French schoolchildren have collected a cheap analog of virtual reality glasses. With the support of the computer science teacher, they ordered all the necessary details via the Internet and started assembling. In a case printed on a 3D printer, they inserted a three-axis gyro MPU-6050 and a single-board computer Arduino Due. The total cost was only $ 100, which is much less than the cost of original virtual reality glasses. The guys denied the words of the developer of the most famous virtual reality helmet of Palmer Lucky, who stated that such a device can not be assembled at home.
