The Paper Renaissance

June 18th, 2007

Quentin Stafford-Fraser (introduced earlier) recently spoke at the 2007 GOVIS conference.

His first talk, ‘Changing the Face of the PC’, tells the story of the creation of Ndiyo, DisplayLink, and Cambridge Visual Networks, the technologies and motivations behind them, and some thoughts about the future.

Quentin and Martin King are founders of DisplayLink (formerly Newnham Research) as well as Exbiblio.

The second talk was focused on Exbiblio—our vision, technology, company, values, and more. Please have a look, to see who we are, what we are doing, and how we intend to do it:

Rosencrantz Image Sensor Driver

May 23rd, 2007

Elf's GnomeWe’ve been having trouble getting the image sensor data through to the main memory on the Rosencrantz form factor board, but today, Oscar, from Synapse, figured it out.

Getting the image processing unit (IPU) configuration right in the iMX31 has been a difficult task, and as of yesterday, we were getting images through, but only half an image frame’s worth of data per frame. Today, Oscar triumphantly sent us a picture of a gnome taken with the form factor board.

This takes a major concern off our shoulders.

Software Development Progress

April 17th, 2007

Life LibraryOn the software side, we’ve also undergone quite a bit of evolution.
In its previous incarnation, the Exbiblio system comprised components written using a variety of computer languages and technologies, such as C, C++, Objective-C, C#, AppleScript, Visual Basic for Applications, and Java (many or all of which will resurface over time). We were trying to leverage each contributor to their fullest by keeping them working in their most familiar environment, at the cost of more complex communication between the components. We were also trying to build in a lot of flexibility by having separate processes communicating with each other, at the cost of simple installation and maintenance. Read the rest of this entry »

Hardware Development Progress

April 13th, 2007

Non-Form Factor Board & Form-Factor Board I feel a bit intimidated by the idea of presenting what we’ve done since we last posted updates on the software and hardware development. I think I’ll let the overview slip a bit, and get started with a few recent tidbits.
We just reached some very exciting milestones on the hardware side, in that we got our first form-factor boards in, as well as early samples of the case. The boards don’t yet have the components placed on them, but they will be “stuffed” shortly. Read the rest of this entry »

NYT Gets It

April 13th, 2007

“Until now, in most parts of the world, Web surfing has been separate from everyday activities like riding the train, watching television and driving. But the new technology may erode that distinction.

““You’ve picked up this product, and you don’t want to go back to your PC,” said Tim Kindberg, a senior research at the Bristol, England, lab of Hewlett-Packard. “Or you’re outside this building, and you want more information. We call it the ‘physical hyperlink.’ ””

So read some quotes from, well, let’s try what we’re calling the Exbiblio Eureka: 6 words in sequence are a URL (in this case 8 works slightly better):

A a search on Google reveals that the article appeared in

The New York Times
The Orlando Sentinel
The Denver Post
Debit Card News
Signal Lake

What’s so exciting about Exbiblio and the oPen™, is that you don’t need the bar codes. You can do the same thing without them, using the Eureka and a great capturing device.
