Ghost (EMF) detector

If you think that ghost communicate with us through electromagnetic fields, you might be interested in the following:



It seems that I have a ghost in my alarm clock...

Note: I used a 10M resistor for more sensitivity

Source code:
Code: Select all
#include <SPI.h>
#include <Gamebuino.h>
Gamebuino gb;

int input, prevInput, inputVar;

void setup(){
  gb.begin();
  gb.titleScreen(F("Ghost detector\nRequires EMF module\nAnd I2C pullup disabled"));
  gb.setFrameRate(100);
}


void loop(){
  if(gb.update()){
    input = analogRead(A5);
    inputVar = prevInput - input;
    prevInput = input;
    gb.display.fillRect(0,40,constrain(abs(inputVar), 0, 84), 8);
    if(inputVar > 10)
      gb.sound.playTick();
  }

Wait, all that hardware can only mean one thing... DO YOU LIVE IN AMERICA? Well, if not(most likely, because I think you live in France...), I'm just saying that if you sell them at stores, you get more money... which leads to more gamebuino + rich Rodot + gamebuino becomes more popular = ok, we got to agree with this... it just equals rich Rodot. Just my idea, if not... try to kickstart it in France then make it popular in USA and CA. Then sell the accessories in the stores. What do you think, oh that must be a nasty ghost. They sit in your alarm clock then reset it!!!! :lol: :lol: :lol:

The console itself sold VERY well on it's indiegogo campaign (he ended up selling close to a thousand of them. Many of them, like mine, are heading to the states)

An EMF plugin would be a fun addon to to make games for. Make a game called 'Ghost hunter' It requires that you have the EMF detector, and an I2C microphone (edit: and a hauted house). You're score is based on how many times you don't scream like a little girl XD

Mmmm! Care to share your sketch for this? With the nice geiger counter ticking and the intensity bar?
I have a magnetic implant in my finger so I can feel EMF, and this would be awesome to make visible to curious people where all the things are that I can feel.

No problem, I just updated the first post with schematics and source code.
What you you mean a magnetic implant? What's its purpose? Sounds great, I want one!

Thank you!
I went to the piercing studio and had them implant a neodymium magnet into my finger. I can feel electromagnetic fields as vibrations, it's like a sixth sense :)
Here's a little demonstration:

and I've also recently made a coil, attached it to a bluetooth speaker's amp and turned my finger into a speaker :D

hi,
you can add a program to communicate with the invisible world with such a project?
I'm curious!
