Today There is Typhoon In Our Country

We are experiencing now a typhoon in our country in Philippines. Here in cavite, my place, we have a signal 1 and we have a medium rain falls and a little heavy gustiness of wind. But in northern part of our country where is the center of the typhoon experiencing heavy rains and heavy gustiness of winds which is signal number 3.

Have you ever had an LED or other diode placed backwards? By us? By someone else? By yourself? We don't like it when that happens and we're sure you don't either. Screaming Circuits strives to place every component, from the largest, highest pin-count logic chip down to the smallest passive components, correctly every single time. A key element of that accuracy is our understanding of your board and the component markings. If you use surface mount diodes or LEDs, you probably understand the challenges involved in correctly and consistently indicating diode polarity. LEDs are usually cathode negative, while zeners and uni-directional TVS diodes can be cathode positive. Barrier diodes can be either orientation. It all depends on whether the diode is a rectifier, an LED, a uni-directional TVS, part of a daisy-chain and a host of other considerations. When you start looking at the CAD libraries, you not only have all the differences from that manufacturer, you may also have different markation schemes from each CAD package developer and from each library builder. Guidelines for diode polarity mark silk-screening – “A” for Anode or “C” for Cathode.

Manila International Bookfair

This coming September 14 to 18 there is an international book fair. I hope i can go there to look for some helpful books. Like in electronics subject. If in your country there is an event like these try to visit to expand your knowledge.

Here are the top 10 energy that consume the most energy.

Here are a few strategies:
Use a switchable power strip to pull the plug on clusters of computer or video products.
Buy low standby products if you can find them. Don't ask a salesperson though because they probably won't know. Better to look for ENERGY STAR products, which are tested for profligate reliance on standby power.
Buy a low-cost watt-meter, measure the devices in your home and take targeted action.
If all else fails, pull the plug, but be careful not to get electrocuted in the process.
Here are the top 10 energy that consume the most energy.

A generic DMM test and calibration strategy

The Digital Multimeter or DMM is one of the most widely used electrical measurement
instruments and provides electrical traceability to many industrial users. However, it is
the nature of measurement products that they require regular checks to ensure that
they operate not only in a functional sense, but also within their specifications. Such
regular checks are known as calibrations and require a certain amount of knowledge
of DMM technology in order to calibrate them effectively. This application note seeks
to identify the important functional and calibration parameters and to offer a generic
guidance strategy for their routine verification. Click here for the link:http://cancomdigital.com/resourcecenter/assetsrc/Fluke_GenericDMMTest.pdf
