Soon he’s going to hook up the video card and make a text editor with it

[PixelSchnitzel]

I'm sitting here yelling "no, use a 7414 instead of a 7404" and then I remember Ben's teaching style. Then I sit back and watch for the object lesson. OMG, I wish I had a teacher like Ben many years ago. These videos stand out as some of the finest teaching I've ever seen.

[michaeldonoghue]

Eventually, it will run some simplistic version of Doom and then we will have come full circle lol

[saltysoyman]

Ben Eater has nearly singlehandedly shown me how cool it would be to become an electrical engineer!

[atakan]

I'm a student. This channel is a gold mine for me. Thank you for your effort greetings from Turkey.

As barebones as this is, it really just boggles my mind that there is still a lot of heavy lifting being done by the Hitachi microcontroller inside of the character LCD display.

I would love to see a future video where he talks about what's going on inside of that microcontroller to display ASCII characters on the liquid crystal display and process and send out data like busy flags and whatnot.

Like, we don't need to know all that stuff now. Because that's not really in the scope of this lesson, but I would love to see it explored later.

When he was wondering about how to clean the inverted signal I thought to myself he needs to use a Schmitt trigger and then he pulls out the data sheet for a Schmitt trigger inverter. I feel so smart!

[DegradationDomain_stuff]

I have never been so happy to see number 3 in my entire life

[markday]

I appreciate you taking the time to go over turning the per-bit clock into a per-key-code clock a step at a time. Thanks for leaving in the mistakes and glitches, and then showing how you solve them. Those are the practical skills that theory-based instruction rarely covers well.

[yousorooo]

As a software engineer it is very fascinating to see how the hardware works under the hood.

[bensonprice]

On this episode, Ben teaches us how to make triangle and saw-toowth wave signals.

[SamBebbington]

Mounts it in a pc case.
Lemme just plug in my keyboard… proceeds to pull out 4 wires and place them in specific holes in the breadboard mother board.
Done!

[hecker]

I learn more about all of this with him than in school.

[mattc]

Getting flashbacks to my analog electronics class at university when I heard "Schmitt Trigger". Thanks for the psychological trauma Ben :D

[TrapShooter]

I'm always sad when I get to the end of a Ben Eater video because I know it's going to be weeks or months until the next one and I enjoy them so much. Thanks Ben!

[yakacm]

This is turning in to a computer version of Bad Obsession Motorsport, lol.

[Charlie-kzcy]

What could make a Saturday morning better than a new video from Ben?

[Rouverius]

Everyone: They is no way to create a truly random value with a computer.
Ben Eater: Hold my inverter

[minikretz]

For the first time I anticipated an issue! I was guessing that the interrupt would count more than 3 with the 74HC04. I had no clue how to fix it though, and never heard of a schimitt trigger. So I've been learning so much from this video series that I knew there could be an issue and knew what needed to be fixed, but I'm glad that your still showing new techniques to solve problems. Thanks for all the amazing content!

20:00 I "studied" this kind of things at school but already forget about it, but you explained that so well I finnaly understand what that symbol stands for!
