The new version of Eagle is on out! The biggest changes coming are a new design feature and an improved autorouter. We are both veterans of Eagle and PCB board design so this blog is intended as both a review and a tutorial of the new features that Eagle v7 brings. Let’s dive right in.
To make the design process more real, we decided to design a circuit from scratch. A simple circuit that Sophi has worked with is one that uses an audio signal to control a hobby servo, which could be used to control an animatronic. It’s a little early for Halloween, but Sophi had used this circuit before and planed on using it again in October. Many thanks to Scary Terry who gave us permission to use his design.

The award winning EAGLE is a powerful and flexible PCB design software offering high level functionality of expensive commercial circuit board design software at a fraction of the cost for over 20 years. EAGLE offers the three modules: Schematic-Editor, Layout Editor and Autorouter embedded on one single interface. EAGLE is easy to learn, easy to use and easy to buy. It runs on Linux, Mac and Windows and allows feature enhancement, such as simulation, 3D-visualization, data import and export and self defined commands, through User Language Programs (ULP’s) which are partly integrated in EAGLE and available at the download area.

Mentor Graphics, in conjunction with Digikey, has announced the public beta of their $299 Designer Schematic, joining companies like CadSoft (Eagle), RS (DesignSpark), and DipTrace in offering entry-level software in the triple-, double-, or even single-digit price range. Designer Schematic is a scaled-down version of DX Designer, and features integration with Digikey’s massive part inventory.

Every electrical engineer who does DIY projects knows that dozens of free resistor calculators are out there that can save quite a bit of tedious work. Other simple tools can be found, but traditionally the free tool arsenal would stop there. Sure, there are base platforms such as SolidWorks and Autodesk, but what happens when they are missing a feature needed at that exact moment?
Now we’re seeing a relative explosion in free tools for engineering electronics. It is easy just to hit the Net and use the myriad resources available. Some of those online tools prove to be worthless, and it’s back to blind searching or some paid tool, but free software extends far beyond the functionality of a simple calculator.

Workshop Organizer is light-weight, cross platform inventory controller for home-workshops. This application is specifically design to manage electronic/electrical components at home-workshops, but it can use to manage other areas of workshop including tools, machinery and mechanical components, etc.
To store data, this application use SQLite database system and all the necessary runtime libraries for SQLite is available with the “Workshop Organizer” package. User may not need to download or install separate SQLite database system to use this application. Workshop Organizer default SQLite database consist with more than 600 reference data including list of manufacturers and types.

MikroElektronika today announced that May 6, 2014 marks the 10th anniversary since it started developing compilers for Embedded programming – mikroC, mikroPascal and mikroBasic. The company will celebrate the occasion with a month long campaign that will include exclusive content, discounts and weekly full compiler license giveaways.
The successful release of mikroPascal for PIC in 2004 spawned an extensive product line that today has 18 compilers for six popular MCU architectures (ARM, PIC, dsPIC/PIC32, 8051 and AVR) that had a significant impact on the embedded electronics industry.

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.

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
