HOW TO GET WHAT YOU WANT Relief Embrodiery Relief embroidery on leather is traditionally used in Austria to create decorative patterns on the surface of the leather used in Lederhosen. The embroidery thread does not pass through the material, instead it is stitched back and forth, pulling together the leather and creating a “bump” (germ. “wulst”). This bump also serves a purpose of […] Ikat Woven Conductive Thread Ikat is a technique of partially dying yarns before weaving them to create a patterned fabric. Batik Etching Conductive Fabrics Using Batik was as a resist, applying it to copper fabric and etching in a salt and vinegar bath. Dyeing Conductive Yarn Conductive yarns are often in gray color which makes your project looks grayish. Weaving Conductive Fabric Commercially available conductive fabrics are mostly evenly coated basic woven and knit structures. Fabric Pleating Chris Palmer demonstrated how to pleat fabric using a technique of pre-stitching it together with thread. Machine Felting needle felting (wet)

GROVE System Grove is a modular, ready-to-use tool set. Much like Lego, it takes a building block approach to assembling electronics. Compared with the traditional, complicated learning method of using a breadboard and various electronic components to assemble a project, Grove simplifies and condenses the learning process significantly. The Grove system consists of a base shield and various modules with standardized connectors. The Base shield allows for easy connection of any microprocessor input or output from the Grove modules, and every Grove module addresses a single function, such as a simple button or a more complex heart rate sensor. Grove Modules A wide range of Grove modules are available for use within the Grove System.

MIDI | code, circuits, & construction MIDI, or Musical Instrument Digital Interface, is a specification for a communications protocol between digital synthesizers and other digital music devices. It was developed to be as simple and general as possible, to give synthesizer manufacturers as much flexibility as possible, yet still have their instruments talk to each other without communication problems. MIDI does not define the nature or timbre of a synthesized sound. It merely describes the action of playing the sounds. In a sense, MIDI is a markup language for synthesizers. MIDI is to digital synthesizers what HTML is to the web. As a communications and control language for musical instruments, it’s imperative that MIDI be fast. Although MIDI is at its core a simple protocol to grasp, there are many facets to it. MIDI is a serial communications protocol, operating at 31,250 bits per second. Note: the hex Inverter may not be necessary if your serial device (Stamp, BX-24, etc) has already done the inversion. Schematic:

A Step by Step Guide to Electronic Product Design and Development Home Industrologic, Inc. (636) 723-4000 Products Page A Step by Step Guide to Electronic Product Design and Development A well executed design and development cycle for an electronic product requires travel through many stages before arriving at a successful conclusion. 1. The stage where an idea for a new product, a variation on an existing product, or the identification of a need for an undefined product causes research to be done to define a product, a market, and an approach for manufacturing this product. 2. The stage at which the product concept is utilized to fuel research that includes identifying the technology, methods, and vendors involved in producing the product. 3. The stage where a schematic diagram is created (usually via computer drafting software) and a preliminary parts list is created for costing and prototyping the product. 4. This is the stage where the device under design gets a suitable enclosure designed or selected. The major steps in this process are: 5. 6. 7. 8.

The TwEECer -- EEC user programmable module The TwEECer We offer two models of our product, the TwEECer Base and TwEECer RT, either of which can be used with any EEC we support. There is no vehicle year or model specific variations to our TwEECer products. Everything you need to tune your setup is included in the purchase price, TwEECer, Switch, Cables, Software (download from our website). TwEECer Features: Unlimited tuning capability Up to Four custom tune positions for the RT and Two tune positions for the Base Update and switch between calibrations while the motor is running ** Fifth position disables TwEECer and reverts to stock calibration Position one can easily be set as a Kill or Valet switch Easy to use software for tuning and logging ** Only for TwEECer RT during partial updates, full writes take up to 10 seconds What is the difference between the TwEECer and TwEECer RT? Unlike most other "chip" makers, you do not have to shut off the vehicle and remove the TwEECer to update tuning parameters.

Designer's guide to getting started with electronic sketching | R I A Z Being able to sketch and rapidly iterate with electronics is a very powerful skill in creating tangible experiences. It allows designers to test our behavioral assumptions, both digital and physical together, with real people. Unfortunately even getting started can be daunting. Here is the collection of the best tools and resources I’ve found so far. Platforms Arduino ($30) : Think of an arduino as a really small and simple computer made by a group of crazy Italians geniuses. There are all kinds of arduino boards available now. Right now that’s the Arduino Duemilanove (which is Italian for 2009). Adafruit Starter Kit Official Arduino Website A little Arduino History Bug Labs BUGS ($579): High end modular products with open source software. Little Bits (Not Available Yet) : This is an open source hardware library of discrete electronic components. Chumby ($200): Another open source software but closed hardware device. *EDIT* Here’s a list of other toolkits available Electronics Toolbox Cool!

Build the LED ARRAY ILLUMINATOR - Page 1 of 12 A long range infrared illuminator can be made using many LEDs There are times when the small infrared LED ring built into a security camera will not cover the range or field of view you require, so you will need to find another invisible light source. Some large infrared illuminators use powerful incandescent light sources that are passed through an infrared pass filter, causing only the infrared component of the light to come through the filter. These types of infrared illuminators create intense heat due to the fact that the white light source must be fully enclosed and burn the unwanted light energy off as radiated heat. Because of this intense heat, incandescent filtered illuminators cannot be used indoors and may not be suitable for many outdoor installations. The good news is that LEDs can be used to create a very powerful infrared illumination system if you use enough of them. Figure 1 - LEDs purchased in large quantities can often be found at bargain prices You are Viewing...

Serial and Parallel Battery Configurations and Information BU-302: Configuraciones de Baterías en Serie y Paralelo (Español) Learn how to arrange batteries to increase voltage or gain higher capacity. Batteries achieve the desired operating voltage by connecting several cells in series; each cell adds its voltage potential to derive at the total terminal voltage. Parallel connection attains higher capacity by adding up the total ampere-hour (Ah). Some packs may consist of a combination of series and parallel connections. Most battery chemistries lend themselves to series and parallel connection. A weak cell may not fail immediately but will get exhausted more quickly than the strong ones when on a load. Single Cell Applications The single-cell configuration is the simplest battery pack; the cell does not need matching and the protection circuit on a small Li-ion cell can be kept simple. The nominal cell voltage for a nickel-based battery is 1.2V, alkaline is 1.5V; silver-oxide is 1.6V and lead acid is 2.0V. Series Connection Parallel Connection
