Linux:Bluetooth – Motorola S305 – way better sound or stereo :)

Re: Motorola S305 bluetooth headset

Go to System->Preferences and open the Sound panel. Select the "Hardware" tab and click on "Motorola S305", then you will see the choices for in the Profile menu at the bottom. In the Profile menu you can choose between HSP/HFP (telephony) or A2DP (stereo headphones). I discovered this by accident. I kept looking in the Bluetooth preferences but now that I see that setting here it makes sense.




Raspberry Pi: mount flash disks at boot

Now that I got a little time to work on my Raspberry Pi, I decided to have 2 2GB flash drives mounted at boot to save some write cycles on the SD card:

After a few failed times, I googled for a while and the important bit is the 6th field in your /etc/fstab file. Here's mine:


[root@pi ~]# cat /etc/fstab
# /etc/fstab: static file system information
# <file system>        <dir>         <type>    <options>          <dump> <pass>
devpts                 /dev/pts      devpts    defaults            0      0
shm                    /dev/shm      tmpfs     nodev,nosuid        0      0
/dev/mmcblk0p1  /boot           vfat    defaults        0       0

/dev/sda1       /var       ext4    defaults          0       2
/dev/sda2       /data      ext4    defaults          0       2
/dev/sda3       /tmp       ext4    defaults          0       2
/dev/sdb1       /home      ext4    defaults          0       2


The "2" in the 6th field tells the kernel to wait for the drive to be available before trying to mount it.

Here's the "mount" command output:

/dev/mmcblk0p1 on /boot type vfat (rw,relatime,fmask=0022,dmask=0022,codepage=cp437,iocharset=ascii,shortname=mixed,errors=remount-ro)
/dev/sdb1 on /home type ext4 (rw,relatime,user_xattr,barrier=1,data=ordered)
/dev/sda2 on /data type ext4 (rw,relatime,user_xattr,barrier=1,data=ordered)
/dev/sda3 on /tmp type ext4 (rw,relatime,user_xattr,barrier=1,data=ordered)
/dev/sda1 on /var type ext4 (rw,relatime,user_xattr,barrier=1,data=ordered)




WRT160n v3 flawed 3.0.02 firmware: DHCP can’t keep track of leases: IP conflicts all over the place

Very often here at the office we have loss of internet connection even though it seems the local network connection never goes down.

Besides losing the internet connection, my laptop frequently displays a message saying there’s an IP conflict, which doesn’t make much sense as the only DHCP server running on our network is the router’s

This screen shows that my computer has IP address and it’s not listed under DHCP client list. Anyone care to help understand why?

Update 2010-11-11:  I decided to start using DD-WRT on this router.

Firmware: Firmware: DD-WRT v24-sp2 (08/07/10) mini
Time: 14:54:41 up 2 days, 5:27, load average: 0.13, 0.11, 0.05
So far, no more of those crazy problems the default firmware has. You may want to do yourself a favor and check if your router is supported.

Trying my GSA-T20L optical drive with MCE usb 2.0 enclosure for the superdrive

After purchasing and using the MCE optibay on my white macbook 13″, I got really curious as it that would work for any regular laptop PC….

Having not asked any of the manufacturers involved, I put my brain to work and wouldn’t make any sense for Apple to create a totally different connector for its Super Drive (as it would shrink its market and make it worse/harder for consumers to get replacement parts); and would make even less sense for MCE to develop something that would not follow any standard.

People can always say that mixing parts of different manufactures is dangerous (that seems to be some Apple certified technician’s minds by the way); and there will be those asking why I would take a chance of frying stuff when Asus and other laptop PC manufacturers have models with raid support.

Well, I happen to be curious and I don’t have money to get one of those, so….

Again I don’t have a lot of spare money… so for now I just tried hooking up the optical drive from my Asus G1s to the MCE usb 2.0 enclosure that came together when I bought my MCE Optibay. So far my experiment works….

As soon as I finish transferring all my files to an external HD I will post more pictures and an update to this post. Stay tuned.
