If you don’t have a ready source of high voltage, here’s an easy way to build one from the aptly-named [HVZapp]. The parts list is pretty simple to acquire, except for the transformer. For that, [HVZapp] raided a broken arc lighter. It took us a minute to realize that the MOSFETs are in parallel. The hand-drawn…
It’s a great Christmas gift for those people who love electronics. In this project, I’m going to show you how to make this beautiful decoration with all the steps needed. The main components are NE555 and leds. These and others are THT components, that are easier to solder than SMD components. Also, there is no…
Breakout board based on the integrated 555 (SMD version), one of the integrated circuits that made the history of solid-state electronics. The 555 is a timer that can be configured in various ways incorporating a pair of comparators whose outputs are connected to the SET and RESET inputs of an RS flip-flop, so as to create…
