Night vision device from old camera
Human vision is an amazing thing. The eyes are called the mirror of the soul and the mighty instrument with which nature has endowed us. That's what we really do not have, it's to see in the dark, as opposed to technical devices called NVNs or night vision devices. Until recently, we've heard of them as special weapons for the military, who use them for covert surveillance and maintenance fighting in the dark. The capabilities of such devices are used in modern conventional cameras. However, some of them are able to distinguish objects in the infrared spectrum, while others are not. Today we will show how to make a night vision device from an ordinary digital camera. So, let's get started!
The principle of work and resources for homemade PNVFor the basis of our PNV is a digital camera, nicknamed in the people "soap box".The electronic stuffing is saved, because it is able to transmit the image in real time through the LCD screen. By changing the filtering of the lens and increasing the sensitivity of the camera to the infrared range, as well as providing the camera body with infrared illumination, we discover new possibilities of a digital camera capable of capturing objects in the near infrared range. Also, such a device can also be used as a thermal imager, distinguishing heated objects, for example, an iron, electric stove or kettle left unattended. Materials: Tools:
- Soldering iron;
- Screwdriver with interchangeable tips;
- Paint knife;
- Hot glue gun;
We manufacture a night vision device (NVD)For this experiment, the author purchased a working digital camera Samsung S1030.This is a regular soap dish with a sensitivity of 50 - 1600 ISO, a maximum resolution of 3648 x 2736, equipped with a 2.70-inch LCD screen on the rear panel.
Dismantling the infrared filterUnscrew all visible screws from the back of the camera. It is easy to make a screwdriver, making sure that nothing prevents its dismantling. This should be done as carefully as possible without damaging the plastic closures and clips, as well as without pulling out the cables of the electronic filling. "style =" max- width: 100%; " alt="A night vision device from an old camera"> We open the LCD screen, carefully removing it from the frame of the holder, which is then also dismantled. Cables from the LCD screen and camera control release from the connectors. The output control board should release the front cover,which can now be detached from the device.
