How to build a UAV

This article will describe how to build a UAV. An Unmanned Arial Vehicle, or UAV for short, are advanced robotic controlled planes that carry surveillance equipment and/or weapons. They are used by the military, homeland security, and even by firefighters to help combat fires. This article will give insight into how to build a UAV.

Instructions

1. There is a great deal of work in building a UAV. It must be lightweight yet have sufficient power to stay in the air for long periods of time. First, you will need to design the body of the UAV, but to do this, you must estimate all the components that will be included in the UAV. Aerospace engineers can design the body to be aerodynamic, have a large wing span, and still have room for all the needed technology inside.

2. Next the shape and design of the body will be translated into components, and molds will be machined. These molds will take layers of carbon fiber and epoxy resin that will be cured in a high pressure oven called an autoclave. The components will then be assembled with adhesives and fasteners creating a lightweight composite body.

3. Next, the body of the UAV will be filled with a power source, a motor, a propeller to provide thrust, and all the necessary controls. Communication equipment is need as well, so that the UAV can be controlled by someone on land.

4. Once all the components are installed and tested, the UAV is complete. It is now time for it to take flight, preferable in the desert where crashing will not injure anyone.

Tips & Warning

  • UAVs are extremely expensive, so save up.
  • Some UAVs are bigger then passenger airplanes, so have plenty of room.
  • If you are successful in building a UAV, be sure to check with the government before selling them, as they may be illegal to sell.

Fingerprint Time Attendance – An Innovative Yet Efficient Invention in the Field of Biometrics

Everyday it might sound new while talking about major biometric products but biometrics is amongst us since long. We utilize the biometric products in our daily life by some or the other way just to get all sorts of benefits that each and every device is specialized on. While all this devices are based on the same technological process but they vary by the medium which acts as the source to offer the security. Some biometric devices are based on recognizing the iris of the individuals, some are based on recognizing the voice, and if some are based on recognizing the face then some are based on recognizing the fingerprint. While comes the involvement of the fingerprint, things become interesting isn’t it!

While considering the fingerprint as the source of security, curiosity automatically generates regarding the technology. Well, if you are curious to know about the technology then you are surely stepping towards the most useful and interesting concept in the world of biometrics. Biometric fingerprint reader of India is based on the touch technology. With this, every person needs to touch the device in order to get authenticated. Digging the core, the device captures the fingerprint details of the individuals and stores the data electronically. When the person re-visits the premise and punches the device again then, the device matches the stored patterns of fingerprint with newest patterns. When the device gets the match, it grants the authentication else it denies.

Unbeatable Truth regarding Fingerprint Time Attendance System:

Let’s take an example regarding the biometric fingerprint time attendance system. Just think once that you have installed a biometric fingerprint time attendance system in the place of face recognition system or any other biometric products. The biometric fingerprint reader in India is efficient to manage a huge mass and then too it requires a very little installation cost.

In spite of managing large volume of data, still it requires a minimum maintenance cost where as if you will install a face recognition system at your premise then, installation charge would be equal to the 1 year maintenance cost of the fingerprint device. Tough to decide, isn’t it! But when you are getting efficient system at a lower price and that is even, easily manageable and maintained then why not to go for it! Yes, your biometric fingerprint reader is much more capable and efficient than the existing other biometric products.

Reasons that makes it Stronger to Compete:

A biometric fingerprint device possesses a number of advantages in real life, which is not only beneficial for the organization but also for the entrepreneurs. Those positive points can be stated as follows:

* The device needs a very minimum installation cost.

* The device can work at a very fast rate and can manage huge bulk of data.

* Biometric fingerprint time attendance system can be maintained at a very low cost.

These are the benefits, which are making the biometric time attendance system user friendly. The device can be installed in indoor premises and can be utilized for 24×7. If you want your premise to provide you with better facility by maintaining the quality then, fingerprint devices are the right choice for your organization.
