How To Design Internet Of Things Devices: Make Them Simple and Universal
Greed is a natural human tendency that promises much but often leaves us with nothing. My father grew up in a gold rich area of Africa. A miner once told my father and his friends that they could keep as much of his gold as they could carry by hand for 5 miles. My father and his friends each took their turns, but all of them tried to carry too much and couldn’t even make it one mile. The temptation to attempt too much, or keep too much to oneself

The SpaceX Hyperloop Pod Competition: Growing the Next Generation of Electronics Designers
In 2013, when Elon Musk unveiled the concept of the Hyperloop as a future form of transportation, he immediately challenged private industry and universities from around the world to develop the technology and pods. (After all, he has his hands full these days!) Since that time, SpaceX has hosted two Hyperloop pod competitions consisting of university teams at their headquarters in Torrance, CA. These events afford three lucky teams the chance to

How to Reduce Power Consumption in Embedded Systems With Deep Sleep SRAM
Editorial credit: DFree / Shutterstock.com One of my favorite musical groups is the French DJ duo Daft Punk. One of the quirks of Daft Punk is that they pretend to be robots and perform all their shows in awesome robot costumes. In 2013 they released their album Random Access Memories, or RAM, to play on the robotic theme. However, they failed to specify exactly which kind of RAM. You and I know that in the world of embedded systems the type of

SpaceX’s Hyperloop Pod Competition: The Pod Flight Heard Around the World
Judy Warner and Benjamin Kitzinger of Altium If I had any question I am a total geek, all doubt was dispelled yesterday when I entered the gates to the Hyperloop Pod Competition II held at SpaceX headquarters in Torrance, California. I felt exactly like a giddy 8-year-old clearing the turnstile at Disneyland for the first time. Then, when the WARR Hyperloop team set the new pod world speed record, at 324 km/h ( just over 200 mph ), I nearly

Cooling Your PCB: Overview of Passive PCB Heat Dissipation Techniques
Have you ever been so hot you thought you might melt like a popsicle? Summer down here in SoCal gets pretty toasty and makes me wish I had a few freezes pops. When I get home from work I love to blast the AC and pretend that I live in an igloo. However, the only thing worse than boiling in the heat is seeing all my money evaporate away in cooling bills. Other people take a different approach to cooling PCBs; they use geometric shapes or heat

A Comparison of Active Cooling Techniques for Electronic Equipment
Cooling of electronic equipment is pretty important. I know this because part of my laptop’s motherboard melted once. I bought a new top-of-the-line computer back in 2010 to try out a new graphics-intensive video game. It came with an amazing graphics card, but an undersized thermal management system to hang. I should have known there was a problem when the keyboard got too hot to touch when I started playing games. Soon afterward, my computer

How IBM’s 5 nm Transistors Will Enable Internet of Things Deep Learning and Other Technologies
My great-grandmother was born at a time when normal people still used horses and carriages to get around. By the end of her life, she had seen jet airplanes, computers, and spacecraft. Technology in the last century accelerated rapidly, and this century promises more of the same. Moore’s Law has been one measure of the pace of advancement. While many experts have predicted its doom, Moore’s Law stands today. The most recent proof of electronic

How to Choose the Best PCB Reflow Oven for Efficient PCB Solder Assembly
Whether you’re an electrical engineer or an electronics hobbyist, solder reflow ovens enable fast and convenient printed board (PCB) assembly. If you have assembled dense PCBs with many small surface-mount components or used ball grid array (BGA) devices in your designs, you have undoubtedly come across solder PCB reflow ovens. While the ambitious hobbyist may choose to build a toaster oven “reflow oven” , many businesses can save time and

How to Setup and Interface with WS2812B LEDs for PCB
Are you in the mood for a good laugh? Well, I have a story for you. I’m a design engineer with decades of experience, but a LED project recently almost brought me to my knees in despair. I used to think that LEDs were as simple as getting the light emitting diode connected to a limiting resistor and a power supply. Aren’t they? That’s exactly what went through my mind as I worked on an architecture model lighting project a couple of years ago. On

2018 Olympics: Intel Will Showcase Future PCB Technology in Electronics and Communication
Editorial credit: lazyllama / Shutterstock.com I love watching the Olympics. It’s exciting to see the best athletes from each country test their skills against one another. The Olympics are also a forum for host countries to showcase everything that they’re capable of. In the 2018 Olympics countries aren’t the only ones who will be showing off. Intel recently announced a partnership with the International Olympic Committee (IOC) that will let

How to Perform In-House Pre-Compliance Testing for Radiated Emissions
Sometimes you can feel like you’re putting out good vibes, but you’re really emitting something else. The same goes for wireless circuits. You go through the design and immunity testing, then send your board off to an EMC lab only to find out your board is radiating the electronic equivalent of garlic breath. Performing in-house hardware pre-compliance testing can help you avoid a costly rejection. You’ll have to spend some money on equipment

Conducted Emissions Test Equipment and Noise Reduction Guidelines
One of my classes in college was so difficult that the professor would give us the test questions a week in advance. Even knowing exactly what to study for the exam, lots of students still failed. Conducted emissions analysis for electromagnetic compatibility (EMC) is similar. Devices need to be checked to see if they’re putting too much noise back into the grid through their power supply. Otherwise, the FCC will think you’re disrupting utility

How FRAM Memory Simplifies Embedded System Data Logging
I’ve always found it easier to make decisions when the options were clear-cut. Choosing between black and white, right or wrong, you could make your decision and never regret it. However, decisions that involve picking black, white, or one of many shades of gray really stress me out. I was happy abiding by my binary logic until Ferromagnetic Random Access Memory ( FRAM ) came on the commercial market and I was forced to embrace one of the shades

Massive MIMO Benefits for 5G Cellular Infrastructure
Editorial credit: PureRadiancePhoto / Shutterstock.com Even though I ended up here in southern California, I was originally born in Texas. We have a saying that you probably have heard, “everything’s bigger in Texas.” That turned out to be true for me, as I’m the tallest member of my extended family. I’d like to think that the minds behind massive multiple input multiple output (MIMO) antenna arrays were also born in Texas. MIMO has been around

IoT Storage Technologies: Ultra Low Power CBRAM
Do you remember using those old floppy disks back in the day? I remember my computer had two floppy disk drives. You’d put the disk with your program in one and a disk for the data in the other. Eventually, the incredible invention that is the hard drive came about and storage space exploded. Our memory capacity is still increasing, but now the size is becoming less of a factor. When it comes to the Internet of Things (IoT) energy usage is the

Why Wearable Technology is the Future and How It Will Be Seamless and Convenient
When I was younger I was a bit of a nerd, and I guess I still am. The most visible sign of my nerdiness was my fashion sense or lack of it. Tall socks, cargo shorts, and a brown Pacman hoodie that I wore in every season, except summer, made up my daily wardrobe. I was simply more interested in gizmos and gadgets than I was in looking good. I’m still more interested in fashionable electronic devices than clothes, but the line between the two is
