Przemysław Krawczyk

the owner

Lotharek is a family company with entirely Polish capital which has been in business for 20 years. My name is Przemysław Krawczyk and I am its founder.

I owe everything I do professionally to the passion that was born in me when I was 15 years old and I swapped my first Atari 65XE computer for a Unipolbrit 2086. I still remember that feeling of excitement, the emerging passion and the realization that I already knew what I wanted to do in my life. From that moment on, looking for new technical solutions, expanding devices and implementing new electronic projects has been a challenge to which I have devoted my life completely. By making more attempts and assembling everything by hand, I slowly learned to improve the devices I liked.

I have worked with many excellent designers and electronics engineers. What came out of their hands was a blueprint, a prototype. My job was to turn the design into a product: designing the board, taking care of ergonomics, miniaturization, finding suppliers, ordering and supervising production and sales. Today I am proud of my devices such as: Ultimate, DivIDE, SIDE3, Rapidus, Hydra, etc.

I consider it my great success that the Boeing Company uses my floppy disk station emulators in its flight simulators, and the US Federal Aviation Administration has equipped more than 300 civilian airports with my equipment.

Every failure, every found mistake, taught me patience, but also allowed me to develop furthermore. An independent production line, which I launched in September 2021, is the result of that journey. Since then, I have been an independent producer: from the idea to the finished solution. And I still love what I do.

Apart from electronics, judo is my second passion. It is on the tatami where many ideas or solutions to technical problems are born. Effort, a fresh perspective, consistency and decisive action also come in handy in the professional life. Knowing that you never know everything, taking a step back, looking at things from a distance in order to win in the end, these are principles I have learned in training. I know how important it is to be trusted by the customer. I try not to let them down at every stage of our cooperation.

I also do charity work. I financially support retro events (Lost Party, Wapniak, Last Party), I help children from the Special Needs School in Piekary Śląskie, I help to promote a healthy lifestyle and my passion for judo. I believe that life has given me so much that I should share. Thank you for visiting my page and I invite you to cooperate with me!
