Ask Slashdot: Any Dishwasher Hackers Out There?
New submitter writes: I just replaced my dishwasher with a basic, inexpensive Sears model. It works fine, but only has 3 different wash cycles. I'm betting that the code to manage more cycles (as in more-expensive models) is already in the microcontroller and just needs inputs to select it. Is there any information available on this? Beyond dishwashers, have you done any useful hacks to household appliances more generally? I'd probably support a Kickstarter project that adds nice wireless notifications to my oven, clothes washer, and dishwasher.
Pretty much every single modern jet engine installed on current build airliners works this way. The hardware is the same, but the thrust limit is controlled by either the software version loaded in the EEC, or an "identification plug" which plugs into the EEC and acts as a switch to tell it which software limits to use. For example, the CFM56-7B which powers current production Boeing 737NGs is available in thrust ranging from 19,500 lbs to 27,300 lbs. The hardware is the same. The ID plug and the price is what makes them different. Pictures of the rating plug and how it works on a 737 here: http://nandang-smart.blogspot.... http://www.sjap.nl/cfm56-7-hyb...
