According to The Verge, a user named rctest flight on You Tube recently brought a camera artifact that is very suitable for night use for drone enthusiasts - a Freefly Alta eight-axis aircraft with an assembly power of up to 1000. Tile LED light source.
As you can see from the video, in the dark night, wherever the drone goes, it is like a white. Scenes such as metal frame bridges and abandoned factory buildings in the dark are very clear when the drone is illuminated.
However, although the scenery in the lens is very exciting, due to the heavy equipment and mechanical parts, the sound is particularly noisy. In the video, the buzzing sound is like a million angry bees.
In response, some netizens said that in order to take a good-looking photo, it’s okay to endure it.
It is understood that this is not the first time rctest flight has challenged the "night" attempt. As early as last year, the user showed himself on "Youtube" the "best light flashlight in the world".
This flashlight is different from conventional. It is made up of 10 100-watt LED chips. Each chip is equipped with a large aluminum heat sink and is battery-powered. The "flashlight" weighs 4.5kg and can be used for 10 minutes after connecting the battery. According to rctest flight, it turns the night into daylight.
According to the working frequency response ranges, speakers can be classified into tweeters, mid ranges, woofers and full ranges.
