Introduction: Holocron Lamp for the Discerning Jedi

Picture of Holocron Lamp for the Discerning Jedi

With the wave of your hand, the Holocron opens up keeping you on the light-side.

It's a Holocron lamp using the force open and close. With the wave of a hand over the top any discerning Jedi can access the path the the light.
This project is based around the Particle Photon IoT dev board, and I have to say this has been a joy to work on! In the trailer you can see a few images and videos from the start to the finish.

Step 3: Concept Idea

First step was to think of everything I needed to make this work, I settled on an IR proximity sensor, a servo for the movement and some super-bright white LED's for the light.

Step 4: First Steps

Picture of First Steps

Firstly I prototype the electronics on the breadboard and fleshed out all the details in the code. It works! this was obviously a relief.
Once all the code and circuitry had been proven it was time to begin printing the enclosure. I chose to use gold as this is a traditional Holocron material, the enclosure is designed to be press fit together, meaning there is hardly any need for support structure when printing.

Step 5: 3D Printing

Total printing time ran into about 30 hours, so best leave plenty of time!
Once I had the main enclosure parts printed it was time to customize the electronics and build them in.

Step 6: Firstly Add the IR (infrared) LED's Into the Holes Using As a Guide
