Electronic Projects

Each Graymark project comes complete with all electronic parts, cabinet, hardware, wire and solder necessary to build the finished product. Illustrated step-by-step assembly and experiment instructions are clearly presented in the academic level Instruction Manual included with each project.

EDUCATIONAL EXPERIENCES

A series of interesting, educational experiments during breadboarding or PC Board assembly assures high learning involvement. The HOW and WHY of each stage of electronic circuitry used is explained in detail, except Models 201 and 202.

MODELS WITH & WITHOUT BREADBOARDS

All breadboarding materials, including the Graymark-developed Breadboard and solder pins, are supplied with Models 216, 523 and 536. If price is important and you don't want to breadboard the project, select the NO BREADBOARD (NB) Model and save; the same parts and manual are supplied, but breadboard materials are not.
