This channel is underestimated, i expect it to hit 1 million sub. soon.

I just got through the first third of the video, about to watch the rest. After watching between half dozen or a dozen 555 vid, Im finally beginning to get it with this video here! Thanks !!!
I cant believe only 6k views in 1 year, thats nuts. I wonder if you might consider splitting your channel into two channels. Having only glanced at your videos, I imagine your exposure in the YT algo might be diminished by what they (they, not me) consider unfavorable. Just a suggestion. I wish you the best, cant wait to finish watching this vid and more of your vid. Best luck with the channel and please keep posting electronic vids!!!

Wow such an excellent, in-depth explanation! The visuals were really well dotne and very helpful. This was the first one of your videos I’ve seen, and i look forward to watching many more. Thanks for taking the time to create them! 😊

Thanks, your videos are really great. Hope u get more people to acknowledge you.

Thanks for giving me an excuse to drift away for half an hour :)

Best device vids ever!

[@daveb7999]

Great video, thanks! Some of this information is over my head, but you explain everything very well. I subscribed to learn more.

Thank you 👍👍👍

Dear Ron Mattino, can I get your opinion on the video about the 555 timer that I published on my CZcams channel?

[@macgyver5108]

The main reason you can't rely on NE555 timers... They always _flip-flop!_ 🙃
