Audio Intercom amplifier

Are you looking for a small audio amplifier circuit that’s not only cheap but also easy to assemble and can be done quickly? The idea presented here suits the need perfectly. It uses the IC LM386 which can be configured quickly by connecting just a couple of external components. The output power is not more than 1.25 watts which is reasonably powerful for low power applications as in door bells, FM radios, MP3 players, intercoms, etc. The amplifier is accompanied with some impressing…

Today I'm going to show you how to make your very own customized PCB (printed circuit board). All you need are some materials and tools like a: PCB board, A bottle of Ferric Chloride, A mini drill, A small container, A bottle of thinner and Some plastic tweezers. Making your own circuit board only takes a snap, what you need is 30-45 minutes of time. I thought of posting this Instructable since there are only few articles out here in the site about making a customized circuit board It is so…

Current, voltage and resistance are three important concepts in electronics. I didn’t have a clue about these things when I started out. But I could still build fun things, by following the circuit diagrams I found. I just didn’t know what was going on. When I started learning about basic electricity in school, many pieces …
