Vacuum Tubes

On November 16, 1904 John Ambrose Fleming The Engineer responsible for the creation that would last until the beginning of the 20th century.

The First Transistor

On December 16, 1947 The first transistor was made of a plastic triangle placed above a germanium crystal, which was on top of a metal plate attached to a voltage source.

First Transistorized Car Radio

On April 28, 1955 Chrysler was the first company to create the first transistorized car radio. This car radio would be an option to add to your 1956 Chrysler or imperial car.

Pocket-size Calculator

On December 11, 1971 first single chip calculator is introduced. When a rubber button on a calculator is pressed the censor circuit underneath receives the signal and the keyboard circuit detects this.

DynaTAC 800x

On September 21, 1983 The first portable phone was created by Motorola. Motorola had previously created. So they needed to figure out how to minimize the amount of technology used to create a portable phone.

Pentium III

his was a microprocessor launched in early 1999. This microprocessor consisted of more that 7,500 individual transistors.
