Over the last few videos I have highlighted helpful circuits. In this video, I highlight an active filter setup utilizing an operational amplifier. Filters are very helpful when working with analog signals. Often the range of frequencies needed are not across the entire band, therefore you need to filter out those that inhibit a clean […]

In today’s project on diyphysics.com, David Prutchi shows how to build a Cockcroft–Walton multiplier using a “ladder” of capacitors and diodes on perfboard, submerged in mineral oil, inside a sealed plastic container. The multiplier takes high voltage AC, e.g. from a TV flyback transformer, and both rectifies it to DC and steps it up considerably. […]
