About me

   My name is Karol (it's Charles in English, just like Charlie the unicorn :P). I'm using c4r0 nickname in the Internet community. I was born in 1987 in Poland and I went to Gdansk University of Technology to study Optoelectronics. I've been interested in electronics for veeery long time. A proof is the left of the following pictures where while being a pretty young guy I'm already holding some PCB removed from an old TV :) The picture on the right shows more how I look these days (2013).

   My main interests after electronics and science are various sports, mostly those called extreme sports. For the last 10 years (with several breaks) I've been an amateur acrobat and gymnast on self-taught basis. Besides that I'm an active snowboarder, mountain biker, I do rock climbing and recently I'm getting into alpinism. Until around 2011 I was spending most of my free time in my workshop working on the DIY projects presented on this website. In 2011 I went for one year internship to Veeco Instruments where I worked as an electrical engineer designing a module for new generation lapping system dedicated for HDD magnetic heads manufacture process (I later based my Master's thesis on this). Since then I had to leave my home workshop behind, and moreover, I started spending my days working on electronics and programming as a job, so I stopped working on the DIY projects. This is the reason why since 2011 this website is almost dead. After graduating with Master's degree I went for another internship, this time at Bruker, where I worked on a prototype of Tip-Enhanced Raman Microscope. Currently, since mid 2013, I'm a PhD student at ETH Zurich building an atomic force microscope operating at liquid helium temperature and trying to use it to characterize and improve superconducting single-photon detectors. I've been trying to write something about this project here on this website for a very long time but it's going very very slowly... Below you can see two more pics of me. In the left one I'm doing something to the cryogenic scan head I'm building, and on the right it is a picture from a trip to Tatra mountains in 2015.

   And here you can see a short video of my acrobatic tricks from the years of 2007-2009 :)
