Sequence programming in C/C++ Part 1:Counter

Introduction A sequence is a series of predefined actions with clear conditions for transitioning between each other and since it is predetermined it also has a beginning and an end. Sometimes a sequence is in a loop that repeats itself and in those cases it can be hard to see where it starts and ends […]

What is a PLC or Programmable Logic Controller?

Introduction PLC:s are a form of industrial control hardware that is very rugged in its construction. PLC:s are used to control everything from small packing machines to complete assembly lines in every imaginable industry. There is a sister category of controllers that are called RTU:s, which stands for Remote Terminal Unit. RTU:s are very similar […]

PID demonstration RIG Part 2: Hardware

If you haven’t read PID Demonstration RIG part 1: Software I highly advise you to do so before continuing, otherwise it might be a bit hard to follow along. When building stuff like this it is really awesome to have a 3D printer If you can come up with an idea and model it in […]

PID demonstration RIG Part 1: Software

Introduction In the PID regulator article I mentioned that I had an upcoming project utilising a PI regulator, this isn’t it, but when I was writing that article I though to myself that there must be a simple way of demonstrating visually how the different parts of a regulator effect the system as a whole. […]

Why HMI:s should be made intuitive

Take a look at the picture above and try to imagine how long it took the astronauts to learn the position and function of every button on there. The picture is of the interior of Apollo 11’s Command Module “Columbia” . Photographer Eric Long, Courtesy of the Smithsonian’s National Air and Space Museum I am […]

How not to build a 3D printer

How not to build a 3D printer I have a 3D printer. It’s a Cartesian printer with a build volume of 300×300x280mm and it is controlled with a RAMPS board on a Arduino Mega running the software Repetier. It’s frame is based on extruded aluminium profile and the rest of the hardware is milled aluminium. […]

Software based PID regulators

Introduction What is a PID regulator? The short answer is that it is an automated control function. The long answer could fill a couple of textbooks. Because of this I won’t delve to deep into the subject but I have an upcoming project that utilises a PI regulator so writing some form of introduction seemed […]

The site is live!

I have finished with both the About me page, and the purpose page. They are both live. Sure they have some over lap but I figure it is better to go ugly early than postpone publishing anything. I can always update them in the future. I probably will at some point but til then, have […]

First visitor!

I just noticed something fun! According to my analytics widget I recently had my first visitor. My bounce rate is currently 100% by the way. I’m guessing that this will change when there is any content at all on the site. I mean so far I only have a short explanation of the page online, […]
