Make Your Eyes Louder With Bluetooth Speaker Goggles

Posted on by

Your eyes are cool, but they aren’t very loud. You can remedy that with this build from [Sam Freeman]: a pair of Bluetooth speaker goggles. Combine a pair of old welders goggles with a Bluetooth receiver, a small amp and a couple of cheap speaker drivers and you’re well on your way to securing your own jet set radio future.

[Sam] found a set of speaker drivers that were the same size as the lenses of the goggles, as if they were designed for each other. They don’t do much for your vision, but they definitely look cool. [Sam] found …read more

Posted on by

Star Trek is often credited with helping spur the development of technologies we have today — the go-to example being cell phones. When a Star Trek April Fool’s product inspires a maker to build the real thing? Well, that seems par for the course. [MS3FGX] decided to make it so. The 3D printed Star Trek-themed phone dock acts as a Bluetooth speaker and white noise generator. The result is shown off in the video below and equals the special effects you expect to find on the silver screen.

Taking a few liberties from the product it’s based on — which …read more

Death To The 3.5mm Audio Jack, Long Live Wireless

Posted on by
