Topic: [ANN] Sfards:SF100, the first 28nm Dual-Mode Miner is accepting pre-order now - page 41. (Read 129801 times)

Sorry to hear this.  I am pulling for you  job markets tough.

I hope you can build a piece of gear worth buying from you.

@ op is this 1129 number sure?

I'm going to, but I've lost my job few days ago and right now I'm organizing my life to survive that 2-3 months of designing. Prototype realese will be painful

My idea is to design and published as open source two universal heatsinks. One air cooled and 2nd water cooled. This heatsinks will accept universal DC/DC converter and universal controller board. Only one variable is ASIC's board. Why open source heatsinks? Becuse it's heaviest in this whole mess and transport costs are huge. You can order heatsinks in your area, boards from me, and cost are considerably lower. In future you only order one PCB and download new firmware...

Sounds reasonable...  Especially, if the hash rate is similar to that of the SF100.  I like the sound of cheap and easy upgrade as well.  That's what attracts me to the Miner's Edge rigs out of Austin, Texas.  And the fact they are water cooled; except for the PSU.

Not for everyone. I think that with my design and 20$/SFARD_chip this miner could cost 849$ (fast calculations). With easy (== cheap) upgrade in future,only one PCB to replace with screwdriver....

Understandable...

Only if ASIC's manufacturers will want to sell their precious ASIC's @ reasonable costs. Not 10x manufacture costs...

sweeeeeet

Working on it....

No one has confirmed that.  So, I'm deleting some of my previous posts until I know for sure.  I don't want to jump the gun. 

Has anyone actually confirmed that the price raising temperatures here is correct? If so, does it apply to the 100 unit "bulk orders" or to single units? Also, does that include shipping?

Bitcoin single mining mode: Hashing power 1700 GHS, power consumption 770W.




Litecoin single mining mode: Hashing power 47 MHS, power consumption 180W.





BTC @ $243.577 = $4.191 per day with 1700 GH/s

LTC @ $02.86844 = $3.418 per day with 47 MH/s

Total Combined = $7.609 per day

Rig price @ $1,129.00

All of the following ROI's assume:

1) the difficulty remains the same
2) the price of bitcoin remains the same @ $243.577
3) the price of litecoin remains the same $02.86844
4) your pool is constantly at 100% luck for the day (BIG IF).

Also keep in mind the following ROI's may or may not include additional cost of shipping:

those nice bad guys. i might get one in case.  or a used alcheminer 256 Mh/s for $599 from alcheminer's website. only if you got enough cash for shippng, customs, etc. though.
sorry for being off topic. im curious on how Sfards will turn out with their mining performance.

Yes, the yawn is contagious.   yaaaawwwwwn

After reading that link I posted, I see nothing in it about next generation rigs by SPT online yet.  Sorry about that.  I can't remember where I saw that.  I may have read it wrong the first time.  I could have swore I saw some were online now and more is in the process of being made to go online.

So we should expect a "big yawn" from the Bitmain marketing guys? No pressure to announce/release an S6/S7 product?

This pricing puts this pretty much in line with Bitmain's pricing.  Fairly close anyway.  This is assuming it actually mines at the hash rate advertised.

A little less than 60 days at this present post.

I don't keep up, but isn't the next LTC "Halving" way sooner than 180 days?

Okay, thanks!  Just making sure.

I suppose a large farm with $0.04 per kWH or less in power costs may consider jumping on it.

However, bare in mind, the price does not include shipping.
