    Default 120 VAC Blink?

    I'm coming along nicely on my MIB...

    Crate. Check.
    Pneumatics. Check.

    I'm wiring the switches now, and I'm using an IR sensor that has worked for years (so I'll use it on this until I learn I need a mat).

    My issue is what's the best way to create the repeat firing action I'll need? If I was using DC, I would try a blinker relay, but I'm not sure about AC.

    Any thoughts on best practices?

    I would recomend some type of microcontroller, so you could have a random pattern, maybe a random flicker circuit hooked up to a relay?

    If that is too involved try something electromechanical, like a distributor of sorts, or the blinker circuit in a car.

    I have a Santa that blinks. The prior owner wired up a blink circuit. I'll be happy to examine how this was done...you'll just have to be a bit patient. It's in my shed and right now we're getting hit with a snowstorm. Can't get to it yet.

    Default Patience...easy

    I've got about 8 months. :-)

    What is it you need to repeat? If it's just the lights a fluorescent starter flicker setup might work nicely. If it's the motor and/or fog machine the simplest way I think would be to use a blinking LED or car blinker fuse as a switch between low voltage DC and a relay.

    There are also plenty of commercial repeating event timers available.

    However, for the most flexibility your best choice is a microprocessor control system. Have a look at the Prop1 by Parallax.

    to trigger teh solenoid I assume.

    It would look best if its randomly firing.

    Depending on the watts your air valve use, a Christmas light controller might work. Only takes about 10 Min's to modify the light controller and it has 7 different settings.

    If you have a set of Christmas lights that flickers, chases, slo glow......, all you would need to modify the light controller. Is a female plug.

    I use a lot of these controllers to flicker lights and to get a strobe effect from a color light bulb. I use them to fade one light while another one comes on (2 way mirror) or to fade lights on and off down a hallway.

    ACE Hardware, carries a 120v blinker. I had the part number but my son deleted the file it was in. But I like the Christmas light controller because 2 or 3 of the setting will work to blink 120v in different patterns.

    Ace also has a plug in light blinker (Old technology) it warms up then blinks the light(s). just plug it in, then plug the drop cord into it(It's a small, round brown plastic knob-like)
    I bought one just a few months ago.
    There was also a little thin wafer you put into the bottom of a light bulb fixture. When you made the switch blink the light several times it would continue blinking. This was originally made for use by the elderly in their porch light to signal neighbors if they were having a problem.
    This item went between the bulb and the inside of the socket, just screw the bulb in ontop of it.

    Default Thanks

    Yeah, I'm looking for a low-tech solution like a light blinker. I'll check Ace out, I forgot about that one.

    I dont know if this will help you but i discovered something neat last year. I took the cord and controller off an old delapodated heating pad hooked up a flood light to it and what happened was pretty cool it would fade in and when it got to the tem0p it would fade out. I liked the effect
