    Awesome Gipsy Danger with a Chain Sword Costume


    femme gipsy danger

    Pacific Rim has my heart for many reasons, and one is because it gave us Jaegers. Cosplayers are building replicas of the mechs, and Nona Neon Cosplay made an incredible femme version of Gipsy Danger. She crafted the armor and painted it just right and guess what? She also made the chain sword. Awesome.

    She crafted the piece from wood. You can see a couple of in progress photos below. She cut the notches with a jigsaw, used a table saw for the bevels, and a hand sander to make the blade’s tip. She applied 2mm foam for the plates. Here are a few specifics:

    The base is cut from a piece of pine wood, the middle details are 2mm foam detailed with a woodburner. Spray painted with dark gray and metallic silver spray paint and finally hand detailed with acrylic paint

    Total Cost: $7.50

    Work Time: approx 6 hours

    Trinket powered geiger counter #trinket



    Trinket powered geiger counter:

    Lately I have been messing around a bit with microprocessor powered geiger counters. One smart guy came up with the idea of generating high voltage using PWM signals from the microprocessor itself. With some additional external parts a HV supply and negative going pulse suitable for microprocessors is easy to make. H

    …The circuit works as follows: A ~1 Khz squarewave turns the MPSA44 high voltage transistor on and off, generating high voltage when the  inductors current is shut off. The voltage depends on the pulse width of the square wave which can be tweaked in software. The 1N4007 diode rectifies this voltage, and the HV cap removes most of the ripple on this voltage. The resistor limits current to the GM tube. The current pulses from the tube generate a voltage drop over the 100K resistor which turns on the BC546. When this happens the voltage through the 10K resistor is pulled to ground, generating a negative going pulse each time the GM tube detects an ionizing ray or particle.

    To drive this circuit I used my new Adafruit Trinket, a small board with a Attiny85 microprocessor. Using the tutorials on the Adafruit website it is easy to work with from the Arduino environment….

    Adafruit Trinket – Mini Microcontroller – 3.3V Logic: Trinket may be small, but do not be fooled by its size! It’s a tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power. We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. Perfect for when you don’t want to give up your expensive dev-board and you aren’t willing to take apart the project you worked so hard to design. It’s our lowest-cost arduino-IDE programmable board! The Attiny85 is a fun processor because despite being so small, it has 8K of flash, and 5 I/O pins, including analog inputs and PWM ‘analog’ outputs. We designed a USB bootloader so you can plug it into any computer and reprogram it over a USB port just like an Arduino. In fact we even made some simple modifications to the Arduino IDE so that it works like a mini-Arduino board. You can’t stack a big shield on it but for many small & simple projects the Trinket will be your go-to platform. (read more)

    Breadboard based modular system #MusicMonday



    Via Studio for STEIM.

    From May 1 through May 14th, Pete Edwards and Phillip Stearns have been working on developing an open platform for endless musical and electronic invention, exploration, and discovery from the bottom up or the top down. This system is based on minimizing the differences in the input and output “languages” used in various musical electronic formats. This means finding a way to allow free communication between logic, analog and eventually digital electronics. We are working to achieve this by finding a middle ground between these mediums where signal format and amplitude can be shared freely with minimal need for translators and adaptors. Our proof of concept models have shown that unhindered communication between binary logic and variable analog systems renders wildly adventurous possibilities and a unique musical character.

    The form factor ethos is one where our passion for invention and performance are given equal attention. The key to achieving this goal is designing a hardware system with maximal scalability of size, quality and hardware format. Thus allowing the experimenter to quickly and cheaply connect circuit boards with simple jumper wires. Meanwhile the traveling musician may prefer to adapt their system to be held in a rugged housing with large format control hardware. This is effectively achieved by adopting a standard layout for a set of core modules which can be built up to the appropriate scale using a series of shields and pluggable add ons.

    NewImage

    After a series of discussion on what such a system might look like and how to establish a standard that could be as flexible as possible, allowing for the nesting of micro and macro elements, we began prototyping modules and stackable hardware interfaces.

    Project documentation is still underway, with schematics for the prototypes still in development, however, we have, after only two weeks, produced a functional system that fulfills many of our goals including portability, quick system (re)configuration, open patchable interconnection architecture, and stable breadboard compatible form factor with the potential for stackable shields and interfaces.

    Future plans discussed for the project include the development of VCO, VCA, and VCF modules that operate on 5 volts, releasing schematics and system specifications to the public, production of low profile breadboard compatible modules in kit and pre-fabricated form with options for either through hole or smd components.

    This online test will help determine if you are tone deaf #MusicMonday


    ToneDeafTest com Find out if you are tone deaf or not

    Try it out for free here! Here’s some information from the site:

    Most people who think they are tone deaf do in fact have the pitch discrimination abilities necessary to be great musicians. It is actually a lack of musical training which is to blame for their apparent difficulty judging notes.

    This Tone Deaf Test is designed to measure your pitch sensitivity. This tests whether you have the fundamental abilities you need, which can then be developed and improved through ear training and singing practice.

    The test is divided into three stages, each of which tests a different pitch judgement skill. Your overall score is used to determine the likelihood that you are truly tone deaf. If you pass the test you can be quite confident you have the fundamental pitch abilities required to become a good musician.

    Please note that although the test has been designed by experienced music educators based on scientific research into tone deafness, it is not a clinical diagnosis. If you fail the test, this is not diagnosis of a cognitive impairment and it is possible you can still develop your ears for music.

    Using Public Data to Make Laser Cut Maps

    laser cut maps

    If you have access to a laser cutter you’re going to want to take a look at this brilliant tutorial. [Steven Smethurst] has figured out how to extract public map data and turn it into a file ready to be laser cut onto your choice of material.

    In his example he’s using Vancouver’s Open Data Catalog to build his map using the coastal and public street data. To do this he’s using a program called TileMill which you can get for free from MapBox — it’s a great piece of software for designing your own interactive maps — and the best part is, you can import data from a wide variety of sources, such as Vancouver’s Open Data!

    You can import the shape (.SHP) files from the Open Data Catalog and add them as layers into TileMill. From there you can manipulate your map, adjust the detail, and then import as a .SVG or .DXF file ready for laser cutting.

    In addition to the Instructable on how to do this, he’s also recorded an in-depth video tutorial which you can check out after the break.

    James Dyson Is Designing A Giant Vacuum-On-A-Boat To Clean Ocean Trash


    3028391 inline s mvupdated

    Fastcoexist has a story on James Dyson’s plans to develop a giant vacuum designed to clean up pollution in our water.

    “By skimming a highly concentrated flow of larger sized plastics in polluted rivers, the M.V. Recyclone would effectively mine a major source of the pollution before it reached the sea,” the British engineer explained in an email.

    “Large skim nets unfurl from the rollers at its stern and are anchored on each side of the river. Hydraulic winches wind them in and out. The nets face upstream and skim the surface of the river for floating debris. The plastic waste is shredded on board and then different grades of plastic are separated by a huge cyclone–very similar to the way our cyclonic vacuums work,” he said.

    Dyson first sketched out the idea for Time, but we asked him for a few more details. Originally, he thought the machine would be more like a “grid” fixed at certain strategic points of the river. But he eventually decided that wouldn’t have the scale or mobility of a boat. Hence the M.V. Recyclone barge.

    What’s Inside a USB Isolator?

    Coil Die

     

    In this acid powered teardown, [Lindsay] decapped a USB isolator to take a look at how the isolation worked. The decapped part is an Analog Devices ADUM4160. Analog Devices explains that the device uses their iCoupler technology, which consists of on chip transformers.

    [Lindsay] followed [Ben Krasnow]‘s video tutorial on how to decap chips, but replaced the nitric acid with concentrated sulphuric acid, which is a bit easier to obtain. The process involves heating the chip while applying an acid. Over time, the packaging material is dissolved leaving just the silicon. Sure enough, one of the three dies consisted of five coils that make up the isolation transformers. Each transformer has 15 windings, and the traces are only 4μm thick.

    After the break, you can watch a time lapse video of the chip being eaten by hot acid. For further reading, Analog Devices has a paper on how iCoupler works [PDF warning].

    Symbiotic Machine: A robot that feeds on algae #robotics



    Ivan Henriques has made this strange but cool robot that feeds on algae.

    Sealed with a transparent cylinder a motor, an endless worm and a pepper grinder aligned and connected by one single axis compose the mouth/anus, like a jellyfish. This cylinder has a liquid inlet/outlet (for water and algae spirogyra) placed at the end part of the endless worm. The endless worm has an important function to pump liquid in and out and to give small propulsion for the machine. Once the motor is activated the endless worm can turn to the right or to the left. If it turns to the right it sucks liquid in. If it turns to the left it pushes liquid out. The machine is programmed to pump algae and water in and out by the information transmitted by the sensors.

    In order to “hack” the algae spirogyra photosynthesis’ and apply it as an energy source, the algae cell’s membrane has to be broken. The pepper grinder that is connected at the end of the endless worm can grind the algae breaking the membrane cell, releasing micro particles. These micro particles in naked eyes looks like a “green juice” which is flushed inside the machine: the stomach.

    A tube that comes from the end of the mouth with grinded algae goes though the stomach inside the ellipsoid of revolution. This tube is fastened on a 2-way valve placed in the center of the spherical shape.

    NewImage

    Inside the ellipsoid of revolution there is another bowl, just one centimeter smaller aligned in the center. Placing this bowl inside, it creates two chambers: 1] the space between the outer skin and the bowl and 2] inside the smaller bowl. In chamber 1 the photocells are placed in parallel and in series. The photocell is composed by a plate covered with gold, a spacer in the middle covered with a copper mesh. This set up allows the “green juice” rest between the gold and copper. After the light is shed on the electrons of the grinded algae they flow to one of these metals, as a lemon battery. As all the photocells are connected, with the help from the electronic chip LTC 3108 Energy Harvester is possible to store these milivoltages in two AA rechargeable batteries.

    (A life cycle with functions was idealized in order to program the machine and activate independent mechanical parts of the stomach: it has to eat, move, sunbath, rest, search for food, wash itself, in loop)

    The 2-way valve mentioned above is connected as: valve 1 hooked up with chamber 1 and valve 2 with chamber 2. When the stomach works is sent information to the machine that the valve 1 has to be opened. The algae flow to this chamber and the machine uses a light sensor to go towards where there is more luminescence to make photosynthesis. It rests for ten minutes. After the 10 min sunbath the machine has to clean its stomach – and the photocells – to be able to eat again. Water is sucked in again with the mouth, and via the same valve from the algae, it pumps more water inside chamber 1 in order to have an overflow of this liquid in chamber 2. The liquid, which is now in chamber 2 is flushed out by the motor turning the endless worm and having the valve 2 opened.

    Fixed on the edge of the structure opposite the mouth, an underwater pump connected by a vertical axis with a servo powers the movement of the structure giving possibilities to steer 0; 45 and minus 45 degrees.

    AMLGM Envisions Urban Alloy Tower Over Transportation Hub in NYC


    Img 12 1397344907 8d484e12f4e4be523e567a92356831a0

    AMLGM has developed a city redesign plan called “Urban Alloy,” which focuses on re-imagining the space around existing transportation hubs in the outer boroughs of NYC. Via designboom.

    From AMLGM:

    Living Concept:

    The combination of escalating land prices and the acceleration of city migration have made urban renewal based modes of densification unfit for the contemporary city. Urban Alloy is the symbiotic re-purposing of the air rights above transportation corridors in New York. Urbanist’s have long touted the benefits of greater housing density near public transportation hubs – Urban Alloy proposes the advancement of this idea by locating the system directly on the intersections between surface and elevated train lines. We have chosen the intersection of the LIRR and the 7 train as a test case. The paradigm of one size fits all is obsolete. Urban citizens want diverse living situations where they can work, play, eat and rest within a pedestrian zone. As technology creates the market desire and a conditioning for personalization, society is more willing to pay a premium for spaces that are tailored to their particular needs. See Program Diagram describing the wide range of living options.

    Skin Concept:

    The wide range of programmatic options inspired a blend of floor plate geometries that transition from cylindrical to triangular from the base to the top of each tower. This blend, along with constraints instilled from the site, generates a complex geometry that requires a new facade optimization paradigm. A composite or alloy of multiple flexible systems is required to optimize a skin in which every point has a unique environmental exposure. The system is deployed on a grid that follows the geometric directionality of the surface. At each intersection of the grid, the normal of the surface is analyzed against its optimal solar shading and daylight transmitting requirements. An authored algorithm then generates vertical and horizontal fin profiles that blend with the profiles at adjacent nodes. The result is an optimized system of decorative metal fins that are unique to each specific solar orientation. Based upon the tenants of current solar facade design, the algorithm utilizes deep horizontal fins along southern exposure, and deeper vertical fins alongs east and west facing surfaces. This system generates specific fin depth and orientation for every point on the surface.
