SparkFun is an online retail store that sells the bits and pieces to make your electronics projects possible. Whether it’s a robot that can cook your breakfast or a GPS cat tracking device, our products and resources are designed to make the world of electronics more accessible.

In addition to products, SparkFun also offers classes and online tutorials to help educate individuals in the wonderful world of embedded electronics.

What Is The RedBoard?

Arduino is one of the most popular physical computing platforms available today. It’s an amazing tool for both experienced and budding electronics enthusiasts. It’s part hardware, part software, and part community; all of which come together to create a well-supported, solidly-designed electronics platform.

The best part: the entire Arduino project – both hardware and software – is open-source. The schematics, hardware design files, and source code are all freely available for viewing and modification. Released under a Creative Commons Share Alike license, anyone is free to riff on the hardware design and produce their own version. That’s what we’ve done with the RedBoard. It still looks and acts just like an Arduino Uno, but is slightly modified to make the board better-suited to our purposes.

Description: If you’re new to electronics and programming, the RedBoard Starter Kit is a great way for beginners to get their foot in the door. This little guy is essentially a mini SparkFun Inventor’s Kit (minus the manual which you can find below) and can be taken straight out of the box to help you make a slew of basic circuits, including:

  • Blinking LEDs
  • Making (bad) music
  • Responding to buttons
  • Twisting a volume knob
  • Detecting ambient light
  • Reading temperature
  • Mixing LED colors
  • And more!

This version comes with our newest SparkFun RedBoard! Also included is a multitude of parts and sensors so you can start messing around with projects.

Here’s a few simple tutorials to get you started:

And here’s some more advanced tutorials, if you’re ready to take on more of the Arduino world!

Resources

For more information on the SparkFun Redboard, check out our product page. We’ve also got:

  • Schematics – A PDF of the schematic.
  • Eagle Files – The PCB design files. This design is completely open-source!
  • FTDI Drivers – Though they’re included with Arduino installs, this is where you’ll find the most up-to-date FTDI VCP drivers.
  • Product Video – A video introduction of the RedBoard.

Description: The Digital Sandbox (DS) is a learning platform that engages both the software and hardware worlds. It’s powered by a microcontroller that can interact with real-world inputs – like light or temperature sensors – while at the same time controlling LEDs, motors, and other outputs. The Digital Sandbox is equipped with everything, on board, that you will need to complete 13 experiments including controlling an LED, measuring how loud things are, detecting what the temperature is, and more. Think of this as a SparkFun Inventor’s Kit all in one board!

By interfacing the Sandbox to your computer via a USB cable, the Sandbox can be programmed using the popular Arduino programming environment. To further simplify the learning experience, we’ve designed the Sandbox and its guide around using a simple, “blocky”, programming add-on to Arduino called, Ardublock. Using ArduBlock – a simple, graphical version of the popular Arduino programming language – you will be able to program all of the experiments with a simple graphical interface instead of writing code.

The full-color Digital Sandbox Guide (included) contains step by step instructions of how to connect each circuit with the included parts. Full example code is provided and explained and even includes troubleshooting tips if something goes wrong. The kit does not require any soldering and is recommended for beginners ages 8 and up.

Sigil supports both WYSIWYG and code-based editing of EPUB files, as well as the import of HTML and plain text files.[3][4]

Features

Sigil’s features include:[5]

  • Full UTF-16 and EPUB 2 specification support
  • Multiple views: book, code and preview view
  • WYSIWYG editing in book view
  • Table of contents generator with multi-level heading support

A free SIGIL walkthrough, guiding you step-by-step through the process of creating an ebook first as epub and then as mobi file for Amazon’s KDP (Kindle Direct Publishing), starting from a text written in any word processing program (Open Office, MS Word, Pages, …).

I have used this process myself to create my own ebooks as an independent writer. I am very grateful for all the support I have been receiving from other independent writers in facebook groups and via direct contacts. The  free SIGIL walkthrough, written by Barbara Krauß in German was particularly helpful for me.

So now its my turn and I have translated it into English and added my own experiences in the process to share it with you.

On the internet there are many how to-books about, explaining how to create ebooks and how to upload them to portals like Amazon and many more. Most of them have been published as ebooks themselves and are out there to be bought.

You will find many good tips in them with respect to marketing, taxes, and many of them are worth their money and a lot of them go for € 0,99 or even $ 0,99 – so you cant go really wrong in buying them.

If you are looking for support to create a clean epub-file, which then can be easily converted into a mobi-file, then you are right here. This free walkthrough guides you through creating an epub-file with the freeware SIGIL and shows you how to easily transform a text-file into an ebook-file.

You do not need to know anything about HTML-code before to do this – I didn’t. :) Because this is what SIGIL basically does for you: it translates your text automatically into HTML-code, which is the base of ebook-files.

This walkthrough is a gift to you. I am grateful to be part of the international online community of independent writers and received great support in the manifold and diversified forums and groups, I am part of. Now I’m glad to offer such support to you.

Announcement:

We do not claim that we cover everything in this walkthrough. Everybody is responsible for creating his or her own ebook. We accept no liability for possible damages.

You need:

An edited text in any word processing program The freeware SIGIL a separate style sheet the freeware CALIBRE a program to create a cover for your book the free Sony Reader App to check your epub-file the freeware epubchecker to check your epub-file the free Kindle-Reader-App to check your mobi-file

Los diccionarios son una herramienta para comprobar la ortografí­a de los documentos OpenOffice.org para las distintas variedades regionales del español en archivo .zip para Windows y para Linux.

Puedes hacer que OpenOffice.org vea el diccionario configurándolo manualmente. Basicamente lo que haremos es editar el archivo de registro de diccionario y hacerlo ver los archivos de Diccionario, Hyphenation y Thesaurus.

El primer paso es poner los archivos de diccionario en el mismo directorio donde OpenOffice los busca. En la configuración normal bajo el subdirectorio share

El archivo de registro de los diccionarios llamado dictionaries.lst se debe modificar para incluir referencias a los nuevos dicionarios. Este archivo contiene una lista de diccionarios que vienen registrados. Debes entrar el registro dentro de este documento el tipo de archivo, la clave del idioma y la clave de la localización.

Para instalar un diccionario mexicano se hará lo siguiente:

DICT es es_MX es MX

Para uno argentino:

DICT es es_AR es AR

Existen otros archivos como los aff los cuales también deben ser incluidos.

Yo acomode las entradas de dictionaries.lst en orden alfabético y reinicie la maquina antes de que OpenOffice aceptara la nueva configuración.

ProjectLibre

In our interview with Marc O’Brien, co-founder ofProjectLibre, we featured a tool with support for task management, resource allocation, tracking, Gantt charts, and much more. ProjectLibre is a good alternative to a commercial software product like Microsoft Project.

In December 2013, ProjectLibre released version 1.5.8, and a full rewrite of the codebase towards an Open Services Gateway Initiative (OSGI) modular architecture is ongoing. This will allow connector modules for better integration with enterprise solutions such as Enterprise Resource Planning (ERP).

ProjectLibre is a Java based client tool. During their 2014 Q1 this year, they will release version 2.0. It is not clear yet when the SaaS version will become available.

ProjectLibre was awarded InfoWorld’s “Best of Open Source” in 2013 and ranks in my personal top 3 favorite open source project management tools.
