Grandcentral open for Blogger users!!
Two days ago Grandcentral opened up its doors for Blogger users. All you need to do in order to get a Grandcentral account is to click on the Blogger invite link here and signup at Grandcentral. Please note that this offer is still available only to the US users, so, you know how to do ;) hint: proxy!! And you must also have a US based phone number to make use of the services. One trick is to have a free SIP forwarding number in USA if you are a VOIP user, or use a number like Skype-in, also there are many other providers in USA who provided free incoming numbers with their plan. With this method, you can make free calls within US and Canada too..Enjoy!!

Cheap ADSL Filter dissected.
There are many CHEAPASS ADSL filters available in most of the electronics shops in india. Costs around Rs. 40/- each. The function of this filter is, to make sure that the ADSL Signals don't interfere with the Voice signals and vice versa. Here is a circuit That shows a standard ADSL filter.
And the one Which I bought, Has just 2 inductor coils, value unknown, Wish i had an inductance meter.
Here is how it is wired internally.
Wall o--- IND COIL ---o Phone
Wall o--- IND COIL ---o Phone
There are no capacitors used in this circuit at all. And this method will not give an ideal low pass filter. L2 and L4 are needed since we're dealing with the 'Tip' and 'Ring' of a phone line. So, while it is cheap, be carefull when you buy these filters.
Will add actual photos here soon.
