nice 

checking it out 

I am glad you like the look of it.

Liquidated 2 * CM1 FPGAs in Nov 12 in preperation for the generation change with ASIC and elec costs in Australia are just rediculous (25ckWh). With the halving and associated rig running costs resulting in a profit of ~$0.37cents per day, I decided the risk was to high hence the liquidation.

CPU + 2 * FPGA + wireless modem + monitor + NAS + cooling fans + power supply efficencies + 2*GPU [6770s @ idle not mining] + MB + HD= 60W+80W+40W+20W+40W+50W+10W+160W+20W+20W= 500Wh = .5*0.25chr*24 = $3 per day just to mine about 0.45BTC = Revenue - Cost = (0.45 * 10 [when BTC=~$10]) - 3 = 1.50 profit per day if running 100% but factoring 75% up rate I experienced = ((0.45 * 10)*.75)-3 =3.375 - 3 = $0.37 profit per day

Now I mine LTC for speculation. This is only done between boot up and when I get back to turn the mining off and start work.

When / If ASICs come out, then I may grab a miner or 2.

Untill this occurs, I will keep aquiring components to finish my hybrid solar / wind stand alone power system whcih will allow me to mine with confidence.

My testing rig runs 2 * 6770 for BTC & LTC mining in Australia.

The cards have been flogged for nealry 18 months now with card temps in the mid 80s celsius for a smooth 205MHs / 200KHs (BTC/LTC).

I have used cross-fire but then the slave cards only run at ~90% however, if crossfire is removed, they runn ~99%

I found cgminer was essential to smooth running.

Overall, they are very sturdy cards for Australian conditions.

I have now published my first short story, "Cyber Nightmares: For the sake of 9 million". I am making it free to download from my publisher via https://www.smashwords.com/books/view/255276

My drive is to write another four by Christmas to
offer an anthology of short stories tentatively titled "Cyber Nightmares: A series of short hacks".

Please let me know what you think of it, both the good and the bad, so I may grow as an author.

not heard of CM1's...you must have been smoking some heavy shit the past 6 months. Check the mining FPGA pages in this forum for info or http://enterpoint.co.uk/products/spartan-6-development-boards/cairnsmore-1/

happy to be of public service 

point taken....I apologise

yeah it is solved. I had installed "BOINC" for SETI, Search for Extra-Terrristal Intelligence, a few weeks ago then the disconnects started (hindsight is a wonderful thing) - just trying to use an idle CPU to further humanity. So a few days ago I uninstalled BOINC and it has remained stable since then.

I also upgraded to cgminer 2.9.0 --- not sure if this improved stability but I think BOINC was overloading my CPU as it was up flat out and then starving the FPGAs of data (my impressions).

If ppl are looking for FPGAs, I have 2 Cairnsmore for sale. They crunch 880MHs @ 80W. [WTS] add in the market place. I am moving over to LTC/gaming rigs were FPGA is not useful.

Due to spiralling utilities costs in Australia (elec = AU$0.27kW/h), I am looking to liquidate my two FPGA miners. I have qty 2, serial number 600 series, Cairnsmore 1 FPGA miners. Both have makomk's 220MHs bitstreams installed so they mine at 880MHs per board whilst consuming 80W/h. As a pair they mine at 1.6GHs whilst consuming 0.16kW/h which generates ~0.5BTC a day or 15BTC per month.

I am looking to change over my mining operations to LTC and as such the FPGAs are excess infrastructure. The funds from their sale will be put towards solar / wind power to run my LTC / gaming rig.

I am asking 20BTC + postage each. With ~4 weeks to go onto halving day, these babies should generate their new owner about 15BTC before reducing to ~7.5BTC. If you in a cheap elec zone or already have solar, then break even should be within 4~6 weeks of purchase.

Pls pm me for offers / discussions.

Cranky

what about Geothermal...if you have amountain range then it produces heaps of geothermal energy.

Australia is just starting the place geothermal plants along the Great Dividing Range, a mountain range that runs 85% up the full length of the east coast

I have a 1.5kW grid connected solar system at home. When I generate more thazn I can use I sell it to the grid @ AU$0.66kWh and when I draw more than I generate I buy it back at AU$0.25kWh. The system cost me ~AU$3k to have installed and will take about 4 years to break even.

I am currently building an 800Wp wind turbine which I will grid connect as well.

Renewable can be done but it is only cost effective were elec is very expensive. i.e. Australia is ~AU$0.25kWh were USA is ~AU$0.05kWh

thnx...sounds like a good excuse to acquire a DR Who Tardis 4 port powered hub....
