With the wide spread of drones and their uses in many fields, the payload release mechanism has become one of the most important additions that let you take your drone to the next level. This mechanism is based essentially on a small servo motor. Even though this servo motor costs only one to a few dollars depending on specifications, these devices are still pricy, $100 to $200 or even more, except for small individual businesses we find time to time on amazon and ebay which sell their devices under $100 but not less than $50 in many cases. In this course, I will teach you step-by-step how to build a drone payload release system for about $2.This course will also give you a simple idea on how to build a small individual business based on this device. This course discusses how to build a payload release system in three possible scenarios:1-The first scenario, which is the simplest - Drone that has a pin for tilt Gimbal socket- or any other pin (Signal - Positive - Negative, 3 to 7 volts) controlled by the transmitter.2-The second scenario: drone with controlled light during flight (most drones).3- The third scenario is the same as the second scenario, drone with controlled light during flight, but in this scenario, I talk about how to build a ready-to-ship device for those who want to make business through this device. because my main goal is to help you build a drone payload release system, which is easy in the first and second scenarios, but not complicated in the third scenario, which needs an electronic circuit. Although this circuit is simple, and I can do it for you in different ways, but when it comes to business and production, its better to work on a good and strong design, and test it several times before production, because the slightest error will lead to bad reviews and low ratings, which lead to the failure of the idea from the beginningEven though, I made a simple circuit just for demonstration, using only a PNP transistor and a diode in addition to LDR and battery. This course also contains a full guide (PDF file) on how to avoid a drone crashing or falling into the sea while used in fishing, based on about 4 years of experience and more than 300 flights without any crashes.
