Fiber Optic Dress The design of the dress followed the fiber optics that it needed to support. As there is one central light source, I designed the back to include a pouch for the handle, and the straps of the dress to bring the fiber optics from the center back to the front, and back around the body to an even distribution at the hips. A big design challenge was how to give the filaments enough lift at the skirt, as I wanted the skirt to push them out at as near to a 90 degree angle as possible. I was considering things like a fully boned structure or 3D printing small pieces for each group of filaments to angle them out at a perfect right angle. Be warned that this Instructable includes a major fail at one point, so read the whole thing first if you intend to make this. I chose to make this dress from scratch to dust off my fashion skills, but you could definitely make something very similar by buying a V-neck dress with a circle skirt and skipping to step 13.
Android Adventures Go to part 2… I finally got a smartphone: Samsung Captivate. Why? Mainly since the bar for making apps on them seems pretty low, which is something I’ve wanted to try for some time. Plus after seeing these two posts… And their reference to Processing For Android… …and considering my love for Processing… …it just all seemed to make sense. The first thing I wanted to do though had nothing to do with Processing: I wanted to get the ‘Scripting Layer For Android‘ (SL4A) installed on it so I could run Python (which I love more than Processing), in a shell, on my phone. Disclaimer: I’m a total smartphone\Android noob, and this is the first time I’ve ever written words like ‘sideload’ or ‘root’. A. AT&T in its infinite wisdom has disallowed ‘sideloading’ of apps onto the phone: You can’t copy something onto the internal SD card and ‘install’. After a lot of websearching, I came across this form post, which describes how to install the “Unleash the Beast” root tool. Excellent, root complete! B. C.
Home Alert: Arduino + Cloud Messaging On A Large Display In the age of mobile phones, you would expect that people would be responsive to your call 24/7. Or… not. Once my wife gets home, the phone stays buried in her hand bag, or its battery is flat. We don’t have a land line. I have this problem often enough to warrant a solution. Home Alert is made of these parts: A Freetronics Dot Matrix Display, which is an array of 16x32 LEDs. Home Alert is controlled via a web page that is hosted on Heroku, a cloud-based application host. Have a look at the home page (show in the first attached image in this step), where the form awaits a new message from the user. The first field accepts a numerical hardware code. The message you want to display goes to the second field. If you want to make some noise, check the Yes! In this article, I’ll show you how to build your own Home Alert system, both Arduino hardware and software, as well as the Sinatra mini web application. Let’s get started!
Setting up Processing for Android development environment Calligra/Building - KDE Community Wiki These instructions are for Unix and similar operating systems. For Windows, see the building Calligra on Windows page. For OSX, see the building Calligra on OSX page. Recommended Setup Here is recommendation of a directory structure: $HOME/kde4/src/ source code $HOME/kde4/build/calligra directory that Calligra will be built in $HOME/kde4/inst directory that Calligra will be installed in The build directory is needed because you cannot (or should not) build Calligra inside the source directory; the source and build directory have to be separated. Create these directories with: mkdir -p ~/kde4/src; mkdir -p ~/kde4/build; mkdir -p ~/kde4/inst Advantages of this setup: It is possible to have different builds (e.g. with different options out of the same source code) David Faure's scripts can be used to make development easier. Also, check the Techbase instructions on setting up a build environment. Getting the Source Code There are two most useful options: If unsure pick the stable version. Then execute $ .

NodeBots - The Rise of JS Robotics Electric Coffee Maker This instructable is for making a sustainable electric coffee maker. Nearly all components are from readymade diy parts & materials, so if any part ever breaks, you can repair or replace it. The parts from the casing were printed using Filabot filament, which is made out of recycled plastic. Other parts are made by casting local waste aluminum (such as cans, aluminum foil and chips from cnc milling aluminum). There is no glue used so you can always disassemble and reuse/recycle every part. I tried using as much locally produced parts as possible and using as many parts as possible which are not related to a specific model or product. I made everything by learning from online tutorials, by using as much scrap material as possible and by utilizing the local fablab: Fablab Genk. NOTE: This is a prototype, so some components or parts might have to be optimized. Please keep all safety aspects in consideration.
Cómo hacer un backup de tus PPA en Ubuntu Aptik permite crear una copia de respaldo (backup) de los PPAs y paquetes instalados, así como también de los temas y los íconos, simplificando la reinstalación de los mismos en una copia “fresca” de Ubuntu y derivados. No hay duda de que esta herramienta es ideal para quienes sufren de “versionitis” o para quienes deben instalar Ubuntu en varias máquinas. La aplicación, realizada por el mismo desarrollador de Conky Manager, no es más que una bonita interfaz a las poderosas herramientas de línea de comandos que hacen el “trabajo sucio”, pero esa es precisamente su mayor ventaja: convertir una tarea tediosa en una increíblemente sencilla e intuitiva. Instalación Abrir un terminal e ingresar los siguientes comandos: sudo apt-add-repository -y ppa:teejee2008/ppa sudo apt-get update sudo apt-get install aptik Cómo crear una copia de respaldo Al abrir Aptik, se nos presentan 4 opciones para realizar copias de respaldo: Cómo recuperar la copia creada
Camera board available for sale! The camera boards are now available for order! You can buy one from RS Components or from Premier Farnell/Element14. We’ve been very grateful for your patience as we’ve tweaked and refined things; it’d have been good to get the camera board out to you last month, but we wanted your experience to be as good as possible, and we’ve been working on the software right up until last night. Tehzeeb Gunza at OmniVision coordinated things from their end, and helped us with sensor selection. Click to enlarge. For such a small device, this has been an enormous project, and a year-long effort for everybody involved. How to set up the camera hardware Please note that the camera can be damaged by static electricity. The flex cable inserts into the connector situated between the Ethernet and HDMI ports, with the silver connectors facing the HDMI port. The camera may come with a small piece of translucent blue plastic film covering the lens. How to enable camera support in Raspbian sudo apt-get update
