Some mechanical components
The aim of this article is to give you a quick overview of the various mechanical components you're likely to come across on robots or 3D printers. This will give you their names, which will help you in your internet searches, as well as their functions. There are a...
Project DeadSpool : recycle empty filament spool
The DeadSpool (or empty spool) project is an initiative aimed at finding solutions for recycling empty 3D filament spools. When you use 3D printing regularly, you usually end up with a stock of empty spool as you consume the filament. Some ideas for Deadspool...
Teensy 3.5 microcontroller overview
The Teensy 3.5 is a development board with a 32-bit ARM processor. It has a large number of interfaces and high computing power, enabling it to be used in a wide range of applications. In particular, it can emulate USB devices, so is often used to develop HID or MIDI...

Control 8 relays using ESP32 and serial monitor
In this tutorial we will see how to address each relay individually with a NodeMCU32S microcontroller and 74HC595 shift registers. At the end of this tutorial you will also be able to control each relay using the serial monitor. This tutorial follows on from the...
Controlling 8 relays with ESP32 and shift register
In this series of tutorials, we will see how to drive a multitude of relays with a NodeMCU32S microcontroller and 74HC595 shift registers. We will then see how to address each relay individually. Finally, we will create a web interface to control each relay via the...
Adding the F() function to an INO file with Python
One of the big interests of programming is to automate simple tasks. A good example I have encountered is the modification of several lines of code in an INO file for Arduino. After writing a few dozen lines of code in C++ for my Arduino project, I found myself with a...
