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"

The Old Man and the C Debugger

“Eliminate all other factors, and the one which remains must be the truth.” – Sherlock Holmes, The Sign of Four

Three engineers are sitting in a rowboat. None of them has any nautical experience or navigational instruments.

As hope for rescue fades, and with no other ships in sight, they pass the time discussing their careers (as … Read More → "The Old Man and the C Debugger"

Will Cars Be a MEMS Sensor Bonanza?

OK – quiz time: what do you think the top three upcoming applications for semiconductors are going to be?

If one of the categories you named wasn’t “automotive,” then you’re not doing your part in the echo chamber. (And you didn’t read the title carefully.) Everyone knows that Christmas is coming to the electronics world as cars convert … Read More → "Will Cars Be a MEMS Sensor Bonanza?"

Security from the Ground Up

It takes 8,460 bolts to assemble an automobile, and one nut to scatter it all over the road.  – Author Unknown

Hello, my name is Amelia and I have read at least four hundred press releases about automotive design this week. It seems that this year’s Consumer Electronics Show has been taken over by automotive design. But behind the pomp and sparkle of CES lies the … Read More → "Security from the Ground Up"

Baby You Can Drive My Rover

“Beep beep’m beep beep yeah,” – John Lennon and Paul McCartney

While several companies are expending significant resources and large amounts of energy to develop automated driving for passenger vehicles, trucks, and buses here on Earth, a dedicated group of scientists and engineers at JPL (the Jet Propulsion Lab) have been working on a related but significantly different problem: creating autonomous driving … Read More → "Baby You Can Drive My Rover"

Interesting concept. You might want to re-think titanium. It may certainly true that in the 1970s', one would have used 7% of the world supply of titanium to create a 100MW heat exchanger. However, today, and based on Google search, it is the 9th most abundant metal in the earth's crust. ...

Very interesting story. You should know that the genesis of the algorithm used by the Mars Rovers (as well as by Google Maps, the DARPA Grand Challenge, and many other autonomous devices) is SHAKEY the Robot, as developed at SRI from 1966-1972. With great help from Peter Hart, I led ...

What do you think of USound's MEMS speaker approaches?
Posted on Jan 3 at 2:57pm by Jim Turley
All fair points, but the compliance testing will be both (a) mandatory and (b) pretty cheap. It's not a profit center for anyone; just a way of ensuring that anything bearing the MIPS name really does implement the architecture correctly so it doesn't become a free-for-all. I would imagine that ...
Posted on Jan 3 at 11:52am by Steve Hoover
Hi, Jim. Free MIPS would be great, but the compliance testing requirement sounds like a big deal. There's a bigger difference between free and cheap than there is between cheap and expensive. I can't see MIPS crawling from the coffin unless all the dirt is cleared. Do you have any ...

SimSurfing — Murata and Mouser Electronics   Choosing the right passives for your design can be a huge headache. Sorting through hundreds of data sheets looking for the component with just the right specs, balancing against your BOM requirements, and confirming availability can consume valuable engineering time. In this episode of Chalk Talk, Amelia Dalton chats with Arthur Evans of … Read More → "SimSurfing — Murata and Mouser Electronics"
ST-Teseo LIV3F GNSS Module for IoT Positioning — STMicroelectronics and Mouser Electronics   Many IoT designs these days need location capabilities. While GPS alone was great in the old days, a modern design should be compatible with other satellite constellations as well for maximum performance. In this episode of Chalk Talk, Amelia Dalton chats with Mike Slade of STMicroelectronics about the Teseo-LIV3F Module which can make … Read More → "ST-Teseo LIV3F GNSS Module for IoT Positioning — STMicroelectronics and Mouser Electronics"
Migrating from 3G to LTE — Digi International and Mouser Electronics  If your company infrastructure is converting from 3G to LTE, you’ve got a lot to think about.
