Because of this, Roy's apartment have only one single wall outlet, so Roy can only power one of his electrical appliances a T a time.Roy likes to watch TV as he works on his computer, and to listen to his HiFi system (on high volume) while he vacuums, so Using just

Today, I chose this plug-in for analysis and research.Bo Lian's SP2 (smart plug)Why is this socket widely used, and the smart energy provided by the component manufacturer marvell is also widely used in domestic entrepreneurial teams, it is reported that the Xiaomi outlet also uses the marvell solution.
Appearance, for example, is the main character of our research today.

the area that should not appear based on the light source direction of the gradient background, change the layer blending mode to the front pane, adjust the opacity, and then enhance the shadow effect. I used two layers to enhance the shadow effect. The operations are the same, but they only change the distance and opacity of the layer.Use a rectangle tool to draw a rectangle and adjust the anchor to make it a trapezoid. Let's make the bottom of the air outlet.Next, we will create a three-d

It determines the life of the faucet and the outlet effect. It is best to use the ceramic sp.Outlet filter: Generally, the outlet of the faucet is provided with a rectification network mask. A good faucet
power supply operating voltage range of 170v-240v, when the mains voltage below 170V, the computer will automatically restart or shutdown. Because of the fluctuation of the mains voltage we sometimes do not feel, so we will mistakenly think that the computer inexplicably automatic restart.
Solution: For regular power supply instability areas, we can purchase UPS power supply or 130-260v wide switching power supply to ensure the stability of the computer work.

This kind of situation, most will appear in the DIY machine, the host power supply line with the power cord has not been 3C certification, and the power outlet does not match. When we shake the table or touch the host will appear when the host automatically restart, usually accompanied by a slight electric spark "PA" sound.
Computer use of small common senseThe computer power light is not bright, the monitor also does not show!
Question: Make sure the power cord is connected properly and check that the power plug is securely plugged into the 220V power outlet on the wall. Also check the wall outlet for normal power supply, or use a different power outlet to try again. If the prob

1. Dip dual-row direct insert Encapsulation
Dip (dualin-line package) is an integrated circuit chip encapsulated in the form of Dual-row direct insertion. Most small-and medium-sized Integrated Circuits (IC) use this encapsulation form, generally, the number of pins cannot exceed 100. The CPU chip in dip package has two pins and needs to be inserted into the chip socket with dip structure. Of course, it can also be directly inserted into the circuit board with the same number of welding holes
provides a default implementation for an interface, so that the type can be extended from this default implementation without the need to extend from the original interface. As a special case of the adapter mode, the default adaptation mode has special applications in the Java language.
Problems
So that classes that cannot be combined because of interface incompatibility can work together.
Class adapter Mode
We use an example to learn the adapter mode: in daily life, the plug of the laptop is
280 ℃, the gas above this temperature must take cooling measures, the gas below the dew point temperature must take temperature measures. For bag-type dust collectors, the relationship between operating temperature and dust removal efficiency is not obvious. This is different from electrostatic dust removal. For electrostatic precipitator, temperature changes will affect the dust specific resistance and other impacts on dust removal efficiency.3Dust concentration at the entranceThat is, the inl
Recently, I took the time to read the objective-C and iOS development tutorials. The original intention is to be interested in these tutorials. This article is an example written by referring to the basic tutorial on iPhone development.
