    New Product Friday: High Five For Wi-Fi

    Products, products, and more products. That’s what Fridays are all about here at SparkFun. We have a few new things this week. Check out the video and hear our engineer Shawn explain the new CC3000 shield and breakout board.

    I’m not kidding here: $50k for the first person to figure out how to harvest Shawn’s energy. I think the secret might be in his bow-tie. More research is necessary.

    alt text

    The CC300 is a handy little WiFi module from TI. This week, we are selling the bare module and a breakout board, as well as a shield. Pick your flavor. The module allows you to connect your project to a wireless network. It even has a clever little setup routine that enables you to configure the module for your network using your phone. So when you move the project from network to network, you don’t have to go in and reprogram the sketch. Nifty.

    alt text

    Looking for a bunch of sensors, but don’t want to throw down for the full sensor kit? Check out the new essential sensor kit. This kit includes a lot of our most popular sensors including a flex sensor, tilt sensor, hall effect sensor, force sensitive resistor, photocell, and more! It’s a great deal for beginners or anyone that just wants to start playing around with how microcontrollers interact with hardware.

    alt text

    We’ve been using double-sided foam tape for years to stick PCBs to enclosures. It works well, but sometimes you need something more, uh, industrial. Check out the foam PCB tape. This stuff is industrial grade foam tape for sticking things to other things. The ‘VHB’ stands for ‘very high bond’ (no, there’s not going to be a new 007 movie filmed in Denver). The tape is 1" wide and you get about a yard in length. Check the video above and you can see how strong it is.

    alt text

    People have been asking for us to carry the exact transistor that comes with the SIK. Sure. Here you go.

    alt text

    Lastly, there’s a new Beaglebone Black out this week. This isn’t shipping yet, we only have it for pre-order. This one is the ‘Rev C’ which is identical in every way, but has 4GB of onboard flash memory (instead of 2GB) and is $10 more. Keep in mind that Beaglebone plans to fill backorders on the ‘Rev B’ before the new ‘C’ starts shipping.

    That’s it for this week everyone. Thanks for watching, reading, and buying stuff. We’ll be back again next week with more new products, tutorials, and other things you might enjoy. See you then!

    Blinkenschild, The RGB LED Display For Every Occasion


    One morning [overflo] decided to protest the European Parliament’s stance on equine rights of defecation, a cherished liberty dating back to the time of Charlemagne. The best way to do this is, of course, blinking lights. He calls his project Blinkenschild, and it’s one of the best portable LED displays we’ve seen.

    The display is based around fifteen RGB-123 LED panels, each containing an 8×8 matrix of WS2811 LEDs. That’s 960 pixels, all controlled with a Teensy 3.1. Power is supplied by fifteen LiPo cells wired together in parallel giving him 6 Ah of battery life. Clunky, yes, but it’s small enough to fit in a backpack and that’s what [overflo] had sitting around anyway.

    The animations for the display are generated by Glediator, an unfortunately not open source control app for LED matrices. Glediator sends data out over a serial port but not over IP or directly into a file. Not wanting to carry a laptop around with him, [overflo] created a virtual serial port and dumped the output of Glediator into a file so it could be played back stored on an SD card and controlled with an Android app. Very clever, and just the thing to raise awareness of horse and Internet concerns.

    Video below.

    UPDATE: Check out [overflo's] clarification in the comments below.

    Quake III bounty: we have a winner! #piday #raspberrypi @Raspberry_Pi


    Quake III bounty: we have a winner! @ RaspberryPi.org Pi.

    At the end of February, Broadcom announced the release of full documentation for the VideoCore IV graphics core, and a complete source release of the graphics stack for the BCM21553 cellphone chip. To celebrate, we offered a $10k prize to the first person to port this codebase to the BCM2835 application processor that sits at the heart of the Raspberry Pi, and to get Quake 3 (which already runs on the Pi) running on the newly open ARM driver, rather on the closed-source VPU driver. Our hope was that the ported driver would be a helpful reference for anyone working on a Mesa/Gallium3D driver for VideoCore IV.

    I’m delighted to say that we have a winner. Simon Hall is a longtime Pi hacker, who also produced the first ARMv6-accelerated copies-and-fills library back in 2012 and wrote the DMA kernel module that we integrate in our Raspbian releases. The prize couldn’t have gone to a more fitting recipient.

    So, without further ado, here are Simon’s instructions for getting the driver up and running….

    pidart: An electronic dart board with superpowers #piday #raspberrypi @Raspberry_Pi

    Daniel Fett made this tricked out dartboard with tons of cool features- check out the all the details over at his blog!

    At our research group at the university, we play a round of darts every day during the lunch break. We used to use an cheap electronic dart board and entered the results manually into our “Dartabase” (“Dartenbank” in german). Obviously, this manual process is not very satisfying for a geek, so I created a Raspberry Pi driven electronic dart board (called, of course, “pidart”).

    I started out from a standard soft electronic dart board and disassembled it. Then, I connected the sensors in the board and the buttons to an Arduino Mega microcontroller. The Arduino sends the dart hits and button presses on the board to the Raspberry Pi, where the pidart software runs. The Pi shows the current score and other data on a screen connected via HDMI and provides a web interface to control the software. I will provide a bit more technical background below.


    The main feature of pidart is, of course, to keep track of the scores of each player and to enter the final results into our Dartabase. Apart from that, over the time, I added more features:

    • Skipping players: Sometimes, one of us takes a short break during the game or cannot attend the game from the very beginning. In this case, we can tell pidart to skip the player until he returns. The player can catch up the missed rounds later and even still win the game when the other players have checked out already (if he checks out in less rounds than them).
    • The same feature also allows for sequential games, where each player plays a full game straight and the players play after each other.
    • Text-to-speech: pidart uses a synthesized voice to give spoken comments for each throw of a dart.
    • Background music: pidart plays different background music depending on the game situation. You might know that music from somewhere…
    • Live ranking: Our Dartabase creates a ranking of the players based on the ELO system. The pidart software predicts the game’s outcome during the game and shows the new Dartabase ranking.
    • Web interface: Not only is a web browser the main GUI for pidart, it also allows for multiple clients to watch the current game in real time. Players can follow the game from anywhere (for example, on a smart phone).
    • Post-fact editing of results: If the board registered something wrong or someone accidentally touched the board, the last frame can be edited manually.
    • Adding and removing players dynamically: Players can leave the game (if they are allowed so by the other players ;-) ) and even join the game at any time without any disadvantage.

    Raspberry Pi UPS Using Supercapacitors


    What happens when you want to integrate a Raspberry Pi into some kind of project that gets turned on and off with mains voltage? Do you power the Pi separately, or make a UPS for it?

    [Lutz Lisseck] decided he wanted to turn his ambient-lamp (Rundbuntplasma) on and off with only the main power switch in his Hackerpsace. He could build a traditional UPS using a battery pack (it’s only 5V after all!) but decided to take it a step further. He picked up a pair of 50F supercapacitors. This way his UPS would last longer than his Pi would! The caps store just enough power that when the main supply is cut, a GPIO notices, tells the Pi, and it begins a shutdown sequence lasting about 30 seconds.

    While [Lutz] is using two 2.7V supercapacitors, he mentions it would be a lot cheaper to use a step-up converter instead of putting them in series — but he had the caps on hand so decided to use both.

    If you need it to last a bit longer, you could make one with rechargeable batteries…

    LightByte: Animated Shutters


    Here’s another interesting project to come out of the MIT Media Lab — it’s called LightByte, and it’s all about interacting with sunlight and shadows in a new, rather unorthodox way.

    We suppose its technical name could be a massive interactive sun pixel facade, but that’s a bit too much of a mouthful. What you really want to know is how it works, and the answer is, a lot of servos. We weren’t able to find an exact number but the hardware behind LightByte includes well over 100 servos, and a matrix of Arduinos to control them. While that is quite impressive by itself, it gets better — it’s actually completely interactive; recognizing gestures, responding to text messages and emails, and you can even draw pictures with the included “wand”.

    We love anything mechanical like this — it’s just something about mechanical shutters that make them so awesome. Of course, reverse-engineered flip dot displays are pretty cool too! Or massive home-made flip-dot displays like this one…

    [Thanks Alexander!]

    Some Tips About Tips


    Gather, boys and girls, while we take a moment to talk about submitting projects via the Hackaday Tips Line. Come across something really cool that you think deserves a mention on our page? Let us know about it! Did you yourself make something really cool? Tell us about that, too! It doesn’t matter if it’s a project that’s been sitting on some dark corner of the Internet for a few years. If we haven’t seen it yet, we want to.

    Don’t think your project is good enough for Hackaday? You’re probably too self-critical. We’re after hacks: it’s the idea that counts. Not polished? No problem. The only thing that needs to be complete is your description of the hack.

    Stick with us after the jump; we’ve got plenty of tips about tips to help you out.

    So you wanna get on the front page?

    The best project submissions answer these question:

    • What the heck is it?
    • What got you into this?
    • What’d you use?
    • Where’d you get that stuff?
    • How does it work?
    • What didn’t work? (Anything blow up?!)
    • What would you do differently?

    We don’t expect submissions to be a how-to guide with step-by-step instructions—though those can and usually are great—but this is your chance to show off: why not dump out some photos, videos, and links! The toughest projects for us to feature are emailed essays with a few attached photos. If you need a place to host your write-up, get busy documenting it on Hackaday Projects

    Titling your emails:

    Avoid vaguely titled emails and instead be clear about what you’re submitting.

    Bad Title: “I did this to my brother’s car…” Did you barf in it? C’mon, give us something attention-grabbing.

    Good Title: “Raspi Nav Unit for Car.” It’s clear, concise, and makes life easier for everyone.

    If the tip concerns a specific Hackaday Column, put that at the front of the title. Retrotechtacular, Fail of the Week, 3D Printering, Droning OnHacking and Philosophy, and Adventures in Hackerspacing are all recurring columns that are on the lookout for your content submissions. Help us keep them thriving by sending us tips that specifically fit those topics! Titles such as “Retrotechtacular Tip: 50′s Video on Bicycle Making” makes sorting a breeze!

    Tell us how to identify you if you have a preference:

    We want to credit your project and your work appropriately, which—if it’s something you have a preference about—is easier if you give us a heads up in the email. If you’d rather we use your handle, let us know you prefer to be called [snipehuntr] and not Jim-Bob. If the associated pronouns aren’t obvious, let us know those too. It is also helpful when you tell us: “this isn’t my project, but I thought it belonged on Hackaday.”

    If your project wasn’t chosen:

    Let’s face it, some projects don’t make it to the main page. Sometimes we pass on things because it’s poorly presented, and sometimes it slips through the cracks. Sometimes it’s…a press release. Ugh. Don’t send us those.

    If you’ve submitted in the past and didn’t get featured, we don’t want to discourage you from submitting again. See if you can spruce it up with some of the above advice then hit us up again. There’s no harm in resubmitting every once in awhile.

    So. Now there’s no excuse. Click that tips link and blow it up!

    Building the Rocketeer’s Helmet

    rocketeer helmet

    The Rocketeer has a special place in many of our memories, and Replica Props Forum user firecrackthis has loved the character since he was a child. That led to him building the helmet from scratch, and it’s his first such build. He spent a month on the Rocketeer, and here are the basics of how it came together:

    i made the helmet by starting with the Pep file (had to make it twice because i didn’t realize you had to scale these things). after that i coated it in some resin, then fiber glassed it. was only able to put one full layer of bondo on it didn’t have time to do more so i spot filled and sanded like crazy. used an epoxy clay for the details, then primed it in black, and spray painted it an antique gold. for the lenses i used a pair of those over sized Elvis glasses and put a layer of window tint over them and just hot glued them inside the helmet.

    Japan allocated 4 bln yen to launch national 3D printing project #3DThursday #3DPrinting #3DScanning #3D

    Pasted Image 4 3 14 2 41 PM

    Japan allocated 4 bln yen to launch national 3D printing project, from 3Ders.org:

    …The Japanese government has allocated 4 billion yen ($38.6 million) in funding for its national 3D printing projects, including the research and development of 3D printing machines and refined 3D molding technology.

    Among which, 3.2 billion yen funding will be allocated to support research and development of 3D printers capable of producing end use products in metal for industrial use. Another 550 million yen will be used to develop super-precision 3D printing technology, including Fused Deposition Modeling, Selective Laser Sintering, as well as technology for post-processing and powder recycling. The remaining 250 million yen is for developing new 3D measurement devices and image processing software.

    In the short term, Japan plans to support the use of 3D printers in educational settings where students may receive hands-on experience in learning about 3D data and 3D printing technology. By bringing 3D printing technology to students, they hope to provide skills and experience to their students which will allow them to become comfortable working with these tools in research and design – while also engaging their imaginations.

    …Japan’s long term goal is to build the most advanced industrial 3D printer by 2020 to make a major impact on the 3D printing market. Internationally, the 3D printer market is already dominated by the United States and Germany, with 75 percent and 15 percent market share, respectively. Japan’s share is just 0.3 percent. If Japan’s nascent 3D printer industry can produce some success stories, the field could really take off…

    NEW PRODUCT – Panel Mount 1K potentiometer (Breadboard Friendly) – 1K Linear


    NEW PRODUCT – Panel Mount 1K potentiometer (Breadboard Friendly) – 1K Linear: This 1K potentiometer is a two-in-one, good in a breadboard or with a panel. Its a fairly standard linear taper 1K ohm potentiometer, with a grippy shaft. Its smooth and easy to turn, but not so loose that it will shift on its own. We like this one because the legs are 0.2″ apart with pin-points, so you can plug it into a breadboard or perfboard. Once you’re done prototyping, you can drill a hole into your project box and mount the potentiometer that way.

    Turning The Makerbot Into A Tattoo Machine


    ENSCI les Ateliers, the famous design school in Paris, had a “Public Domain Remix” and hackathon recently, with teams splitting up to remix public domain and other free-to-use IP in projects. Most of the teams came up with similar ideas, but one team went above and beyond the call of duty; they turned a 3D printer into a tattoo machine, capable of inking a real, live human test subject.

    The build began by plotting a circle with a pen onto a piece of paper. This evolved into printing a tool holder for a tattoo machine graciously provided by an amateur tattoo artist. Tests with “artificial skin” (any one care to hazard a guess at what that is?) were promising, and the team moved on to a human guinea pig.

    The biggest problem the team faced is that humans aren’t flat. They tried a few tricks to tighten the skin around the area to be tattooed – metal rings, elastics, and finally the inner tube from a scooter. In the end, the team was able to tattoo a small circle on the forearm of the test subject.

    It’s an extremely simple and small tattoo, and scaling this build up to a sleeve would be difficult. A better solution would be to create a point cloud of an arm before going for a much larger tattoo.

    Bits to Atoms Guide to Designing and 3D-Printing Tested Nametags #3DThursday #3DPrinting #3DScanning

    Pasted Image 4 3 14 2 36 PM

    Handy nametag designed tutorial. Bits to Atoms: Designing and 3D-Printing Tested Nametags @ Tested:

    The first step was to simply sketch out how the logo would break down into parts for printing. Since the Tested logo is made up of simple shapes the break down and modeling were relatively simple.

    In the TARDIS article I mentioned using a backdrop picture to build on top of and Norm supplied me with some Tested logos files, not knowing what purposes they would be used for! A dimmed down version of the logo was used in the top view and the geometry was built right on top of it. Since mechanical precision wasn’t needed, a simple cube was stretched out and modified by eye to match up with each piece.

    The ‘Tested’ text could easily be built from scratch since it’s so blocky, but there’s an even easier option if you can find the actual font, which is free at one of my favorite sources, dafont. Most modeling programs will have a text tool that will allow the letters to be extruded into 3D models which saves a ton of time.

    This can get a little messy since geometry is automatically generated, so keep an eye out for problems. In this case, the ‘D’ in ‘TESTED’ was an issue since it generated a non-manifold edge which, as we discussed last time, is when more than two faces are sharing the same edge, therefore creating impossible geometry. I fixed this by deleting the offending part, rebuilding it and printing it as a separate part from the rest of the ‘D’….

    3D/DC: Third Edition – 3D Printing Panels and Tech Demo on Capitol HIll, May 7th #3DThursday #3DPrinting


    Public Knowledge has announced their latest 3D Printing focused event on Capitol Hill for May 7th. 3D/DC: Third Edition – 3D Printing Panels and Tech Demo:

    On Wednesday, May 7, 2014, Public Knowledge will host its third annual 3D/DC event on Capitol Hill. The 3D printing community includes small startups, academic researchers, multi-million dollar companies, and everyone in between. This event will feature a wide array of participants from across the country representing the diverse 3D printing community.

    3D printing is a technology that turns digital files into physical objects. Once you design an object on your computer, a 3D printer builds it, layer by layer, out of plastic, powder, metal, or some other material. Last year’s 3D/DC event even featured a 3D printer that used sugar. And this May, 3D printing returns to Washington, DC in full force.

    This event will be a reception and open to the public. Please RSVP here.

    The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! We also offer the MakerBot Digitizer in our store. If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
