Author here, happy to answer any questions!
I wonder if white thread would've been more invisible, the black thread seems more obvious against the LEDs? Being nitpicky, its a cool project for a single night.
There's actually a specific transparent thread you can use for this, it's called a monofilament polyester (aka "MonoPoly") thread, in clear or "invisible" variant. Would be perfect for this project.
Just want to say- this is a really neat idea and project!
p.s. thanks for the additional sourcing details
Have you thought about ways to make the lights detachable so you can wash the garment? Or is the trade off at a point where redoing it is easier overall?
It’s maybe plausible to gently wash it with the filaments still attached? I did actually use connectors so the shirt could be detached from the drive electronics, though I’d be a bit worried whether the stitches would survive and corrosion on the solder joints. Adhesive/waterproof heat shrink could maybe help?
The other option is maybe attach the filaments to an embroidery style patch instead of the shirt itself and then attach it with Velcro to the shirt?
Beautiful! Thank you for sharing.
The pwm animation/flicker/ramp up was a REALLY nice touch
Reminds me of a Japanese tech demo on YouTube I can't find right now, of projecting a flexible hologram on to a t-shirt with invisible markers.
