FireWire Port Failures Subject of WiebeTech White Paper

WiebeTech has published a white paper, FireWire Port Failures in Host Computers and Peripheral Devices, that provides useful information on the causes and prevention of FireWire port failures, especially in host computers.

"We have seen much interest on the part of FireWire users regarding this subject as judged by recent comments on industry websites. We think users will be interested in reading our analysis of the cause and prevention of port failures," said James Wiebe, CEO of WiebeTech.

Silicon and Graphite, a Materials Match Made in Battery Heaven

Researchers at the Department of Energy's Sandia National Laboratories in Livermore, CA, have developed a new class of composite anode materials composed of silicon and graphite that may double the energy storage capacities currently possessed by graphite anodes, potentially leading to rechargeable lithium-ion batteries with more power, longer life, and smaller sizes.

"Manufacturers of electric automobiles, laptop computers, cell phones, power tools, and other hybrid microsystems will likely all benefit from this kind of technology," said Scott Vaupen of Sandia/California's Business Development Department. Vaupen said Sandia is actively seeking collaborators to further develop the technology for eventual licensing and commercialization.

The marriage of silicon and graphite may improve the specific capabilities of commercial graphite anode materials up to 400 percent, said Jim Wang, Manager of the Analytical Materials Science Department at Sandia.

Wang said researchers have been vexed for years by the capacity limits associated with traditional lithium battery anodes. Sandia turned to silicon, which offers more than 10 times the lithium capacity potential of graphite, but is hampered itself by a rapid capacity loss during the battery cycling phase. When small particles of silicon are combined within a graphite matrix, however, the large capacities are retained.

Sandia researchers acknowledge that some potential vulnerabilities exist with the new material. The complete elimination of fading of long-term cycling capacity in the silicon-based electrodes, Roberts said, may not be possible, though it can likely be minimized by the design of the carbon-silicon composite microstructure.

802.11b PC Card on a PowerBook 5300

A PowerBook 5300 owner sent xlr8yourmac.com a long email with comments and links on using a 802.11b PC Card (Orinoco gold card) with a nearly eight-year-old PowerBook and Mac OS 8.1 and 8.6.

How to Find Your iBook's Serial Number

Apple has posted a Knowledge Base article explaining how to find the serial number on each model of iBook computer - but here's a shortcut if you're running OS X: Open "About This Mac" and click on where it says "Version 10.x.x."

The version of the OS X you're using will appear.

Click on that number, and the the number OS X build you're using will be displayed.

Now, click again on the build number, and your iBook's serial number will appear (this works with most Macs about three years old or newer, but not with older units).

To find the serial number located on the computer:

iBook, iBook (FireWire)iBook Serial Number

The serial number for these iBook Serial NumberiBook models is located in the battery bay.

  1. If the computer is on, shut down it down and close the lid.
  2. Turn the computer over so you are looking at the battery door.
  3. Remove the battery door.
  4. The serial number is located near the bottom edge of the battery door.
iBook (Dual USB), iBook (Late 2001), iBook (14.1 LCD), iBook (16 VRAM), iBook (14.1 LCD 16 VRAM), iBook (Opaque 16 VRAM), iBook (32 VRAM), and iBook (14.1 LCD 32 VRAM)

For these models, the serial number iBook Serial Numbermay be located in one or both of two locations, under the keyboard or in the battery bay.

Under the keyboard:

  1. If the computer is on, shut it down and leave the lid open.
  2. Remove the computer's keyboard. F
  3. The serial number and Ethernet ID (also called a MAC address) are located underneath the keyboard on the upper ledge. The Ethernet ID is located on the left side of the ledge, and the serial number is to the right.

In the battery bay:

  1. If the computer is on, shut it down and close the lid.
  2. Turn the computer over so you are looking at the battery door.
  3. Remove the battery door.
  4. The serial number is located on the bottom of the bay.

Brenthaven Mobile Urban Case

The Mobile Urban is a professional looking wheeled case with good carrying capacity and maximum protection from vibration and jarring. The Mobile Urban has a fully extended height of 39".

Features:

  1. The invisible telescopic handle hides when not in use and is tall enough for someone over six feet tall to use - with a fully extended height of 39-3/4-inches.
  2. The softdrive wheel suspension system is a pair of skate wheels that minimize the damaging vibration caused by sidewalk seams and other obstructions you roll over.
  3. The vertically oriented Mobile Urban rolls down the aisle of a commercial aircraft without catching on the seats - something that can't be said for horizontal wheelies.

The Brenthaven computer protection sleeve protects the computer body using an ultra-light, corrugated polyethylene shell. This rigid shell, when combined with a lower bed of proprietary high-density foam, provides the heart of Brenthaven's family of award winning sleeves.

Stage 1 Protection:

Proprietary High-density Foam

Upon initial impact, the computer begins to sink into the bed of high-density foam at bottom of the sleeve. Due to the distinguishing nature of this materials, impact immediately begins to dissipate.

Stage 2 Protection:

Frame Compression

The shell is constructed using vertical corrugated plastic flutes that are lightweight while providing an extreme amount of strength and great energy absorption properties. While the bed of high-density foam is absorbing the shock impact, the rigid walls also begin to flex providing the second level of unmatched computer protection. This rigid wall system also prevents sharp objects from puncturing through the sleeve helping reduce the risk of side impact damage.

The Mobile Urban sells for $379

WiebeTech Introduces USB 2.0/FireWire Combo Version of MicroGB+ Pocket Drive

WiebeTech announces MicroGB+™ Combo, featuring both FireWire and USB 2.0 ports. The compact, rugged case made of anodized aluminum easily fits into a pocket.

Bargain 'Books

There are two different versions of WallStreet running at 233 MHz, the cacheless MainStreet version and the later Series II with a level 2 cache. It's not always possible to determine from the vendor's listing which is being offered, so we've included links within this paragraph to the two models. The same goes for the PowerBook G4/667 (Gigabit Ethernet/2001) and G4/667 (DVI).
