• Gravity Well Machine U...
Sometimes we humans need to build machines with the sole purpose of demonstrating the effects of gravity on a steel sphere. This is a machine that happily fulfills that purpose. Be mesmerized by the combination of engineering and physics resulting from the simple motion of a ball rotating around a gravitatonally shaped dish. Watch as the steel ball bearings gain potential energy as they're being lifted by the grain elevator, only to be converted to kinetic energy as they roll around the well and tumble back to the bottom.

So you know these ocean drums? It’s a type of percussion instrument that mimics the sound of the sea. It is a circular frame drum with filled with small beads. When the drum is tilted back and forth, these beads roll over the bottom head, creating a sound similar to waves crashing on a beach. This could really be a fun project for thousands of tiny ball bearings. Getting an interesting mechanism that can lift different sides of the drum. Playing around with overlaying oscillations to check out the visual movement and the resulting sound of the beads. Maybe capturing the essence of the mesmerising movement of the strand beasts and the calm ocean currents.

[@Engineezy]

Love it! Gonna have to do some research on these drums

BRRRRRRATATATATA BE GONE HATERS, YOU SUCK!@@Engineezy

[@TankR]

The white noise of the machine is deadening and taming down the input to the brain, which filters out things it experiences consistently for the most part. Otherwise you would feel every hair on your body....as they grew.... There is app Ive used a few times that seems to just play a tone at the tinnitus frequency you perceive, and its worked on some level to deaden it. Basically I assume it sort of 'overworks' your brain to the sound so as the brain compensates it becomes less pronounced, like if you were to use a green/blue light in a room for some time then go out into a white lit room it would look very redish because your green and blue cones have been working but not the red ones ergo the reds are primed to sense light where as the blue green ones need to even back out both in their chemically driven photon to nerve impulse sensing and perceived sensation in the brain. Brains are weird. For the tinnitus anyways, I imagine a tone generator would have the same effect. Havent tried it yet though....

[@Rocky-917]

Hey man, you're really inspirational. I feel pretty discouraged from trying to make things because it feels like I don't know how or wouldn't be able to figure it out. But watching you just problem solve and makes stuff work makes that process seem more doable. I appreciate that a lot.

[@Engineezy]

Glad it inspires! One of the main reasons I make these vids

[@friendsbrn]

My struggle is my perfectionism and intense desire to do things "the correct way". Sure, my solutions often have significant longevity, but complete implementation is my struggle as I often fail to get to the end. To JBV's point, "it doesn't matter how you get there as long as you get there". Too often I let perfection be the enemy of good enough.

[@darrennew8211]

That's fantastic. Imagine having this in your garden where you'd otherwise have a fountain or birdbath.

[@haydenlewis2788]

Excellent work as always... the only thing that surpasses it is the entertainment value of the video!

[@Engineezy]

Really appreciate that!

[@Graytail]

Another idea - auto-pachinko. Feed into a horizontally sliding chute at the top of the machine that will deposit the BBs into the pin-field. Rig it so that once the middle catch area fills all the BBs are drained from the field and recycled. Potential for pinball style lighting here if you give the pins a metal ring around their bases so that the BB completes the circuit for a light. Other possible inclusions - rotating sections of the pin field, automatic pinball flippers, archemedes screw lifts running up both sides of the play feild so you can watch the BBs get raised back to the tank at the top.

[@Engineezy]

Oof you got me on the auto flippers! Endless chaos

[@_Doodle-bob]

Not going to lie, my favorite part of this video is watching the balls bounce off the hopper in front of them as they get dumped.

[@adamtreen-noaafederal1354]

Yes! I thought the same!

[@benmcreynolds8581]

This reminds me of how much I Loved those Penny machines in certain stores when I was a kid in the early 90's. You'd launch a penny down a ramp and the penny would roll on it's thin edge all the way down this gravity well shaped object. It's so fun I wish they would come back!

[@Engineezy]

Those were the best!

[@MakewithMatt]

Awesome video thanks for sharing! Definitely the most satisfying thing I’ve seen today! I like how the smallest balls sounded like a rain storm. A rain machine would be cool for the tiny balls but that seems way too simple for your mad skills. I’m sure you’ll come up with something awesome and I can’t wait to see it!

[@DoremiFasolatido1979]

Your best results on the center of the well would be to make it an aperture that can fit 7 balls at a time. Essentially a perfect hexagon of balls. One in the middle, six around it. That means, no matter the rate you drop them into the well, it should never get stuck or slow down. A slightly steeper beginning incline from the outer edge, as well as having the wall meet the incline being rounded at the same curvature as the balls, would make for a slightly smoother and earlier descent into the well. It's like merging on a highway, you need the balls already on the track to get out of the way of those coming on. They'll bunch up less and have a much smoother trajectory into the well at the center.

[@locomotioncreations]

Love it dude! You did not lie; This is easily the most satisfying thing ive seen today! 😊

I bought that gravity well stl from you and I took the well and cut it up into 8 pizza like slices and increased their size by 250 - 300 some percent. Filling up my printer bed as large as I could each piece, then connected them together with crazy glue. No need for sanding as they came out smooth and level by printing on their side.

For the tiny balls you should make a ball bearing "wave pool" using one of your mechanical wave designs to manipulate a thousands of the B.B.s hopefully making them look like a low particle fluid simulation.

[@obelisk398]

please coat the gravity well in silicone so there is constant friction on the marbles

[@Engineezy]

Might make for an interesting result!

[@djohnsto2]

That's pretty cool. When the balls go around the well they form what look like statically-rotating patterns - The position of the balls relative to each other is more constant than I would have thought.

[@Engineezy]

I hadn’t thought about that! Very interesting indeed

The tiny balls are so much more chaotic and indeed answer one flaw/question that I had regarding the gap when the scoop is overturned. Many balls just dont fall in the hopper! So make a short with some fix for it maybe lol. Anyway can we say a marble version for this? I'm sure so many marble run channels will be thrilled to have this and include it in their runs!

[@Engineezy]

Yeah, the small ball were an afterthought, I think with a slightly different scoop design, it would quickly solve the problem! I think it would already work with marbles if they are the right size!

idea - How about some sort of BB fountain, which you can hang glokenspiel bars, or bells about so the balls can hit them on their way down before getting recycled

[@Engineezy]

Love that idea!

You want a convex outward crown on the center of your rollers, not a concave inward one. Its kind of counter intuitive just looking at it (you have to think of the elastic effect and the tension in the material making it creep around a tension gradient for it to make sense), but the material will want to ride up the curve to the high point, especially if it has any stretch in it at all. I use this all the time for keeping rubber bands on a motors shaft, just a little doodadd on the shaft that has a slight center bulge and they wonder right back to the middle!

[@Engineezy]

I actually ended up going with convex! Saw the steve mould video about it!

I really enjoyed watching this, thanks for the video. For some reason(because it bears no resemblance at all) it reminded me of a toy I had in the 1970s called cascade by matchbox. I was wondering if the idea of that toy could be elaborated upon. It uses drums for the balls to bounce on but the drums are level, maybe they could be put at angles instead. Or use a number of drums made to different notes so that a stream of balls would play a tune. Keep up the great work mate.

If you want to minimize your top layer count *and* reduce infill density *and* prevent that pillowing/quilt effect on your top layers, then the rectilinear infill pattern is really hard to beat. There are a few infill patterns that increase in density towards the top e.g., adaptive cubic and lightning, but rectilinear is dead simple and has a more uniform strength profile.
