How to choose a DV camera recorder

With the vigorous development of the digital video camera market, manufacturers continue to introduce new products, product features more and more powerful. Facing a wide range of digital cameras and a variety of technical parameters, it is inevitable that some consumers might feel confused if they are not very proficient in this area. In fact, for any digital video camera, the imaging quality is everyone's concern, then the imaging quality has a direct impact on the sensor and the lens. The use of liquid crystal display and the use of media storage are also the two more crucial issues. So, as long as the attention of the following four points, you can choose to a more satisfactory DV Digital Camera.

Sensor and pixel

In the past, the digital camera image sensor is a single CCD or 3CCD, such as Panasonic, there are many 3CCD products. But in 2005, Sony Handycam took the lead in installing the CMOS sensor on the tape DV-DCR-PC1000E. The CMOS sensor appeared on the digital video camera, which is the requirement of the digital video camera to enter the HD era. It has accelerated the popularization of HD cameras and HD cameras process. Currently the mainstream products have reached megapixels level, basically, you have no need to choose the one under 3 megapixels.

Lens and zoom

The quality of the lens also has an impact on the digital camera imaging, an excellent lens is the image quality assurance. As we all know, the German imaging quality of the optical lens is world-renowned, Sony and Carl Zeiss have many years of cooperation history, a variety of Sony digital cameras have used the famous Carl Zeiss Vario-Sonnar T * lens, which laid a solid foundation for the Sony digital camera image quality. In addition, Panasonic and Lycra also have cooperation. The digital camera lens has a zoom function, the more common use is the 10x optical zoom lens, like the Mini DV Camera.

Novice models

Technology is developing every day and some digital camera recorder have more and more features. The Mini VR Sports Camera has two 220 degrees panoramic lens make the view complete and can record 360 degrees video without missing any details. Video in 2 lenses is seamlessly stitched. With VR shooting mode, this Mini VR Camera allows you have a virtual reality experience. It also supports sharing moments to your social network, WiFi connection, smartphone connecting to iOS and Android.

How to prevent your children from getting worse eyesight

Currently, myopia has become the primary reason for decreased vision in adolescents. The incidence of adolescent myopia increased year by year, while the age was getting younger year by year. Prevention and control of juvenile myopia have become an important global public health problem. Recently, an Australian scholar published a report saying that the prevalence of global myopia in 2000 was 22.9%. It is estimated that by 2050, myopia will comprise 49.8% of the global population. In other words, about half of the world's population will be myopic in 2050. This important data finding warns us that we should pay more attention to young people's vision problems and prevent vision loss as soon as possible.

No one wants to have poor eyesight since childhood and have to wear a glasses all the times. However, nowadays, children are addicted to computer games or mobile phones which will hurt their eyes. If your children also love to watch computer or mobile phone, these things might be helpful.

Make your own Arduino Board- DIY instructions for Beginners (part 2)

When you get your Arduino control panel, you first thing you need to do is to install the driver on your computer so that you can experiment with it. All kinds of practical operations and experiments should base on this. This will require you download the Arduino IDE to your computer (the IDE is Arduino's software development environment, whether Mac, Windows, or Linux). If you can not find the download address, you can comment below and I will offer you some guidance. Then, you need to purchase some Expansion Boards online, for rc drone controller, you might need the bluetooth module and the GPS module, for example.

Steps to prepare an Arduino Board:

1. Socket attachment

The first step would fix the socket seeing that it is fixed to the notch of the perf board. You can drill and create a larger notch on the board. You could also get an Amplifier Board or ICD Controller board. The Bluetooth power amplifier board is suitable for all small bluetooth speakers. The lcd controller board is compatible with Notebook, host computer, monitor, VGA, host DVI, Xbox/PS3/PS4, raspberry pie signal interface and so on.

2. Add a 5V and 3.3V Regulators

By holding the 7805 printed side down fix the 5 V and 3.3 V regulators using the decoupling capacitors. The 3.3V do not have the same pins as in 7805; hence make sure to keep the print sides towards you.

3. Indicator LED

Connect the LED to the output of 7805 regulators to indicate the power. Connect the anode to 150-ohm resistor and connect the resistor to the output of 7805. Plug in and make sure everything is fine.

4. Connect the power and ground pins

Connect the pins 7, 20 and of 5 volts; 8 and 22 to ground.

5. Reset Button

Take a pin to connect to 10k and then to 5v continuously connecting to the bush button to pin 1 along with other to ground.

6. Add on crystal oscillator

Connect 16 MHz oscillators to pins 9 and 10. After this connect the 22cp to pin 9 with other ends to ground. Repeat with pin 10.

7. LED on Pin 13

Connect red to pin 19 and cathode to 150-ohm resistor.

8. Female Headers

Label them all to avoid confusion and connect them to respective pins and make sure to be tedious.

9. Other headers

Connect the 6 male headers opposite to the power jack as given.

10. Use an Arduino Uno to program

You just need to prier the chip to Arduino board while off and you can replace the chip.

Make your own Arduino Board- DIY instructions for Beginners (part 1)

Many people are interested in an Arduino box and doing exciting stuff with it. Some of you might be interested in preparing an Arduino board yourself. Well here are some DIY instructions for you so that you can work and create your own system. Some starter readers may wonder what the differences between Arduino Boards and Arduino Shields and what their respective uses are. In short, arduino board is the master chip, and the shield is an extended board. The former is responsible for the operation, and the latter is for some special functions. For example, the role of the music shield is to provide the function of playing music. There are other Expansion Boards that we will talk about in the following paragraph.

The cost of all the arduino starter kit is very less and easily available in the market. You can find all kinds of the arduino starter kits on the online store which are quite affordable and can basically meet all your entry demands with so many different parts and components to choose. There is no requirement of a board; you just need an Atmega chip as a main piece for the project unless you are interested in Arduino Nano (the arduino nano can be said as a prebuilt board). It is easy if you need to add more boards to your existing Arduino board. The serial connected to USB adapter chip can help the microcontroller to interface and connect to your computer. Let’s see how the process can be completed easily! Here is just an example of a basic starter arduino kit that I randomly found online, and you can choose whichever you like.
