We present a power audio oscillator configuration which can be used directly on alarm, warning, other systems, driving a speaker. The simplicity of the circuit makes it ideal for low cost systems. The only active element in the circuit is an SCR (Silicon Controlled Rectifier).

We will talk about one of the most important components in all electronic assemblies: The capacitors. Many readers have huge doubts about the use of this component and especially about reading its values given the many existing codes. This article may clarify some of your doubts.
Why does light change its path as it passes from one medium to another? Why does a pencil placed in a glass of water look “broken?” This can all be explained by refraction. Do some simple but interesting experiments to understand what refraction is.
Have you set up a small transmitter and are not satisfied with its performance? See in this article what harmonics are and how they influence the performance of a transmitter and also how to use filters to have greater energy transfer to the antenna.
This amplifier uses an integrated circuit and is suitable as a booster for battery powered walkman, small stereo, record player and cassette player.
Texas Instruments has downloadable documentation on designing digital isolators. The Digital Isolator Design Guide which can be downloaded at: http://www.ti.com/lit/an/slla284a/slla284a.pdf is a 19-page document that will surely be of great use to anyone who needs basic information about insulators for galvanically isolated designs.
