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.
I’m in agreement with [starhawk] this time; 20 MB crappie GIF, delete it.
Next time I will use the tip line, sorry.

hackaday, where using a 20MB gif as a title image is normal
indeed, this one is no exception. And despite all negative comments each time they do this, they keep putting them online… Therefore I wonder how long it takes before youtube decides to present all their videos in the “superior” GIF format, because it just has to be the better format otherwise why would hackaday use them so much (they must be knowing that it always results in lot’s of negative comments).
If there is a slogan competition then I would like to suggest: “Hackaday… the website that cares about what their readers think” because I’m sure that in the future they will come to their senses and stop wasting internet bandwidth and resources.
How much more work and resources would it take to make you the only force user, i.e. a wireless wearable with gesture/brainwave sensing?
The GIF. Fixed.
Sorry [Rich Hawkes], but this is the majority of the reason your article failed. Live and learn. At least it wasn’t a 40+ MB GIF of a swinging gate…
I have several LED lamps that sense movement, saves on batteries for sure. Been considering those fancy ‘radar’ modules as a sensor.
