Staying Too Long at the Faire

It’s a sad day. Maker Media, Inc. ceased operations this week and laid off all staff. The company published Make: magazine and operated and licensed “Maker Faires” around the world. We have covered the maker movement and Maker Faires for years, even though our audience is professional engineers. We saw value there. Maker Faire was a window into the future of engineering – a place where we could go … Read More → "Staying Too Long at the Faire"

Extracting Power from Seawater without Nuclear Fusion

Every once in a while, I find it refreshing and stimulating to stop thinking about circuits and to ponder where we will get all of the electricity to power those circuits in the coming years. During a recent trip to the big island in Hawaii, I got a reminder. My wife and I visited NELHA, the Natural Energy Laboratory of Hawaii Authority, located between the ocean … Read More → "Extracting Power from Seawater without Nuclear Fusion"

Tons of LEDs – One at a Time

It just seemed so wasteful to him! All he needed was a thin coating of flour on the chicken, but the only way to do that was to dredge the piece in a pile of flour. Like, about 100 times more flour than he really needed. He could reuse the flour for any other pieces, but, once you were done for the night, he’d be throwing away more … Read More → "Tons of LEDs – One at a Time"

AI Meets AC/DC

“For those about to rock, we salute you.” – Brian Johnson

Let’s play a game! First, we’ll divide the players into two teams. The first team includes fluffy kittens, nuns and orphans, baby ducks, and Delta blues guitarists. The second team includes patent trolls, the Ebola virus, personal-liability lawyers, and Brussels sprouts.

Which team does … Read More → "AI Meets AC/DC"

Full-Power WiFi at Half the Power

In IoTland, communication is king. It puts the Internet in the IoT. But how to communicate? LTE? BlueTooth? WiFi? It partly depends on the application and the location, but it also depends on how far you are from a wall plug.

Because many IoT devices are small, portable, and – this is key – battery-powered, they will forever be infinitely far away from the wall plug. While WiFi has … Read More → "Full-Power WiFi at Half the Power"

As we seek to go faster and faster in our systems, heat grows as does the noise from the cooling fans. It is because of this heat and noise, many companies are investigating or switching to submersible cooling (liquid immersion cooling) options. Over the last few years, subme...

[From the last episode: we looked at how intellectual property helps designers reuse circuits.] Last week we saw that, instead of creating a new CPU, most chip designers will buy a CPU design '€“ like a blueprint of the CPU '€“ and then use that in a chip that they'€™re...
