These days, there’s all manner of addressable LEDs out there that can be easily used to produce blinky, flashy projects. However, there’s nothing stopping makers from doing things the old fashioned way, and hacking together an matrix out of raw LEDs. [Deepak Khatri] did just that with his own custom build.
Rather than rely on a PCB or other substrate to hold the matrix together, [Deepak] elected to freeform the design instead. A matrix of holes was cut in a cardboard template with the aid of graph paper. LEDs were then inserted into the holes in the requisite pattern, and their own leads soldered together to create the frame for the glasses. Additional wires that were needed were then installed, doubling as a bridge to allow the glasses to rest comfortably on the nose. Black epoxy was then used on the back side to block the light from blinding the wearer. The matrix is controlled by a pair of shift registers addressed by a microcontroller, and the display animates impressively smoothly.
it’s a fun build, and one that we suspect looks particularly impressive at night. They’d also make it easy for your friends to spot you in a dark club. We’ve seen some impressively stylish LED glasses over the years, too, dating all the way back to [macetech]’s pair from 2012. Video after the break.
