This is a quick and simple project that is a bit old but still always a delight to see. Who doesn’t love staring at those high voltage sparks moving upwards again and again on the background of a mad scientist’s laboratory? Since we have a few high voltage transformers around here, I thought I could make a Jacob’s Ladder as a last minute project to add to the ones that would be presented on the Open Day.
Last Thursday, the University of the Algarve organized once more its annual open day, where it showcases their curricular offers to young students from all over the regional high schools. The Electrical Engineering Department asked us to be a part of the event and to prepare a small demonstration of our own projects to help motivate and inspire these young minds.
We recently got our hands on the Dangerous Prototypes Logic Pirate, which is an inexpensive open source logic analyzer. While it’s cool to see the PCB and the entire circuitry, this is the kind of thing that you’re gonna end up carrying it with you a lot, since it’s a useful tool, therefore our first thought was that it needed a proper enclosure to protect it from the rough environment that is the tool kit! And, since we have a LulzBot 3D printer, why not design a cool looking case that we can use.
