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

After a vacancy I got a ticket to the Hackaday Superconference to Belgrade so we travelled to the Balkans with my collegue. Travelling Buying a train ticket caused us difficulties because we could not do it only. We also check the Serbian train company’s website. At least we found that we can buy tickets at

We signed up for the NNG programming competition this year too. As usual the first round is held online where we finished as the runner-up. In the finals we had to create a bot for the specified game and fight with the other teams. The game Round based game Square shaped, tile based map Simple

Two of my colleagues contacted my to join their team on the NNG’s programming competition and I was of course willing to do this. Our goal was to finish as the runner-up and win the Herman Miller chair so our team name was Hárman Hermané (it a pun, it means three for Herman). The final

We participated in the three consecutive years in the BUTE organized RobonAUT contest. 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

As a result of a homework for the specialization I made a USB thermometer that can read the data of OneWire sensors. The base of the device is an STM32F4 Discovery kit that has a 168MHz Cortex-M4 MCU. My circuit is connected to the kit by the expansion pins. There’s three 7 segment display, two
Az önálló laboratórium tárgy keretében készítettem egy GPS adatgyűjtőt, amely MicroSD kártyára tudja menteni a bejárt útvonalat. Ezen kívül a kijelzőjén képes megjeleníteni különböző adatokat, mint például az aktuális pozíció, sebesség, irány, stb. A tárgy befejezése után még sokat foglalkoztam vele, így plusz funkciók is beépítésre kerültek. Felépítése Az áramkör központi eleme egy PIC32MX mikrokontroller,
