Reverse Engineer Finds Kindle's Hidden Features

bensafrickingenius writes "CNET's Crave site has an interesting article on Amazon's Kindle eBook reader, and the extensive reverse-engineering that fans of the device have accomplished. The site specifically points out the work of Igor Skochinsky at the Reversing Everything website. His work on the Kindle's Root Shell has revealed some fascinating goodies: 'Among the ones uncovered and described on his blog are a basic photo viewer, a minesweeper game, and most interesting, location technology that uses the Kindle's CDMA networking to pinpoint its position. There also are some basic location-based services that call up a Google Maps view to show where you are and nearby gas stations and restaurants.'"

None of that fits well with a smart phone or computer (well, maybe for reading e-mail on the smart phone, but who wants to carry a smart phone which is already chunky enough in addition to an e-Ink panel). The reason eReaders are useful is because they're more portable (relative to data density) than a normal book, have search capability (or at least they should by now), and don't require any of the bulk or infrastructure more traditional devices require.

      Now, I'll agree a simple ePaper display would be cool, but ultimately it would only be useful after others built devices around it, which coincidentally happens to be exactly what's happening now. I mean, you can go and order eInk displays from OEMs if you know who to talk to, but they're really aren't particularly useful without some sort of data bus to back them. Know what happens when you make a bluetooth display without any other functionality? You end up with the palm folio. See what happened to that.

      A Bluetooth/USB ePaper display. Let a person's smart phone, computer render everything and tell the display what to do.

      A bluetooth monitor? Bluetooth can transmit at up to 2.1 Mbit/s. DVI can transmit 3.7 Gbit/s in single-link mode and 7.4 Gbit/s in dual-link mode. A 320x240 @ 24bpp would ideally take .9 seconds, but could easily take 5 seconds to fill the screen. And that is a tiny screen. 320x240 @ 8bpp would still ideally take .3 seconds. At a more standard resolution (1280x1024 @ 8bpp), a simple screen fill would ideally take 5 seconds and could easily stretch to 30. Granted, one could try to fix this problem by using a compression algorithm on the data, but PNG and JPEG aren't effective enough to fix the problem (especially in larger displays). USB would help, but it's still only 480 Mbit/s (I don't feel like doing the calculations again).

      Not to say the idea is entirely without merit. A worker in a server farm could load a problem ticket (@ 1 bpp?) onto his monitor and walk off with the ticket. There might be a few specialized applications for this, but everything involves writing some sort of specialized "painting" system, which goes against the basic idea of a monitor-only system.

      Current eInk displays have a resolution of about 1024x768 in 16 shades of grey and take around 0.9 seconds to update. 16 shades of grey requires 4 bits per pixel, giving a total of 3,145,728 bits per frame. At their maximum refresh rate the displays can handle, that means 3,495,253.33 bits per second. To squeeze that through a 2.1Mb/s bluetooth connection you'd need a 1.66:1 compression ratio which is pretty trivial with lossless compression for most images. More realistically, you'd want to run something like an X11 or display postscript server on it and just send vector commands.

      No.

      No external appliances to render the screen data.

      First, you need an expensive smart phone or even more expensive laptop to have it working.
      Second, battery life of the display would be moot, the laptop/phone would die hours earlier.
      Third, you'd waste lots of battery life of the device on transmission.

      I don't agree with any external device to render the contents. The reader, in 'reading mode' should be totally self-contained and portable. It can (and should) depend on a number of external devices for upload, conversion, purchase of books etc, but no external devices for actually -using- it please.

      The way I see it, the reader contains:
      * e-ink display
      * SD card reader
      * a microcontroller for display, keys etc,
      * a postscript rendering chip
      * standard batteries, preferably AAA.
      * rugged case with plain keys for interface.
      It would be neat if it opened like a book, providing two pages of display, protecting the screen from scratching and halving the size when not in use.

      The cost is low. SD cards currently provide the best price per gigabyte of flash storage, and you're not limited with internal storage - want to carry 200GB of books with you? Buy a handful of the cards, swap as needed. Plus being a standard, spare space can be used for whatever else you want, phonebook for your phone, camera, mp3 player. Just swap the card. And as removable media, it removes necessity for ANY other interfaces. No USB, no Bluetooth, no extra sockets, no drivers needed.

      Why Postscript? Because hardware to render it is 30 years old. It can be the same chip that is used in printers. Conversion to Postscript from mostly everything else is as easy as checking "print to file". It's feature-rich, mature, and has quite low requirements (6MB SIMM memory?)

      Standard batteries because you can buy a bunch of accumulators and keep them charged with external charger, never worry about expensive proprietary replacements, and as technology progresses, just buy ones of higher capacity.

      Keys, because they are cheap. touch-screen is fancy and cool but it costs a lot. And keys are just as good for the particular purpose. And a case that will withstand as much abuse as a hardcover book can.

      You've identified what you're troubled by - Kindle's like the old internet appliances and what's wrong with that - and what you'd like to see. I want to comment only on the first part.

      I disagree that ebook readers are bad because they cost only slightly less than computers but do so much less.

      The Kindle, like the 16GB iPod touch, both go for $399 - but so does one incarnation of the ASUS eee PC via quick search on Amazon. I'd have to believe that the eeePC does WAY more than either of the other two, but no one's going to give up their iPod touch for an eeePC because of form factor, ease of use and convenience for the specific use intended.

      I've been noticing what some users have posted about how much they love their Kindles, so by extension, I would no more imagine them giving up their Kindle than an iPod user would give up their favorite device.

      While there's some merit in what you say, remember that the internet appliance - by gaining market feedback (even if negative) - shaped other products and services and now it's easier than ever to get an all-in-one *something* that mom&pop can use to get a simple job done.

      The Kindle may very well have many flaws - vendor tie-in, software limitations, use limitations, strict targeting, high price - but those same factors haven't hindered the iPhone very much in the market (despite what many may dislike about the iPhone, its market acceptance and happy users are undeniable).

      I'm hoping that the Kindle excitement will help guide suppliers to innovate further in this field.

      Very old slashdotters will also recall this old ubiquitous joke - "In addition to our new software X doing A, B and C, naturally we were able to embed an ftp client in it as everybody needs one and you can't have too many ftp clients at your fingertips."

      2) Most laptops can run all day if the screen is shutoff, and minimal hard drive use. More to the point is, when using a laptop for work their is very little of the screen that I need active. IE I will have mostly static reference materials, and graphs of data. Then I will have a window that I compose my report/notes/program in.
      I can't fit this on a 2#, 9" Asus eee PC. so I lug around a 19" Laptop everywhere I go (that screen probably requires 4* the battery of a 9" also.) If properly supported By apps, and the OS, that external display would be perfect, probably more since it is tougher and lighter than current stand alone LCD, than the low power aspect.
