Infrared light may be invisible to the human eye - but it's usefulness in the world of electronics is easy to see. IR emitters & detectors can be used in a variety of different ways - most of us use them for wireless communication everyday. - วิทยาศาสตร์และเทคโนโลยี

Just to put this out there, the word infrared comes from the latin prefix "infra-" meaning below and "red" which is at the end of the visible light spectrum. So infrared is the invisible spectrum that is contiguous to the red end of the visible spectrum.
Collin is awesome, I'm watching his videos for the exact same reason i started studying electrical engineering.
This is pretty much the only reason I watch this channel. That and some of the robot projects.
Thank you for actually explaining things and showing us how to MAKE things. Instead of just hanging out and chatting.
Collin make your own channel so we can get to ultraviolet. This is too awesome.
"Did I just blow your mind.. I'll give you a moment.."
*1 second passes*
"It's true......."
Son of a bitch, I wasn't ready yet!
you need to come back i just found this and love your vids
Great as always Colin!!! Thank You!
Cameras can indeed pick up infrared light and present it as white or purple because the LCD displays don't have a infrared output. So they try to produce the color they see with colors that exist in the display (RGB).
Collin, excellent job here - I agree with others who are encouraging you to setup your own channel. Thanks, Doug
this guy is always awesome!
So it's the electro-magnetic waves sending the information from my remote control to my T.V. The phototransistors in the cameras detect the electro-magnetic waves and that's why camera detect infrared light and that's how the motion detecting devices on the wall in schools and offices and the motion detecting hand driers. Wow! It wasn't a bad thing to learn about advanced electronics and circuitry! I really find it amazing!
These videos are awesome xD
Thanks for the info! I now know how a photo-transistor looks like. :D
You're awesome Collin, make your own channel!
YAY COLLIN'S BACK
this guy rocks!!!.
In my Robotic's Class I made my Boe-Bot respond to the Sony IR Control Codes to allow me to navigate it through a track. Working with IR is very simple :D
@YoWooDDecks Look up the output curves (light output vs frequency) in the factory data sheet to see if a given LED will put out IR.
@FlyHighRC386 I'm guessing a heat seeking missile would have a series of sensors on it. When it's target changes direction each sensor would read a different amount of IR and the goal of the Missile would to always have all IR signals the same so it would probably adjust it's fins until the signal is equal of all sensors (facing it's target) pretty simple stuff. Look up a Solar Panel tracking system, it probably uses something similar to that.
Very educational! You are awesome!
Great video, as always :)
You should really start your own channel.
Yeah this guy is good at what he does. Like him👍
Colin is for the win!
i love velleman kits, nice breadboard, like this kit and i think infared is interesting
i just love these musics
@Archer7Tadayoshi You mean to light up the scene for an IR camera? They do that.
collin, yes you blew my mind.
@LightProductionsTV Collin does have his own channel
@Dri0m you do know that device you made will pickup regular light as well thus making it not as effective
@NightTurkey82 How would it work? What heat is it looking at? And would the heat of the engine mess it up?
That piezo buzzer has how many inputs? Power and GND or more? Anyway, we could control something else besides the buzzer right? As long as the load resistance is equal to the buzzer?
What sort of ranges can you get with the receiver and the transmitter?
Collin could you make a basic guitar disortion pedal?
Could an IR sensor, like the big white one be used for lets say a custom made fuel injection timing computer instead of a proximity sensor? I'm building a home made Electronic timing and fuel injection system for small engines?
Haven't seen one that wouldn't work yet. I've tried several cams from cellphones I had over the years, and several different digital photo cameras. I can safely say that they should all work.
i would like to have seen some bits about the difference between photo transistors and photo diodes in practical application.
when are you going to do the infra violet video
I love Collin's Lab, Circuit Skills, Make Presents, every single Make: video apart from Sylvia's Super Awesome Mini Makers' Show. She's just showing off that she's being famous because of her Awesome father, and that she couldn't do any of this without her awesome father, and that her awesome father has everything I could possibly want, and that her father is awesome! Huhhh... Sorry, I'm just so mad!
@carfansunited He does but does he put Circuit Skills, Collin's Lab, etc. on his channel ?
emitter/detector pair .....(BFF)
nice way of putting it collin :))
Are you guys going to extend the deadline for the Halloween contest another day since your servers have been down for 45 minutes now? I wasn't able to submit my entry from about 8:30 pm Pacific and onward.
Come on, Colin, you're too cool for this Make magazine club.
He is so COOL!
@LightProductionsTV Yeah since there are no "Kipkays" anymore
yes, you blew my mind
2:35 i made this IR barrier from one transistor, two resistors, one IR LED and one pfototransistor,
wow i love technology!
Okay this may sound strange, wanting to make a board of all infrared LED,s , let’s say 2”x2” and I want em to pulses between 10hz to 14hz and make adjustable . How would I make it pulse???? 12v power if possible?
will all cameras work for seeing infrared
is this how heat seeking misslies work? in which case how does tha make it turn the rocket
Collin, you should make your own channel.
We've been expecting you, number 310.
All we missed is kipkay!WEEKEND PROJECT
@sciencething0101 i used IR phototransistor ;P
when are we going to get to ultraviolet light?
Dude ur the Coolest!!!
Collin, I've been told that Infrared LEDs can be used to dry paint faster.
Is this true?
depends on the wattage, you are litterally just heating up the paint. try using an electric heater instead.
hey bro, can you show us how to read logic gates schematic? and put some wires in the breadboard to test it. thank you in advance :)
I
cool breadboard :)
dude you should have been my science teacher, or tech class
@93freestyl93 or he uses it with pc? like me? for games like limbo or bastion or everyt single game thats designed for xbox but got ported for pc?
try explaining the principle of duality
Collin, make a mind data transfer device so i can have your awesum knowledge
Wait, if the long wavelength of red is about 400 tera-HZ, The what about the more energetic, shorter wavelength Violet?
UV is much more interesting. For example, scan your ID or drivers license with UV light. You'll see features that you don't see in normal light. Pass some U.S. currency over the UV light too. Features pop out.
@93freestyl93 where does he have the xbox controller
My cat also did not like the IR emitter alarm. It freaked her the hell out.
LightProductionsTV
ikr!
@everlastingphelps Alton Brown is the man!!!
i find it funny that in school we are just starting to lern about infra red light and ultra violet light. (i suck at spelling). so this video is just more info
Geek-a-lots, you might like "freetrack" (google), (free software foundation) head tracking software that uses your webcam to track 3 IR Leds (for instance, mounted on a head mic &/or ear phones) to track your head position.
Great for 3d racing games etc as you can look around in 3d.. although you still have to look at the monitor.
If you have a good Gfx card (nvidia red cyan is pretty good, if you can't afford a 3d monitor).. then you can Geek-a-lot in VR too.
@carfansunited He has almost nothing on it, there's just his playlists but no Circuit Skills, etc. on his channel
Colin should make his own country!
@thecvideospiczo agree with you my friend, ido.
@hugo6644493 I have been able to see every single IR LED I have looked at. The light is another matter.
I just love you collin, no gay
please make your own youtube channel
YES
you can see near-infrared light
Mother Creator
~~ Loves you ~~
I'm sorry i have bought 2 kit already, and it doesnt work at all :(
Why don't we use UV?
@tibounise he has his own channel .__.
@93freestyl93 nvm ...
now it is
Collin, you are the shit.
@Skyfinity Me too! Apart from Sylvia's Super Awesome Mini Makers' Show. She's just showing off that she's being famous because of his Awesome father, and that she couldn't do any of this without her awesome father, and that her awesome father has everything I could possibly want, and that her father is awesome! Huhhh... Sorry, I'm just so mad!
@reviathon360 O RLY? Can I have a link?
iPhone 4s doesnt pick up ir from my LEDs other phones do like the 4 :(
It's weird cause I can see remote's IR transmitters blinking without any cameras. Just my eyes?
@vivekkumarmalhotra he IS agent smith!he is everywhere haha
@93freestyl93 Again, I always read comments before watching the video :)
Sorry for my moronic comment. After this I'll watch the full video before talking
@TheTiedyeproductions Pretty sure thats been done by Make :x Search it :))
I Never knew cameras can see IR's !!!
what's collin's gamertag?
He's like a nerdy Mr. Smith from the Matrix.
@YoWooDDecks The Infrared LEDs are invisible to human eyes.
Is that the guy from Flight of the Concords?
collin please make your own channel
YEAH!!!!
