Problem Statement

Develop power supply tester

Team Members

Summary

I got the project started. I began to assemble the circuit. I have researched how the project should be started. The board that will be used to mount the heat sinks and power resistors is set. I have also mounted everything on it. Circuit is startfed. Collected all nessary materials except for a 35 ohm potentiometer.

Story

Thered were many obstacles. In the beggining I had difficulty getting the wooden board attached to the metal casing. It took longer than it should have to get the power resistors on to the board. The heat sinks were not too difficult. I don't think that hot glue was the best choice to mount them with but future testing would probably be good to test it out. I also had some difficulty finding some parts required for the project. There is still the issue of the 35 ohm potentiometer. I still need to locate one. I spent a lot of time rearranging the circuit. The knobs don't seem to fit the potentiometers. I needed to lengthen the wires a bit to have the pots reach the sides of the metal casing. I did not get far enough to test the power resistor tester.
