Anyways, on to the news.

I just did some testing of vh's latest ramp code on a hardware mockup of the 2-chip BM1384 stick and it looks to be working. That's the second of two required software milestones before I was completely comfortable with the project.

So now we have tested and approved functionality of both the hardware and the software. I'm waiting for prototype PCBs of the actual stick form-factor to make sure that specific layout works as expected before sending off for a large batch, but the circuit itself (as well as the code to operate it) has been proven. Technically this is a preorder, but as stated - both the software and the hardware are proven. I wouldn't be saying anything otherwise.

So with that in mind, I'm going to go ahead and open up sales on the 2PAC 2-chip BM1384 stick miner. Total batch limit of 1500 sticks; once this is reached there will be no more. Sticks will be $30 apiece. I can't give a specific estimate for initial shipping because it'll depend on if the PCB layout works as expected or if I have to fix any problems. All I can say is, I hope to start moving them by the end of January.

Donations can still be sent to the 1BURGER address (1BURGERAXHH6Yi6LRybRJK7ybEm5m5HwTr) and I'm adding a sales address to the lineup: 12PACBUYyFhRyhRB4qB9Z5Z8M6E3p8gpmt. I'm still vanity-genning a snazzy loan address, so that's pending.

I'll put up a thread in Group Buys today or tomorrow with all this info consolidated, including estimated specs of the stick.
Any idea on sales times for the pods? Smiley

VERY excited about this news. Going to buy one or two sticks this time, always excited to buy into a piece of mining history. Sticks have also been known to have great resale value Wink

I also am interested on an ETA of when the preorders for pods will start- much more interested in em than anything else.

Pod ETA is an unknown at this time because the hardware hasn't been prototyped. I have a first draft PCB arriving at the same time as the 2Pac prototype PCBs. I have enough stuff around the shop that vh can probably get a head start on coding but until the actual PCB is in hand there's no guarantees. Hopefully he can build off the 2Pac driver pretty easily.

Regarding 2Pac purchases, go ahead and start sending. Make sure to PM me (or email sales at gekkoscience) with your forum handle, shipping address and the transaction ID. I'll start a list like I did for the original Compacs, and probably set up the same queueing structure for large and small orders.

Okay, thanks for the info. Any is appreciated at this point, possibly the most exciting project I've seen since the S1/S3 USB connection boards back in '14. If it's anything like the Compacs, these sticks will sell pretty quick.


Also, about shipping- how much'll it be for the lower 48? Guessing it ain't free, just looking for an approximation.

wait, the 2pac is a 1384? just like the other usb sticks with the s5 chips but with 2 instead of one??

sorry i thought you were making s7 or s9 chip usb sticks.. must have miss read somewhere..



is the pods going to be s5 chips too??

No, the first pod won't be the BF chips, it will be the BM1385 chips.

sidehack has mentioned this several times earlier in the thread.

The short-term projects are

2-chip stick using BM1384, wholesale price about $30, estimated 15GH/5WDC
10-chip BM1385 pod, wholesale price about $70, estimated 250GH/60WDC

Longer-term projects are

2-chip stick using BF16, wholesale price around $40, estimated 60GH/5WDC
11-chip BF16 pod, wholesale price around $125, estimated 650GH/75WDC
33-chip BF16 S1/3/5 refit board, wholesale price unknown, estimated 2TH/200W

Your pictures from earlier are not loading for my browser. Probably doesn't matter as they were proto-types anyhow. Soo to be clear, how is the 2 chip BM1384 powered? Barrel Jack, USB Jack, PCI-E, 12volt or 5volt? I have several Rockminer PSU Power distribution boards but those were meant for 12volt output mainly, as well as the 2 BlackArrow boards that I have.

The 2Pac has always been BM1384 chips, since it would be quick and easy to bring to market and raise money for Bitfury development.

The pod I'm currently working on alongside it is using BM1385 chips from the S7. Whether or not it ends up getting mass-produced is a matter for another day. Hopefully once the prototype is assembled it'll be mostly a software thing.

I have a prototype PCB for a 2-chip Bitfury 16nm miner which is going to require a lot of firmware and driver code development to get working. Once it works I have most of what I need to build an 11-chip pod and a 33-chip S1 refit board.

Once I have news about that, I'll make it very obvious.

Most of the discussion from the last dozen-odd pages has been BM1384 2Pac stuff. The 2Pac has only ever been a BM1384 design, and anyone who told you otherwise was mistaken.

I enumerated everything clearly in this post: https://bitcointalk.org/index.php?topic=1651958.msg17065895#msg17065895

ok cool, i guess ill wait for the other pods.. i already have a few of your usb sticks.. thanks Smiley

i think i was just mistaken and thought you were talking about making 1385 usb sticks..

Yeah for sure. I don't know how much time VH has put into this honestly, but it's been a lot. I've been feeding him raw HEX dumps and kernel logs and he's somehow making enough sense of it to have pretty much completely reverse-engineered how S5s handle chip communications, even some of the hairy particulars. None of the projects discussed in this thread would have gotten very far without his labors.

I understand it's a pain, but maybe updating the original post with data/prices/updates as you go would save a lot of repeat questions? I follow the thread but still miss or forget stuff Smiley

Tuesday is sandwich day, and Friday night is burger night (so the only day I'm guaranteed to take off work by 5PM). Those are the only "days".

Currently, GekkoScience is a one-man operation. Novak got a real job as a rocket scientist so that's keeping him busy. VH is basically contracted, not an official employee. My last cable minion moved to another state so I'm doing all that as well, but I have better tooling now so that saves a buttload of time.

Bulk manufacture of stickminers is a huge timesink though, since there's a lot of testing and assembly and more testing once they come out of the oven. I'll definitely be bringing in some help when it's time to start batching so we can get these guys out quicker.
