How did I look at this thumbnail + title and instantly think "that's a Henry Segerman video" 😂 Mans got a style

These demos remind me of the Hoberman Sphere - that spiky ball toy that expands and contracts through a bunch of linked scissor mechanisms. The Hoberman Sphere is recursive too, except there the components have a network of relationships rather than just a chain of relationships.

I'm just shocked how damn smooth that contraption works 😲😲😲

I really want to see a machinist like This Old Tony make some of these and see if he can come up with a practical function for them, like perhaps for shelving or something.

You really do explore some wondrous mechanisms that are very mesmerizing to watch in motion! Thanks for all your brain scratching displays!

i would love to see a video about your process for creating mechanisms like this! do you use any programs or simulations when you're throwing ideas around? maybe we could see some early prototypes of some of your projects?

I always love the mechanisms that you come up with. It just got way better, now that I realized I also have a 3D printer!

Satisfying yet functioning and incredibly fast-responsive mechanism. Nice extra details from prior projects you had included in this video.

One of the best ideas I ever seen! So smart, so simple, so mechanic!

i love the no bs intro. 7s of displaying something really cool then on to explaining it.

Seeing how the original worked, and then seeing the second one, I was actually pretty happy with myself for being able to work out how the second one would work relatively quickly. That being said, once you did confirm it, I immediately thought of trying to find a way to use these and other slightly modified racks to act as logic gates. Would be very interesting.

Spooky action at a distance indeed 🔥

Shapeways is going to lose a lot of business now that Henry has developed the ability to magically bring parts into existence by simply pointing his finger. 😉

How you managed to get the action so incredibly smooth on 3D printed parts is simply beyond me

I swear, this will be how certain meta-materials will work some day when we can get consistent "gears" made of bio-mechanical components/layers. I imagine this could be a great mechanism for frequency combing.

Just wonderful - this is as beautiful as it is functional. Thank you for sharing!

Love the video! If you take the first design, add a pin to the center box (attaching it to the surface below it), add another pin to the end of the left most gear rack, and a marker to the end of the right most gear rack. You will get a drawing copy machine! Love it!

Henry Segerman videos never disappoint

This reminds me of K'NEX and ERECTOR sets. Many fun times as a kid.

As somebody who prints and unpowders alot of your models its always great when I see them come through! Would it be possible to make a cube with recursive racks? Some thing like a Hoberman sphere or similar.
