PLEASE NOTE THAT THIS PROJECT IS A PROTOTYPE AND POTENTIALLY DANGEROUS TO DIY - WHILE WE’RE WORKING TO CHANGE THAT, THIS CURRENT DOCUMENTATION IS PROVIDED AS A LEARNING RESOURCE, NOT A DETAILED STEP-BY-STEP.
This is the upgraded version of our previous V1 retractable lightsaber design! This version has a solid, energetic blade from all angles, thanks to two high-powered COB LED strips and a spinning mechanism that rotates the entire inner hilt assembly. This saber features near-instant extension with a new mechanical clutch mechanism, as well as faster retraction than the previous version. Powered by five LiPo batteries, the electronics are controlled through the Proffieboard V3.9.
DO NOT TRY THIS AT HOME! THIS PROJECT DOCUMENTATION IS INTENDED AS AN EDUCATIONAL LEARNING RESOURCE ONLY, NOT TO BE REPLICATED. THIS PROJECT IS DANGEROUS AND BEARS NUMEROUS RISKS DUE TO THE POWERFUL LIPO BATTERIES.

Release Notes
- The LED strips need to be exactly the same extended length, or else one of them will be floppy upon extension
- Currently the LED strips are prone to failure with the high stresses, need to design shock relief for them
- Need a Dremel or similar tool to cut off protruding end of magician’s cane
