Bought mine at Sri Computer Low Yat.
RM23
Comes with 5V 1.0A adapter.

I'm thinking of cutting off the 5V line to prevent backfeed.
Will that stop the hub completely like when you turn off the side switch?

How about putting a diode across the cut line to prevent backfeed and yet to use the hub with or without the power adapter?

I doubt it would cause any issue.. as long the diode supports the power rating..

Just received a call from element14 that my order for black casings are out of stock, had to swap for whites. Should receive them by tomorrow.

Put your office address as invoice address, delivery to house address. Everytime I order they call to confirm. GDex wil also call to confirm.

Thanks guys. Putting my company address as invoice and my home address as delivery does the trick. Now its shipping to me and will get RPi soon.

Best regards,

I just received my 2.5A power adapter from ebay. the power out plug is bigger than the normal 1/2A 5v adapter/hub (the small one).

i understand that by modifying the plug by using a small one, and sticking it into the hub will blow the hub (and possibly every usb adapter that are connected to the hub). so my question is how to modify the hub to accept 2.5A power as well as protect usb devices inserted into the hub.

Will it?
As I understand electricity, having extra amperes won't blow your hub or devices attached to it unless one of the device draws excessive current.
However having a higher voltage certainly will.
Also this hub is suppose to have over-current protection to prevent overload though I don't know if it at port level or for the whole hub or by how much.
Anybody care to experiment? rolleyes.gif
Report back here please...

Over current protection are resettable polyfuse/ PTC that will break the circuit temporary when too much current flowing thru it...

With so many types of USB hub at different price level/ design/made in China, it is hard to determine which ones have over-current protection at port or device or any protection at all..

See this example for the PTC
( http://dangerousprototypes.com/docs/ATX_Br...design_overview )

The standard USB current was suppose to be 500mA (0.5A) per port but these days using as a charger, some USB power supply will spill out 2A/1A via the USB port...

Except the Apple computers (not sure about the latest laptops), most standard USB port only supply 500mA via its USB port...

So the current protection question, should it be 500mA or 2000mA ??

A picture of the mentioned plug will tell a thousand words...

hey, new here, saw Raspberry Pi can do a lot of things. Feel like buy one and tinker with it and learn some techie knowledge.

just want to ask you guys if you can help me understand the difference
http://my.element14.com/jsp/bespoke/bespok...equestid=249225

whats the difference between the SD card provided?
MEMORY, SDCARD, RASPBERRY PI, 4GB
MEMORY, 4GB, SDHC, ULTRA

both same capacity, just one preinstalled the OS in it but is halved.

Once clarified will order the lot and learn how to tinker about biggrin.gif

Thanks, do let me know what else I need aside from the board, HDMI screen/ cable, ethernet, USB keyboard/ mouse
