A few weeks ago I was looking for a small oscilloscope module. While searching the web I came across the type DSO138 from the company JYE Tech. The bandwidth of 200 kHz and the maximum sample frequency of 1 MHz were sufficient for my application. Because these modules are so …
For those who follow my blog know that I have a 3D printer. Besides thinking up and creating everyday solutions with my 3D printer, I also like to draw 3D models. In this case the 28BYJ-48 Stepper Motor. By drawing 3D models I learn “playfully” more and more. I sometimes …
The upload procedure for ESP8266 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 …
For those who follow my blog know that I have a 3D printer. they also know I am thinking up and creating everyday solutions with my 3D printer. By drawing 3D models I learn “playfully” more and more. I sometimes made models in the past, which I later removed again, this …
This is one of my bucket list the CNC – Mini Laser Engraver. You probably have seen one come by at one point. This is an blog on how I made an Arduino CNC – Mini Laser Engraver for wood and Thin paper, Just using some old DVD drive stepper …
For anyone out there who has ever struggled finding a part for KiCAD, there are some who would say you’re doing it wrong. You’re supposed to make your own parts if you can’t find them in the libraries you already have. This is really the only way; PCB design tools …

Slowly but surely I am looking at the extensions of the “standard” ESP HomeKit accessories, how to implement them. Now I am working on the Battery status. We need some circuit which can effectively measure voltage. Battery monitoring circuit is a traditional voltage divider circuit. I am going to measure …
