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 very cheap for barely € […]

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 made models in the past,

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 even have to reset them

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 3.7 volt (lithium Polymer) battery.
