I used 5mm rgba strips like this www.amazon.com/WS2812B-ALITOVE-Addressable-Programmable-Raspberry/dp/B07R6LR7DK/ chained in a zig zag matrix, driven by an arduino-type microprocessor with hard-coded flame animation frames in the program. The strips were arranged on a few pieces of stiff wire and the lighting part was wrapped with fake spiderweb material. I think all the rest of the materials are in the description. A good place to start from is this project learn.adafruit.com/animated-flame-pendant my version just scales it up a bit using the neopixel library and some arithmetic.

What's your question? This is a costume piece I constructed for a children's production of Beauty and the Beast the musical.

it would be a very interesting experiment. You'd need to put a hole through the back to the non-glowing bus layer, but not go through it at all, heating up something blunt might do it. The panel has one big flat bus in the middle and a long skinny bus around the edges that connects to the ITO coating, the invisible top electrode, usually in one place the big bus panel goes out through the side to where the plug comes at the factory. You'd need to keep at least some of that skinny outside bus somewhere on your finished piece to attach the second electrode.

I'm just using a pocket inverter, it converts 2 AAs to >100vac at the correct frequency. Check adafruits EL panel product page for detailed specs.

I've never attempted soldering, I would expect the plastics to melt. The current is so low that any conductive ink that sticks will work fine, if you don't have any conductive ink you might even be able to use a few drops of water and a drop of elmers glue mixed into some finely ground pencil graphite.

With some beefier motors, you could raise and lower real pumpkins, but I highly recommend carving them from styrofoam so you don't need a such a loud motor to move them around. If you make them out of foam, you can pre-shatter them so they explode with yarn guts but can be put back together like a jigsaw puzzle. I used an I/R led to make the pumpkin trackable too so I could project a face on it :) biluminal.com/2019/10/29/infrared-tracking-projection/

Sure, it's a somewhat complicated project as a whole, which part would you like me to explain? I used a cheap L298N stepper controller from amazon and a stepper that matches it. An arduino nano serves as the brains, i used 2 4.5v AA holders for power (in series to make 9v), to keep the profile low, and a very common serial-to-dmx module to receive signals from my light booth software. I'd be happy to share code, wiring, whatever you need.

wltd.org/blog_images/arduino_dmx_bb.jpg this shows how you wire up dmx to the converter, you can connect to any serial you want on the arduino. The ground path is wildly redundant in the wiring example here, you can just connect XLR1 to ground on the converter to both DE and RE pins to keep the converter active, i always do, you dont need 5 wires going to a breadboard.

That's great, I'm glad the video was helpful! I love working with little peices of this stuff and the www.sparkfun.com/products/10878 EL Escudo Dos shield to do animations :)

That's a great point, I could solder the wires to the copper first, I think that might be better, as long as I did the soldering on a hard flat surface. I could use epoxy, but I find it messier and slower. Usually when I am making my own pads like this it is because i am cutting half a dozen peices of panel that I plan to animate and/or separately mount on a fairly rigid surface, and superglue and tape seem to be about the right about of time and mess for those purposes. If I my peices were going to be flexing or the wires were going to be moving around, I think the epoxy would absolutely be better.
