I’m very passionate about drones. So i decided to make one. i started collecting money as the accessories are expensive. at the end i purchased the minimum components needed to fly and didn’t purchased the RF remote for controlling then drone. instead of that i made a NRF24L01+Arduino remote and receiver for the drone.
I assembled everything and tested it inside my house, it was flying good and i was able to control it. one day i went out to fly it in open and time was around 10 PM, yes it was night. i went with my friend in a big park, and park was in front of Police Station, perfect place to fly in a country where drones have a complete BAN and that too in almost mid night.
Anyways i started flying the drone and keeping low at below 4-5 feet altitude. then my friend mocked to fly it high and then it was at 150 feet of altitude with no GPS installed, No battery monitoring, No Fail safe, all safety measures was disabled and that’s because i didn’t know about them.
The drone was hard to control as there was winds at that height. so it was moving away from me. winds causes the drone to climb more height and it lost the signals. now it was out of control at 180-200 feet height in dark night with no controls. but luckily i implemented a radio fail safe function in my arduino nrf Rx. which was able to land it in less the 2 min. but in 2 minutes it was away from me and landed or i should say crashed on roof of a hospital nearby.
Even after that it was able to fly, but now i never gonna fly it in such areas. I was a lesson to me to take every possible safety measures and keep this kind of dangerous things away from populated areas.
