You still thinking of doing that S1/3 upgrade kit?
@ Sidehack: and still have that heap of old s1's I sent ya long ago? Would be good for folks wanting a ready-to run solution.

If/when folks are interested I still have a fair number of s3's that can be had just for cost of shipping within USA only.

Where you located?  I may take you up on one of these....

FWIW I picked up an S3+ miner on Amazon for about $250. Even though the power/hash rate isn't that good ~.7watts/Ghs it runs well and very quiet relative to the newer miners.

Waiting for the upgrade boards too. :-)

That's a horrible price to pay for an S3. They used to sell for $70 or less on pretty much every site, and even now you can get a better deal for them on eBay. First search I looked for on eBay was a $180-190 S3 with shipping factored in. Not a great price but still lower than your $250.

It's still a quiet miner though, enjoy!

Yeah but if he bought it more than a month or so ago, bitcoins were trading for roughly twice the current value and all miner prices were stupid.

But yeah that's still a bad price. I wouldn't have bought an S5 for that.

On that note, miner prices have come back down to Earth recently overall though there are still some holdouts on ebay who think $3k is a reasonable asking price for something like an Avalon 741... I sure hope people out there are not falling for it much but who knows.

It's certainly not a bad time to upgrade for all of us who buy second-hand miners and have the $$$ to do so.

Sending a pm if you still have s3's for shipping costs.

Hi @sidehack just wondering how your dabble with 16n chips is progressing..

Keep up the cool work.

Hi,
I thought that this might be interesting.
Bitfury has released a BF8162B/BF8162B21 Datasheet and it is including a lot of technical information.

BF8162B/BF8162B21 Datasheet - 1 May 2018 Revision: 0.5
http://bitfury.com/content/downloads/16-nm-asic-datasheet-2018-04-002.pdf

They released this while updating their website, now that they have introduced their new brand look.

I'll definitely take a look at that. The last BF16 datasheet I have is dated sometime September 2016, and requests for updated info were pretty much ignored or forgotten.

But will we actually be able to *buy* any? Is there a "don't hold your breath" emoji?

Niko Punin (Head of Product Development) promised the chip supply for GekkoScience projects many many days ago,
hopefully he would still be able to do that and help us little guys.

I emailed him about a week ago with some questions about updated pricing and timelines, but have not heard back yet.

Which admittedly is no surprise. Historically I only got responses to about every third inquiry.


EDIT - that new datasheet looks to have a bit fancier graphics and some added efficiency curves (but with no axes for core voltage or operating frequency, so about half useless) but all the rest of the content is, far as I can tell, identical to the datasheet from 2016.

Sidehack,
I'm sure 16nm will soon be a better buy as 12nm becomes the next standard. Would be interested to know if it would be better to try 12nm.
Also as Bitmain creates other algo type miners would it be possible for you to create the same if you find a market for it. I enjoy my compacs as they help out my bigger miners if they go down and stabilizes the potential earnings.

Right now 16nm is the best I have access to, but that won't always be the case.

If you know me at all, you know I don't really care about other coins.

Oh hey guys, here's a bit of an update.

I have today sent off for prototype PCBs for what I hope to be the final version of a new 16nm stickminer. It's going to feature not just improved hashrate and efficiency, but a fully integrated control package that, once we finalize the firmware and driver support, will mean we have provision for temperature monitoring (of both PCB and ASIC die) and software voltage control. So no more tiny screwdrivers. We could have rolled a stick out two months ago if I'd been okay with tiny screwdrivers, but there was room for improvement so I designed the whole control package.
Following on the stick's heels will be a much-improved pod miner, building on knowledge gained from the (ultimately disappointing, from my standpoint) Terminus R808 project and integrating an expanded version of the stickminer's controls. Improved housing, improved cooling, power use monitoring, fan speed control, it's gonna be nice.

However.

In the last two months, bitcoin has taken some pretty massive dumps. That may be nice for long-term investors who are using this opportunity to buy, but it sucks for everyone who actually uses the currency as a currency - that is to say, as a means of exchange for goods and services. You know, guys like me. Not so friendly.

Anyway, the year's downturn in general has killed the resale market for my bread-and-butter 2Pac USB Stick Miner. So operations are consuming most of my cash savings, while my BTC savings are shriveling on the vine, and 2Pacs are stacking up on the shelf.

Which I see as heavily unfortunate, because I need the revenue from the final batch (or heck, even the parts cost of the final batch) to help sponsor the initial batches of the new better gear. I could have stopped production batch before last, but I knew the new stuff's production was still a ways out and I have employees who need paychecks, and "take care of your people" runs deep in my family.

Long story short - I need to get rid of my 2Pacs in order to afford to manufacture the new stuff that's better than 2Pacs. Do any of you guys want to toss in on some cut-rate 2Pacs to help fund batching of exciting new stuff?

Sidehack, first a big 'thank you' for all you do and have done for the community!

You've been great to work with, with the 2pacs I've purchased and run. Sadly, I don't really have the WAF (wife acceptance factor) to run more hubs and 2pacs right now.

I know this isn't what you asked, but I want to help fund if there's a way I can. If you'd consider such, I would happily preorder 5-10 of the new stick miners or even 2-5 of the pods.

Thanks in advance for your consideration!

Sidehack, how many 2Pacs you need to get rid of? @what price?

I might be able to help out with a few.

Thx

I really don't like pre-orders. I've relaxed the policy when necessary in the past but only for designs that had already been proven and I just needed to raise funds for an initial batch. This guy hasn't been proven in full yet - we've got 2 chips hashing, but not in a stick shape and not with controls. Definitely won't take money on pods since that scale of device hasn't even started testing yet.

It'll be tight but I should be able to at least get started on batching sticks. But the more 2Pacs I can sell for at least the cost of materials, the less I have to take a huge loss on selling BTC to do it.

No kidding, if someone asked for ONE THOUSAND 2PACS right now I could ship by Friday.

"12nm" is not a new process, it's a process improvement of "16nm" that is run on the same fab lines.
The rename is more about marketing than any significant change to the feature size.
It's also NOT going to free up any fab space or capacity on the current "16nm" lines.

Going to get even worse in the next generation - what Intel and Samsung (and IBM) are calling "10nm" and shipping TODAY is almost identical to the announced specs for what TSMC and GF are calling "7nm".

Then the generation after that - IF THERE IS ONE - may not be a silicon generation, given Intel comments about "10nm is the end of the road for pure silicon" and IBM using a mixed silicon/germanium wafer in their work on 7nm.




I'm no longer legendary just in my own mind!

now I'm trying to remember if that was the pixel size with the lithograph, or the size of the transistor they can make?..
makes no difference really with the transistor, they still produce heat when they switch states..
