​​Funny owl Ulo — smart device for playing, communicating and tracking
Compact (with a tennis ball) security camera is made in the form of a funny owl that blinks and rotates its eyes, but at the same time performs many useful functions. The device, which must be connected to Wi-Fi, provides communication through the owl's eyes, which are mounted cameras. Actually, the main camera is located behind the transparent beak of an owl. Its surface is mirrored – in fact, the beak is a collecting lens that expands the camera's viewing angle. Just below is a microphone; the Ulo also has built – in orientation and motion sensors, a Wi-Fi module, and a lithium-polymer battery that can be charged from a USB port or household power supply.

AREOMETER

Concentration and density data are in constant demand. The strength of alcoholic beverages, the quality of acid in a battery, the condition of antifreeze, saline solutions, and the content of soluble substances in juice are just a few of the tasks where areometers are indispensable.
