World’s largest e-paper sign

Some of you may remember I have been asking the question, why is there no large eink/epaper displays/screens? Then I came up with a solution which could scale (maybe) by creating a kindle array.

Well someone nicely pointed me in the direction of this article which claims to have the world biggest epaper sign. As you can see its really an array but its still pretty impressive.

Its also interesting to see where else epaper is being used.

Large eink displays?

Maarten Pieter emailed me after reading my blog post asking why there were no large eink displays and then my solution building a Kindle array.

Dear Ian,

I came across your blog on large e-inks displays and the kindle array idea. Have been looking into this myself for some time now but not found a good solution yet. There is another initiative out there from a Japanese company called soken to create a Eink wall.This would be what I wanted but by now I settle for the NEC a3 screen 😉 (which btw is supposed to have only a 1 mm border so could make tiles as well). I was wondering if you made any progress with your project or inquiries. I did not contact NEC yet did you give it a try?

I have some ideas on the software but the hardware is staying elusive and indeed it is not clear why these devices are not on the market. I am now considering contact some local people connected to Philips here in the Netherlands and see if they can explain why these large screen are not here. Some years ago I worked for a newspaper company and during my research in that period I know there was a test production line producing epaper. I think it will be hard to make the kindles fit well together but otherwise it is a good idea. Another lead would be http://www.epapercentral.com/ but the blog died some time ago though gives a good insight in what is happening.

kind regards,

Maarten Pieter, Netherlands

I did contact quite a few eink vendors but never got a reply… I did float the idea at work and it went down well. However I later found a photo of a large eink display prototype somewhere and I’ve become maybe too busy to experiment in the area myself right now… The A3 sized eink displays sound great and a 1mm border means its almost perfect for setting up an array!

Thanks to Maarten for emailing me and hopefully someone will email me and say, hey its been done or I’ve started work on the eink display array (good old lazy web style)…

Eink demos

Sriram Peruvemba, vice president of marketing at Eink, gives us the latest news from Eink, they announced that they will ship between 25 million and 30 million Eink screens this year, just for the Eink e-readers like the Kindle 4 and Nook Touch. Yup you read right, 30 million of those devices to be sold this year.

Is it only me but does the device he’s playing with look exactly the same as the new touch screen Amazon Kindle? Can’t believe I didn’t spot it before really. Anyway its a interesting little interview, but still odd there not going for the bigger display areas?

 

Kindle Array the answer to the large scale e-ink display?

First Rasterbation

I have been asking the question over and over in different circles, is there such a thing as a large scale eink display?

It seems the answer is no but I’m more interested why not?

Then yesterday while at lunch with a couple of colleagues in BBC R&D, Robert was asking me questions about my Kindle because he was considering buying one for his girlfriend and I was running through the advantages and disadvantages. Somewhere in the conversation, Andy mentioned my question about a large scale eink display (the advantage of being public again). I explained why I think it would be good and somewhere along the conversation one of us 3 suggested (think it was Andy) taking a Kindle apart and stitching them together.

I had quick thought, you could make an array of kindles and then control them to display what you want. My next thought was if you could tile post to the Kindles/eink display.

And that was it! An array of eink displays fed the right part of the whole document.

The advantage of a Amazon Kindle over a standard eink display is the wifi radio and email address, which means you can send each one a document remotely via something like rasterbator and if you can control them, you can remotely make them display a document as a screensaver. Later in the lab while eating cake (we seem to eat cake quite a bit on Fridays) I thought maybe this could be done via Arduino using the USB shield. Practically you would only need to root each Kindle using this method. Then by uploading a slightly different image to each one, you could create a tiled display or as I’m calling it a digital array.

Ultimately you want some software running on a Kindle which you upload the document/image to, it interrogatives its neighbours to work out how big the array its in is and only displays the part which makes sense. Because the Kindle is running gnu/linux, it would be possible but to be fair I’m not even going there, but if someone else wants to be my guest.

I’ll be hacking around with this concept in the near future, and welcome any thoughts or ideas on this idea.

Currently I’m just double checking if there is a large format eink display and trying to work out what is the best eink display to start with? The Wifi Kindle makes sense because its cheap enough, software hackable and easily hardware hackable. Although the Kindle DX does also look pretty good. I’m hoping for the Kindle Fire sale to start pretty soon, maybe.

My manager Adrian at work set me the challenge of putting our whereabouts system on the array or even the MCUK status updates. Right now, I’m going to just get two going then build on that… Hopefully there will be more details as and when it happens…

An update…

Of course I’ve been doing my research and it seems NEC created a A3 size eink display a while ago, it also seems I wasn’t the only one thing about turning them into tiles.

Additionally, e-paper modules can be used to form large screen displays by combining up to eight modules, which incorporate the company’s original multi-tiling controller. The A3 e-paper module is composed of especially narrow frames, with two sides measuring just 1mm, which enables the creation of large screens that feature effective multi-tiling

Also I noticed on the eink site… This recent picture…

2.4 meters certainly counts as a large eink display… So the question is how do we get our hands one and how much do they cost?

Well I’m looking at NEC, Neolux and  Motion Display if there listening…

Hacking together my digital artifacts with a wifi picture frame

My Wifi UPnP digital picture frame

For a long time now

I’ve been thinking about the problem of digital artifacts in a physical world. I remember clearly, a fantastic conversation I had with the amazing Jas Dhaliwal about this exact subject when he was up in Manchester recently.

He was looking through my book collection and DVD collection and we got talking about how most of the books on my shelf I’ve never actual read through. Not because I don’t read but because of my dyslexia and I far prefer to read digital books. Which begs the question, what am I doing with a ton of interesting books? Why don’t I just get rid of them and buy the digital equivalents?

Well two reasons…

  1. Physical artefacts are much easier to lend to people and much more likely to be taken seriously by friends currently.
  2. Physical artefacts are easier, cheaper and better suited for display.  And I want to display who I am through my choices of the media I buy (rightly or wrongly*)
* Now you could have a massive debate about should you be defined by the things you own or what but… frankly this isn’t the time do that.
As Jas said in the latest techgrumps, its all about the digital artefacts representing you… And with that all in mind, I bought a wifi enabled picture frame for a very good price at my local Currys outlet store.
I bought one before but it was crap because it couldn’t connect to anything on my local network, just remote services. However this one does have the advantage of Universal Plug n Play, which raises it above most of the wifi enabled picture frames.
I complained on the same techgrumps podcast that I couldn’t get anything to talk to it but I finally used Ushare and bingo everything started working. So right now, I got the plan to either,
  1. Install Ushare on my xbmc box so I can share movie fan art and titles from XBMC
  2. Setup a rsync between my xbmc box and my server (already running uShare)
  3. Move the xbmc database to my server which has the benefit of a shared library system.
  4. Investigate the built in xbmc UPnP server
Either way, it looks like I’ll be keeping the photo frame strictly for the purpose of replacing my digital film collection with something an analogue artefact. This is also where a large scale eink display would be ideal.
I’ll post something along these lines on the XBMC forums to see what people think. Maybe they might even be able to help, the recent fan art stuff certainly will help too

Why is there no large scale eink displays?

Data visualization in bbc Manchester

I took a picture of a paper display in the BBC Manchester office the other day

It seems like every week they may replace the old informational display with a new one. But it got me wondering… its quite a simple visualisation and yes you could project the same thing or even put it on a large lcd screen but why not a massive eink screen instead?

Then I did some digging around… Where’s all the large scale eink screens?

From wikipedia

Other proposed applications include digital photo frames and information boards

But where are the information boards? Sure they will be expensive but over a course of years they can’t be that bad compared to a projector or a large LCD display

My only thoughts are…

  • A large eink display won’t be as cheap as paper, so no ones really attempted it
  • eink is difficult to scale in some way?
  • eink power consumption ramps up the larger you go?

So odd because I can certainly find reasons to use a eink display, even a A3 and A2 sized display. Imagine photo frames which you can change every once in a while but very flat and light. Perfect for hanging on the wall…

The ebook dilemma

My sister and I spoke on Skype the other day and I said to her I finally got around to reading What the Dog saw by Malcolm Gladwell which she bought for me about 2 years ago at Christmas. Yes about 2 years to read a book (of course it didn’t take that long in reality) but it did take a while in between all the other stuff I was doing. I guess I should have read it while I was in hospital last year.

She said she had watched a programme on BBC Three called Kara Tointon: Don’t Call Me Stupid. It was all about Dyslexia. And she had kind of got it. I had watched the same programme a while ago on demand and to be fair I did think it was going to be crap but actually it was pretty good, even though I had never ever heard of Kara Tointon, and to be slight blunt don’t really care.

I’m a hard person to buy presents for and of course I want to make it as easy as possible for loved ones to buy stuff for me if they would like to. Books are a regular choice but they usually end up on my book shelf and read by myself sometimes up to a year or so later. In actual fact I have a fantastic book which Si Lumb lent me a while ago around late Summer. called Last night a Dj saved my life. Its right by my bedside but I’ve never read more that 5 pages of it so far.

We talked about the possibility of ordering a ebook and sending it to me via Amazon’s Wispernet but it worries me. So far I’ve never bought a kindle book, just uploaded ebooks from elsewhere. My problem with ebooks is simply the DRM. Yes I have a kindle right now and there’s readers on most devices and platforms (no linux client by the way, but there is a web client now) but what happens when I don’t? What happens when Sony bring out a decent ebook reader which is colour and half the weight of the kindle (aka the weight of a feather) or maybe someone develops a foldable eink display… How am I going to move my books from the Kindle to what ever? On top of that, don’t even get me started on the sharing aspect….

So in light of this, I suggested to my sister that she should in future just get me Amazon gift tokens and I can use them for books or ebooks. Its not as personal/nice as buying a book but it also works and theres much more chance of me actually reading it.

Instapaper’s wireless delivery

I didn’t notice Instapaper now supports wireless delivery of epub’s.

Reading on the Kindle’s non-reflective, e-ink screen is easy on the eyes and great for longer content.

Instapaper provides Kindle-compatible files, easily transferred at no charge via USB, containing the Text versions of your saved pages in any folder.

Additionally, you can set up wireless delivery to automatically send your most recent Instapaper stories every day or week. Note: Amazon assesses a surcharge for each wireless delivery, and wireless delivery is not available in all countries.

Instapaper also provides ePub files for other electronic reading devices that support ePub, including most Sony Readers and the Barnes & Noble Nook.

Ok besides the Amazon surcharge (which doesn’t seem to apply if you have a wifi only kindle it seems), this is fantastic. I use to use Instapaper but switched over to using Readitlater. I might have to switch back? At least till readitlater enables the same feature (i and others have already suggested it)

My Kindle is here, and I love it!

I got a delivery notification in my letter box today saying I missed a deliver and the caretaker took it in. Wondering what it could it be, I looked in my inbox and found…

Yeah!!!! I got my Kindle3, so expect tomorrow a unboxing using my new camera. Its been ages since I ordered the Kindle and I’m so glad its came.

So now’s a really good time to sell my Sony e-ink PRS600 reader, although its got a slight scratch which means CEX won’t buy it off me. Its well used and served me very well in its short time.

I got the device in my hands now and yes there is a nice series of unboxing photos on flickr.com if your interested.

What really got me was the amazing difference between my old Sony PRS600 and the Amazon Kindle 3. I know the Sony PRS505 vs Sony PRS600 was always a challenge because the PRS600 had the touch screen over the top of it. But boy oh boy, the PRS600 vs the Kindle3 is shocking… I can’t believe how clear and crisp the screen is. Then there’s the weight of the device! Its almost too light, I feel like I’m lifting a paperback book! Just like the Sony, when you plug it into a computer (yes even Linux) it comes up as a mass storage device, allowing you to just shift stuff back an forth easily. Of course Calibre allows you to easily convert between ebook formats and sync with the kindle directly.

My own complaint so far is the wifi won’t connect to my wireless network, but actually I think what’s going on is my local network isn’t actually connected to the internet yet and its failing to touch the internet and giving up. But over all this device is amazing! They have done so much, even down to the screen saver (as such, because of course with a eink screen you don’t need one) which is displayed when your charging the device. I can’t wait to get the experimental browser working (actually going to the northern quarter later to try it out) and try out some of the kindle apps. I’ve not looked into the Kindle hacking yet but this is certainly one of the massive advantages over the Sony.

This has to be the first break through e-reader… Just over 100 quid for a amazing device! Can’t wait to sit out in the shared garden reading on this device.

The Kindle3 has everything I asked for…

Sony PRS600 vs Amazon Kindle 3

I’m going to sell my old Sony PRS-600 Ebook Reader for the Amazon Kindle 3. But why?

Well it kind of centres on a blog post I wrote a while ago when the iPad was unveiled to the world. In the blog post I touch on points which would make my perfect ereader. 2 of the main points are,

  • Add Bluetooth for file transfer, dialup, networking, etc.
  • Run an open operating system like a cleverly crafted Andriod on it
  • Add accelerometers, proximity sensors and some haptic feedback
  • Wireless 802.11b/g

Well although not all my requirements are met, the Kindle3 does have wireless and a operating system to support (as such) 3rd party apps.

Android would be great to have on there with a open marketplace so people can really develop for it. I don’t know if Android would work on a e-ink screen but you could imagine it wouldn’t take much to build a custom build just for E-ink screens. Bluetooth, Wifi and Accelerometers would open up a whole bunch of applications which the ipad has demonstrated. But the smaller screen would be much more mobile and friendly.

I assumed slightly wrongly that you would need android to have the ability to add apps, but actually Amazon have decided to go with there own OS and App platform. This might be a good idea because you don’t want apps made for a Lcd mixed up with the eink ones. Its also a good idea if developers are thinking about eink instead of building for Lcd and just converting down to eink. Battery life under ink is amazing, but I’d hate to see that going because some app took liberties with the eink technology. Kindle apps are certainly a new area with a fruitful future. I can think of some clever apps you could build with the eink screen.

I thought good and hard about swapping to the Kindle, specially with the 1984 uproar. But to be frank, I’ve never bought a ebook and won’t really be affected by this thing. I would have also perfected a open market place like Android but its the start, so who knows what may happen…

I also downloaded the kindle app on my android phone in preparation for my new Kindle (which has been ordered but I’m still waiting for stock). In the meantime I’m selling my lovely Sony PRS-600, so if anyone is interested drop me a message.

Playing with the ipad my thoughts

Ipad

So while in Ireland for Media 2020, I got to play with a couple of people’s iPads. Now you all know I’m not a fan but these are my honest thoughts while playing with it.

Its bloody heavy, I expected it to be much lighter. When you use two hands its ok but I can see why people end up resting it against something for a while. The screen is vivid but you can see the pixels easily and even worst with apps which are blownup using x2 option. Reading an actually ebook was disappointing and felt like readiing from my on laptop. Adjusting the backlight down helped but no where near the ease of eink.

Why is it curve on the back? It seems to make even hard to hold and its not helped by the shiny back. I really would not want to carry this in a crowd in fear of it slipping out of your hand due nudges and the usual human traffic or if someone really wanting to nick it off you. Talking of which, what on earth kind of glass screen tech are they using? It picks up greasy finger prints in seconds. Not good.

Finally I thought it was meant to be slightly bigger that my Sony Ebook reader, no actually its exactly the size of two of my sony ereaders side by side. Which says to me its far too big. One of the people who had bought one had a special rubber case which i guess helps it stay clean but geez its ugly. Obviously not designed by Jon Ive.

There is something about E-ink which is changing the way I read

Ereading from the beach

I no longer like to read on my LCD screen. Its just not the same.

Eink is lovely to read on and for me changing the widths of text is still a dream come true. Its really changing the way I read and I can’t help but pull it out when I got a spare moment or two. What I’ve also got setup is the regular morning syncing. Every morning when I wake up there is a selection of news from places like ars techinca, the guardian, etc on the device ready to be consumed. I then also have it setup so that if that book goes out of date by 7 days, it will be removed from the device automatically. Its all down to a great piece of software called Calibre.

I do kind of wish the Sony Ereader did have wifi or at least bluetooth so it could remotely do what Calibre does but to be fair its not a big deal leaving the ereader synced over night, just a bit pointless because the battery life is weeks at a time.

I’ve got Google Reader working with Calibre but the documents it creates are so big, navigating them on the Sony Ereader is painful. I either need to modify the script so it creates smaller chunks of my whole Google reader account or sort out the massive amount of stuff I don’t read on the account. Maybe a bit of both sounds right. Another reason for the wireless would be to tell Google that I’ve just read a article so I don’t have to read it again on my laptop, but with no actual API for that on Google Reader and no wireless on the Ereader, I guess I’m double out of luck.

Lastly a bit of colour and speed would be great. I’m not suggest the same as LCD or even OLED, in actual fact eink is great but I like the idea of colour eink even better.

The Apple iPad: Underwelming but not a bad price

Apple Ipad

Apple release the islate, itablet as the ipad today. I’m sure many people will write about the device and how they really want one but even with my mac bashing hat on the table its not enough.

If you’ve not seen it, think of a ipod touch and grow it quite a bit and you got yourself a ipad.

The first thing which puts me off is the size, its too big to slot into my life. I want something which I can discreetly hold on the bus without people going hey whats that he’s got there? Something you don’t need another case or bag for. Something I can just carry with me just incase I got 30mins to do something. Some of you will argue that the smartphone is that device but I’m not so convinced. Its also quite weighty, which don’t get me wrong – is good for a large LCD but I want something really light. The real deal breaker and to be fair this was always the case even before it had come out. The Apple App store and Apple Ecosystem.

I can’t express how sick to death of the Apple Ecosystem I am. Everytime I even consider the ipad, I think about my experience with the ipod touch I bought last year. I couldn’t even turn on and use the device without the device talking to iTunes, which meant installing itunes on a work machine to just use the damm thing. Then there was the problem with storage. If I wanted to transfer something over to the device, it had to be via iTunes again. Not even Bluetooth push/ftp/send would work.

Compared that experience to my Sony Ebook reader. First day, I plug it into my Ubuntu machine and it pops up as a storage device with simply named folders for ebooks, pictures and audio. This also means later I can do automated file transfers from any media player I’m using at the moment (I tend to bounce between Rhythmbox and Banshee). Yes the Sony is a less complex device but they got the basics right. In actual fact the Sony ebook reader is the model of what I’m looking for. When I first bought it, I never knew I wanted something like it for size and use outside of reading ebooks. This is why I switched from the Sony PRS505 to the PRS600 with touch screen and ability to write/draw notes.

Since all this hype about the ipad (the last 4 weeks at least) I’ve been thinking what would I personally do to the Sony EReader to improve it.

Essentials

Add Bluetooth for file transfer, dialup, networking, etc. (Sony could still do this if the SD slot is SDIO)
Run an open operating system like a cleverly crafted Andriod on it
Add accelerometers, proximity sensors and some haptic feedback
Wireless 802.11b/g (Sony could still do this if the SD slot is SDIO)

Some would ask why not a colour screen? Well the problem is colour screens require a LCD or OLED as mentioned in the last blog post, which means less that 12hours battery life at the very best. Having over 2 weeks battery life on E-ink takes some getting use to, but I think the benefits of having e-ink certainly puts it in a different category of device and thats a good thing. Steve Jobs was trying to create a device which is in a different category but I think ended up which is too computer like in hardware but too consumer device in software.

Android would be great to have on there with a open marketplace so people can really develop for it. I don’t know if Android would work on a e-ink screen but you could imagine it wouldn’t take much to build a custom build just for E-ink screens. Bluetooth, Wifi and Accelerometers would open up a whole bunch of applications which the ipad has demonstrated. But the smaller screen would be much more mobile and friendly.

Agreed it wouldn’t be as flash but boy would it be useful and something which people might happily carry around more that this massive pad thing.

I also hope this isn’t going to start a media revolution, because if it is the publishing industry is going to put its eggs in the Apple itunes/apps store they’re crazy. This device isn’t anywhere near impressive. The only slightly impressive part is the price but I assume Apple are gambling that people will use the store to make up the difference in price. Maybe in the end the store will be the undoing of Apple, if developers move elsewhere and/or get fed up of Apple’s treatment, a sudden drop in app downloads and itunes usage could spell a lot more trouble than expected.
