| How hot do your solenoids get? With Video |

A question for anyone with gun recoil solenoids fitted, how hot do yours get? The reason I ask is because I have made a recoil circuit to take the signals from mamehooker and activate the solenoids. they are the standard solenoids from ultimarc with my circuit and a 24v 5amp psu. I started setting the guns up with the various emulators the other day but after about ten minutes of playing T2 and operation wolf withe the automatic recoils I noticed that the gun shell was quite hot, not burning hot but hotter than warm if you know what i mean ??? Do your guns get warmand should i be worried? Im no electronics expert but my circuit does at least work but if anyone would like to take a look and advise some changes i could make then I would be hugely greatful. Its over in the automated projects section. Please help me! :notworthy: |

No one? :dunno |

Relatively few people are using solenoids and of those who are, I'd guess that nearly all of them are using the Aim-Trak firmware to trigger them instead of MAMEhooker. So their solenoids aren't getting the workout yours are. The feedback on the positional gun that I use is a vibration motor hooked up to the trigger, so it isn't comparable. |

Cheers for replying, I know a lot of people will be using stock firmware but, if they could stand there repeatedly pulling the trigger as fast as they can for ten minutes and then check the temperature they would be doing some great research :lol Seriously though, I was hoping some people out their would have recoil guns and would have noticed whether they got hot. |

What's the resistance across the coil? 5 Amps/24v means they are using something like a 6ohm coil. This means you are dumping something like 100-120 watts of power dissipated every time you hit the trigger. If MAME Hooker is keeping the drive to the transistor held down too long, you are going to dump power into the coil without generating any effect, and bleeding that power off as heat. I'd try shedding some drive time, maybe cut a third of it out and go from there. |
