There are so many cool and interesting things here. Tell me something else from this is available? I have just started to be interested in electronics and so it is important for me to have a few examples of boards, because I am interested in not quite finished products and I am interested in the question of how to build a circuit board at home and preferably with improvised materials, because now it is difficult to find parts and necessary tools in the mute quarantine. Fortunately, I was able to find such a place, so I can't really complain
