Today's notebook market, are in the pursuit of ultra-thin, ultra-light, ultra-portable. Look at the hundreds of notebooks on the market, is not some feel that there is no characteristic? In fact, in the notebook field, there is a force that can not be ignored, it pursues performance, the pursuit of appearance, volume, weight is not in the slightest consideration, that is the Dell Alienware (alien) Series game Notebook, Tank products in the notebook se
Let's start by giving you a shot, which is one of the most expensive gaming desktops we've recently tested. For many users, a perfect PC host can be said to be the ultimate goal, it needs to be as small as possible, can be placed next to the TV and not seem out of place, but also have a strong performance, good upgradeable. The hard part is that the general power of a desktop PC is difficult to achieve in a compact fashion, but Dell's Alienware X51 di
Principle of stepper motor
According to common sense, the wiring of stepper motor depends on the color of the wire. However, the color of the stepping motor produced by different companies is different. Especially foreign stepper motors.
Then, the stepper motor wiring should be made with a multimeter.

If you're a traditional gamer who likes to use desktops to play games, then Alienware's 17-inch new Alienware 17 gaming notebook may be able to meet your requirements. The new Alienware 17 starts at $1499 (about RMB 9173) and is powered by Intel's fourth generation Haswell Core i7 processor.
In addition to custom-made, Alienware 17 also has a low, medium and h
Dell's new version of Alienware 13 is an example of what it claims to be the world's first 13-inch Vr-ready notebook.
The starting price for Alienware 13 is not high--at least for the brand--but 1200 dollars (about 8105 yuan). This cost allows you to get the Intel Core I5-6300HQ processor, NVIDIA GeForce GTX 1060 graphics, 8GB ddr4-2133 memory, 180GB m.2 SATA 6Gbps SSD, killer 802.11c Wi-Fi, Bluetooth 4.1
Alienware Aurora R5 Gaming desktop evaluation.
In fact, Alienware Aurora R5 is a product designed for VR devices, and we all know that VR-display devices such as Oclus rift often require a higher hardware configuration, so Aurora R5 is equipped with i7-6700k overclocking processors and dual GTX 1070 SLI's unique hardware mix is sufficient to meet the needs of VR devices and most games.

Basic Principle of stepper motor
1. stepper motor is an open-loop control component that converts an electrical pulse signal into an angle displacement or linear displacement. In the case of non-overload, the speed and stop position of the motor only depend on the frequency and number of pulses of the pu
From: http://www.eepw.com.cn/article/73889.htm
Stepper motor is an electromechanical component that converts an electrical pulse signal into an angle displacement or linear displacement. The input value of the stepper motor is a pulse sequence, and the output value is the corresponding incremental displacement or step motion. Under normal motion, it has a fixed number of steps each week. When performing Con
