This brings back fond memories to my first semester studying electronics. First practical, we got to draw a PCB and transferred the image to a copper plate with UV light. Then we dumped it in a solution to eat away the unfixated copper. Second practical, we drilled holes and mounted sockets for ICs. Third, we soldered all components. By then we had all realized that we were building a PIC Micro programmer, which we would be using for the remainder of the semester to flash microcontrollers. This was such a fun way to learn.
