Shutter shades were cool once upon a time, but if you really want to stand out, it’s hard to go past aggressively bright LEDs right in the middle of your face. A great way to achieve that is by building a pair of RGB glasses, as [Arnov Sharma] did.
The design intelligently makes use of PCBs to form the entire structure of the glasses. One PCB makes up the left arm of the glasses, carrying an ESP12F microcontroller and the requisite support circuitry. It’s fitted to the front PCB through a slot, and soldered in place. The V+, GND, and DATA connections for the WS2812B LEDs also serve as the mechanical connection. The right arm of the glasses is held on in the same way, being the same as the left arm PCB but simply left unpopulated. A little glue is also used to stiffen up the connection.
It’s a tidy build, and one that can be easily controlled from a smartphone as the ESP12F runs a basic webserver which allows the color of the glasses to be changed. It’s not the first time we’ve seen a flashy pair of LED shades either! Video after the break.
For an even stronger PCB-to-PCB solder joint, use plated through slots instead of pads placed on the edge of a non-plated slot. At least JLCPCB can do up to 6 mm long plated slots, which would fit 5mm wide tabs of the other PCB tightly. Plain pads (even with vias) tear off PCB surface much more easily than through-plated ones.
will do that in next version, thanks for this useful tip!
Could even mill in locking tabs, clip tenon joint.
The only value of posting such a stupid and uninteresting project lies in possible great comments like theís one ↑
Yes, yes, it pales in comparison to all your offerings.
I have an eight-year career of getting LED glasses on Hackaday, it’s good to see new blood to carry the torch of the most useless of blinky devices long after I’m gone someday.
