When it comes to schematic capture and circuit simulation on a mobile device, iCircuit for iOS got it right from the start. iCloud integration, intuitive touch controls, and fast application performance. Now (or Finally?), iCircuit is available for OS X.
iCircuit is based on the Falstad Circuit Simulator, which sadly, is a Java-based web app. For years I’ve installed the App on my iPhone and iPad almost immediately after turning on iCloud [for Android users, that’s basically the first step of activating an iOS device].
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.

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.
