I had several people email me to say that I was just miming to music, and that the whole thing was a fake. So I thought I'd better hire an impartial panel of judges to inspect the evidence.
(Turn the laser power *way* down when trying this at home)

I would have been cool with you saying "Yes, it works" but, no, you had to let Jared waste my precious time I could have been watching videos of animals making noises that sound like they're talking. I thank you for making waste that time.

Seems to have a slight (like 0.2 sec) delay between the moment they hit the "strings" and the moment the sound gets generated.

if i were to help my dad build one i was just wondering- can you make the laser blue? not that it matters that much.

@PipoTachyonYAY You need to purchase a blue laser for that - but yes it will work with any colo[u]r

I'm curious as to how the sensor differentiates between each different note. As far as it would know, it's just detecting a laser, right? How does it know which laser is being blocked?
joegt123 1 year ago
@joegt123 Each beam is the same laser, just being moved very fast. So blocking each beam gives a pulse, by working out the offset of the pulse you can tell which beam(s) are being blocked.
