Hm, sign isn't nearly as bright as I'd hope.
Looked back, and after adding the second stroke on the star I'm definitely running beyond the length rating on the driver. Good news is, I can buy a bigger one that's also supposed to be quieter.
Right now it glows, but it doesn't shine.
I still feel like I succeeded in my mission of "doesn't blatantly look like el wire" :D
Oh also right, this project literally came to me in a dream. Not exactly as implemented ofc, but the concept of an el wire rainbow in etched acrylic channels? Yeah!
