    Looks fantastic so far, J-Man! Your artistic ability seems wonderfully apparent, to me.
    And good luck with the mechanism.
    You know I love animated props !

    Hey thanks for the kind words DaveintheGrave! Got the new servo hooked up today and that did the trick, plenty of torque.
    I'm pretty happy with the random side to side movement now, just gotta isolate that monster servo to cut down on the noise. I'll try to get a video up soon.

    Hey, J-Man, I love how well your project is turning out, but I have a question for you. Are you using some kind of controller the way Paul did in his video? I really like the prop, but our budget can't handle a pico controller. I really don't care much if the motions are repetitive because for the most part the only ones who see that are the ones who made the prop. Kids are just "WOW"... on to the next thing. I'm just wondering if the tombstone can be a prop we can turn on and walk away from like our cauldron creep or tombstone popper.

    Yes I am using one of my controllers for this with a PIR sensor. I'm actually using one of my Try-Me-Trol controllers with a specialized program on the micro that randomly moves the servo when triggered. This prop really needs some type of controller. If you just let a wiper motor run continuously it's gonna look a bit weird with the face moving in a constant orbital pattern. The PicoVolt controller is $70 so yeah, that a pricey item. The cheapest route would be an Arduino and a 2 channel relay module (about $10 for both). With a randomized program on the Arduino you can run the motor in either direction using the 2 relays. Of course if you don't know how to write code for the Arduino you would have to seek help. Anyway, shot a quick video of "Stone Face" so here's a look.

    He turned out great. I think in some ways he's even better than the original because his face is clearly where your eye is drawn to. That helps make sure that the movement is seen. Bravo on the outcome.

    I will definitely need help down the line when it comes to anything made with an Arduino, but I suspect it's time to dive in. Most of the things I have rolling around in my head involve a bit more than just a wiper motor going around in a circle, but for the time being, I think that's where my fall back position is. Once I get a rolling grave going, maybe I'll get the courage to try a moving face on a tombstone.

    The video looks terrific!
    You're right, the random movement is a lot creepier than a constant motion would be.
    I like it !

    Thanks chubstuff! If you build one with a wiper motor, at the very least you could use an on/off timer module like this:
    https://www.ebay.com/itm/Timing-Dela...QAAOSwW3VavGAv
    That would be better than continuous movement.
    BTW, you would also need a PWM speed control which you can also get on ebay for $5 or cheaper.

    Hey thanks DaveintheGrave! I do like the random movement for sure.

    Thanks for the advice. I think that approach fits into the budget much easier than the Frightprops' controllers.

    Great job on the stone there J-Man. I love the movement of the face.
    People will go did that just move or is my eyes playing tricks on me.
    Stick
