Recently I have visited a website which,  well you guessed it, is a site which reviews cloud-based storage providers. But what is a cloud-based storage anyway?

Here's my attempt at making a stereo LM3886T-based amplifier a couple of months ago, back in 2010. The gainclone gives a very good sound quality. It is like dead when the input signal is absent, no hum, hiss or any other noise. What you see below is the front view of my amplifier. You can see the am... Read More»

Another classic hello world post from me!! Well, there's not much to say except that this is my first blog post.
