eevBLAB 89 - Youtube is DEAD - Dislike Count REMOVED!
Youtube just announced they are removing the public Thumbs Down count site wide, and only allowing Thumbs Up counts, to "protect" the creators of course. https://www.youtube.com/watch?v=kxOuG8jMIgI They then proceeded to get OWNED in the comments! LOL It's now a free rein for scams, dodgy videos, corporate shill accounts, and the woke elite.
Dave takes a quick look at the Rohde & Schwarz HMO1002 Oscilloscope at their booth at the Electronex show.
A small, light, fanless, entry level 50MHz mixed signal oscilloscope.
