This is somewhat visible from the product image, and I just didn't look too closely, which is on me. The easiest way to add the buttons would probably be to use a triple button breakout board that I've designed here.

This may be easier to keep track of, but due to tolerance issues, soldering all the connections to the PCBs may be more tricky. The frame has small built in tunnels which can be used to run a data line back under an LED strip to continue with the data path you can see where these jumps are needed in the reference layout graph. We want the DC jack to be center positive, which means that the positive line is connected to the central pole inside the jack.Prioritizing ease of maintenance and durability, we design our luminous artworks to withstand the test of time.

One-way mirrored film usually has a protective plastic layer on the adhesive side so you will need to remove this (also under water) before placing the film on top of the acrylic sheet. I have a bit of an obsession with regular dodecahedrons in general and of course the Roman dodecahedrons are especially interesting and mysterious. This is okay with the mirrored sides because you can use acetone to dissolve and wipe away the epoxy. We, in our turn, can repair your product, but dispatch and repair may take a long time, which may not match your deadlines. The final step of this intractable is to install the mirrors into the frame of our LED dodecahedron.

If everything's good, the dodecahedron should begin cycling effects (make sure your are using the wall adapter for power). The main advantage over an Arduino is being able to switch animations on my phone over wifi instead of uploading new code to the microcontroller. If you remove the mirrors and LEDs, then you’re just left with a plain old dodecahedron, like this cool folding project .

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. Each edge section holds seven LEDs, so by using the numbers you can determine which set of LEDs is on that edge. You will also need to connect the ground for the Arduino to the same ground terminal to avoid shorting.Although you are unlikely to ever run the strip at full brightness (and heat buildup would probably limit the current draw anyway), I wanted to do my best to accommodate it. 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). To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. I recommend inserting the trio with brackets all around the outside last because it has more places to safely grab than the others.
