I am interesting to electronics since I was a elementary student.
When I was junior highschool student,I read the principle of television by encyclopedia at my father room then I tried to constrict mechanical television but I couldn't make it because I couldn't understand electric circuit.
I make only NipkowDisk.
When I was high school student,I make mechanical television again.It works successfully,but picture is consist of black or white,no darkness.
After graduation of a university,I work at a electric company,but I quitted it ,and change my job. Now I have much spear time I restart to make mechanical television.
