Arduino EMF detector

[MrDeivi65]

puedes hacerlo con la placa maker shed?

[MrDeivi65]

donde sta el programa?

[TheTBagHour]

How do you update the code for the LED bar graph?

[MrDeivi65]

¿donde puedo encontrar la placa de los elementos vacías?

[jack002tuber]

Can it find ghosts? What about a bug? (hidden transmitters)

[cubanpyroman]

ITS NOT A 3.3 MEGAOHM RESSISTOR. He uses a 3.3 kOhm one.

[KC2VDM]

@cubanpyroman I'll try it, but i definitively heard 3.3M

[cubanpyroman]

@KC2VDM

You can't find any 3.3m. At least i can't. Using a color chart people are saying that he uses 3.3k. Haven't checked myself though.

[PatrickWTB]

Were can i download it ?

[hyper080]

@PatrickWTB here blog.makezine , com/2009/05/15/making-the-ardu­ino-emf-detector/

[KC2VDM]

Can I substitute the 3.3 Meg resistor for something of a smaller value? I don't have any on hand at the moment O: Would 470k do the job?

[gabrielinfante]

to measure continous fields you can use a hall effect sensor

[Karate97100]

What is the sketch to the Led bargraph EMF Detector?

[cwasc]

Supernatural anyone??

[MrXerax300]

good for ghost hunting on a abandoned buildings

[aei05h1]

Excellent! Now make a tricorder ;-)

[sweettooth80]

can you build a smaller one?? i like to see that

[Stra2M]

coolcool!

[kp2sushi]

"do not insert into outlet"

[Jhfgsjdcd]

why you no make own channel

[MaxVolumeProduction]

How can you hook a speaker to it so you can hear the waves? and also what about a LCD screen good Idea or no?

[taostoner1]

What about your brain?

[MishterChrishtopher]

how do you make a nail clipper?

[TheNoPig]

you can also use a AM radio on band 3

[uniqueandprosperous]

will this board work as a scalar wave detector?

[RoGeorgeRoGeorge]

"...using an Arduino microcontroller."

@makemagazine: Arduino is NOT a microcontroller.

[Rbt208]

DIY ghost hunting.

[raxaxaganaz]

@Rbt208 I like this! SUPPPERRNNAATTTUUURRRRAALLLLL~

[russotragik]

you can detect ghosts?

[saeidkermanshah]

Cool one...can you tell me what is the idea behind it? what that probe is picking up and to what level?

[sweetgyy]

hmm i'm more impressed with your silly music haha

[agentkapser]

going for ghost hunt now

[ruskey101]

youd be better coiling the wire as if it was a elecromagnet

[spartan13014]

Can you made it for radiation?

[randomness2101]

Code please :)

[289359752]

such a geek! LOL

[idrismaster]

MAX level virgin

[waxmuth]

Cut your nails please!

[PAVELNEKULA42]

1:16

What is it?

[thegoodhen]

@PAVELNEKULA42 Arduino prototype shield (from adafruit).

[myzaratustra]

las masas de la barra de leds estan unidas dentro de la barra o las unió por debajo de la plaqueta?

[sciencething0101]

better idea use radio shack mini amp 15$ then get coil of electromagnetic wire then just plug in wire to audio jack then to amp you can hear the eletromagnetics fields frequency and the intensity then if thats not good enough plug it into ardunio

[FukUrselfHard]

Wait, let me get my plasma gun!!!

[jabiv25]

Awesome...thanks!

[BrutalSnyper]

Otherwise awesome video :)

[BrutalSnyper]

You need to cut your nails :o

[Firehowk]

didnt find sutch a high resistor :(

but a diod in reverse direction works aswell :D

[hydrolisk1792]

Might as well make a Tricorter :)

[xevilstar]

add a geiger counter sensor and temperature sensor you are beginning to have some kind of ghosthunting device :D

[cyctechproductions]

awesome you can start looking for ghosts that way

[rccarz5]

where did u get the led bar graph

[crionro]

Totally did this, fun and simple project.

[enticed2zeitgeist]

What wire stripper thing is that?

[OtterWater528]

You uploaded this video two months before my birthday.

[Wildal2000]

How much does it cost?

[matthewtchernev123]

you uploaded this video the day after my birthday

[TechnoMaple]

Make it detect WiFi

[nicexe]

@TechnoMaple Just use a 0.125m long antenna

[MattblahMatt]

Do you have a girlfriend?

[Lwrlukas10]

I was wondering if would put in a sound detector arduino

[jedimastert0810]

It's like hide and go seek!!!!

[MadmanDKDK]

I really doesn't know much about Arduino programming, only web programming.

My question is, as a programmer, would it be possible to program the LED bars, to show bars according to how much current or whatever type of electricity is detected with the probe wire ?

[myguitardidyermom12]

Do not insert into wall outlet.



[Hug0agogo]

Should this only detect AC current (or rapidly pulsing DC) , if i understand the design correctly that's all it should pick up if not what am i missing. (also this would explain the very low reading on the laptop)

[supallama]

make one with the bar LED for me? (including programming and such) I have no problem paying

[bergerlemur]

Any Telecommunication Techs out there thought about making a tone and probe /tracetone out of something like this?

[Fomelogo]

Oh my god you are so intelligent.

could you help me? is it possible to make a "charger" for my public transportation pre-paid card? i would buy one if necessary

[shelterbuddy]

Cool. Pretty scary that so much stuff is floating around in our air!

[MissMopPop]

where can i get an arduino board? 

[eleftherios11]

@MissMopPop sparkfun is your friend

[xufuxtyle]

perchè se metto la resistenza non va e se la tolgo si?

[MatrixOfDynamism]

when will you ever use ARM processors anyway?

[MatrixOfDynamism]

what is the biggest potential difference that can develop by using the wire?

[Milegolasss]

Does anyone knows how the arduino can detect the emf?

[matthewtchernev123]

i never tried to ask something like this but can you make a water bottle flashlight

[MrEinstain]

@matthewtchernev123 of course you can! just wire an led a power switch and a battery pack into a bottle!

Oh,and paint it black.

[matthewtchernev123]

@MrEinstain i kept it clear because it looks cool looking inside

[MrEinstain]

@matthewtchernev123 Good job! Keep on building things like that and you'll be able to build your very own nuclear bomb with easy! LOL

[jayiscool723]

@matthewtchernev123 yeah just put some LEDS and a batteruy in a water bottle....

[thegoodhen]

@matthewtchernev123 Not really that hard. There is just a problem with switch. I reccomend using magnetic switch and magnetic bracelet mounted on bottle. That way it'll be 100% waterproof.

[DaAlexboiii]

@matthewtchernev123 ask that idiot kipkay he does the impractical stuff

[pinguinociccione]

There is a backgound mistake: a monopole antenna like the one you made with that wire does NOT pick the EM field in the direction of the wire, but orthogonally!

Its radiation patter is something like a donut around the wire...

(telecomm engineer)

[Mozza5555]

made this and it works...so cool

[Launchapproval]

just use a shortwave radio

[turkanator123]

OH SHIT I GOTTA MAKE THIS!

[veroboardcom]

I like the "1st person shooter" style of video

[JDFromSac]

i dont like you



[jackdoble2]

it works!!!!!

[chipko]

LOL! "Do not insert into wall outlet"

[xXJeeXTeeXAyeXmanXx]

@chipko some idiots would try it! lol

[chipko]

@xXJeeXTeeXAyeXmanXx you are unfortunately right :)

[misqisz]

arduino... can this circuit detect the unintentional radiation that emit from ict devices?

hope that you can answer me ... thank you

[xamranshamsi]

Love the videos keep it up! Where can I get your music?

[HeerBadkuip]

While this project doesnt prove the presence of an EMF (uploader do your homework!), this tool still could be used to debug some 'strange' errors that you get with some particular electronic devices you may have made. Electronics (above all analog parts) are very sensitive to strong electric (-magnetic) fields. This video also shows off that there is a very good reason why your computer is surrounded by metal casing.

[mikkelhougs]

It makes sense if EMF stands for Electromotive Force rather than the Electomagnetic field.

[defzonoc]

sorry all it is an electromagnetic feild detector theres no difference in magnet magnetic feilds and electric ones and plus this can detect DC feilds as the sensor moves closer it will pick up the change in the feild and if this guy is smart hes using the MCU to pick this up and make useful data about the feild its sort of like using accelerometers to measure speed. you monitor the acceleration and figure if its force is this much for this long its going this fast. not ment for it but can be

[novachevyguy]

is this guy like fifty years old or just a costar on the planet of the apes movies??

[nwhiggins]

you dont need a microcontroller to detect E-fields. All you need is an opamp and a small inductor.

And this is just and electric field detector (not electromagnetic)

[lesleyhenriquez]

Beatles are somewhat out of fashion, and so are their hair and beardstyles. Did you know this?

[pantatnenekko]

hey, how can u do those \LED display goes up and down? thank you My lord ^_^

[Frajedista]

Pretty cool.

I have been working with arduino too :D

If you want to see my videos with robots look at my channel :D

[eggandpieman101]

i dont have a 3.3 meg ohm resistor

can i use a different kind of resistor

[NoJake]

This totally needs Jaws music starting @ 1:40

[eggandpieman101]

You said to use a 3.3 meg ohm resistor but you used a 330 k ohm resistor.

Is it the same thing?

[TheKazooBot]

sweet build collin! quick question though... any reason why my old records would give off emf ?

[jimthechimmneyman1]

is that plugged into the computer?

[seversic]

i watched 3 mins n 20 secs of a guy getting a boner off of a arduino EMF detector

[6x6F]

This is too complicated and expensive for what it does. Why can't people keep it simple?

[fourthlifeproduction]

@6x6F its an arduino shield.the sheind costs nothing but spare parts.auduinos can do almost anything with programing.

[TheMagicalTouch]

can you make an EMP detector??? so i would know when a nuke goes off :D, because it emits EMP waves.

[thewlli8]

@TheMagicalTouch hmm i dont think you would need an emp detector to know weather a nuke has just gone off =/

[fourthlifeproduction]

@TheMagicalTouch no, when an EMP goes off it gives off EMP waves, and if an EMP went off aroud this toy, the leds would get so hot, they would melt the pcb.an EMP is a pulse of an EMF.

[dolly2078]

Which is the best material to be used as the antenna?

[gaussman08]

microwave ? NATA

[hegyimutymuty]

there is somethin' strange in the neighborhood, who you gon' call? GHOSTBUSTERS! :D:D

[DriftKing6095]

hey what the **** happend to kipkay???

[nikonfseries]

@DriftKing6095  Kipkay is not the only person on the make netword... dickhead

[Zoasterboy]

@nikonfseries

chill bro

[jpiramirez]

If your LED bar has a common cathode or anode you could use only one resistor

[jenn011754]

Dear Collin, I wanted to ask would this work as a metal detector? If not, could you recommend an Arduino circuit that would work. Thank, Merry Christmas.

[josh22920killer]

kipkay is better

[kctess5]

super cool

[drumid1881]

do not insert into wall outlet!

[soothillstott]

Well,just like the device in 'Super Natural' for detecting the devil....

[TD47]

Cool project and awesome chops!

[666alberto]

Bellissimo! how much?xD

[station2station]

You should now add a piezo speaker to output sounds similar to that on a PKE meter... heh you can walk around and pretend you are finding little voltage ghosts...

[Dark0Lord7]

@station2station But speakers use magnets, so they will cause interference.

[beasterG11]

what kind of baterry are you using to power the arduino

[detibry]

you could also make this with an op amp.

[gandulfo77]

Sorry, but this is NOT a electroMAGNETIC field detector.

[kyCap222]

@gandulfo77 who cares its cool besides show me the defenition



[webmastertool]

@gandulfo77 I think it's the same thing.

[dumle29]

@gandulfo77 why not?

[gandulfo77]

@dumle29 Because all he's doing here is allowing electrostatic fields to be coupled to the A/D converter of the Arduino's analog input.

Do you really think you can detect magnetic fields with no coils, or no hall efect sensors???

[dumle29]

@gandulfo77 well, yeah, alternating magnetic fields, would generate some flow of electrons in the wire. makes sense to me.

[gandulfo77]

@dumle29 So, get your Arduino and try it!

Then tell me how good is detecting magnetic fields ;-)

[dumle29]

@gandulfo77 sadly doesnt have an arduino :' (

want one though, just dont know where to get them here in Denmark :(

[gandulfo77]

@dumle29 You can buy it at eBay.

Arduino is a cheap and GREAT prototyping platform. I think it's the best one!

(I have four: Tini, Duelmilanove, One and MEGA)

[dumle29]

@gandulfo77 thanks. but kinda expensive when im not sure if i can code for it :S

[swss12]

@gandulfo77 these changing electric field produce a magnetic field... as per maxwells equations....

[xXJeeXTeeXAyeXmanXx]

@gandulfo77 yea, its probably EMF, depending on the use. if you mean for "ghost hunting" then this is not the right thing to be using.

[GoaTseTung]

@gandulfo77 Care to elaborate?

[7cle]

@GoaTseTung care to read the info provided ?

[wurzelmnnlein]

@gandulfo77 it is

[MatrixOfDynamism]

@gandulfo77 WHY WHY??

[lHenry97]

@gandulfo77 Then what is it?

[kriptonis]

@gandulfo77 Since the basic energy type is electromagnetic, and there is no magnetic energy other than electromagnetic, then this is in fact an Electromagnetic field detector. It might detect only some electromagnetic fields, but the uploaded didn't spoke about it's sensitivity. Of course if the field is too low it will not detect it. But it's still an electromagnetic field detector. All electromagnetic energy is the same, magnets, wires or electromagnets.

[mattx12345678]

What arduino board is best, The Arduino Duemilanove or The Arduino Uno? The website that i went to said that the Uno is a replacement for the Arduino Duemilanove. They both cost the same so which do you think i should get?

[ezman700]

@mattx12345678 The Uno has slightly more memory and it can also provide feedback to the computer, like if you were going to make a computer mouse. It's a $5 difference between the two, so you might as well go with the Uno.

[mattx12345678]

@ezman700 Thank you. i have been looking around and found a good deal with the Duemilanove as i only want to make some simple projects to start with. thank you for your advice :)

[yodathepimp2]

I think I should get an arduino some time.

[juicebab]

If I'm not mistaken, I think this one detects electrostatic charge. You can probably achieve same results with a FET, an LED and a battery.

[AWdrius]

Very cool project.

[shorishel]

once u uploaded the code on the Arduino, can u disconect it from the USB and still work ? what about a power supply ?

[Gr4nti]

@shorishel you can see at @1:09 that it's powered through the barrel power input (probably a 9V battery)

[theyearofourlordig88]

I USE THIS EMF DETECTOR...WHY? BECAUSE ITS...

UNBELIEVABLE....OHHHHHHHHHHHHH­HHHH
