Is it practical? Does it work? Who cares! Haha 😄 I had a blast on this one.

Fun stuff!! From here it's either a fully motorized active gimbal with inertial measurement... or printing a sippy cup lid.

I've fallen down the Tyler Bell rabbit hole today. I've watched like 5 of your videos. Great work, keep it up!

I feel like all of this could be avoided by just drinking from a bottle instead of an open can.

Oh man I hope you keep upping the game on this on. Next time you need to get some stabilizing motors in there so it self levels! Pop an Arduino on etc... Nice shirt BTW 😉

Maybe a stationary counter weight at the bottom of the “gimbal gage” could help

On the 2 axis there isn't any resistance to changes in direction from the road and the sloshing of your drink. I'd like too see a ver 2 of this though, give the 2 axis a return spring and a dampener and you should see a better result.

The shock absorbers would definitely help as would a simple elastic string limiting the bottom. But, is it practical? Heck no but, that doesn't mean it isn't cool!

6:00 A cup in a gimbal is a two-axis pendulum. When the CG is near the pivot, the pendulum is short and swings very quickly. When the CG is far away from the pivot, the pendulum is longer and takes more time to swing. When the mass centered around the CG is greater, the pendulum slows further still. Angular momentum, rotational moment, and inertia are the main concepts at play.

A rubber band around it all would probably keep it from swinging too far. Some spring effect. Though I think it would be cool to see that weight as a large magnet and have a magnet in the base that it’s attracted to. Maybe it will be attracted to the one wheel already

Dude, you are the best!!!

Maybe a little more resistance in the pivot points?

3:46 third axes would actually be in the center vertically, so it would just spin around it's center and it actually wouldn't do too much. Or maybe it was intentional to say that up and down motion, bc it makes more sense (as you said it would have to be different for every drink, but it would make sense more than just spinning the can)

I would think just some tiny shock absorbers (like from an RC car) would reduce the amount of swing. I think the weight just adds to that. Also, it was really cool to see that steel encapsulated in the 3D print. What slicer did you use?

Love this content, came from your Instagram! You've gained a subscriber today, keep making great onewheel and 3D printing content!

The key would be some sort of damping to slow down the swings not just limit them or store energy like in a spring. Maybe some drag on the pivot points could calm things down.

"Ey man my feet are parched, give me your electric wheeled foot hydrator."

Or you could, now here me out, put in something with a lid. A little crazy I know but I think it might work.

I can't believe you have 22k subscribers... The quality of your videos is just insane and your projects are so cool everytime! Greetings from Germany

you deserve way more subs, the quality of these videos is amazing!

What brand is that fender?

Such a fun idea.... That will work! I love it! Fork holder next? Great job!

What camera are you using? Your shots looks beautiful

Hot DIggity!! That was super fun to watch, I loved the way you used the soldering iron with the brass inserts. So simple, yet so clever. Also if I ever get a Onewheel, we'll have to go on a ride :)

How have I just now found this channel? I love it!

An idea worth further investigation, could be of great benefit to beer drinkers 🍺 I thought about buying or making a steadicam type jigger to mount on the ride on mower so i could enjoy an ale while mowing. Maybe you could do the experiments for us. Enjoy your channel Tyler👍 Cheers from Tasmania

Is that the bpa trail?

Hahaha this was a fun one! Thoroughly enjoyed the story line. We think the next obvious step is to get a microcontroller and servos to auto correct the swing from the gyro motion😄.

What watch is that?

Awesome stuff Tyler! 😃👍🏻👊🏻 ....I wonder what kind of shots you could get mounting a camera and stabilizer to the onewheel? 🤔📷 ..... Also curious to see how a helmet mounted drink stabilizer would work out! 😁

Did you try having the two holding points facing the other way so the holding points would be facing out instead of inline with your legs. Not sure if it would do anything or not

Tyler, how are you liking your onewheel? I’m on the edge on if I should get one myself

you do need to create a soft suspension on the Z axis on the pillars that support the gyroscopic holder, but make sure its sturdy enough to prevent bending

Is it any more effective than a solid mount

Just wondering would having a magnet at the bottom stabilize it at all

I learned this from mowing the lawn on a riding mower with a cupholder... the vibration will make your carbonated beverage go flat before it gets warm... Fun video!

Nicely done and documented.

Fun project! 🛠️👍😁

DUDE! Just started watching but I had to look for it. I was SURE I was subscribed to you... also pretty surprised this has less than 400 views 🙀🤷🏻‍♂️

How about adding a fast spinning gyro/fly wheel to counteract the changing forces while driving?

Hey! I love the video! I know this is kind of an old one but do you think you could put the STL files online? I'd love to make this!

I like what some people have been saying about using motors to stabilize it. I think one problem right now is that the weight does give the gimbal a lower center of gravity and it does help it return to center, but it doesn't control how violently the cup will move. Stabilizing motors would definitely help, or you could try adding some resistance springs in the joints? Because right now, if the cup swings one way, as it returns to center, it's momentum will still carry it in the opposite direction since nothing actually slows it down. So if you added springs or counter torques to slow the movement across the axis as the gimbal returns to center, it would help mitigate the movement, so you don't have as much oscillating movement that just goes back and forth non stop.

Great thought process!

Love the vid man what helmet is that it’s really dope!

Damping damping damping! You really should try adding a rotational damper! That should keep it from overshooting on sharp turns.

Fell into a bit of a rabbit hole , prolly gonna watch all the videos binge style , my question is , what was that brass melty fastener thing ... I thought they were set screws, then I saw a soldering iron type thing to melt em and it threw me off ... I could prolly google it , but I doubt “brass melty soldering iron thingy” will pull much up

Neodimium magnet damper in the bottom of each gimble?

I thought of this a few months ago while ridding with a coffee. As I was watching your video I was like dang that’s exactly what I thought and when you came to the problem with the can not being able to go up and down I was like shocks use rc car shocks. Great video.

Love it lol.

The strong magnet idea is a good shot, it would provide a restoring force, effectively damping the motion. You already have the steel there so as long as its the right type you don't even need to change the cup.

I think having the center of rotation above the can would help, in all anti spill gimbal designs, the can is always pretty far below the center of rotation, however this adds a lot of height to the gimbal.

Probably way too late to consider doing it but if you had replaced the piece of steel with a block of copper or aluminium and put a nice sized rare earth magnet under the gimbal you could use the eddy currents as a passive damper.

could you provide the 3d models?

Man now I want a one wheel

Try coming up with and printing a small, lightweight lid to fit universally on the cans? It’d be pocket sized, cheap, replaceable and then you could use the hard mount without an issue

I suggest 2 magnets directly centre underneath the can holder and the top dead centre to make resistance to slow down the gimbal effect on the drink.

the problem is that the surface of the liquid is above the pivot so the liquid above the pivot is being forced opposite of the movment of the can you culd also add some friction mounts in to dampen the rotation and a shock mount in the base

Where did you get all of these tools? you have a dream workshop

Since there's already a big chunk of steel in the holder it would be easy to add some magnets to the fender side to help keep it upright and not swing so wildly. Might have to experiment with different configurations or strengths but it should help.

We came up with drink holders for our one wheels like a year ago

I think adding a single rubber band to the bottom would solve the flipping over problem, sick video 👍🏼

You need more subs. I subscribed with my 3 alt accounts. Also I wanted to say with the rigid mounted cupholder they make caps you can put on cans and a little mouth thing slides out so you can drink it still.that are like five dollars and if you bought one of those the rigid way would totally work.

Your background music sounds like something from Limozeen haha. i haven't thought about doot doots or hey heys in a long time

I see a bunch of comments saying to add magnets but I’m not too sure that would work, you would need something to lower the CG and/or something to absorb the KE from high acceleration such as turning. I’m not too sure if it would work but creating a Z plane movement as well as springs or some form of resistance to reduce the acceleration of the can while moving.

Try adding some neoprene washers between the gyros. Your issue isn’t mass, it’s dampening oscillations. The neoprene washers should help slow down those unwanted oscillations.

You should add an inertia dampener like a set of magnets between the base and the holder, if you ever pick this project up again.

Okay the squares of plywood on the bottoms of the little bottles is God damn genius 🤙 idk how I got here but I'm definetly subbed 😂👌

Rocking the Alm Fab shirt! 👍🏽

you could have printed some of those parts sideways to use waaaayyy less support material

If it was me I'd probably be safer with the soda can controlling the one wheel, and putting myself in the gimble. :) Thanks for the video!

Run a bungie cord from the base of the cup to the fender mount? That could give it some play but restrict it from going upside-down.

you deserve 1,000,000,000 subs your a damm genius!!

Might work better if the can sits lower in relation to the pivot points and possibly add something to add a bit of friction or resistance so the pivots a little slower

The only way I see this working is a system like a stabilizing camera gimbal where the can never moved in orientation despite the angle of the wheel.

Maybe to help try putting springs on the stands like u said bc I think it’s possible that there’s a lot of kinetic energy that’s being absorbed and shaking the cup

Bro makes better content then the backyardscientist

You really needed before & after weights to quantify spillage. Most of the spillage is due to vertical shocks. And as you drink, the surface is farther from the hole, making it less susceptible to spillage. So, your shock absorber could be a simple elastic suspension, tuned to be most effective for the starting weight.

What if you were to switch th X and y access

if the pivot points were above the rim of the can it would be better . you would have to slot the sides to make sure you can pick the can out

big brain moment

It really needs some kind fo dampingso that the further it swings, the slower it goes. The bungee cord idea might be worth looking into

Fun to experiment, even if you didn't come up with the perfect solution....yet. ;)

Would be interesting to print one for large hydroflasks or make a fender with a storage built in for charger.

Awesome.

I don't have a one wheel, and don't think I ever will. I still loved the project though!

really need that z axis

That limit strap seems like it might work

I think adding resistance to movement would help... Like a shock absorber

Nice!!

Imagine a vehicle solely designed as a cup holder

Needs some springs and maybe weak dampers and it’s perfect

You need to include some sort of damping to stop the inertia of the large mass when it’s in motion. You’ve used Newton first law to help keep the cup at rest but you forgot that when it’s in motion it will stay in that motion and take longer to come to rest with a larger mass.

I need to have those 3d printers at home...

Lids. Plastic lids are already a thing for cans. Kind of a gimmick so you can save it for later without it going flat, but it would solve all your splashing problems and allow you to make it simpler.

Ideally the can shouldn't move at all. I think one possible problem could be too much friction at the pivot points transferring the motion from the gimbals to the cup.

I think one thing you didn't consider is the resonate frequency of the swing while you are riding.

this guy's really fun to watch, keep it up man, doesn't have to work for it to be entertaining, but just for the sake of it, what if the pivot point was way ABOVE the actual body of the can? would that no make for a more stable grip? I mean a taller holder, in which the can goes deeper, might be tricky to design in such a way that extracting the can from the contraption won't be too much toruble, but that aside it would (i imagine) work

My man said... Wa-La.... XD oh boy.

I think the magnet and bunjee woulda worked wonders. Or even just a string that wouldn’t allow it to go past 90°

Too much resistance on the pivots, using bearings or some kind of lubricant will keep it from catching and swinging
