Put me down for:
1 - BM1384 stick @$30
1 - BM1384 pod @$70


1 - BF16 stick @$40
1 - BF16 pod @$125
2 - 33-chip BF16 refit boards (maybe more when you have a price figured out.)

I was going to reply sarcastically with a search result, but searching let me know I hadn't actually said much about this in a while and a lot of things have changed since then.

The heatsink has not changed since then.

I gave up on CPU cooler compatibility a long time ago; it was an okay idea for a while but presented way too many problems to really be practical. From now on I'll be working around an 8cm square heatsink, atop which will sit a standard 2/3-wire case fan.

The pod is designed to be 12cm square with mounting holes at each corner for an enclosure or tower stack standoffs. It will ship with rubber feet adhered to these corners. The heatsink will be screwed on through an aluminum base plate to help maintain planar contact of the chips underneath. The pods will take in USB from either a Mini or B plug, and will take power through a barrel jack or PCIe 6-pin. There is a second 6-pin for daisychaining power to multiple boards from one master cable. All these connections are lined up along one side. On the manual-adjust pods (short-term plan) there's also a small potentiometer which can be turned to adjust core voltage. BF16 pods will implement software-adjustable voltage control with internal calibration.

What will be used for cooling on the pod?  Standard passive CPU cooler by chance or will that be up to the individual?

Because of buck overheads and other things, the low-end hashing efficiency of the 2-chip BM1384 would only be at best a marginal improvement over the existing Compac. However, overclocking is where it'll really shine. The old stick's 5W performance was around 12GH, where 15GH is hopefully a conservative estimate for this one; 7W should see over 20GH instead of 16GH and the top-end 10W would get you about 27GH instead of the old stick's maybe hitting 20GH if it didn't burst into flames. Cooling should also be better because of the reduced heat density of two chips.

The pod, as it's laid out so far, is about a 5" square. I'm making both versions with the same formfactor for convenience, if someone wants to make enclosures or stack 'em into towers or whatever. The same hardware should work for any of 'em.

Heard a bit from VH earlier, he's making progress on the 1384 code. I'll be at the shop tomorrow doing some more testing and getting him some more info, but it's looking really promising so far. Code's a bit behind schedule but it was an optimistic schedule anyway, and I gotta take the blame for a lot of it for not getting hardware setups and some necessary testing done in a timely manner. Course there's also approximately zero documentation so that doesn't help. But if good news keeps coming to me at pace, I might have some good news for y'all in about a week.

Definitely interested in both the short term projects now- stick looks like it won't have much room to overclock on 5w as most usb ports can only manage that much, but more efficiency is always welcome. Pod looks very interesting to me as it uses much less electricity as most other miners out today, cost is a lot lower than I would have thought on both miners.

He'll be stocking.

Is Crazyguy whatchin this thread? I wonder if he's even still doin BTC. I Hope, So cause I got my 10 Compacs from him.

If you are projecting interest from this thread, count me in for:

2-chip stick using BM1384, wholesale price about $30, estimated 15GH/5WDC - 2
10-chip BM1385 pod, wholesale price about $70, estimated 250GH/60WDC - 4


2-chip stick using BF16, wholesale price around $40, estimated 60GH/5WDC - 2
11-chip BF16 pod, wholesale price around $125, estimated 650GH/75WDC - 5
33-chip BF16 S1/3/5 refit board, wholesale price unknown, estimated 2TH/200W - Likely a decent amount, will wait until you get a better estimate of price.

Details are great, but I'm not taking money on anything until it's proven. I know my hardware is good for the BM1384 2-chip but we're still ironing out the code; there's more documentation on BM1385 so that should actually be easier to work with especially once the 1384 multi-chip is working. Once the 2x1384 stick code is baseline functional, then we can talk.

Plus I won't have actual pricing until the designs are complete. The stick I'm not so worried about but the pod could shift a bit. And BF16 designs will probably be heavily dependent on chip pricing, which will be heavily dependent on quantity.

Additional plus, Phil, I owe you money anyway so you won't be paying for anything until that debt's been cleared.

By the way, the 33-chip will be a single board with 33 chips, built to fit a single S1-compatible heatsink. Most likely they'll sell in pairs but that's not mandatory.

Okay the 2 chip bm1384 USB stick. I want 2 at 30 each = 60
The 10 chip bm1385 pod.  I want 2 at 70 each = 140
     200 total for the short term.

The bit fury 2 chip I want 5 at 40 each = 200
The bit fury 11 chip I want 5 at 125 each = 525


The bit fury 33 chip I want 5


so short term 200
Longer term 725

plus the five 33 chip units.

Pm me if you need to talk details.

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

I have PCB layouts of all of these things already. The short-terms will probably have prototype PCBs ordered on Monday and code is being developed right now for them.

I have a working-model PCB for the 2-chip BF16 which is heavily designed for unit testing, but which on the whole is functionally identical to the final version stick (circuit-wise). The 11-chip BF16 pod will need to be revised both physically (form-factor changes) and, probably, electrically once I've gotten the 2-chip working and ironed out any kinks.

Everything on this list will have adjustable core voltage for both undervolting and overvolting. Undervolting means a longer viable lifetime due to increased efficiency. This is a mandatory feature and I will never release a miner without it.
All miners will use USB interface for ease of control - no proprietary controllers or IO boards are necessary. This is a mandatory feature and I will never release a miner without it.

With those specs, count me in for 2x pods 

The universe gave you fingers so you could type your question.

I am sure the specs of pod, stick and compac are on this thread somewhere but could someone refresh pricing and specs on each proposed model. Thanks

Not exactly the place to be discussing that kind of thing.

Today's a designated odd-job assembly day, which includes the BW sticks from the auction and a lot of test stuff for this project, so I'll be catching up a lot of backlog next week.

So I guess I'll ask again.  Psu'??  Shipping anytime soon @sidehack?   It's been well over a month now.  if you want to just refund me my .5 btc we decided on I'll be happy to do that too.  I honestly thought you would get on the psu much much quicker than this.  Let me know what's going on today please. If they can't be shipped out next week then I'll request my money be returned.

Would love 4-5 pods regardless of price im in Seattle area and it would be nice to replace the s7-LN's that heat my place

I need hella boards when the come out...

That's the next step after the BF16 pod. We set the projects up specifically so about 90% of the driver/control for the pod is also done on the stick, and about 90% of the S5 refit is done on the pod. That means once the stick is figured out and working, we're more than halfway to the big guy.

 Exciting indeed. When available, I'd like 2 of the BF16 pods. Better yet, if you build BF16 upgrade kits for the S5, I'd take 4 boards.

VH, you're the bomb dot com. Sidehack, you're also the bomb dot com.
I'm very excited for this project.
