Let’s look at some of the most common types of ghost-hunting equipment and their roles in a paranormal investigation.

EMF Meters

Electromagnetic Field (EMF) meters are among the most essential tools in a ghost hunter’s arsenal. These devices measure fluctuations in electromagnetic fields, which some believe are a sign of paranormal activity. 

The theory is that ghosts and other entities can manipulate these fields, causing noticeable spikes on the meter. EMF meters can detect these changes, providing investigators with potential evidence of a spectral presence.

EVP Recorders

Electronic Voice Phenomena (EVP) recorders are used to capture sounds and voices that are not audible to the human ear. These devices can pick up frequencies beyond our hearing range, often resulting in recordings of unexplained voices or sounds. 

Many ghost hunters use EVP recorders to communicate with entities, asking questions and waiting for a response that can be analyzed later.

Infrared Cameras

Infrared cameras capture images and videos in low light or complete darkness, conditions often associated with ghost-hunting. 

These cameras can detect infrared light, which is not visible to the naked eye, allowing investigators to see potential paranormal activity that would otherwise go unnoticed.

Laser Grids

Laser grid pens project a grid of dots onto a surface, creating a field of light that can help detect movement. If an entity moves within the grid, the dots will be disturbed, providing visual evidence of the activity. 

This tool is handy in detecting shadow figures or other subtle visual anomalies.


Paranormal entities are often associated with sudden temperature drops. Thermometers, particularly infrared thermometers that can take spot readings, are used to detect these paranormal cold spots as potential signs of a ghostly presence.

Spirit Boxes

Spirit boxes, also known as ghost boxes or Frank’s boxes, rapidly scan through radio frequencies. The theory is that spirits can manipulate this white noise to form words or sentences, allowing for real-time communication with the other side.

2) Assembly

The assembly process involves connecting the sensor to the Arduino using the jumper wires. 

Here’s how to do it:

  1. Connect the VCC pin on the sensor to the 5V pin on the Arduino: This provides power to the sensor.
  2. Connect the GND (ground) pin on the sensor to the GND pin on the Arduino: This completes the circuit, allowing electricity to flow.
  3. Connect the SDA (data) pin on the sensor to the A4 pin on the Arduino: This allows the sensor to send data to the Arduino.
  4. Connect the SCL (clock) pin on the sensor to the A5 pin on the Arduino: This controls the data transmission timing.

3) Programming

Once the assembly is complete, you’ll need to program the Arduino to read the data from the sensor and light up the LED when the magnetic field strength exceeds a certain threshold. 

Here’s a basic outline of how to do this:

  1. Install the Arduino Software: You’ll need the Arduino IDE (Integrated Development Environment) to write and upload the code to your Arduino. You can download it for free from the Arduino website.
  2. Write the Code: The code needs to do three things: initialize the sensor, read the data from the sensor, and turn on the LED if the magnetic field strength is above a certain level. Many tutorials and code examples are available online to help with this step.
  3. Upload the Code: Once you’ve written the code, you’ll need to upload it to the Arduino. Connect the Arduino to your computer using a USB cable, select the correct board and port in the Arduino IDE, and click the “Upload” button.

4) Testing

Once everything is assembled and programmed, you can test your DIY EMF meter. 

When you bring a magnet close to the sensor, the LED should light up. This is because the magnet creates a strong magnetic field, which the sensor detects and sends a signal to the Arduino to light up the LED.

Remember, safety should always be your first priority when working with electronics. 

Always double-check your connections before powering up the circuit, and never touch the circuit while it’s powered. With patience and practice, you’ll have your own DIY EMF meter in no time.

How to Convert a Regular Camera into an Infrared Camera for Ghost-Hunting

Infrared photography can open up a whole new world of imaging, revealing invisible things to the naked eye. 

It’s handy in ghost-hunting, where it can help capture images in low light or complete darkness. However, infrared cameras can be costly. 

Fortunately, with a bit of patience and technical know-how, you can convert a regular digital camera into an infrared one. Here’s a more detailed guide on how to do it.

1) Materials

Before you start, make sure you have the following materials:

  1. A digital camera: Any digital camera with a removable lens should work. However, an older model is recommended as you won’t risk damaging your primary camera. You can also purchase a cheap digital camera and start from there.
  2. A screwdriver set: You’ll need this to disassemble and reassemble the camera.
  3. An infrared (IR) filter: This can be purchased online. Make sure to get the right size for your camera’s sensor.
  4. A clean, well-lit workspace: You’ll be dealing with small, delicate parts, so it’s essential to have a clean, well-lit area.

2) Disassembly

The first step is to carefully disassemble the camera. This process will vary depending on the camera model, so looking up a guide specific to your camera may be helpful. 

Generally, you’ll start by removing the outer casing, the lens, and the sensor assembly. Be sure to keep track of all screws and parts, and handle everything carefully to avoid damage.

3) Removal of the IR Block Filter

Most digital cameras have an IR block filter over the sensor to prevent infrared light from affecting regular photos. 

Once you’ve exposed the sensor, you’ll need to remove this filter. It’s usually a piece of glass or plastic that sits directly over the sensor. 

Be careful during this step, as the sensor is very delicate.

4) Installation of the Infrared Filter

After removing the IR block filter, you’ll install the infrared filter in its place. The filter should fit over the sensor. You may need to cut it down to size if it’s too big. If it’s too small, you can use a non-conductive material like plastic or paper to hold it in place.

5) Reassembly

Once the infrared filter is installed, you can reassemble the camera. This should be done in reverse order of disassembly. Be sure to replace all screws and parts in their original locations.

6) Testing

Now it’s time to test your converted camera. The camera should now be able to capture images in the infrared spectrum. 

A simple test involves photographing a TV remote while pressing a button. The camera should capture the infrared light emitted by the remote, which will appear as a bright light in the photo.

However, capturing the unseen world of infrared light can be a valuable tool in your ghost-hunting arsenal.

DIY EVP Recorder

Creating an Electronic Voice Phenomena (EVP) recorder is a fascinating project that can significantly enhance your ghost-hunting experiences. 

While most digital voice recorders can capture EVPs, there are ways to improve the quality and clarity of your recordings. 

Here’s an expanded guide on how to create and use an EVP recorder effectively:

1) Materials

To start, you’ll need a digital voice recorder. This doesn’t have to be an expensive model; even a basic one will do. However, look for a recorder with a high-quality microphone, a good signal-to-noise ratio, and the ability to transfer files to a computer for analysis.

Sony ICD-PX370 Mono Digital Voice Recorder with Built-In USB Voice RecorderAiworth 72GB Digital Voice Recorder Voice Activated Recorder, or the GStore 48GB Digital Voice Recorder are excellent choices.

Next, you’ll need an external microphone. This can help improve your recordings’ quality by reducing internal noise from the recorder itself. A directional microphone can be instrumental as it allows you to focus on sounds coming from a specific direction.

Finally, you’ll need audio editing software. Many free options are available, such as Audacity, which offers a range of tools for analyzing and enhancing your recordings.

2) Setting Up Your EVP Recorder

First, connect the external microphone to your recorder. Test it to ensure it works correctly and that the recorder picks up sound from the microphone. You may need to adjust the recorder’s input settings for the best results.

Next, set the recorder to the highest quality recording setting. This will use more memory but result in clearer, more detailed recordings that are easier to analyze.

3) Conducting an EVP Session

When conducting an EVP session, creating the right conditions is important. 

Choose a quiet location and eliminate as much background noise as possible. This includes turning off any unnecessary electronics that can create electromagnetic interference.

Start by introducing yourself and explaining your intentions. This can help to create a positive atmosphere and may encourage any entities present to communicate.

Ask clear and concise questions, leaving a gap of around 20 seconds after each question to allow potential responses to be captured. Speak in a normal tone of voice and avoid whispering, as this can be mistaken for an EVP during analysis.

DIY Laser Grid for Ghost-Hunting

A laser grid is an invaluable tool for ghost-hunting, providing a visual method for detecting movement and visual anomalies during an investigation. 

The concept is simple: a grid of light is projected onto a surface, and any grid disturbance could indicate paranormal activity. 

Here’s a more detailed guide on how to build and use a laser grid for ghost-hunting:

1) Materials

To create a laser grid, you’ll need the following items:

  1. Laser Pointer: A standard laser pointer will work, but consider using a green laser pointer for best results. The green light has a wavelength that is more easily detected by cameras, making it ideal for capturing potential evidence. My favorite green light laser pointer is, by far, IVVTRYI Green Laser Pointer Long Range High Power Tactical Green Beam.
  2. TripodA tripod will hold the laser pointer steady, ensuring a consistent grid pattern. Any stable, flat surface can work as a substitute if you don’t have a tripod.
  3. Cardboard: A piece of cardboard will create the grid pattern. The size of the cardboard will depend on the size of the grid you want to project.
  4. Craft Knife: A craft knife will be used to cut the grid pattern into the cardboard.

2) Creating the Grid

Creating the grid is a straightforward process, but it requires precision:

  1. Design: Draw a grid pattern on the cardboard using a ruler and a marker. The size of the squares will depend on your preference, but a 1-inch by 1-inch grid is a good starting point.
  2. Cutting: Using the craft knife, carefully cut out the squares to create the grid pattern. Remember to place a cutting mat or another protective layer under the cardboard to protect your work surface.
  3. Attachment: Attach the cardboard to the laser pointer. You can use rubber bands or tape to secure it. Ensure the laser shines through the grid pattern when turned on.

3) Setup

Setting up the laser grid involves finding the right location and positioning the laser pointer correctly:

  1. Location: Choose a location where you suspect paranormal activity. This could be a specific room or a particular area within a room.
  2. Positioning: Mount the laser pointer on the tripod and position it so the grid pattern is projected onto the area you want to observe. The distance between the laser pointer and the surface will affect the grid size. Experiment with different distances to find what works best for your investigation.

4) Observation

Observing the laser grid is where patience and attention to detail come into play:

  1. Monitoring: Watch the grid pattern for any disturbances. This could be a dot disappearing, a line wavering, or a general distortion in the grid.
  2. Recording: Consider recording the grid with a video camera. This allows you to review the footage later and also provides potential evidence of paranormal activity.
  3. Interpretation: Any disturbance in the grid should be noted but not immediately considered paranormal. Always look for rational explanations first, such as drafts, insects, or other natural causes.

Creating a laser grid for ghost-hunting can be a fun and rewarding DIY project. Not only does it provide a visual method for detecting potential paranormal activity, but it also allows you to engage with the investigation in a hands-on way.
