Oh why hello there! It is finally time for me to share my Adafruit Neopixel Visors that I have been working on for some time. I create two different pairs of Neopixel visors in two different styles, both gifts for two different Twitch Streamers, FuturemanGaming and BadBadRobot. I’ve got all the details you need, whether you’re just a fan of my projects, or a fellow nerd looking to build some Geekmatic visors!

First, let me show you a few pictures of the finished product.

Now that you have seen them all done and proper, lets go over what I used for this project. I build three visors total, so all of the parts below are multiplied by three. All parts were purchased on Adafruit:

  1. ZeroUV Futuristic Retro Mirror – $9.99 or ZeroUV Retro Futuristic Novelty Space Cadet – $9.99
  2. Adafruit Gemma v2 – $9.99
  3. Adafruit NeoPixel RGB 144 LED Strip – $59.99
  4. Lithium Ion Polymer battery – 3.7v 350mAh – $6.95
  5. USB Lilon/LiPoly Charger v1.2 – $12.50
  6. Mini Solder Spool 60/40 0.031″ 100g – $7.95

Tools that I used:

  1. Soldering Iron
  2. X-Acto Knife
  3. Adafruit Flush Diagonal Cutters – $7.25
  4. Adafruit Hakko Professional Quality 20-30 AWG Wire Strippers – $11.95
  5. Hot Glue Gun
  6. Professional Gaffers Tape
  7. Scotch Transparent Tape

I already had a good amount of red, green and black 22 AWG Solid Corewire on hand, so I did not list that. You will also need some solder flux if you are planning on building something similar to this.

So the first thing that i needed to do was test fit all of the parts on the visors themself. I took the waterproofing silicone off of the LED stip, snipped the ends, and counted out 19 LED’s and cut that off. 19 LED’s was the most I could fit on the visor without going over. As you can see in this picture below, I originally started this project with the Trinket, because it was smaller. But, using the Trinket meant that there was no On/Off switch on the board itself, and I could have to solder the battery to the middle of the LED strip, which I wanted to avoid. The Gemma has a on/off switch on the boar itself, and also has a JST connector for the battery. This way, I could unplug the battery and plug it into a charger easily.

Once I test fit everything on the visor, it was time to start snipping the solid core wire, and soldering them to the LED controller.

And with everything soldered, it was time to mount this stuff to the visors! Couple things to note here:

  • On the back of the LED strip, be sure to lay down a layer of Scotch Transparent tape, so that no skin will come in contact with any of the leads. We don’t want you getting shocked!
  • Originally, the LED strip was held down with Gaffers tape. But, once I got the placement and sizing down, everything was secured with hot glue.

I will show you how the FuturemanGaming visor looked first.

And then here is the the BadBadRobot visor next.

And here are the finished products! Below you can find a few GIF’s of the visors in action.

And that is that! Hope you guys enjoyed this!
