What’s the big circle on my wall?

What’s the big circle on my wall?


cool hey guys Devin here with make anything now a lot of you in previous videos have seen this giant disk on the wall and you’re asking me what that thing is. Makes sense, it’s pretty funky looking and I think it’s time I explain. After all, it is one of my very favorite projects that I’ve ever done. A few of you recognize that this is in fact a double pendulum, which is a really cool mechanism that demonstrates chaotic motion. That means even a slight difference in how you swing it will lead to wildly different results. I made these arms by laser cutting smoked acrylic and then I fit some skateboard bearings in them to make them rotate and then also have this 3d printed structure holding in place. Now double pendulums are super fascinating as they are they do some really crazy movement like that you see that of this weird there’s a lot of weird stuff and I wanted a better way to visualize it and that’s where this becomes extra cool this is a little battery pack that I 3d printed to hold two three volt button cell batteries it’s also got little slots to hold onto an LED now this isn’t your ordinary white LED in fact this one and miss light at a wavelength of 405nm putting it on the UV spectrum now this entire disk is coated in a photo luminescent pigment otherwise known as glow-in-the-dark paint combine that with the UV light and you’ve got something kind of awesome how cool is that and it only gets crazier when you turn off the lights so UV light glow-in-the-dark paint and a double pendulum do you see what I’m getting at here oh yeah good the bottom of pendulum in here is made just the right size to hold onto this battery and the LED there we go we now have a very cool way of visualizing the path that this double pendulum takes so I don’t give this a quick spin and then we’ll turn out the lights so you see why this is one of my favorite project it is especially cool especially person not to make you jealous now if you like me you could probably watch this for hours and that’s why i made a second video of just the pendulum ringing nonstop for a very long time so you have to check that out in fact why would make a little game out of it how about you guys find a really cool moment eating the pendulum swinging and link to it in the comments of that video which everyone gets the most likes i will send this awesome little glow-in-the-dark coral reefs that I made in my scribbler 3d video i think it could be fun especially since there are some really weird movements that this double pendulum does as you guys will see if you guys are like one of these one day make sure to check out the link in the description where I have a little product page setup for this Angeles and you can sign up with your email to get notifications if anything ever happens with it i think it could be a good kickstarter campaign all right guys there you have it one of my very favorite project Angeles until next time I’m Devin this is make anything, stay inspired
