Morse View is an open source software project to convert audible Morse codes to text messages. This application is capable to convert Morse codes from wave files or from the audio line/microphone inputs. Conversion from Morse code to text can perform based on amplitude and frequency decomposition of the input audio stream.
We extensively test this application using Morse code files available at ARRL – W1AW code practice page. During the testing we may be able to use this application to decode 5WPM – 40WPM Morse code inputs.

Sockulator

desmith.net hosts a nice little script to generate socket footprints for various CAD packages:

This program lets you determine the pin circle diameter of a tube base from measurements more readily made with a micrometer. The data should be entered in millimetres and the results will be in the same units.  Script output for a package definition of the resulting socket can be generated for several CAD packages. Create a disk file from the output script and execute it in the relevant package – for Eagle execute the script as a SCR from the library editor.

Gerbv is an open source Gerber file (RS-274X only) which runs under Windows or Linux.

Gerbv lets you load several files on top of each other, do measurements on the displayed image, etc. Besides viewing Gerbers, you may also view Excellon drill files as well as pick-place file

I got my first taste of programming with RCX Code and an old Mindstorms RCX 1.0, so maybe it’s nostalgia speaking, but I really admire visual programming languages for their ability to introduce younger folks to programming. With color coded operators, geometrically shaped data types, and no semicolons (!), visual languages have a unique ability to make programming a more intuitive experience. And with the (admittedly necessary) annoyances of syntax removed, more of your programming focus can be directed towards solving the actual problem.

DesignSpark-Mechanical-3d-software-1

A new, free 3D design tool aims to help engineers with 3D modeling of their designs by being easy to use. RS Components and SpaceClaim joined forces to develop the tool, which can be used to model physical elements of designs, such as enclosures or interface panels, without having to learn complex feature-based 3D tools. It can also be used to develop early prototypes, either as a PDF file or on a 3D printer.

DesignSpark Mechanical aims to overcome the two major entry barriers faced by potential users: the cost and steep learning curve of traditional 3D CAD tools. DesignSpark Mechanical is free, and it uses direct modeling so that engineers and others involved in product development can learn to use the software within minutes. [via]

codebender_editor

Traditionally, you would need to install an IDE, which includes all the necessary software, find and install the correct drivers, set permissions, etc. It can take 10-60 minutes. Or it can be a total mess.

With codebender, you can program your Arduino straight from your browser. No need to find, install, update and manage libraries and drivers. codebender does that for you. Just install our browser plugin and follow our Getting Started guide. From having an Arduino, to having a programmed Arduino. In mere minutes.

After installing the pluggin, you can flash any codebender sketch to your device. See the code bellow? You could load that to your device, straight from this page!

OMG! All the electronic and mechanical engineers I know (and even most of the marketing folks) are going to squeal like schoolgirls when they get their sticky little hands on this amazing, free 3D design software that will enable conceptualization and rapid prototyping, reduce costs, and dramatically accelerate product development. In short, this software is like a “Gift of invention that will bring your ideas to life!”

Quiet down my racing heart! I just heard the most amazing “hot-off-the-press” news. In just a few days as I pen these words, all of us who wish to will be able to design 3D models, assemblies, and enclosures for our designs using some incredibly intuitive, fully-featured 3D modeling software. And, best of all, it’s free! (And when I say “free” I really mean free, as in free for both commercial and non-commercial use with no limitations or licensing.)
