## A walk down the low-cost MCU-road

Introduction Some projects here at Norwegian Creations involves MCUs with a good selection of internal modules in hardware. But sometimes cost is very(!!) important, and much other things are not (how much RAM does your headlamp need?). So in cases…

## Calibrating a Torque Wrench

In this post we will show you how you can calibrate a Torque Wrench. Here we calibrate a SMA Torque Wrench, but the method shown here are applicable to common Torque Wrenches. Can it be calibrated with a kitchen scale?…

## 3D-printing and finishing

When 3D-printing, you typically get visible layers. These irregularities is often desirable to hide. In this post will show you a method you can use to conceal them and finish the part. The Subject and the Plan The model used…

## How to go from an irregular form to a technical illustration

A common challenge is how you can go from a free hand drawing to a more technical correct illustration. In this blog post we are going to show you a process you can use to go from a simple hand…

## Measuring Frequency With a Digital Multimeter

We have written about using regular Digital Multimeters (DMMs) to measurements common things such as Voltage, Current, Resistance and much more. Those post can be checked out here or here! But in this post we will look deeper into an…

## SNMP Temperature Monitoring System – Hardware Update

As written about earlier (Do It Yourself: SNMP Temperature Monitoring System) we use the SNMP monitoring nodes in several use cases here at Norwegian Creations. However the blog post does only a minimal hardware setup with a temporary connection method…

## 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. Breadboards come in many shapes and sizes What? A breadboard is a simple tool…

## 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…
