Wireless transmission is getting more and more popular. I will try to show you how does it work using coupled receiver and transmitter which are both working on the same frequency (433MHz).
There are many operating systems: Linux, Windows, iOS,… But there are a few which can work in real time like Linux Xenomai. However, there are very little which can fit a microcontroller. One of them is a FreeRTOS. There are some variations of the FreeRTOS which can handle different conditions and requirements.
This blog post is not about such operating system, however…
It was quite a long time since I have written something about my QuadroCopter. Well the time has come. I have prepared a shot movie to which I invite you to watch.

The purpose of this article is to introduce you to one of the methods of making PCB which is the toner transfer method.
A model servo or servomechanism isn’t anything more than just a small DC motor with a transmission and some electronics.
I have done a few project based on AVR microcontrollers. Recently, I have given myself a chance to try out Arduino. After my home thermometer broke down I decided to make a new one. Also it had a few drawback which required fixing. After some time I decided to use Arduino and design a shield for it which would enable this board to measure the temperature and display it. So here it is:
