How to use Websockets to control an ESP8266 and a Raspberry Pi with a web browser

For a current project of mine, I had to evaluate how high the latency is when using websockets. In my case, I wanted to use a small single board computer as the server and any device, that can run a web browser, as the client. This tutorial illustrates how a Raspberry Pi and an ESP8266 can be used to act as a websocket server that can be controlled with a standard webbrowser.

A comprehensive collection of 3D printing tricks – Part 1

I was really busy working on several other projects and many of them involved manufacturing a custom case. The method, I often choose for quick prototyping, is 3D printing and I have found that a lot of people seem to struggle with this technique and so I thought I would collect a few methods that worked well for me and others that didn’t.

Serial to parallel and parallel to serial conversion with shift registers

Shift registers can be used in a wide variety of applications. You can, for example, use them to convert multiple parallel data lines to a single serial line and vice-versa. This technique can be used to extend the number of available in- and outputs of a microcontroller and this article will show you how you can achieve this.
