The Magnus Effect
Ever wonder how this is possible? You’ve seen it in major sports around the world, from soccer to baseball, the deadly curveball. It’s pretty obvious just looking at it that it has something to do with spin, but how does…
Physical Properties of a MOSFET
In 1949 it took any computer more than 70 hours to calculate the value of PI up to 2037 digits, now your smart phone can do the same in less than half a second. This achievement is credited to the…
Introduction to Quantum Cryptography
In 1943, Admiral Isoroku Yamamoto, the greatest military commander of the Japanese navy, went to visit one of the front line bases to boost morale. The plan of his visit was communicated through an encoded message through the Japanese Naval…
Introduction to Quantum Mechanics: Particle or Wave?
If you’ve gone to engineering school or seen too much of “The Big Bang Theory”, you’ve probably heard someone say, with a semi-smug voice: “light isn’t a particle or a wave, it’s both”. After they’re done patting themselves on the…
Laser 101 – pt. 2: Terahertz
In the previous section on laser 101, we looked at how a laser works on an atomic scale. We discussed key concepts such as the important correlation between frequency, wavelength and energy. A quick recap is that energy is proportional…
Electronics 101 pt. 4: RL and RC Circuits
Previous posts in this series: Electronics 101: Voltage, Current and Resistance Electronics 101 pt. 2: Kirchhoff’s Laws Electronics 101 pt. 3: Applying the Laws If you’re unsure about how capacitors and/or inductors work, check out: An Intro to Capacitors An…
Taking a Course in Embedded Systems for Beginners
I recently took an online course on embedded systems to get a good introduction to microcontrollers and some practical experience working on an MCU The course is Embedded Systems – Shape the World: Microcontroller Input/output (check it out). It teaches…
Laser 101 – pt. 1: The Basics
Note: this text is meant as a simplification of laser physics. Laser, or Light Amplification by Stimulated Emission of Radiation (If we want to get technical about it), is a device that emits Light through an Amplification based on Stimulated…
An Intro to Boolean Algebra and Logic Gates – Part 2
In the previous part of this series we gave you an intro to Boolean algebra and Logic Gates, which incidentally happens to be the title of this blog post as well. This time around we’ll take things a bit further…
An Intro to Boolean Algebra and Logic Gates – Part 1
This is part 1 of a planned short blog series about Boolean algebra and logic gates. In this first part we’ll introduce you to simple Boolean algebra, which is very basic, and then look at how one or more logic…
Do It Yourself: SNMP Temperature Monitoring System
Here at Norwegian Creations we occasionally need to monitor the temperature of a system. Sometimes we have done this with our DMM with data logging capabilities. But it’s a bad idea to impound our DMM’s for long periods. Therefore we need…
Breadboard – What, Why and How?
Breadboard is an essential tool for every electronics engineer and maker. In this blog post we’ll talk about why we use breadboards and how they work. What? A breadboard is a simple tool which is used to easily connect electrical…
Datalogging with a Multimeter
A Digital Multimeter (DMM) is a nice tool which we have talked about several times before (you can find an intro on how to use it here). The main usage is to measure something right now. But how can we…
Opamps – pt. 2: The Real World
Two weeks ago we started a blog series about operational amplifiers aka. opamps (or op amps). We showed you what an opamp is, some of the things it can do and the importance of feedback. To ensure that everything was…
Opamps – pt. 1: The Basics
Operational amplifiers aka. opamps are electrical components that we haven’t previously touched upon in our blog. These components are important, though, so now we’re starting a series where we’ll introduce you to opamps and their usage. The opamp-topic can be…
