I was notified by youtube, that there was a new potentially interesting video. So I had a look.
It turns out the video shows a small oscilliscope based on an oled display:
The display and controls looked kinda familiar to me. So I asked in the comments whether it was based on the DIY Oled Display on this web page in Japanese that I myself have built and written about here.
The question disappeared from the page within a few minutes.
Entering the question a second time had the same result.
did you include a link? that is strictly forbidden on youtube, I think the channel owner can approve them but they are hidden by default, they won’t even see them on the yt phone app I don’t think
In my town one year the water went brown for about a week because the building contractors dug up a water main. The fountain went higher than the lamp posts.
