Imagine you have a Hamshack Assistant named Alice that can keep your log, aim your antennas,remotely control and receive information from other computers, display satellite positions, teach Morse code, communicate in 16 digital modes, design antennas and manage the memory on your handhelds.
This assistant would actually be a $40 credit card sized micro-computer and micro-controller that can sense and control other devices. You can create Alice by reading and applying the book Hamshack Raspberry Pi which will teach you how to set up and configure the computer including adding a printer and WiFi. Then teach you to install Amateur Radio programs
Each installation section consists of an overview, any additional hardware required, instillation by two methods, configuration of the Desktop Entry file, program configuration and operation. Many screen shots are provided to illustrate the configurations.
In 1971 Intel produced the first general purpose programmable microprocessor chip, the 4004. It was one of four chips developed for a printing calculator. It delivered the processing power of the first computer built in 1946 which filled an entire room. This chip was followed by the 8008 and then the 8080. The latter was used in the Altair which became the first successfully marketed computer kit and set standards used for several years.
During the beginning of this personal computer 'revolution' the machines required more computer knowledge to operate than most people possessed. In the late 70s computer stores began to open but only customers with some computer background could successfully use them, as few well working programs were available. Just to put a program into the computer required using switches on the front panel is specific order. However these early computers attracted many young people who went on to college computer courses.
Over time the personal computer became an expensive household appliance. Parents were reluctant to allow their children to use the family computers because of the cost of the machines and the possibility of the children erasing the family data.
In 2006 Dr. Eben Upton and associates of the University of Cambridge Computer Laboratory noted the declining numbers and skills of students applying for computer science courses. It was decided to develop an affordable computer that young people could use to become familiar with computer concepts.
In 2011 the Raspberry Pi Model B was born and sold over two million units within two years. Since then there has been continuing improvements in various models of the Raspberry Pi. The machines are not only computers but they are also micro-controllers with pins that can externally sense and control devices.
Some of the uses, of these computers, are general purpose computing, learning to program, a project platform, prototyping products, creating a media center, control of robots, home automation and security systems.
The emphasis of this book is to provide guidance in setting up and operating a Raspberry Pi providing various amateur radio programs.
