The Beginner Programmer

Linear programming is a technique to solve optimization problems whose constraints and outcome are represented by linear relationships. Simp...

This post is a follow up of this project. After a lot of fiddling around, I finally built up the circuit for automating the turn on and off...

This is a short post following the previous one ( PCA revisited ). In this post I’m going to apply PCA to a toy problem: the classification ...

Principal component analysis (PCA) is a dimensionality reduction technique which might come handy when building a predictive model or in the...

This week I finally got to play around a little with some electronic components I ordered and test them before using them on side projects. ...

When you learn about the Fourier transform and what it can show you about a signal, you immediately start thinking about its possible appli...

One of the perks of knowing a programming language is that you can build your own tools and applications. Depending on what you need, it may...

Recently I’ve been getting familiar with AutoCAD and at the same time I’m trying to improve my Python skills. Odd mix, huh?! While trying to...

Recently I had a brilliant idea :D why not make a rotating magnetic field that can rotate a needle of a compass? (or any other magnetic need...

Finding analytical solutions to physical problems is always nice and rewarding, however it can be a bit of a pain when the geometry of the p...

FEMM stands for Finite Element Method Magnetics, and it is a nice software for solving magnetics and electrostatics problems. I’ve known FEM...

Balancing a ball on a beam is not a common problem you may face during your everyday life, however, this simple example of engineering can b...

Electrically speaking, a permanent magnet DC motor can be modelled as follows: applying LKT we obtain the following differential equation $$...

More than 2 years ago I wrote a short post on Taylor series. The post featured a simple script that took a single variable function (a sine...

Some time ago I wrote a short article on a small circuit I made to power on and off my garden lights using only a handful of components and...
