Lukasz Skalski

I am an embedded software and hardware engineer.

About Me

TL;DR

Hi, I’m Lukasz Skalski and I live in Gdansk (Poland). I’m open source enthusiast and guy who lives and breathes all things related to IT (especially Linux and embedded systems). While you are here, I hope you can find something interesting. Please feel free to contact me.

Who am I

My name is Lukasz Skalski. I was born in 1988. I spent my whole childhood in a small, but very charming town – Izbica Kujawska. In 2008, I graduated from the Complex of Electronic Schools in Wloclawek. Then I started studying at Gdansk University of Technology – Faculty of Electronics, Telecommunications and Informatics (major: Computer Electronic Systems). In 2012, I was awarded a title of Electronics Engineer. My thesis was Bioimpedance Measurements. The two publications below are the results of my work (I am one of the authors of these texts):

“Monitoring of a bathing person” (published in Journal of Medical Imaging and Health Informatics)
“Detection of person presence and its activity in the bathtub” (XV International Conference on Electrical Bio-Impedance – ICEBI)

Furthermore in 2012, I published my first book about Linux for embedded systems – “Linux. Podstawy i aplikacje dla systemów embedded” as a result of my cooperation with Wydawnictwo BTC. The book is a guide on hardware (GPIO, I2C, 1-Wire, RS232, etc.) and software (Linux kernel, u-boot bootloader) aspects of using Linux on ARM architecture.

In 2013, I gained a Master’s Degree. You can find more info about my Master’s Degree Thesis here – Virtual Impedance Meter. Since graduation I’ve worked as a (Junior, Mid and Senior) Software Engineer at Samsung Electronics (Samsung R&D Institute Poland). In 2017, I started my own business – Skalski Embedded Technologies – to pursue the work and projects I love.

What about my hobby? I’m interested in everything, but I don’t have too much time to fulfill all my plans, projects, etc. I spend all my free time on designing various devices with small microcontrollers and creating software. My particular interest is Linux for embedded systems, open-source software and hardware-software interfaces. You can find some of my hobby projects in this blog. Character traits? Stubborn and tenacious in achieving my goals.

This is only a brief summary of myself. If you are interested in getting to know me better (my publications, work experience, awards, etc.) please visit my Resume page. Please feel free to contact me.

EDUCATION

2008 – 2013

Computer Electronic Systems – Master’s degree

Gdansk University of Technology

Master’s Thesis – Virtual Impedance Meter.

The designed device is compact and easy to use Virtual Impedance Meter allowing to measure impedance in a wide frequency range (from 10 Hz up to 100 kHz). The most important features of the analyzer are small size (4-layer PCB) and low production cost. Thanks to the use of an impedance measurement method based on DSP and AD5933 microsystem (high precision impedance converter system solution that combines an on-board frequency generator with a 12-bit, 1 MSPS, analog-to-digital converter) with complex analog conditioning circuit, the developed instrumentation can be compared to portable analyzers offered by top worldwide manufacturers.

Controlling the Raspberry Pi via the WebSocket protocol

Tanzstunde: Raspberry Pi steuern mit Android

Raspberry Pi Geek – Linux New Media USA, LLC

Linux Magazine – COMPUTEC MEDIA GmbH

Abstract: The various small computers with relatively powerful microprocessors now on the market are attractive to developers, engineers, and makers alike. The processors provide fast and easy access to hardware buses via I2C, 1-Wire, or SPI, allowing users to combine the worlds of software and electronics. Connecting data to the real world – for example, by reading external sensors or controlling actuators – calls for simple and efficient communication between a client and server, as provided by the WebSocket protocol. Basically, this technology is used when you want to realize fast and powerful, bi-directional communication in real time between web applications and clients. In this article, I present two sample projects involving the operation of a Raspberry Pi as a WebSocket server to which a WebSocket client sends asynchronous broadcast messages […]

Jesien Linuksowa / Linux Autumn / 2014 Conference

At the beginning of November 2014, I had the opportunity to give a speech at a “Jesien Linuksowa 2014” conference. “Jesien Linuksowa” (Linux Autumn) is a “[…] social-scientific meeting for enthusiasts of the Free Software and the GNU/Linux that is organized by the management board of the Polish Linux Users Group”. It was also the first opportunity to present new (pre-release) version of my application – “Raspberry Control 2.0“.

Monitoring of a bathing person

Journal of Medical Imaging and Health Informatics

Abstract: Ageing of the population in developed countries is a major problem and a challenge not only from a social or an economic point of view, but it is also a challenge for engineers, as in the near future there maybe a lack of personnel to take care of the elderly. […] We analyze possibility of bathing person presence by means of impedance spectroscopy. We study optimal electrode configuration for detection of the person in the bathtub and influence of bathing water ingredients (salts, shampoo, soap) on the detectability. Finally we are interested in estimation of person’s activity during the bath process by means of impedance measurements. We have designed prototype of such embedded system and showing results of primary measurements […]

Detection of person presence and its activity in the bathtub

XV International Conference on Electrical Bio-Impedance (ICEBI)

XIV Conference on Electrical Impedance Tomography 2013 (EIT)

Abstract: A practical application of a bioimpedance technique for a detection of a bathing person is presented in the paper. It addresses the possibility of supervising people in the bathtub without voiding of their intimacy. The measurement system installed in a fiber-glass or a plastic bathtub is able to detect a presence of the bathing person, to estimate its activity and thus to detect potentially dangerous events. In the paper a principle of measurement, working prototype and measurements are presented. The proposed method can be useful for supporting and supervising bathing of elders, partially disabled or people with some health state risk during the bath and living alone.
