Behold The Most Beautifully Ambitious Starship Simulator Yet

July 29, 2026 by Donald Papp 23 Comments

[Kevin Kelm] created something wondrous: Halcyon Dawn, an utterly unique and desperately challenging game that is equal parts intricate starship simulator, imposing hardware console, video game, and love letter to John Scalzi’s Old Man’s War book series. Grab a beverage for this one, because it’s chock-full of detail.

First, how is it played? The simulator represents the ship Halcyon Dawn, a stolen and renamed vessel, and the player representing its sole crew member. The ship’s new mission is to establish a home for its payload of genetically-engineered unfortunates, escaping a cruel sort of indentured military servitude. The former masters of course have a very different view of the whole situation, throwing around terms like “treason” and “theft” and in general preferring the version of the desperate protagonist they had the most control over.

Aluminum extrusion, laser-cut panels, and custom PCBs for interfacing physical controls and displays make up the bulk of the build.

As the player is meant to be operating the ship on their own, the cockpit is imposing. All 152 controls and six screens are meaningful and will be needed to pilot the Halcyon Dawn, survive hostile actions, repel boarding attempts, mine and refine vast amounts of raw materials, and in general keep the ship running and intact until an autofactory can be deployed in orbit of a suitable planet to create a new home.

All easier said than done. It’s one thing to pilot and tweak a temperamental ship, but doing so while also performing damage control and thwarting a boarding attempt by manipulating life support is quite another. Want more details? Gameplay is documented here and the physical controls have their own library.

The product of a year of focused work, [Kevin] – now retired – pointed his decades of hardware and software experience at Halcyon Dawn after realizing one night that everything he needed to create it already existed. How this whole project came to be is also a tribute to the amazing tools and equipment that hobbyists and hackers of all kinds now have to turn an idea into something that actually exists in the world. Even so, it was a load of work he is not keen to repeat. Don’t miss the technical deep-dive and photo gallery of the build.

While the game itself — being a fan-made derivative of Scalzi’s work (and useless without the custom-made hardware console) — isn’t being released, [Kevin] has shared the underlying hardware framework it is built on. Enigma is an ESP32-based set of input and output PCBs made for integrating switches, knobs, displays, relays, and more with a Python library to make them easy to work with.

Starship simulators are a wonderful subset of projects, and every one is different from the last. Something about physical builds really works for them, and while we’ve seen a camper trailer converted to starship simulator [Kevin]’s project focuses the whole experience beautifully into the single-person console you see here. Watch a video of Halcyon Dawn running in an arcade-like “attract” mode embedded just below.

Announcing: The 2022 Hackaday.io Sci-Fi Contest

March 10, 2022 by Elliot Williams 6 Comments

Ladies and Gentlemen, Sentient robots, Travellers from the distant future, or Aliens from the outer rim, it’s time to enter the 2022 Hackaday.io Sci-Fi Contest!

We last ran the Sci-Fi contest in the far, far past — before the Voigt-Kampff machine was detecting replicants on the gritty streets of 2019’s LA. Back then, we had some out-of-this-world entries. It’s time for the sequel.

Thanks to Digi-Key, the contest’s sponsor, your best blaster, your coolest costume, or your most righteous robot could win you one of three $150 shopping sprees in their parts warehouse. Create a Hackaday.io project, enter it in the contest, and you’re set. You might as well do that right now, but the contest closes on April 25th.

Sci-Fi is all about the looks, so if it’s purely decorative, be sure to blind us with science (fiction). If your project actually functions, so much the better! Of course we’d like to know how it works and how you made it, so documentation of the project is the other big scoring category. Whatever it is, it’s got to be sci-fi, and it’s got to have some electronics in it.

If you’re looking for inspiration, you could do a lot worse than to check out [Jerome Kelty]’s Animatronic Stargate Helmet, that not coincidentally took the grand prize last time around. It’s an artistic and engineering masterpiece all rolled into one, and the description of how it’s made is just as extensive. [Jochen Alt]’s “Paul” robot isn’t out of any particular sci-fi franchise that we know, but of rolling on one ball and reciting robot poetry, it absolutely should be.

Honorable Mentions

In addition to the overall prizes, we’ll be recognizing the best projects in the following honorable mention categories:

Star Star: Whether you’re “beam me up” or “use the force”, fans of either of the “Star” franchises are eligible for this honorable mention.
ExoSuit: This category recognizes sci-fi creations that you can wear. Costumes and armor fit in here.
Stolen off the Set: If your blaster looks exactly like Han Solo’s, you’re a winner here. This is the category for your best prop replica.
Living in the Future: If your sci-fi device was purely fantasy when imagined, but now it’s realizable, you’re living in the future. A working tricorder or a functioning robot companion would fit in fine here.
The Most Important Device: Has no function, but it certainly looks like it does. Just blinking lights that blink back and forth, yet the government spent millions of dollars on it.

You don’t have to tell us where your project fits in. We’ve got you covered.

Engage!

Get started now by creating a project page on Hackaday.io. In the left sidebar of your project page, use the “Submit Project To” button to enter in the 2022 Sci-Fi Contest.

You have from now until April 25, 2022 to get it finished. Of course, if your time machine actually works, you can finish it whenever. Check out the Hackaday.io contest page for all the fine print.

Spaceship Repair CTF Covers Hardware Hacker Essentials

March 3, 2022 by Arya Voronova 15 Comments

At even vaguely infosec-related conferences, CTFs are a staple. For KernelCon 2021, [Tyler Rosonke] resolved to create a challenge breaking the traditions, entertaining and teaching people in a different way, while satisfying the constraints of that year’s remote participation plans. His imagination went wild in all the right places, and a beautifully executed multi-step hardware challenge was built – only in two copies!

Story behind the challenge? Your broken spaceship has to be repaired so that you can escape the planet you’re stuck on. The idea was to get a skilled, seasoned hacker solving challenges for our learning and amusement – and that turned out to be none other than [Joe “Kingpin” Grand]!

The modules themselves are what caught our attention. Designed to cover a wide array of hardware hacker skills, they cover soldering, signal sniffing, logic gates, EEPROM dumping and more – and you have to apply all of these successfully for liftoff. If you thought “there’s gotta be a 555 involved”, you weren’t wrong, either, there’s a module where you have to reconfigure a circuit with one!

KernelCon is a volunteer-driven infosec conference in Omaha, and its 2022 installment starts in a month – we can’t wait to see what it brings! Anyone doing hardware CTFs will have something to learn from their stories, it seems. The hacking session, from start to finish, was recorded for our viewing pleasure; linked below as an hour and a half video, it should be a great background for your own evening of reverse-engineering for leisure!

This isn’t the first time we’ve covered [Tyler]’s handiwork, either. In 2020, he programmed a batch of KernelCon badges while employing clothespins as ISP clips. Security conferences have most certainly learned just how much fun you can have with hardware, and if you ever need a case study for that, our review of 2019 CypherCon won’t leave you hanging.

Project Orion: Detonating Nuclear Bombs For Thrust

August 13, 2018 by Steven Dufresne 63 Comments

Rockets with nuclear bombs for propulsion sounds like a Wile E. Coyote cartoon, but it has been seriously considered as an option for the space program. Chemical rockets combust a fuel with an oxidizer within themselves and exhaust the result out the back, causing the rocket to move in the opposite direction. What if instead, you used the higher energy density of nuclear fission by detonating nuclear bombs?

Detonating the bombs within a combustion chamber would destroy the vehicle so instead you’d do so from outside and behind. Each bomb would include a little propellant which would be thrown as plasma against the back of the vehicle, giving it a brief, but powerful push.

That’s just what a group of top physicists and engineers at General Atomic worked on between 1958 and 1965 under the name, Project Orion. They came close to doing nuclear testing a few times and did have success with smaller tests, exploding a series of chemical bombs which pushed a 270-pound craft up 185 feet as you’ll see below.

Delta Clipper: A 1990s Reusable Single-Stage To Orbit Spaceship Prototype

July 19, 2018 by Steven Dufresne 50 Comments

With all the talk of SpaceX and Blue Origin sending rockets to orbit and vertically landing part or all of them back on Earth for reuse you’d think that they were the first to try it. Nothing can be further from the truth. Back in the 1990s, a small team backed by McDonnell Douglas and the US government vertically launched and landed versions of a rocket called the Delta Clipper. It didn’t go to orbit but it did perform some extraordinary feats.

Origin Of The Delta Clipper

The Delta Clipper was an unmanned demonstrator launch vehicle flown from 1993 to 1996 for testing vertical takeoff and landing (VTOL) single-stage to orbit (SSTO) technology. For anyone who watched SpaceX testing VTOL with its Grasshopper vehicle in 2012/13, the Delta Clipper’s maneuvers would look very familiar.

Initially, it was funded by the Strategic Defence Initiative Organization (SDIO). Many may remember SDI as “Star Wars”, the proposed defence system against ballistic missiles which had political traction during the 1980s up to the end of the Cold War.

Ultimately, the SDIO wanted a suborbital recoverable rocket capable of carrying a 3,000 lb payload to an altitude of 284 miles (457 km), which is around the altitude of the International Space Station. It also had to return with a soft landing to a precise location and be able to fly again in three to seven days. Part of the goal was to have a means of rapidly replacing military satellites should there be a national emergency.

The plan was to start with an “X” subscale vehicle which would demonstrate vertical takeoff and landing and do so again in three to seven days. A “Y” orbital prototype would follow that. In August 1991, McDonnell-Douglas won the contract for the “X” version and the possible future “Y” one. The following is the story of that vehicle and its amazing feats.

Mom, I’ll Be In My Attic Spaceship

January 8, 2018 by Roger Cheng 11 Comments

Most attics sit empty or serve as storage space to keep infrequently used items out of sight. Many of us keep boxes of half-completed abandoned projects there. But some people turn the attic itself into the project: this past Christmas some very lucky children received a spaceship playroom in the attic. [Titospot] shared his project via an Imgur album.

The cramped space lends itself to the theme as real-life spacecraft have never been known for interior spaciousness. The builders are skilled enough at standard home improvement tasks of building out and finishing a room, then they took their step into the unknown by building a control panel for the spaceship. [Titospot’s] caption text reveals some insecurity with his electronics build quality but, hey, we all had to start somewhere! Few of our first electronics projects were as much fun as his spaceship control panel. Packed with buttons and switches that trigger light and sound, it is sure to become the focus of many imaginary adventures to galaxies far, far away.

Life Sized Lego Spaceship Parts

May 11, 2015 by Brian Benchoff 18 Comments

Ah, 1980s space Lego sets. You may think the pirate ship and castle sets are cooler, but you’re wrong, because spaceship. spaceship. spaceship.

These space Lego sets had some very interesting parts, with tiny two-by sloped pieces printed with Lego analogs of computers, monitors, phones, intercoms, speakers, control panels, and everything else that makes a voxellated spaceship fly to the moon. Now, these pieces are functional, and they’re nearly life-size.

[Love Hultén] took these fantastic parts, modeled them, and scaled them up to six times normal Lego dimensions. These blocks were then fitted with buttons, displays, the guts of an old telephone, and all the other accoutrements to make these bricks functional. Two computer blocks can be connected together, and it will play video games with a Lego-shaped controller. The intercom works, and the buttons on control panels can be used to turn on lights.

It should be noted the Lego family is more than just the small bricks that really hurt when you step on them. Duplo, the blocks made for children who would stuff Lego down their own throats, is twice the size of Lego. Quatro are blocks made for toddlers, and are twice the size of Duplo and four times the size of Lego. Since [Love] made blocks that are six times the size of normal Lego blocks, we’ll leave it up to the comments to determine what this class of blocks should be named.

Video below.
