Maybe you want to make a PCB with SMD components. To do this, you need a so-called reflow oven. Various projects can be found on the internet to make such an oven. But here comes the problem, most projects use a custom PCB based on SMD components. This is the same if you contact the […]
UPDI? Never heard of it? You may be familiar with the ATtiny series of microprocessors from Microchip, such as the ATtiny85 or ATtiny2313. These chips powered small systems like the Digispark series. Unfortunately, they had limited Flash (usually no more than 8K) and even more limited RAM (usually less than 1K). Now a new series
On August the 24th, the Deputy Editor-in-Chief of Make magazine Germany (Peter König) send me a mail. They are in the process of making a special issue about the ESP32-CAM, and they wanted to know if it is okay for me to use my graphical version of the ESP32-CAM, as also seen on my blog

The upload procedure for ESP32 boards is a little different from a standard Arduino procedure. Most Arduino’s will automatically reset when a new program is being uploaded, and will automatically enter programming mode. On some ESP boards you have to manually enter programming mode, and on the bare-bones modules, you even have to reset them

Track width is one of the most critical factors of any printed circuit board (PCB) design. Anyone who has a good knowledge of track design will at some point face the challenge of determining the correct track width. Inexperienced designers tend to use the standard gauge given in the PCB layout software. And this can

I wanted to see if I could make a more realistic (LED) candle that you can buy in all kind of stores or on the internet. My idea was to use NeoPixels because I can control each pixel in every colour I want. But first I googled to see if someone has done it before,

Not all European legislation for the standardization of USB-C for mobile devices, but also the switch of all kinds of electronics to USB-C will ensure that USB-C will become the standard. Look, but since the already well-known boards Arduino, Raspberry Pi, wemos boards, etc. have all already replaced the Micro-mini-USB ports with the USB-C port

The Wemos ESP32-S2 is a small Wi-Fi module based on the ESP32-S2FN4R2. The S2 is a new version of the well-known Wemos D1 Mini. The biggest update to the S2 is about twice as many I/O pins in the same form factor. This means that most shields intended for the Wemos D1 Mini can also
