About this Episode
We welcome materials engineer Ian Doran as our first guest! Ian extolls the awesomeness of giant steam turbines and lost wax casting. He and Taylor share a few of their teenage adventures in idiocy and science. (Note: Don't put gasoline in a double boiler. Really... Don't do that.) Taylor explains knucklebones as an ancient method of random number generation and combines the old-school with the new-school. Ian brings the icosahedral heat! He tackled the bevel math that scared off Rob and cast some wicked spells on different salvaged materials. Rob thinks about rolling dice and... the dice roll. The Objet printer can give you a tattoo while doing a backflip. The Grr-ripper will help you keep your fingers on your hand. The step bit can make quite a hole. We have our first Patreon patron! Thank you Kelly! And we have our first listener feedback email! Thank you Rich!

- A Study on the Origin of Chinese Lost-wax Casting from the Perspectives of Art, Technology, and Social Agency. — ...early Chinese foundries could well have relied on using section molds even after they had already begun to use the lost-wax process with sophistication. This means that it is possible that Chinese casters had mastered lost-wax or similar processes considerably earlier. The question remains, was the lost-wax process independently developed in China, or was it introduced or perhaps its development stimulated from outside? When, where, why, and how was the art of lost-wax casting transmitted?
- The Long History of Lost Wax Casting — The discovery that metals could be melted and cast to shape in moulds was one of the major strides towards civilisation made by early man. Some time before 4 000 B.C., almost certainly independently in several different regions, and after long experiment with coloured minerals like malachite and azurite that had attracted his attention, man began the smelting of copper. There is no certainty about the dates of this first step in metallurgy nor about the exact locations, but in Anatolia, in the highlands of Iran, in Syria and Palestine, and even in Thailand, there is evidence of smelting around this time.
- Knucklebones (2016) - IMDb — A group of bored college students unleash a murderous demon while playing a dice game made from human knucklebones.
- Knucklebones - Wikipedia — Knucklebones, Tali, Fivestones, or Jacks, is a game of ancient origin, usually played with five small objects, or ten in the case of jacks. Originally the "knucklebones" (actually the astragalus, a bone in the ankle, or hock[1]) were those of a sheep, which were thrown up and caught in various manners.

- Introduction to Piezoelectric Pressure Sensors — Piezoelectric pressure sensors measure dynamic pressure. They are typically not suited for static pressure measurements. Dynamic pressure measurements including turbulence, blast, ballistics, and engine combustion require sensors with special capabilities. These capabilities include fast response, ruggedness, high stiffness, extended ranges, and the ability to measure quasi static pressures.

- Piezo Vibration Sensor Hookup Guide - learn.sparkfun.com — Piezo sensors are flexible devices that generate electric charge when they’re stressed. This characteristic makes piezos an ideal solution for low-power flex, touch, and vibration sensing. In more advanced applications, piezos can be the foundation for energy harvesting. Piezo’s are the perfect sensor for catching when your fridge is running or as the power source for energy harvesting shake-lights.
