    Grad students build internet terror phone to scrape data on DoS attacks using Raspberry Pi #piday #raspberrypi @Raspberry_Pi

    NewImage

    This post from The Awl reads like a scary story straight out of some dystopian Sci-Fi future:

    Walk down Broadway, past Canal, past banks and furniture stores, Mr. Fashion and sneaker shops and condos, old then new, brick then steel, until the buildings grow taller and begin to take up entire blocks. Turn right at the unopened Pret, across from the McDonald’s, down Thomas Street, a one-way single-lane. Look up. You can’t miss it: A monolith, brutalist, granite armored, its skeleton colossal slats of moulded concrete. It is said to feature the largest blank facade in the world. The building’s six turrets contain air ducts, a whole mess of ventilation for whatever is inside. Whatever is inside—that’s the question…

    …Ponder the monolith and its innards long enough, however, and you might find inspiration. This is how a trio of grad students at NYU’s ITP (Interactive Telecommunications Program) came to build a strange new kind of emergency phonebooth.

    “We fell in love with the building,” said Omer Shapira, a filmmaker and journalist. “It’s just so insanely big, and dark, and what it contains no one knows. There are no blueprints online. Maybe there are NSA servers in there.” Shapira said that they first did their pondering before anyone knew who Edward Snowden was, and before cybercrime was something normal people might talk about. He and his partners, Max Ma and Ryan Bartley, wanted to find a way to link that building, full of phone lines, to its surroundings, full of Internet. “How about if we make this phone that shows the emergencies on the Internet,” Bartley said. “It would be like there’s this enormous building screaming for help.”

    First they needed to find a way to listen in on cyberattacks. This wasn’t difficult. Shapira said that the internet is a lot like a big echo chamber—efficient routing means redundant connections. Denial-of-service (DoS) attacks reverberate between the connections. They needed a way to tap into a connection and listen for echoes. This wasn’t easy.

    “Well, no one, big companies I mean, wanted to partner with us, to let us see how they were being attacked. I guess we shouldn’t have been surprised,” Shapira said. So they found databases of DoS attacks. The only problem with the databases is they weren’t in real time. Nonetheless, the range and frequency was astonishing. “The ones you hear about, from Anonymous usually, those are the most vanilla attacks, like on Scientology. You don’t hear about criminal organizations or governments, controlling millions of computers through a botnet to gain access to a server, or kill it,” Shapira said.

    When he first looked at the attack logs, Bartley said: “Oh my God, this was way, way bigger than we ever thought.”

    They buffered the logs by a few days, mostly so the three of them, or ITP, or NYU, wouldn’t become a target for the attackers. Then they programmed a cheap, credit-card-sized computer called a Raspberry Pi to scrape this data and spit it out. They turned the text to speech, choosing a crackly computer voice. “The feeling we want to give,” Bartley said, “is like, whenever you see a zombie movie, and the radio is replaying a message, a distress signal, that’s it.”

    This PiFace menu tutorial keeps it simple @Raspberry_Pi #piday #raspberrypi

    Pi face menu

    Using his new PiFace, this maker wrote a python script for a 5 option menu for the Raspberry Pi that you can leave running (with an adjustable backlight!), from uktechreviews.

    My prototype Python script generates 5 menu options which are accessed via the push buttons. Once pressed they either launch another script or run part of the menu script.

    I intend to leave this running so I have included two buttons to switch off the back light and turn it back on again.

    The clock option displays the current time for three seconds.

    The code is still in development and is rather ‘clunky’ (if you can use such a term!) – but it does work!

    Please feel free to use any aspect of the code and modify and improve!!!

    import pifacecad
    import time

    def update_pin_text(event):
    event.chip.lcd.write(str(event.pin_num))
    choice = event.pin_num

    Teeny-Tiny Tap-Dancers Can Teach You Tricks about Digital Signal Processing #piday #raspberrypi @Raspberry_Pi

    Teeny-Tiny Tap-Dancers Can Teach You Tricks about Digital Signal Processing. From RaspberryPi.org:

    …Here, FFTs are performed on music samples on the Raspberry Pi fast enough to detect a beat, and the Pi relays that information to some teeny-tiny tap-dancers, who produce an automated routine that’s synced to the music.

    These little tap-dancing guys are from a post-Christmas sales bin. They’re called Happy Tappers, and are made by Hallmark, who, for reasons known only to them, include a port which enables them to interface with their tippy-tapping brothers and sisters – which makes for exciting DIY project possibilities once you add something that’s able to feed them an input. I’ve never seen them on sale in the UK, but if you’re dead set on making your own tap-dancing Pi project, they seem to be available online at eBay, Amazon US, and at some Christmas shops….

    Use your pi for automated home brewing @Raspberry_Pi #piday #raspberrypi

    NewImage

    Here’s another great home brewing project using the Raspberry Pi, this time from The Raspberry Pi Hobbyist.

    I have been a “home brewer” in the electronic hobbyist sense for decades, but I am also a “home brewer” of beer. I mentioned this in my post on Reading Temperature With Thermistors.

    I now use digital temperature sensors (typically the DS18B20) read over an I2C bus. Adafruit has a good tutorial on how this is done located here.

    It is fairly common to control a refrigerator and heater to keep a constant (or slowly changing) temperature during the fermenting process, especially with lagers. I have done this using the Raspberry Pi, thermistors, and an A/D convertor. Now, I decided to get a lot more ambitious.

    I won’t go into all the details of the brewing process since there are many resources on the web to provide that. For a quick look at this process, see the article on my photo blog. I wanted to be able to control at least the following items for one of the simpler methods of brewing (called partial mash.)

    • Valve to a tank of propane
    • Grill ignitor to light the burner
    • Sensor to detect if the burner actually did light
    • Temperature sensor for the wort (the brew of water, malt extract, and hops)
    • Pump for circulating water through the wort chiller

    What I needed to do this:

    • A relay to output 12V to control the propane valve
    • Another relay to output much higher amperage of 12V to run the pump
    • A relay connected in place of the button on the grill ignitor
    • A connection for one or more DS18B20 temperature sensors

    Read more and see the full tutorial here.

    High Temp Waterproof DS18B20 Digital temperature sensor + extras: This is a pre-wired and waterproofed version of the DS18B20 sensor made with a PTFE wire cable. Handy for when you need to measure something far away, or in wet conditions. This sensor is a little more expensive than the other waterproof version we have with a PVC cable because this one can be used up to 125°C – the limit of the sensor itself. Read more.

    Food-Grade Heat Shrink – 3/8″ diameter 12″ long: We decided to stock this food-safe heat shrink specifically for people who were building beer-brewing or sous-vide projects using our waterproof DS18B20+ digital temperature sensors. This heat shrink is FDA Compliant for contact with food. The end of the sensor is stainless steel, but the jacketing is PVC, not good for dunking into your food or drink! But this heat shrink makes it easy – simply slip it on, allowing about 1 cm of the stainless steel sensor cap to be exposed, then heat it up to seal it on. The heat shrink will make a seal over the cap, so that no PVC touches your food project. Read more.

    Full-Size Power Loader Costume Is Ready For Alien Battle

    full size power loader costume

    When you’re already making a life-size statue of the Alien Queen, you may as well build a Power Loader costume to go with it. That’s Instructable user alexthemoviegeek’s attitude, and I applaud his enthusiasm. He wanted the Power Loader to be made as cheaply as possible and also wanted it to be functional. He spent about $225 on materials, and it was well worth it. Though there are many steps to the build, here’s how he made the stilts:

    Two-foot tall stilts need to be very specific. I learned that first-hand. I went to my dad’s garage where he had plenty of spare wood. I made my own design out of whatever pieces I could find. I ended up having to use an air-powered nail gun to secure the pieces of wood together. I could then build up the foam board pieces around the stilts.

    The cage was also a challenge. I’d seen other Power Loader costumes that used connected pieces of PVC pipe, but the problem with that was you could tell it was just pieces of PVC pipe, instead of a single piece of welded metal. I decided to used 1″ PVC pipes and 3/4″ connectors, both with an outer diameter of 1.25″, so that they’d have a singular diameter and look like a solid piece. I had to add some small wooden dowel pieces and hot glue to help strengthen the connections.

    Yes, it’s awesome. Just look:

    Design for 3D Printing: Prepping mechanical parts for 3D printing for Shapeways #3DThursday #3DPrinting

    Pasted Image 3 27 14 1 41 PM

    Here’s an interesting resource for how to prep files for printing mechanical parts using Shapeway’s printing service. I’m highlighting the Clearance as I found the discussion pertinent to many forms of printing, with a special consideration for SLS.

    Prepping mechanical parts for 3D printing for Shapeways:

    Designing mechanical parts for 3D printing
    What you need to know.

    Through these pictures and explanations we hope to give you a better understanding on how to design mechanical parts for 3D printing.

    • maintain a wall thickness of at least 1mm,
    • accuracy is 0.1mm,
    • always keep a clearance of 0.6mm
    • and parts may have a deviation of 0.2mm.

    When designing something mechanical that has to be 3D printed or when adding a mechanical feature to your model there are several main considerations.

    Clearance

    Clearance, the distance between a door and the door frame when the door is shut. If you make a peg with a diameter of 3mm and a hole with a diameter of 3mm, the peg will not fit into the hole. There has to be some kind of clearance at play for it to work.

    The amount of clearance would depend on the functionality of the part. The higher the clearance, the more likely it is to fit. When developing complex moving mechanical parts though, the more clearance the more inefficient the part. A good balance between clearance and efficiency is crucial for your design decisions. If you have a gear, gearbox or spring I would try to go for minimum clearance. When designing any other assembly I would go for more clearance. The minimum clearance is 0.6mm at all times. Do not go below this number or your parts will fuse.

    The reason why clearance is especially important when designing things for White, Strong & Flexible(Selective Laser Sintered parts) is because the laser melts the SLS powder and then fuses it. This coupled with the shrinkage means that if you do not get clearance right your part will fuse. So not only will it not fit exactly right it will all get stuck together and will not work at all.

    Bringing 3-D Pow(d)er to the People: Profile of 3D designer evangelist Duann Scott #3DThursday #3DPrinting #shapeways

    DuannScott

    Check out this NYTimes profile of Shapeway’s designer evangelist Duann Scott, and the efforts that he has undertaken to connect Shapeways with designers and vice versa to continue to evangelize the role he envisions for 3D printing in design in the future:

    The first thing Duann Scott does when he arrives at the Shapeways factory in Long Island City, Queens, is check the bins. They are yellow and stacked in an all-white room that resembles the interior of a spaceship, and they contain the latest prints to come out of the machines, which can really stack up.

    Shapeways, a 3-D printing service and online marketplace, has been described as the Amazon of 3-D printing for its on-demand model, if not its outsize volume: The machines spit out about 120,000 objects a month, a tidal flow of design that runs from the mundane to the astonishing.

    On a recent day, a quick search through the bins revealed a pair of pliable black-frame eyeglasses, a scale model of a biplane, an intricately detailed brass ring, enough plastic train cars to form a miniature railroad and a figurine of two tiny purple women on tiny purple trapezes. To what use any of these things will be put, Mr. Scott usually has not a clue. But that doesn’t diminish the Christmas-morning grin he gets while he is fishing through them….

    This is How 3D Printed Bagpipes Sound – Pure dead brilliant! #3DxMusic #3DThursday #3DPrinting

    While there are scores for 3D printed recorders and whistles on Thingiverse and elsewhere online, and despite delicious rumors of gorgeous 3D printed organ pipes that have not yet been posted, there are only a handful of more complex wind instruments produced via 3D printing. Well, here’s a project suggested to us by Matt Stultz on 3DPPVD.org that is remarkable not just for where the maker hopes to take it — extending the range of the instrument — but also for successful it is at nailing the being-a-bagpipe side of things. From Matt Stultz:

    Often we get too caught up with the technology behind 3D printing and don’t spend enough time thinking about the wide range of things we can do with our printers. Sometime we need to stop and smell the roses and listen to a merry tune. Now with the Dreaming Pipes project… your printer can create you a set of bagpipes (or a few other traditional instruments) so you can play your own tune. I’m really excited to see a project that is not only looking to use 3D printing to take a classic instrument to new levels but also make it affordable and easy for anyone to build….

    And from Donald Lindsay’s 3D Printed Bagpipes site:

    Ever since taking up the Scottish Smallpipes, like many pipers I’ve been curious about the idea of extending the range of the instrument. It seems like a natural progression. As pipers, when we take to the Smallpipes, it’s often to play with other musicians, and different instruments. I’ve been fortunate enough to have played the Smallpipes in a wide variety of settings, for a wide range of musicians and producers, and have often been in situations where I’ve wished I could just play something that’s out of the range of my instrument.

    …The use of technology is well established in the bagpipe making community, with CNC-milled instruments already widely played, so it wasn’t a great leap to start to consider the possibilities of 3D printing, as a medium to prototype ideas that would have been difficult for me to model in other ways. So in early 2013, taking with me the note book I’d filled with the results of my various experiments, I made my way to The Lighthouse in Glasgow. Built by Charles Rennie MacKintosh as his first public commission, The Lighthouse was at the time the home of MakLab, the first maker’s laboratory I was aware of in Glasgow. At time of writing, MakLab is in the process of moving to larger premises in the Charing Cross area of Glasgow.

    At MakLab, I learned to use 3D printers, beginning with the original Ultimaker. Printing chanters vertically, using a ‘built-in’ sole as the support, and no support material (it destroys the instrument’s tone), I was able to print several chanters to different designs, before work and life commitments meant that I no longer had time to spare for a while. Moving on to Shapeways, as being quicker for me (if a little more expensive), I continued prototyping. By February this year I was ready to print a full set of Smallpipes. To keep costs down, and for reasons related to the large chalice-style tops I’m currently using, the first print is essentially a set of “Parlour Pipes” having separate drone stocks. It maintains the Bass-Baritone-Tenor arrangement common to Smallpipes however, and internally experiments with a couple of the more basic ideas I have for drone design.

    The pipes, printed by 3DprintUk in London, arrived yesterday (14th March), and I was lucky to be able to pay a visit to Ronnie McShannon at Pipe Dreams in Glasgow, for help with the reeds, and James Begg of Piping Perfection in Glasgow, who kindly supplied a good quality bag for the instrument….

    Pillarhouse JadeMKII Selective soldering – APEX EXPO #adafruitAPEX @IPCShow #IPCshow #apexexpo

    Jademkii
    We are at the APEX Expo looking for a selective soldering machine, we stopped by the Pullarhouse booth to check out the Jade Series – specifically the Pillarhouse JadeMKII Selective soldering machine.

    Adafruit 2803

    Selective Soldering is the process by which conventional leaded components are soldered onto a printed circuit board. This process is usually conducted after the surface mount reflow soldering operation. With the increasing popularity of Lead Free solder and its associated high cost to fill a large conventional wave solder machine bath, Selective Soldering offers a significantly lower cost approach with inherently smaller bath design and the added advantage of quick change capabilities i.e. from lead free to eutectic and vice versa.

    It is often necessary to process leaded components which are in a very close proximity to surface mounted parts. Selective Soldering offers the ability to accurately control a nozzle flow under nitrogen inertion so that parts can be soldered without any damage to the nearest surface mount devices.
    
In some cases we can solder points as close as 1mm to the nearest surface mount component, thus offering a highly flexible and cost effective solution.

    For users who demand a small footprint but large board capability the new JadeMKII is the perfect fit. by incorporating a board support system that can hold a PCB of up to 457mm x 508mm (18″x20″) along with its simple hand load operation provides the user with great flexibility for quick changes in small batch processing which keeps the cost down and the production up.

    • Integral PC and Machine Mounted TFT Monitor
    • Inerted Nitrogen System
    • Auto Solder Top-up (Wire Feed) & Solder Level Detect
    • Drop Jet Fluxer
    • Two AP-1 Solder Nozzle Tips
    • Internal Fume Extraction
    • Colour Programming Camera
    • Universally Adjustable Tooling Carrier
    • 457mm x 508mm Maximum PCB Handling Size
    • PillarCOMM Windows Software
    • Lead Free Capability
