Keep the flux going!

Welcome to Knex Flux!

Welcome to Knex Flux, a new kind of knex community, where both instructions and forum are integrated into the same site.

We are here to unite all of the knex community under one website, the forum giving you space for discussion and the instructions to share your projects.

K'nex Plate Wheel Lift
--> View Instruction

Hey y'all

This is a very simple but good looking wheel lift that I used in my ball machine 'Emotion'
The construction is very simple, doesn't require a lot of pieces, and works with other types of motors too. The balls get raised by 3 blue rods, or 1.5 red rods.

If you have any questions, as always, let me know.

Interior Trusswork
--> View Model

This is a new and different method of reinforcing cubic towers with trusses. Instead of the four sides being filled with trusses, the truss beams cross through the center, and the two perpendicular beams intersect in the very center to form a plus shape (when viewing from above). Unless you have a large supply of orange peg clips, this can only be assembled using blue 3D connectors in the center. If there were white rods running horizontally between the yellow connectors, equilateral triangles would be formed, but that requires many peg clips.

At the top of the truss section, the white rods should be angled outward in all directions, and an X can be added. This requires 6 peg clips if you are alternating in a checkerboard pattern between gray 3D connectors and red connectors along the vertical running corners of the tower. As long as all four connectors on the top and bottom edges are gray 3D connectors, the tower cannot lengthen and shorten from rods sliding through the red connectors.

With exterior truss, even if there are available blue rods between X units, adding a solid connector railing requires a blue rod to clip onto at every green unit, and connectors cannot clip onto a green rod beside a white connector. Interior trusses retain robust structural strength while allowing there to be blue rods on every single horizon. The trusses do connect to the edges by looping yellow connectors through the blue rods, but that does not interfere with adding railing unless there will be less than 1 connector-width (6mm) between the rails.

Instructions will be coming soon (hopefully).

Small-size Mass Damper
--> View Instruction

First off, I apologize for publishing the second consecutive instruction. Please, someone besides me, publish something. Anyways, this is a small-sized mass damper weight that swings around at the top of a tower. Mass dampers respond to vibration and reduce the movement and swaying of tall structures. It is ideal for towers that are the size of a blue square.

The weight is partially surrounded by a slick 37mm tire. The upper 2 white connectors have 2 Y-clips on each side that hold the tips of 2 white rods, one on each side. The length of the suspending rods can be varied to adjust the frequency, but a single white rod is the shortest length. The mass unit can swing in all directions, similar to a universal joint.

This design can be extremely beneficial, useless, or somewhat harmful depending on the frequency and amplitude of vibration. It is most effective for high frequency vibrations with small amplitudes. Lower frequency and/or larger vibrations may cause the mass unit to collide with the tower frame (because my designs are always poor designs).

When paired with base isolation (which I will be more motivated to publish if someone else publishes something), mass dampers can be used to simulate higher masses (more inertia and resistance to movement) on the base isolation springs without substantially increasing the weight load (less gravitational force to overload the springs).

Rod-Gear Interlocking System without Tan Clips
--> View Instruction

This is a rod to gear interlocking assembly that does not use any tan clips. I was experimenting with using splice clips and an orange connector to try to make an improved gear coupler that does not clamp to the rod and spaced the gears further apart, but I ended up developing this that does clamp the rod. The splice clips protrude into the orange connector, and the orange connector is clipped to white rods that hold purple connectors clipping into the metallic gold yellow rod. The tips of the white rods would not fit until the splice clips were angled to the side.

When twisting the purple connectors directly, it is extremely tough and unbreakable. However, when twisting the gold rod with orange connectors clipped to it, the assembly breaks apart under slightly more force than a tan clip can tolerate before detaching. This can be solved by using blue rods in place of the white rods and clipping more purple clips to the gold rod, but even with the white rods this assembly would require a wide chamber compared to a tan clip, like a blue unit wide instead of a green unit. Also, the crown gear must be facing towards the assembly, and if a crown gear needs to be facing away then another gear must be coupled adding unacceptable complexity and width (unless you 3D print a gear with the center area extended on both sides). The interlocking assembly has much more slack than a tan clip.

YSL's 6-way Ball Separator
--> View Instruction

This instructions page will show you how to build my 6-way ball separator. The ball separator consists of a manifold, 3 blue rods deep by 4 blue rods wide by 5 blue rods tall, which rotates back and forth as it separates balls evenly between 6 outputs. While this design certainly isn't the most space-efficient method of separating balls, it does provide a nice visual element as it pendulates back and forth. This ball separator was designed and tested with standard red/yellow K'nex balls, so I cannot tell whether this will or won't work with the oversized/underweight balls from the Big Air Ball Tower. If you want to see if this will fit your machine before building it, mounting instructions are located in Step 6.
