it amazes me that at some point people had to invent these things

[NotMassLucks]

14:45 I am still amazed at how coordinated you are doing three separate things at once: moving the pen at a constant speed and pressing two different buttons at different times in different combinations.

Having watched 5 videos previous to this, from transistor logic gates to the D latch, the use of the inverter delay in the edge detection circuit blew my mind to pieces. Biggest crossover event in cinematic history

[DJayDiamond]

After 3 months of nonsense lectures at uni it take me about 20 minutes of watching your videos on latches and flip flops to completely understand it! Thank you so much for making these :D

Using propagation delay of gates to build an edge detection circuit always reminds me of the quote, "when life gives u lemon, make lemonade out of it"

[カラスKarasu]

You are every nerd's dream teacher

[pnesap]

man that breadboard time machine is crazy!

[danielpeck]

I swear you explain clearer than 99.99% of prof in the university.

[aidanstanford]

It feels like I learn more from these videos than from school, imagine that!

[okiedokie]

Amazing how you explain all these things step by step! I wish you were my teacher years ago. If they explained electronics the way like you do then my country would probably be on Mars already.

[NineInchFailz]

the edge detector is so clever. Never would have thought to exploit the delay in an inverter to create a quick pulse.

[yerriswamyk.m]

You are wonderful teacher, keep posting videos and make us educate, can you make a video on pull up and pull down resistors.

[silverbladeii]

what amazes me is that Redstone is so similar to all this. The first flip flop I learned in bedrock edition is a d flip-flop

[burhanuddin]

This guy is so so so so so underrated.... I challenge no one is explaining this kinda topics currently on the you tube.

[antonnym]

Very nice explanation of the flip-flop! I enjoyed learning about the delay which causes the true condition on the AND gate output. Very cool!

[ucantSQ]

Does anybody else feel the excitement building as the pieces come together?

[canofsoda]

I just got an electronic kit and ive been binging these videos. Ben Eater is definitely to 50 people ever. like everyone else who's commented on his videos has said, everything just makes sense. he doesn't tend to explain things that don't need to be explained, and the things that do need to be explained are explained at the right speed, at the right time. i wish i could be in his class

[francoisguyot]

You'rte a great teacher, Ben. I love the way you evolve from the SR to the D flip-flop by incrementally adding complexity to the circuit showing the evolution of design techniques.

[WhitEagle]

dude I kid you not I left computer engineering in favor of physics because my instructor couldn't explain this well enough! in 3 videos that took me about 30 minutes to watch I got it all!

This is SUPER helpful. I'm taking a computer architecture class online and didn't understand the book. This cleared it up for me.
