Inexpensive Cases for Student Electronic Instruments The function of component parts within the overall operation of instrument modules assembled for student use is best explained if the student can see into the interior of the unit. A convenient clear plastic cube of appropriate size is readily available in the form of a photocube sold to contain snapshots and available from photographic suppliers. The cubes are inexpensive, sturdy, easily drilled to accommodate various knobs and dials, and, generally, large enough for several integrated circuits and their associated miniature components. Small blocks attached to alternate sides serve for support of printed circuit and other mounting hoards. If each of several cubes contain individual functional modules, the cubes can he interconnected with banana plugs to assemble a variety of useful working instruments. Larger cubes, intended to contain a box of facial tissue, are also available from the cosmetic section of most large department stores. For boxes of other sizes, construction is possible using two wooden boards as one pair of sides and clear plastic sheets as the opposite sides, top and bottom. A saw mark on the inner face of each wwden board serves for support of printed circuit cards and the plastic ends, tap and hattom are fastened to the wooden sides with screws. This arrangement provides a quick, easily assembled and dismantled, sturdy box. Gordon A. P a r k e r University of Toledo Toledo. Ohio 43606
