If you think yourself as a serious electronic researcher or hobbyists you would surely want to have the best of the test equipment on your workbench. The most important and perhaps the basic test instrument are the meters, which are so indispensable that electronic enthusiasts simply cannot think of working without these measuring devices. Here you will find homemade multi-meters in the analogue range using simple opamps, and also digital meters using discrete ICs, and if you are one of…

Before you can comprehend how a PCB transistor functions, you must first understand what a transistor is and what to check for when choosing one. Before you purchase a PCB transistor, you must learn how you should test one. What is a PCB Transistor? Transistors are electronic devices that regulate the flow of electrons and […]

First steps in radio, many often begin with independent fabrication of a transistor radio. Along the way, introduces the electronic components, acquired the skills in installation and work with measuring devices. And achieve rapid practical results is to the same positive stimulus for further study of fundamentals of electronics, gives confidence in their abilities and

7CW (MMBT2222A) NPN SMD Transistor. FEATURES: High current (max. 600 mA) Low voltage (max. 40 V) NPN switching transistor in The post 7CW SMD Transistor (MMBT2222A) Datasheet appeared first on Electrical Learner.

This radio was marketed under a number of brand names including Sharp, Continental (model TR-300) and Radionette (model 8R-48 or SR-48). Michael Jack has the Radionette version listed as model SR-48 on his Flickr post. A Faucher (Montreal) store newspaper ad lists it as model 8R-48.

The Transistor Turns 65 Years Old! It’s hard to imagine the change in our lives that has occurred in just the last 65 years since the first transistor was invented. This is an image of the fi…

How Electronic Switches Work for Noobs: Relays and Transistors: Hello, This Instructable is targeted at those just stepping into the world of electronics. In this guide I will explain how the two main types of electronic switches work, these being relays, and transistors. Firstly, what is an electronic switch?…

"The World's First Tubeless Radio" -- The Regency TR-1 transistor radio was first sold on October 18, 1954. The four transistor radio operated on a 22.5-volt battery that provided over twenty hours of life. It was priced at 49.95 USD.
