Summary

Edit: 2/24/2022 - Added a bit more details and tips for getting things situated and connected as well as added a new base version with a momentary press switch (button) and URL to see which button i used.

Decided to make my own LED Light Assembly. So many i've tried have pieces that are so thin and fragile, i wanted to make something with a bit more substance. All assembled, the fixture comes in at 6.236oz. The base is blocky but i printed it hollowed out with internal supports and with the Siraya Tech Smoky Black resin i used, it looks amazing and almost carbon fiber like! I'm quite pleased with the outcome of this!

The Lid has 1.5mm thick walls and the Difference from the inner walls of the lid and the outer walls of the base is 1mm, so it is plenty snug without being over the top loose. The top is thick enough where you can use an orbital sander on it (i worked my way up to 1000 grit) for a nice surface and then i spray painted it with krylon matte finish clear coat. I updated the version of the base and lid STL files from what is pictured above, Very minor and not worth re-printing it to me, but I adjusted the USB opening so its a bit easier to plug the USB into it.

Parts List:

ESP8266 Card: https://www.amazon.com/gp/product/B081CSJV2V/
8x8 Matrix LED: https://www.amazon.com/gp/product/B08QN1XDWG/
Jumper Wires: https://www.amazon.com/Elegoo-EL-CP-004-Multicolored-Breadboard-arduino/dp/B01EV70C78
Wire Shrink Wrap Tubing: https://www.amazon.com/650pcs-Shrink-Tubing-innhom-Approved/dp/B07WWWPR2X
Momentary Press Switch: https://www.amazon.com/dp/B075LDGHHS?psc=1&smid=A2NNH5C5IP9N3O

So you can make this happen without soldering and without programming knowledge. I did and i have none!

I Cut off the Output wires from the 8x8 grid array, and then used that pigtail i had just removed, stripped off the ends. i then took a couple of my female jumper wires and cut them off and stripped off those ends. I then twisted the 5v wires together, the ground wires together and then the signal wires together, then i tinned the joint (put solder on) and covered them with the shrink tubing, but you definitely don't need to do the soldering part. You can now simply slide the pins onto your ESP8266 and you're good to go!

I wired up the female jumpers to the LED pigtail outside of the case, doing it this way makes getting them in their positions kind of tricky. bend the wire to help angle the female jumper tip up, underneath the opening for the ESP8266 pins, I then have to work it up in that space using a tweezers. Once i have all 3 pushed into their positions i push the jumpers on the appropriate pins and then push the ESP8266 down into its spot. Its a nice and snug fit, such that you dont need to screw in the chip and it sits there perfectly. The other way you could do this, is to slide the clipped end of the jumper down that same pin hole and then connect to the pigtail with those tips already up there. Its just tough connecting the wires in a tight space, its doable and there is room to tuck the wires in the base though so do whatever you find easiest.

As far as the pin outs, You plug green into D4, Power into the 5v and Ground into any grounded port, the url i referenced has nice pictures to help with that.

As far as the ESP8266, i used this tutorial:
https://tynick.com/blog/11-03-2019/getting-started-with-wled-on-esp8266/

It walks you through installing NodeMCU PyFlasher ( https://github.com/marcelstoer/nodemcu-pyflasher ) which is the program used in this tutorial to load the simple web server and Wifi LED functions.

Then you head to the releases section and download the latest version. This will be a bin file ( https://github.com/Aircoookie/WLED/releases )

You then select your plugged in device from the Serial port drop down, select the bin file in the firmware box that you just downloaded and click the flash button.

After this happens, the device will reboot with the server loaded on it, it will be broadcasting its own WiFi network of "WLED-AP" with password of "wled1234"

Once you connect to that wireless AP, you will get to a screen where you can enter in your own Wifi Settings where it will once again reboot and you can set your phone or whatever device you used to connect with back on your home network. You need to figure out the IP address your router assigned this device but once you get that, you simply go to http://yourIPaddress and you can start adjusting things.

Tip, When you first connect the matrix LED array, it will only partially light up orange as the default color is orange when flashed, and its programmed to use 32 lights. you need to go to config and then LED preferences and tell it that you have 64 LED's, else it will only light up the first 30 lights as that is its default setting.

Overall i'm quite pleased with how the light turned out and i think the Siraya Tech Smoky Black looks incredible. Its a fun and relatively easy project, give it a shot!
