Hooray! Nikon D300 and D3 are out.

depreview.com published two articles today to Nikon D300 and D3. The status of D200 might become embarrassing. But Nikon will take some marketing strategy to handle this. I am ready to throw my old D100 away now, and hope We can get a good deal for D200 before Xmas :D

Here are the photos and citation words from depreview.com



Nikon announced the new DX format D300 which also features a 12 megapixel CMOS sensor, 14-bit A/D conversion, EXPEED image processor, sensitivity up to ISO 6400 (with boost), the new CAM3500DX AF sensor (51 point), HDMI video output, UDMA CF support and last but not least the super-impressive 3.0" 922,000 pixel LCD monitor with Live View.

Nikon has today lifted the covers on their first full-frame digital SLR, the new 12.1 megapixel D3. The D3 is all about speed and sensitivity, twelve megapixels on a big CMOS chip means large photosites (8.45 µm pitch to be precise) and that adds up to base sensitivity of ISO 200 to 6400 with an additional two stop boost over that (up to ISO 25600).

Sexy Bluetooth Keyboard and Mouse under Linux

I recently bought a brand new DELL Bluetooth Keyboard and Mouse Bundle (they are actually produced by Logitech) . Here is the picture of this beauty:



The reason of this purchase was I couldn't find my mouse shipped from Germany and my keyboard is old and I was annoyed by those wires and cables and I saw the SALE by DELL. La la la...

When I got it and tried it under windows, I was a bit surprised by its handy functionalities and reliabilities. Em at least, it's installation under Windows was easy and straightforward. Then I tried to use it to drive my lovely Debian system, however I had no lucky this time. The set up of this BT keyboard and mouse was a bit funky and I spent a whole night to work it out. And now it's the time to share my experience.

• Step 1: Setup Kernel

Networking --->

<*> Bluetooth subsystem support  --->--- Bluetooth subsystem support

   L2CAP protocol support

   SCO links support

   RFCOMM protocol support

[*]     RFCOMM TTY support

   BNEP protocol support

[*]     Multicast filter support

[*]     Protocol filter support

   HIDP protocol support

Bluetooth device drivers  --->

 HCI USB driver

[*]   SCO (voice) support

 HCI UART driver

[*]   UART (H4) protocol support

[*]   BCSP protocol support

[*]   Transmit CRC with every BCSP packet

 HCI BCM203x USB driver

 HCI BPA10x USB driver

 HCI BlueFRITZ! USB driver

(The four drivers below are for PCMCIA Bluetooth devices and will only how up if you have also selected PCMCIA support in your kernel.)

 HCI DTL1 (PC Card) driver

 HCI BT3C (PC Card) driver

 HCI BlueCard (PC Card) driver

 HCI UART (PC Card) device driver

(The driver below is intended for HCI Emulation software.)

 HCI VHCI (Virtual HCI device) driver

(Move back three levels to Device Drives and then check if USB is nabled. This is required if you use a Bluetooth dongle, which are mostly USB based.)

USB support  --->

<*> Support for Host-side USB

--- USB Host Controller Drivers

 EHCI HCD (USB 2.0) support

[ ]   Full speed ISO transactions (EXPERIMENTAL)

[ ]   Root Hub Transaction Translators (EXPERIMENTAL)

<*> OHCI HCD support

<*> UHCI HCD (most Intel and VIA) support

< > SL811HS HCD support

Build the kernel and then install it

• Step 2: Bluez-Utils

Install the Bluz-Utils by`ap-get install Bluz-Utils`

• Step3: Configuration (very important)

Now it's the tricky time. The key point is this BT Keyboard and Mouse can not be used as hci, so we need to use hid instead.
A) Find out the MAC address of them by `hcitool scan` or `hidd --search`. If there's no results, then press the sync button on the bottom of the devices, and try again. The result looks like:

# hcitool scan
Scanning ...
       00:0A:0B:0C:0D:0E	DELL BT Mouse

B) Turn off HID2HCI at "/etc/default/bluetooth" : change the value of HID2HCI_ENABLED to 0.

HID2HCI_ENABLED = 0;

C) Enable HID daemon and set the start up options at "/etc/default/bluetooth" :

HIDD_ENABLED=1

# The MAC address here is just a fake example

HIDD_OPTIONS="--master -i 00:0A:0B:0C:0D:0E -i 00:01:02:03:04:05 --server"

Reboot and Cheers!
There are some other softwares for gnome, which can let you setup all the functional buttons, such as volume turner. Very fancy and SEXY.
