A book for practical electronics

You have probably heard about this book. One of the best books I came across. The book name is

 ” Practical Electronics for Inventors”,written by Paul Scherz. This book follows practical approach towards electronics. While we have been following traditional methods to learn about electronics. You know our academic books contains full of formulas and equations. But this book doesn’t.
This book explains that what is what and how does it work. Let me give an example, If you have a transistor then it shows that how does it work and explains its applications with practical approach.As a said this book doesn’t have formulas means this book uses minimum formulas.If you read this you will really enjoy it.



This book is designed to help beginning inventors invent. It assumes a little or no prior knowledge of electronics. Therefore Students,educators,hobbyists will find this book is a good initial book. At the same time technicians and more advanced hobbyists may find this book helpful.

I believe that “Learning by Doing” method helps learners to learn easily and more efficiently. Because of that we don’t forget what we did.

What is a driver?

A driver is software it allows your computer to communicate with hardware or peripheral devices. Without drivers you cannot communicate with your computer properly. Sometimes it works but it does not work. A driver tells your computer to what it does. For example, Graphic card or Video card. It will not work properly without drivers.


Most probably drivers come with Operating System (OS), in windows you can find them by moving to windows update in control panel and checking for windows updates. If windows don’t have the drivers you need, it checks the drivers that came with your hardware. Otherwise you can find them on manufactures website.

Finally we understood that driver is important software. Our operating system contains some of the drivers integrated inside. While installing operating system it checks our hardware and it installs supported drivers.

The name itself(driver) suggests that it is a driver to drive it.

ఛార్మి హీరోయిన్ గా,సత్య అనే కొత్త కుర్రోడు హీరో గా తీసిన సినిమా “జ్యోతి లక్ష్మీ”. ఈ సినిమా తో ఛార్మి నిర్మాతగా మారారు. ఈ చిత్రంలో బ్రహ్మనందం తో పాటు తదితరులు నటించారు. ఫూరిజగన్నాత్ దర్శకత్వంలో ఈ సినిమా 12-6-2015 రోజున ప్రేక్షకుల ముందుకు వచ్చింది. ఇక కథ విషయానికి వస్తే ఛార్మి ఇందులో వేశ్యగా నటించారు. ఇందులో సత్య అనే కుర్రోడు సాఫ్ట్వేర్ ఇంజినీర్ గా పనిచేస్తూ ఉంటాడు. ఓకరొజు అనుకోకుండా జ్యొతిలక్ష్మి అనే అమ్మాయిని బస్టాప్ లో చూస్తాడు. ఆమె వేశ్య అని తెలిసి అన్ని వేశ్య ఇళ్ళళ్ళో వెతికి చివరకు జ్యోతిలక్ష్మి ని కలుస్తాడు. పెళ్ళి కూడా చేసుకుంటాడు. కాకపోతే అమ్మయిల్నీ కిడ్నాప్ చేసి వేశ్యలుగా మార్చే ముటాకి ఈ విషయం తెలిసి సత్యని  కొడతారు. జ్యొతిలక్ష్మి వాల్లని ఎలా ఎదుర్కుంది,ఆ ఉచ్చులో ఇరుకున్న అమ్మాయిలను ఎలా బయటికి రప్పిచ్చింది అనేది మిగతా కథ.

Wi-Fi can be used to charge your device

Ambient,Wireless charging as omnipresent as Wi-Fi? It is happening.

We use Wi-Fi to connect the internet. But recently the researchers has developed a Wi-Fi based technology to recharge your devices. We have seen wireless charging in many High end smart phones. But the technology is at implementing stage. This technology requires the device to be keep very near to the emitter ( One or Tow inches). Even it doesn’t have high enough to power anything indefinitely.

Our doesn’t have power to recharge itself. Battery is the greatest weakness to the mobile devices.
Battery technology hasn’t changed much in a last decade. Owing to this problem Google and other mobile manufacturing companies are investing huge money for figuring out how to make batteries last longer.

But what if you did not need a more powerful battery? And what if there were a way  to charge your mobile phone,no matter where you were,without having to plug it in? But we have Wi-Fi signals almost every where,Scientists asked themselves why didn’t we use these signals to charge a mobile device.
You can roam around your room holding your phone,and the wireless charging system supplies power to your device without noting you ever. This can be done with using ultrasound . A charging system that converts usable electricity into ultrasound waves. Which the system transmits through out the room or some area around it. In this process a small receiver is attached to the mobile phone’s case. This case catches ultrasound waves and converts them into battery power. No power cords and other hardware needed. Imagine the possibilities,college that charges your mobile phone and other gadgets.
