The world is always evolving fast and new technologies emerging, like metal 3D printing, but sometimes it just feels good to do things the “old” way. Don’t get me wrong, I love technology but still is great to learn old techniques specially when they tend to disappear when less and less people actually care to learn them and the craft becomes closer to extinction. Not that this is the case, although a few foundries have been closing over the last years. Be that an excuse or not, Gonçalo and me decided to build a simple DIY furnace, not only for the reasons above but we’re crazy about forging and metal working, and we would love to create some amazing metal pieces. Besides this is a dangerous project, what more do I need to say?!!
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.
