Would anyone be terribly upset if I did not build a stickminer around this chip? Interfacing to the ASIC directly kinda sucks, and the minimum buck voltage is at the top end of what's likely the practical range for the chip.

It'd be better to use a proper interface chip, but that's kinda wasteful without multiple ASICs. Of course, multiple ASICs also adds to the cost. Doesn't double the cost of course. I don't know how much it'd add.

So, what's a general consensus - a two- or three-chip stickminer (for, say, nominally $35 or $40 versus the original Compac's $25) or no stickminer at all?

sounds like a great idea. I'm definitely interested. the compac I have is still hashing away mining dust, but contributing none the less.

It'll be built off the well-tested BM1384 Compac power design, with some improvements to improve stability at extreme overclocking, and with an entirely new controls set that should allow for temperature monitoring and software voltage adjustment.

Oh boy, cant wait to see what I can do with this. Had a bunch of fun pushing the 1384 compac with that huge modded heatsink with a fan. If you can build it....I can push it to the edge! GL

I refuse to make anything with fixed specs, so a USB miner would be downvoltable and downclockable to run on a stock USB port. Because of buck losses and control overhead it won't be at its most efficient operating point down there, but it should still run. The BM1384 Compac could run off a 500mA port, or it could be pushed to 2.5A if you wanted.

Yeah I'd shoot for a stock power draw of about 220W DC per S1 board. When you figure in the fan and stuff, and PSU losses, you're looking at a bit over 500W wall. So not as quiet as an S3 but certainly quieter than an S5. I also intend to put PCIe jacks in the right place to still be compatible with an S3 housing. USB cabling internally will be the only worry there.

Nobody ever said a 250W board doing 10TH. That kind of thing is probably two years away at best.

I know just talk i wouldn't care as long it would be worth using not priced like bitmian shit and i know you can make it run better you have .I never said you said that

. Just talk

I wish had could get a good supply of Chips . i don't btc farm directly any more but would if he could get the chips , I gpu mine now , and doing good .

Same here,3 380's & 1 390 mining eth & other coins

What's going on in China? Huh

I miss something???

crack down on BTC they can't trade in china with the big banks and money processor, citizen are a loud to have coins but trading them might get them in big trouble. it sad to be under that kind of controll i'd rather have high prices and be free then be told i can't do this or that if i do im killed or much less locked up .

and my little GPU farm is growing i getting one two more at the end of month 3 RX470 2 R7 370 i kind of got Swed on, I trusted some one I could have two 4 gb for the same price, one r9 280 that's the impressive one it all most does what a Rx480 8gb does no lie with silent army kernels, I'll mine Zcash til it dies if it does then back to ETH by die drop below eth prices and settle at xmr prices .

My preference would be 250watt boards for the old S1's. I'd think that would give the most cost effective deployment possible.

'

and does 10 th i would invert in two or three but that's dreaming now with what may happen in china, i always knew the GOV controlled it all there, but it's worse then i thought .

I'll be working up a test board which is effectively a 2-chip USB miner. If it works well enough (and can be cost-effective) I'll look into paring it down to a usable stickminer size, ideally same as the BM1384 Compac. Two chips would put it in the same power range but with probably 3-5 times the hashrate.

Sounds very interesting, would such a miner require a more powerful USB port? I remember one Bitfury-based dual-chip USB miner a few years ago that didn't run for me because some of my USB ports didn't provide sufficient power. Still, I love dual-chip designs, and even if it does need a stronger USB port, I'm willing to fork over more money

No, the auction sticks are a real thing and will go out in the next couple weeks.

Sweet, got a tad confused. But yes a multi chip USB would be a great addition to the USB collection. Ill have to change the current setup now though Roll Eyes

Multi-chip USB stick is good for me aswell. Grin

Does that mean the auction sticks are now a no go? Would the equivalent value be put towards the new USB sticks?

Hello. This is my first post in this forum.

I do not care if I get multiple sticks or one pod miner. I'll take what will come sooner. So for me, if the stickminer come sooner than pod - Build it!

what is this "brake pedal" you speak of?

2-3 chip stick miners works for me.

Evil beware: We have waffles!

I vote yes for the 2-3 chip stick as well.
As you said it is the least $$ risk for you, good for the community, and at least would prove to BitFury that you can do it right.

Yep, you've been pessimistic about it for months. Noted. I, however, choose the other route because it's simultaneously gonna be awesome for the community and I don't go bankrupt if I'm right.

So anyway. The stickminer question. Let's discuss that instead of everything else that's already been rolled over a couple times.

two-three chip running 90 to 140gh correct?

please build it
