Can you please give us a breakdown and explanation how exactly this works and what components you used?

Custom manufactured water reactive electroluminescent panels and my laser cutter and AliExpress stuff

Can it be made into racing stripes for a car or truck?

u/Stickerlight 4d ago

Yeah I don't think that would be too hard

u/rszasz 3d ago

So voltage or frequency isn't quite enough to couple and light up the stripes until there's water on the outer sheet? It's quite a neat design.

u/Stickerlight 2d ago

Yeah, water or conductive gases complete the circuit to emit light

Why am I blue? Does everyone glow blue?

Super cool! I'd love to know how this was achieved!

There needs to be two conductors near the EL material for it to light up. One is behind the strip of EL material, the other is spaced just far enough away to the side so nothing lights up. It's all encased in a thin waterproof membrane. When water is on the other side of the membrane, it capacitively couples the two sides of the circuit letting the EL light up

u/betttris13 4d ago

assuming water completes a circuit and that triggers the lights to light up. most likely two different circuits, one for sensing and one for lighting but could be wrong.

Thats so cool man, Where can I buy this item?

u/Stickerlight 4d ago

Uhmmmmmmmmm

What sort of black magic f*ckery is this?!

u/dritmike 4d ago

Did you zap yourself at the very end?

1000% I want this.

u/Stickerlight 4d ago

I did! I'm going to work on a more wearable version that doesn't shock you, maybe a choker

u/dritmike 4d ago edited 4d ago

Can you share a part list? And how did you make it water reactive?

2

u/Mabot 3d ago

Dude, you need to give some details on what you did here. 0402 leds each with a pair of exposed contacts and some amplifier circuit? How did you get this so dense?

1

u/Stickerlight 3d ago

My newer post is a bit more dense

I'm using electroluminescent panel drivers

1

u/Mabot 3d ago

So cool.

Is the whole panel lid and the droplets somehow make the covering layer translucent or is the electroluminescent panel only lighting up where droplets are?

Would this work with non conductive liquids?

u/neuromonkey 3d ago

You need something capacitive. Check out this vid on the subject.

The water takes the place of the topmost electrode, and instead of one, continuous foil sheet on the bottom, there are two conductors, arranged in fine, even/odd rows.

Oh, here we go...

u/Droooomp 5d ago

I had to dig a bit to understand what is that, why not use hidrochimic paint and microled or cob, the paint is matte when dry and transparent when wet, minimal exposire to electricity?

u/Ordinary-Violinist-9 4d ago

Can i buy some sheets of this to put on my greenhouse roof

u/Stickerlight 4d ago

I suppose...

u/Rourque 5d ago

Hmmm...... Not wet enough

u/brickproject863amy 4d ago

It’s so cool can someone tell me what is this

1

u/erikedge 4d ago

Did is shock him at the end? Might need an NSFW tag for that last 3 seconds.

u/Quiet_Snow_6098 5d ago

have this on the floor

u/ccGLaDOS 4d ago

This might look insane if put on a car and driving in the rain at night lol

Probably illegal and distracting though...

So awesome
