Build A Starship Bridge Simulator With EmptyEpsilon

Who hasn’t dreamed of serving on the bridge of a Star Trek starship? Although the EmptyEpsilon project isn’t adorned with the Universe-famous LCARS user interface, it does provide a comprehensive simulation scenario, in a multiplayer setting. Designed as a LAN or WAN multiplayer game hosted by the server that also serves as the main screen, four to six additional devices are required to handle the non-captain tasks. These include helm, weapons, engineering, science and relay, which includes comms.

Scenarios are created by the game master, not unlike a D&D game, with the site providing a reference and various examples of how to go about this.

The free and open source game’s binaries can be obtained directly from the site, but it’s also available on Steam. The game isn’t limited to just Trek either, but scenarios can be crafted to fit whatever franchise or creative impulse feels right for that LAN party.

Obviously building the whole thing into a realistic starship bridge is optional, but it certainly looks like more fun that way.

Retro Calculator Panders To Trekkies… Or Trekkers

Back in 1976, when calculators were not common or cheap, a company named MEGO made the Star Trekulator: a calculator sporting a Star Trek theme. However, it was a bit odd since the calculator didn’t correspond to anything you ever saw on the TV show. It was essentially a very simple calculator with a Star Trek picture and some blinking LEDs. [Computer History Archives Project] has two examples of the rare calculator and shows them off, including the insides, in the video below. We’ve also included a vintage commercial for the device a little farther down.

Inside the 5-inch by 9.5-inch cabinet was an unremarkable printed circuit board. The main component was a TI calculator chip, but there were a surprising amount of other components, including three that [Computer History Archives Project] could not identify.

MEGO was known for making Star Trek toys, including a cassette player that (sorta) looked like a tricorder and communicator walkie-talkies. We wish they’d made the calculator look like some sort of prop from the show, although the beeping noises, we suppose, were supposed to sound like the Star Trek computers.

Honestly, we want to 3D print a case to replicate this with modern insides that can drive a display to put different Trek clips and sound effects out. Now, that would be something. Maybe [Michael Gardi] can take a look at it when he’s got a spare minute. If anything, the calculator looks too advanced to be on the original series. They should have gone VFD. Although Mr. Spock has been seen with a flight slide rule (an E6-B, if we recall). We prefer our props to look like the real ones, thank you.

Combadge Project Wants To Bring Trek Tech To Life

While there’s still something undeniably cool about the flip-open communicators used in the original Star Trek, the fact is, they don’t really look all that futuristic compared to modern mobile phones. But the upgraded “combadges” used in Star Trek: The Next Generation and its various large and small screen spin-offs — now that’s a tech we’re still trying to catch up to.

As it turns out, it might not be as far away as we thought. A company called Vocera actually put out a few models of WiFi “Communication Badges” in the early 2000s that were intended for hospital use, which these days can be had on eBay for as little as $25 USD. Unfortunately, they’re basically worthless without a proprietary back-end system. Or at least, that was the case before the Combadge project got involved.

Designed for folks who really want to start each conversation with a brisk tap on the chest, the primary project of Combadge is the Spin Doctor server, which is a drop-in replacement for the original software that controlled the Vocera badges. Or at least, that’s the goal. Right now not everything is working, but it’s at the point where you can connect multiple badges to a server, assign them users, and make calls between them.

It also features some early speech recognition capabilities, with transcriptions being generated for the voices picked up on each badge. Long-term, one of the goals is to be able to plug the output of this server into your home automation system. So you could tap your chest and ask the computer to turn on the front porch light, or as the documentation hopefully prophesies, start the coffee maker.

There hasn’t been much activity on the project in the last year or so, but perhaps that’s just because the right group of rabid nerds dedicated developers has yet to come onboard. Maybe the Hackaday community could lend a hand? After all, we know how much you like talking to your electronics. The hardware is cheap and the source is open, what more could you ask for?

How Star Trek Breached The Defences Of A Major Broadcaster

Back in 2020 in the brief lull between COVID lockdowns in the UK, I found myself abruptly on the move, with a very short time indeed to move my possessions into storage. As I was going through the accumulated electronic detritus of over four decades, I happened upon a grey box with some wires hanging out of it, and more than a few memories. This was a Sky VideoCrypt decoder, and the wires were part of the so-called “Season” interface to attach it to the serial port of a PC. It had this modification in the hope of catching some unauthorised free satellite TV, and in its day this particular hack caused some headaches for the broadcaster.

When More Than 4 Channels Was A Novelty

In the 1980s and early 1990s, there was very little in the way of digital broadcasting on either satellites or terrestrial networks, almost everything on TV was sent out as standard definition analogue video. The four terrestrial channels where I grew up were all free-to-air, and if you had a satellite dish you could point it at any one of a variety of satellites and receive more free-to-air channels if you didn’t mind most of them being in German. Premium satellite programming was encrypted though, either through a range of proprietary analogue schemes, or for the British broadcaster Sky’s offering, through their VideoCrypt system. This used a 64 kB buffer to store each line of video, and rotate it round any one of 256 points along its length, resulting in an unintelligible picture.

Sky was the UK’s big gorilla of premium broadcasters, a role they kept for many years, and which was only eroded by the advent of streaming services. As such they snapped up exclusive first access to much of the most desirable content of the day, restricting it to only their British pay-to-subscribe customers. A viewer in the UK who grumbled about Star Trek Next Generation not being on the BBC could at least cough up for Sky, but if they didn’t have a British address they were out of luck. It was in this commercial decision, whether it was based upon business or on licensing, that Sky unwittingly sowed the seeds of Videocrypt’s demise.

A Guide To Field Stripping Your Voyager Tricorder

For the last few years, [Mangy_Dog] has been working on what is easily the most technically and aesthetically impressive Star Trek tricorder prop the world has ever seen. With each new version of the hardware we’ve gotten the occasional peek under the hood or source code walk-through, but these limited presentations have made it somewhat difficult to really appreciate the scale of this undertaking.

But now thanks to this epic hour-long tour of the hardware and software that makes up version 2.5 of his Voyager tricorder, we can finally see just how incredible the engineering that’s gone into this project really is. Every detail has been meticulously considered to deliver a final product that’s not only as visually accurate as possible, but reliable enough to actually carry around.

Tricorder Tutorial Isn’t Just For Starfleet Cadets

For many of us, the most difficult aspect of a project comes when it’s time to document the thing. Did you take enough pictures? Did you remember all the little details that it took to put it together? Should you explain those handful of oddball quirks, even though you’re probably the only person in the world that knows how to trigger them?

Well, we can’t speak to how difficult it was for [Mangy_Dog] to put together this training video for his incredible Star Trek: Voyager tricorder replica, but we certainly approve of the final product. Presented with a faux-VHS intro that makes it feel like something that would have been shown to cast members during the legendary run the franchise had in the 1990s, the video covers the use and operation of this phenomenal prop in exquisite detail.

Replaceable batteries are standard again in the 2370s.

Now to be fair, [Mangy_Dog] has sold a few of his replicas to other Trek aficionados, and we’re willing to bet they went for a pretty penny. As such, maybe it’s not a huge surprise he’d need to put together a comprehensive guide on how to operate the device’s varied functions. Had this been a personal project there wouldn’t have been the need to record such a detailed walk-through of how it all works — so in that regard, we’re fortunate.

One of the most interesting things demonstrated in this video is how well [Mangy_Dog] managed to implement mundane features such as brightness and volume control without compromising the look of the prop itself. Rather than adding some incongruous switches or sliders, holding down various touch-sensitive buttons on the device brings up hidden menus that let you adjust system parameters. The project was impressive enough from the existing images and videos, but seeing just how deep the attention to detail goes is really a treat.

Previously we took a look at some of the work that [Mangy_Dog] has put into these gorgeous props, which (unsurprisingly) have taken years to develop. While they might not be able to contact an orbiting starship or diagnose somebody’s illness from across the room, it’s probably fair to say these are the most realistic tricorders ever produced — officially or otherwise.

2022 Sci-Fi Contest: The Winners Are In

The Sci-Fi Contest closed out on Monday, and we put our heads together and picked our favorites. And it was no easy task, because in addition to many of the projects simply looking stellar, many went all-out on the documentation as well, making these stellar examples that we can all learn from, whether you’re into sci-fi or not. But who are we kidding? From the responses we got, you are.

The Winners

[RubenFixit]’s Star Trek Shuttle Console is a Trek themed escape room in a box. The project’s extraordinary attention to detail and exhaustive project logs absolutely won our judges heart. From the LCARS graphics to the 3D printed isolinear chip bays and mimetic crystals, it’s all there. [Ruben] estimates about 300 hours of work went into this one, and it shows.

We had no shortage of robotic projects in the contest, but [RudyAramayo]’s R.O.B. won our judges over. This one is not a joke, weighing in at over 140 lbs of custom metalwork and righteous treads. It’s also made out of some expensive hardware all around, so maybe this isn’t your weekend-build robot. We love the comment on the Arduino test code suite: “For gods sake man, you must test your code when it becomes an autonomous vehicle.”

Finally, [zapwizard]’s Functional Razor Crest Control Lever is a prop and a video game controller in one. We can totally see Grogu playing with this, and we were wowed by the attention to detail in the physical build — with custom gears and a speed limiter — as well as the attention to prop-making detail. Some parts are custom-cut stainless steel plates. 3D printed parts are covered in aluminum tape and chemically aged. Awesome. Oh yeah, it’s also a working USB joystick.

These three winners will be receiving a $150 shopping spree at Digi-Key.
