How big of a number is 64bit? Quite big as it turns out:

Let’s see why floats are traditionally avoided in embedded systems. In reverse in a system that does use them, removing them is a very good opportunity to save space when needed.

Let’s do the experiment of doing calculations bigger than the bus size of a modern microcontroller and see how bad the generated assembly code look.

We have a look at what goes into making a webpage able to call a python script. As it turns out the security requirements makes it so that it requires quite a few layers of script:

Let’s see how to have multiple tasks inside of our micro controller without having to install an OS in it.

Does doubling the number of bits of a microcontroller double its processing power? What does it mean this number of bits?

In 100% of the embedded projects I worked on, memory became an issue at some point. Either not enough RAM or not enough flash. Here we see an easy way to optimize our data structures in order to save space in memory at no cost of performance!

Finding out what is inside of a battery charger and investigating why one of them never seems to finish charging:

How slow humans look as seen by a microcontroller. In this video, we test how much time a human takes to react to an input coming from a microcontroller.

This time we have a look at how to leverage the true random we generated using a Mersenne Twister to generate a lot more random numbers.
