I'm currently looking at running just a single K16. Has anyone given any thought to using a wall wart with a Molex connector (e.g. http://amzn.com/B002TJNDU4) and running it through a molex-->pcie adapter? Are there any reasons why that wouldn't work? I would love not to have a large, exposed power supply if I don't have to.

Take a look at this little guy: http://www.newegg.com/Product/Product.aspx?Item=N82E16817129006

Fanless, and enough for a K16 plus a rPi, for only $5 more.

Very cool! Thanks for the link.

I'm poking around looking for case/housing options for these miners.  What are the anticipated final dimensions of one fully assembled unit, please?  If the unit is stored in a case, would the bottom standoffs still be necessary? (i.e., do they serve some purpose other than providing spacing between stacked units?)

I'm planning on mounting 4 units in a slim micro ATX case, using something like this:



You do need SOME sort of standoff to keep the PCB suspended in the case, and you will need the others to hold the fan up.

I believe the K16 is 10cm X 10cm but its height is variable(heatsink!).

Here's the Klondike discussion thread: https://bitcointalk.org/index.php?topic=190731
And here's the github: https://github.com/bkkcoins/klondike

If you're not stacking them then the standoffs will probably attach directly to the case. Think about the standoffs on a regular computer motherboard that attach it to its case; same idea. The bottom standoffs keep the uneven surface of the assembled PCB from just sitting there on the bottom of the case.

I'm thinking about just making a case out of plexi when the time comes. It'll be cheap and easy and it'll look neat.

There's lots of good ideas for assembling large amounts of these units into something workable (I just read a six page thread on how to set up a rackmount version of these ... scary how much firepower could fit in one rack!).  I'm thinking more along the lines of making a small, discrete box for a single unit, or maybe two.  I just want something to protect the miner from dust, bumps, random spills, something like that.  I don't think I'd want a full PC case for just one or two units, even a micro-ITX style one.

This is how I look at it: There will be room for expansion in a PC case. You may want something small now but what about 6 months from now? Why keep buying small cases when you can get a cheap computer case now and be done with it? The PC case has the added benefit of being pre-drilled for your power supply. Just a thought

Thanks for the info everyone.
Reason I asked about the PSU and size was I was trying to figure out to fit it in a Ikea Helmer.
This was where I saw a certain build. http://www.helmer-air.com/

I also apologize if I derailed the topic from the chip purchases to psu and other topics.

The issue is simply power at that density. Roughly every 30 K16s will consume around 1kW (32W * 30 = 960W). Since your average home can only handle several kilowatts (generally less than 6kW), that means that stuffing more than 100 K16s is neither needed or realistic. (Plus you have to start to worry about the DEA showing up) Datacenters & co-location services have the same problem, most are limited to 20A or 40A per rack. Anything more starts to get absurdly expensive. Very curious how steamboat plans to run his hosting service.

I've been rather stuck on these power supply limitations, would like to buy a large batch and scale-up but have no idea how to power a ton of K16s even though they would easily fit in the basement. I'm starting to wonder if maybe home self generation begins to make sense. Natural Gas fuel cell generators come in 5kW and 10kW sizes and are very efficient at generating electricity, they just cost a large amount and require installation, at that point though it's no longer a hobby...

Since your average home can only handle several kilowatts (generally less than 6kW),

I already have a miner consuming 1kW, my house has 2x100A ie. 22kW (@110V), this is a 100yo house, most modern North American houses have 2 x 200A coming into them ie. 44kW.  Australian houses generally have 80A ie. 19.2kW (@240V).

Not sure about Europe but both of the about are a lot more than 6kW.

Very curious how steamboat plans to run his hosting service.

There are plenty of small businesses that legitimately consume a *lot* of current (think electroplaters for instance), you just need to be in a location with an independent street feed.

[cp1]

I think 100A service is pretty standard in the US.  Most homes only use 20%.  The 100A is at 220V also.

First, sorry the OT thread, it is just so quiet waiting for chip arrival 

I already have a miner consuming 1kW, my house has 2x100A ie. 22kW (@110V), this is a 100yo house, most modern North American houses have 2 x 200A coming into them ie. 44kW.  Australian houses generally have 80A ie. 19.2kW (@240V).

Yes, homes can use a lot of electricity, but it does not take a lot before you are flagged for abnormal usage. Very quick search found this, I've seen a ton of similar examples:
http://legacy.utsandiego.com/news/northcounty/20040326-9999-news_7m26wrong.html

"In his sworn affidavit, Carlsbad Detective Mark Reyes states an unidentified, confidential source told a county Narcotics Task Force agent that someone might be growing pot in the house. Investigators subpoenaed utility records, which showed the Dagys used 1,584 kilowatts of electricity in February, and 1,616 kilowatts in January, the affidavit states. That's three to four times the amount used in neighboring homes during the same period, according to the affidavit."

I remember 1,500 kWh per month elsewhere as being a limit that gets interest or being different from neighbors. That is not a lot. 1,500kWh translates to roughly 2kW per hour consumption. So that 1kW miner plus your normal usage starts to get you close.

For comparisons, my home bases at 400-600 kWh per month, which is about 700W average consumption. If I all of a sudden I jump 500% to 3,700W average consumption (100 K16s + home use) what happens?

Being paranoid? Probably. But isn't the whole point of Bitcoin that you are overly paranoid regarding government backed money

Hell, in the summer, we use 4kw per day to cool this place down.

Immediately upon verification of the payment gateway, assembly will be made available for purchase. All parts for the first 5 batches are being sourced with parts to spare, and it is critical your assembly option is confirmed and payment sent promptly. This procedure is not ideal, and we apologize for the short notice.

Is there an ETA for getting the payment gateway setup? Also, how soon after that will payment for assembly/shipping be required?

I'm in one of the later batches, but plan to pay for assembly soon after the payment system opens. But I'll need some lead time to get the bitcoins into my account, so it would be great to have an estimate on when we should plan to pay.

As far as assembly, how will the orders be prioritized? Will it be by order date, or by assembly purchase payment date, or some other method?

Thanks again for all the work in setting up the group buys and assembly!

My guess is that you have plenty of time... weeks at least.

He's indicated that priority is based on first in first out order based on order date/time.

I didn't realize he had already spelled out the priority of assembly, but that order makes sense.

Still, from the OP it sounds like there is some sense of urgency in making payment for assembly, and I want to make sure I'm ready.

In the event a batch stalls, refunds will be issued to the addresses used to fund the purchase.

How much of batch 6 has sold, how much remains, and what is the deadline for filling that batch?

Yes, seems to of stalled.  Maybe to move the thread to Group Buys.

Why move it? It seems to me it's still an active thread, with presumably more information to come regarding the hardware assembly for the completed batches. I personally think it still has a place in the Custom Hardware thread.

Also, batch 6 has already been purchased, correct?

[brishtiteveja]

What's the update of batch 6? still 3333 remaining?
