Yeah, eventually I'll port my code, but until then Esp8266's seem to work best. It's not too bad tho, you do miss out on the built-in Bluetooth and dual core capabilities of the Esp32, but overall, both processors have plenty of memory and speed to drive most led setups.

I designed these independently. I remember seeing some shades (which were almost certainly an early Macetech prototype) at a Makerfaire a number of years ago, and the idea got stuck in my head. I didn't have the skills to make my own at the time, but eventually I came back around to the project :)

Good things to know, and it's nice to see an alternate design. It's true that flexing the mask a lot will damage the wiring eventually, but if you pre-bend the mask so it fits your face, it should minimize any flexing. Likewise, the mask should be handled with some delicacy. As for the battery, I was thinking of mounting it with the controller on the large rear strap. This should take the strain off the elastic, as the rear strap is supported by your head when worn. I'll update the design asap.
Not specifically, but I did do an image search for led masks to help brainstorm when first developing this project, so maybe it popped up. I don't really remember haha.

Sounds like it could be a logic level issue. You can fix it fairly easily by using a SN74AHCT125 to convert the esp8266's 3v3 signal to 5v for the Leds. Alternatively, you can cheat with a signal diode as described here: https://hackaday.com/2017/01/20/cheating-at-5v-ws2812-control-to-use-a-3-3v-data-line/. Both methods will require some re-wiring.

It's seems to be fine for me, it's the gerber zip file attached to the supplies step. You can also find it (and all the other project data) here: https://github.com/AlbertGBarber/Digital-Multi-Tool

Good to know. You definitly cannot with my mask haha.
LED foam (plastazote) is different from normal EVA foam. It is significantly less dense, and allows more light through. I used LED foam mainly because I already have a bunch, and it works well. It's difficult to get directly in the US, but I have found one US seller, which I've linked to in the supplies list. That being said, you can definitely use other materials as a diffuser, so I encourage you to experiment.
You can't really do a super intensive cleaning unfortunately. You can lightly soak the back fabric with soapy water, but be sure to disconnect the controller first and wait until the mask is thoroughly dry before reconnecting everything. You could also disinfect it with UV light. If you'd like the wear the mask a lot, I'd suggest wearing a regular cloth mask underneath, to catch/absorb moisture.
Good luck! Btw, if you do go with an ESP32, be sure to test it with the LEDs before putting everything together. Since the ESP32 is newer, it's support is a bit more patchy than the ESP8266, and I've had them produce visual glitches when driving ws2812b leds. I think this is fixed when using the FastLed library, but I've been using the Adafruit one for a while, and have not had the time to port my code over.
It's difficult to give a definitive total cost. If you're starting from absolute scratch (no tools), and you want the parts as fast as possible the total will probably be in the $200-300 range. Buuuut I would expect most people to have some of the tools/parts. If you have most of the tools, and are willing to buy the electronic parts cheaply and wait on shipping, the main costs are the PCBs, mask, Leds and the LiPo. These could cost you as little as ~$60.
You could definitely put the LEDs on the front instead. Not sure if you'd fit a huge amount more, maybe one or two more strips in the middle. Overall, I put the LEDs inside the mask because I thought it looked more ascetically pleasing, and the outer mesh protects the LEDs/diffuser.
There's a link to the mask in the "other parts" section of the supplies list.
Haha that would be fun to add, maybe someday......
Thank you, my code might not be the easiest to go through, but you're welcome to try :)
Each Led can consume a maximum of 60ma at full brightness, so that would be 6A total dissipation for the mask. However, in reality their consumption is much much lower; my code doesn't allow you to go to full brightness, and generally, most animations don't use full white. Overall, the mask doesn't get noticeably hot, and it isn't any more uncomfortable to wear than a normal mask.

Yep, if you've ever worn shutter-shades, it's pretty much like those.
Thank you, btw I really like your LED Christmas tree :)

Yeah, it is quite a lot. I should have added that the cost of the PCBs (with assembly for the shades PCB) is ~$50 if you get them from JLC. So the remaining $100 is just for other supplies, but it's pretty likely you might have some of them already (heat shrink, a spare key-ring ring, M2 screws, etc) so your actual costs could be a lot lower.
If you buy everything using the links I provide it'll cost ~$150 USD before shipping (sans tools). Keep in mind this will be enough to make 5 shades (you'll get at least 5 PCBs due to order minimums), including 5 copies of the Digikey BOM. I only included one power bank in the total, so if you want one for each of the shades add ~$40.You can save ~$30 if you assemble the Shades PCBs yourself. You can probably find most of the parts for cheaper on sites like Ebay, Alixepress, Banggood, etc.
