Author Description

Berardi's Electronic Projects Quarterly 2016 FallThis issue is focused on building electronic projects for making a fairly sophisticated oscilloscope that is a standalone piece of test equipment. No PC computer or microprocessor is required. The OSCILLOSCOPE 5 project is complex by hobby standards and requires integrating three separate project boards to make a complete oscilloscope system.The first project board is the LED Graphics Display Board which has a 16 row by 32 column dot array. This board has a simple generic interface that allows being used for many applications.The second project board is the Data Acquisition Board which uses an Analog to Digital converter and the digital data is written into SRAM memory for storage. The digital data is displayed as a waveform using the previous project board. As in all of the projects, only through-hole technology is used allowing hobbyist to build this project.The third project board is the Interface 3 Board which provides the user interface for the controls, clocks and the control logic for controlling the signal capture and display process.The fourth project is the integration of the oscilloscope boards with a power supply into a cabinet making a complete oscilloscope project.All projects have documentation including schematics, parts list, wiring instructions, PCB artwork, test methods and color photographs.The author, a retired electronics engineer with over 24 years experience developing electronic products takes you along with his journey of building hobby projects. All of the projects are low cost and are a great learning tool.
