Gadget Freak Case #189: The Microcontroller-Operated, Pneumatically Actuated RLD
When Ed Nauman worked in his garage machine shop, the noise levels were often so loud he couldn’t hear the doorbell. He resolved the situation by creating a microcontroller-operated, pneumatically actuated doorbell... or a "Really Loud Doorbell."
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
