A Meteorite Gift Box

[Justin Cole] was looking for the perfect birthday gift from for his wife. After some pondering, the answer fell from the sky in the form of a meteorite. The problem was how to present it. They don’t exactly make meteorite gift boxes, so [Justin] decided to build one of his own design. The box has a Russian space age theme reflecting the meteorite’s country of origin. The theme also made it a perfect entry for Hackaday’s Sci-Fi contest.

The gift box started life as an old steel film reel box. Some of us may still have boxes like this in our basements, protecting old 8mm family movies. [Justin] modeled the box in Solidworks, then added in his custom modifications. An angled walnut platform forms the stage. In the center of the stage is a 3D printed cone. The meteorite itself sits on a platform in the middle of the cone. A magnet keeps the iron meteorite in place.

A Neopixel ring provides indirect lighting below the meteorite. The ring is controlled by an Arduino, which also drives a couple of vibration motors. The motors create a hum in time to the changing colors of the ring. The whole package creates a neat way to present a rock from space.

We really like that [Justin] didn’t go over the top with sound effects, smoke, or bright lights. More importantly, [Justin’s] wife loved it, and couldn’t wait to share a video of the box with her friends.

It’s not to late to get in on the Hackaday Sci-Fi contest action. You have until Monday evening to enter your own creation.

Hackaday.io Passes 200,000 Registered Users

Hackaday.io just welcomed the 200,000th registered user! We are the world’s largest repository of open hardware projects and Hackaday.io is proving its worth as the world’s most vibrant technology community. This is where you go to get inspiration for your next project, to get help fleshing out your product ideas, to build your engineering dream team, and to tell the tales of the workbench whether that be success, failure, or anything in between.

Over the past six months, as we’ve grown from the 150k member milestone to this one, our movement has enjoyed ever-increasing interaction among this amazing group of people. Thank you for spending so much time here and making Hackaday.io a great place for everyone!

Hack Chat Bring Experts from Many Fields

bunnie03-01It’s always great when you can watch a conference talk or interview online. But if you weren’t there in person the opportunity for meaningful interaction has already passed. With this in mind, we’ve been inviting experts from numerous fields to host discussions live in the Hackaday.io Hack Chat room.

This is a great way to further our goal of forming a global virtual hackerspace. It’s common to have talks and workshops at a hackerspace, where you can not only learn from and ask questions of the person leading the event, but meet others who share your interests. This has happened time and again with recent guests including Bunnie Huang who talked about making and breaking hardware, a group of Adafruit engineers who discussed their work extending the MicroPython libraries, Sprite_tm who covered the continuing development of ESP32 support, and many more.

This Friday at Noon PST Hackaday’s own Jenny List will be leading the Hack Chat on RF Product design. See you there!

Amazing Projects

It’s pretty amazing to see a guide on building a smartphone for $50 in parts. If that exists anywhere, it’s probably on Hackaday.io — and it’s actually pushing about 80,000 views so far! Arsenijs is a regular around these parts and his ZeroPhone — a 2G communications device based on the Raspberry Pi Zero — is a project that he’s been updating as his prototype-to-production journey progresses. It has a big team behind it and we can’t wait to see where this one goes.

zerophone-thumbWorking on your own is still a great way to learn and we see all kinds of examples of that. Just4Fun is learning the dark arts that went into early personal computing with a $4 project to build a Z80 system on a breadboard.

We revel in the joy of seeing great hardware art come to life. FlipFrame is a great example; it’s a digital picture frame project that goes far beyond that simple description. It rotates the entire screen to fit the layout of the image while showing off all of the hardware that makes this possible rather than hiding it away inside a case.

In addition to our registered users milestone, we’re just about to pass our 20,000th published project. There are so many projects to celebrate and draw inspiration from, and that collection grows every day!

The Rise of Build Contests

This winter we’ve seen a ton of interest in the build contests hosted on Hackaday.io. Of course, nothing can compare to the reach of the Hackaday Prize, our worldwide engineering initiative that challenges people to Build Something That Matters. The 2016 winners were announced in November; even so, people have been tripping over themselves to get a project built for the numerous contests we’ve hosted since then.

enlightenpiOf note is the 1 kB Challenge — a contest dreamed up by our own Adam Fabio which challenged entrants to build an embedded project whose compiled code was 1 kB or less. It was a joy to dive into the entries for this and it will certainly return again.

Running right now is the revival of my favorite build contest: the Hackaday Sci-Fi Contest. Bring your favorite Sci-Fi tech to life — it just needs to be recognizable from a book, movie, or TV show and include some type of electronics.

Meet Your Friends in Real Life

Some of my closest friends in life were first met online. But eventually, you just want to hang out in the same room. This is becoming more and more common with Hackaday.io. In November we celebrated our second Hackaday SuperConferece where hundreds of people who love hardware creation gathered in Los Angeles for two days of amazing talks, workshops, and hands-on hacking challenges. This is a good one to add to your calendar but tickets do sell out so consider some other options.

We have regular meetups in LA and New York. If you are ever traveling there, make sure to look up the schedule and see if it can be part of your trip. Perhaps the most interesting was World Create Day. In 2016, we had 80 groups across the world plan meetups on the same day so that the Hackaday community could hang out in real life. We’re not ready to share the details quite yet, but you should plan for that to happen again this year. Something to look forward to!

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 Hackaday.io’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.

Prizes

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!

1 kB Challenge: And the winners are…

The 1 kB Challenge deadline has come and gone. The judges have done their work, and we’re ready to announce the winners. Before you jump down to find out who won, I’d like to take a moment to say thanks to everyone who participated. We had some incredible entries. To say that judging was hard is quite an understatement. Even [Eben Upton], father of the Raspberry Pi got in on the action. He created a new helicopter game for the classic BBC Micro. Look for writeups on the winners and many of the other entries in the coming weeks.

Grand Prize

brainfckThe grand prize goes to [Jaromir Sukuba] for Brainf*cktor. [Jaromir] went above and beyond this time. He created a computer which can be programmed in everyone’s favorite esoteric programming language. Brainf*cktor uses 1019 bytes of program memory in [Jaromir’s] PIC18F26K22. You can write, execute and edit programs. [Jaromir] ran into a bit of a problem with his LCD. The character tables would have thrown him over the 1 kB limit. Not a problem – he designed his own compressed character set, which is included in the 1019 bytes mentioned above. All the clever software takes physical form with a homemade PCB, and a case built from blank PCB material. Best of all, [Jaromir] has explained his software tricks, as well as included a full build log for anyone who wants to replicate his project. All that hard work will be rewarded with a Digi-Comp II kit from EMSL.

First Prize

mosFirst prize goes to [Dumitru Stama] with M0S – CortexM0 RTOS in 1024 bytes. Operating systems are complex beasts. Many of our readers have toyed with the Linux Kernel. But writing a real-time OS from scratch? That’s quite an undertaking.  [Dumitru] didn’t shy away from the challenge. He designed a Real-Time Operating System (RTOS) for ARM processors, written completely in ARM thumb assembly instructions. This is no bare-bones executive. M0S has a rich list of features, including preemptive task scheduling, mutexes, and inter-process communication. [Dumitru] even gave us memory allocation with an implementation of malloc() and free(). The OS was demonstrated with a NUCLEO-F072RB board from ST-Micro.

[Dumitru] didn’t just drop a GitHub link and run. He documented M0S with seven project logs and a 37-minute long video. The video uses electronic whiteboard drawings to clearly explain all the internal workings of the operating system, as well as how to use it.

[Dumitru] is the proud new owner of a Maker Select 3D printer V2!

Second Prize

1klaserSecond prize goes to [Cyrille Gindreau] with 1K Challange Laser. Vector lasers generally take lots of memory. You have to manage galvanometers, laser drive, and perform all the magic it takes to convert a set of vectors to lines drawn in space. The project uses 912 bytes of program and initialized data memory to command an MSP430 to draw an image.

Proving that flattery will get you everywhere, [Cyrille] picked the Hackaday logo as the subject. The Jolly Wrencher is not exactly simple to convert to vector format, though. It took some careful optimizations to come up with an image that fit within 1 kB. [Cyrille] wins a Bulbdial Clock kit from EMSL.

Third Prize

tinygamesThird prize goes to [Mark Sherman] with tinygames. Video games have been around for awhile, but they are never quite this small. [Mark] coaxed the minuscule Atmel ATtiny84 to play Centipede with only 1024 bytes of program memory. Even the BOM is kept small, with just a few support components. Control is handled by an Atari 2600 compatible joystick. Video is black and white NTSC, which is demonstrated on a period accurate CRT. [Mark] generates his video by racing the electron beam, exactly the same way the Atari 2600 did it.

[Mark] will take home a Blinkytile kit from Blinkinlabs.

Final thoughts

First of all, I’d like to thank the judges. Our own [Jenny List], [Gerrit Coetzee], [Pedro Umbelino], [Bil Herd], and [Brian Benchoff] worked hard with me in judging this contest. I’d also like to thank our community for creating some amazing projects. The contest may be over, but these projects are now out there for others to build, enjoy, and learn from.

I’ve wanted to organize this contest since [Jeri Ellsworth] and [Chris Gammell] took on the 555 contest way back in 2011. The problem is creating a set of rules that would be relatively fair to every architecture. I think 133 entries to this contest proves that we found a very fair set of constraints. It is safe to say this won’t be the last 1 kB Challenge here at Hackaday, so if you have ideas for future editions, share them in the comments!

Step Up to the 1 kB Challenge

1 kilobyte. Today it sounds like an infinitesimally small number. Computers come with tens of gigabytes of ram, and multiple terabytes of storage space. You can buy a Linux computer with 1 gig of RAM and secondary storage as big as the SD card you throw at it. Even microcontrollers have stepped up their game, with megabytes of flash often available for program storage.

Rapidly growing memory and storage are a great testament to technology marching forward to the beat of Moore’s law. But, we should be careful not to forget the techniques of past hackers who didn’t have so much breathing room. Those were the days when code was written in assembly. Debugging was accomplished with an expensive ICE (an In Circuit Emulator… if you were working for a big company), or a few LEDs if you were hacking away in your basement.

To keep these skills and techniques in play, we’ve created The 1 kB Challenge, a contest where the only limit is what you can do with 1 kB of program memory. Many Hackaday contests are rather loose with constraints — anyone can enter and at least make the judging rounds. This time 1 kB is a hard limit. If your program doesn’t fit, you’re disqualified, and that is a challenge worth stepping up to.

That said, this is Hackaday, we want people to be creative and work around the rules. The important thing to remember is the spirit of the design constraints: this is about doing all you can with 1 kB of program space. Search out the old and wise tricks, like compressing your code and including a decompression program in your 1 kB. Crafty hacks to squeeze more into less is fine. Using the 1 kB as a bootloader to load more code from an SD card is not fine.

Prizes

Any Hackaday contest needs some awesome prizes, and this one is no different.

Enlightened Raspberry Pi Contest Winners

The Enlightened Raspberry Pi Contest wrapped up last week. As soon as the contest closed, Hackaday’s crack team of judges jumped on the case. Every entrant was carefully reviewed.  This was no easy feat! The field of 168 projects included both new concepts and old favorites. All of them were designed, built and documented with care. After all the votes were counted, 8 finalists rose to the top and were sent to [Matt Richadrson], [Ken Shirriff], and [Alvaro Prieto], our VIP judges, for the final ranking.

Each and every project creator deserves recognition for not only building an awesome project, but documenting it on Hackaday.io so others can build, modify, and enjoy their own versions. Without further ado, here are the winners of the Enlightened Raspberry Pi Contest!
