      Well 15 total :) over 2 machines. I have purposely not calculated the odds because i don’t wanna know! If my bfl jally ever arrives that will also be on the solo project.
      Here is my bat line

      cgminer-nogpu.exe --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S COM2 -S COM3 -S COM4 -S COM5 -S COM6 -S COM7 -S COM8 -S COM9 -o 127.0.0.1:8332 -u T -p test

      i reuse passwords everywhere so feel free to hack my gibson.

            i bought mine on ebay.
            from this guy:
            [url=http://www.ebay.com/itm/10-PACK-ASICMINER-BLOCK-ERUPTER-USB-336-MH-x10-3-3-GH-s-ASIC-MINER-RED-COLOR-/151154368646?pt=LH_DefaultDomain_2&hash=item233180a086]http://www.ebay.com/itm/10-PACK-ASICMINER-BLOCK-ERUPTER-USB-336-MH-x10-3-3-GH-s-ASIC-MINER-RED-COLOR-/151154368646?pt=LH_DefaultDomain_2&hash=item233180a086[/url]

            the shipping cost is high for the first (75$), however each above the first one is basiclly free=)
            From US to norway it took 2 days from order til i had em in hand!

            i also bought theese:
            [url=http://www.ebay.com/itm/90W-power-20-port-USB2-0-HUB-USB-HUB-Industrial-grade-HUB-for-Bitcoin-mining-/151155337245?pt=US_USB_Cables_Hubs_Adapters&hash=item23318f681d]http://www.ebay.com/itm/90W-power-20-port-USB2-0-HUB-USB-HUB-Industrial-grade-HUB-for-Bitcoin-mining-/151155337245?pt=US_USB_Cables_Hubs_Adapters&hash=item23318f681d[/url]

            Works like a charm!

            However, will i ever reach ROI? most likely not… i can run em until the diff reaches 2000mill, then they consume more power than value they produce…

              I did at czech clone of e-bay [url=http://www.aukro.cz]www.aukro.cz[/url]
              But whole internet is swarming with erupters. Try Amazon, e-bay…

                Do you see what I see?
                (6 erupters on each side 8))

                This one is smaller, but waterflow should be better:

                  Would you mind to post picture of your erupter farm?

                    Do you have to use extra cooling with that USB rig?

                      [color=blue][b]arctic cold eruption[/b][/color]

                      Simple tutorial to overclock erupters, just change oscilator, 1resistor and add big heatsink:
                      [url=http://www.designer2k2.at/mods/elektronik/85-block-erupter-overclocking.html]http://www.designer2k2.at/mods/elektronik/85-block-erupter-overclocking.html[/url]

                      Cant wait for my watercooling block I mentioned earlier in this post.
                      [url=http://www.ebay.com/itm/122x41x12MM-Aluminum-Water-Cooling-cooler-Block-For-PC-CPU-GPU-Heatsink-/281148521160?pt=US_CPU_Fans_Heatsinks&hash=item4175c1fac8]http://www.ebay.com/itm/122x41x12MM-Aluminum-Water-Cooling-cooler-Block-For-PC-CPU-GPU-Heatsink-/281148521160?pt=US_CPU_Fans_Heatsinks&hash=item4175c1fac8[/url]

                      Also I ordered “cheap bay hub” which I want to re-wire and boost with 5V 6A led strip power supply, my inspiration is here:
                      [url=https://bitcointalk.org/index.php?topic=253749.msg2909052#msg2909052]https://bitcointalk.org/index.php?topic=253749.msg2909052#msg2909052[/url]

                      And of course cheapest chinese red Raspberry Pi I can get from e-bay at ±31USD.
                      (there is lot of rumors that they are shitty, on the other side lot of users have no problems with them…so I guess there is only one way to find out)

                      So my idea is:
                      water cooling (cheap)
                      overclocked erupters
                      modify cheap USB hubs
                      all made around red rPI

                      Right now, everything is ordered from ebay, waiting for delivery, while erupters are occupying all my PC’s USB ports :)
                      For testing purposes I will just use my small old aquarium and pump to see how it goes.

                      Also looking for small heatsinks to other side of erupters, there is a lot of 100pcs. 8.8x8.8x5mm at bay:
                      [url=http://www.ebay.com/itm/100Pcs-Lot-8-8-8-8-5mm-Chipset-Aluminum-Heatsink-Sony-T4000-Thermal-Tape-/121199492739?pt=US_CPU_Fans_Heatsinks&hash=item1c380d7e83]http://www.ebay.com/itm/100Pcs-Lot-8-8-8-8-5mm-Chipset-Aluminum-Heatsink-Sony-T4000-Thermal-Tape-/121199492739?pt=US_CPU_Fans_Heatsinks&hash=item1c380d7e83[/url]
                      however those seems to be to big an 100pcs. is too much…so I am looking for smaller base, but taller heatsinks atm…

                      Also I have no idea how to use hot water right now ;D

                        I wish they cost the same as erupters :) (they will soon…)

                          [/quote]What temperature do you think it would move them to? Boiling?

                          Could be constantly churning out tea or maybe drip brew coffee.

                          The coffee shop owner I crash with on weekdays would be elated by this since he wants to futz around with crypto but wanted a value add to it.

                            I have no idea, this is my first water-cooling system I am building.
                            (Dimessions and price of both erupters and heatsink was just so tempting :) )

                            They are pretty hot when I touch them with finger, but still only 2.5W.
                            After overclocking it should be [b]3.5W x 8 = 28W[/b], not much…seems only small volume of water will be needed.

                            I will definitely measure the temperatures after I recieve the goods and assemble it together ;)

                              This is really cool. I did a post a while ago asking if someone could build a crypto miner that doubled up as a space heater, so that people could heat their homes over winter while making coins and processing payments on the network.

                                I see this project viable for some smaller-scale aplication due to low power:
                                Maybe can protect pipes or tank with liquid from freezing in winter or something like this…(i.e. in garage).
                                Maybe I can keep water for my 2 cats drinkable during winter.
                                There was good idea of keeping warm coffe mentioned above.
                                Far from warming house (unless you have some high-tech passive beast house), but might be usefull :)

                                  Someone requested an image from my setup (pm).

                                  Didnt have picture but uploaded a video of it instead…
                                  [url=http://www.youtube.com/watch?v=YWwNGqoAsjE#ws]blablaftcblabla[/url]

                                  I have those arctic 92mm usb fan (one on each 20 port hub). BUT i also have a dedicated windmachine (that fucker can push air! when i mount it on a window so it pushes hot air out in that room. the door in the back will close itself due to vacum!). Overkill but i have alot less hw errors with this cooling ;D

                                      Damm,

                                      Another idea was born in my head:

                                      [s]Heat[/s] Keep warm your cup of tea while mining BTC!

                                      [url=http://www.ebay.com/itm/USB-Tea-Coffee-Cup-Mug-Warmer-Heater-Pad-with-4-Port-USB-Hub-PC-Laptop-Chocolate-/150729201691?pt=UK_Computing_USB_Cables&hash=item231829181b]http://www.ebay.com/itm/USB-Tea-Coffee-Cup-Mug-Warmer-Heater-Pad-with-4-Port-USB-Hub-PC-Laptop-Chocolate-/150729201691?pt=UK_Computing_USB_Cables&hash=item231829181b[/url]

                                      Two erupters under circle metal plate can do the job!!

                                        My errupters (another bunch) just arrived, but I still have to wait for my USB hub.
                                        It is breaking my heart.
                                        Perhaps I will make a surgery of Panda ;)

                                            My errupters (another bunch) just arrived, but I still have to wait for my USB hub.
                                            It is breaking my heart.
                                            Perhaps I will make a surgery of Panda ;)
