摘要

The Raspberry Pi was developed in 2011 as a low cost computer to teach youngsters to code. At $35US, this is a 'no-barebones-board', but a tiny, full blown computer with a 900 MHz quad-core ARM Cortex-Av7 CPU and 1GB ram on a 2.1"×3.3" board. The credit card size board is complete with a Micro-USB power connector, HDMI video/audio connection RCA video/audio connector, Ethernet connector, and 4 USB connectors. All the ports are ready to operate and can be easily software modified for additional capabilities. The power consumption is 700 ma at 5VDC. A standard tablet power adapter is adequate. The low power, small package, and inherent Ethernet capability make the system ideal for remote operation and control functions. The 'hard drive' for the system is a Micro-SD camera card. A minimum size of 4 GB is required. The native OS in the design is Raspian, a Linux derivative which can be downloaded at no cost. Microsoft saw the potential and has released a Windows 10 package as freeware for the Pi. In keeping with the Linux based philosophy, the entire system is open source allowing inexpensive access and unlimited modification potential. While working on projects, several family youngsters saw the 'cute, cool' little computer and wanted to play. The software comes with Scratch programming language, which was developed by MIT to teach youngsters to code. Scratch was used by one of the teenagers to activate robotic action. A tween girl 'played' Scratch, so she can draw very interesting characters. Two boys have used the Python language to program math problems. Obviously, the goal of a fun educational tool has been achieved. As a serious engineering tool, the machine is used for improvement of energy consumption. In the marginal well, oil production operation of Oklahoma, the wells do not pump continuously, but must be monitored and shutdown if out of fluid. We have designed a very sophisticated pump off controller using the Pi for a hardware cost of less than $100. The credit card computer is an educational tool, hobbyist dream, and economical engineering problem solver.
