Usually we think that drones are just expensive toys for aerial photography enthusiasts, but they also have a great role in business and research and development. For example, drones can be mapped, delivered, rescued, etc., but for some small businesses or research institutions, they can't afford the expensive price of professional drones. As a result, a development team in Italy launched a Tsubasa V3 open source drone designed to help some researchers use professional-grade mapping drones at a lower price. The fixed-wing drone features a weight of only 250 grams, but integrates 2.4GHz wireless network, GPS module, telemetry module, solar panel, built-in lithium battery and other components, very comprehensive. The reason why the drone weight is controlled at 250 grams is that it is better able to perform the surveying work, but also for longer flight time. Basically, the Tsubasa V3 can achieve a flight speed of 10 m / s, and the endurance is 15 minutes. This endurance is enough to achieve a certain area of ​​mapping. Of course, the development team is still trying to integrate more solar panels to extend their endurance. Tsubasa V3's ability to paint and measure is impressive, and it can be used to achieve more detailed geomorphological surveys, which is of great help to some research teams. Tsubasa V3 is an open source product that offers a DIY digital package of 99 euros (approximately RMB 716). Users can obtain CAD drawings and instructions and use their own 3D printer to make their own drones. Of course, the development team also provided the finished product, but the price is relatively expensive, it needs to pay 1,650 euros (about 12,000 yuan), and the delivery time is from March to April next year. An electromagnetic interference shield sleeve is a protective layer used to shield electronic components from electromagnetic interference (EMI). Mainly tinned copper, copper core and other materials can be selected, widely used in electronics, aircraft, ships, industry and fuel vehicles and new energy vehicles wiring harness system shielding and safety protection. Compared with tinned copper, copper core material also has the function of electromagnetic signal shielding, and is more lightweight, better softness, customers can choose different materials according to their own needs. If it is applied to the automobile, the soft connection tinned copper strip is also a suitable choice. The soft connection tinned copper strip is made of polyester composite wire and polyester monofilm, which is spun by the weft and yarn spinning machine. It meets the environmental protection certification such as RoHS, REACH, halogen free, etc. It is soft, lightweight, and has the function of excellent wear resistance, noise reduction and finishing.
