Star Wars-Inspired Cosplay Prop Uses Old Vintage Camera

Lots of people make replica lightsabers from Star Wars or tricorders from Star Trek. Not so many people have tried to recreate the binoculars from The Last Jedi, but [The Smugglers Room] whipped up a pretty rad pair from old parts.

It’s more of an inspired build rather than screen-accurate, but they’re still pretty neat. A Bell & Howell camera was the basis for the binoculars used in the film, in fact, and this build starts with the same tri-lens model. Found vintage objects are often used in sci-fi with some modifications, but more commonly in lower-budget productions. Star Wars can do it too, though, it seems.

Turning them into binoculars requires the construction of a viewfinder, which was made out of hand-cut Sintra PVC foam board. Lots of leather wrap had to be removed from the camera, too, which offered a happy accident—it left a heavily-weathered aluminum surface that looked great for a Star Wars prop. A few random controls were then added to disguise the camera as an advanced pair of futuristic binoculars. LED lighting was also installed internally to make the build glow as if it actually contained some powered sci-fi optics. It also got a hand-made leather strap for that rugged aesthetic so fitting for the film.

It’s not a functional build; we’d love to see someone build a set of AR or rangefinder binoculars that still look the part. However, this would be a great addition to any Poe Dameron costume you might have planned for the next upcoming Comic Con.

Here’s our question, though. Does it suck you out of your suspension of disbelief when filmmakers use found objects as the basis for props? Or is it a neat thing when you spot such an example? Video after the break.

Star Wars Pit Droid Has A Jetson Brain

In the Star Wars universe, pit droids are little foldable robots that perform automated repairs on spacecraft and the like. They were introduced in 1999’s The Phantom Menace, and beyond the podracing scenes, are probably the only good thing to come out of that particular film.

[Goran Vuksic] wanted a pit droid of his own, and reasoned that if he was going to go through the trouble of sanding and painting all the 3D printed components so they look like the real bot, he might as well add some smarts to it. While this droid won’t be fixing podracers anytime soon, its onboard Jetson Orin Nano Developer Kit does pack a considerable amount of processing under that dome.

A webcam mounted in the bot’s eye socket is connected to the Jetson, which is running an image detection and identification routine based on the example code provided by NVIDIA. The single-board computer uses a relay to blink some LEDs on and off when a human is detected, and a pair of servos pan-and-tilt the bot’s head towards whoever has caught its gaze.

It’s no surprise that [Goran] picked the Jetson Orin over competing SBCs for this task — in our review of the Orin Nano Developer Kit a few months ago, we found it was able to hit nearly 200 frames per second while performing this sort of real-time image analysis. So there’s plenty of room to grow should he want to integrate more complex image recognition tasks.

For example, he could follow in the footsteps of [Kris Kersey], and put a functional data overlay on top of the video to give his bot Iron Man vision.

Hackaday Podcast 224: Star Wars Holograms, Tricorders, And Other Sensors

Elliot and Al got together to discuss this week’s projects, and you’re invited! You’ll hear news about replaceable batteries in the EU, along with some news about the Hackaday Op Amp Challenge winners and the start of a new contest. This week’s choice hacks ranged from a Star Wars-style volumetric display, navigation using cosmic rays, measuring car speed with microphones, and a crazy 3D printing technique that will blow you away.

There’s plenty more where that came from. Ever tried to land a model rocket vertically? How about building a punched card reader? The can’t miss articles this week cover a thermal camera review and the unintended consequences if AM radio bites the dust.

A Volumetric Display With A Star Wars Look And Feel

It may not exactly be what [Princess Leia] used to beg [Obi-Wan] for help, but this Star Wars-inspired volumetric display is still a pretty cool hack, and with plenty of extra points for style.

In some ways, [Maker Mac]’s design is a bit like a 3D printer for images, in that it displays slices of a solid model onto closely spaced planar surfaces. Sounds simple enough, but there are a lot of clever details in this build. The main component is a lightly modified LCD projector, a DLP-based machine with an RGB color wheel. By removing the color wheel from the projector’s optical path and hooking its sync sensor up to the control electronics, [Mac] is able to increase the framerate of the display, at the cost of color, of course. Other optical elements include a mirror to direct the projected images upwards, and a shutter harvested from an old pair of 3D TV glasses.

Electroplating Makes 3D-Printed Star Wars Prop Shine

3D printing is known for producing parts with a fairly average finish at best. Even the smoothest resin prints are still fairly plasticky and dull in appearance. However, it’s possible to do much better if you get creative with electroplating. This thermal detonator prop from [HEN3DRIK] shows just how good a 3D print can look with a little post-processing and some chemical help.

[HEN3DRIK] started with a Star Wars thermal detonator model found online, and printed it in resin for the best possible surface finish from the get go. The parts were cleaned after printing and cured, as per usual resin processing techniques. From there, fine steel wool and sandpaper was used to make the print as smooth as possible. A conductive layer of copper paint was then sprayed on with an airbrush, with mating surfaces masked off to avoid ruining the fit.

The part was then dunked in an acidic copper bath while attached to a power source, and gently rotated during the electroplating process. The results were excellent, resulting in near-mirror finish copper-plated parts after polishing. Nickel was then plated on top to get the prop to the proper silver color. The prop was finally then assembled with an Arduino Nano inside to run several LEDs for visual effect.

Electroplating isn’t just for making things pretty. It can also add strength to your 3D prints, too! Video after the break.

Ride-on Star Wars Land Speeder Gets A Real Jet Engine

When it comes to children’s ride-on toys, the Star Wars Land Speeder is one of the cooler examples out there. However, with weedy 12-volt motors, they certainly don’t move quickly. [Joel Creates] decided to fix all that, hopping up his land speeder with a real jet engine.

First, the original drivetrain was removed, with new wheels installed underneath. Initially, it was set up with the front wheels steering, while the rear wheels were left to caster freely. A RC jet engine was installed in the center engine slot on the back of the land speeder, and was controlled via a standard 2-channel RC transmitter.

The jet engine worked, but the wheel configuration led to the speeder simply doing donuts. With the speeder reconfigured with rear wheels locked in place, the speeder handled much more predictably. Testing space was limited to a carpark, so high-speed running was out of the question. However, based on the limited testing achieved, it looks as though the speeder would be capable of a decent clip with the throttle maxed out.

It’s not a practical build, but it sure looks like a fun one. [Joel Creates] has big dreams of adding two more jet engines and taking it out to a runway for high-speed testing, and that’s something we’d love to see.

RC jet engines are a bit of a YouTube fad right now, showing up on everything from RC cars to Teslas. Video after the break.

2022 Sci-Fi Contest: A Very Star Wars Door

Every fan of the original Star Wars trilogy knows the plight of Han Solo, who was so cruelly frozen in carbonite by Imperial forces. [erv.plecter] came into possession of a replica Solo, this time frozen in polyurethane, and set about using it as the door for a home theater setup.

Just like in the movie, there are a series of controls and lights on the side of the door, clearly intended to represent the state of the carbonite block and the smuggler trapped within. This was achieved with the use of a SAMD51 microcontroller, which controls five meters of WS2812B LED strip along with a small OLED display.

There’s also an amazing little smoke effect, built using a vape inhaler. These devices have proved popular for all kinds of theme builds and costumes, as it turns out. They’re a great way to produce a visible fog or smoke in a tiny, compact package.

[erv.plecter] was kind enough to share plenty of details on the build, including how the polyurethane cast was assembled into the door. The final result looks remarkably authentic, and would surely prove a hit at any Star Wars movie night. Just don’t spoil things by forcing everyone to sit through Revenge of the Sith.
