Have a Ratchet Screwdriver in Your Toolbox

Posted by chinatubularmotors on Monday, June 13, 2016, In : tool&equipment

Having a ratchet screwdriver in your toolbox becomes common used and easy in hand to operate. This hand tool can fix your screw effectively with cheap price and user-friendly. Hence, this type of screwdriver can work with easy steps.

First, choose the right bit to suit for your screwdriver. You should ensure that your tool will handle all types of screws. Next, insert your bits into the hole on the blade of the screwdriver tightly with your thumb and fingers.

When you start your screwing ...

Convenience of USB Flash Drives

Posted by chinatubularmotors on Friday, November 1, 2013, In : USB

USB flash drives use little power, have no fragile moving parts, and for most capacities are small and light. Data stored on flash drives is impervious to mechanical shock, magnetic fields, scratches and dust. These properties make them suitable for transporting data from place to place and keeping the data readily at hand.

Digital audio files can be transported from one computer to another like any other file, and played on a compatible media player (with caveats for DRM-locked files). In add...

Power LED Driver

Posted by chinatubularmotors on Thursday, October 31, 2013, In : LED

There are several common methods out there for powering LED's. Why all the fuss? It boils down to this:1) LED's are very sensitive to the voltage used to power them (ie, the current changes a lot with a small change in voltage)2) The required voltage changes a bit when the power LED driver is put in hot or cold air, and also depending on the color of the LED, and manufacturing details. So there's several common ways that LED's are usually powered, and i'll go over each one in the following st...

LED Voltage

Posted by chinatubularmotors on Wednesday, October 30, 2013, In : LED

The LED forward voltage drop will vary between manufacturing lots. Each time the LED manufacture produces an LED, the forward voltage drop can be slightly different from the last. Refer to the LED manufacture datasheets to determine the minimum and maximum possible forward voltage drops. Using these values along with your calculated resistor value, recalculate for circuit current draw. You may find that your current has drastically changed due to the voltage variation across the LED junction....

What is an OPC Server?

Posted by chinatubularmotors on Tuesday, October 15, 2013, In : Technology

OPC server provides a method for many different software packages (so long as it is an OPC Client) to access data from a process control device, such as a PLC or DCS. Traditionally, any time a package needed access to data from a device, a custom interface, or driver, had to be written. The purpose of OPC is to define a common interface that is written once and then reused by any business, or custom software packages.

All of the OPC Specifications are based on the OPC Client/Server model. Cl...

Introduction of the Audio Amplifier with Much More Powerful Amplifying Capability, the Audio Amplifier IC

Posted by chinatubularmotors on Friday, February 3, 2012, In : Electronic

Modest power audio amplifiers for driving small speakers or other light loads can be constructed in a number of ways. The first choice is usually an integrated circuit designed for the purpose, which is so-called audio amplifier IC. Discrete designs can also be built with readily available transistors or op-amps and many designs are featured in manufacturers' application notes. Older designs employed audio interstage and output transformers b...
