How to use the ESP8266 for wireless communication

More than often enough parts of projects will have to communicate with each other or external devices. This can either be done by directly connecting the devices with cables but sometimes it’s more convenient to wirelessly connect the different pieces of hardware. This article will show you how to use the ESP8266 and it also includes two examples for using it with a Raspberry Pi and Arduino boards.

How to use an EEPROM to permanently store data with your Arduino

Some Arduino boards have a built-in EEPROM that can be written to and read from in your programs. I not only want to discuss how that’s possible but I also want to show you an alternative while talking about EEPROMs and memory in general.

Low latency and high FPS camera stream with a Raspberry Pi

I just saw that two very good sources, that both had an article about this topic, have gone offline without an archived version. And because I continued my work on a robot that is controlled by a Raspberry Pi, I had to figure out how to create a low latency and high FPS stream from the Pi’s camera that can be viewed in a web browser again.

Introduction to Tinkercad and 3D printing

When you build custom projects you eventually get to a point where you want to design a custom case for your product. If you are not interested in learning complicated and expensive CAD software, Tinkercad is the way to go. It’s super easy to learn and to use and it has all the basic features needed for designing custom enclosures for your electronic projects.

C sockets – A hello world introduction

While sockets are no new concept for me, I recently had to write an application in C that uses sockets to communicate. And while trying to figure out, what the best way of doing so is, I came across a lot of tutorials. But most of them either completely missed the point, were too complicated or used obsolete functions in the code. In this article, I want to try to give you a simple and short overview of sockets and an up to date ‘hello world’ example for a client and a server application.

PCB production/etching tutorial

Introduction

There are a lot of tutorials around that show you, how to etch your own PCBs, but either they use professional tools, that might cost a lot, or they do not give you a complete list of materials you will need. This really bothers me, so I want to show you how to produce your own PCBs at home, so you can make your DIY projects more professional and cut costs drastically when it comes to create a PCB.
