It looks an awful lot like it's fallen through.

Very sorry to hear,but I expected that.....Bitmain will be the last to sell miners for "home" use Cry

But with the diff rising & rising who can afford to mine at home with ASICs.....only folks like philipma1957 Cool

all my s-9's are in the solar array which is a homesite ,but with an 1 and ¾ acres of solar panels in a horse paddock does not quite count as at home mining.
Grin

but the eth mining at home turns profit at the moment. Wink

Yeah my eth "farm" is doing well too,only 4 cards but 3 are paid off after 3 months

Yes you are right , but:
5 V 1.2 A it is what - 6 W
with 6 W with theoretical specs current 16 nm generation of Bitfury you will get roughly 50-60 Ghs tops and the chip will be hot as hell, so the device will need good coiling - heat sink alone will have trouble to handle the heat or it have to be oversize .
This is my reason

My watercooling project for the gekkos may well have a purpose if I can ever justify the cost of doing it Undecided

Hmm. Random thought:
A lava lamp usually uses a 75w bulb so how about gluing 5 Compacs to the bottom of one on the outside of the glass in where the bulb usually sits.. Do they have blinking lights to add to the fun?
The temp of them should not get above comfortable warm...

I've pulled close to 15W out of USB for jacked-up Compacs before, moderate airflow on the stock heatsink. That's more heat into the ASIC than the S5 ran when overclocked.

Some of the new chips aren't 10W-scale chips like the BM1384 though, probably more like 5-7W I would guess. A stick might have two chips on it if that's the case.

The USB flash drive type miner is very limited in terms of current (power) if it have to be USB 2.0 compatible

But these days, who says its current rating has to be USB 2.0 compatible? That has been extended so now only the link speed for 2.0 is relevant.

Forget thee not that the power needs of tablets, GPS devices, and smartphone has blown away having only 500ma available. Many now need at least 1.2A or more to properly charge and even more to be used while charging. Given that stickminers fall nicely into that extended power-hungry group, strict USB 2.0 compat is a non-issue.

Truth be told, I haven't signed anything with anyone at all. But at the same time I figure it's probably more polite if I don't go blabbing everything that's going on.

I agree with you 100% and is the most professional way to do things.

The way things seem to go in the chip mfg world it is far best to try and not fuel rampant speculation by tossing out tidbits that are too specific. The knowledge that somethings are in the works that may or may not pan out is enough for me.

If the chip suppliers care to speak up eventually -- that's their bailiwick to feed the Forum crowd. After the Bitfury 16nm thread debacle and others, I can understand suppliers being very very careful until chips are in-hand, ready to be delivered.

I completely understand.
I'm under NDA with design team myself ( signed one ), but only one 16 nm chip here.
I do not know what contract they have with the chip manufacturer

If I'm under an NDA, could I correct you if you were wrong?

lol. That's creative. Any NDA specialists here?

Two different 16 nm chips you say.
I suspect you are under NDA, but if I speculate and say this might be Bit fury and Bitmain.
Correct me if I'm wrong.
So from here you steeped on ground level 0 at least

heck even if he doesnt build em we are either already here or will be.

My gekko sticks are the only miners I still have running. Cool

If I ever get to production, I'm thinking of offering a "core exchange" kind of thing where you'd get free shipping on a preassembled unit if you send in a retired miner. That way I could continue to offer preassembled units to people who didn't want to do the swaps themselves.

But we'll see. Right now I'll be happy if I can get a stickminer going. I'm waiting for one outfit to send me some datasheets so I can at least start hardware design.

I've got most of the power and controls at least conceptually ironed out, but not the specifics yet. I need to start playing around testing regulators and whatnot.

Between my own, and yours, and stuff I've picked up from others, I have about 50 chassis between S1, S3 and S5 to play with.

I have 4x S1 and 4x S3 that I have been saving just for this project. I figure that nobody wants them anyway except for maybe you sidehack, but seeing as shipping rates are unreasonable to ship whole units from me to you that is not an option. Besides, this project could take off at any moment, there is no harm in my holding on to them.
