Ahh, OK. I'm sorry, I thought you still accepted bulk orders.

We will stand and fight.
If I were to give you enough money to purchase 30 Icarus and 30 Lancelot miners today, what would be your estimated delivery date for both orders given everything you have today? (I do realize you still have a lot of development and it might be hard to estimate, but I figure it is still worth asking, in case I want to purchase Icarus for possible use or resale.) Thanks.

the answer is: we no longer accept icarus orders, and Lancelot is not have no delivery schedule now.

OP please don't kill me lol. I know that you're trying to sell your product and at 250mh/s per chip is not that bad. I said something about your board still being under production. I think you should up it up with 4 fpga's on to it. That's about 1gh/s at @ ~50 watts (I think lol).

 Cheesy

i think you will (or most of have this viewpoint) will change their mind after 1 month time form now. i still have some secrets.

500+ mh/s for $500 or so??? Even without any warranty I may be in for some  Grin

Good Luck !!!!!!!!

Can you explain why you're excited when BFL offers more MH/s/$?  I like having competition, but I'm not getting it?

Well,as you know BFL's shipping time is,hhmm,slow........& the lower wattage of Lancelot is a +.

But mostly,all but BFL's hash rates are pretty low=long ROI.Almost $600 for 300+ mh/s takes close to 15 months to recoup investment.

I hope to encourage higher hash rates by investing Cool

Also being unemployed,I can only come up with $500-$600 a pop  Embarrassed

Yea but you can save up and buy a BFL single. Lancelot should've been at least 4 Spartans. There are 3 competitors that offer good prices (Well 1 out of 3)

1: https://bitcointalksearch.org/topic/ztex-usb-fpga-modules-115x-and-115y-215-and-860-mhs-fpga-boards-49180    <----- $1,359.00
2: https://bitcointalksearch.org/topic/new-fpga-company-800mhs40w-boards-79114    <----- $1,069.99
3: https://bitcointalksearch.org/topic/cairnsmore1-quad-xc6slx150-board-78239    <----- $640

All these are Quads. They also got doubles.

PS. Kinda have to go, I'll post more info soon. Don't kill me just yet lol.

Yes,I have already ordered one single & have mined enough for half of another.By the time I get my single (in 3 weeks,maybe) I should have about $400 towards the next one Grin

I have 2 6950's & 2 6970's already paid for,mining towards singles.So the BFL ROI for me is about 4 months.

Quads are out of reach,too much cash to layout at once,until I have at least 6 BFL singles or a mix of FPGA's (Lancelot).This is the second best bang for the buck,IMO.

I just can't justify,this is my opinon again,anything with less than 1 mh/s per dollar.The ROI is way too long.

 Cheesy I respect the opinon's of others,even if they differ from mine...........& most do Cheesy

ngzhang,good luck.Thanks for getting your product "down to earth",pricewise & mh/s wise Wink

Small problem, BFLs use twice as much power per mhash and thus take much longer to pay themselves off, and you also have to start paying attention to cooling problems as well.

So I looked into the power issue, and say that the BFL does produce 832MH/s @ 80 watts. Hardware break even is 328 days. Lancelot if it pushes 500MH/s @ 25 watts. 1 year, 102 days. This is with the current price of BTC and a 0.103 kw/h cost of electricity. If the calculator is wrong, sue me - http://bitcoinx.com/profit/index.php

The calculator is wrong because although it uses historical conditions to predict the future, it doesn't predict a realistic window.

Now, if you believe the calculator is correct:

BFL's peak profit is at 47 months at $490.04.
Lancelot's peak profit is 57 months at $243.54.

So, yes, the BFL will provide the best deal. You make twice as much.

For Lancelot to be an equiv deal, it will need to cost about $250.

Now, in comparison, BTCFPGA ModMiner is 800 mhash @ 40 watts for $1070
ZTEX 1.15y is 850 mhash @ 38 watts for $1359

Modminer's peak profit is at 57 months at $119.61
1.15y's peak profit is at at 60 months at... negative $75.37. Thats right, the best you can do is lose $75.37.

Oh, and GPU mining? Lets say $400 for mobo, cpu, mem, psu, $550 for 7970, 250 watts usage at 1125mhz, 675 mhash each, four 7970s: 2700 mhash @ 1050 watts for $2600 or so. Peak profit is a loss of $917.51 at 24 months.

Edit:

BFL MiniRig is 25200 mhash @ 1250 watts for $15,295
BFL MiniRig's peak profit is at 57 months at $22222.48

Simple as that: They must have found a way to get chips that usually cost $2000-4000 each for less than $200.

Some people think they've found a source for used or unwanted chips, which is pretty sneaky^Wbusiness savvy.

i must say, icarus protocol is simple but efficient. by this protocol, one 20$ router can handle up to 70 icarus boards with a CPU usage under 10%. why all of you think we must improve this protocol?  Grin
certainly.... i must do some modify to support added functions.

No need to improve. It works. And works well.  If you keep the protocol the same, all miners (cgminer included) that support Icarus today can just implement the extra "fan set/read speed", "temp read" commands and support Lancelot with little change to their mining code.

Temperature and fan control would be a huge improvement over Icarus.

Any changes to the protocol? ACKs when jobs are done?  or still waiting up to 11 secs for response?

Does it work well with p2pool (with new workbase given on average every 10 seconds) ? GPU miners can choose the amount of work given to a GPU to control the latency which makes most of them able to work well on p2pool, is something equivalent already available or planned for the icarus protocol ?

certainly. this protocol can push new work to FPGAs at any time. and FPGA will handle it at that time.

Its better than Icarus but i dont understand why not offering quad FPGAs. Much cleaner setup, less power cables, and USB cables.


because we have a future plan, set up a rig by 8-16 Lancelot on a single mother board (which is less than 200USD cost), this cluster only have one 220V power plug and LAN ports (RJ45 and WIFI).
so until now, i still consider 2 FPGAs pre board is the best structure for balance the cost, size, yield, etc.
