Thanks to the Internet, we can to access the best minds around the world for almost free ( you still pay fo electricity & yr internet access )...

Feel very interested with this mini form size computer.

Does anyone selling it locally in Malaysia where i can order besides from their raspberry homepage?

element14 delivered my low profile micro sd card adapter from adafruit industries yesterday from US... like a boss!

If not wrong Thundermatch do sell them.

HaHa it is okay, i bought it from Element 14 already, just received the pi.

So, wanna ask you all.. what OS do you all install to get started?

Raspbian from Raspberry.org website, IINM.

got raspbian - the official one
got risc os
archlinux
puppy
sugar
and a bunch of others that you can install with berryboot
suse
openbsd
openWRT (the one that can turn it into a router)
Qton
Plan 9

these are the ones that i can think of on top of my head right now

If anyone is interested, I have an extra unit of the pi I bought from Element14, it's brand new, comes with the case and I'm happy to let it go for RM150 (shipping included)

bro... transparent casing ka? might be interested to get from you

yup the transparent one, just drop me a pm.

Recently I bought the VZTech USB strip hub and tried to cut off the backfeed by cutting off the Ground and 5V+ line and powering it off the power adapter.
It didn't work on my PC.
Even though the blue light came on it wasn't detected by the PC until I reconnected the Ground line.
Can anyone tell me why that is so?
The instructions I see online for powering hubs without backfeed was to cut off both the Ground and 5V+ line

I did not actually cut off the lines (too aggressive) but connected to the hub like in the picture below.
The hub's cable (bottom) is plugged into a dual USB port salvaged from a PC motherboard.
A cable from an external HDD (top) completes the connection to the PC.
The necessary lines GND, D+, D- are jumpered with a short wire.

Will test on RPi next.

I guess for the hub and PC to communicate via the data lines they need to have a common voltage reference point, and that's what the ground is for.

Pretty darn impressive stuffs that people can be come up with the Ras PI these days.

Raspberry Pipboy

Got my Pi working powered from hub via micro USB cable.
No backfeed as Vcc line disconnected.
Keyboard and pendrive plugged into hub.
Running RaspBMC with GPIO IR receiver and remote from cheap China DVD player.
Successfully networked to internet the other day.
Was able to stream Youtube smoothly too at 480P (haven't tried higher yet)

I would like to ask, can i use my Samsung travel adapter charger as a power input for my Raspberry Pi?

since it is written there output 5 volt also

Nowdays, all USB chargers are 5V...

See the Ampere rating... mobile charger are usually 1A ( or 1000mA ) or 2A ( 2000mA ) for tablets.. RPi needs like 1500-2000mA bcos the RPi already taken up like 700mA... when you plug in other sutff like keyboard, USB hard disk, USB Wifi adapter, other USB accessories... it will need to draw power from the adapter...

If you do not plug anything to the USB port, then it should be okay...

I might have missed something important here... what's wrong with powering the RPi from the backfeed ??

It bypasses the input polyfuse, so you might fry your pie if there's any kind of power surge.

I used two Samsung travel adapter both 5V 700mA
One worked flawlessly the other boots but won't power my usb keyboard or pendrive.
The working one came from Galaxy Mini measures 4.52V at TP1/TP2
The other one comes from an S2 measures 5.28V at TP1/TP2
I'm guessing the S2 travel adapter doesn't provide enough current?

I'm now using 2A power adapter taken from media player.
Reads 5.13V at TP1/TP2

The VZTech adapter outputs 5.9V at the jack and fluctuates all over the place at the Pi TP.
Keeps rebooting.

What yu_wang said.

Power surge on the 5V USB power... are you sure ??

This is not 220V mains...

Unless u r using the 1st revision....

As of Model B Revision 1.0 + ECN0001 onwards, the polyfused WAS removed ...

USB Output Power

The resetable fuses protecting the USB outputs have been removed. This feature was implemented on some later revision 1.0 PCBs by replacing the fuses with links; revision 2.0 permanently implements this modification. It is now possible to reliably power the RPI from a USB hub that back feeds power, but it is important that the chosen hub cannot supply more than 2.5A under fault conditions

So the USB power adapter you choose is important too....
