    Just an FYI, I am completely sold out of the Squawker Talker controllers. If anyone is interested, I am taking pre-orders for a second run. When I get at least 5 pre-orders I'll order parts for the next batch. Thanks everyone and let's see some more videos of your Squawkers in action!

    PWM is short for "pulse width modulation". It refers to an electronic circuit that controls voltage output by turning the power on and off rapidly at an adjustable rate, which in turn, controls the motor speed.

    A wiper motor with the "park" feature still needs a controller. Just a motion sensor won't control the motor.

    HauntedWyo, Kinda off topic here but just wanted to throw in a quick warning about oscillating fan motors. A lot of them rely on the air moving over the motor to keep it cool. When you use the motor without the fan, they can overheat pretty quickly. Some have had success using those motors, others not so good.

    Well, as for prop controllers, everyone has their own preference and there's a ton of choices. I'm not gonna suggest any particular type or brand, the choice depends on your skill level and what future props you might use it for. Do some research on prop controllers and make your own decision would be my suggestion.

    First off, to do what you've described requires a bit more than just a motor and a motion sensor. There has to be some type of controller to execute the sequence so it always resets and stops with the arm in the down postion. Just wanted to point that out before you invest in another motor.

    Here's a video of a Squawkers trio I just finished up performing "Somebody's Watchin' Me". Each bird has it's own Squawker Talker board. The audio in the video is coming from just the speaker in the center bird. There are 2 MP3 players that start simultaneously to handle the 3 tracks necessary to pull this off. Tracks were created with 12khz sine wave segments using Audacity.

    J-Man replied to a thread Mechanical: need help one my first wiper motor in Halloween Props
    That's great but as I mentioned at the beginning, the slow speed may have worked depending on what the prop is. For any "stirring" prop, you're gonna need to slow that motor down to about 6 rpm.

    J-Man replied to a thread Mechanical: Lunging Clown Head Prop?? in Halloween Props
    Always good to use what you have on hand but I would think 3/4"x1/8" flat aluminum stock would be plenty for this while keeping the weight and bulk down.

    Actually, Fright Props has a really good price on polyethylene tubing. $28 for 100' of 1/2". http://www.frightprops.com/pneumatics/tubing-for-push-in-fittings/polyethylene-tubing-0714-0009.html

    J-Man replied to a thread Pneumatic: Air tanks in Halloween Props
    You won't get pressure drop even with 1/4" tubing, the problem is volume. The nylon tubing from automationdirect is a little cheaper but not much. The polyurethane tubing is really nice stuff, very flexible and doesn't kink easily. Another thing to consider though is the possibility of mice in the off season, they like to chew on that tubing.

    J-Man replied to a thread Pneumatic: Air tanks in Halloween Props
    Not sure that cheap tubing in the link is suited for pneumatics. You want polyethylene (most cost effective) or polyurethane (more expensive but much more flexible). Here's a link to a good supplier, prices are hard to beat. https://www.automationdirect.com/adc/Shopping/Catalog/Pneumatic_Components/Flexible_Pneumatic_Tubing_-a-_Hoses/Straight_Polyurethane_(PUR)_Tubing/1-z-4_inch/PU14BLK100 Should you decide to plumb your building, you're gonna want 1/2" for long runs, 1/4" won't handle enough...

    BTW, goes without saying, that power supply has to be kept dry.

    No shock risk at all, they run on 12VDC. As with any electronics, they do need to be kept dry.

    The stand alone tank idea won't work for this type of prop. That needs a steady supply of air.

    Without knowing what his application is you can't say this is a bad idea. I do this with some of my props that don't need a lot of air and it works perfectly for several hours.

    That's all you need. Just be sure it's at least 1A (1000mA).

    I don't have the 5 gal tanks connected to a compressor, they're stand alone. When they need refilling I disconnect them and refill.

    J-Man replied to a thread Pneumatic: Air tanks in Halloween Props
    That's pretty much it, you just have to try it out. Put a regulator on the prop and turn the pressure as low as you can and still have the prop operate. Also important to make sure you don't have any air leaks, even a small one will drain the air supply pretty quickly.

    J-Man replied to a thread Pneumatic: Air tanks in Halloween Props
    There's really no formula for calculating that, all depends on what pressure the cylinder needs and how often it cycles. I run several props with 5 gal tanks, (each prop has it's own tank). Some will operate several hours but they only cycle every ten minutes or so and don't use much air. You just have to try it with your set up and go from there

    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....
