The eReader

Saturday, August 7th, 2010

For a belated birthday present, my lovely wife decided to get me a nook. For the past couple of weeks I have been geeking out with my new toy. I must say that I love my nook. I have only two real complaints:

  1. You cannot download ebooks from the browser. Downloading books through the store works to perfection, but when the onboard web browser is pointed at a supported format (an epub from Gutenberg, for example, or a PDF from the Internet Archive), it chokes, saying that “Downloads are not supported in this release.” I can understand Barnes & Noble’s reluctance to allow arbitrary downloads on a specialist device, but come on. I can’t download ebooks? As an aside, it would not really surprise me if this were a tactical decision to try and get you to buy books (in this case, books that don’t exist) from the store.
  2. PDF reader oddities. I cannot say how nice it is to have PDF capabilities in the first place. I download a good deal of academic papers and this makes it a lot more convenient to drop them on the reader and read them that way as opposed to soldiering through the read on a PC or printing them off. The reflow works–kind of. The problem is that words will break down to the next line mid word. There is no attempt to hyphenate properly at all. It just breaks the line. Moreover, the next lines are not joined. So, for the most part, you get a typical line oddly broken, followed by a short line. Annoying, but not unusable. Finally, in the PDF department, certain symbols do not seem to render well. I noticed this while reading a paper by Claude Shannon. A pedestrian formula (f(x) = x) came out fx = x. This got more confusing when multivariable functions were used.
  3. The touch screen is a tad less sensitive than I would have liked. Quite usable, but this still causes some annoyances.

The big thing that this has led me to try is Calibre–an open source ebook library manager, converter, and viewer. It has been pretty nifty. One of the most awesome features is the ability to provide it with an RSS feed and have it create an ebook (ePub in my case, of course). The results are beautiful. For the blogs I read that have longer articles (or more content), I simply grab the URLs from my feed reader and drop them in Calibre. With a new baby up and about, this is wonderful, as I can read while trying to walk the little munchkin to sleep.

I really think that we are seeing the beginnings of a revolution with these eInk readers that have been coming out. Unlike some of the more enthusiastic readers who have taken to them, I do not think that they will displace print entirely. They will, however, displace casual printing. Paperbacks will go electronic. If newspapers and magazines survive the internet age, they too will go eink. Enthusiastic readers will always, I think, want their favorites bound, printed, and lovingly nestled on a bookshelf.

The ereader is not a fad–but I do think it is transient as a specialist device. The biggest reason to use an ebook reader is the eink display. Mind you, ebooks have existed for years. A dedicated reader is not a prerequisite–but it does noticeably enhance the experience. This is why people want them, as opposed to reading on a smart phone or a tablet. For the cost of the nook, I could have gotten a fancy smart phone (my carrier is offering the droid for $199.99 with a 2-year plan). But the displays are not nearly so nice.

We cannot merge them with tablets yet, either. At present, the refresh rate on eink is simply too slow for general purpose computing. The lag does not seem bad compared to turning a page. It does seem bad compared to a modern monitor’s refresh. Also, I have yet to see a color eink in the wild (though I recall reading that they are coming). This is the merge point. When eink becomes colorized with a sufficient refresh rate, ereaders will merge into the touch tablet market. It only makes sense. Why have two separate devices when one can be manufactured that will do both equally well?

Ah, well. Such musings are the last you will probably hear from me in a while. My gadget money for the next little bit has most definitely been spent.

Open Source 3D Printing

Saturday, September 26th, 2009

Recently, I was very surprised to come across some open source 3D printers. I stumbled across them looking to see how cheap one could buy a 3D printer (or “fabber”). Cheapest thing I found was about $15k. Certainly reasonable if you are a large corporation and this is for your engineers or R&D people, but not so reasonable if you are just a mad tinkerer like me. The schematics are free to download and the software is released under the GPL. Frankly, I am a lot more interested in those free schematics than in the GPL’d code, but I’ll take the whole shebang. So far, I have come across at least three open source kits to do this:

There is even the beginnings of a community at Thingiverse swapping designs for objects that can be created with these home brew fabbers. This really has my curiosity running, at this point. Obviously, the components can be purchased for a fraction of the price that you would hit buying a “cheap” 3D printer. The idea has a lot of appeal for me, personally. When I was younger, I used to design board games on notebook paper, use pen and crayons to lay out the pieces and such, then tape all of the pieces together. I could go back to the old drawing board with the ability to do something a little more elaborate. Moreover, I’ve had various ideas for things over the years that this would have been excellent for. Finally, building the thing would be a heck of a lot of fun. When it comes down to it, you would be building a manufacturing robot. How awesome is that?

I Want One

Thursday, September 24th, 2009

I just saw Mirage, an incredibly portable chess set, on Yanko Design. (http://www.yankodesign.com/2009/09/23/now-you-see-chess-now-you-dont/) Basically, it uses clip-down style pieces and a digital projector to project the board onto the table surface. The whole thing wraps up in a package clearly inspired by the iPod. So, while it will no doubt be out of my price range if and when it comes out, I still think I want one.
