Collin's Lab: Infrared heart sensor

[Nadrealis]

I'd like to see some coding that would give you a reading of your oxygen saturation by giving values based on color shift.

[454charing]

back to maH laptop

[MrMinimalSWN]

you could run it true amplifier and speakers or maybe use the ms20 filter from your monotron, you could even sample it and pitchshift te signal to the wanted frequency in ableton.

[MRcrAzyProd]

the sketch for the arduino please...thanks!

[Telltolin]

Battle royale anyone?

[jedimastert0810]

you could hook it up to one of those cheap "beating heart" LED kits

[kekejojo1212]

you could put these on a clothespin and have a cheap oximeter

[jdflix1]

You could use it as a polygraph to see if someone gets nervous,

[97273998]

why not use the arduino mega?

[MultiJohn12321]

LOL he still has the Diecimila! SO OLD!!!!!

[BuickDoc]

technically you have a pulse sensor, not a heart senson.

[scientificpages]

G R E A T T H I N G!! !! !! Please visit my scientific pages SPages.cba.pl

[gaussman08]

i love him is so fucking cool

[coconuts739158426]

i would add a red led to the arduino and add a code that makes it blink when the signal goes up so it blinks when your heart pumps

[inspectorcritic]

Can you make a remote heart sensor for reptilian shapshifters. The draw back is they do not have blood. Can you make a remote sensor to detect for bloodless reptilains?????? See reptilians exposed vid

[kd1s]

Cool, a pulse oximeter. With a little coding change you could probably get blood oxygen saturation too.

[Nadrealis]

@kd1s I have a pulse oximeter, but I fear it's cost is probably over $5,000.00 so I'm not opening it up lmao.

[kd1s]

@Nadrealis

Actually all a pulse oximeter does is look at the COLOR of the blood. It's really interesting how they work.

[philotes82]

This is awesome, I'm gonna use this for my scooterputer project, imagine the faces of your friends when you start the bike by touching it the right way ;)

Also it's a security future!

Thanks again for the idea.

[chopperboi89]

Time it for 60 seconds, counting the peaks for that 60 seconds, and that's your heart rate, we have the same kind of thing on an ambulance, it tells us your pulse, and the percent of oxygen in the blood. :)

[dodgedart74]

so im one step closer to the H.E.V. suit ramake from half-life!

[mcmanus1806]

that would be a really good way to see if someone is alive ;)

[pwn0grapher]

For the American fat kids out there thinking that this is the thing from MW2, it isn't. This is a heartbeat/pulse reader.

[chaseantarctica]

lol am i the only one who is a little worried that mw2 fanboys are searching youtube for instructions on making real life weapon attachments?

[MultiJohn12321]

@chaseantarctica mw2 is out. black ops is in!!!

[shebotnov]

@chaseantarctica mw2 fanboys are to retarted for that

[ghilliesuit99]

how do u add range like on mw2?

[B00mHsh0t]

you don't.. cause thats a video game.. :]

[biro753]

@ghilliesuit99 u can use a infrared flashlight instead but for the detector it would have to be like a flashlight too cause thats wat adds range but i dont know how to match up the detector with the right infrared led from the flashlight

[godssonisme]

Tight

[5FSF]

is there any way to add range of any sort for this?

[ThaPrey]

I was waiting for him to flat line.

[Drummboii]

oh i thought he was gonna make a heartbeat sensor from mw2

[myskateboard16]

...

you are a failure

[yahtzeegrandmaster]

i know this is a dumb question but were do i get the code

[AMPBackWoodsStudios]

ya thatss what those things that they clip ver your finger do when you go to the hospital.

[psp12345678998765432]

@AMPBackWoodsStudios They are also on some exercise equipment.

[TIM1TULIAG]

LOL :D

[illustriouschin]

i have been using something similar for a long time to let me know when i'm dead.

[medoaldini]

123

[mcaudle7935]

@medoaldini 321

[sciencoking]

this is the only makemagazine project I ever did myself...lol

but instead of the arduino I used the mic input of my computer and a soundcard oscilloscope program... it worked REALLY well! try it!

[duckvenom]

What's the range on this. Does the skin need to touch it or can in simply break a beam between tX and rX? I'd want to know more to find pratical applications. You could use it for detecting security breach or really pissing off your dog.

[sweftwp]

heart beat sendor in cod5 is crap

[HipHopKiller94]

@sweftwp

It's in CoD MW 2 (CoD 6) !!!

[tobebius]

midi trigger for an instrument?

[SamIves85]

That's what I was thinking...

[zanders247]

Most modern pulse oximeters work with this technology.

[blenderuser]

could be used in gaming, to blur the vision if you get stressed or something.. :D

[SireDean]

ok.. that'd be a really interesting idea... put that with the x-box's new version... the tower or whathaveyou

[SAFEpanki27]

Hello,

can you please show me the Processing program? Thank you.

[ianramil123]

heart beat sensor on modern warfare two! lol

[KingKhronic]

you could atach a beep sound or hertbeat sound to the graph software and evry time the graph peaks a sertin point it would make a sound of your choice

[ghost8605]

make a heart beat detector and stick it on a gun like on call of duty? would that really work?

[coryrbk]

@ghost8605 idk i was wondering that to :D

[suishoujo]

0.o.. where did you point it to get a good recording?? thx

[bent540]

cool

[AZNFlipy12]

we have these at school and you clip it to your ears i think its called a passport

[designer2k2]

voice to silent, music to loud! why is the voice so silent in this video??

but apart from that, nice project :)

[Membrane556]

Neat i think I might make one.

[aphididae]

hi dude, I think you might be interested in something like solianis non-invasive glucose monitoring thing.

it does basically the same thing, but it uses radio waves (and also measures skin resistance) and does this to measure glucose levels.

as for the rest of you guys, no one cares for politics, stfu.

[chrisofcolombia]

Well - the good first: You are obviously a bright lad, and your vids are well done (AND bright enough!). Two negatives from where I stand: You are obviously in love with Arduino microcontrollers - but many of us wouldn't know where to get one or what to do with it, much less how to program one. I'd love to see more non-digital projects from you.

Second comment: the word "solder" has an "L" which is not silent. I challenge you to break with tradition and pronounce the word internationally!

[Plystire]

I think pronouncing the "L" would confuse much more people, not to mention get him a ton more useless comments about it. And, as a matter of fact, the "L" is silent. ... At least for his dialect. :P

[chrisofcolombia]

Hmmm - that's one heck of a dialect, if several million people across an entire country decide spontaneously that they're simply going to ignore a certain consonant that everyone else in the english speaking world pronounces according to regular phonetic usage.

And lets not even MENTION "aloomuhnum" aye? How embarrasing for you all!

I have yet to find a defensable etimology for this arbitrary behaviour.

[Plystire]

If you're from the UK or are British and speak using those english etimologies, then you are probably around people who pronounce "solder" as "sole"-"der", but an american dialect pronounces it with the L silent. If you can't grasp this concept of being from different speaking worlds, then do us a favor and shut up ahead of time.

[SireDean]

haha... i love when people go on dialect issues... and when i say... wait... i was thinkin soldier... lmao.. but hey... i can still use solder i guess... i pronounce it "saw-der" i didn't even notice where the argument on not hearing an L come into play until i read your post... lmao

[coolliger]

@chrisofcolombia

well we would kick your ass in war

go america!

[chrisofcolombia]

Yeah, Stars And Stripes Forever too. Don't you guys ever get tired of reinforcing the classic American stereotype? I am sad to say I got the response I expected: defensive nationalism.

Some of you haven't changed since

Dickens wrote his satire in Martin Chuzzlewit. (BTW - I've never been to Britain).

I won't be replying to any more correspondence, so get off slapping each other's backs and praising up gringolandia if you wish. The rest of the world is mostly bored with your pretensions.

[63NY1]

@chrisofcolombia do we really need 2 insult dialects. c'mon.

[Olirap]

now i think i might go make a medical tri-quater from startrek

[psytrancedan]

I soddered

[Schindlabua]

Colin is awesome, and so is this pulse oximeter

[TriasTheBetrayer]

You can add that to a ring and get a biofeedback of your heart rate, then you train yourself to slow down your heartbeat.

Or you can use that as a pms detector, assuming you even have a girlfriend ^^.

[quaiboi]

i don wanna be rude or anything....but i don like this guy coz he talks to softly....like a gay...(okay maybe only i feel that way)....why cant he speak louder....like kip kay

[burgerking220]

hehe i agree with u i hate him hes lame.

[quaiboi]

lol....dunno why i get so many thumbs down

[Keali1935]

That's the most ignorant thing I've ever read. "like a gay"? You're an idiot. You know what they say about homophobes: They have homosexual urges and are so embarrassed by them that they must try to convince everyone they are straight by acting out against "gays." Who cares what his sexual preference is. Besides, I don't see you posting any brilliant videos. Turn your volume up, moron.

[quaiboi]

well, ur videos are'nt too brilliant as well.....i dont know what the hell is going on in ur stupid dog vids coz it's too dark....c'mon turn on the lights!....can't pay ur electricty bills or what?

oh btw.i wasnt talking to you in the first place....why cant u just ig nore my comments...oh and...notice that i did not use any vulgarities...unlike YOU...why cant u deal with idiots (like me, coz that's what u said) in a polite manner?.

[coldfire152]

congratulations.... u invented a pulse-ox. something thats already been around for years..... wooo

[Kale3193]

yeah and you didnt stfu

[coldfire152]

and he didnt either. pulse oximeters have been around for decades. anyone who has any kind of a semblance of an education would be familiar with them, and since he seems to have one, unlike you, im sure he already knows about them, which makes his claim of inventing a new way of measuring heart rate absurd. his claim is ripping off the work of others that have come long before him

[JINXZER]

@coldfire152 man thats absurd this is just a new do it yourself video, he is not inventing anything new nor, did he say he did. he just said why anyone would wanna measure this.

[collincoburn]

now im regreting my name being collin

nerds

[mozey2]

could this be used as a lie detector?

[agtheking]

Lie detectors doesn't actually work. But is you want to be psuedo scientific and say that heightened pulse(wich can have a lot of different explanations) means that some one is lying then i would guess yes.

[memaxcool]

Where did you get the program for this project.

[bradyfanuno]

nerds

[Nopp3]

damn straight

[TheStyrofoamPeanut]

thats amazingly cool

[sk8trboy4lfe4392]

ha we use the same exact bread boards in my electronics class

[bestSVMS]

how does it work? Is it because that the skin moves up and down when blood flows. Or could you make a heat senser or something.

[farmjunk]

0:48-1:06

It uses infrared-light. Kinda the same concept of how a CD player works

[FranciscoGualMarin]

This is a simple pulsioximeter!

[DeathCail]

I preffer taking a pulse with my hand...

[OrangeL89]

For you COD freaks, the heartbeat sensor there is fictional, and is probably a reference to the Rainbow Six heartbeat sensor.

[guiltynav]

Actually they do have real heart beat sensors, you can find theme now commonly used in a car that cost more the 50g to tell you if some one is in your car or not before you get in (like a burglar). i dont know the extent as in Cod 4/MW2 but they do have them and the one im talking about does not use infrared. it the pumping of the heart by the fluids and and an ultra sound reading.

[obsesedwithpb15]

Might make a pretty decent lie detector?

[gamlman]

this must be like a hartbeat senceor on call of duity

[maglight117]

no it isnt

[GameGuides4U]

the heart beat sensor* on call of duty* doesn't use touch or infrared light. If it did, you wouldn't be able to see through walls with it =P

[gamlman]

wtf?

[neal40000]

you blondes are too dumb to know how to have naughty fun, especially when your a korean man contantly spamming youtube comments.

[SsessiBabi91]

weiss das passt nicht zum video aber ich suche leute zum quatschen hab auch ne cam

[cobweb93]

Ur mom

[assailant85]

I have a good idea for using this:

give it the girl on a first date and let it transmit the dates to your bluetooth cell phone, than you can see how excited or bored she is when you're talking :D

[shivoskate]

virgin fag

[Parubhi]

And you are a burger flipping slut? You should try to think above the high school level for a change.

[jayls5]

It's called a pulse oximeter. You can buy portable ones that not only show the waveform, but they also display the % of oxygen saturation in the blood (thanks to the light absorbing properties of hemoglobin). You can get them for about $60-80.

[amando96]

mine doesnt work :(

the graph changes acording to the IR light reflected off a white sheet, but not with an artery, maybe its because i have low blood pressure? or maybe my resistor has to be higher...

[foxyb69]

Thats pretty nice!

Would be great if you could get an audiable output for sound effects. A lot of noise is generated when using a mic; I would imagine this is cleaner.

[deleonleandro]

Have you ever heard of cutting your nails?? :)) :|

[FailedSquare]

... those are average length nails

[fronkenpoop]

This is great. Thank you for the very interesting video.

Bio-sensing data is great for a number of different things. I recommend watching a program, "Prototype This" Season 1, Episode 1, called "Mind Controlled Car". In this episode the team design and make a car control system that disables the vehicle when the driver is enraged, to avoid road-rage. A futuristic concept and design depicted in this program that is fun to watch and and thought provoking.

[Vitahero]

Awesome, that there are also people who are presenting interesting stuff on youtube and not only their new makeup or other extreamely stupid shit!

[Taleffs]

make more

[Jonas412LOL]

you could use it to see how scared someone is when they see a picture. Or maybe as a key only the most relaxed person can enter.

[grovyle05]

Actually, you could use it for a lot of things. With a few modifications (like making it water-tight) you could probably track ocean currents or underground tremors.

That's definitely one neat piece of technology!

[imemutch123456789]

it could be used to make something like a tricorder off or star trek to help medical people diagnose heart rates out on the field or used in a bio-bed (again from star trek) to cut down on the large equipment and if it can be used at a bit of a distance it could also be used to detect life signs from someone you can see yet cant quite get to the medical usage is limitless if you think about it

[Necrosis57]

Turns out that's not how it works lol. Medical usage is not limitless, it basically has one purpose: track vitals of one person you have physical contact with. And! They actually make these, I don't know if you've been to the doctor lately, but that thing they put on your finger to check your vitals is something like one of these!

[sxdemon]

Instead of calculating your hearthbeat while running with your finger, you can use that device to calculate it.

[hazem3008]

Make a heart beat sensor like in Modern Warfare 2 :D?

[KebyMilla]

that is exactly what I was thinking lol

[sk8amped246]

wow lol

[KitsuneNiwa]

@hazem3008

I'm glad I'm not the only one that thinks/fears of the possibility of a heartbeat sensor armed weapon ...

[123woohoo]

call of duty modern warfare 2 :)

[r0b0leadr]

when it displayed the heartbeat using the little graph thingy I had the video int full screen and it looked like a screensaver

still a pretty cool device

[modoran2000]

you could incorporate the sensor in the door handle, so when a burglar touch and push the handle, then the high bitrate of the heard could trigger an alarm or a web-cam photo

p.s. problem when you come from jogging :D

[armadica10]

What if you used sound detectors to pickup the pulse of he heart. It has 3 sensors that using a computer to detect

and position the sound using the differenual of he sound. Idk if it would work but if it did you could locate a person or several people before you go into a room. Military applicaions "if it works and it alrready hadn't been done"

[ahetza]

awesome..as usual

[drakeconstant]

thats cool

u can make a change

that will be usefull for vets docters and crap

[BungaEBiker]

Well beam me up Scotty. That could very well be the great, great, great grand daddy of the sensor that McCoy used in conjunction with his tricorder. Humm now all we need is a Hypo spray.

[mostliberal]

Actually I was thinking more in line of Star Trek Deep Space 9: use it to detect people without a heartbeat (shape-shifters).

[JackDigital]

Wouldn't work. A competent changeling can fake a humanoid heartbeat.

[pyro1324]

Use it as a lie detector ^^

[OCDADVENTURES101]

what happened to bre pettis?

[pyro1324]

I wonder that to.

[geoferret]

As an EMT-Intermediate who uses this technology everyday I can tell this is your basic Pulse-Ox device, without the actual reading of oxygen amounts in the blood!

[woefulparsley]

that's pretty awesome

[ernestprado]

Cool

[tetranoob]

would an infrared emitter/detector from a discarded dvd player & remote work for this?

[youngnewtonian]

The IR of remote control will work. As for the detector, I am not sure.

[kzshantonu]

I think so, YES

[WETBRICK]

if you make two heart sensors with sound it would be possible to hear heatbeats of two people syncronize.

[EmancipatedSquirrel]

could you post links to the programs you used to read and graph the data?

[free2fredy]

Hmm interesting wondering if the graph would show max heartbeats per minute or max ox

[keyboardbandit]

In the ER we use a device called a Pulse Oximeter. This uses infered to measuse the percentage of oxygenated blood running throught the capilaries in our skin. If you are ever getting your vital signs measured and they put a little clip on your finger that takes your pulse and has a little red light on it, then you know you have a pulse oximeter on your finger!

[sk8erdudejustin93]

ha MW2 heartbeat sensor JK but that would be SOOOOO cool

[naruking11]

when the light hits the phototransistor, the the transistance (or what ever the measurement is) changes. but how the change affect everything before it (as in the power going into the analog input) plz answer!!!

[kd1s]

And you can also modify the code to get the actual blood oxygen content too. That's how the professional units do it, bounce infrared light into the skin and then do a calculation based on the reflected light value.

[TheTarrMan]

how about a video showing how to make a polygraph machine. The Infrared heart sensor could be a good way to measure the hart beat so that's a good start. (just an idea)

[razorflown2]

Awesome. This guys vids are the best. ive seen some pretty lame stuff on make mag.

[buggyiscool]

heart beat detector from COD6!!

[briackman]

i was thinking the exact same thing!

[munkylad545]

you mean mw2

[buggyiscool]

lol so its branching off now???

[frebel93]

new music dude

[vivalorraine]

lie/stress detector

[djjor3l]

[hermitcrabstuff34]

your a nerd

[lolman12334]

you say that as if its a bad thing, I say stand proud!

[ilikemagic52]

spelled you're wrong. jesus christ people, learn basic grammar.

[hermitcrabstuff34]

close enough

[shadowblack1987]

Jesus Christ**

[GmasterFunk]

You forgot to captalize your first words, and pronouns.

[Dallouez]

Watch your mouth pig! Why should people l;earn how to spell this isn't a english class you moron. Besides they have idiots who are anial rentative like you stalking youtube, Need help reading and understanding ask your mommy littel boy!

[ilikemagic52]

i didnt understand most of that.

[nickandbristudios]

i fucken hate it wen ppl do that! it pisses me off! ur totaly right! much respect

[kd1s]

For biometric scanners to be sure you have a live human.

[7410n0]

Oh gosh darnit! I guess all those cadavers in my basement just won't do :(

[PanWitSyr]

Good to know. Thanks for the tip kd1s!

[godzuki101]

LOL, the amount of things this could be used for........ personally i'd be installing them on tredmills and excercise equipment not only would it be a good way to really measure your heart rate, but it has a GRAPH, everybody likes watching graphs. Do you really think people invest all that money, just to make money? NO, they like tracking the "WORM".

[dcallstar51]

use it to shoot people in the dark..

[nagoia1984]

virgin

use it as a lie detector. lies raise the heart beat. :)
