    This Tiny Arcade Machine Holds a Raspberry Pi @Raspberry_Pi #piday #raspberrypi

    This tiny desktop arcade is fully functionally thanks to a raspberry pi, from eetimes.

    For many of us, there is a certain wonderful feeling that bubbles to the surface when we think of arcades. The many hours spent huddled around a game, pouring our hard-earned quarters into the machine. The shouts of frustration as your friends can’t beat your high score. The ridiculously sore fingers from mashing those buttons for far too long. Unfortunately, recapturing even a bit of that fun is difficult.

    Steve Smith managed to come up with a great way to recapture a bit of his arcade fun. He decided to put an arcade cabinet on his desk. This itty-bitty arcade machine you see is fully functional and loaded with games. Housed inside the tiny cabinet is a Raspberry Pi loaded with Mame, an emulator for a game system.

    This specific version of Mame is called PiMame and can emulate several different video gaming systems. You can find more information on PiMame here, if you want to run it on your Raspberry Pi.

    Make an inexpensive wi-fi enabled media center for your car using Raspberry Pi! #piday #raspberrypi @Raspberry_Pi


    MAKE has a great new tutorial up for a Raspberry Pi powered car computer.

    I have always loved those old TV series with futuristic tech in those futuristic vehicles, like Knight Rider, Airwolf, and Street Hawk. So it got me thinking about how easy it would be to add a computer to a vehicle. Now I know it’s been done before, and a quick Google search shows multiple companies making very complex vehicle computers, but at a large cost.

    Well, I thought, my Raspberry Pi is the perfect device for this.

    • It’s cheap
    • It’s very small
    • It’s got small power requirements (runs off a micro USB car charger)
    • It’s got flexible video and audio outputs (HDMI and Composite RCA for video, HDMI and 3.5mm audio jack for audio)
    • And best of all, you can change operating systems by simply switching out SD cards.

    Below is a photo of the Raspberry Pi running the excellent media center-type operating system Raspbmc which is perfect for browsing and playing your media collection using a media center remote or something similar, as shown in the Parts list.

    Tutorial – Adafruit 1-Wire GPIO Breakout – DS2413. Running out of pins on your Arduino? Get this!

    Microcontrollers 1551 Lrg

    Tutorial – Adafruit 1-Wire GPIO Breakout – DS2413 @ Adafruit Learning System.

    Pins are precious in the microcontroller world. How many times have you needed just one more pin? Sure, you could step up to a Mega and get a whole bunch more, but what if you really just need one or two? The DS2413 breakout board is the perfect solution. Each DS2413 breakout has 2 open drain GPIO pins and a 1-Wire interface. Just one of these boards will give you 2 pins for the price of one. But you can keep expanding from there.

    You can put as many of these boards as you want on the the 1-wire bus and still control all of them with just one Arduino pin. Each chip has a 48-bit unique address, which means (in theory*) you could have as many as 2 * 2^48 pins controlled by just one Arduino pin! What could you control with 562 trillion pins?

    How to – Automatic monitor color temperature adjustment… DIY f.lux @JustGetFlux

    Light Rwrzevc

    How to – Automatic monitor color temperature adjustment @ The Adafruit Learning System.

    Staring at a computer monitor all day is quite stressful. Moving your gaze from the cold, white light of a monitor to warmer indoor light is especially jarring to your senses. Programs like f.lux and Redshift were created to ease this strain by adjusting the color temperature of your monitor. However these programs don’t measure color temperature of light in the environment and instead guess the temperature based on location, time of day, and sunrise/sunset time.

    This project will show you how to build hardware that measures the temperature of ambient light and automatically adjusts your monitor color to match. With just a simple RGB color sensor and an Arduino or FT232H-based cable, your computer can easily sense and react to light in its environment.

    Before building this project, it will be helpful to familiarize yourself with the color sensor guide.

    NEW PRODUCT – Large Enclosed Piezo Element w/ Wires


    NEW PRODUCT – Large Enclosed Piezo Element w/ Wires: This large (30mm diameter) piezo element is nicely enclosed with mounting holes so you can attach easily. Piezo elements convert vibration to voltage or voltage to vibration. That means you can use this as a buzzer for making beeps, tones and alerts AND you can use it as a sensor, to detect fast movements like knocks. You can also use it under a drum pad to make a drum/crash sensor.

    It’s rated for up to 12Vpp use but you can also use 3 or 5V square waves and its plenty loud. For music use with an Arduino, check out the Tone tutorial. For sensing, the Knock tutorial is your guide! There are thin wires attached, we plugged them into a solderless breadboard, but they might too thin to plug in directly into the Arduino socket headers.

    Hackaday’s Guide to Shanghai

    We happened to be in Shanghai for Electronica trade fair this year and had a great time exploring heavy industrial gear and fantasizing about all the things we could do with it. However, we simply couldn’t ignore the fact that there was a whole city out there that we’re completely missing out on. So after less than a day of being surrounded by businesspeople and Miss Universe-dressed promoters, we decided to pack our bags and hit the streets.

    The question was, where should we go? Finding interesting things in a city that keeps shapeshifting (the whole Shanghai skyline did not exist 20 years ago) can be a challenge. Fortunately, our friend [David Li] gave us a list:

    1. Xin Che Jian
    2. Jiu Xing market
    3. Beijing Lu electronic market
    4. Qiujiang Lu CNC/lasercut market
    5. DFRobot.com

    …and off we were.


    The Country’s First Hackerspace

    053b2694af6111e3a7fd12b201d372bb_8Xin Che Jian is China’s first hackerspace, founded in 2010 by [David Li] and is currently based in Downtown Shanghai, Xuhui district. [David] is being modest in saying that the reason behind founding Xin Che Jian was not changing the world, but rather a simple fact that his wife wanted to throw out all the hardware junk he’s been piling up in the apartment and he needed a place for it. The reality is that this place has completely transformed the ‘Maker’ scene in China (term “Hacker” is rarely used on the other side of the Great Firewall). Inspired by this example, people have started opening up spaces in different cities and the whole thing is starting to reach scary proportions with government stepping in, creating “makerspaces” in schools and providing TV coverage.

    We happened to be there on a rainy Wednesday night, and the whole place had an irresistible Bladerunner feel to it. Walls of cardboard boxes, hydroponics tent, tons of electronics and all sorts of people ranging from local makers to expat “new media” artists. The night we visited was “open night” and we got to hear a lot of interesting and diverse talks. Talk topics had a very wide range. One discussed using Max/MSP to generate sound corresponding to the time lapse camera recordings of the space. Another slightly bizarre demonstration outlined the importance of insulation when dealing with high voltages, which among other things, included “spark frying” of something that moves.


    Shopping for Electronics

    Next stop was Beijing Lu electronics market. This one is a dream — a five-floor superstore exclusively selling electronics components. It’s a farmer’s market for silicon. We have learned that a lot of these shops are actually brick-and-mortar fronts for stores on TaoBao, but here you can buy things first hand, with a personal touch from “your guy”. If you happen to live in Shanghai, you can get components delivered the same day, pizza-style: by carrier on scooter.

    Surrounding streets are even better. It’s where you can buy metal, plastic, get stuff cut, folded, CNC’d or spot-welded right on the curbside. Big blocks of steel, iron, aluminum all cut to order by artisans with decades of experience. For makers, artists and hackers this is where a lot of the real jewels lie. For an extra dystopian flavor, you can enjoy the fact that, among rows of such shops, you can find things like food stands, cleaners and grocery stores. You can get your aluminum cut in one shop and get your nails done nextdoor.

    And now for something completely different..


    Small Business Catering to Makers

    DFRobot is something you would not ordinary expect in China. It’s offices look & feel like a proper Silicon Valley startup; it’s engineers are young, passionate and big on Open Hardware. They have great ideas and build beautifully designed products targeting the DIY community, educators and researchers. Their goal is “bringing back the joy of thinkering to daily life” – still a radical concept in China. If I were Adafruit or Sparkfun, I would watch out for these guys.

    We got to hang around their office and saw a lot of great projects, but the experience we enjoyed most was in the 3D Printer room. We came into this room only to find a couple of dozen 3D printers, all printing bones! Some professor ordered a couple of hundred human bones for him to use in some kind of kinetic art installation. Weird.

    For more in-depth look on Maker culture and it’s intersection with industry development in China, check out our attempt at serious investigative journalism in an interview with the fantastic [Silvia Lindtner], researcher at Fudan University.

    Students Design Automated Pill Dispenser @Raspberry_Pi #piday #raspberrypi


    Dalrida School Designs Automated Raspberry Pi powered pill dispenser. via Dan Grabham

    Winning the secondary school category, this entry stood out amongst some outstanding projects in the category. The judges said it demonstrated good use of the hardware and software as well as showing superb team work. Remembering to take the right number of pills at the right time can be stressful, particularly for those who are elderly or very sick. This automated pill dispenser makes managing medicine easier: the Raspberry Pi connects a pill dispenser with the person’s GP, who can program the administration of the drugs through a website. Correct dosages drop out of the Raspberry Pi controlled pill dispenser at the specified times. Meanwhile, if sensors detect pills haven’t moved once dispensed, an alert is sent to a family member who can remind them.

    MakerBot Desktop | From Digital to Physical

    MBD Education Blog pt2_Header 3

    Steps to Success
    Every now and then we’re reminded 3D printing is not science fiction, but a real technology used every day to make amazing things in homes, studios, schools, and businesses. At MakerBot we’re proud to be leading this Next Industrial Revolution with the MakerBot 3D Ecosystem, which makes desktop 3D printing and 3D scanning affordable and reliable for everyone, and includes a variety of products and services to help unleash your creativity.

    One of the newest members of our family is MakerBot Desktop, a complete, free 3D printing solution for discovering, managing, and sharing your 3D prints. As we learned in last week’s post on connectivity, MakerBot Desktop was built to access the powerful software capabilities of the new Fifth Generation line of MakerBot Replicator Desktop 3D Printers. This week, we’ll take a look at how to use it to go, in just three simple steps, from a 3D design to a 3D print.

    1. Find a Model
    Whether you make your own digital 3D models or prefer to use ones that are already made, MakerBot Desktop gives you three ways to get started:

    – Did you design your own model? MakerBot Desktop will open any STL or OBJ file. Just make sure you save your file as one of those types in the design software you’re using. Click Add File in MakerBot Desktop, and navigate to where the file is saved on your computer.

    – Want to browse through free designs? Click on Explore in MakerBot Desktop to see the hundreds of thousands of 3D printable things on MakerBot Thingiverse, the 3D design community for discovering, printing, and sharing 3D models. Simply click Prepare next to the file name, and MakerBot Desktop will open up the file in the Prepare tab.

    – Looking for high-quality, original prints? Check out the MakerBot Digital Store by clicking Store in MakerBot Desktop. Buy individual models or collections, all designed by our experts. A print file for your purchased model will appear in your MakerBot Cloud Library.


    2. Prepare Your Model
    Once you have your model open in the Prepare tab you can change its orientation, scale it up or down, or even add another model to the virtual build plate.


    You may also want to change some settings before printing. Click Settings and choose if you want to print with a raft, support, or both. A raft is a base on which your model will be printed, and can help it stick to the plate. Supports can be printed to hold up overhanging parts of your model. Both the raft and supports can be easily removed once the print is finished.

    You can also choose your resolution: low, standard, or high. The higher resolution, the longer the time it will take to print. For more information on preparing your model, visit MakerBot Desktop Advanced Options page in the MakerBot support website.


    3. Send the File to Your MakerBot Replicator
    When your model is set up the way you like it, you can go ahead and click Print.

    – If you’re printing via USB stick, MakerBot Desktop will slice your file when you click Print. When the file is ready, click Export Now, and save the file to your USB stick. Then plug the USB stick into the port on the MakerBot Replicator, and navigate to USB Storage on the LCD Display. Find your file and push the control panel dial to print.

    – If you’re printing via USB cable, LAN, or Wi-Fi (coming soon!), MakerBot Desktop will slice your file and send it over to your MakerBot Replicator when you click Print. All you have to do is press the control panel dial to confirm and start the print.

    Show the World Your Work
    If you printed a file from Thingiverse, MakerBot Desktop will prompt you to share a photo of your print. Select Share to Thingiverse, and the MakerBot Replicator’s on-board camera will take a photo of your build area. Push the dial again to post the photo to the Thing page.


    Now you’re all set to start printing. Go ahead and explore all the exciting options MakerBot Desktop offers with your new MakerBot Replicator. And stay tuned next week for when we’ll go over how to use the MakerBot Cloud Library!

    New Product Friday: There is no Spoon

    We’re back, as always, with more new products for you. This week we just have a few, but one of them is mind control, so we’ve got that going for us. Be sure to check the video.

    This really is the future, isn’t it? Put something on your head, load an app on your phone, and see your brain waves. It’s a great time to be alive.

    alt text

    The Neurosky Mindwave Mobile an EEG headset that safely measures and transfers the power spectrum (alpha waves, beta waves, etc.) data via Bluetooth to wirelessly communicate with your computer, iOS or Android device. We even have a cool hacking tutorial from one of our hackers-in-residence. It’s a pretty cool way to play with brainwaves and such.

    alt text

    These long headers work well when you want to connect something in a breadboard. Because they’re centered (the pins on both sides of the plastic strip are of equal length), they fit into a breadboard snugly, and leave you enough pin length to connect female headers. These also work well for connecting two female headers together, like servo cables and such. They come in 40-pin strips that are easily cut or snapped to length.

    alt text

    We have a new version of the RFM12. The new version, the RFM12BSP is slightly different, but ultimately has the same functionality as the previous module. These are great little transceivers for sending data back and forth. They’re SMD, but can easily be used with 2mm pitch headers. They work similarly to the RFM22, which we have on a shield.

    alt text

    Lastly, we have another header. This is a 10-pin female SMD header with 0.1" spacing. We carry numerous other pin configurations of this, but didn’t carry a 10-pin, so why not?

    That’s all I have for this week. I’ll be back again next week with more new products, and the final Robotics 101 video (Tools - Part 2). Be sure to check back then and thanks for reading and watching!

    Raspberry Pi Transformed Into Wearable Cyborg Tech @raspberry_pi #piday #raspberrypi


    Zack Freedman creates a wearable cyborg Raspberry Pi.

    When Rob Bishop of the Raspberry Pi Foundation visited the space yesterday, he challenged the attendees to build a project using the tiny open-source computer. I decided, why not take advantage of its small size to make myself a cyborg?

    Wearable technology is my main area of hacking, so I had some parts lying around. The wearable display uses the innards of a pair of MyVu Crystal video glasses – these are tricky to disassemble, so check this tutorial. You can cut off the earbuds and one microdisplay without breaking the functionality. I bent a coat hanger into a behind-the-ear mount, electrical-taped the parts in place, and viola, monocular HUD.


    The brains of the operation are, of course, a RasPi. I fitted it with a 2GB micro-SD card in the excellent Quilix pIO mini-adapter, Raspbian, a Duracell phone recharger, and a cheapo mini keyboard-trackpad combo. Apart from the video cable, the system is totally wireless! I zip-tied the RasPi to my belt and the keyboard to my wrist. Everything is wearable with zip ties!

    No one brought a wi-fi dongle, so no wireless intertubes. The upside is that when I wanted to go online, I could actually jack into an Ethernet port!

    I built this with parts lying around, but a similar setup would cost just over $100. Not bad for a fully-functional wearable computer, especially one with connectivity and around four hours of battery! Plus, ladies love a Pi in the Face. Maker ladies, at least.
