I remember when I first saw Steadicam stabilized recording and I was completely amazed by the soft camera movements. It looked so good like it was flying. Of couse it was only a mechanical filter. Since then everyone has gimbals because of the phones and action cameras. They all use active stabilization.I also bought an
I was interested in the smart home topic for a while and finally the first actuator is operation in my flat. I’ve already had sensors and I processed the data coming from them using a Raspberry PI and RRDTool which was spectacular. During a heat wave in the summer the need arose for controlling the

The fun We converted back one of the RobonAUT cars to a regular RC car. It had a decent speed by default but we managed to make things more interesting by replacing the motor and the motor controller. We chose a brushless motor and a suitable controller. We configured the controller with it’s programmer module

Our team’s name was “Runner-up” and we finished as the runner-up on the first two occasion and we shouldn’t talk about the third one. 2015 We started the development with huge delay because of our study tasks but we always managed to
After many MCU based project I had a need to have a generic protocol between a PC and an MCU. Protocol My protocol communicates in a binary way not a text based way so it provides kind of a dense communication. This make it able to transmit high resolution real-time sensor data. The values are

One my friends from middle school had the idea to create a cheap device that can measure and collect the LTE signal levels.We got a suitable devboard for the prototype and I ported OpenWRT to it. I also needed to modify the LTE module’s driver to make it work.The user-space software sent the data to
