Hacking Esquire's E-ink Cover

morcheeba Re:Just got one (205 comments)

My point is that you don't get free energy... you could eliminate those extra batteries, but to get the same life, you'd need to replace them with a single larger battery. That single larger battery probably wouldn't fit in the cover as well as the lots of little ones.

An example: The CR2016 batteries used are 90mAH, 1.6 mm thick, and 20 mm diameter. Replacing this with a DC/DC converter (at a very generous 80% efficiency - at currents this low, the power taken by the generator is significant - the real efficiency would probably be in the 40-50% range) would be a single 675 mAH battery. That's a CR2450 battery -- 5 mm thick (3x thicker) and 24mm in diameter.

Pricewise, CR2016's are $0.18 each, qty 5000 (Esquire ordered 1.4 million batteries). I didn't find bulk 2450's, so I compared the same manufacturer from the same vendor - the price was 2.66x the cost of the 2016 -- so, I'd guess $0.48. The savings is 6*0.18 - 0.48 = $0.60. At 40% efficiency (two 2450's), the savings is $0.12 -- minus, of course, the cost of the converter, which is non-trivial. You need the driver chip (usually not cheap) and a pair of capacitors (high quality, or else you'll get EMI).

CVS Camcorder usably hacked

morcheeba morcheeba writes  |  more than 9 years ago

Here's my rejected slashdot submission:

2005-08-03 06:16:55 CVS Disposable Camcorder USB-Only Hack (Hardware,Hardware Hacking) (rejected)

The CVS Disposable Camcorder (mentioned about a month ago) has now been usably hacked so that videos can be downloaded over USB - no need to desolder the flash memory. Finally, some healthy free-market competition to CVS's expensive development service, just like in the analog world. Last week, dakotamod and mconsidine were able to coax mystery responses back from the camera. I found what looked like a set of challenge & response packets stored in memory, and then traced the firmware until I found where they was accessed. I thought I had found a locking mechanism, but wasn't sure until I realized that it only allowed the commands dakotamod & mconsidine had found were accessible... we were on to something! I figured out what the commands did and how to use them to how to unlock the camera. The community took it from there... daBass figured out the USB command to download the most recent video, and Corscaria and BillW quickly released tools. When unlocked, it seems that many standard windows drivers can be used with slight tweaks, including enabling full VGA resolution recording @ reduced frame rate (as opposed to the 1/4 VGA default).

There are now a lot more sample videos. And, lastly, this removable memory hack is awesome.

I sent the same text (plus more) to Makezine, where it was published, and then boing boing picked it up.

Book Reviews: Purely Functional Data Structures Programming
Posted by timothy in The Mysterious Future!
from the raw-function-baby dept.
andrew cooke writes "A while ago I read the comments following a Slashdot book review. Someone had posted a request for books that covered a wider range of languages than Java, C, Python, etc. Well, I thought, why not review Okasaki's Purely Functional Data Structures? It's a classic from the underworld of functional programming - recognised as the standard reference, yet clear enough to work as an introduction to the subject for anyone with a basic functional programming background. Of course, some readers won't know what functional programming is, or what is special about pure data structures. So I hope that this review can also serve as something of an introduction to the languages that I (a software engineer paid to work with Java, C, Python, etc) choose to use in my spare time, just for the joy of coding." Read on for the rest; even if you're not planning to give up C or Perl, there are links here worth exploring.

There wasn't any more to "read on", so I suspect it'll show up in its complete form later.

Intel introduces 64-bit x86, repositions Itanic

morcheeba morcheeba writes  |  more than 10 years ago

It's official now: Intel announced 64-bit x86 chips, and has repositioned the 64-bit Itanium as a database processor. From the article: "Intel will deliver in the middle of the year Nacona, a 64-bit Pentium 4 Xeon processor geared for two-way servers. Later in the year, it will release a 64-bit version of Prescott for high-end desktops and workstations using a single processor. Next year, Intel will release multiprocessor-capable version of its 64-bit Xeon."
Microsoft's beta version of its 64-bit operating system will support both the new Intel chips and AMD's 64-bit Opteron and Athlon CPUs, though it's not clear if Intel is using the same x86-64 extensions AMD does.

Intel may introduce a new memory interface

morcheeba morcheeba writes  |  more than 10 years ago

EE Times is reporting that Intel may be pushing a new kind of RAM interface to compete with existing DDR and RDRAM. At 2 Gbit/sec per wire, this is about twice the speed of current RDRAM and four times the speed of DDR SDRAM. But, more interestingly, this is a point-to-point architecture - unlike the traditional bus architecture, when you add more memory modules you can get more bandwidth. Also notable is that simultaneous bi-directional communications happens over a single wire. Infineon and Samsung have made test chips, and results are to be released at the International Solid State Circuits Conference today.

Disposable Digital Camera now connects to home computers

morcheeba morcheeba writes  |  more than 10 years ago

The protocol for the $11 disposable digital camera previously mentioned on Slashdot has been reverse engineered. You can build a $7 USB cable and add Mac, Linux, or Windows software, and you'll have a 1.2 megapixel camera you don't have to worry about. Picture quality isn't that great, but it's cheap enough to experiment with. It turns out that the camera's interface is similar to others supported by gphoto2, except that a simple hash function enables data transfers. No encryption was used.

electrokinetic microchannel battery

morcheeba morcheeba writes  |  more than 10 years ago

U of Alberta professors Larry Kostiuk and Daniel Kwok have developed a prototype electrokinetic microchannel battery that converts hydrostatic pressure directly into electrical current. It uses just water under pressure -- no chemical reactions. Unlike turbines, there are no moving parts. The prototype combined sub-nanoamp electrical output from 500,000 microfluidic channels to generate microamps of power. The prototype yielded 3.8 microwatts/cm3.

Belarc Software Key vulnerability

morcheeba morcheeba writes  |  more than 11 years ago

GrepLaw is reporting an amazing security hole when Belarc Advisor is run improperly. The software is designed to give a complete profile of your system (including usernames, mounted directories, hardware and software installed - keys included!) ... if it leaks onto the web, google might index it for all to see. So far, though, it looks like most of these pages are people showing off their rigs. It is kindof neat that U of texas has an ALVA braille display to go with their flat-screen monitor.

Terminator 2 DVD - super region coded?

morcheeba morcheeba writes  |  more than 11 years ago

According to the inquirer, the new high definition 1080p Terminator 2 DVD encoded with Microsoft's WMV 9 Pro goes beyond normal DVD region-coding: "it checks if you are in the USA or Canada, possibly by using IP addresses, and if you're not, you're terminated." Among WMV 9's extensive security features is the ability to "enable integration into existing business models" - can anyone confirm they've integrated into the DVDCCA's existing business model?

AOL kills puppies

morcheeba morcheeba writes  |  more than 11 years ago

I saw this link on politechbot - wow, AOL kills little tiny puppies!! All just because they don't allow links in email signatures. You'd think they wouldn't care about the content of emails (yes, a sig line is content - you could just as easily add it in your self and it's indistinguisable from the body), and if they wanted to enforce this policy, they could just pare links out of the sig lines. But what if your email reader sees a url-looking thing that isn't a link and automatically makes a link for you? is tat.to now forbidden (it goes to a web page)?

Hong Kong gov spams 6M phones to avert SARS panic

morcheeba morcheeba writes  |  more than 11 years ago

To avert a panic over SARS, Hong Kong governnment officials have spammed 6 million phones with an SMS message saying Hong Kong isn't an infected area. The city of 6.8 million residents has had 16 deaths, more than 700 sick, and hundreds placed under quarantine. The spam was allegedly in response to a hoax website, not in response news reports of the mysterious killer.

Benetton to embed RFID in its core brand of clothes

morcheeba morcheeba writes  |  more than 11 years ago

EETimes is reporting that Benetton will be embedding a Philips RFID chip into the label of every new garment bearing the name of Benetton's core clothing brand, Sisley. The 15 million chips expected sold in 2003 will allow monitoring of garments from production to shipping, shelves and dressing rooms. The I.CODE chip (tech info) used in Benetton's labels includes 1,024 bits of EEPROM, and operates at a distance of up to 1.5 meters. RFIDs look like they would be extremely uncomfortable in some Sisley clothes.

The above story made slashdot's front page, but it was listed as a 'rejected' story, so you won't see it in my stats...

RIAA: warning labels not necessary because most kids steal music.

In a New York Times article on proposed more descriptive "parental advisory" warnings, Hilary Rosen (CEO of the RIAA) stated that a new warning system was unnecessary because a large number of adolescents and teenagers no longer bought their music in stores. The article says that kids simply go to the Internet and download it, and that Hillary said most parents do not know how to access these sites. "There is no labeling on the Internet," Ms. Rosen said. "If anyone is going to express concern that's what it should be about."

So, if parents learn to use the internet, then they'll start labelling music better? Or, is she saying that you should trust 'music pirates' with your kids upbringing instead of the music publishers? Clever tactic - making music labelling a piracy issue.

HIV crosses species barrier... into Muppets

morcheeba morcheeba writes  |  more than 12 years ago

The Washington Post is reporting that a new HIV-positive character will be introduced on Takalani Sesame, the South African version of Sesame Street. How HIV was contracted is still under discussion, but it likely involved either a cross-species blood transfusion, or transmission through childbirth (meaning that the new character is a Muppet-human hybrid). The show will have no discussion of unsafe Human/Muppet sexual practices or intravenous drug use, the two foremost means of transmission.

Satellite radio wants 802.11b/Bluetooth emissions restricts

morcheeba morcheeba writes  |  more than 12 years ago

Commsdesign is reporting that Sirius Satellite Radio is petitioning the FCC for stricter emission requirements, which could cause serious problems with license-exempt services in the 2.45GHz band such as 802.11b and Bluetooth. Even though Sirius knew what the acceptable levels of pollution were in its band (2.320-2.345 GHz), they now want these lowered. Motorola's response indicates that vehicle ignition systems may be the biggest contributor of noise. Intersil (a maker of 802.11b chipsets) had an even more scathing response, blasting Sirius for a poor design (link margin only 6.7dB) and even claims that the new restrictions would be below the thermal noise floor. See also this netsumbler post and this 802.11b weblog.
