Have you ever wanted to create a project that involved non-contact detection, such as detecting the closing of a door, counting the number of revolutions of a wheel, or creating a speedometer? Then this blog about the Hall effect sensor is for you. This project uses a Hall effect sensor to detect the presence of …
After making a lot of ESP8266 HomeKit samples, it might be time to explain how to add more than one accessory to HomeKit. Take the ESP8285 – Power Plug for example. Suppose I want to add more than one power plug, how do you do that? I will explain hot to do multiple HomeKit Accessory …
As you know I made some PDB’s in the past for some projects. From “Normal” components I switched over to SMD. But now I want to make things as small as possible. So I was thinking about a project I did a time ago, with a Raspberry Pi Zero W. This raspberry has so called …
In my previous blog here I tested the ESP HomeKit Software Development Kit. I am so enthusiastic about this Software Development Kit, that I going to write a few blogs about this genius software. In each Blog I will address a other accessory that you can add to your HomeKit without the need of a …
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 …
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 is of course a shame. …
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 mechanism and a 250mW laser. …
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 are tools, and so the …
