Yah a K16 on a Ras-Pi could do the trick.

To my understanding there is not many data centre's as well and the internet infrastructure is abit lacking at least in terms of speed. Then again I do not rate Australia's internet that crash hot either. (Hurry up with the NBN, the doctor said I need more fibre in my diet)

I would recommend leaving the unit at the school as the problems/issues created can be seen first hand and stimulate ideas that can later benefit a community.

For example it might spark an interest within a student to develop an efficient form of electricity generation because you have then exposed them the power issue needed to create a mining farm but later in life use their creative ideas in rural (kumpung) communities.

Exposing your students to bitcoin is awesome and for an approximately $160 its still very competitive.

One of the main problems I would of thought why there are no GPU mining rigs in Indonesia would be the limitation of how much electricity is delivered to a house. I do remember my aunty's house only having a maximum of 4kw.

interested however dont have any chips

Let me congratulate you for taking the initiative for starting and Aussie Group Buy

I don't know if many Aussies know about bitcoin?

I am promoting it to all my clients, mind you the lecturing can be exhausting.

Looking at it from a tight arse perspective, wouldn't it make more sense to do a group buy from BFL? considering that their 5GH machine are nearly in production and the cost is not that much more negligible compared to the 300MH Erupter? The money saved from shipping could make the BFL group buy a more viable choice and then theres the NO minimum order to add to that.

Also on the same tight arse note, for 2 bitcoins at the current price of $119USD you could almost purchase a 7870 delivering 450MH and the only difference would be that the Erupter would use far less power, however considering you could use your card to mine scrypt based coins or eventually use it as a normal graphics card once again, I would consider it better value to purchase a graphics card.

I would understand buying a Erupter for novelty reason but economically, does not seem like a wise choice.

Personally if I had acccess to an engineer I personally like to see an avalon chip group buy here in Australia

I am running win 7 64bit cgminer 2.11.4 catalyst 13.1
The problem with my 7970 at 900/1350  it goes over 80c degrees
It is a XFX DD card

The 7870 is a Gigabyte OC edition again I am pretty sure with this one its going to take alot of mucking around to find the g spot

"intensity" : "13,12",
"vectors" : "1,1",
"worksize" : "256,256",
"kernel" : "scrypt,scrypt",
"lookup-gap" : "2,2",
"thread-concurrency" : "8192,8192",
"shaders" : "0,0",

Just posting up some of my tests for Litecoin mining

7970 w 256 i 13 tc 8192  

1000/1660=701
950/1580=665
920/1375=645
900/1350=632
840/1250=590
800/950=563

As you can see my sweet spot with my 7970 is around 0.6 and I can increase my clock speed and memory speed based upon that and can break the 700k/h mark.

However with my 7870, its a totally different ball game

7870 w 256 i 12 tc 8192

1200/1500=410
1200/1400=400
1200/1300=352
1200/1250=405
1200/1200=400
1200/1150=365
1200/1100=358
1200/1050=330

1100/1300=366
1100/1200=375
1100/1100=365
1100/1000=373
1100/900=343

scrap that after restarting cgminer, I am getting different results for each clock.

Same here
luckily I do lurk

The best I can get out of the xfx 7970 dd is 630mh @ 1050/900 intensity 8, 73c during day 68-70c at night. Had accidently ran the card to 120c before crashing.

Dont need heater at nights now with 7970 and 7870 hashing away

I am considering changing to arctic cooling to make it cooler

I have done cpu mining on windows 2008 r2 servers about two weeks ago and converted them to do LTC cpu mining generating 0.1 LTC per day.
Anyways first thing is first, do you have a video card?
By the sounds of it, your mining software is not detecting a compatible video card.

Second if you are CPU mining then you will need to use pooler's cpuminer that has been the fastest I personally tested, however with a dual xeon 5430, I was only get about 15-20MH/s mining BTC using 4 cores.
Switched from ufasoft to pooler's cpuminer and started mining Litecoins instead with that server and getting about 40-45KH/s on 5 cores.

there are miners
hell I have couple of mates in Perth mining
firstly does your mac have a video card preferably an ati?

While some of that statement is true, if you do deposit or withdraw more than a certain amount, the institution is legally bound to report it to AUSTRAC.

To my understanding about AUSTRAC, keep the transactions under $5k and you should be fine.

This is the case with bullion dealers but with banks it might be $10k, do note quote me on that

fair enough

What I'm trying to understand is people complaining about the worth of bitcoin going down. Why people didnt do the same thing when it was going up?

try cooling it down
i had my xfx ghost dd 7970 at 650mhs but the temp was like 90+ degress getting alot rejects
after almost a week of tweaking, now doing 655mhs but at 70 degress at the expense of 4 6cm fans blowing directly on the card and getting 1 rejects every 1000
mind you this is bitcoin

Great to see another company in action
It is possible to get those results when working with a fabless company but initial designs would cost quite a bit, and then there is prototyping which would explain the initial $, as with the other two asic miner vendors, their initial price were around $1500 mark and then recently have jumped.

I have also researched into getting some asics designed for bitcoin and hopefully start my own fabless from the proceeds, but the initial investment and time frame was too much of a risk, entering asics this late in the game is very time sensitive but very needed.

I have also done a preorder and got an email confirmation of batch 1 order #29

Good Luck on the adventure

it is what ever you are Proficient with

your not looking hard enough

there is one open source fpga board design out there

I am currently looking into it as well

start one

litecoin mining is abit different from bitcoin

clock/memory where memory should be higher

https://bitcointalk.org/index.php?topic=117221.0

try that

If you read to the right side of the column it also says 1100 clock speed and the card you mention on that link is clocked at 1250 with changed heatsink

I also own a 7870 Gigabyte OC 1100MHz from the factory and a 7970 xfx ghost dd

anyways if you cant get 12.8 to run theres something wrong

what operating system do you have?
