UP/DOWN FADING LED CIRCUITS

These two circuits make a LED fade on and off. The first circuit charges a 100u and the transistor amplifies the current entering the 100u and delivers 100 times this value to the LED via the collector-emitter pins. The circuit needs 9v for operation since pin 2 of the 555 detects 2/3Vcc before changing the state of the output so we only have a maximum of 5.5v via a 220R resistor to illuminate the LED. The second circuit requires a very high value electrolytic to produce the same effect.

LM3909 LED flasher

The LM3909 is an integrated circuit (IC) which will flash a light-emitting diode (LED). Using only two extra components and a battery, the circuit is cheap and has a very low current drain from a 1.5 V cell. The circuit can be used as a novelty flasher, an indicator for a dummy alarm bell box, or it could be attached to a torch so that it could be found easily in the dark!

USB POWER BOOSTER CIRCUITS

As we all know, USB port can deliver 500mA Approximately. but sometimes we might need more than 500 mA for our external devices. in this case we don't have any solution rather than by a USB hubs that have an external power supply. but in here i will give you good solution for our technical people. this simple idea can help you,

System Requirements for the SONY NSR

Network Surveillance Server

today im going to tell you about NSR.
NSR is the device from SONY which made for the CCTV IP solution.

Overview,

The NSR series is a hard disk recording server for network cameras. The NSR allows you to monitor and record network camera images (JPEG or MPEG-4). It also allows you to play back the recorded images and search through it, making the NSR a truly versatile monitoring system. 

230V vs LED's

there are many way's to lite up the led's from 230V

Attention. This circuit works with life threatening line voltage.

yo u can change the capacitor value 
for 10mA use 150nF, for 20mA use 300nF.

How to find and protect you'r product key

today i am here with another cool software. we all know if any crash with our PC's we have to format our PC.so in case if u format the computer then what happen to your software. (i am taking about original software its  not about pirate copy's). can you re install all. Ya you can but how you will register it still you have key for that all. i don't think so. here the best way to take your product keys. after you get the key you can protect them and re use.

Time to move to IP BUT....?

Ya its time to move, but we all know if we need to change our existing analog CCTV system to IP system we have to change the cameras, end devices and all cables also. but if we can use existing coaxial cabling system with the IP cameras it can save our money and time. for that SONY have solution, check this out.
