Hi, I'm Akos Pasztor!

I am a Hardware & Software Engineer, targeting Embedded Systems.

I design hardware, including analog, digital and mixed-signal circuits and printed circuit boards. I develop embedded software and firmware, mainly for microcontroller-based systems. I live in Switzerland and I hold a master's degree from ETH Zürich.

This is my website about my projects.

Scroll down for news & updates.

Simple LAMP Stack with Docker Compose

In an embedded development environment, containerization and containers are still somewhat unfamiliar and not (yet) widely adopted, especially when it comes to smaller projects, or when you are not dealing with DevOps and CI/CD. Fortunately, this trend seems to be slowly (but surely) changing.

Docker uses OS-level virtualization to deliver applications and software in so-called containers. At first glance, this might seem less useful for firmware engineers writing small bare-metal code for microcontrollers - or hardware engineers designing schematics and PCBs. However, it is an extremely powerful and versatile tool and I strongly encourage you to read about it and use it - it's free and open source!

Since I've learned about containers in details, I've started using Docker for my side-projects as well. For instance, I stopped using XAMPP to develop my website (and other sites). Instead, I created a lightweight LAMP (Linux, Apache, MySQL, PHP/Perl/Python) stack using Docker. This allows me to quickly fire up the containers in a matter of seconds whenever I want to work on my website, regardless of operating system, environment or whether I'm using my desktop PC at home or my MacBook on the road.

Projects and Website Update

It's been a while since I have posted something new on my website (I know, I know...). So with this post I would like to give a quick update about what happened recently and what is currently in the pipeline regarding my projects.

A lot has changed since my last post. I left Sensirion in 2022 to pursue new opportunities at Landis+Gyr. It was an amazing 3.5 years at Sensirion. I broadened my skills in both software and hardware engineering. I'm very grateful and at the same time proud to have engineered some of the new generation of sensor modules ranging from consumer to automotive sectors, which sell over 1M+ units per year. As I'm always keen to learn new stuff, I took a deep dive into the field of infrastructure: I learned a lot about CI/CD, build systems, virtualization and automation. I also got to know some fantastic and highly-skilled people at Sensirion, from whom I have learned a lot, not only professionally but also on a personal level.

I joined Landis+Gyr in the summer of 2022 as a Senior Firmware Engineer. Landis+Gyr is the market leader in electricity meters. I'm currently working on the firmware for the new smart meters. A few weeks ago I received a flyer from the electricity supplier company where I live. They are going to install the new smart electricity meters from Landis+Gyr in my area! That was the moment when I realizd that this is exactly why I'm in this field: it's an amazing feeling to see something I've worked on come to life, be deployed and serve the people.

As I'm currently working full-time, it's difficult to devote time to my projects. I actually have quite a few ideas in the pipeline, some of which I have already implemented. Some of them have already have an MVP (Minimum Viable Product), but I still have to document them properly before putting them online. These projects target some firmware, software and infrastructure-related ideas. I've been also toying with the idea of diving into the latest front-end and back-end technologies - just for fun!

In the meantime, I did some maintenance on my website. I merged the Snippets into the Projects page - so that there is only one streamlined page for all of my projects, added a new Skills section to the About Me page, and updated some outdated information on my website. I also added some new styling to the navigation bar, fixed some formatting issues and made some under-the-hood changes.

So stay tuned, and get ready for some new projects in the coming weeks!

STM32 RTC Scheduler

I've managed to find some time to finalize my latest project and its documentation: the STM32 RTC Scheduler project! This is an RTC-based scheduler implementation that allows applications with real-time operating systems (RTOS) to schedule and execute recurring, periodic tasks while minimizing power consumption to maximize battery lifetime.

The RTC Scheduler is demonstrated on the STM32L496-Discovery board. The example project can be compiled straight out-of-the-box with IAR EWARM, Keil uVision and GCC for Arm toolchains.

1-year anniversary at Sensirion

After finishing my master studies at ETH Zürich, I started working as a Hardware & Firmware Engineer at Sensirion. I'm responsible for designing hardware and developing firmware for the upcoming sensor devices and modules for consumer, industrial, medical and automotive applications, as well as custom, state-of-the-art hardware platforms used internally in R&D, testing and production.

Since I'm employed with 100% workload, this unfortunately means that I have limited amount of time to work on my personal projects. Ironically, I have nowadays more project ideas than in the past years... Nevertheless, I will definitely keep developing new ideas and side-projects, so stay tuned for upcoming updates!

IPSN 2019

The state-of-the-art geophone platform I have developed as my master thesis at ETH Zürich served as the basis hardware of a research paper which got accepted and published in the Proceedings of the 18th ACM/IEEE International Conference on Information Processing in Sensor Networks (IPSN) journal. The event was organized between April 16-18, 2019 in Montreal, Canada.

Successfully graduated from ETH Zürich!

I received my master's degree in Electrical Engineering and Information Technology from ETH Zürich in 2018.

The past years were filled with lots of events and hard work. Beside my studies, I was working part-time for the Computer Engineering Group at ETH Zürich for almost two years, continuously. Then I started my master project, a state-of-the-art geophone platform, which had remarkably great results. The developed system was even featured on SRF Einstein (Swiss TV show).

I would like to thank everyone who supported me during this challenging and exciting journey.

The Geophone Platform is featured on SRF!

I am happy to announce that the geophone platform I designed and engineered as my master thesis at ETH Zürich was featured on SRF Einstein (Swiss TV show). The part of the episode, titled "Forschung extrem: Datensammeln im Permafrost" introduces the geophone platform alongside with the wireless sensor network deployed and operated in the Swiss mountains.

Geophone Platform

I started my master thesis titled "Event-based Geophone Platform with Co-detection" in November 2017 at the Computer Engineering Group of ETH Zürich. My work is about developing a new, state-of-the-art networked sensor platform focusing on detecting and recording micro-seismic activities to provide early warnings for natural hazard mitigation. It features ultra-low power consumption; always-on, dual-side, multi-stage triggering; co-detection and more.

I have already finalized the hardware design, and the software is currently receiving its final touches. The hardware already went into production state, and currently 50 pieces are being manufactured. They are going to be deployed and used this summer in the Swiss mountains. Check it out:

The myPhone v2.0 documentation in Hungarian

Now you can view the documentation of the myPhone v2.0 project in Hungarian!

Read more about the myPhone-v2 project here:


The myPhone v2.0 is finished!

Today I have completely finished the myPhone v2.0 project!

I had to replace some components (eg. resistors) to everything be perfect and I have finished the software too. I'm sure there are a few minor bugs in the code but I have limited time and the device is made in order to learn a lot during the making and not for commercial use. Moreover, I have new ideas how to continue and improve the device and myself. Maybe equip it with new components like LCD touch-screen, bluetooth module, WI-FI module? Then I'm sure I need a new, more powerful processor like an ARM...

Building the myPhone v2.0

I got the PCB-s to manufacture here at the university (BME), at the ETT department. They were fast, so I could start the soldering shortly after I placed my order.
I'm soldering all components by hand. Here are some photos about the progress:

Now I can continue my work on the myPhone v2.0 project. This myPhone will really deserve the name "mobile" phone as it will have two rechargeable batteries for power supply. I will put the PCB in an enclosure with a small loud-speaker and a microphone. I have plans for the keypad too: a custom designed foil keyboard with cutouts on the top of the enclosure!

Site is ready!

I decided to build a website, so you can follow my projects and academic work here. If you have any questions, feel free to contact me. You can find my contact information under the Contact menu.
