Individual Neopixels Make Up This Lightsaber’s Blade

The lightsaber is an iconic weapon from the Star Wars franchise, designed in all sorts of shapes and colors. Several fan-made versions have been built as well, quite a few of which use the almost ubiquitous neopixel. [Tirenoth] decided to build his first lightsaber using a series of neopixels, but decided on a unique build method.

Instead of the usual strip of neopixels, [Tirenoth] chose to use a bunch of neopixels in the 5mm LED form-factor. [Tirenoth] soldered each LED’s 5v pins and GND pins to the same pins on the next, rotating each LED 180 degrees, building a tower of pixels. The data in and out pins are soldered to the next (and previous) LED as well. This allows the series of LEDs to be a bit more stable physically, and allows them to be stacked close together, one on top of the other.

To control the neopixels, a Proffieboard is used, an open-source lightsaber controller. The Proffieboard uses an STM32 microcontroller and allows you to hook up LEDs or neopixels as well as a speaker. Its open-source software allows the animation of the pixels and the playing of sounds. It’s designed specifically for lightsaber builds and is programmed via the Arduino IDE.

[Tirenoth] has some nice pictures of the build in process and, of course some nice pics of the final result. He suggests that the blade would be the first to break in battle, though. There’s been a few lightsaber builds over the years, like this lightsaber with rave mode, or this lightsaber made with real lasers.

Vintage Terminal Converted For Galactic Use In Time For May The Fourth

“Not as clumsy or random as Windows. An elegant terminal, for a more civilized age.” [Ben Kenobi] might well have said that about the Hewlett-Packard 264x-series of serial terminals, in use starting at just about the time the original installment of the Star Wars franchise was released.  With their wide-screen CRTs and toaster-oven aesthetic, they were oddballs in the terminal market, and [CuriousMarc] has gone and made one even odder by converting an H-P 2645A to display the Aurebesh character set from the movies.

A look under the hood of this lovely bit of retrocomputing history makes one think the designers almost foresaw the need to add support for a made-up language nearly half a century later. The terminal has a backplane and bus for pluggable cards, one of which carries the ROMs that [Marc] extracted and reprogrammed with the Aurebesh characters. He had a little trouble at first, needing to bodge the chip select and forgetting that he had made other “special modifications” to the terminal. The video below shows the results, along with some fatherly mortification of his daughters and a suitable tribute to the lately late [Peter Mayhew], he who donned the Wookiee suit and made a seven-foot space Sasquatch lovable.

Star Wars Electrostaff Effect, Done With Spinning LEDs

[Bithead] wanted to make a prop replica of an Electrostaff from Star Wars, but wasn’t sure how best to create the “crackling arcs of energy” effect at the business ends. After a few false starts, he decided to leverage the persistence of vision effect by spinning LEDs in more than one axis to create helical arcs of light and it seems that this method has some potential.

Many multi-axis persistence of vision devices use a component called a slip ring in order to maintain electrical connections across rotating parts, but [Bithead] had a simpler plan: 3D print a frame and give each axis its own battery. No centralized power source means a quicker prototype without any specialized parts, and therefore a faster proof of concept to test the idea.

[Bithead] already has improvements planned for a new version, but you can see the current prototype in action in the short video embedded after the break.

Humanity Creates A Cloud Of Space Garbage, Again

With the destruction of the Microsat-R reconnaissance satellite on March 27th, India became the fourth country in history to successfully hit an orbiting satellite with a surface-launched weapon. While Microsat-R was indeed a military satellite, there was no hostile intent; the spacecraft was one of India’s own, launched earlier in the year. This follows the examples of previous anti-satellite (ASAT) weapons tests performed by the United States, Russia, and China, all of which targeted domestic spacecraft.

Yet despite the long history of ASAT weapon development among space-fairing nations, India’s recent test has come under considerable scrutiny. Historically, the peak of such testing was during the 1970’s as part of the Cold War rivalry between the United States and then Soviet Union. Humanity’s utilization of space in that era was limited, and the clouds of debris created by the destruction of the target spacecraft were of limited consequence. But today, with a permanently manned outpost in low Earth orbit and rapid commercial launches, space is simply too congested to risk similar experiments. The international community has strongly condemned the recent test as irresponsible.

For their part, India believes they have the right to develop their own defensive capabilities as other nations have before them, especially in light of their increasingly active space program. Prime Minister Narendra Modi released a statement reiterating that the test was not meant to be a provocative act:

Today’s anti-satellite missile will give a new strength to the country in terms of India’s security and a vision of developed journey. I want to assure the world today that it was not directed against anybody.

India has always been against arms race in space and there has been no change in this policy. This test of today does not violate any kind of international law or treaty agreements. We want to use modern technology for the protection and welfare of 130 million [1.3 Billion] citizens of the country.

Further, the Indian Space Research Organisation (ISRO) rejects claims that the test caused any serious danger to other spacecraft. They maintain that the test was carefully orchestrated to that any debris created would renter the Earth’s atmosphere within a matter of months; an assertion that’s been met with criticism by NASA.

So was the Indian ASAT test, known as Mission Shakti, really a danger to international space interests? How does it differ from the earlier tests carried out by other countries? Perhaps most importantly, why do we seem so fascinated with blowing stuff up in space?

The Empire Strikes Back With The ESP8266

Like many of us, [Matthew Wentworth] is always looking for a reason to build something. So when he found a 3D model of the “DF.9” laser turret from The Empire Strikes Back intended for Star Wars board games on Thingiverse, he decided it was a perfect excuse opportunity to not only try his hand at remixing an existing 3D design, but adding electronics to it to create something interactive.

As the model was originally intended for a board game, it was obviously quite small. So the first order of business was scaling everything up to twice the original dimensions. As [Matthew] notes, the fact that it still looks so good when expanded by such a large degree is a credit to how detailed the original model is. Once blown up to more useful proportions, he modified the head of the turret as well as the barrel to accept the electronics he planned on grafting into the model.

He created a mount for a standard nine gram servo inside the head of the turret which allows it to rotate, and the barrel got an LED stuck in the end. Both of which are controlled with a NodeMCU ESP8266 development board, allowing [Matthew] to control the direction and intensity of the pew-pew over WiFi. He mentions that in the future he would like to add sound effects that are synchronized to the turret rotation and LED blinking.

For the software side of the project, he used Blynk to quickly build a smartphone interface for the turret. This is the first time he had used Blynk, and reports that outside of a little trial and error, it was some of the easiest code he’s ever written for the Arduino. This is a sentiment we’ve been seeing a lot of recently towards Blynk, and it’s interesting to see how often it shows up in ESP8266 projects now.

Looking ahead [Matthew] says he wants to paint and detail the turret, as the bright orange color scheme probably wouldn’t do terribly well on Hoth. If he can manage the time, he’d also like to add it to the long list of OpenCV-powered turrets that hackers love harassing their friends and family with.

A Trove Of Cosplay Prop Making Tutorials And Blueprints

[CutTransformGlue] recently posted a build video for “Making Rey’s Star Wars Blaster“, embedded after the break. The construction uses layered MDF sheets to build up the blaster, and it’s a treat to see it taking shape, ending with an amazing paint job. It’s a good way to learn about the techniques used to bring such props to life and help you hone your skills. But digging deeper led us down an awesome rabbit hole.

[CutTransformGlue] got plans for Rey’s Blaster from the Punished Props Academy – a prop and costume making team from Seattle committed to “transforming passionate fans into confident, skillful makers”. These folks have built a wide variety of projects ranging from guns, weapons, costumes, props and more, and are obviously extremely skilled at what they do. But they aren’t keeping those skills to themselves and in a series of posts and videos they are sharing with us such varied skills as Foamsmithing (gotta love that coinage), Molding, Casting, Painting, 3D printing, Vacuum Forming and electronics. If you’d like more information about supplies, check out the Tools and Materials section. And if all of this has given you the itch to build a Skyrim Wuuthrad or a Halo4 Sniper Rifle, head over to the amazing Free Blueprints section for a treasure chest full of downloads.

Like we said earlier, if building such stuff is your thing, it’s a rabbit hole from which you’ll find it extremely difficult to extract yourself. Have fun.

Wearable Speeder Bikes Are Ready For A Night Out

While Hackaday is about as far from a fashion blog as you can possibly get, we have to admit we’re absolutely loving the [bithead942] Winter 2018 Collection. His wife and daughter recently got to model his latest must have design: wearable Star Wars speeder bikes; and judging by the video after the break they were certainly some of the best dressed at the Thanksgiving parade.

[bithead942] started the build by taking careful measurements of a vintage speeder bike model kit his wife had, which allowed to accurately recreate the iconic look of the vehicles as they were seen in Return of the Jedi . But to do them justice, the final “bikes” would need to be around three meters (ten feet) long, which immediately posed a problem. What kind of material could support itself over that length while still being light enough to wear for extended periods of time?

The answer came, as it often does, from the local hardware store. He found that a combination of Schedule 80 and 40 PVC pipe was a perfect material: strong enough to support the desired dimensions without bending, light enough that the final bike wouldn’t be uncomfortable to wear, easy to bend with heat, and perhaps best of all, cheap and readily available. The PVC frame was then covered with chicken wire and thin flexible foam to give it a filled out look without weighing them down.

Even though he had a strict weight limit on the build, [bithead942] couldn’t help but add in some electronics to complete the effect. The LED festooned control panel allows the ladies to trigger different sound effects from the movie stored on a Adafruit Mini FX Sound Board, which is connected to a 20W Class D amplifier and a pair of 400 watt car stereo speakers. He says the resulting playback was loud enough to hear outside during the parade, and only added a few pounds to the overall build.

These may be the bikes you’re looking for, but they’re definitely not the first we’ve featured on Hackakday. Meanwhile you’d be wise not to underestimate the lowly PVC pipe when designing your next project. From a hacked together drill press for your Dremel to a planetarium for you and your closest dozen or so friends, there’s little you can’t build with this plentiful material.
