Use the Force to Turn On This Lamp

Holocrons are holographic data storage devices used in the Star Wars universe by both Jedi and Sith as teaching devices or for storing valuable information. After the fall of the Jedi, they became rare and closely guarded artifacts. [DaveClarke] built one to light the room.

[DaveClarke] built the lamp around a Particle Photon – a STM32 ARM-M0 based microcontroller with a Cypress wifi chip. All [Dave] needed for the workings were an IR proximity sensor, a servo and a bunch of super-bright white LEDs. When the sensor detects something, it starts up the system. The servo rotates a gear which raises the lamp and fades in the LEDs. The next time the sensor detects something, the servo lowers the lamp and the lights begin to fade out. And since the Photon is connected to the cloud, the system can be accessed with a web interface as well.

Okay, so it’s just an IR sensor detecting reflected infrared light and not the Force that’s used to turn it on, but it’s still pretty cool. There are plenty of pictures and videos at [DaveClarke]’s site, along with a schematic, 3D printer designs, and the source code. The whole thing was designed using Autodesk Fusion 360 and 3D printed in about 30 hours and press-fits together. A very simple yet clever design. There have been some other great lamps on the site, like this blossoming flower lamp or this laser cut lamp with which also has a unique switch.
