In this “Will It Blend?” Tom takes on neodymium magnet balls. This is a fun one to watch because the balls spark up while flying around. Some really good slow motion replay work here.
If you aren’t familiar with “Will It Blend”, it is a video series presented by the blender maker Blendtec. Tom Dickson attempts to bend various items. Not only the star of the clips, Tom is also the Founder of Blendtec. You can find all their videos at willitblend.com.
Karl and Corey run The Spark Gap Podcast which is focused on embedded electronics. On Episode 25 they interview me about Capacitors. We covered all the major types of caps, plus some application bits. Check out their show notes for an impressive array of links on the subject.
Also, my favorite episode of theirs so far is episode 18. The guys talk about different serial protocols like SPI, I2C, CAN, etc. Really good stuff.

Capacitor Questions Answered on The Spark Gap Podcast
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.
