I'm cannibalising an iPhone 4S and making a new OS for it, just basic stuff like date and time, music, horizon indicator, temperature, then using a live feed from two cameras in stereo as the background. I'm using two of the 4S cameras, they have better picture quality than my lifecam and theyre smaller.
Lean manufacturing or lean production, often simply  lean , is a systematic method for the elimination of waste ( Muda ) within a manufacturing system.hile lean is seen by many as a generalization of the Toyota Production System into other industries and contexts there are some acknowledged differences that seem to have developed in implementation.
Quick Definition. Lean manufacturing is a comprehensive term referring to manufacturing methodologies based on maximizing value and minimizing waste in the manufacturing process. Lean manufacturing has evolved in North America from its beginnings in the Toyota Production System (TPS) in Japan.owever lean redefines waste. Traditionally waste has been viewed as an object. It is very easy to envision a barrel of scrap and identify it as waste. In lean manufacturing the term waste actually refers not to the physical material but rather the relationship of the resource to the end customer.
