The Art of Crimping! Here I show you step by step how to make your own jumper cables for Arduino, ESP32 and Co. – with a suitable crimping tool and some stranded wire you already have the most important materials.

Today I will show you all the different ways you can power up your Arduino, ESP32 or ESP8266 – which ports and pins can be used and what to take care of. Then I will show you two power supply setups if you need a little bit more amperes.

This guide gives you ALL the basics you ever need to start tinkering with 5 Volt LED Stripes like Neopixel, WS2812B & Co. and you beloved microcontroller like Arduino, ESP32 or ESP8266.

SPRYGGKLOPPA is a DIY digital quote frame. It has Wi-Fi so you can edit the quotes, and an extremely high WAF value. It also makes a great gift! I’ll show you what you can do with it and how I built it.

Which batteries and rechargeables are best for powering ESPs and similar microcontrollers? That’s what this article is about. I’ll also show you one of the best ways to mount batteries in your project case.

I’ll show you a clever way to mount your PCBs without screws and still snap them in and out in no time.

I’ll show you a free and powerful alternative for uploading code to your Arduino, ESP or other microcontroller: Visual Studio Code and the PlatformIO extension.

The Arduino can’t do anything and it’s way too expensive! I’ll tell you what my favorite alternative is and why we still love the Arduino anyway. Plus: how to upload a program to an Arduino UNO and an ESP32 in the Arduino IDE.
