Turn Your Dr.Duino Into A Ghost Detector??? GASP!

Just in time for all hallows eve, I am releasing my goulish Dr.Duino ghost detecting circuit and code!

Built with your trusty Dr.Duino! (You don't need a Dr.Duino but sure makes this easy!)

Ghost detecting circuits work on the "theory" that ghosts impose a change in electromagnetic frequencies as they approach.

If you have ever watched those ghost hunting shows, they carry around something they call the K2.

An electromagnetic detector tuned for ghosts!This is one of their staples!

Here is what it looks like

 

I thought it might be fun to turn your Dr.Duino into your very own ghost hunting device!

Here is what you need!

1) Your trusty Dr.Duino and Arduino Uno board

2) 1M to 10M Ohm resistor. You will need to play with this value to get the sensitivity you want.

3) A long piece of wire.

 

Wiring

1) Wire it just like the picture below and make sure your buzzer, and all LED's on the other side of the Dr.Duino board are set to pass the signal out to the Dr.Duino board. Refer to your Manual for jumper positions.

I just took a 1 M ohm resistor, wrapped a long piece of wire around it and plugged it into A5 on the Dr.Duino.

The other side is plugged into ground.

NOTE* Make sure the jumper for A5 input is set to pass the signal from the resistor to the Arduino or you will be reading the on board potentiometer and not your ghosts.

 

 That's it!

Now just open a new sketch in your Arduino IDE, and upload the following code.

Don't worry, you can get it here!

What will it do?

Upon upload it, you will see that the LED's on the Dr.Duino board will begin to flash in accordance with increasing EMF. Static also works... rub your feet on the floor to develop a charge while touching the wire. You'll see what I mean.

Once you get into the Ghost zone, the buzzer will beep to let you know you have a ghost on your tail!

I wrote the code so you can tinker with the values.

Ps-While you don't need a Dr.Duino to make this work, it sure does make your life a whole lot easier!

ENJOY!

  • Do you have any video showing one in use????

    Thanks!! :-)
