First transistor

1947: John Bardeen and Walter Brattain, with support from colleague William Shockley, demonstrate the transistor at Bell Laboratories in Murray Hill, New Jersey.

The first transistor used two closely spaced gold contacts pressed onto the surface of a slab of high-purity germanium.

This is an Amplifier circuit diagram for 100 watts using 2sc5200 and 2sa1943 transistors. it's a mono board.

Different Types of Field Effect, Bipolar Junction, Depletion, Enhancement, Insulated Gate Bipolar and Special Transistors. Transistor means Transfer of Resistor. What is a Transistor? Classification of Transistors

In this post I have explained the making of simple delay timers using very ordinary components like transistors, capacitors and diodes. All these circuits will produce delay ON or delay

This is a transistor amplifier circuit diagram. this is a class AB amplifier. here used PNP and NPN Transistors.

This is an amplifier circuit diagram using 2sc5200 and 2sa1943 transistors. this is a 100 watts amplifier circuit diagram.

Digital technology wouldn't work without something missing at its heart. Richard Webb recounts the transistor's difficult birth

1966 One Transistor regenerative receiver.

Logic Gates With NPN Transistors: Hi guys, in this tutorial I will show you some NPN transistor based logic gates. What you need -A breadboard -A bunch of 5k and 10k resistors, and transistors -A LED You can use any NPN type transistor (for example 2N3904, BC547, BC548, BC549 etc.)…
