#140 In this video I look at my old current probe in a bit more detail to see just why I wasn't getting the intended current to voltage ratio. As it turns out, the reason is not that simple - its a combination of measurement error and overlooking some of the parasitic aspects of how the transformer works...

#188 In this video I try something a bit more different than normal. Rather than talk about a specific technical subject, I want to take you trough my quest of building a power supply for home use. Its nothing particularly special, but it does not have to be, it just needs to work and be reliable.
