Project Progress / Rebuilding the World's Largest K'nex Ball Machine
« on: March 08, 2018, 03:00:57 pm »
Hey everyone, I'm still alive!

My 140,000 piece K'nex ball machine at Brickmania is being disassembled to make room for expanded office space. The plus side of this is that my boss has decided to donate our entire K'nex collection to The Works Museum, where my other giant K'nex ball machine is located. Over the next few months, I will be modifying and adding onto The Works' machine with pieces from the Brickmania machine. I am hoping to hit a total of 200,000 pieces!

I've started a video blog to document this process, and as sort of a way to push myself to make my YouTube channel active again.

I'm actually about a month ahead of the video at the moment, and nearly all of the machine has been taken down, with the exception of the giant bridge. We just moved about 1/3 of the pieces over to The Works yesterday afternoon.

General Knex Discussion / 3D Printed Tan Clip Improvement
« on: September 09, 2017, 05:28:24 am »
One of the most frustrating things about building with k'nex is when a tan clip snaps off a rod because there was too much torque. This is especially irritating if it was deep inside a complex build.

I've been working on a solution to improve the strength of the tan clips using 3D printing, and I've come up with a design that snaps over a tan clip and rod.

With the addition of this small clip, the rod itself - even a black or tan rod - will snap in two before the improved tan clip ever gives way.

General Knex Discussion / Compact K'nex rod coupling
« on: September 01, 2017, 01:23:51 am »
I've been trying to come up with a way to couple two coaxial K'nex rods in the space between the 2 red connectors in these pictures. (10 blue spacers/one green rod wide).

So far, this is the best I've come up with. Has anyone else come up with other ideas, or do you have any suggestions for improvements on this design?

I have no idea what I'm doing.

Introduce Yourself / Hi everyone, I'm Austron

I just realized I never posted here, so Hello!
My name is Austin Granger. I go by Austron on YouTube, and just about everywhere else on the internet. I'm 25 years old, and have been building with K'nex since I was 4. I am currently working as a graphic designer / video producer for Brickmania, a company which produces custom Lego kits. I got into the K'nex ball machine scene in 2007 after I saw BuildFest's video Atomic Paraball. I built my own machine, Subatomic Paraball, as a tribute. I've been trying to out-do myself with each new machine again and again. Some of my other machines include Labyrinth (2010), Blue Fox (2011), and Clockwork (2012).

I have also built two professional installations. One for The Works Museum in Bloomington, MN, and one at Brickmania Toyworks in Minneapolis, MN, which is now in the Guinness Book of World Records as the World's Largest K'nex Ball Machine.

Apart from building ball machines, I also love experimenting with small mechanisms, especially transmissions. I've built automatic-reversing gear boxes, CVTs, and I am currently working on a 4-speed automatic transmission. I'll hopefully post my progress here.

Apart form K'nex, I tinker with programming and electronics, especially Arduino stuff. I also dabble in music composition, photography, 3D printing, and 3D animation / special effects.

My YouTube channel has been fairly inactive lately, as work has taken away a lot of my free time. My installation at Brickmania is still under construction, and I will hopefully have a final video of that done by the end of the year. Apart from that, I have a couple dozen projects going on at home at any given time, and I am notoriously awful at finishing any of them.

I plan to start being more active here, and I look forward to getting to know you guys and exchanging ideas!

General Knex Discussion / K'nex Geneva Mechanism
« on: April 24, 2016, 02:33:21 am »
I just finished this functional Geneva mechanism after a number of unsuccessful prototypes. I figured I'd post it, since I hadn't seen one of these built with K'nex without the use of 3D printed custom pieces.

This is just one small component of a very complicated mechanical project I have been working on for many months now. I will hopefully have a video up this summer, if I can actually make it work!
