I often felt that if a British Standard Finger could be packaged small enough and priced well that it would sell in vast quantities. Applying said BSF to various circuitry locations can make unintended oscillations stop, intended oscillations start, values drop into correct ranges, counters count, resetters reset, adders add and strong men tremble. A BSF is probably not up to performing the task of a mini-Helen.
