    Dude, make subtitles in English. You will have greater reach. You can generate subtitles in English, but they are inconsistent. I learn more from what I observe than I understand from the generated subtitles. I'm Polish and I like watching you. I would like it better if there were subtitles in English. THX

    Why to measure 1v ,1.5,1.8v using DSO? We can use multimeter to measure those voltage . People will not understand because you are not showing full panel of DSO . Need to improve presentation skill if you want to attract customer
