Wearable Technology in the Future 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 electronic devices than clothes, but the line between the two is beginning to

Badgerloop’s Run for Hyperloop Glory Captures the Attention of Elon Musk
Team Badgerloop at the June Pod II Reveal In 2013, Elon Musk introduced the concept of a Hyperloop transit system in a white paper . He proposed a completely open source approach to its development and invited universities to participate in a pod competition. SpaceX funded the construction of a near-mile subscale version of a vacuum tube in which to trial pods for the competition. For the first competition, only 3 pods would earn an opportunity

How Smart Tech Electronics Is Used for Combat Against Parkinson's Disease
This past week I went home to Toronto to visit my parents. My grandfather, who is 87-years-old was recently diagnosed with old age dementia and had his driver’s license taken away. While my family was relieved to have him off the road, he was devastated by the loss of independence. That, however, changed one day when I went to pick him up from his house. I arrived to find the house empty, but his car was still in his driveway. It turns out that

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 size is becoming less of a factor. When it comes to the Internet of Things (IoT) energy usage is the next

How NASA Plans to Use 3D PCB Technology and Designs for Space Missions
Editorial credit: Tony Craddock / Shutterstock.com Have you noticed how a 3D model has become a phenomenon? People seem to want to 3D print anything they can now. Maybe the 3D printing craze will collide with the Internet of Things and we’ll get a printed smart fork . While other people are writing about the 50 best things you can make with them and then throw away, I’m going to tell you how NASA hopes to use 3D printing. Between a rocket

How to Use a Ferrite Bead in Your Design to Reduce EMI
EMI and EMC can be a tricky subjects, and it's often tempting to mis-apply design guidelines to try and reduce EMI. One of these areas relating to EMC in PCB design is the use of ferrite beads. These components are basically filters, and they do perform a useful function on power cords in many electronics. You're probably reading this article on a laptop that uses a ferrite to filter out conducted EMI from the supply line. A problem begins to

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 or 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 of

How Do Ferrite Beads Work and How Do You Choose the Right One?
Sometimes, I wish I could see electromagnetic waves. It would make detecting EMI much easier. Instead of having to mess around with complicated setups and signal analyzers, I could just look and see what all the fuss is about. While we may not be able to see EMI, we can sometimes hear it when it comes through audio circuits. One possible fix for that kind of interference is a ferrite bead. Unfortunately, ferrite beads (also called a ferrite choke

How to Prepare Your PCB for Outgassing in Ultra-High Vacuum Systems

How to Setup and Interface with WS2812B LEDs
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

How Parasitic Inductance Can Impact Your ESD Protection
When I was a kid, I was certain I was going to be a biologist. I collected all kinds of lizards, tadpoles, and insects, and spent most of my allowance on aquariums for my various creatures to live in. However, one thing really held me back. I am super grossed out by parasites. I will let a mantis or snake crawl all over me, but even looking at a tapeworm gives me dry heaves. Eventually, I went into engineering, where nothing needs weekend

How to Choose a Solder Reflow Oven for Efficient PCB Assembly
Whether you’re an electrical engineer, like me, or an electronics hobbyist, solder reflow ovens enable fast and convenient printed circuit 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 reflow ovens. While the ambitious hobbyist may choose to build a toaster oven “reflow oven” , many businesses can save

How IBM’s 5 nm Transistors Will Enable Internet of Things Deep Learning and Other Technologies
My great grandmother was born in 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

Meet the Baja Racing Team from New Jersey Institute of Technology
Bob Burghart is a Sophomore who is studying Mechanical Engineering at NJIT, and is the leader of the sub-team responsible for electronics designs for their Baja racing car. In the car, there is a main dash system, a data acquisition board, a display board, and front and rear dongles that connect to 20 sensors. As a kid, Bob had the typical curious mind of a budding engineer--always enjoying taking things apart. By middle and high school he began

Advanced PCB Design Solutions Require Short and Long Term EDA Software
My grandfather taught me to always use the right tool for the job. He told me that because I broke one of his screwdrivers while using it as a pry bar. Sorry grandpa. You might not break something by using the wrong apparatus, but you are guaranteed to take too long finishing your work. The same principle applies to PCB design. As boards becoming increasingly complex, designers need more advanced tools to build them. You can try working with the
