Once haunted by a dog that chased and bit him, the male student created an extremely effective dog repelling device 3
Coming from a childhood haunted by being chased and bitten by dogs, Nguyen Tan Minh was very worried and scared every time he approached dogs.
The dog repellent device called D.S Dog Security works by collecting the sound of a dog barking, then identifying and analyzing it.
The main purpose of the above product is to protect children from ferocious dogs.
The product was tested by Nguyen Tan Minh on a flock of 11 dogs (including both domestic and foreign dogs) in a family in Bac Ninh.
In 10th grade, Minh’s best friend, Nguyen Phu Si, often complained about the big dog at home that often barked and attacked strangers without any way to `punish him`.
But when he started researching the product, Si left to study abroad in the US, so completing the product was left to Minh.
In addition, the device will have additional GPS navigation features to support users when in danger, install a flashlight when traveling in the dark, and add SOS emergency calling technology.
Are you impressed with the achievements of these two guys?
