Looks like a really nice miner

Coming out of nowhere and posting the same thing in 2 threads(but not on KnC thread too who is also selling some pre-orders) makes me think that you are paid by one of the competitor hardware manufacturer and the only one that comes to mind is KnC since they are the only one with equipment that is on pre-order. Also it seems that you posted this after the Special Easter Egg offer for KnC customers. It's more than obvious that you are paid by KnC.

If you have such care for the welfare of the world, why not join Médecins Sans Frontières. I'm sure with your moral high-ground and foresight, you will go a long way.
Perhaps you can tell me next week lotto numbers while you calculate how long it takes me to put you on ignore.

I'm sorry if it appears I'm trolling, but I am not.
This is a relatively expensive investment and any investment should be valued based on its estimated cash flows. Calling it "crystal ball gazing" doesn't change the fact that anyone that drops their BTC/Dollars on it is expecting to at least get their money back.

Again, I used very conservative estimates of difficulty increase and assumed BTC price stability. I am also excited about new technologies and appreciate the way that Spondoolies is doing their business, but why am I being flamed for examining the cost/benefit of the product?

all crystal ball gazing and trollish predictions of positive/negative return on investment, should have their own thread and not be added to any manufacturer thread. this thread is for the discussion of Spondoolies-Tech and their hardware, not for predictions of the future. People will do their own calculations, and make up their own minds.

If you feel the need to make assumptions on what this hardwear will/will not do, then please start your own thread and do not spread FUD here.

thank you and happy Easter.

Care to elaborate which "trollish assumptions" I have made? Stable bitcoin price? Lower than average difficulty increase?
If anything, I was very conservative with the numbers.

Please respond to the estimates I made rather than resorting to name calling.

Now that just seems like unnecessary tech-cruelty.

I vote for a more freerange keeping of your spondoolies units.

After all, the quality of your minted bitcoins will suffer when the fans cant turn freely in cool air, as they wish.

Raskul has a good approach there.

you are practising crystal ball reading? that's 2 threads you have spammed with your trollish assumptions.
you hungry?

Can someone look through my spreadsheet to verify my estimates on the SP30?

https://www.dropbox.com/s/xvhh105nmgfokdv/profit.xlsx

you got it wrong,it's 10m3 volume, even better
power is at 0.14€/kwh max and will soon cost 0.10-0.12€/kwh

datacenter are way too expensive. when i look for a space most of them refused to add equipment like that or only with fees which cost more per month than all my installation...
btw, any hosting solution annoys me...

RawDog, we never hinted or said that the SP30 is a done product. We've said from the get go that it's under development.
What we're committed to is the spec: 5.4 THs +- 10%, 2500 Watt, 2U rack mounted form factor.
The first SP30s will be shipped to customers in July. This is another commitment.
It's actual look may be a bit different from the SolidWorks rendering in the web site.

The below is not targeted towards RawDog:
Please don't start another cycle of commitment vs terms of sales.

For the SP30, we'll use two 1200 Watt PSUs. We're evaluating:

Emerson              P/N DS1200-3-002
http://www.artesyn.com/power/power-supplies/websheet/401/DS1200
 
 
Murata                 P/N D1U3CS-W-1200-12-HA4C
http://www.murata-ps.com/en/products/ac-dc-power-supplies/1u-front-end/d1u4-w-1200-12-ha1c-6.html

None of them has the noise issue in low power as the Emerson 1050 we're using in SP10

Is there anything else 'misleading' that we should know about?  The more things the manufacture 'misleads' me on, the more plans I have to discard and start over.  Would any of the other things you are misleading your customers on have the word 'August' in there? 

Well you are talking about 11,4 KW of cooling capacity, roughly 41000 BTU if i am not mistaken.
Yes, this will take some serious engineering... and maybe a datacenter solution would be more fitting.

I can see this working in a double garage (or even a single one) but in a 10m² space?
I hope your power is cheap so it will be worth the effort.

not if you live in an apartment at the 4th floor. So you know, the miniDC (i'm gonna call it like that now;D) will be close to my daughter's room.
Already have some experience with sound less engine. I don't think that this low 70db will be a problem.

Btw i'm not using low profile acoustic foam. I'm using professional foam. cost less than 130€ to cover the entire room including the door.



don't have space to run them flat.
and yeah, the foam modify slightly the sound because it breaks the wave, but you have to admit that if you're 3 meters away from the door you won't hear a fly fart.
Do you hear about the alpha sabine factor ? it's the value indicating whether the foam entirely absorb the sound (=1) or entirely reflect it (=0). varies up the frequency.





Hi zvi, thanks to Kobi
Do you have specification of the fans 40mm and 80mm ? I want to do the math myself

EDIT : Thanks at Dogie for high quality pics, I've got it for the 40mm: http://www.ystech.com.tw/db/upload/product/p-201111817053-2.pdf

   model            RPM      m3/h   dB
2    FD124028EB-P        16000    44    51.5
3    FD124028EB-P        13000    36.3    49.5
4    FD124028EB-P        11000    32.2      47
5    FD124028EB-P        9500      28.3   41

so now just need the parameters used by the firmware.
now, even the fan are working at their lowest level I would need to extract at least 170m3/h per SP10. Give then fact that this unit has 80-90% efficiency it would mean that I have to extract at least 150m3/h per SP10 and lets say 300m3/h for SP30. I need to extract 450m3/H * 3 batch = 1350 m3/h !!!!!
The room is only 10m3, it mean that i will need renew the air of the room more than twice a minute to keep the temp inside same as outside the room.
This is ridiculous....

For setting the record straight, the PSU noise becomes dominant only in quite mode (~1.35). In regular mode (~1.45) our fans create the dominant noise. As Guy said, SP30 will have bigger fans. Also, if Emerson don't fix the noise issue, SP30 will most probably have different PSU.

Hi. Here is a reply from Kobi, our VP operations:

There is no problem to install the SP vertically.
There is one issue he should pay attention too:
 The Air flow and the inlet air opening physical size of the "Extracteur Winflex VK 100 mm 250 m3/h" is sufficient to ~2 SP10 or a single SP30.
Installing more units in a closed room will cause the hot air to be captured inside and to increase it total temp.

Are they already set up?
I remember stumbling across them early this year and they were only taking preorders to reserve space, stating that they would be ready in Q2.

(sorry for the thread-hijacking)
Apparently they are already running 60+Th.

My guess is that the long-term hosting solution by spondoolies will offer a good SLA for any services specifically for your units,
in a professionally built Datacenter (maybe even with some "green" power) that can handle the cooling and power requirements well.

About hosting services, have anyone tried https://hashplex.com/?
They seem to offer really competitive prices (indeed 50% cheaper than SP) but that 1 year minimum makes no sense to me in a world like bitcoin where everything changes in just a month.

The render may be misleading. SP30 will have 80mm fans
