In this introduction Dave explains what LTSPICE is and how to do the simplest of the SPICE analysis options – basic DC operating point analysis. Also how to draw basic schematics, display voltages and current on your schematic, and a beginner few traps to avoid.

MegunoLink Pro is a tool designed to aid embedded electronics designers. From hobbiests using the Arduino platform to commercial engineers using PIC or TI micros. MegunoLink provides a set of tools to help visualize serial data and investigate what is going on inside that piece of silicon. MegunoLink is made up of a set of visualizers that each have a unique function and any number of them can be utilized at once. With these visualizers and our functional tabbed and docked interface you can create a full control center for your embedded project. Plot, log and monitor serial streams from both hardwired, bluetooth, and network based (UDP) devices.

Jérôme Vuarand developed an application to visualize Gerber data, a simple 3D viewer for Gerber files. This tool helps to review Gerber files before sending them to a PCB fab house:
Over the course of the last 5 months I developped an application to visualize Gerber data. The goal was primarily to review Gerber files before sending them to a PCB fabrication house. It is very similar to the Mayhew Labs online Gerber viewer, except it’s offline (and has a few different features).My tool is program for Windows (32bits or 64bits) that use OpenGL for visualization (you will need a decent/recent video card). You can simply drag and drop Gerber files on it, or use the command line to configure it more deeply. I set up a page explaining most of that and giving download links

Apple this week is celebrating the five year anniversary of its Apps Store. If you go to the store, you’ll notice Apple is giving away five games and five apps to celebrate the anniversary.
When it opened its virtual doors, the Apps Store did so with a mere 500 apps. Now, it showcases more than 900,000, with more than 800 apps being downloaded each second.
In total more than 50 billion downloads have taken place since the Apple App Store’s 2008 launch, with more than $10 billion being paid out to developers.
Mixed in among the whopping number of available apps are a few that engineers, specifically, might enjoy. We’ve created the following list of our own favorites as well as some contributed by engineers in the field.

AT command tester is a free online software tool that is used to test AT commands and other functionalities of GSM modems. The friendly user interface allows developers to,
- Configure and connect to modem ports
- Send single or batch of AT commands
- Perform modem diagnostics
- Establish 3G or GPRS call
- Collect and save modem logs
AT Command Tester uses Java-based serial drivers to interface to the modem. The ‘Find Ports’ button will automatically find all ports available in the system. The user can connect the appropriate modem port with the desired port speed.
After connecting successfully to the modem, users can send single AT commands under ‘Command Mode’ tab. The drop down provides list provide list of AT commands with description and examples. The users can modify or enter their own AT command in the text box. Read the rest of this entry »
Javier Serrano of CERN’s BE-CO-HT section has sent this message to the Developers list to help enhance Kicad: Introducing CERN BE-CO-HT
As you know, the BE-CO-HT section at CERN has been contributing to Kicad for some time now. We see this involvement as a key part of our activities regarding Open Source Hardware. We are also contributing to the adoption of VHDL and SystemVerilog in the Icarus Verilog simulator, so as to enable cross-language simulation. Other related activities include the operation on the Open Hardware Repository and the development of the CERN Open Hardware Licence

Analog Devices, Inc. (ADI) released a new version of its popular ADIsimRF design tool:
The free design tool is the software accompaniment to ADI’s complete portfolio of RF-to-digital functional blocks, allowing engineers to model RF signal chains using devices from across ADI’s RF IC and data converter portfolio. ADIsimRF Version 1.7 adds a number of new device models along with enhanced support for inter-stage mismatch calculations. The design tool provides calculations for the most important parameters within an RF signal chain, including cascaded gain, noise figure, IP3, P1dB, and total power consumption. The ADIsimRF design tool contains embedded data from many of ADI’s RF ICs and data converters, which designers can easily access using pull-down menus to assist in component selection.

A new PCB design web application was released this last week called PCBWeb. The website states that PCBWeb is a free browser-based CAD application for designing and manufacturing electronics hardware. The tool is currently released in BETA and allows you to create a schematic, full circuit board layout, and then export to gerber format for manufacturing. The application is supported on Windows and Mac using Silverlight.
