Books you should read: The Bridge

A few weeks ago, Amazon’s crack marketing AI decided to recommend a few books for me. That AI must be getting better because instead of the latest special-edition Twilight books, I was greeted with this:

“The asteroid was called the Hand of God when it hit.”

That’s the first sentence of The Bridge, a new Sci-Fi book by Leonard Petracci. If you think that line sucks you in, wait until you read the whole first chapter.

The Bridge is solidly in the generation ship trope. A voyage hundreds or even thousands of years long, with no sleep or stasis pods. The original crew knows they have no hope of seeing their destination, nor will their children and grandchildren. Heinlein delved into it with Orphans of the Sky. Even Robert Goddard himself discussed generation ships in The Last Migration.

I wouldn’t call The Bridge hard Sci-Fi — and that’s perfectly fine. Leonard isn’t going for scientific accuracy. It’s a great character driven story. If you enjoyed a book like Ready Player One, you’ll probably enjoy this.

The Bridge Is the story of Dandelion 14, a ship carrying people of Earth to a new planet. At some point during the journey, Dandelion 14 was struck by an asteroid, which split the ship in two. Only a few wires and cables keep the halves of the ship together. The crew on both sides of the ship survived, but they had no way to communicate. They do catch glimpses of each other in the windows though.

Much of the story is told in the first person by Horatius, a young man born hundreds of years after the asteroid strike. Horatius’ side of the ship has a population of one thousand, carefully measured at each census. They’ve lost knowledge of how to operate the ship’s systems, but they are surviving. Most of the population are gardeners, but there are doctors, cooks, porters, and a few historians. At four years old, Horatius is selected to become a gardener, like his father was before him. But Horatius has higher aspirations. He longs to become a historian to learn the secrets of the generations that came before him and to write his own story down for those who will come after.

Horatius sees the faces of the people on the other side of the ship as well. Gaunt, hungry, often fighting with knives or other weapons. A stark contrast to the well-fed people on his side of the vessel. The exception is one red-haired girl about his age. He often finds her staring back at him, watching him.

Horatius might have been chosen as a gardener, but he’s clever — a fact that sometimes gets him in trouble. His life takes an abrupt turn when the sleeping ship awakens with an announcement blaring “Systems Rebooting, Ship damage assessed. Reuniting the two halves of the ship and restoring airlock, approximately twenty-four hours until complete.”

The hardest part of writing a book review is not giving too much away. While I won’t tell you much more about the plot for The Bridge, I can tell a bit about how the book came about. You might call this book a hack of the publishing system. Leonard Petracci is also known as leoduhvinci on Reddit. The Bridge started life as Leonard’s response to a post on /r/writingprompts. The prompt went like this:

After almost 1,000 years the population of a generation ship has lost the ability to understand most technology and now lives at a pre-industrial level. Today the ship reaches its destination and the automated systems come back online.

Leonard ’s response to the prompt shot straight to the top, and became the first chapter of The Bridge. Chapter 2 followed soon after. In only a few months, the book was complete. Available on Reddit, and on Leonard’s website. The Bridge is also available on Amazon for Kindle, and on paper from Amazon’s CreateSpace.

The only real criticism I have about The Bridge is the ending. The book’s resolution felt a bit rushed. It would have been nice to have a few more pages telling us what happened to the characters after the major events of the book. Leonard is planning a sequel though, and he teases this in the final pages.

You can start reading The Bridge right now on Leonard’s website. He has the entire book online for free for a few more weeks. If you’ve missed the free period, the Kindle edition is currently $2.99.

Jean-Luc PYcARD is a Pocketable Python Development Platform

It’s a good thing that a ridiculous pun and a screenprint of Jean-Luc Picard on the bottom of the board is enough to qualify for the 2017 Hackaday Sci-Fi Contest, because [bobricius]’s Python-plus-Arduino card and environmental sensor potpourri is very cool.

The PCB design itself is great. It’s got a gigantic LED array, cutout for a wrist strap, and an onboard USB plug so you can program it just by sticking it in your computer; it shows up as a USB mass storage device when you plug it in. The files that show up on the “drive” are Micropython code that you can edit, save, and then run directly on the device. You can hardly beat that for convenience.

And there’s a full complement of sensors: not one but two temperature and humidity sensors, including our recent favorite BME280, which also reads barometric pressure. (We suspect that makes it a tri-corder.) There’s a real-time clock, a buzzer, and some buttons. Want to add more sensors? I2C ports are broken out for your convenience.

Besides having Star Trek flair, this board would give the various educational platforms a run for their money: Micro:bit, we’re looking at you. Very cool indeed!

Sci-Fi Contest: Both Wars and Trek Represented

Hackaday’s Sci-Fi Contest is in its third week. We’ve passed warp speed and were heading toward ludicrous speed. There is still almost a month to enter before March 6, when the deadline hits and everything goes to plaid. With 22 submissions all vying for 4 great prizes, there is still plenty of room for new challengers!

This contest is all about projects inspired by science fiction. There is a great mix of projects so far.

BB-8 Using Roll-On Deoderant

bb-8partsStar Wars is well represented with [Tech Flare’s] DIY Phone Controlled BB-8 Droid. [Tech Flare] is improving upon an existing BB-8 build. This is a low-cost build, so many of the parts are sourced from everyday items.

A new one for us is the 11 roll-on deodorant balls that are used as internal bearings. We’re not sure how well this robot will work, but it sure will be the best smelling BB-8 out there and you have to admit that is a creative use of easily source materials!

An Arduino is the brains of this Robot. As the title suggests, control comes from a smartphone. There is some creative work happening to fabricate the ball that makes up the body of the bot so be sure to jump in and check out that writeup.

LCARS In Real Life? Yes, Please!

lcarsAny Star Trek fan knows what the LCARS interface is [Elkentaro] is bringing LCARS life with LCARS NASA ISS Live Stream Viewer. [Elkentaro] is using a Raspberry Pi to display the International Space Station High Definition Eart-Viewing System (ISS HDEV) experiment.

The ISS is constantly streaming live views of the earth from one of 4 cameras. The Pi takes the stream and adds an LCARS image overlay. Everything is displayed on a 7″ TFT LCD. The same view Wesley Crusher would have seen at the helm of the NCC-1701D.

The overlay really brings the content to life and it has us thinking. If you have a refrigerator with one of those questionably-useful built-in montiors, it needs LCARS. Show us what you got!

Use the Schwartz

So what is missing from this contest? You of course! There is plenty of time left to create a great Sci-Fi inspired project. The deadline is Monday, March 6, 2017, 09:00 pm PST (+8 UTC). We dropped some Spaceballs references at the top of this article but haven’t actually seen an entry for that theme. Who’s going to build a voice-changing Dark Helmet?

Hackaday’s Sci-Fi Contest Hits Warp Speed

Hackers’ perspiration may go into soldering, coding, and building. For many of us, the inspiration for these projects comes from science fiction. The books, movies, TV shows, short stories, and comics we all grew up on, and continue to devour to this day. We’re paying homage to all these great Sci-Fi stories with our latest contest.

The Sci-Fi Contest isn’t about the most efficient way of building a 555 circuit or the tightest code. This one is about celebrating science fiction in the best way we know how — building awesome projects. This is Hackaday, so you’re going to have to use some form of working electronics in your entry. Beyond that, it’s up to you. Bring us your Overwatch cosplays, your Trek Tricorders, your Star Wars pod racers.

This isn’t our first Sci-Fi contest. In fact, Sci-Fi was one of’s first contests way back in 2014.
3 years and over 100,000 new hackers later, it’s time to take a fresh look at what you all have been up to. Projects that were entered in the first Sci-Fi contest are eligible, but you need to create a new project page and do some new work.

Check the rules for the full details. Once you’ve published a project use the drop-down menu on the left sidebar to enter it in the Hackaday Sci-Fi Contest.


Great work reaps great rewards. Here’s what we’ve got for this contest:

  • Grand Prize is a Rigol DS1054Z 4 Channel 50 MHz scope.
  • First Prize is a Monoprice Maker Select Mini 3D printer
  • Second Prize is a complete Blu-Ray box of Star Trek: The Next Generation
  • Third Prize is Lego’s latest rendition of the Millennium Falcon.

The deadline is Monday, March 6, 2017, 09:00 pm PST (+8 UTC), so don’t waste time! Warm up your soldering irons, spin up your warp drives, and create something awesome!

Bicycle-Powered Wimshurst Machine

A lot of great pieces of real technology were inspired (or, at least, look like) pieces of technology from science fiction of the past. Like the smartphones of today have a surreal resemblance to the Star Trek communicators of the 60s, [Steve] took inspiration from a story about a bicycle racing in space and set out to make his own.

In the story, the bicycle wheels are replaced by electrostatic generators that power a type of (fictional) ion drive. Since an ion drive wouldn’t add much thrust to a bicycle operated on the Earth, [Steve] used the electrostatic generator he built to create a sparking light show. The generator is called a Wimshurst machine and has two counter-rotating discs which collect charge. The charge is dissipated across a spark gap which is placed where the bike light would normally go.

We don’t know if the sparks from the Wimshurst generator are enough for a proper headlight, but it’s definitely a cool effect. [Steve] also points out that it might also work as a bug zapper, but either way you should check out the video after the break to see it in action! While it’s not quite a tricorder it’s still a pretty impressive sci-fi-inspired build, and something that’s definitely unique in the bicycle realm.

There’s quite a collection of these Wimshurst projects beginning to come together. Here’s one made using a trio of soda bottles, and another example which used 3D printing.

Walk Like A Xenomorph

[James Bruton] is busy working on his latest project, a “scrap metal sculpture”-inspired Alien Xenomorph suit.  However, he wanted to get a boost in height as well as a digitigrade stance. To that end, [James] 3D-printed a pair of customized stilts. Each stilt consisted of a lifter with several parts laminated together using acetone. He bolted an old pair of shoes onto the stilts, adding straps across the toes to keep the shoes from lifting up.

While the stilts worked very well, [James] wanted to add soles to them to give him some traction as he walked – falling while in a Xenomorph costume composed of sharp plastic sounds painful enough! He decided to hybrid print the soles using ABS and Ninjaflex. The ABS part of the sole was then acetone-welded to the bottom of the stilts.

[James] hopes to add some claws for effect, so long as they don’t impede his walking too much. He has already completed a good amount of the 3D-printed suit. We know the finished project is going to be amazing: [James] has created everything from Daleks to Iron Man!

Star Wars Training Droid Uses The Force

Star Wars Training Droid

We all know the scene, Obi-Wan Kenobi gives Luke a helmet with the blast shield down. He tells Luke “Your eyes can deceive you. Don’t trust them. Stretch out with your feelings!” Easy for Obi-Wan to say – he doesn’t have a remote training droid flying around and shooting at him. [Roeland] and his team are working to create a real-life version of the training droid for Hackday’s Sci-Fi contest.

The training droid in Star Wars may not have had the Force on its side, but it was pretty darn agile in the air. To replicate this, the team started with a standard Walkera Ladybird micro quadcopter. It would have been simple to have a human controlling the drone-turned-droid, but [Roeland and co] wanted a fully computer controlled system. The Ladybird can carry a small payload, but it just doesn’t have the power to lift a computer and sensor suite. The team took a note from the GRASP Lab and used an external computer with a camera to control their droid.

Rather than the expensive motion capture system used by the big labs, the team used a pair of Wii Remote controllers for stereo vision. A small IR LED mounted atop the droid made it visible to the Wii Remotes’ cameras. A laptop was employed to calculate the current position of the droid. With the current and desired positions known, the laptop calculated and sent commands to an Arduino, which then translated them for the droid’s controller.

Nice work guys! Now you just have to add the blaster emitters to it!
