Trondheim Maker Faire 2017
This year’s Trondheim Maker Faire was held last weekend at Solsiden in downtown Trondheim, just like last year. In this blog post we’ll show off a few images from the event. We saw this vehicle made by SK…
Parametric Modelling in Fusion 360 – Making a Triangle Box
1 Comment
Last year we wrote a blog post where we showed how to use parametric modelling to make a simple box. Someone commented that they would like to know how to make a triangle box as well. We thought it would…
Sculptris: First Impressions and 3D Printing
Sculptris is a sculpting 3D modelling software developed by Pixelogic who also have developed the more famous ZBrush. Unlike ZBrush however, Sculptris is completely free! We haven’t looked at Sculptris before, so let’s give you our first impressions before going…
What Is FFT and How Can You Implement It on an Arduino?
In this blog post we’ll first briefly discuss Fourier Transform and FFT. Then we’ll show you one way to implement FFT on an Arduino. Fast Fourier Transform (aka. FFT) is an algorithm that computes Discrete Fourier Transform (DFT). We’re not…
Making a Homemade Travel Ukulele
For an upcoming boat trip, one of our makers was challenged to bring a home made instrument. After some doodling and googling of what to make, we discovered this great travel ukulele design by Daniel Hulbert at circuitsandstrings.wordpress.com. It was clear that we had…
MQTT – What Is It? And How Can You Use It?
In this post are we going to talk a bit about MQTT and give you a quick example of how you can publish a simple message to a MQTT-Broker from a simple computer system (here: an Orange Pi Zero). MQTT…
Repairing a NAD C370 Amplifier – The Slow Start Protection Module Problem
A very common problem with NAD amplifiers (here: C370) is that it becomes very slow to start after some years (10+). The time between power-on and deactivation of the protection increases to several minutes! And why is this happening? In this…
Arduino Tutorial: LCD Displays pt. 1 – HD44780 Character Displays
We have written plenty of Arduino Tutorials, but none of them have been about displays. So we decided to do something about that. This is the first of a planned three-part tutorial series on how to use various displays with…
Building a Quick & Dirty Foam Cutter
Foam is a great and cheap material for various creations. This time we needed to cut some EVA foam into shapes for a prototype we are creating. We were not 100% sure that a hot-wire foam cutter would be the…
Building a Large Kossel Delta Printer – pt. 5: A Video from the Building
We have through several posts now followed the making of a rather large Kossel Delta 3D-printer: Pt. 1: Parts and Planning Pt. 2: Building Update Pt. 3: Electronics and Wiring Pt. 4: Modifying the Effector Here is a a “Making of”-video…
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…
Building a Large Kossel Delta Printer – pt. 4: Modifying the Effector
Let’s take a closer look at the custom modification we’ve done to our Kossel build’s effector. But first, you might be interested in the previous editions in this blog series: Pt. 1: Parts and Planning Pt. 2: Building Update Pt.…
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…
Building a Large Kossel Delta Printer – pt. 3: Electronics and Wiring
It’s been a long wait, but finally all of the parts for our printer have arrived. As shown in this series’ last blog post, we’ve already kickstarted mounting the frame and most of the mechanical parts. The next assembly job…
