If I were to start building something, and want to post my progress without instructions, I'd post it in one of the following:
  • Project Ideas and Help if I want ideas for my project
  • Project Progress if I want to brag

As you probably know, there are tan rods (red rod size) and black rods (grey rod size) which are stronger than their normal size piece.

I don't completely understand your question, but Austron has developed an automatic variable transmission gearbox that changes speed depending on torque.

Was it difficult modifying the red battery motors or did you put something like a alligator clips on it?

I use battery powered motors. Over time the batteries run out of power and the motor slows down and looses power. Then I recharge the batteries and the motor goes back to full speed and full power.

Are there any similar problems when using the motors that plug into the wall?

On the topic of motors, does anyone have a good use for the spring motor?

Yes the 'width=x' thing works.  :)

Thanks for the patches!  ;D

Most of the user-friendly-ness issues originated from the bugs, which are now solved.
It there a way for me to resize a Youtube video in a post?

In my opinion Knex better for building contraptions and things with moving parts than other construction toys (such as Lego), but is more difficult to build recognisable objects. You can't really build a solid wall (or many clear unicolour shapes) in Knex, so branding doesn't quite fit with Knex.
On the other hand, cyber Knex can achieve impressive things when considering it is a toy. I've never used it but it would be cool to try it, and I think it has quite a potential.

I suppose my opinion is very bias as I only build ball machines and similar contraptions.

As far as promotion goes, I think Austron did a great job at the Works Museum back in 2013 to promote Knex and specifically Ball Machines. (This one: https://youtu.be/KJhoIfiHjVE)

I want to build a robot out of knex using only one motor.

I am able to get the robot to swap tasks with this type of gearbox: https://youtu.be/WlGI07xRFuI

The problem is, I don't know what I want to get the robot to do. Any Ideas?

It would have to be a looped task (the robot ends where it started) and I would like it to look similar to a human because my friend believes I can build sentient knex machines,
which I can.

The 'new topic' button is unavailable in most forum categories (eg Project Ideas and Help) it's just not there. I can only reply to posts and introduce myself.
Also, I'm receiving error 500 when trying to set my avatar.

Personally I believe this website could be made much more user friendly for new users. I am struggling to find my way around.

Project Progress / Re: The start of each building...
« on: October 17, 2015, 11:32:10 am »
I always keep my pieces sorted. I have about 3000.

I have small (3L) containers of each type of regular piece categorised by type (rod/connector) and size. All the containers fit in a larger box. Pieces such as wheels, gears, motors, tubes, etc are in random unordered box.
Whenever I need a piece, I know where it is, and take it from its bucket. When I deconstruct, I return each piece to its container as I take parts apart.

This process probably doubles the amount of time to deconstruct machines but it makes building so much more enjoyable and convenient.

Hi, my name is Jake. I am 17 years old and live in Australia and have build building ball machines since 2009, but knex since 2005.
I was Knex Fan of the Month in April 2015, see http://www.knex.com/photos-and-videos/fan-of-the-month/2015/April-Jake/

I mainly build ball machines but I also like building gearboxes which I then use for my ball machines. My ball machines are usually slow, small, compact, and complex.
I try to build at least two new elements in each of my ball machines, but usually these contain large mechanisms that crowd the ball machine and make the track less visible.

I have tried making perpetual motion machines out of Knex. I did not succeed (obviously) but it inspired me to build lift/element hybrids, such as my favourite element, the weighted kick. (http://www.instructables.com/id/Knex-Weighted-kick-ball-machine-liftelement-hybrid/)
