Power & Heat
Reducing power by design
Reducing the power in a circuit means reducing voltage or current. Hence the current move away from 5V devices to 3V3 or even 1V8 and lower. Modern micro controller systems often have a 3V3 interface
with a 1V2 core, requiring two supply voltages but dissipating less power.
That is... | {"url":"http://www.thebox.myzen.co.uk/Tutorial/Power.html","timestamp":"2014-04-21T12:09:43Z","content_type":null,"content_length":"19691","record_id":"<urn:uuid:a27bc20d-156f-4789-b79f-37f7b1d5af47>","cc-path":"CC-MAIN-2014-15/segments/1397609539776.45/warc/CC-MAIN-20140416005219-00267-ip-10-147-4-33.ec2.internal.warc... |

Conservation Laws
What Pete and Ich were describing can be summed up in the conservation of the
