Go back to 1975. The idea of a computer at home was something that only happened in Science Fiction books. When the Altair 8800 was introduced, not only could you have a computer at home–you could build it yourself!
For some “computer” is a bit liberal. Based on the Intel 8080, the “computer” supported some toggle switches and LEDs on the front panel. As Gates explains in this video, there wasn’t even any kind of interactive terminal.

Everyday a new application involving the seemingly miraculous material Graphene is announced. For example, being in the capacitor industry, I am asked often if my employer uses it. Before answering the question, I usually have to explain what Graphene is and the challenges in producing it.
The lack of supply and limited (real) commercial applications leads me to think of Graphene as Unobtanium… at least, for the near future.

Understanding what X2 or Y1 capacitors actually are and are not is important when designing them into an AC-mains connected power supply. Recently Electronic Products Magazine ran an article I wrote on the proper role of X and Y safety rated EMI Capacitors.
The X2 capacitor rating means different things to different people–except for UL. When I wrote this article to discuss some common misconceptions around what X2 Rated Capacitors are, and how they can be properly used.
In case the PDF reader doesn’t load, it’s on Page 20 of the November 2014 issue.

Fun with the meme generating. When it comes to adding decoupling caps, Make It So.
The Gecko Zero EFM32 Weather Station Evaluation Board from Silicon Labs is intended to show off the low-energy or energy harvesting capabilities of the EFM32 Zero. The ARM-based board has physical and cap sensitive buttons along with the LCD.
It comes pre-loaded with a demo program, which is the classic Space Invaders.
If you’re interested in more about the board, I wrote a road test of Gecko EFM32 on element 14. (Spoilers: I wasn’t impressed. Not a bad board, but rough development environment.)
This is my first year attending CES. Apparently, nobody told anyone here about the death of the trade show. As an enginerd, here is my perspective. First, if you’ve never been, this show is huge. Huge. You aren’t just walking around 100 or so booths. This thing is spread across 3 different conference centers in downtown Las Vegas.
With over 160,000 attendees, CES was spread across three massive convention halls. Nearly every company offering electronic products were on display. From Televisions to Appliances to Computers to Automotive Electronics to Wearables. Broken down below are highlights and pictures from the show, based on industry or application area.
“There is no Moore’s Law for passive components like capacitors, but relentless development is delivering the kinds of devices engineers need to deliver cutting-edge new products for modern living. Capacitors have for many years enabled electronic designers to manage energy within circuits and fulfill basic functions like filtering noise or harmonics, correcting power factor, stabilizing feedback circuitry, coupling/decoupling, interfacing between voltage levels, and storing energy. But the demands placed on these components continue to increase, as electronic devices are expected to be smaller, longer lasting, more feature rich and more robust.”
