A worked Stepping Motor Example - Perhaps some of the most
commonly available stepping motors, for the experimenter, are the head
positioning motors from old diskette drives. These can be found at
electronics swap meets, in computer surplus outlets, and even in trash
dumpsters. In addition to a stepper, a typical full-height 5.25 inch disk
drive includes a 12 volt DC motor with tachometer....(Circuit design added

Accurately measure resistance with less than perfect components -
11-Nov-04 Issue of EDN For transducers, such as strain gauges or
thermistors, you must accurately and inexpensively measure resistance using
circuitry built with imperfect components and in which gain and offset
errors can significantly limit the accuracy of ohmic measurements. The right
circuit topology makes it possible to eliminate most error terms while
measuring ohms, leaving the accuracy to be determined by jus.... [Design
