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 …
MQ135 sensor is a SNO2 with a lower conductivity of clean air. The MQ series of gas sensors uses a small heater inside with an electrochemical sensor. These sensors are sensitive to a range of gases used at room temperature. When the target explosive gas exists, the conductivity of the sensor increases more and the …
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 € …
If you want to control a Stepper you can do this using a micro-controller, this will take up a lot of the processing resources and not leave you a lot of room to do anything else. If you need to control a bunch of stepper motors, this will be a greater problem, unless you use …
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 …
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. …
The 28BYJ-48 is one of the cheapest stepper motors you can find. Although it is not super accurate but yet powerful, it is a great motor to use for smaller projects or if you just want to learn about stepper motors. The 28BYJ-48 is often used to automatically adjust the vanes of an air conditioner unit. …
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 …
