Visualizing Data with 7-Segment Displays

Displaying numbers is trickier than I expected! In this video we explore how to visualize the data inside of our simulated 4-bit registers, with the help of the double dabble algorithm and some seven segment displays.

Hi everyone, the new version of the simulation software is now available here: sebastian.itch.io/digital-logic-sim Please note: I made a mistake in part of my boolean algebra explanation, and I've uploaded a quick video to correct that here: kzbin.info/www/bejne/d17ZfYWKnct9arM Also, the 1080p quality setting seems to have a lot of visual artifacts for some reason , so if you're able to watch at 1440p instead I'd highly recommend it!

[@_mickmccarthy]

"This was supposed to be just a short segment" Looks like some scope creep happened and it turned into 7 short segments ;) Absolutely love this series btw, such an awesome idea!

[@shidobu]

it's looking great! I absolutely enjoy watching your videos!

[@graealex]

It's because KZbin gives a lot more bandwidth to resolutions higher than 1080p. So even if you can't watch it at full resolution, the higher bandwidth still makes for a better picture.

[@Yazan_Majdalawi]

@@graealex Interesting..

[@_Gusza]

I really hope that you will not let two year go by before a new video.

[@endermagnet5867]

A while ago, I saw the first video you made which used that logic gate program, and was inspired to make a simplified version of that program. One of the things I tried to make was a 7-Segment Display. Eventually I did it, and while my solution was absurdly massive and overcomplicated, I was too busy celebrating the fact that I actually made a functioning program and made something with that program, and I have you to thank for it. I rarely write comments like this, but just know that even if we don't comment, there are many of us who are inspired by you, whether we're newcomers who have never written a "Hello World!" in their life, or veterans working on their next project. These videos are not only high quality, but incredibly informative, so keep up the outstanding work! Let's get you to 2 million subs next year!

[@SebastianLague]

Thank you, that means a lot!

[@daveturnbull7221]

I have neither the desire nor skill for stuff like this but boy do I find Sebastians explanations both beautifull and educational. Whilst understanding very little of the technical side, I always get a much better understanding of all the concepts. This is all achieved while keeping me highly entertained.

[@blvckbytes7329]

Awesome! Have you thought about uploading that program to GitHub in order for others to be inspired by it as well? I know that you might think that it's not good enough to share, but believe me - it is. It's a start and might help to overcome the barrier of doubt for whoever views it.

[@samadel.a765]

I was wondering around to learn about electronics and soldering And saw this and got curious on how does the 7 segment really works I knew it was binary but god damn it's complexity I only had a base idea

The visualization at 24:06 is genuinely so amazing, it's a perfect way to understand how you can take an algorithm you'd normally think of as imperative and step-by-step, and turning it into a direct pure functional solution

I looked so much into computing and have watched through almost all of Ben Eater's videos. I just wanna say thank you, your videos have been very amazing and have thought me so much and introduced me into something that is my biggest hobby today. Thank you

That's a skill they don't teach you nearly enough when you are learning technical skills.

Just an amazing video! Thank you for keeping up the work on this series. Explaining the 2-s compliment by saying the first bit becomes a negative 8 instead of arguing around with logic gates is something I've never seen before and that just instantly made me go "ohh that's how it works" which a semester of Computer science couldn't... Super cool, awesome work. Keep it up! Also excited to play with your logic simulator whenever it gets released! Would love to design my own cpu with it

[@AlienXgamers]

This video has brought back painfully pleasant memories of figuring out my own 7-segment display maps for my college assignments (One of which I vividly remember watching your video on logic gates to help me understand it), and MAN does it put a smile on my face to just...see this stuff in action and know I can follow along nicely now. Great video as always, and nice graphics too! I wish the logic gate mapper I used was this nice-looking...

This series is giving very strong Zachtronic vibes! The way it teaches binary through simple components which are "boxed up" or "chippified" and reused to build more complex circuits is endlessly satisfying. I feel it would make for a super compelling (and educational) game where you make circuits from scratch and past "chips" to the point where you've made a very complex design, and it's your circuitry all the way down until you get to basic gates

It works perfectly, although it is somewhat slow and it’s also huge. I don’t know if I’ll try building further as it will take a lot of time and be quite complicated maybe this could become a really long project(well technically it already is).

16:10 you can convert any truth table into a huge net of or and not and and gates (a net that litterally just takes every output and gives the exact inputs needed, then ors all those together), and then use some simplification algorithms to convert that to as small of an arrangement as possible.

[@elragonzo6687]

That algorithm part seems to be the tough part though. Such an algorithm is interesting for sure I think

[@grigorispavlakis8890]

Hello Sebastian, just a quick suggestion if I may: On 16:00 where you talk about how the solver works, a better way to approach the problem IMHO would be to get a K-map minterms or maxterms solution and then apply De Morgan's laws to rewrite the expression so that it uses the allowed logic gates only. I have no idea how long this would take (especially if aiming for minimum gates) but it would be at least closer to how a human designer would approach the problem and possibly not need so long to refine to something passable as with completely random generation. Thanks for the awesome vid!
