MEMS, or Micro ElectroMechanical Systems, are the enabling technology that brings us smartphones, quadcopters, tire pressure monitors, and a million other devices we take for granted today. At its most basic level, MEMS is simply machining away silicon wafers to make not electronic parts, but electromechanical parts. The microphone in your cell phone isn’t an electret mic you would find in an old brick phone from the 80s — it’s a carefully crafted bit of silicon, packed in epoxy, and hanging off a serial bus.
Despite the incredible success of MEMS technology, there is still …read more
We are fortunate to live in an age of commoditized high-power computer hardware and driver abstraction, in which most up-to-date computers have the ability to do more or less anything that requires keeping up with the attention of a human without breaking a sweat. Processors are very fast, memory is plentiful, and 3D graphics acceleration is both speedy and ubiquitous.
Thirty years ago it was a different matter on the desktop. Even the fastest processors of the day would struggle to perform on their own all the tasks demanded of them by a 1980s teenager who had gained a taste …read more
