If you are looking for a Star Wars light sabre, sometimes your choices can be a little disappointing. “Replica” sabres from toy and novelty vendors may superficially look the part, but with their tinny speakers and lacklustre show of LEDs they often have less of the Force about them and more of the Farce.
[Jeremy Lee] offers a solution; he’s built what he claims to be the brightest light sabre in the world. That’s a bold assertion, and one which we think might even throw down a gauntlet to other sabre builders and spark an arms race among Jedi wannabes.
The super-bright sabre uses a 144 LED double-sided strip of Neopixels in a polycarbonate tube, with a DC to DC converter powered by a 100mAH LiPo battery. Sound effects come from a SparkFun Pro Micro powering a 2W speaker through a small audio amplifier. The handle meanwhile is constructed from PVC pipe fittings.
His first attempt at the sabre had the LEDs at full power, and promptly melted his tube. Thus the final version runs at 40% of its maximum rating, with a “burst” mode for those moments at which combat demands it.
His write-up is a series of posts, with plenty of video at all points. It might seem odd to show you the shortest of them here at only a few seconds long, but since the unique selling point is its brightness we think the best way to show that is at night.

[TVMiller]’s description of his project is epic enough to deserve a literal copy-paste (something our readers often praise us about). In his own words, “Having discovered several spare Midichlorians in my liquor cabinet, I trained and applied them to opening a large cumbersome gate. The FORCE motion travels through my inner what-nots and is translated by the Pebble Classic accelerometer toggling a command sent to the (Particle) Cloud (City) which returns to the Particle Photon triggering a TIP120 to fire a button on an existing RF transceiver. May the ridiculous hand gestures be with you, always.” Thus was born the Gate Jedi , and you’ll need exactly 47 Midichlorians, and some other trivial parts, to build one.
The Pebble watch hooks up to his android smart phone. A Pebble
(android) app sends the accelerometer data to the Particle (previously called Spark) cloud service. From there, the data is pushed to the Photon IoT board which runs a few lines of code. Output from the Photon turns on a TIP120 power transistor, which in turn triggers the existing RF trans receiver that opens the Gate.
This looks way cooler than the Light Sabre hacks. Check out the video of him summoning the Force. And if you’d like to do more, try integrating gesture controls with this Pebble Watch hack that turns it into a home automation controller.

[Mario the Magician] wrote in to let us know that he makes Hackaday a priority every morning with his coffee. Well, so do we. He also included a link to his homepage when submitting this revelation. The juicy details that are as much of a fix as the caffeine in the coffee are missing from his posts. But the hacks are solid.
Magicians are hackers. If you could go out and buy the props, the concept are unlikely to impress anyone. [Mario] demonstrates his Nickel Box and a Jedi Mind Trick he built. The Nickel Box is a mechanical contraption that somehow transports a coin from one part of a cigar box to a tiny little enclosure on top of it. The Jedi Mind Trick uses a microcontroller and an old Star Wars soundtrack cassette tape box to put on a light and sound show while it recovers your chosen card from a shuffled deck. Great demonstrations, but no word on what’s going on inside.
[Mario’s] also has a collection of… performance oddities. His talking television takes an audio input and displays a 1950’s-esque oscilloscope effect on an old TV. He’s attempting to stop his heart, or burn the house down, or both with a flyback transformer lightning box. And his drawing automaton, well, you’ll just have to see it.
We believe in electrons, not magic (even though some say there are no electrons). So we want to know how those magic props are built. Like any good magician, [Mario] probably won’t reveal his secrets. If you’ve got the goods this your chance. Write a post detailing your magical prop builds and send them our way. If it’s well done we’ll feature it here on Hackaday.
