LCD Glasses #3DThursday #3DPrinting

In this week’s project, we’ll show you how to build pair of electronic sunglasses. These are really cool because you can actually control the dark tint from the glass.

Sandwiched in between two sheets of glass is a layer of liquid crystal material. When voltage is applied to the electrodes, it turns dark and filters out bright light. Depending on how much voltage is applied, you can control the tint or opaqueness of the glass.

This is a Liquid Crystal Light Valve (a.k.a a LCD Controllable Blackout Panel) and they’re mainly used in welding helmets because it can protecting your eyes from really bright sparks.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
