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

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 would be great if Gekkoscience could come up with a 16nm ASIC miner , we need more competitors when it comes to bitcoin mining.

Sidehack,

I would like to have some S1-S3-S5 upgrade type of board.

that's my preference.

Thanks ;-)

Even if the boards were only 175 watts each that would be fine. Space isn't really an issue for most home miners.

I'm gonna shoot for 220W stock, but like everything I intend to design, it'll be adjustable up and down.

Also...

Should we bring the 1BURGER address back into play?

I like the smaller wattage idea.  But it's still in the realm of not being too small.

And, sure, post the address, I'll pass some your way.

I'll donate as well. I've got 25 S1s and over a hundred S3s sitting in the scrap pile. Be happy to put some of it to use.

I pushed/donated some hash rate to the Burger fund on Eligius a while back but they are experiencing quite a long run of bad luck right now. Maybe you could point us to a different pool with the Burgerfund that isn't your testing channel?

I don't have much in coin at the moment, but I can easily/quickly set something to LoadBalance and FailOver.

Sorry, I'm just one guy and I've already discussed three distinct design projects for miners, on top of everything else I've got going on.

Now if I end up able to make the S1 refit boards, four of those on a C1 chassis would probably hit 1000W. Or pack 'em in a rack case and hub 'em together for like 2KW. You know, whatever. But a standalone 1000W miner is not on my list.

A S1 refit or any 250W board would be sweet.

Is there really that many S1s still floating about?

I've got at least a dozen here. But when you consider the mountup is the same for S1, S3, S5 and C1 waterblocks that becomes multiple buttloads. That being the case has been kinda central to the point of the project since it started.

EDITED: 1BURGER...is sidehack's address where we sent burger type money in mining development support beforehand.
how about sidehack reactivating 1BURGER... (as he seem to suggest in prior post, most people probably cannot find it as it was 1-2 years back) for people who would like to contribute burger size (or 2-3  Wink, etc) donations for home miner or two-three chip super stick (?) development and use 1Gekkosci.. address for potential partnerships and larger size donations/collaborations?
This way, 1BURGER is clearly just pure donation and 1Gekkosci could be used otherwise.
Thoughts?

I'm gonna shoot for 220W stock, but like everything I intend to design, it'll be adjustable up and down.

Also...

Should we bring the 1BURGER address back into play?

The 1Gekkosci is my address, in existence well before the 1BURGER was set up. It's been used for general stuff and mining payouts for quite a while now.

The 1BURGER was set up specifically for donations toward miner projects and whatnot, so Biodom's point that it's more appropriate makes sense, but either could be used.

I'm thinking a 2-chip stick would be best. It'd be pretty well on power scale with the BM1384 Compac, and overall the same size since I could put both chips under a heatsink of the same dimensions.

I've almost completed the pod layout (put about six more hours on it today, but didn't work yesterday since I hadn't had a lazy day at home in a solid month) which includes selecting parts and pin assignments for the controls system. Most of the parts I picked, I have SOIC or DIP versions of already on hand so I can start working on code on breadboarded mockups more readily while waiting for PCBs. Since the controls are already designed, shifting them over to a 1/2-chip test board should be pretty trivial; this would make piecewise testing easier and compress down to a stickminer easily.

The pod is laid out for 11 chips, since Bitfury's comm multiplexer is designed to handle that many. Designing a larger miner will be a matter of stacking more 11-chip sections onto one board, probably 44 chips total. Controls will be nearly identical - software will have to know there are more modules and be able to relay to them, but that change will be a fraction of the difficulty of setting up a single 11-chip module with the full sensor package.

The pod (project name Amita) as it's designed now will be able to measure temperatures from the heart of the chip field so it should be more accurate than, say, the S5 sensor on the backside of the middle of the PCB. It'll be able to measure total input power and the string voltage, adjust string voltage in software, and drive a 4-wire fan with speed measurement.

The TypeZero board (S1/3/5 refit) board should be able to do all this as well. No guarantees yet if it'll read input power, but string voltage measurement and software adjustment, fan control and probably multi-point temperature sensing will be there for sure.

Punin of BitFury has mentioned several times in the past about helping out with this project; he got me sample chips and datasheets, which is more than anyone else has done in a while. I'm hopeful about continued support, but in order to prove to BitFury that working with us is worth the trouble, we need to make sure this project stays visible and the interest the community has in its successful completion is apparent.

And, as requested, donations to help support things can go to 1BURGERAXHH6Yi6LRybRJK7ybEm5m5HwTr
