I am Bartek, known as "Kasztelan", a technology enthusiast from Poland. For 2 years, I have been involved in 3D printing, electronics, and DIY device design. I specialize in creating button boxes – control panels for simulators and automation, utilizing Arduino, Raspberry Pi Pico, and DC motor control. 3D printing and CNC technology are my main tools. My greatest achievements are my original button boxes, which combine functionality with design. In the future, I want to continue developing, creating more advanced control systems and experimenting with new technologies. DIY is my passion
