    Default pumpkin patch

    Hello!

    I'm looking to create a pumpkin patch in my yard using foam pumpkins that I carved. I want to scatter them all over the yard and light them up so that they can all be lit up with different colors or the same colors. I was thinking of using pixels because that seems like what I'm looking to do. At some point, I'd like to create a show but for now I want to start small. Can anybody help me figure what I'd need to do this? I attached a picture of what I'm looking to do.

    I'd really appreciate any help!

    Thanks.

    Matt

    you will need two things. pixels and a controller. If you stop there, make sure the controller has some test modes. You will probably want a sequencer and a player. The last items will give you discrete control over the colors and how long to display them. Then you will need miscellaneous but required stuff like power, wire, enclosures, heat shrink tubing, connectors, and communication devices.
    Each of the subjects is whole topic. But if you are just starting and want to finish by Halloween...
    figure out how long the whole project will be. (ie distance between and number of pumpkins).
    buy at least that number of pixels so you can test. i would suggest 12 volt ws2811.
    Get a power supply (12v).
    Do you know how to program? Buy two clone arduinos.
    Do not know how to program? Buy a controller like a falcon 4 port.
    put a pixel in your pumpkin and turn on just one led. are you happy with that?
    cut up the rest of the pixels and solder wire between them.
    By this point, you will either see the finish line or pour yourself a cold one and say next year!

    Don't forget that you'll need lots of time. Everything takes longer than expected, and halloween is only six weeks from now.

    The wiring and power distribution schemes may need to be different from most of the pixel discussions on this site. The reason for this is that the pixels in your pumpkin patch (if it's anything like the photo included above) are going to be hundreds to thousands of cm apart, rather than 10 cm (4") apart as in the usual pixel strings.

    Individual pixels run by arduinos are probably the best, but also, just throwing in several LED's on different GPIO's on an arduino would work, too.

    I know I am going to get "eaten alive" by this comment, but you could also use Dumb RGB for this particular project since all you are trying to accomplish is change color within a prop.
    The one nice thing about dumb RGB modules is that all you need worry about is voltage drop.
    This is the reason I still keep a couple 27 channel DMX controllers hanging around as they would work great for something like this.

    Or orange tea lights (static or flickering).

    Dumb RGB with a Renstick or
    ESPixelstick as a controller playing a sequence from the the SD card with a daisy chain from pumpkin to pumpkin. I suspect you would need 20 or 30 pixels per pumpkin to get some decent light. You might look into Pixel rings or Pixel Modules (blocks of LEDs on a single mount). They might be easier to work with.


    2021 New Tune-to sign. New 40x27 matrix at the house. Retiring the Strip based matrix. Updating some of the old window frames to the new house. Adding two new songs.
    2020 Full sized show reworked for the new location. Only adding (famous last words) 13 RBLs that I finally got converted to using pixels
    2019 - Just moved into a new home (yet another change of plans). Will be dim but not dark. Too much to do at the new place to leave time for a show. Dim show (3000 pixels) had regular visits most nights.

    Oooooh yes. Pixel rings. Now THAT would rock.

    Edit:. argh I'm sorry, I'm not keeping up with the times. I meant that would be sick. That's dope.

    I agree. I have done what the OP is wanting to do but used smart pixels just because I already had them. I have around 10 bullet pixels per pumpkin. Thereís no real effects you can do with the smart pixels inside the pumpkin other than maybe flicker or twinkle. So, if you donít already have smart pixels and a controller and are looking for a really cheap solution, consider dumb pixels.

    I will try to get some pics of my setup this weekend and provide more details on what I did.

    Or, if you just want a "static" flicker effect and you already have a Renard, you can run something like what I did for these candles. It uses a modified Renard code(the same as my RenTester) that literally just loops the out and the in of the Renard.

    I did this at my Mom's house for a couple of years in pumpkins and with candles and it looks really good.
