    If you're looking for something top shelf, Poison Props or Scare Factory.

    HH, Again, purely speculation but I would think the cables attached to the bottom of each side would be to limit how far the box is pulled open. MMSH, The Ikea scissors are probably way too stiff for this, the pivot point has to be nice and free. Scissors are easy fab with flat stock aluminum using hardware with nylock nuts.

    Purely speculation but I don't think there's any wires involved. Definitely an aluminum scissor mech with either solid linkage or springs to each side of the box. If you watch the video closely, just a slight inward movement of the box halves retracts the head pretty quickly.

    If the power supply has the available amperage, a second is all it takes. The windings in those little motors are like a thread. Retro fitting with a more robust motor/gears is a good idea.

    No, I'm talking about using a 12 kHz sine wave to create the "talk/sing" channel. It's a bit time consuming, you have to insert a varied length segment of the sine wave for each word/syllable. Danski did a few tracks for his Squawkers with that method. He has an audio software that allowed him to easily pan the sine wave on and off as the track played with very good results.

    The other way is to create the "talk/singing" track using a sine wave segment. The length and placement of the sine wave is inserted for each word/syllable in the song. I've done it many times with both methods and they both work very well.

    Unfortunately there isn't a software to accomplish this, at least I have never seen one. There are ways to get the results you need. Doing your own vocals on the "talk" track is one way, but you have to use ear buds and listen to the track while you're doing it.

    I only have 8 of these left and won't be doing a second batch unless there's a demand. If you want one (or more) shoot me a PM or email. Thanks!

    J-Man replied to a thread Electronic/Software: DC motor control question in Halloween Props
    Ahh, that info would have been good to know before hand. Still, 12v should not have smoked the motor. If the motor turns to a certain point and then stalls, available amperage comes into play. If the 12v power supply had decent amperage, a stalled motor will draw that amperage and that's what likely smoked it.

    Just curious, you mentioned in the first post that the motors worked and the head turned, reverse the polarity and it turned back. What voltage were you using?

    Sorry about that, 3 additional volts shouldn't have smoked the motor. You're probably right about the original circuit knocking down the voltage to the motor.

    For a fire pit the skulls don't have to be perfect, they should look a little deteriorated from fire anyway.

    3 additional volts should be fine, besides, you're gonna slow it down with PWM from the board.

    J-Man replied to a thread Mechanical: need help one my first wiper motor in Halloween Props
    If those 2 wires work with the car battery then bfjou812 is correct, your power supply is not providing enough amperage. Not all power supply ratings are accurate, the stated 5A may not be true. With that being said, the slower speed may very well suit whatever prop you have in mind, build the prop and then move on to the proper speed.

    Hey thanks! I used a Pose-N-Stay which doesn't have free joint movement unless it's modified. The feet aren't tied together, it's just the natural way the legs wanna go when he's sitting. I don't think free movement at the knees would affect the swing, it should be fine.

    Smear a little vaseline on the square hole before you glue it together, that should prevent any glue from getting where you don't want it.

    The washer won't touch the shaft, it will fit over and around the center hub of the gear.

    J-Man replied to a thread Pneumatic: Help with Air Cannon in Halloween Props
    Glad you got it working. When something has been working fine and then stops functioning, the first thing to do is take a step back and look for anything that may have changed. Parts do go bad but if something is different with the setup, 9 times out of 10 that's the culprit.

    I tend to agree with bfjou812, try a car battery directly to the solenoid without the controller. If it still doesn't work, it has to be the valve. When you say the solenoid has been switched out, do you mean the entire valve or just the solenoid?

    Hey Jman! This may sound like an ignorant question, but the light fader you have- can it be hooked up to those led strip lights? If so, how? Im interested in those....
