Component Parts

  • Please see all component in figure 1 above.


Description

Circuit schematic like in figure 1 above is Circuit Schematic USB Rechargeable Power Bank using LM7805. The Power Bank circuit can be divided in to three segments for better understanding. First part of this circuit is AC to DC conversion circuit. Here a step down transformer and bridge rectifier is used to convert AC 230 volt to DC 12 volt. To filter the DC voltage a filter circuit has been used. Second part of this circuit is to stabilize the voltage and regulate to 9volt and then charge the battery. Here a diode has been used to block current flow in reverse direction. In the last segment another 5Volt regulator has been used so that it can charge your Smart phone.

ASUS A88X-GAMER, Special for Gamers and Overclockers - Motherboard Review

Robometricschool. - Riandanu Madi Utomo has wrote review about Motherboard from ASUS that called with motherboard is ASUS A88X-GAMER, Special for Gamers and Overclockers. This review has published in Metronewstv on June 14, 2015. In this moment we will show you about ASUS A88X-GAMER, Special for Gamers and Overclockers review like below.


ASUS does have various types of motherboards for the AMD platform, ranging from middle class to upper class. One is the upper class motherboards ASUS AMD A88X-GAMER.

Design "Red Kubu"


As the name implies, ASUS A88X-GAMER is AMD platform motherboards created specifically for gaming needs. This motherboard uses socket FM2 + which has been supporting the latest range of AMD processors, such as AMD Kaveri A10-7850K which we use to test it.

By design, this motherboard is suitable regarded as true AMD motherboards. He has a body with a combination of black-red color and very symbolizes AMD is often called the "red camp". Red color of the highlighted part of which surrounds the CPU heatsink and perched on top of the chipset.


To support the needs of gaming, ASUS pinned various efficient feature that allows gamers to maximize the use of its components, especially the graphics card. ASUS A88X-GAMER has been support for the use of dual graphics cards via the PCI Express 3.0 interface her. The use of up to two graphics cards allows game certainly be running more smoothly than using only one graphics card only (assuming the type and graphics card are the same).

Besides being able to sustain two graphics cards, this motherboard also has other excellent features, such as the use of dual channel RAM, use SupremeFX audio technology, to the overclocking features that are intended for those who are not satisfied with the performance of their PC.

Overclock Features Complete


Overclocking features are provided in this motherboard is quite complete. Not only for overcloker already highly skilled, they are still beginner can easily perform overclocking via AI Tweaker its features. Because the motherboard is also designed for the needs of overclocking, ASUS also pinned components with a high level of durability, such as the use of 10k black metallic capacitors, as well as embed various safety features such as DRAM overcurrent protection.

For performance, the ASUS A88X-GAMER considered to have a pretty good performance. He earned a score of 2481 on PC Mark test and capable of summarizing the data size of 1 GB into .rar format within 43 seconds.

Conclusion


ASUS A88X-GAMER is one of the best AMD motherboard from ASUS. For AMD motherboard category, the price is quite high, but at that price you will obtain a variety of special features that should be considered. In addition, the presence of a complete overclocking features on the ASUS A88X-GAMER also makes motherboard is suitable for overclocking enthusiasts.

EasyDriver Stepper Motor Driver

Robometricschool. - Do you need a good driver motor stepper with low price in this time? In here we will show you one of the driver motor stepper from SparkFun. This is EasyDriver Stepper Motor Driver from SparkFun like in figure 1 below.

EasyDriver Stepper Motor Driver
Figure 1. EasyDriver Stepper Motor Driver
Description

The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). EasyDriver requires a 7V to 30V supply to power the motor and can power any voltage of stepper motor. 


The EasyDriver has an on board voltage regulator for the digital interface that can be set to 5V or 3.3V. Connect a 4-wire stepper motor and a microcontroller and youâ€TMve got precision motor control! EasyDriver drives bi-polar motors, and motors wired as bi-polar. I.e. 4,6, or 8 wire stepper motors. On this version (v4.4) we fixed the silk error on the min/max adjustment.

This is the newest version of EasyDriver V4 co-designed withBrian Schmalz. It provides much more flexibility and control over your stepper motor, when compared to older versions. The microstep select (MS1 and MS2) pins of the A3967 are broken out allowing adjustments to the microstepping resolution. The sleep and enable pins are also broken out for further control.

Features:

  1. A3967 microstepping driver
  2. MS1 and MS2 pins broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth)
  3. Compatible with 4, 6, and 8 wire stepper motors of any voltage
  4. Adjustable current control from 150mA/phase to 750mA/phase
  5. Power supply range from 7V to 30V. The higher the voltage, the higher the torque at high speeds
