[ANN] Sfards:SF100, the first 28nm Dual-Mode Miner is accepting pre-order now

Where did youy guys get it? I need one too.

I'm wondering the same thing.  I would like for decent price.   

You could get it now for 2k likely from some resellers.  But I don't want to go through reseller and kill ROI.

You can't buy an SF100. Sold out.

Well, not exactly true. I see some for sale on Aliexpress for $10k, lol.

Your welcome. I am also a hardware guy as you can see by the rbox sitting on top of the SFARDS

so far its very stable been running a week straight before i powered down to plug the kill a watt in the full load picture was after it had been running a good hour or 2 i watched it go to 1000 then creep up 1 watt as a time as i guess it got hotter.

Unfortunately you cant get anymore as far as i know which was why i jumped on the opportunity to get one early

Tomorrow my S5+ comes in

That web interface and the way it works is similar to the one that was available and used mostly by people in China when the original gridseeds came out. It functioned with a specific controller that was available as an option with the 5-chip gridseeds when they first came out. I still have two of them around here somewhere. I only used it for just a bit to check out before rolling my own version of cgminer with gridseed support.

It wasn't until the 5-chip gridseeds started to become available outside of China that people started building alternate mining software. Until then everyone used it. It used to drop miners all the time so custom methods were developed to power cycle automatically. The old controller is a device similar to a Pi...forget exactly what it was but the generic version (without their custom firmware) is available that does something I forget. (might have been a WiFi extender.....but again, I forget)

You're lucky...the original web interface was (originally) only in Chinese. At least this newer updated version is in English.  

Either way...I imagine most people here will soon ditch it in favor of something more common such as cgminer once support is built. It seems this time around they built this controller into the device? Hope it is something generic like a Pi that we can provide our own firmware for....otherwise an alternative controller will need to be devised.  

Although the concept of a central cloud managed web interface to your miners is kinda neat...it even allowed updating of the device firmware from their site... I imagine it would make it easier to manage 100's or 1000's of miners... I personally was just more comfortable with cgminer at the time as it was familiar to me. I haven't checked out this new version so they may have made a lot of improvements....such as it being in English now

...also in theory I would think someone with back-end access to this cloud managed web interface could direct hash anywhere they desired...even siphon off tiny amounts from everyone so no one notices....we're such an untrusting lot aren't we

I hope that BitMain's chip announcement and the possible short term release of the S7 will put some price pressure on SFards.

Pretty soon they will have to share the stage with S7. And of course the LTC reward is going to be cut in half. After those events I don't think that the SF100 is going to be nearly as interesting as it was.

Well some of the last scrypt gear dropped and dropped crazy amounts in price.   I don't think we will see that level this time.

But it would not surprise me if we see a drop in price with announcement.  They are unique as 1/2 is scrypt so the can justify a partial premium.

You are in the wrong spot go over to hardware sales.  This is considered hijacking thread for sales.

A2 has nothing to do with SF100.   If it was a SF100 you were selling then it would be kinda ok to post here.

The good part is it still should kick the older generation of asics offline and make room for more efficient miners, if this will be enough to accommodate the half amount of coins I
have no clue.

 Only if they drop the price enough that they can manage to sell a significant number of them.
 As of right now, the only folks that would buy them are people that don't care about RoI or don't know to figure difficulty increase into an ROI calculation.

[mindtrip]

you forgot to mention hardware junkies who always want the latest gear to test and do write ups on for the benefit of other forum members

 Nope.

 That's a subclass of "people that don't care about RoI'.

Will wait for the price to adjust to market. One way or the other prices will be coming down

Yep...you have to remember gridseed blades (SFARDS is rebranded Gridseed) sold them for like 3k initially, prices then plummeted to under 1k each  few months later.

The less people pay for these overpriced miners the faster the price will drop.

[p3yot33at3r]

I don't think they have any intention of dropping the price, or even selling them to customers. They'll just mine with them themselves & rent out hash to victims customers on their cloud mining site.

Even if they did drop the price enough to make them almost worth while buying, I still wouldn't buy one, due to their complete lack of communication in general. Sfards last post here was on July 27th - almost a month ago. Not only does that not sound like a company that's keen to promote a product to potential customers at all, but it makes me very worried about the standard of customer support I'd get if I had a problem. I already know from experience that they ignore emails, but add to that their lack of information/communication here or anywhere else & the signs are not good at all. Terrible in fact.

Screw buying these units. At ~$215 USD right now, you are WAY better off just buying BTC on an exchange instead if you are profit-minded.

I agree today is a great time to buy

[jstefanop]

Yea with 200 BTC and $3 LTC (equivalent of $1.5 after that halving tomorrow, which is the same it was pre pump) things are not looking too good for any sort of mining in general.

It is sad they missed the halving.  It is crazy thinking about this to me.  I would have been pumping out these machines as much as I could long before that halfing.

Now the question comes did they mine them their self, and selling 5 to a few resellers.  I will be very curious to say the least if they have lot's of stock after the halving.   If they suddenly come with new batch in a day or two we will know they were mining their self.

New manufacturers tend to cater to the community and talk a good game until they have a fully operational magic money machine in their hand.  Then their priorities suddenly change. 
Bitmain is the only company that has stuck around for the little guy.  Even that relationship is tenuous though.
