ptorrone writes "I picked up the Esquire E-inked cover today and took a bunch of high res photos, for the makers out there. It has a programming header, 5-pin ISP, a Microchip PIC 12f629 which is flash programmable, 8 pin, 6 lithium coin cell CR2016s, 3 volts each. Two E-ink screens with flex connections — looks like it was made to be reprogrammed and different screens. The top screen has 11 segments, the bottom has 3. It was designed 2008-06-04. The PCB was made by Forewin, half thickness, 2 layer board (FR4). I think someone out there will likely reflash the PIC and make the segments go on / off at different times and perhaps put other displays on it, there's a little bit of hacking to be had but not that much really."

        Fascinating.

        All of it can be recycled through your local municipal waste program in the same manner as you dispose of household batteries.

        Last time I checked, household batteries go to the landfill. At least that's what happens where I live. GP has it right.

              No they don't have enforcement crews digging through your trash, but many business have drop boxes for their employees/customers, especially places like Best Buy. Retailers that sell rechargeable batteries are required to accept them for recycling. It's so easy to recycle them, and there are free programs [biggreenbox.com], so why not?

              A fear of getting caught isn't the reason people comply, it's to keep hazardous material out of the landfill. The same reason we recycle our electronics through free programs instead of burying them in the backyard (well technically the fee is paid at point-of-sale).

      My guess would be that this "screen" is not able to display arbitrary images, rather it can only display those images pre-burned onto the "e-ink". The PIC controller merely flips switches on and off at set time intervals or by button presses. Although interesting and indeed hackable, the hardware necessary to do this stuff is already quite cheap (something like $25 for a USB pickit 1 from Microchip.com).

        Right. The display is just like old Game & Watch games (or any other cheap LCD display). They have a bunch of segments (in this case mostly blocks of words) that can be turned on or off. I'd expect that just like LCDs the more segments you have the more expensive it is to manufacture the thing (not including the cost of controller).

        If you watch the little video that the Make blog post links to, you can see how limited it is.

        That said, it seems to refresh quite fast, which the e-books have problems with. I don't know if this is a consequence of the controller (I doubt it, Amazon/Sony would do better), the size of the pixels (smaller pixels switch slower for some reason, perhaps the small traces prevent higher current that can switch things faster), manufacturing (faster switching is too expensive to make an 800x600 screen), or just perception (since the elements are so large it's not noticeable like when you change small blocks of text).

          The problem with refreshing a pixel based e-ink display is that it has to be erased first (otherwise you get ghost images of the previous page). The erase setting has to be held long enough to achieve a stable and consistent state across the pixels. Some display modes of the ebook readers (eg, the mp3 player updating the play timer on the screen) don't do an erase first, and the update is quite fast (but you do get ghosting).

      Why are e-ink based e-books so expensive, while Esquire can afford to use it as a cover for their magazine? Something's missing here.

      11 very large segments versus 480,000 very small segments. PIC programed to go "turn on segment 1, then 2, then 3. Pause. Switch all them off. Repeat"...versus "fully fledged operating system and electronic document presentation system."

      Oh yes, and Equire printed roughly 233,300 of them (one in three of their circulation of 700,000) in one go. That's roughly equal to the 240,000 Kindle units Amazon has supposedly sold in about 10 months.

      Still, the biggie is the simplicity...

      • The hardware specs make a big difference, but the "fully fledged operating system and document presentation system" can be had for essentially nothing, if they pick open source solutions and tweak them a bit if necessary. That's what the Chinese [jinke.com.cn] are doing, for example.

    Soon they will put solar collectors on the things to keep it going indefinately, add more segments, etc. Hell, it won't be a generation before they are printing complex enough circuits on the damned things that they will be doing full motion video.

    When I first read the Engadget post about the magazine being available I knew I would be driving around all day to find a copy that I could hack. I finally got a few copies and ripped one to shreds as soon as I got home.

    Firstly, they did not use the active matrix version of the E-Ink display. It is a segmented version. This means that you can not make it do kindle like things. You must use the existing segments. The magazine contains two of these 2x5" displays. The cover display has 11 segments while the inside display has 3. They are both black and 'white' (aka grey) displays although several shades seem possible by varying the switch voltage timing. The color areas are created with a transparent overlay that, of course, is always present.

    (Note: These probably do not match the CN1 and CN2 pin outs)
    COVER DISPLAY SEGMENTS
    1. "THE 21ST CENTURY"
    2. "BEGINS"
    3. 1st box after "BEGINS"
    4. 2nd box after "BEGINS"
    5. 3rd box after "BEGINS"
    6. Both boxes (left and right) of "NOW"
    7. "NOW"
    8. The circle arrow
    9. Bottom box 1
    10. Bottom box 2
    12. Bottom box 3

    INNER DISPLAY SEGMENTS
    1. Left side + 2 of 6 'wheel' segments on both 'wheels'
    2. Middle + 2 of 6 'wheel' segments on both 'wheels'
    3. Right side + 2 of 6 'wheel' segments on both 'wheels'

    The cover display uses a 12 line ribbon connector while the inner display uses a 6 line ribbon with only 4 lines that are completed. One line on each display is a common connection while the others are simple on/off lines.

    THE ELECTRONICS
    The circuit board is very simple with only a few components. There are six CR2016 3V batteries, 2 connectors, 2 HEF4094BT 8 stage shift-and-store bus register chips, 1 12F629 Flash based 8bit CMOS microcontroller, 26 resistors, 2 capacitors and 3 transistors. The 12F629 controls 3 transistors that drive the STROBE, DATA and CLOCK pins, at 15v, of the HEF4094BTs. The HEF4094BTs are connected in a cascade fashion to provide 16 latching registers that directly drive the EInk displays.

    WHAT DOES IT ALL DO?
    The Batteries:
    5 of the 6 batteries (B1-B5) are connected in series to provide the 15v driver voltage that is used to change the segments from black to white and back. The other battery (B6) supplies the 3 volts needed to run the microcontroller. The B1-B5 series and B6 both share a common ground.

    The PIC
    U1 is the Microcontroller. This device controls the sequence of the changes.
    Pin 1 is Vdd (+3vdc).
    C1 is used as a noise filter for the power.
    Pin 2 is not used.
    Pin 3 is not used.
    Pin 4 is used for initial programming only.
    Pin 5 drives Q3 through R5.
    This drives the U3 and U3 STROBE (STR) lines causing the shift register data to be stored in the storage register.
    Pin 6 drives Q2 through R3.
    This drives the U2 and U3 CLOCK (CP) lines which allows serial programming of each register bit prior to storage.
    Pin 7 drives Q1 through R1.
    This drives the U2 DATA (S) line. U3 Data is connected to the O's (PIN 10) of U2 which is a serial output.
    pin 8 is Vss(GND).

    The Transistors
    Q1 drives the DATA (D) line of U2 and is driven by U1 Pin 7.
    Q2 drives the CLOCK (CP) lines of U2 and U3 and is driven by U1 Pin 6.
    Q3 drives the STROBE (STR) lines of U2 and U3 and is driven by U1 pin 5.
    Q1-Q3 base pins are connected to common ground.
    R1,3,5 are used for current limiting to protect U1 outputs.
    R2,4,6 are pull-up resistors for Q1-3 causing
    the output to be 15V when off and ground when on. C3 is a noise filter for the pull-up power rail.

    The Shift Registers
    U1 and U2 drive the displays. They are programmed by U1 via a serial bus. The parallel outputs we'll look at from the perspective of the CN1 and CN2 connectors. These work as a marching train of bits. When the clock goes HI all bits are shifted right and the first one is set the whatever DA
