Current trends in Instrumentation of various types are towards using more and more electronic devices as part of their hardware. The use of microcontrollers with their associated software programmes are also increasing rapidly. This book is divided into four parts. The first two deal with experimental techniques in electronics plus components and special chemicals useful in instrumentation technology. The other two parts cover specific mini and major projects in a diverse areas of instrumentation. The Mini Projects include electronic test and measuring instruments, wind power, ballistics, and various sensor based devices. The Major projects cover data analysis, non-destructive testing, bio-technology and also a high voltage generator, originally developed for nuclear research. Some of the projects are very challenging. The book is aimed at stimulate the students' imaginations and bringing out their creative abilities.
