In October 2023, the author created a new PSU that worked well until it suddenly emitted a burning smell and failed. Upon inspection, a PCB track had burned out due to insufficient clearance. By fixing the track and replacing a transistor, the PSU was salvaged. To test it, the author built an electrolysis tank, recording voltage and current data. The results showed increasing conductivity with more baking soda. Despite design flaws, the PSU passed testing. The author acknowledges the need for proper insulation in future builds. The story ends with a humorous comment about the proximity of the PSU to a hydrogen-generating experiment.
