A fierce man who made his own goggles with 10,000 yen appeared

Headset type night vision goggles generally cost more than about 50,000 yen, and it is not something that you can easily purchase saying that you want it, considering the frequency of use etc. So, "Thinking that using Raspberry Pi on a single board computer can be made cheaply?", A person who really did realize appeared in Reddit . According to this user, the construction cost is less than 100 dollars (about 11,000 yen).

This night vision goggle was created by Reddit as a user named mtnbikerdunn. Mr. mtnbikerdunn decided to remodel the existing headset to make his own goggles without taking time. Therefore, he said that he prepared an inexpensive headset which is often used when piloting while watching the image of the camera installed in the drone.

This headset was connectable to another terminal with the HDMI cable. So, mtnbikerdunn connects to Raspberry Pi Zero W. With this, the screen of Raspberry Pi is now displayed on the headset screen.

Then, mtnbikerdunn who connected Raspberry Pi and the infrared camera module built a package that fixes 'headset', 'Raspberry Pi Zero W', 'infrared camera module', and integrated it. Inexpensive night vision goggles were completed.

The image when actually using the room darkened and used is below, you can see that a clear view can be secured even in the dark. Also, since the resolution was 720p, "It's a good image quality," Mr. mtnbikerdunn says.

According to Mr. mtnbikerdunn, "Raspberry Pi processed the image captured by the camera, and then the image was projected on the headset, so the video lag against the actual movement was terrible." So, he succeeded in minimizing the lag by deleting all unnecessary functions of the OS " Raspbian stretch Lite" installed in Raspberry Pi Zero W. "The effect of the optimization of this OS has lost useless processing and the continuous use time has also increased," Mr. mtnbikerdunn says, and he says that if the battery is fully charged, it can be used for about 3 hours in a row.
