boopable CRT.
but why does the boop affect the electron beam?
@grishka bit of a charged subject
@tubetime
What is the origin of "boop" ie. touching someone's nose and going "boop" ??
@tubetime Why does that CRT have an electrode in the centre? I've never seen one like that.
@philpem radial deflection. used for J-scope radar
@tubetime @philpem Types like the soviet 8LO30I
You run the XY plates to display a circle, and the inner pin (versus an ring that is not visible) for radial deflection, like pointers on a clock
@tubetime noooo, my boop deflector!
but why does the boop affect the electron beam?
