Topic: DRILLBIT SYSTEM Miners - Avalon range available - Now $104.99! - page 83. (Read 273811 times)

Has a difficulty drop ever happened? I'd figure unless they decide to make more bitcoins available that it would be the only way to make a difficulty change.

Can we maybe expect to see a price decrease in BTC since the BTC/USD ratio is on the rise?

Let me help you with the typing,

The last 3 on ebay in the last 2 days (in hand) sold for: (There were more auctions with high buy it now prices that didn't sell.)
$8500
$9995
$8399
($8965 average)

So, 500 Ghash/s works out to an average of $17.93 per Ghash.
I got 4 boards or 1 miniplane. The latter should get me around 80Ghash/s at $1300 w/ shipping. (Not including taxes).
That is $16.25 per Ghash/s. Now it is going to come weeks later but for a smaller unit to compete in price with a larger one is pretty nice.

The point though, is judging by how much miners sell for on Ebay, if you chose, you could probably get back more than you paid. (at least for the next 2-3 weeks.)

Still, for us small guys, a hobby that might pay for itself (and judging by BTC's future, will return a profit, probably a large one. Not as much as buying BTC's now, but still, not bad...)
And to have helped out the Network and taken part in the greatest social experiment of all time (and one that might change the world), I'd say the value is...

PRICELESS

What does it say on ebay a in hand one or a preorder for half november ?
If its a delivered one he payed $7000 without taxes, postage and customs
My saturn which arrived today costed me almost $5000 and thats just the miner, $ 120 postage and taxes

Mine until unprofitable then resell for an ebay premium?

I'll hold onto mine in case there's a difficulty crash, but it's always an option that you can work into your roi.

I was looking on ebay. It is amazing what Miners are selling for. For example, look at what you can buy a November delivery on a 500+ GHash/s Jupiter. ($5000 through KNC).
Now look on Ebay, I see them going for 7k. I really think some people can't or don't want to buy BTC and are willing to pay a premium.
Also, we were all taking a chance to profit on these, but I want to take part in Bitcoin. If miners stay unprofitable then I will take part in other ways, but
I am really looking forward to doing this regardless. Still a huge hobby for us that gives back some money. Indoor metal detecting anyone?

Well these might be the best deal going for hardware delivered in November, at least under $1000. However, mining dashboard shows I'll never reach ROI on these, even with a conservative 60% monthly growth in the difficulty. Looks like 1.7btc is the break-even number for pricing on these... (?)

SHHHH TOP SECRET

LOL - barn is mining with something at about 6Gh/s on Bitminter

12volts would be better in every situation due to the current design of PS's (heavy on the 12v side, light and running another converter on the 5v side). So yes, 1 mid sized PS could power hundreds of watts with no problem. Check the thread I linked to above. That is where the PS discussion is.

IAS

Any word on the chips and how the board firmware is going?

Wouldn't that be better for mini-planes connected with the double scrolls as well?

It depends if we go with 5V or 12V power. If we go with the former you might need 1 PS for each miniplane. If we go with the latter, you could power 4 miniplanes with 1 mid sized PS.
(5V requires more amps to power less basically, 12V can power much more with half the amps.)
It was brought up here, hopefully we go with the 12V. http://drillbitsystem.com/forum/index.php?topic=2.45

I'm wondering the same thing. Here is my post from a few weeks back.


Hopefully our chips are there or arriving. I think Barntech is finishing the boards up anyway, so he couldn't do much with the chips but would be nice to know if Megabigpower delivered on time.

Each board and plane etc has a ATX plug. I just need 1 PS or one for each?

You can hook them up any many different ways, there is no standard. eg. 1 board, 4 boards, 8 boards, those 3 configurations will typically have different case requirements, and then of course you need to add a power supply, some people may use ATX supplies, some may not, that's what DIY is all about. I am not going to bother with a case until I have a board in my hand, probably make a simple frame out of 12mm x 12mm pine, it will take me half an hour to organize and cost virtually nothing.

Is there a picture of a full set of these things all hooked up? Im interested just would like to get a visual of what its going to need for some sort of case to be made

thanks

Well to be honest i do like these simple cables and that connector they are more sturdy then all the other types i have besides the plain FAT usb 2 / 3 connectors

And gladly widely available the smaller types are fragile and do damage more easily

UGH . I cry every time I see those cables. I've got a small handfull of them from old gps's. It would have been more funny to have a usb3 micro plug on the boards though.

As far as i can see will both my old psu's available for mining are more then enough power able to feed anything either way

OCZ  GXS700 is a 700watts 3.3v (36A) 5 v (30A) max load 155 watts (combined 5+3.3) and  12 volt 4 x (18A) combined max 680 watts
Antec TPQ 1200 is a 1200 watts 3.3 v ( 25A) 5v (30A) max load 170watts (combined  5+3.3) and 12 volt 6 x (38A) combined max 1200 watts  
LoL and if thats not enough i got 3 more if needed

Anyway fopr easy of typing i call the 4 board drillbit mini planed system DB4 in my post

It is kinda important to know what it is going to use 5 volts or 12 volts ? and how much power it will need. I do know alot about servers and networking but not in electronics

The reason i ask is obvious i was planning on feeding the still not arrived saturn miner which is supposed to use around 450 watts with the TPQ 1200 however that is a pretty low load for this still very good psu so that would leave enough power to feed the DB4 if i am correct.

However it depends on what voltage the DB4 board going to use and how many watts it will need
What raised the question for me if "lets asume the DB4  use 5 volt 125 watts" will that mean that it still is able to deliver 1075 watts on the 12 volts rails or does it lower that significant?
If the DB4 is going to be feeded by 12 volts then how much power it will need ?

Ofcourse we need not to forget that alot of fans are going to be used as well, in my experience the fans kinda use often more then you think. I tested a the fan from a jala on my power meter and was shocked to see it needed 10 watts, i have not checked if all similar high cfm fans use similar power.
But it simply means that 40 watts minimal will be used for the fans in the saturn and probably some extra for ther beaglebone.

On the downside the antec does not have a power switch at all, i have contacted antec about this issue and still not received an answer
Do any of you here know enough about these psu's to tell me if there is a way to switch it on/off by adding a simple switch on the connector.
I have seen a person selling one with a fairly simple 2 pins switch, so my question is which switch will do 12volts 1 amp or does it need high amp ?
Can it be placed like the paperclip method or does it need another pin setting ?
Some people are telling fairly opposite stories about what happens when you simply pull the plug from the 220volt to turn that psu off
Will it damage the parts of the devices or does it damage the psu ?
There are a lot of discussions being made about this, but since i see answers saying one and other saying the absolute opposite i like to know from someone really knowing what he is saying in that matter.
