    J-Man replied to a thread Pneumatic: how is this movement done? in Halloween Props
    Just a suggestion on triggering, I haven't seen your Trash Can but if it pops up quickly, you may wanna keep the trigger in your pocket if there's any chance someone could be directly in the way. You don't want someone leaning over it when the button gets pushed.

    Currently any multi-channel audio file will only play back in Audacity as 2 channel stereo. Like I said, it will record up to 8 channels but it can't play it back, pretty dumb but that seems to be the case.

    Yeah, I just did some research, looks like currently Audacity can record up to 8 channels but can only playback in 2.

    Have you tried playing a 4 channel file directly from Audacity to the Behringer?

    I believe the Behringer is USB input and then splits the channels.

    I don't own any Behringer products but I believe you would be able to play your custom files right from Audacity and into the multi-channel output Behringer. The down side is this gets a bit cumbersome outdoors with a PC and all the wires.

    Behringer makes some good products for multi-channel audio. The info here may help out. https://www.gearank.com/guides/audio-interface

    Plug-ins allow Vixen to control a variety of devices. I use Vixen for servo control with the EFX-TEK HC-8.

    Looks good but it does appear a bit weird with the whole spine moving back and forth with the head. I would secure the spine so it's stationary but again that's just me. (OCD) :eek:

    While just about anything is possible, I'd try to keep the motor up top. That being said, not sure you'll get enough swing out of this for a trapeze.

    J-Man replied to a thread Pneumatic: PIR sensor on a picoboo in Halloween Props
    As I mentioned a couple times, if that negative output of the PIR is switched (normally not connected to ground) then it will work as is. If the negative output of the PIR is always ground, then you will need to add an NPN transistor.

    J-Man replied to a thread Mechanical: Wiper Motor Question in Halloween Props
    Ahhh, but that's the big advantage with PWM, you don't lose any torque from the motor. Simply reducing the voltage to slow the motor does result in loss of torque but PWM does not.

    Well again, unless the negative output of that PIR is switched, I don't think it will work without adding a transistor.

    Got a link to the 12v? Again, if it outputs high, I don't think it will work directly with the Picoboo.

    J-Man replied to a thread Pneumatic: PIR sensor on a picoboo in Halloween Props
    If what you have is a PIR module, it probably outputs 5 volts positive when active. I could be wrong as I don't have one but I don't think the Picoboo trigger works with a positive input. You may have to add an NPN transitor to supply a negative input to the Picoboo.

    J-Man replied to a thread Mechanical: Help with cauldron creep head movement in Halloween Props
    Here's a diagram showing the difference in pivot point location. The first example has the pivot point above the arm being moved, similar to bluesjumper's configuration. The second example has the pivot point in line with the arm being moved. The blue lines represent the distance the linkage has to move to get 90 degrees. Using the same linkage attachment point in both examples you can see that it takes nearly twice the amount of linkage movement to get 90 degrees with the arm below the pivot...

    J-Man replied to a thread Mechanical: Help with cauldron creep head movement in Halloween Props
    The other thing that's killing the movement is the tee configuration. The pivot point is way above the pvc that you're moving, so the whole assembly is acting like a swing instead of a seesaw. You'd get much better movement if you use a 4-way fitting between the shoulders and get the linkage connection point much closer to that pivot point. Your motor arm is only giving you a set amount of movement in 180 so the closer the linkage attaches to the pivot point, the more movement you'll get. You...

    J-Man replied to a thread Mechanical: Help with cauldron creep head movement in Halloween Props
    Really hard to say from here but I would do away with the double linkage and try a single bar from the motor arm to the pvc. You really need to start by positioning the head upright where you would like it to be at the highest point and then configure the linkage from there.

    Easy, a power inverter. Just make sure you get one that has more than the required wattage your device needs. Here's one. https://m.harborfreight.com/750-watt-continuous-1500-watt-peak-power-inverter-66817.html

    What's powering your Creep, 120vac? You just need an AC to DC power supply. Anything from 3V to 12V will work, such as an extra phone charger. Those "battery" LED's you've shown are nothing special, they're just standard LED's with resistors to accommodate the 9 volts, so don't waste you're money. Look for 12v led's on ebay if you don't wanna mess with adding resistors. They have resistors already added to handle 12V. They will also work with 9V -5V though they might be a tiny bit dimmer,...

    Not really sure what you're asking. Any LED can be powered with any DC voltage using the appropriate resistor.

    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....
