Parallel Port Relays & Lockout Coils
nostrebor:
Well, OK. Now we are up to at least 4 relays that I would find useful. Using lockout coils to prevent attempted credits during times when the frontend is present is pure genius! I mat have to get one of those PCBs after all.
JoyMonkey:
I've had a look at my coin door and I don't see any lockout coils. I'm not surprised since it's pretty new, but I want to make sure I understand how these things work correctly.
Here's a photo of both sides of my mechs (this is a CoinControls door/mech from 1997), then a close-up of a little brass thingy. When the brass thingy is in the 'up' position, coins stay in the upper part of the mech until someone pushes reject in. The small silvery part seems to be magnetic steel, so I would imagine that an electromagnet (i.e. lockout coil) would be able to hold this in the 'up' position and thus render the mechs 'disabled'.
Is this right?
Rocky:
Lockout coils don't manipulate any of the coin mech parts, but you have the right idea.

Here's what I'm thinking of doing. A magnet will hold the 'brassy thing' in the reject position, just before Mame runs the electro-magnet will power up and pull the 'brassy thing' down to the accept position.
Can I buy small electro-magnets like this anywhere?
Edit: Yep, I'm on crack if I think this is going to work.

btw, Hoagie... Your talking about a different product for a different purpose.
You want everything to turn on with one switch.
They want something to turn on the monitor AFTER they change the outgoing frequency to 15hz. IE after boot and after the initial config... and at the point of launching probably advancedmame / advancemenu ect.
I would love to see this hooked up to a control panel release solenoid. I looked into doing that at one point and realised I didn't know what to look at in solenoids to find one that would work... Let alone how to handle the computer -> electronics. I ended up scrapping the idea (especially since I had enought crap to work out...)... but one day I might look into it again.
