I wanted to try something a bit silly with a light box, so I had a picture of my sister's cat wearing a tie drawn up and then converted it in to a light box.

This was not done by use of some vectorization service, but by hand with a stylus.

I played around with it in Fusion until I was happy with it, having a separate zone for the tie and standoffs to support a D1 Mini v3 and an AOD4184 module. They secure in using some little screws from a kit of self-tapping screws, I believe it was two M2.7 for the D1 Mini and two M1.7 screws for the AOD module. There are also two recessed holes along the edge of the print that hold together with two M1.7x5 screws, as I properly guessed friction-fitting these thin walls was not going to work. You could substitute adhesive - like E6000 - if you wanted, but I don't like gluing my boxes together.

I created flush-mounts for a power switch and USB-C snap-in to control power to it. Had a lot of questions about that so I made a video on how to do it 😂

Prints with three colors on the face - black, white, and clear (for the walls). Uses two for the base, black and silver. I used eSun black, warm white, metallic silver, and FilaCube Natural HT-PLA+ for the clear. The first three layers of the face print in black and white, with the remainder printing in clear. I did have a pinhole or two, but they are small and hide away well enough for me to not want to open this monster of a drawing back up.

Wiring isn't that bad in the end. The goal was independent zone lighting using a COB LED strip for the majority of the box, but a WS281x LED strip for a color accent. This presents a challenge as there's no PWM controller capable of handling 5V (let alone the wattage) necessary to drive an LED strip on a D1/ESP32. That's where the AOD4184 comes in. Given a signal wire from the D1 Mini v3, it'll convert whatever voltage I throw at it to a PWM-controlled source that would allow me to have both a WS2812B and a PWM COB LED in the same box, on the same power source, with dimming/power control.

I used a leftover four-SMD segment off a WS2812B strip and carefully threaded some wires through the little mousehole (it's tight). The ends kinda bent up a little bit but I pushed it down from the middle-out and it seated just fine. An ultra-narrow strip could let you put two side-by-side if you really wanted to, but I think the light output from four 5050's was sufficient. Of course as always I strongly suggest you use an alcohol prep pad to wipe your print down before affixing LED strips to ensure a strong bond, and I also don't use the dirt-cheapest strips to begin with - strips with genuine 3M adhesive bond just fine and stay in place.

Wired it up as follows:

Things to note:

• use of a common VCC (+5V)
• use of a common GND (-5V)
• the GND connection between the input and output of the AOD is bridged
• the WS2812B strip is driven off GPIO1 (TX)
• the AOD is driven off GPIO5 (D1)
• the COB LED takes it's GND from the middle pin of the output of the AOD, not common ground!

Configs for the D1 Mini are attached in documentation. Flash your D1 and import at least the presets, but probably the config as well. You might have to re-write it's SSID configuration, not 100% to be honest. It should broadcast an SSID “vegas-tie” for you to connect to if necessary, if it does the PSK is 0123456789 (although I don't think that's saved in these configuration exports).

In any event, here's how I had it configured at the end of the day:
