Experiments involving electrical phenomena in the biology lab are very interesting and even more interesting when we can use some electronic driving or monitoring resources. In this article, we describe a small experimental amplifier which can be used to track electrical phenomena in living things.
Here is a simple source, for the benchwork, which can be assembled even with scrap components and is ideal for the beginner maker. The transistor and the transformer are examples of components which can be used from disused devices.
High-frequency oscillators may be required in a variety of industrial and consumer applications, such as instrumentation, test bench, etc. Also important are oscillators of this type to repair AM or FM radio sets, receivers, tuners, intercoms, and others. A signal generator capable of producing high frequency signals with good intensity is indispensable. The apparatus described in this article produces a signal of good intensity over a wide range of frequencies and is modulated with an audio tone, which greatly facilitates its use requiring signals of this type.
This article is part of one of my books on Power Supplies where we cover everything electronics practitioners need to know about power supplies. It covers the operating principles of voltage regulators. At our section of books, the reader will have information to acquire the two complete volumes.
This assembly is the first stage in an even larger project for an electronic IoT scale. In this article, we will deal with a simple assembly where we analyze the analog part, which is simple, without going into the data processing part and sending the information to a central or another device. This assembly can be applied to learn how an electronic scale works and, from there, add improvements to the system until it becomes a scale for commercial or scientific use.
In an article in the components section (COM1066E) we announced the launch of Panasonic spherical lenses by Mouser, Many readers wrote to us asking if we are not saying spherical instead of spherical. The term really is aspheric and in this article, we explain what it is about with the applications you find in electronics.
