Hacking Esquire's E-ink Cover
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."
I really need to stop mentally pronouncing it "E-squire".
who cares! until the magazine can read to me while I'm on the toilet, and answer my questions, or rebuttal my comments, I don't care how much technology goes into the cover.
Then again if Playboy gets a digital cover that talks dirty to me then I have the option of recanting my previous statement.
'mmmmmmmmm.... forbidden donut'
if someone went and re-flashed all the controllers in the Esquire mags to display porn (first thing that comes to mind is Goatse) instead of the original content?
Um, then it would display goatse.
Well, back to rejecting software patent applications.

Engineering is the art of compromise.
I don't get it. What do YOU think will happen?
All I can see is a company gets a black eye, blames the whole thing on 'those evil hackers', and sends a potentially cool technology away forever.
And if the first thing you think of when you think of porn is 'Goatse', man, I'm sorry.

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.
We need a new mod catagory for posts like the above: "blatantly obvious that they did not read the finagaling article".
It's impossible. These E-ink displays aren't pixel displays (which could show any image), they are segment based (like a cheap calculator, watch, or old LCD game). They can only display what they have been designed to show. Your only choices are for each segment to be dark or light.
Comment forecast: Bits of genius surrounded by a sea of mediocrity.
Not possible. While e-ink is sometimes used for general purpose displays (Amazon Kindle), for specialized applications its much cheaper if the e-ink can only represent compositions of static images in fixed positions, toggled on or off. Kind of like the difference between a modern LCD monitor and the LCD on a Nintendo Game & Watch-type game.

Great. The <blink> tag made it to real life!
Why?? Whyyyyyyyy........??? ;)
Any sufficiently advanced intelligence is indistinguishable from stupidity.

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...
Please help metamoderate.
I think -1 RTFA would suffice.

Success is not the result of spontaneous combustion, you must set yourself on fire.
For fuck's sake. Why not worry about all those greeting cards with sound chips in them, or all the alkaline batteries, or printer ink cartridges thrown away? Esquire doing a one-time limited run of these is nothing compared to all of the other sources of toxic landfill materials. Quit being a pessimistic asshole and pissing on the downsides of the current popular topic and worry about some real problems.

Then a bunch of artsy fashionistas would parade around saying that gaping anus is the new black.
Where does the school board find them and why do they keep sending them to ME?
Until they are programmable enough.
When I was in middle school, our typing teacher gave repetitive exercises like that, to do at home or in lab. I happened to have a daisy wheel printer at home for my TRS-80 (m4, 32k and 2 drives!), which was basically a - you guessed it! - typewriter.
A for-next loop and homework was done... even trimmed the edges so the perforation marks wouldn't be there to tip her off....
Don't blame me, I voted for Kodos
That's not an eye...
Yes this first feeble attempt is fairly lame, a few segments that will burn out in a couple of months and took a fair investment in hardware to pull off. But it won't end here.
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. On cereal boxes. Or having generic advertising, think shopping carts, seatbacks, etc updating their ad copy over slow radio links. And they already know how to make flat paper speakers so they damned things will be talking whenever somebody is in range.

I think you are misunderstanding the technology. Review: http://www.eink.com/technology/howitworks.html They are very much pixels, dots, or "e-ink microcapsules" which means you should be able to draw any image you want. In the howitworks they seem to have 3 shades: white, black, and grey. When you say you can only show what it was designed to that sounds like if it has an "1" you only get 2 bars like on a calculator. That is really misunderstanding what is actually going on here.
A pixel is just a very small, very square segment. I believe what the grandparent poster is trying to say is that this particular e-ink display is heavily segment based, and proposition supported by how it is being used in the cover and how cheap it is to make.
The cheap calculator displays are mostly LCD, which power both high end pixel-driven displays and the videogames that come free with your Happy Meal. This particular implementation of the technology appears to fall to the latter.
Hence, it would be nearly impossible to display anything other than what is currently on the cover without rebuilding the e-ink sheet. In this particular case, we're all winners.
The ______ Agenda
1995 called - they want their tag back.
> In the howitworks they seem to have 3 shades: white, black, and grey.
Unlike e-books, which apparently also have 3 shades: light grey, dark grey, and grey.
Which component in paticular do you think is toxic?
If the internet has done one thing for me, it has killed whatever curiosity I had to go look at new shock images.
I Am My Own Worst Enemy
Their website says they'd be interested to see what people do hacking it, and if you do something cool, please let them know. They say that it wasn't particularly designed to be easy to hack, and they don't know how, so you'll have to figure it out for yourself, but have fun.

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
