I was planning to run MameHooker anyway, to drive the Q*Bert knocker - so I'll definitely consider this option. With this, it would be possible to have the relay (or opto-isolator) outside the gun, and just run power wiring from cabinet to gun to solenoid. This would save room inside the gun. Andy - thanks for the circuit diagram. I couldn't source parts locally, so now I'm waiting on Mouser. I'l be trying this option too. WindDrake - thanks for the pointer on PPTC's - knowing nothing about electronics, I've no idea how much I should be concerned about the source/gate shorting issue, but a~ $0.30 component for piece of mind seems quite reasonable. For mounting - I've been scratching my head. The solenoids I have need some room inside the gun housing, and there aren't many options. If I may link to Andy's site for illustrative purposes: There is a perfect spot to the left and slightly lower than that red button. However, the solenoid is pointing in the wrong direction, and the feel is all wrong when it fires. Along the top is an option, but the IR Receiver board and USB cable are an issue, and other internals get in the way. Anywhere in the lower ~2/3 doesn't have enough width (gun housing wont close properly). I'll figure something out sooner or later - I just hope I don't destroy too many things along the way. For this particular solenoid, the plunger is actually drawn in when it fires, striking the metal plate at the bottom (see pic way up at the top). My current plan is to use a spring to hold it out. It will likely need a stopper of sorts so it doesn't fly out all the way. I am also trying to think of some way to add weight to the exposed end for greater impact. There's also a metallic clicking sound on impact that I may attempt to dampen (small piece of rubber or something). Sorry I don't have more updates. However, the options from Andy and Howard are really great. I believe my original circuit should provide a general purpose solution. Andy's circuit is great for those with an aimtrack, and MameHooker sounds like another excellent general purpose solution. Thanks |

I haven't done this on a gun, but I have used solenoids before. I think as dampener you need something a bit softer than rubber. That strip insulation you get for doors and windows (the black foam stuff that sticks on with double-sided tape) works really well. A piece of rubber underneath that wouldn't hurt though. I've got the spare parts so you've inspired me to do this mod myself. I've already tested the "generic mode" I spoke of in the latest, unreleased version of mamehooker and it works really well. Of course I tested it on win 7... I'll have to throw it on one of my xp-based mame cabs to make sure it still works well there. |

Sorry hate to ask but does anyone know where to buy the 33n10 transistor in andy's diagram? google has been less than useful. Thanks so much!!! |
