We built a real extending and retracting lightsaber from Star Wars! Finished just in time for the Acolyte, I'm so glad I can finally share Project JEDI with everyone. The lightsaber project files, links, and tutorials can be found below:

DISCLAIMER: This lightsaber is a prototype and is potentially dangerous to DIY. While I'm working to change that, I can't currently recommend this for anyone without engineering expertise and the will to troubleshoot for hours.
