RFID Cookware

HaggiZ writes "Vitacraft are claiming to have what they call RFIQin Robotic Cookware (unfortunate name). It's basically pots and pans that you can place RFID cooking cards in the handle with. The communicate with the induction stove 16 times a second to adjust the cooking when required. Neat idea, although I'm not sure anything I cook needs to have it's temperature reviewed or adjusted every 0.06 of a second." For all the evil uses of RFID that have been floated over the years, it's nice to see that someone is going to finally make it so I stop burning my lunch.

For the millionth time, it's = contraction of 'it is'. its=posessive of it.

Re:Wrong target market.

Which leaves the only market being people with too much money, a love for new toys and no culinary skills. ...which explains why it's on /., I guess.

Here's what's really going on:

[Ancient_Hacker]

For those of you puzzled by this story, you should be, as it's basically bogus.

They're talking about inductive heating, which is a bit worrisome: It involves having a kilowatt or so of 13.56 MHz radio frequency energy beamin up at the cooking implement.

The pot can't be just any pot-- it has to hit a certain electromagnetic sweet spot, as to absorb the radio waves, and not reflect them all over the place.

this usually implies it has to be made of somewhat resistive and lossy material-- iron is a good choice.

Unfortunately materials that are resistive electrically are usually resistive, thermally too. So instead of getting a nice even heat, the pan is likely to have hot spots.

Ergo the pans really could use some sort of sensor to feed back to the stove some info about how the pan is heating. As to not have some cool spots while nearby the pan is melting through.

So this isnt so much a wonderful added feature, as a partial kludge to compensate for the basic foibles of the whole scheme.

Chocolate (and other candies)

[Anonymous Coward]

Chocolate, candies, and sauces come to mind. Especially chocolate.

Cocao butter in chocolate melts around 90F. Ideal melting temperature is between 40-45C (104-113F). Above that (45C, 115F), the chocolate scorches.

For tempering (the shiny coatings), you melt it at around 110F, cool it to 79-80F, and then warm it back to 90F. Automating it is very handy.

Candies (and related sauces) are very temperature sensitive. Sugar melts at 146C (367F). Just right and you get caramel. Just wrong and you get carbon.

Figure it out already

Hey HaggiZ, "RFIQ" != "RFID". Seriously, there are a lot of people out there calling anything small that passively or with minimal self-powering communicates via RF radiation (i.e. radio waves) "RFID". RFID is a specific thing. It's basically a small, cheap device that echoes back a unique ID number for tracking purposes. Calling this RFID is as fucking stupid as calling everything with 2 wheels and a motor a "scooter". Get a fucking clue, people.
