Mechanical vibrations course is one of the most difficult courses in most engineering departments. But you really did a great job man and I enjoyed your video.
I agree, designing and fabricating an anti-vibration camera mount is a challenge, I have constructed many over the last decade. The secret to success is "damping" not simply uncontrolled springs. Silicone and low durometer urethane are the best materials to use in a simple mount design.
congrats you found a thousand ways to make a springy camera mount :D dampening is key not springs. flex filament will give spring but no dampening. Springs are only there to hold a weight up or to flexibily fix it in a certain position. to make this "positioning" or "re-centering" complient you will be require to dampen any forces which is done with shock absorbers. you could try RC-car style ones or you go with some type of soft foam(hard to get hardnes right) you could design shock absorbers out of varioShore TPU as this gives springyness and dampening at the same time sort of. Dampening in general is done with converting motion to heat - so any form of, ideally variable, friction will get you somewhere.
Great video. I've tried building something from scratch, too. Haven't yet submitted it to practical use, though. However, one should consider that a vibration isolator must cover the vibration frequencies your setup is enduring and must cover for the weight and movement kinetics of your setup. The wider the spectrum of vibration frequencies and possible resonance, the more difficult it might become. One solution would be to have several stages, like the first one covering low frequencies and another one for the higher ones. Or maybe look how the brain is isolated from vibration inside the skull: liquid dampening and a billion of tiny elastic fibres, strong ones, weaker ones and so on. If you want to do some more serious testing, maybe get a small vibratory plate like they are used in chemistry and biology labs.
I think your final antivibration mount was dope. I think the main problem is really in the slider itself. You need to have a perfect track, perfect pully system, etc.. It's really hard for big companies to get right.
Some of those designs look decent but I think the issue is lack of damping. You've got springs absorbing vibration but transferring it straight back through their elasticity. You need something to absorb the energy. Try adding some soft sorbothane foam in the gaps and you might get to where you need to be
The issue is very clear, you're using a gear track to move it when you should be using a smooth rail system with motorized wheels and a break, it's bumping everytime the gears make contact.
I've been working on 3d printers for a while now, fixing them and designing them. The jerking of the rail system on your system could be a source of some of the vibration and the gear rack as well not meshing properly due to the camera weight, it looks like the system is trying to overcome a gear rack tooth at some points. Improvements could be a dual motor setup another motor on the opposite end, so it can push and pull not just push as it's doing now. Get better stepper motor drivers that can smooth out the jerk motion, and figure out how to adjust the meshing of the gear rack to compensate for the cameras weight. Keep up the good work and your designs are looking wicked cool so far!
Thanks for the input and you're absolutely right, it's shakey because the meshing between the rail stages are off, so every time it goes over a transition it's like hitting a speedbump, not to mention jerk from the camera weight. I've actually already rebuilt it with a belt system and a linear extrusion to have a much smoother glide, I was actually considering making an update video.
The problem is you have different tasks, which need different solutions. If you only have impulses as an input, so the camera (output position) needs to stay in rest,your decoupling concept isn't that bad. But if you want to move the whole thing, you dont need a full decoupling, but a good damping. Because some of the input (the translation) needs to be transferred to the output motion of the camera. There you need a different concept
You need PID tuning to reduce the inputs of vibration to the system. Futaba makes a green gel pad used for mounting Gryo's. Some of this incorporated in your system might be worth trying. We use the material to hold vibration sensitive sensors at work. Ultimately, reducing input the system is what's required.
Thanks for the work. The last one looks good. Try adding a small array of Nd magnets on top plate and copper sheet on the top of the bottom plate for eddy braking in the gap between the two plates.
good video and effort. But in this case all your issues were with the type of motor and gear ratio you used. As well, the track you used for the slider with the metal liner gear is for sure the main teeth of the monster you were restling with.
Thanx for the ideas, been thinking of making an anti-vibration mount for a bathroom fan in the attic. Oh and one more thing, you kind of look like James Franco...............ok thanks
I have a 3d printed shock design that would fit between the upper and lower plates putting it there would keep the system in tension or pre-loaded. It should help to stabilise the system a bit.
Hi mate, this might defeat the purpose of your experiment but weighting the receiving component of vibration has an inversely proportional relationship to vibration acceptance of the component. Also actually having a datum grid on the wall you are filming would be valuable data when adjusting the tilt, angle and position of componentry of your damping device. Could help you in your component material selection aswell. Adding preloaded compression and fiddling with rebound rates would be interesting to see
This right here about adding extra weight to the way to go. Try shooting on a moving cell phone to see how this effect is multiplied by the weight of a rig.
You need a solid surface to distribute the load and then a material that is slightly springy but more so dampening. Rubber is ok but foam is better. With that last design, having dense foam entirely under the rigid surface and then those spring loops on the outside might be the ticket.
The best way to eliminate vibration is to make something more rigid. You can do that by adding weight. Have you tried resting a concrete block on top of the camera?
not sure if you ever scrapped this or finished the anti vib mount,,but try some very light rubber bands or even springs ,foam in the corners at the bottom of the bird cage design to stop the swinging or even light foam ,bands etc at the CG of the mount to limit swing. just something to dampen it. Just some thoughts.
Use action camera or stabilization program, but this video is beneficial: I learned about shock mounts and how useless are they, please don’t throw them away, use them to test audio recorders and check which one is the best for absorbing shocks = unwanted audio, thank you for making this video 👍🏻
Also if you are so fixated on making camera sliders, 1-make 2 circler tracks on bigger than the other, put one inside the other 2-make another segment from compatible with each track in sizes then place each segment on top of the track parallel to each other then connect both segments together, 3- buy 4 bearings, 5- place the bearings inside the track, 6- attach the segment to the bearings, 7- attach electric motor to the segment and attach a wheel to it, is my idea clear, you can make a 360 product filming track 👍🏻
You need a big gap, and pointy design so the vibrate will spread to the egde of pointy design.. Like a compass( clock) but with more than 2 needles ( sun/star design )
Hi, Hilarious, very good video, I'm not as professional as you but I'm breaking my head on this too. The instability when walking etc drives me crazy. There are anti-shock systems for sale for $500 and are almost similar to what you showed in the beginning. I have given it op for now and seeing your vid I think for now the right thing. I will concentrate me now for kind of gimbal that are modular. But as I believe, there must be a way to find out how to made it real. I was able to laugh a bit when I saw your presentation.
I was trying to do something similar with my DSLR. The best I could do was to set it on top of a pillow with the camera sitting on a flat surface on top of the pillow.
Great vid! I found it searching for shock mount for zoom h6. And even though many of those mounts didn't fit your needs, don't you think it would be amazing as a shock mount for big audio recorder like zoom h6? It's shakey, so not suitable for camera, but looks like it should absorb all of the unwanted vibrations
Impressed with your design ability. Really cool stuff my friend. Please forgive me if I sound like a jerk but, can you post another video the same exact one as this without the the repetitive music-noise in the background? I know it's hard to think of everything when making a vedio. Best regards.♥️👍✌️
What about a tension frame? Think skeletal tubular cube with a center frame liked to the main cube with rubber bands. Think an old fasion suspended mirophone. Where the mic is suspended by springs or bands to cancel all vibration.
instead of gears, use rails and rubber wheels like a rollercoaster, i imagine that would help then if u use a servo motor maybe it would be pretty stable
DAMN it's look way more difficult as i though ... and also questioning the capability of those who can be find on market ... i think the overall aspect of the final video will need to be proceed by AI that get ride of vibration ... by croping a little bit your footage and that's something similar in the last iphone and gopro software system ... did you find anything better now ?
TAKE 30 AND FRESHEN UP ON AUTOMOBILE SUSPENSIONS. THERES A BUNCH OF CRAZY PHYSICS THAT DIRECT THE TOLERANCES OF SUSPENSION. RIGHT OFF THE RIP.....YOUR MISSING SOMETHING TO ABSORB THE VIBRATION. LIKE FOAM, SPRINGS AND SOFT RUBBER HELP DAMPENING TO.
good job. i felt like you were limiting yourself using only 3d printed stuff. the cables were good. in that final design, i was thinking a bladder of viscous liquid between the platforms or a sheet of silicon or ballistics gel. learn anything new since? mag lev?
Thank you for your idea's. I'm currently cobbing together high powered fans to cool my sim wheel motor. I have a thrustmaster t300 sim wheel. It's a belt & pulley system powered by an offset motor that's sheathed in an aluminum heatsink for cooling. To aid in cooling is a 60x10mm China crap fan that's not only 4" away....it's pointing the wrong way as to exhaust. It's a shit design..
In this video your voice is a little too quiet while your audio queues and music is too loud. Might want to get a lav mic or put your mic a little closer to you, or mix your video's audio differently.
Mechanical vibrations course is one of the most difficult courses in most engineering departments. But you really did a great job man and I enjoyed your video.
I ended up taking 3 vibrations courses at once my senior year 😅

I agree completely, I think that's the secret sauce of creating any anti-vibration mount that works effectively.
The issue is very clear, you're using a gear track to move it when you should be using a smooth rail system with motorized wheels and a break, it's bumping everytime the gears make contact.
Exactly. There are affordable rail+ sledge solutions available. Using rubber belt drive might be a little better also.

I have the same issue now to figure out how to remove small vibration on my DIY camera stabilizer. Big thumb up for your hustle!

i've spent a ton of time and money working on this problem and it's been the bane of my existence.

Most relatable video I’ve ever seen on the RUclips

dude.... I am going through the same thing .... vibration is just a little .... but thinking about using rubberbands
not sure if you ever scrapped this or finished the anti vib mount,,but try some very light rubber bands or even springs ,foam in the corners at the bottom of the bird cage design to stop the swinging or even light foam ,bands etc at the CG of the mount to limit swing. just something to dampen it.

Thank you, I appreciate it
The two states of a 3D printer:
- Why won't it stick to the bed..?
- Why can't I get this damn thing off the bed?!
Excellent demonstration of all sorts of things that don't work :) very helpful! (serious)
Also if you are so fixated on making camera sliders, 1-make 2 circler tracks on bigger than the other, put one inside the other 2-make another segment from compatible with each track in sizes then place each segment on top of the track parallel to each other then connect both segments together, 3- buy 4 bearings, 5- place the bearings inside the track, 6- attach the segment to the bearings, 7- attach electric motor to the segment and attach a wheel to it, is my idea clear, you can make a 360 product filming track 👍🏻
Sorry for the spelling mistakes, 1- one bigger 2-make another segments compatible (without from)
