Over the years, I have enjoyed Collins videos. Collin has a hip coolness about him. He kicks butt! MORE.

[@dandearman2871]

It's nice to meet someone you can talk hex with. Thank you for making very clear the Ox in front of a hex number.

[@robertschulz6558]

This is one of the best educative videos i´ve ever seen. Not too fast explained, handy, and a little breeze of humor. perfect!

[@jvegar08]

i love collins lab ^_^ i wish it was a weekly show .... i look forward.... as is its like a surprise christmas gift that fell behind the couch and gets found 3 months later ^_^ thanks for all the great shows

[@MI-lo2hj]

weird...

[@GavinRemme]

Collins Lab is the best!!

[@isaiahnelson3643]

For the love of electronics, can we get some more freakin Collin around here!?

[@domobrah2671]

He's so calm and collected

[@soghrahassanloii803]

he is great. wish i had such a teacher when i was teen

[@tedvanmatje]

"decimal is a fine system....quite popular, if you haven't noticed...." lmfao!! collin, you're a legend!!

[@Oshbotscom]

An easy way to read binary numbers: Binary Number: 0 0 0 0 1 0 1 0 ----------------------------------------------------------------------------- Value of each number: 128 64 32 16 8 4 2 1 And the pattern continues to the left, doubling each number for each additional place. Then you add up all the numbers that contain a 1. So in this example it would be 2+8=10. Hope this helps. It made figuring out the value of binary numbers easy for me.

[@RealationGames]

Programmers also mix any of the notations when it's useful. For example, when assigning data to shift register, it's easy to see how binary is the most intuitive choice: "B10110011" vs. "179" to describe which LEDs are ON: ◦•◦◦••◦◦

[@Falcrist]

Binary is also very useful when using port manipulation on arduino. www.arduino.cc/en/Reference/PortManipulation

[@thegardenofeatin5965]

+RealationGames On the other hand, when inputting a list of values, it's easier to say "0xE4 comes after 0xDA" rather than "B11100100 comes after B11011010"

Colin, I've sincerely missed your videos. I am so glad you left Make: and are continuing your phenomenal work.

[@-Rook-]

One of the best explanations of binary and hex I have seen. Well done sir.

[@TheRangeControl]

Collin, Please accept my apologies for my noob question. But, here goes: You showed us how counting to 5 or 6 worked in Decimal. Please explain how you find values in Hexadecimal. At the (3:34 Time Mark) I was under the impression that I should multiply the values of "F" & "C" to get a value of "252",considering that the "F" & "C" were side by side... However, I received a value of 180. Unfortunately, I need more than just the table of values. I also need how the value is calculated. Grateful appreciation (in advance) for your response, Collin.

[@cosmosliger]

I'm not Collin, but here goes: The way it works isn't actually multiplication- it's powers. In regular decimal, you have a 1's place, a 10's place, a 100's, 1000's and so on. They are powers of the base - in this case, base ten. Sooooo... in a base 16 (hexadecimal) number system, rather than having 1's, 10's, 100's, you have places that are powers of 16. This means you have a 1s place, a 16s place, a 256's place, a 4096's place, etc. Thus, just as decimal [2][5][2] has a value of [2]*100+[5]*10+[2]*1, the hex number [F][C] (which is really [15][12]) has the value [15]*16+[12]*1. This works out to 252. Thus, to work out a hex number such as 0x1A426C, which is [1][10][4][2][6][12], you would multiply the first (rightmost) digit by 16^0 (1), the next by 16^1 (16), the next by 16^2 (256), the next by 16^3 (4096), and so on, and then add it all up. Thus you get [12]*1 + [6]*16 + [2]*256 + [4]*4096..... = 1720940. Hope that made sense :)

[@TheRangeControl]

Somehow I just received notification of your response. But THANK YOU!!! Not only does it make sense, but it leaves me distraught as to how lack luster my skills in Mathematics are. :-D

[@wiinick90]

Love this guy. Explains everything perfectly.

[@Sch1sMx]

great video and super helpful for my class, plus the professor looks like a fusion of Rogue from Xmen and Dwight from the office. keep it up

[@terminator557]

This brings back memories of my first week in Assembly.

[@sunilkumar-ls2yb]

Thnx so so much brother You cleared one of my biggest doubts ...that 0x means hexadecimal Love uuu

[@SteveWeinrich]

Pedro and Noe Ruiz - What software did you use to create those amazing animations? The text overlays were fantastic and I'd love to learn how you did them. Can you share your techniques?

[@subhranshudas8862]

Awesome explanation! Need more of these!! i had few doubts - 1) when you say 1, 0 are stored as electrical charges, is there any way to explain how exactly that happens? like say i declare a number like, int x = 10; how is it stored in the memory as charges & retrieved back again from charges? 2) how are memory addresses which are in hexadecimal understood by the machine in the context of 0 & 1 Thanks!

[@RafaelScott]

AWESOME! More Collin's Lab, please!

[@thegardenofeatin5965]

+Rafael Scott G. M. presents a very compelling argument.

[@greypoet2]

Learned to do Binary in high school, (long, long ago) and would love to be able to do Hex. Colin, pleeease?

[@josepvabr1593]

Wonderful video Collin. Great work!

[@JesPulido]

I love these vids. The illustrations are very helpful.

[@Desmaad]

Some programming languages can use a wide variety of radices (bases) with various notation. My favourite is Python, where you you define a base with a prefix consisting of the base number and an r (Erlang is similar, but it uses a #, instead.)

[@krushfinch7430]

Great vid. The section at the end pointing to other labs does not have a link. When you click, it just stops the video.

[@adafruit]

Annotations updated!

[@aemerox5773]

This video kicks ass.

[@bpoole007]

Love that audio pre and post content

[@moyrml]

It really is turtles all the way down. 42 turtles make up a bit. Excellent video!

[@salihsendil]

This is an awesome channel!

[@BritishConcept]

These are the best. You should do one on transistor computers and logic gates :D

[@YeahItsThatBad]

This was extremely well done!

[@mindscapechronical]

I want more of Collin's lab :D it's the best !

[@HemantSalunke143]

Perfect way to Explain!

[@teslabamf]

Can Collin just do all the videos on adafruit now? K thanks.

[@Brian250609]

thanks for all agent smith

[@nfijef]

We miss ya Collin!

[@johnskyrim]

I subscribed because of Collin!

[@kulgan96]

i am studying to become a network engineer this took 5 minutes a one of my lectures took a half hour when you teach i get intrested and not sleepy

[@sagarmajumder9527]

thank you sir love from india

[@CarryShout91]

very coherent, very helpful ...thank you :)

[@DaedalusYoung]

I remember octal was quite popular too a long time ago. Whatever happened to that? Was also very useful when making nerdy jokes, such as: Why do programmers celebrate Christmas on Halloween? Because 31 OCT = 25 DEC!

[@rty1955]

Octal was popular on Minicomputers like Digital Equipment Corp. (DEC) family if PDP conputers ir VAX's Some mini computers also used byte-octal so a 16bit number qould be reptlreaented like 177177.

[@braddahreid]

Do you know of any good books or literature about binary and hexadecimal?

[@mdasilvac]

Very clear, thank you!

[@nurzazin]

great video..

[@Cybeonix]

Great explanation :)

[@oz4232]

excellent..... Oz from Turkiye

[@mysticalsoulqc]

wow that is so cool. great vid!

[@strawhatluffy4257]

what coding language do you use

[@chrisleech1565]

Collin where have you been pal? We miss you

[@dawson345]

More Colin!

[@sithiradissanayake3940]

can you make a video about logic gates....?????????

[@sumithkalyank1623]

awesome!

[@MartinEcheverria98]

Nice!

[@sonofsam3456]

Love the hair

[@justinm3747]

"Bytes all the way down." Was that a reference to "turtles all the way down?"

[@rlsimpso]

You beat me to asking that by three years.

[@imho2278]

Why would you think that??

[@joemuis23]

what is this song called?

[@Markevans36301]

Great little video but it left me scratching my head to why you skipped octal?

[@Markevans36301]

***** you are probably right that me wondering shows that I am an OLD hardware hacker. Arduino responds to octal just fine but probably set up that way for people like me!

[@rty1955]

Octal was uaed on mini computers like DEC PDP and such. Its not used much any more. Unix was developed on. PDP computer so a lot of legacy software uses Octal representation

[@adamparker5027]

hey nice cutting

[@xanokothe]

YEAH! COllins!

[@JovenAlbarida]

Much easier to understand

[@akalakahsmoob]

Music so good, it's distracting. 👍🏼👍🏼👍🏼

[@Tardisius]

R U MIB ? or MATRIX SKP? =))

[@Nicbudd]

Septimus, if you see this, adabot doesn't kill babies and uses them as slaves.

[@imho2278]

The temptation to modify Roman arithmetic...where MM = 2000....and in binary/hex.....you write it out. Roman is so much shorter....

[@AKTheREal]

So I’m just staring at 1’s and 0’s while I’m on my phone

[@sirulrich894]

~that's good~

[@Craby-YT]

Freaky ahh teacher talking about bits

[@domobrah2671]

wow... i... i... i get it!

[@ursonate]

i totally did not get hexadecimal before this :P

[@JmChadillonProduct]

RIP hair.

[@VAX1970]

It's hanging on for grim death

[@starcitizenmodding4436]

cool

[@MysticalDork]

Roses are 0xFF0000 Violets are 0x0000FF All my base Are belong to you :3

[@shokobata]

explain 8 bit computers

[@rty1955]

What would you like to know about them? 8 bit conputers simply used 8 bits internally as opposed to 4 or 16 or 24 or 32 or 64 bits

[@nThanksForAllTheFish]

haha, bits and turtles all the way down...

[@cesarjhony]

Pensa num homem feio.

[@PapaMead]

ADABOT is a menace. He kills babies and uses babies as slave to destroy the world. Why would u do this ADABOT! WHY!

[@HazeAnderson]

DEAD BEEF

[@Nightstalker350119]

Hey you forgot to mention big endian and little endian.

[@rty1955]

That obly pertains to how CUPs process info not numbering systems
