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…
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…
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…
State Machines and Arduino Implementation
When designing embedded systems, you more often than not should implement a proper state machine of some sorts. In this blog post we’ll explain what state machines are, compare a couple of types, look at the handy Huffman table and…
Do It Yourself: Bose QC15 / QC25 Bluetooth Module
The newest Bose noise cancelling headset, the QC35, has wireless Bluetooth connection. They are also quite pricey. Many already own a pair of QC15 or QC25. If you’re one of these people and want to upgrade to wireless connection without…
Using a Logic Analyzer: An Important Tool in Every System Designer’s Toolkit!
A Logic Analyzer is an instrument that records (and displays) multiple digital signals. This instrument gives you several important benefits, such as timing analysis and protocol decoding. You can also get more “general assistance“, often in the form of clever signal triggering,…
Embedded Tutorial: Basic Serial Communication
If you’re going to design embedded hardware you have know your way around the most common wired digital communication protocols and standards. These protocols and standards define how different parts of an embedded system communicate with each other, for instance…
An Intro to Digital Multimeters (DMMs)
Here at Norwegian Creations we use digital multimeters (DMMs) a lot. In fact, this is an essential tool to have if you want to play with electronics. In this blog post a brief introduction and operation of a digital multimeter…
Double Exponential Moving Average Filter – Speeding up the EMA
Sometimes you have a noisy signal which you want to low-pass filter to a less noisy signal. The Exponential Moving Average (EMA) filter is a nice and easy filter to implement on your embedded system. Read more about the EMA…
