Since my last article, I’ve been trying to decide on CAD tools. I originally suggested EAGLE but it has been purchased by AutoDesk and they require a yearly subscription for 4-layer PCBs. I intend to create only 4-layer PCBs to make layout easier per the suggestion in Michael Ossman’s video. I also believe electrical engineering needs to move towards open-source tools like the software community. Consequently, I started learning KiCAD, which neckbeards argue over how to pronounce. It’s a free hotkey-based CAD tool with significant recent contributions from CERN that runs on Linux, MAC and Windows.Read More

Newly discovered deep ties between the chief investment officer (CIO) of the California Public Employees Retirement System (CalPERS) and the Chinese government, along with CalPERS’s China investment holdings, have provoked controversy about the operations of the largest public retirement fund in the United States.Read More
In some cases, our competitive edge has not just been eroded, but is at risk of being—or already is—surpassed. The Chinese surge in 5G telecom equipment, which has dual civilian and military uses, is one example. China is making key investments in artificial intelligence, another area of competition. They even seem to be able to mount a rail gun on a naval ship, an important next generation weapons technology that the U.S. Navy has yet to incorporate.
And yet, the U.S. military budget, even at stalled levels, is still larger than the next nine countries’ budgets combined. So there’s a second natural follow-up question: is the defense budget the primary reason our military advantage is slipping away, or is it something deeper?
The story of Huawei, and many others, suggests the latter.Read More
RF design is a black art for several main reasons: textbooks, Smith charts, CAD tools and components. Academic texts on the topic are expensive, full of mathematical formalism and written by men with no practical experience...Read More
