i have ordered twice during this offer, they wont deduct the 20 straight away in the website. normally they will show the free shipping offer in the invoice emailed to you.

if the item is still processing, just email them and tell that you forgot to put the free freight special instruction. that is what i did when i first ordered my pi and they helped to change it to free freight for me

Hey C-Fu and other electronic gurus,

I have some question. For resistor with rating 100ohm 3 watt.(same thing for 330ohm 1watt.)

What does the 1 watt mean? The resistor it self draws 1 watt?

If connected to a 12V sla battery. How many V drop does it cause?


Thanks so much,
Skyward

No,the watt is the power rating of the resistor.its the amount Of power the resistor can take.exceeding the power rating will cause the resistor to blow. 3 watt is a lot I think

Guess what, I just received an email for the acknowledgement of order and it says amount charged to card is RM111!

Haha, I'm assuming they deducted the shipping fee (RM20) in the acknowledgement of order but didn't show it during the order confirmation when checking out at element14's website. And nope, I didn't put in free freight either as a special instruction.

And, my ETA is tomorrow! Really quick service, order yesterday night and receive a working day after from SG.

true! they should have just show the free delivery at the website, easier. lol. yeap they are damn fast, i got my Rpi and HDMI cable the following day.

now just waiting for the clear case enclosure to arrive tomorrow! read the reviews that this case is one the best fit for the Rpi . they have just re-stocked the case 14++ left in SG @ RM28.70

It looks really nice. I also prefer the clear one over the white or black one.
Will try the Punnet cardboard case for a while first or maybe DIY one out from an old cassette tape like what C-Fu did.

Speaking of cases for the RPi, this one called the Pi Flavours really caught my attention!



And it comes in different colours too!

hmmm... maybe you put under delivery note? i made that mistake once... luckily haven't paid yet that time

I asked them if their promo is valid for out of stock items, and here's their reply:

Wow..I just notice,u gonna power your pi with lead battery??

this guy made a better layout based on the punnet cardboard case. he tried the punnet case and there were some parts that do not fit nicely, so he improved the layout here http://www.raspberrypi.org/phpBB3/viewtopic.php?f=40&t=6500 just remember to print in actual size.

eh, even c-fu bought the clear one

damn, pi flavours eh, damn nice. definitely a premium case, 22 euro.

the sealed lead acid is for cree xpe leds


I have some other problem powering the pi directly via usb hub.

So I have a dell x50v, dc adapter rated for 5.4v. zero load it measures 5.6v. So I tried to put a shoctty diode to hopefully give a forward voltage of 5.3v. However, it does not seems to work with my usb hub. I soldered in series to the usb hub input. Across the diode, indeed the voltage measured 5.3v, but if I include the usb hub into the measurement it shoots up to 5.5v...


I wonder if the polyfuse on the usb hub got blown... since I measured the usb ports voltage and they come up to 100mv+/-




/newbie - I just blown my first diode. spectacular poofff

Haha,I'm still planing on a 2A USB hub driven by 9v adapter..parts are shipping in with the Pi..why use schottky diode? Try using a 7805 voltage regulator,5v

7805 need more then 6 dcV to provide stable 5Vdc 2amp, or so I was told and read.


In your case if you have a 9v adapter, down converting it using the 7805 should be ok.

Use LDO voltage regulator then,their range of input voltage are more flexible,even below 5v can drive it

Thanks for the link. Lol, I actually printed out a few layouts of cardboard cases for the RPi already.

And yeap, the Pi Flavours is really nice (and premium). It's got stainless steel construction with rubber feet. Very good quality product IMO.

Hmm, can you suggest a specific part from my.element14.com so I can place the order without making mistake.(I accidentally bought smd, and also some huge resistors...)

Thanks

After sorting out,I think u can try this,

http://my.element14.com/micrel-semiconduct...d-5v/dp/1556712


Output current 1.25A
Minimum input voltage 4.3v
Max input voltage 26v

But it cost 8 bucks

So now since we can't purchase from element14, do we need to purchase directly from reseller? Can't find it listed in Thundermatch's website even tho they are listed by element14

U can still purchase from element14,just click "buniness" instead of "personal",it will direct u to element14 order page like old times

welp, thanks mate!
