Off Topic I brought up smell recording because I have always thought that it was the next step in recording. Three hundred years ago, nothing could be recorded. Then came photography and then phonography. Those to made an amazing progress in the meantime. While we have five senses, only these two can be recorded in different medium such as magnetic tape (analog or digital). Orfactory or tactile as well as gustasomething (taste) is beyond current technology's reach. Needless to say, tactile sensation recording device will be a billion dollar business finally enabling internet-interc.... hmm interaction between people. But what I wish to see is a technology that would record smell and reproduce it. Smell triggers so many memories. Of places I have been, I want to have the smell of it as well as its sights and sounds. It is comforting to know that SanDisk will be there (and the stock will go up) to record it when the technology finally arrives. James Choi

[Somewhat Off Topic?] >>Jim, I think they got equipment to detect explosives and toxic substances now, if I recall correctly (kind like your smoke detector in your home). After all, odor (or scent) is a gas that can cause some chemical reaction in the equipment. << Yes although the more common types of sensor used for analytical work do not react with an unknown chemical (solid, liquid or gas) but they probe it to determine the chemical composition using a spectroscopic technique. The spectrum of a chemical can be regarded as its finger print and then used to deduce what it is and thereby reproduce it (if this is the goal). The surprising problem is that the human nose although poor compared to most other animals is very good in comparsion to analytical techniques on a cost basis - this is why certain industries still employ people to taste and smell products - cheaper and faster than the analytical machines that would be required. The grocery line monitor is probably a freshness indicator that looks for fumes given off by microbes/algae on food that has started to decay (but not visibly so) - enables the supermarkets to narrow the margin of error in keeping produce on the shelves and thereby improve their bottom line. >>The flash will just store the formula for making it.<< The original post by Jim implied that the flashram would perform the processing and reconstitute the perfume - hence my ROFL: (incidently there is also ROFLPIMP - rolling on the floor p--ing in my pants). Although I am new to this thread (and SI) there does seem to be some confusion floating around as to what flashram actually does (stores information in a small, rugged, low power consumption, standardised format that is easily transportable from device to device) as opposed to what it can be used for (anything that needs to store information and has a premium on power, size, ruggedness and transportability) or am I misinterpreting some of the postings here?
