). which is a shame really.

My knocker is on it's way crossing the big water :)

Hey Kevin, maybe we should also get one of these:
