Invisible data transfer through laser light being displayed as music, when laser is blocked the music stops.942 views. Pretty dope to see

I need your YouTube algorithm

woa ey @laser_lew check it

This was my 6th grade ( 25 years ago) science fair project)

They cut a toslink cable in half?

Wait until he hears about WiFi!

Is it transferring data or is it just stopping/ starting? Looks like a solar panel for a yard light. Maybe it's acting as a relay to close the power circuit

poor man's TOSLINK - only impressive part is it looks like someone created this from scratch, for fun. Respect

942? Now we’re cooking - we gotta bump that up to the 100Ks. I’m on it 🫡
