Binary Decade Counter
February 18, 2026 • EPISODE 298
How do integrated circuits actually work? In this episode of Science LIVE with Roger Billings, explore the fundamentals of integrated circuits with a closer look at a binary decade counter and how it processes and counts electrical signals.
Learn more about the Acellus Robot Dance Contest and Acellus World, coming to Kansas City in May 2026! And get ready to discover fascinating science in the natural world—from hydrophobic spiders that repel water to the surprising fact that rainbows include invisible colors beyond what our eyes can see.

Hi from North Dakota
I love that new little robot! So cute!!
How many years can a spider live for under the water?
Did R51 use Suno AI to create AC-D2’s song? I’ve known that many AI-generated songs are made using Suno, so I’m pretty sure it was.
thank you for this weeks sience live!
bro that doesn’t work in real life I mean the really smart drink
Hi from Texas
This is so cool.
hello guys this is so cool
Dr.B I have a serious sad question for you Have you ever heard of a powwow even though it’s not a really a sciencey question could you please answer. :>
Oh my god, the Acellus Teacher Serum. LOL
I did not know what Hydrophobia meant. Science live is so educational
I ❤️❤️❤️ the dancing robot!
😊😊😊
So cool
very interesting video
Question: How does a water spider live in water?
hello from nc, looks so fun!!!!!
Should of been more careful
greetings from peruu, loving this
I am so excited about Acellus World live Science fair!
You make science more interesting!
Today’s video was great!
hey from texas
Hi from MT!!
What is an Intergreated Circuit?
wow that’s great
Greetings from N.C. Great live tonight as always, I enjoyed the dancing robot and AI presentation. Thank you to all for the continued efforts each week to make these possible.
loved this
I loved this lesson, learning about integrated circuits.
R-51’s gonna be mad.
I learned that an intagrated small circuit is a circuit that has really tiny transistors in it
Is it possible to build that in under ten minutes?
the lives are amazing the watch
The Dancing robot was the best.
Watching from KY. Nice robot 🤖
Yes this is absolutely great!
i love arer 51
I love doing Acellus do to the flexibility!! it makes it so easy to be able to do other things like thetare, get a job, and other things!!!!
I am enjoying this vid so far! I loved it when the robot danced. *

that robot is cool!
Can you have the protoges teach a course or give them a course?
Hi from Alabama
How long would it take to put that together??

How did you make the robot dance?
Mr. Billings, if you do not mind me asking. Roughly how much does it cost to mass produce those amazing robots?
The dancing robot was so cute
The robots so cool!!!
When did you first make a robot if you did, then how many people did it take? And, how many tests do you think it took for it to fully work?
dancing robot!!!! so cool!!
I love robots, they are so funny.
I did not even think the rainbow was different temperatures 🤯
i love these guys they are so funny
I love Science Live!
AI songs and a 3D printed robot. Thank you Acellus
Prepare to laugh and learn.
