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)
Curious Inventor Blog - Eagle vs KiCad Computer Power Supply to Bench Power Supply Adapter Step #13: Add Labels For Each Pair of Terminals PrevNext To help keep track of the different voltage outlets, I labeled each pair of terminals. You can print out a simple label and attach it to the top face of the housing between the positive and negative terminals.
Circuit Simulator Applet This is an electronic circuit simulator. When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage. To turn a switch on or off, just click on it. The "Circuits" menu contains a lot of sample circuits for you to try. Full Screen version. Directions. Standalone (offline) versions.

Quick start guide What you will need Required SD CardWe recommend an 8GB class 4 SD card – ideally preinstalled with NOOBS. You can buy a card with NOOBS pre-installed, or you can download it for free from our downloads page.Display and connectivity cablesAny HDMI/DVI monitor or TV should work as a display for the Pi . For best results, use one with HDMI input, but other connections are available for older devices. Use a standard Ethernet cable for internet access.Keyboard and mouseAny standard USB keyboard and mouse will work with your Raspberry Pi.Power supplyUse a 5V micro USB power supply to power your Raspberry Pi. Not essential but helpful to have Internet connectionTo update or download software, we recommend that you connect your Raspberry Pi to the internet either via and ethernet cable or a wifi adapter.HeadphonesHeadphones or earphones with a 3.5mm jack will work with your Raspberry Pi.

Wings 3d How to Convert a Computer ATX Power Supply to a Lab Power Supply Edit Article Edited by Abizarl, Krystle C., Jack Herrick, Vertent and 42 others Computer power supplies cost around US$30, but lab power supplies can run you $100 or more! By converting the cheap (free) ATX power supplies that can be found in any discarded computer, you can get a phenomenal lab power supply with huge current outputs, short circuit protection, and reasonably tight voltage regulation on the 5V line. On most power supply units (PSUs), the other lines are unregulated. Ad Steps 1Look online or at your local computer store for an ATX computer power supply, or dismantle an old computer and remove the power supply from the case.Ad 2Unplug the power cable from the power supply and turn off the switch on the back (if there is one). 13 Plug the power cable into the back of the power supply and into an AC socket. Tips You can use your power supply 12V output as a car battery charger! Warnings If you suspect the power supply is damaged, do not use it!
NEETS - HvWiki From HvWiki NEETS is an acronym for United States Navy Electricity & Electronics Training Series. The NEETS series consists of 24 modules, each covering a specific topic in the field of electricity and electronics. Because it is a work of the US government and therefore in the Public Domain, contents of the NEETS documents may be copied verbatim without restriction. This may be useful for adding content to HVWiki without concern of copyright infringement, for reference material, and general electronics training. Purpose The Navy Electricity and Electronics Training Series (NEETS) was developed for use by personnel in many electrical and electronic related Navy careers. The series is designed to give small amounts of information that can be easily digested before advancing further into the more complex material. Contents Module 7 - Introduction to Solid-State Devices and Power Supplies is similar to module 6, but it is in reference to solid-state devices. Module 8 - Introduction to Amplifiers
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.
Home | YafaRay Raspberry Pi as an Ad Blocking Access Point This tutorial will show you how to use your Raspberry Pi as a WiFi access point that blocks ads by default for any devices using it. This is really neat in that it would work for your Android or iOS device, your Xbox 360, TiVo, laptop, and more without needing to customize any of those devices other than to use your Raspberry Pi as the access point for WiFi. Using an ad-blocker can be useful for conserving bandwidth, helping out low-power devices, or for keeping your sanity while browsing the web! I do suggest whitelisting your favorite ad-supported sites so that you can continue to support them (this tutorial shows how to do this as well). It's not easy keeping up with those wily ad serving companies so we'll also setup a way to keep your ad blocking lists up to date as part of this tutorial. I used many pages as inspiration in order to set this up, including, but not limited to:

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!
