Datalogging with a Multimeter
1 Comment
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…
Customizing a Retractable Power Strip
For our new office we bought a couple of used tables with inset retractable power strips (an old version of the Evoline Port). One of these had a VGA socket in addition to all the power sockets. Instead of the…
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…
Behind the scenes: “Blåfrost 2016”
This is a behind the scenes post from something quite technically manageable, and at the same time visually very powerful! The case is an interactive installation that turns on the lights and starts up the internal smoke machine whenever…
The DIY 3D Printer Life – Part 1: Cooling
About a year ago we bought a Prusa i3 printer from Geeetech. At the time, it was probably the cheapest printer on the DIY market at 249$. As expected, the printer had several areas which needed improvement. In this blog…
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…
Hacking an Old VHS Player
As a part of a new project, we wanted to use an old VHS player as a trigger for various actions. We wanted the system to trigger when a VHS cassette was pushed into the player, as if one wanted…
Using EEPROM to Store Data on the Arduino
When collecting or generating data and storing it on a microcontroller, like the one on an Arduino, the data will just be available while the microcontroller is powered. As soon as you pull the plug and the microcontroller loses power,…
Building a Large Kossel Delta Printer – pt. 2: Building Update
Four weeks ago we wrote about a 3D printer we’re building. Now we have started building it, and we thought it’d be cool to share some of it in this post. Various Discussions and Pictures of Stuff This image doesn’t…
Getting Started with Programming – Part 7: Pointers in C
It’s been a while since the previous part of this series. This edition will take a side-step away from the regular Arduino/C++ and Python examples and look at the language C, which is quite similar to the Arduino/C++ language. This…
Electronics 101 pt. 3: Applying the Laws
Earlier we have written blog posts about both Ohm’s Law and Kirchhoff’s Laws. It’s time to put these in action combined to analyze simple DC circuits. Sounds fun, right!? Don’t worry, it’s pretty easy and straight forward, and we’ll walk…
Building a Large Kossel Delta Printer – pt. 1: Parts and Planning
Access to a 3D printer is very important for us in Norwegian Creations. Now we’ve decided that we want to upgrade our 3D printer park with a new big and fast printer. This time we’re going all out with a…
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…
