PCB layout is tough. Laying out a PCB isn’t in itself too hard once you learn how the tools work, but high-speed (10MHz+) introduces a virtual mine field of potential issues that you may not be aware of until it’s too late. While experience is the best teacher, Analog Devices has a great application note explaining some of the key pitfalls to avoid when dealing with high speed designs (which is basically anything today): A Practical Guide to High-Speed Printed-Circuit-Board Layout. Some of it is a bit heady, but not more than it needs to be, and it really does lay out a lot of key information that you may not have been aware of. Want to improve your PCB design skills? Print this out, and keep reading through it until it starts to make sense. There’s years of bench time worth of information in there.

Electronics design engineers across the globe are burdened with lengthy and disparate design processes – from concept to pre-production – all-while balancing the need to bring products to market faster. In short, the ability to save hundreds of hours in the design process is critical to advancing designs.
As part of an ongoing effort to better understand the needs of design engineers, element14 today unveiled findings from a global study conducted by TFI looking at the critical challenges throughout the design process. The study revealed several pain points – increasing time pressures, incomplete/inaccurate information from relevant sources, and difficulty comparing options. Additional findings include:
- Over 70% of design engineers rely heavily on online forums, blogs and engineering communities
- Engineers spend about 50% of their research time online
- A majority of respondents cited the earlier stages of design as the most challenging (consuming an average of 41% of design time)

The secret world of oscilloscope probes – [via]
The oscilloscope is an essential tool for anyone working in electronics. Whether you’re working in electronics service, production, testing R&D or in your home workshop, you need an oscilloscope. If you listen to a bunch of technical people chatting about their scopes, they’ll talk about their bandwidth or whether they have colour displays, depth of memory or portability but the probes rarely get mentioned. In fact, most users don’t think about their probes until they hear the sickening crunch underfoot which tells them they shouldn’t have left them dangling off the bench onto the floor. There are many varieties of “specialist” probes: active-FET probes, differential-floating probes, current- sensing probes are just some we could mention.

We live in a world where the accumulation of knowledge is exponential over time, and where the ability to continuously learn and make sound judgments is essential to survival. Formal education ought to play an important role in preparing individuals to succeed in this environment, but many traditional modes of education actually discourage development of independent thinking skills necessary for success.
The most important thing any educator can impart to a student, in any context, is the ability to teach themselves. When teachers dispense knowledge to students in the traditional lecture format — where students passively watch and listen — they deny students deep interaction with the subject matter. Furthermore, instructor-centered pedagogy assumes and reinforces the debilitating notion that education can only happen in the presence of a superior: You (the student) need me (the teacher) in order to learn.

Free license study guides
Dan KB6NU writes:
Currently, I offer study guides for the first two license classes, the Technician Class and the General Class, and I’ll be publishing a study guide for the Extra Class license next year.
I call them “no nonsense” license study guides because all I cover are the questions that might appear on the test. The philosophy behind this is that the quicker someone gets a license, the sooner they’ll really be able to learn about the hobby, whether that’s electronics or antennas or propagation or whatever.
The study guides are available in three different formats:
- FREE! There’s a free PDF download available from my website.
- E-book. There are Kindle and Nook e-book versions available from the Amazon and Barnes&Noble websites. The cost for the e-book version is $7.99.
- Print. Yes, a dead tree version is available if you really want one. These cost $12, shipped, and are also available from my website.

This book will show you how to use your Arduino to control a variety of different robots, while providing step-by-step instructions on the entire robot building process. You’ll learn Arduino basics as well as the characteristics of different types of motors used in robotics. You also discover controller methods and failsafe methods, and learn how to apply them to your project. The book starts with basic robots and moves into more complex projects, including a GPS-enabled robot, a robotic lawn mower, a fighting bot, and even a DIY Segway-clone.
- Introduction to the Arduino and other components needed for robotics
- Learn how to build motor controllers
- Build bots from simple line-following and bump-sensor bots to more complex robots that can mow your lawn, do battle, or even take you for a ride
