One day, I was thinking about taking some pictures with my friends in school. But its not possible as i would get caught from sound from a cameras. If i bring a mobile, Its very hard too take a photo with it as i would get caught due to its size. So i thought why not build our own camera which is small,Portable and could take photos without being caught. I had a esp32 cam in my home so i used it as the mcu and camera.
Its a camera where you can take photos without sound and getting caught. It could even send the photo to your telegram account and it is powered by a battery. A photo can be taken by touching a button in the touch screen. It may sound like a joke but its not.
