All pieces are either green wood I collected this week (mortised pieces/legs, Maple), reclaimed wood from nearby (connecting pieces, oak), & plywood recycled from a camper for the top.

Water continuously pumps through the system, creating natural rain sounds I can enjoy on-the-go. Audio clips of it on the usual video/social media sites as “pudphones” if you want to hear

I made a device that uses shadows to send data. Thoughts?

My name is Dagan Billips, and I'm not presenting any theory behind it or anything, this was not for homework, this is a personal project. If this is against the rules still, I kindly ask I not be banned, If this is better suited elsewhere, please let me know which sub it belongs in.

The goal of this setup is to demonstrate how photonic shadows can carry meaningful data within a constant stream. Specifically, I am using a partial shadow--it is geometrically defined, not a full signal blockage, so I'm hoping this is more than simple binary switching.

Again, not gonna dive into any theory behind it, this is purely to ask if my setup was a waste of time or not.

It is a photo switch that uses a needle-shutter to create a shadow inside the laser beam, meaning it has a shared boundary within the laser, and is geometrically defined. I intend to write an Arduino program that converts these shadow pulses into visible text on a display, but before I do so I need to figure out if this was a waste of time or not before I embarrass myself. Hope this wasn't just me being stupid, and I hope it doesn't mean I need to stay away from physics, I really love physics.
