There are plenty of Arduino instructables on here which will explain how to wire these up better than I can, so check them out if you're having any troubles. Whilst this works, [Hari] thought he could do a bit better, using butt-jointed PCBs as the frame material.

If everything's good, the dodecahedron should begin cycling effects (make sure your are using the wall adapter for power). To that end, I designed the base corner PCB, which splits the power between three separate connections. Once you are happy with your test fit, separate the face trios and apply glue to all of the exposed bracket edges.This process repeats all the way around the dodecahedron, at the end of the data loop only connect the power terminals, the data terminal doesn’t need a connection. I have provided a schematic for the data line and LED orientation for the dodecahedron, unfortunately, due to the laws of mathematics, dodecahedrons are ‘Non-Eularian’. Most people connect the strips with wires, but this quickly gets tedious, especially at smaller sizes. The data line is one single snake that runs in a specific pattern around the whole dodecahedron, and you have to follow the data direction of the LEDs (Most LED strips have arrows to show data direction). Since most of the dodecahedron is 3D printed, I thought it would be helpful to have a full exploded view on hand to make assembly more clear.

This matrix is used so that the code knows which strips are connected to each other in the LED loop, without this, a simple led running code will jump from one strip to another. This can be particularly annoying, because once you have to replace one LED, splicing in a new one might cause the one next to it to fail, and so you can get caught in a frustrating cycle. Keep in mind that anyone can view public collections - they may also appear in recommendations and other places. This is more easily done off of the dodecahedron because you'll need access to both sides of the PCB.Each JST-XH connector (they connect the base PCB to the controller) is rated to about 3A, so overall, they should be able to handle the current demands.

At this point the dodecahedron is all wired up, we will switch to building the controller before adding the finishing touches to the dodecahedron.On some sections, the arrows point away from where the next section begins, for example on edge 15 to 16. This LED Infinity Dodecahedron Trance Table Lamp is a unique hyper-dodecahedron lamp that is made to impress. The dodecahedron is made out of PCB with an inward-facing semi-transparent mirror film that creates an infinite number of reflections when looking from any angle. Make sure you do this in a clean dust free environment to avoid getting dust inside the shape, make sure to wipe down the mirrors carefully before installing them.

In the initial phase, we delve into your vision, shaping your ideas or crafting a concept inspired by our portfolio. If you think you require power injection (see step 2 for more info), you need 12 of these alternate struts to accommodate for this.

This took a few iterations to get right, fusion tells me my part is on "v54" but that's mostly because I was saving intermittently.
