Professional night vision devices are expensive and usually not stereoscopic. They cannot be worn like glasses. A home-made device, moreover, stereoscopic, can be made from two unnecessary mobile phones.
Instructions
Step 1
Take two identical unnecessary but functional mobile phones equipped with cameras.
Step 2
Remove the lenses from your old glasses. Install two identical magnifiers instead.
Step 3
Make two brackets from a children's metal construction set. Attach them to the glasses so that they point forward. Come up with a way of attaching phones to them (depending on their design).
Step 4
Put on your glasses. Experimentally find the distance at which the phone screens are clearly visible. Make marks on the brackets. Take off your glasses and secure the phones at an appropriate distance from the lenses with their glasses facing the lenses.
Step 5
Check if the phones allow you to enter camera mode without a SIM card. If not, insert cards into them. Remember that they are blocked if you do not use any paid service for six months.
Step 6
Take an LED flashlight that uses 5mm diodes. Solder white diodes out of it (those that will not fail during desoldering, use them later in a homemade flashlight). Solder, respecting polarity, infrared instead. Perform all soldering with the flashlight off.
Step 7
Find the item in the phone menu that allows you to cancel the automatic backlight off. Then, regardless of whether you managed to find such an item, make the brightness of the backlight minimum, since you will still have to use the device in the dark.
Step 8
Put glasses on your head. Turn off the lights in the room. Illuminate it with invisible infrared light from a flashlight. In both phones, enable camera mode. You will see objects illuminated by a lantern, however, their image will be white, not green, as in a factory device. If you did not succeed in making the backlighting of the phone screens permanent, periodically press a key on them that does not switch camera modes (it is selected empirically, depending on the phone models).
