“The Most Beautiful Woman in the World”īy the time she was 23 in 1937, Hedwig Eva Maria Kiesler was a genuine film star in her native Austria. Starmade warhead movie#This is the story of Hedy Lamarr, movie star and inventor. Hollywood stars lined up to entertain troops and raise money for the war effort, and many joined up and fought too.īut one Hollywood star made an unconventional contribution to the war effort, and in the process proved that beauty and brains are not always mutually exclusive. Even Hollywood went to war, with its steady output of films that gave people a little glamour and provided an escape from the horror and loss of the war. Starmade warhead full#Young men and women enlisted and were shipped overseas, and those left behind kept the factories running full tilt. In America, it was a time when everyone wanted to pitch in. Video after the break.Ĭontinue reading “Even Joke Torpedoes Are Pretty Hard To Get Right” → Posted in 3d Printer hacks Tagged torpedoįor all the destruction and human misery unleashed during World War II, it was also a time of incredible creativity and ingenuity. We’ve seen others tackle similar builds before, too. We’d love to know how the Hackaday commentariat would go about solving these issues when undertaking their own build – let us know down below. On top of this, the matter of guidance is also an important one. There were issues with buoyancy, as well as providing the torpedo with enough power to move quickly in the water. The build, while undertaken for the sake of fun, does highlight some of the engineering challenges inherent in building a working torpedo. It also proved that the compressed air “warhead” could successfully discharge, albeit with less of a bang, more of a whimper. This allowed the torpedo to trawl, albeit slowly, through the water. Unfortunately, initial tests were underwhelming, with the rubber band mechanism failing to provide any real forward propulsion.Ī trip back to the drawing board was due, and the design was revived with a brushless motor powerplant instead. A soda bottle filled with compressed air is then used as a warhead, fitted with a contact fuse to release its charge on impact. The first revision consists of a 3D-printed hull, containing a rubber-band powered propeller. The build may have been done as a marketing exercise, but it raises some interesting questions about naval engineering. That said, it can be fun to experiment around, and does just that, attempting to launch a 3D-printed torpedo from a kayak. It’s dangerous, and usually frowned upon by local authorities. It’s rare that makers get involved in out-and-out munition production. Adjusted for inflation, that’s about $2.5 million.Ĭontinue reading “The Mark 14 Torpedo - When Just About Everything Goes Wrong, Even The Testing” → Posted in Hackaday Columns, History, Slider, Weapons Hacks Tagged engineering, mark 14, navy, torpedo, wwii Work started in 1931 with a $143,000 budget which may sound laughable today, but that was a lot of coin in the 1930s. Starmade warhead how to#The start of the story was the WWI-era Mark 10 torpedo which was fine for its day, but with faster destroyers and some additional data about how to best sink enemy ships it seemed necessary to build a new torpedo that would be faster, carry more explosive charge, and use a new method of detonation. The US Navy’s Mark 14 torpedo certainly has a lot to teach us. While you can learn a lot studying successes, sometimes - maybe even most of the time - we learn more from studying failure. After all, humans have been building things for a number of centuries and we should learn from the engineers of the past. I am a fan of the saying that those who don’t know history are doomed to repeat it.
