HashFast launches sales of the Baby Jet

[Visesrion]

Chips are still on schedule.   No delays so far.   Very close now!

Are we there yet?  No, but it won't be much longer.

Any news about hosting ? When you plan to receive the chips exactly ?

Please let us know if you are going to offer hosting service or not, because I got at least 2 hosting offers pending and I would like to give them an answer

We plan to receive the chips during the week of October 20th.  Exact date depends on variable physical processes at TSMC.

I haven't heard any news about hosting, but we are planning on offering it and I'll let everyone know as soon as I get an update.

Fig. 1 depicts the difficulty at the time of purchase vs difficulty at the time same miners go online.  Please tell me how the Day 0 profitability could have been calculated.

It can't but you know difficulty isn't going down so when the network is 80 PH/s BEFORE you place your order and even conservatively it will be 100 PH best case scenario and 125+ PH worst case scenario before you receive your hardware that is going to weigh in on the minds of buyers.

In other words, expect delays. 2 more weeks(tm)? Say it ain't so HF...

The chips are pinned all they have to do is plug them into motherboards already installed in cases and ship them out.

So, just like KnC?

The speed was 200 TH when the KNC miners, just coming online now, were purchased.  Now it's not 400, or even 4,000, it's 2,418,00.  Two million, four hundred and eighteen thousand.  I'm not sure a worst case scenarios within 2x of the starting rate represent anything but wishful thinking.  For KNC buyers, it turned out to be over 1,000x.

When you buy a miner 3 months in advance of putting it online, it's virtually impossible to know if it will be mining at a loss.  Though if history of ASIC mining is any indication, you will lose money.

Finally, the shovel-dealer analogy is a bit flawed:  If the gullible gold diggers had to wait for 3 months to a year before getting the shovels they've paid for, the analogy would be apt.  Though those shovel dealers would have been lynched, their womenfolk raped & their stores torched if one of them dared to make such an offer.

Nowhere, because it is false.
The chips are not socketed.  They [will be] BGA, each mounted on its own board (similar to KNC devices, though each board will contain a USB interface).

They are not.  Given the relatively short lifecycle of miners and the lack of need for upgrade chips designing a socketed package is just additional for no benefit.

Then again with automated fabrication it is more than possible for an assembly house to place/solder/test thousands of boards a day.

HashFast tells me they're going to e-mail later tonight about the support position for the forum here, if I get employed I'll forward you guys details as soon as I know them.

Misleading blog post title! However, Seasonic is awesome.

Totally, I was like upping the power consumption or hashing power then blam total let down...

[Wesly]

Redundant power supplies?  That would require 2 PCI-E power inputs per hashing module?  Or is that just for power load balancing?  Kind of over kill unless the new 4U chassis can accommodate more than 3 Hashing units?  Am I dreaming or does it looks like there is room for at least another hashing module on top of the lonely one to the right? 

[DeathAndTaxes]

Yeah it does seem confusing.   I can't see any reason for the second power supply.

One new thing is notice the usb port above the left power supply.  It looks like it connects to one of the boards.  So single usb port to board #1 and the boards 2 & 3 daisy chained off it.

As for a 4th module you could certainly mount a board but where are you going to put the watercooling radiator?



HF is the same water cooling radiator used for BabyJet with obviously only 1 used (2 if upgrade module is installed)?

i was looking at the specs of the 2 psu's last Monday and the combined wattage greatly exceeded that needed for 3 modules which i calculated somewhere around 1400W.  while briefly cruising around the Seasonic website i noted that i didn't see any single platinum 80 plus psu above this, am i wrong?

Dual power supply sounds familiar. Now where did I see that? Oh, yeah...

[bobsag3]

I like the idea of Dual PSU, especially for expansion and failover

[tom99]

 What kind payment Hashfast take or Bitpay only?

Thank you.

I would certainly hope the Sierra doesn't require 1400W DC.  That would be ~1500W AC and would make the efficiency worse than 1.2 J/GH.  Given that 55nm Bitfury does less than 0.9 J/GH at the wall and KNC does less than 1.1 J/GH I would be hoping for something more.

The stated efficiency of BabyJet is 350W at the wall or 0.88 J/GH.  Assume a 90% efficienct PSU that would mean 350W AC is 315W DC.  Three times that is ~950W DC.   Seems that either a single 1000W Platinum or 1250W Gold PSU should be fine.

For the record, at the high end SeaSonic only has 860W & 1000W PSU Platinum models and 860W, 1000W, and 1250W Gold models.

One edit:
one thing I hadn't considered is that HF may be saving cost by using a single model PSU across products.   Say the BabyJet comes with 660W PSU.  Rather than stock a different model the Sierra comes with 2x 660W PSUs.  Note the above is just my theorizing.
