Using your smartphone as a metal detector!

[Digdeeper2]

Hi All,

I'm new to TN. Been reading a lot about MDs but recently came across a video on youtube that someone was demonstrating a metal detector which uses a mobile phone as a main unit, a customized coil and an app.

It is a startup project and they aren't any units available for testing yet. (Link below)



I'd like those who have the knowledge and hands-on experience with electronic to tell me how is this going to work, considering the fact that smartphones can not send electromagnetic signals via headphone jack!
Thanks.

It's a cool idea! I don't know enough about electronics to understand all of that. But... the coil is where the electromagnetic signal is from...The phone and app are just analyzing the info. and translating it into something. I would imagine there is a lot more tech in a phone than most detectors? ....Who knows..I sure don't, I'm just guessing at things I have not much a clue about. There biggest work is probably the app?

Yes, the app seems to be pretty unique.

detectors transmit, and recieve
no idea how they are going send a pulse, receiving seems doable with a smartphone
interesting indeed

edit: AKYOR is using an external USB battery pack to power a booster in the coil, nice

Hopefully, whatever drawbacks there are to using a smartphone (lag in communication b/w phone and coil, etc.) might be overcome by the relatively massive computing power of the phone.

Check out Air Detectors they are currently on Kick starter

I assume it is just using the smartphone as a display and all of the electronics are in the coil & shaft.

Not going to open the video to see. ;-)

comparing the 2, the AKYOR (top) seems to provide more info (better sales pitch anyway)

Xenon

edit: hmmm, build that coil into a jacket (back) and that could be an excellent surreptitious wall checker

 

[Toecutter]

The AKYOR doesnt have its own battery, could be a good thing, but doesnt seem like the run time will be nearly as long....
I do like the appearance of the software more on the Air from what iv seen any ways...

Heck of a tone on that thing. Sounds like somebody prying a nail out of a board.

the AKYOR video shows an (optional ?) USB battery pack good for 100 hours (med sized)

...

edit: yea, that sound - got to dig it to get rid of the noise

 

[A2coins]

No thanks

 

[Toecutter]

Also no wires on the Air Detector...
Akyor just looks janky, the examples of software looks cartoonish and that rod.....lol....

They are on the right track with technology. From what i saw in the video along with other videos, they have a ways to go with development. The signal delay or latency or whatever you call it is way too much!

Interesting machine...

They use the phone to generate the signal but as far as I know the phone only generates audio signal!
The question here is, how they convert the audio to electromagnetic signals?

Through Alien technology? Those guys fly all over the galaxy! I'm thinking...They sold some of that tech to these guys. .....That's all I got!

This explains everything I don't understand. It's either Aliens or bigfoot...One of the two, or both since they have a working relationship with the Lizard race. And since ET couldn't phone home easily they had to give us cell phones. Next....They will show us how to travel through space and time with the same phones!!! One step at a time though....

 

[mrwilburino]

It's likely that all of the electronics are in the coil, so it transmits and receives the electromagnetic field, evaluates it, and sends that information on to the cell phone for the conversion to audio.

Hmm, similar to radio station!

Doesn't the Deus work in the same manner?...
