Drones

The Mavic 2 Pro just came out and people are euphoric about the drone because of its one inch sensor, it’s ability to zoom and it’s omnidirectional systems keeping an eye on the environment below, behind, above and ahead of it. It also has a flying time of 31 minutes. 

I’m happy with the DJI Spark. Last Autumn as the nights shortened and work got in the way of flying the drone I felt disappointed that I would have to suspend the passion whilst waiting for the next summer to arrive. This summer came and it is now approaching an end and I haven’t flown as much as I would have expected to. It’s partially due to having to get the charger out, charge all the batteries and fly somewhere new that slowed me down. NFZs limit the number of places where you can fly. 

Trying various drones

This year I finally bought a few drones to play with and DJI and Hubsan are currently my favourite brands. The most fun to fly indoors is the Hubsan Nano Q111 drone, or something to that effect. At first this is a hard and temperamental little drone to fly. Just getting it off the ground is a challenge., This challenge comes from the fact that it has no pilot assistance. It slews to the right and the left and it has no altitude hold. This means that constant little inputs are needed. As the battery depletes you need to give the drone more power simply to hover. With practice the drone is really fun and best of all I didn’t break any props. I only burned out two of the motors when the drone got caught in something. I tried flying the Q4 as well but the results were disappointing. I tried flying the Demon something by some brand and this was a flop. The problem with this drone is that the props are well protected against colliding with things but the struts are too fragile. Within just a flight or two I broke the strut to one of the props and it is now great at spinning in place rather than flying.

In the age of drones this is how shark reporting should be done. The Coast guard or local surfing schools should fly a drone around and check to see whether there are any sharks present. If and when they spot a shark or groups of sharks they could temporarily close the beach until the threat is gone. It reduces the need for shark nets. It also reduces the need and desire to kill any shark that is spotted as people are informed ahead of this time. The report tells us that the sharks in the video are juveniles and that the reason for which they are on this section of beach might be linked to a dead whale floating “about eight miles away in that direction”. There is no sensationalism. We are given the facts. The report then tells people that if they do want to swim or surf and be safe they should stay near the lifeguard tower. When a whale dies it provides sharks with enough food for days or even weeks. It provides them with food until it looses buoyancy and sinks to the bottom of the sea where crabs and eels eat the remains. I’m sharing the second video because we see divers photographing and filming sharks as they eat a whale carcass. We see how close they get without any difficulties. There are a number of interesting documentaries to learn more about sharks and I recommend watching Sharkwater because it shows that rather than sharks being a threat to us it is us that are a threat to sharks. By taking a calm and rational approach to sharks we are helping preserve the ecosystem. By learning to cohabit with these animals we are allowing future generations a chance to see these animals. With today’s technology we can monitor risk, especially on calm and clear days.

K2 with a Drone is a documentary following Petr Jan Juracka, a scientific photographer’s trip to K2 with Klara Kolouchova with two drones. He performed extensive testing before setting off on the trip. He flew the drone in a hyperbaric chamber to see how it would react. He flew it in freezing conditions to check that the batteries would cope and then he flew in other places. He had already flown his drone in a multitude of countries and Pakistan was the latest challenge. We see the journey to base camp. We see images of the snow and ice, of rivers, of challenging roads and more. The documentary mixes fixed camera footage and drone footage in a pleasant to watch manner.
