This article details the construction and use of the 555-timer checker. The 555-timer checker allows the user to dynamically check a 555-timer, an integrated circuit device. Of its many applications, it provides timing applications that unijunction transistors once performed. (Contains 4 figures and 3 photos.)

An electronic laboratory station was designed for student use in learning electronic instrumentation and measurement by means of the computer-guided experimentation (CGE) system. The station features rack-mounted electronic laboratory equipment on a laboratory table adjacent to a PLATO IV terminal. An integrated logic system behind the laboratory…

Twelve PLATO lessons are reproduced in this document to show the status of computer guided experimentation (CGE) instructional programs. The lesson topics include a description of the CGE-PLATO instructional laboratory, an introduction to CGE-PLATO tests and special software routines, router lesson for two electrical engineering courses, and an…
