I quote air cooling stats because I have no rodent hindquarters to donate regarding immersion cooling. I want to play with these chips and I design for practical air cooling because that covers myself and all my target customers. I do not care at all what Bitfury builds for themselves or their millionaire buddies. That's my reason; can't speak for anyone else.
Indeed...and designing a power stage to deliver clean and effecient .3v power should be interesting haha, even at 5w were talking about near 20amps of current. The only way to achieve those efficiencies at that voltage level is with a chain design...otherwise your looking at less than 80% efficiency just at the buck at those voltages. |

Hey guys,
I am brand new to this forum-site, but am reading a lot because i want to know if it is still proffitable starting mining right now?
I do a lot of research of different miners but can't seem to find the proper gear to start.
What if i have a budget of around 5K USD. Can somebody tell me what is best to start with?
I saw the Zeus Volcano, but also read some articles of the KNC titans.
I now only look at scrypt mining because of some scrypt-coin calculations i made, i think this is more profitable then SHA-256 mining.
Right now i pay 0,24 cents for current.....(yes i know it is a lot)
But when i check out the mining-calculators on coinwarz.com some of the scrypt coins are still quite profitable....
What can you guys tell me, inform me, teach me?
Because i can't seem to contact zeusminer.com and at the site of KnC i can't seem to find the miners.....
Please let me know what you think (maybe i look at it wrongly and can someone steer me in the right direction)
Many thanks in advance.
You have a lot of research to do. KNC and Zeus are long gone, neither make scrypt hardware anymore. Zeus was first gen scrypt and those chips are no longer profitable. Your best bet for "new" hardware is Innosilicon, with their A2 stuff. Otherwise you can pick up used Titans which offer the best efficiency of whatever is out there currently. |

Did you get my last message and verified sig?
sent you a PM |

54 Mh/s @ 250 watts is unbeatable in the Scrypt market right now.
unbeatable ? Titen ? 400 MH @ 1400 watt ... not rally unbeatable ... Ive never seen a Titan run below 5w/MH...maybe 4.5 but thats pushing it. |

The batch is officially sold out! Thanks to all that put their trust in me and ordered in advanced of shipping. Things are still on track to get these assembled and start shipping end of Dec/first week of Jan so all the orders keep an eye on this thread and will keep you updated. Ill ask for final payment + shipping when I can ship your order within 24 hours. These will be shipped out in the order I received original requests (check the order sheet the list is in the right order). Ill post more detailed instructions closer to shipping date.
Congratz! Love to see projects like this do well. Hope its the first of many scrypt projects from you  . Big thing these day's to sell out. So really congratulations. I think it really shows the support the community is willing to provide to homegrown asic solutions, were tired of the announcements with the huge price, extreme shipping cost and no competitors to choose from. Just wish we had more chips to choose from and build stuff with! |

Thats a lot of cord length for 12v. Be interested to see the voltage drop from PSU to miner. Hope your running at least 16 gauge.

That heatsink looks larger than the compac heat sink, is this correct or am I misjudging it?
That heatsink is a prototype(24x24x50mm), I think its taller and less wide than the compaq's . The final production version will be 25x20x45mm, have 7 fins, and black anodized. |

Some updates for you guys and more pics! Finally got windows driver working, so all 3 native bfgminer drivers for Mac, Windows, and Linux are pretty much ready. Below is a screenshot of the window driver testing with the final production version of the PCB. As you can see I got the high end of the stick pretty stable, most of you Alcheminer owns can attest that .33% HW errors on this chip is pretty amazing  Im pretty happy where the final version is and hope you guys agree! I was hoping that I could also make it super stable past 1 MH but unfortunately I think I have reach the limit of this chip...so much you can push a 40nm chip...  Below are pics of the board iterations...as you can see I shaved nearly 10mm off the original board...this does amazing things to voltage drop and efficiency!  And here is my prototype lunar army ready to take over the moon. Last one is the final production design.  |

Final numbers are in for PCB color...here are the totals between both forums Green 5 Red 6 Blue 10 Black 12 Yellow 7 Total Votes 40 Close one between Blue and Black but black takes it! Should look pretty sick with all black heatsink+pcb. I do have to give props to peon miner for his suggestion though Im finishing up component and PCB orders today and tomorrow...so now waiting game begins for everything to come over the next two weeks. Should still be on schedule to ship end of Dec/first week of January. |

In the last photo are those custom power busses you have the ATX wires connected too?? Pretty badass.You have a photo without the rubber shroud?

Yeah, I got pretty tired of eBay customers back when it was my main source of income. I don't know how many times I got offers on things where people wanted 50% off the list price. A lot of times I was selling something like a grade-A 17" Dell monitor for $50 shipped and jerks would try to haggle me down to like $30 or less. After fees it wouldn't even cover material cost and shipping, let alone packing materials, parts and labor, or me being able to eat this week. So many idiots on there.
I did get a response from Bitmain overnight. I pretty much laid out to them why selling us chips would be good for their business (including that they're getting a cut of sales they don't have to work for, and sales in market sectors they aren't even in, and increased R1 sales when Gekko-capable firmware exists, and the good publicity they get from community support) and they said what we're doing sounds interesting and they'll consider selling in the future when they aren't focusing all their chips on S7 manufacture. To which I responded, if I could get 10 or 20 chips that'd keep me busy for a while with prototyping. For real though, 20 chips would buy me at least a month of prototyping before I came asking for anything more.
So hopefully that turns into something. Not terribly optimistic for anything anytime soon. We did get samples of BM1384 about three months after the S5 started moving, and the S7 has only been moving for about two months so by that timeframe I've got a bit of a wait yet. Course dev should be faster this time around since a lot of work will already be done. If we have another Compac it'll be a bit more complex than the last one so to integrate software voltage control, so it'll have a controller and firmware kinda like the pod. Which I should be working on the pod next week, as soon as I get the Compac batch finished up.
Why not just buy an S7 and remove a chip or two from a board for testing? At the very least you can have a prototype working if they every decide to open up sales. |

Anyone know if these little sticks will work with any current pi mining OS like minera?
It can be built under RPI so yes it can work with it. Right now easily under raspbian on RPI can run, and I have one running. Minera would not have the custom BFGMiner loaded on it for the moonlander though. I think it will take a custom buid. This was done for the compac, so it's something very possible. Just don't think anyone has done yet. Im the current maintainer for the scrypt drivers on bfgminer, once the stick ships the driver will be merged into the main bfgminer branch. So it will work "out of the box" with minera. Of course doing this yourself is easy enough...you just need to replace the bfgminer directory minera builds with the custom driver for it currently. |

I have expanded batch size to 400 units, and removed people who had not submitted deposits by now so there are now 130 units up for grabs. All the people still interested please follow the instructions at the first post and send the 2 LTC per stick you want to the public address and ill add you to the list, and send me a PM with the required info.
DONT SEND LTC FROM EXCHANGES DIRECTLY.
Im hoping to wrap things up this week with the final design from tester feedback, and make component orders by end of the week. With holidays coming up there might be a week delay on shipments depending on how fast I can get pcbs etc.

Don't know if Stefan still reads this thread, i sent you a pm a while ago regarding the purchase of a few sticks. I never got a reply.
Could you please check your messages and reply if possible.
thank you
PM sent... I have also expanded batch size so if people still interested id place deposit soon, there are 130 left and that will be it. |

Would be cool if you added my scrypt stick to the thread. And I don't want to sound biased but I've seen that USB stick and its crap...its based on the old Zeus chip and overheats easily. That thing hashes at 220kh max if you can get it to not burn up, my stick starts off at 400kh at under 2 watts and goes up to 1mh. https://bitcointalk.org/index.php?topic=1248914.20 |

I added a poll for the PCB color in the main thread in the Altcoin mining section. Head on over there and cast your votes!

Now to the fun stuff...you guys get to decide what color the PCB should be for the stick. I added a poll so place your votes! The heatsink will be black anodized.

Can we get a hashing video pleaseeeee? Here you go! I got a little behind with thanksgiving but here is the video I promised of the pre-production version of the stick hashing. Video does not show off the LEDs that great but the Red led lights up when instructions are sent to the ASIC, and the yellow LED blinks when it returns a nonce response. I also sent out a few beta/review sticks so should see a review or two soon from people other than me https://www.youtube.com/watch?v=TSz6pBTUGZY |
