Friday, February 7, 2014 - 19:10STEM Kits for Preschool and Kindergarten
Check out these STEM Kits for Preschoolers and Kindergarteners from hatch early learning:
The U.S. Department of Education began the STEM federal initiative for preschool in 2011. There are no greater natural scientists and engineers than young children; they are inquisitive and naturally learn as they play. Our STEM learning center, the lessons in the Activity Guide, and the materials in this Kit provide children with structure to build upon their natural inclination to explore, to build and to question. To learn more visit our blog post by Hatch expert, Jenne Parks…
…For each kit the activities are scaffolded, presenting information and ideas with increasing complexity to give children an introduction to the basic concepts of technology and promote literacy and other school readiness skills along the way. Each kit also comes with unlimited access to video-based online courses to help your teachers make the most of the kit in the classroom.
Friday, February 7, 2014 - 19:00Hackaday Retro Edition: Retro Roundup
Inspired by the Palm Lifedrive in the previous retro roundup, [Bobby] dug out his Palm TX and loaded up the retro edition with the Blazer browser. Given this device has WiFi and a browser, it’s not much, but [Bobby] did run in to a bit of a problem: Palm never released WPA2 for personal use, and this device’s WPA abilities are buried away in a server somewhere. Interesting that a device that’s relatively young could run into problems so easily.
How about another Palm? [nezb]‘s first smartphone, back in 2003, was a Treo 600. He dug it out, got it activated (no WiFi), and was able to load the retro edition. Even the Palm-optimized edition of Slashdot works!
How about some Xenix action? [Lorenzo] had an Olivetti 386 box with 4MB of RAM with Xenix – Microsoft Unix – as the operating system. The connection was over Ethernet using a thinnet card. Here’s a video of it booting.
[Eugenio] sent in a twofer. The first is a Thinkpad 600, a neat little laptop that would make for a great portable DOS gaming rig. It’s running Mandrake Linux 9, his very first Linux. Next up is the venerable Mac SE/30 with a Kinetics Etherport network card. It’s using a telnet client to talk to a Debian box.
Here’s one that was cool enough for its own post: [Hudson] over at NYC Resistor salvaged an old Mac SE with a BeagleBone Black connected to the CRT. This effectively turns the SE into a modern (if low powered) ARM Linux box. Emulators are always an option, though, as is loading our retro edition in xterm.
Links to the pics below, and you’re always welcome to dust off your old boxxen, fire it up, and load up the retro edition. It’s new and improved! Every half hour or so, five classic hacks from the first 10,000 Hackaday posts are converted to pure HTML. Take a pic and send it in.

Friday, February 7, 2014 - 17:21The Michelangelo of Lego Who Quit Law to Play With Toys
Kevin Fallon’s profile of Nathan Sawaya in the Daily Beast chronicles the famed lego artist’s transition from corporate lawyer to a mini-brick laying specialist with an eye for re-imagining iconic paintings:
While still working at his law firm, Sawaya would post his finished Lego sculptures on a website, brickartist.com. Soon, he was getting commissions to create custom pieces. Then requests started pouring in from all over the world. One day his website crashed because it was getting so many hits, he says, “so I left the law firm to play with toys full time.”
It wasn’t an easy transition. His colleagues and his family thought he was out of his mind. Quit corporate law to play Lego … can you blame them? Other reactions ran the gamut. “Some of my colleagues were jealous because I was following my passion,” Sawaya says. “Others were just confused.” But even after making the decision, it wasn’t all child’s play (heh) to go from the lifestyle of a lawyer making six figures to the lifestyle of an artist, unsure of whether he can pay rent each month.
“In 2007, I got my first solo show,” Sawaya remembers. “At the time I thought it was going to be my last solo show.”

Friday, February 7, 2014 - 16:59MakerBot Stories | How Architects Can Build a City of Ideas
Buildings designed today may not open for a decade, so architects make models to help people understand the future. Before presenting ideas to the clients, governments, and communities who must buy into (and pay for) their vision of the future, architects need to envision it themselves, through sketches, computer renderings, animations, and physical models.
“The earlier you can look at a physical object, the sooner you can understand a building and also make better design decisions,” says W Scott Allen, an associate architect and designer for Perkins+Will, a global architecture firm that has seven MakerBot Replicator 2 Desktop 3D Printers in its offices.
On a recent morning, Allen set out more than 40 six-inch towers on a conference room table at the global architecture firm’s New York office. The towers, process models used to reimagine the space around the Bernardine Monastery in Lviv, Ukraine, ranged from thin spires to fat blocks to something resembling a stack of old Life Savers. “You might have an entire set of models that are exceptionally functional and some that are wildly impractical but just look really awesome,” said Allen, who made these models on a MakerBot Replicator 2.
Rapid prototyping “profoundly changes our own creative process,” says Allen, who will set up the 3D printer before going home for the evening, returning the next morning to analyze the models with his colleagues. Then Allen will go back to the computer and generate new designs for the next night’s print run.
“Making all of these on the MakerBot frees us up to test more ideas for clients and come at a nicer solution in the same timeframe,” says Allen. The great thing, he adds, is that “you can almost print at the same speed that you can draw.”
Friday, February 7, 2014 - 16:38Program a Yún without writing code! Temboo’s Sketch Builder
Today’s guest blogger Vaughn Shinall from Temboo‘s team updates us with a new feature to ease your way into smart homes.
Choose your sensor, choose what action you want it to trigger, and voila–your Arduino Yún is doing it. Sending texts when a light sensor detects night, logging temperature data to a Google spreadsheet while you’re away, calling you when it sees an intruder in your home.
With our new Sketch Builder you can program your Yún to do all these things and more in no time. After choosing from multiple sensor types and actions, you can set the conditions and pins for your set up and have the code generated in an instant right on Temboo’s website. Then it’s just a simple copy-paste-upload job, and you’re on your way.
Go give the Sketch Builder a try today. Support for more sensor types and actions are on the way, so let us know what you’d like us to add.
Watch the Sketch Builder in action:
PS – You should also check out this cool Arduino Yún project where the user managed to get Temboo running straight from the board’s Linux distribution by installing the Temboo Python SDK on the Yún.
Friday, February 7, 2014 - 16:01Thumbs-Down Songs on Pandora with Your Mind
[Steven] likes music. Like many of us, he uses Pandora to enjoy the familiar and to discover new music. Now, Pandora means well, but she gets it wrong sometimes. [Steven] has had a Mindwave Mobile EEG headset lying around for a while and decided to put it to good use. With the aid of a Raspberry Pi and a bluetooth module, he built a brainwave-controlled Pandora track advancing system.
The idea is to recognize that you dislike a song based on your brainwaves. The Mindwave gives data for many different brainwaves as well as approximating your attention and meditation levels. Since [Steven] isn’t well-versed in brainwavery, he used Bayesian estimation to generate two multivariate Gaussian models. One represents good music, and the other represents bad music. The resulting algorithm is about 70% accurate, so [Steven]‘s Python script waits for four “bad music” estimations in a row before advancing the track.
[Steven] streams Pandora through pianobar and has a modified version of the control-pianobar script in his GitHub repo. His script will also alert you if the headset isn’t getting good skin contact, a variable that the Mindwave reports on a scale of 0 to 200.
Stick around for a demo of [Steven] controlling Pandora with his mind. If you don’t have an EEG headset, you can still control Pandora with a Pi, pianobar, and some nice clicky buttons.
Friday, February 7, 2014 - 16:00Colossus On A Raspberry Pi @Raspberry_Pi #PiDay #raspberrypi
Wednesday was the 70th Anniversary of Colossus, the world’s first programmable computer. In honor of that, we found this project from a couple years back by mr pj evans, replicating the work of Colossus. He has a tutorial up on the site so you’ll be able to make one yourself as well!
Like many oldies who ordered a Raspberry Pi, I was more taken that such a thing now existed rather than having any kind of specific plans for it. Never mind, I thought, something will come along. Sure enough it did. A little background first.
In 2007, Tony Sale and the volunteers at The National Museum of Computing at Bletchley Park had completed their magnum opus: The rebuild of Colossus. This saw a major milestone after many years of works by the team as they toiled to recreate the world’s first programmable computer in as authentic a fashion as possible…
A rebuilt Colossus partakes in the ‘Great Cypher Challenge’. A Lorenz cypher machine was taken to the Heinz Nixdorf museum in Paderborn, Germany. Over the course of a day, messages were enciphered using the device and transmitted over teleprinter code (‘non-morse’) just as they were in WWII. In Bletchley, modern-day ‘Y’ station operators listened in on old radio sets trying to record the signal. At about 3pm, a clear message was received and Colossus was set to work. A few hours later, and with a little help from it’s modern-day codebreakers, all twelve rotors settings for Lorenz had been found and the message decrypted. Champagne everywhere.
In Bonn, a young cryptology enthusiast by the name of Joachim Schueth was also listening (fair enough, the competition was open to anyone). He had written some software that would not only act as an analogue for Colossus’ work (identifying the first five rotor settings) but would in fact handle the entire process from interception to revealing the plaintext message. He intercepted the message first time and had an answer 46 seconds later.
Jo has been kind enough to allow others to download his code, along with recordings of all three messages he intercepted, along with generous instructions on how to proceed. So, there was my first Raspberry Pi challenge, could it become a modern-day Colossus? It seemed appropriate after all, to see this little wonder of 2012 pit itself against it’s Granddad.
After a few tweaks I was able to get the whole process up and running on Eben and David’s little baby. Yes, the Raspberry Pi, running the standard Debian ‘Squeeze’ image, can not only replicate Colossus’ work but the whole process from interception to plaintext. Let’s call it Pilossus.

Friday, February 7, 2014 - 15:32Enchanting Galadriel Costume
Galadriel, Lady of Lothlórien, has an ethereal look. It’s distinctive and hard to capture without visual effects and special lighting. The key is getting the costume and hair right before any faux sparkles are added, and cosplayer Áli did a wonderful job creating the elvish ensemble. Here’s what she had to say about making the costume:
“Galadriel is one of my favourite female characters. The strength and power she yields, all under grace, I find inspiring. Galadriel means so much to me that I wanted to make sure that every aspect of this costume was made with care so I took a couple months to make it. The ‘bones’ of the gown were taken from a pre-existing wedding dress that I found at a thrift shop. I liked the idea that once upon a time someone wore this dress on a very important day in her life, so I carried that feeling into my Galadriel costume. I took the pre-existing dress apart and redid the structure to suit the change in waistline and then added the leaf patterned lace on top of it. After the gown was done I hot fixed 4000+ rhinestones, following the leaf pattern on the lace and made the crown and brooch from worbla.”

Friday, February 7, 2014 - 15:01Selfie! The Earth as Seen from Mars…
A view of Earth from the surface of Mars. More via JPL (including hi-res images):
This view of the twilight sky and Martian horizon taken by NASA’s Curiosity Mars rover includes Earth as the brightest point of light in the night sky. Earth is a little left of center in the image, and our moon is just below Earth. Two annotated versions of this image are also available in Figures 1 and 2.
Researchers used the left eye camera of Curiosity’s Mast Camera (Mastcam) to capture this scene about 80 minutes after sunset on the 529th Martian day, or sol, of the rover’s work on Mars (Jan. 31, 2014). The image has been processed to remove effects of cosmic rays.
A human observer with normal vision, if standing on Mars, could easily see Earth and the moon as two distinct, bright “evening stars.”
Friday, February 7, 2014 - 15:008086tiny: a free PC XT-compatible virtual machine/emulator written in C
PC XT-compatible virtual machine/emulator written in C created by Adrian Cable, via RaspberryPi.org:
“The personal computer as we know it today began in the early 80s with the release of the IBM PC – an incredibly complex machine for its time, and the result of hundreds of thousands of man-hours of development time, at a cost of hundreds of millions of dollars.
Thirty years later, I set out to answer the question of how small a highly portable, software PC emulator/virtual machine could be written, complete and accurate enough to simulate not just the Intel 8086 CPU but enough of the peripheral hardware to run software like Windows, AutoCAD, Lotus 1-2-3 and classic PC games. The answer: 4043 bytes of highly condensed C source code, which won the 2013 International Obfuscated C Code Contest.
Following the contest, widespread demand led to the release of 8086tiny, a fully documented and commented distribution of the original code, including full BIOS source code. 8086tiny, when deployed on the $25 Raspberry Pi, produces not only the world’s smallest but also the world’s cheapest PC.
Uniquely we believe for PC emulators, 8086tiny is released under the most free open source license possible, the MIT License, allowing use or redistribution for any purpose, commercial or non-commercial, with no restrictions whatsoever. I encourage anyone to use 8086tiny as a starting point for their own emulation projects.”

Friday, February 7, 2014 - 14:00Tweeting with Python tweepy on the Raspberry Pi #piday #raspberrypi @Raspberry_Pi
So in this post, which is part 2, I’m going to show you how to post a tweet using a Python program on the Raspberry Pi.
Create Your Twitter App
Give Your App Permission to Write
Then make your app read/write. You won’t be able to tweet unless you give it permission to write. Newly created apps are read-only by default. Click on the settings tab and scroll down until you see this…
Give your app Read and Write permissions
…then make sure that Read and Write is selected. Then click “Update this twitter application’s settings“.
Install Tweepy (if you haven’t already)
Here’s how you install tweepy.
Now We’re Ready to Code
A lot of our code from last time can be re-used. But if you’ve created a new app, or changed the permissions on an old one, you might have to create new ‘Access tokens’….
