Machines Secretly Talking in Escape Room Technology
Hey there. Drew here.
Take a $1 range finder module, and make a directional ultrasonic beacon WITHOUT modifying the hardware. Lemme show you how...
Glad you asked.
In my formative years backstage technical theater was my thing. I did sound and lights. In college I wanted to grow up and be an "imagineer" for Disney.
Well, I got distracted by about 20 years of engineering work, but fortunately I never grew up. And then recently...
I met Escape Rooms. And escape room technology... oh escape rooms...
If you don't know...it's a blend of theater, mystery, engineering, and puzzles.
So recently I was in a discussion about how one could make a prop. It's a "camera" that needs to "photograph" different objects. When all the objects are photographed, something happens. (I'll spare the mystique and keep to the engineering here.)
You could do it with actual photographs and machine learning. But how else?
I got to thinking... could you make some sort of side-channel where the "camera" and the object negotiate and agree that it has been "photographed". If so, no actual photo is needed. No machine learning, no servers.
So what if you could make an ultrasonic (or IR) directional beacon and have the "camera" know when it is pointed at the object (and the button is pressed).
How could one try this out really quickly? How fast could you get the technology working so you can get to the real question--is it believable? Because, after all, the real test is whether it blows the socks off the escape room guests. This is a case where the technology needs to be powerful, yet invisible.
Check out a short video here. (There are some small details on the oscilloscope to see, so you might want to full-screen.)
BEFORE YOU WATCH, lemme explain something.
I mention a previous video. The previous video exists in this following Facebook group. Join. You'll probably love it.
