This project contains the non-simulation schematic, BoM and PCB design for the EasyEDA Uberclamp Overvoltage Protection Circuit.
The attached photo shows the circuit clamping at the designed clamp voltage of 6V, a 3V/ms 5V to 9.5V transient. The trace starts on the left with both input (yellow) and output (magenta) traces at 5V. The input and output then ramp up together at about 3V/ms until t...
How to connect up two built and tested EasyEDA projects to build a complete replacement 5VDC and 9VAC power supply for the Commodore 64.
The design uses the EasyEDA Automotive 12V to USB 5V 2A output power adapter and Precision Commodore 64 Computer Saver PSU
overvoltage protection PCBs connected together with a 115V + 115V to 9V + 9V mains transformer, a pair of bridge
rectifiers, two 470...
This project contains several simulation schematics for the EasyEDA Uberclamp Overvoltage Protection Circuit.
It was originally conceived as a reverse input polarity protected, fast, self-resetting, current limited, overvoltage protector or Computer Saver for the Commodore C64 computer.
The original schematics were imported into EasyEDA from LTspice .asc files and have been edited to remov...
