Unfortunately you're right, too wide to fit two. If you cut a slice in the side of the case such that you could slide it in with the heatsinked side inside and the connector side sticking out, you could put two in there back-to-back (mirrored, more or less, with one hanging out the left and one hanging out the right side) and still use the fans. But you couldn't just put two whole pods in there.

Of course it has blinky lights! Who do you think I am, a guy who doesn't put blinky lights on miners? Pfft.
But yes, the power LED is blue and there's a white flash when it returns a share. I didn't use the same RGB LED as on the Compacs because it's apparently not balanced, everyone sees the flash as a different color (some white, some blue, some purple) so this just uses a blue LED and white LEDs.

Looking good. Is there any plans for 6pin power connection? Only because ive got lots of 6pin leads left over from various antminers that inwas hoping to use for the futures pods Smiley

Nice! Will the PCB have mounting holes pre-drilled/cut, or is the intent to have one of the heat sinks sitting on the table?

First off, I just said I'd make one with 16nm chips. Second, spamming me isn't going to get anything done any faster. I have the chips, just we're not yet able to make them work. It doesn't help that the guy doing the hardware and the guy doing the software are two time zones apart. As soon as we figure out the last bits to talking to the chips we'll be in business. But since I've been working on designing and redesigning this pod, and manufacturing over a thousand 2Pacs, and doing everything else around here, I'm a shade behind on ironing out the remaining kinks for Bitfury communication. But believe me, once that hurdle is leapt we'll be in business. THEN we can work on getting Bitfury's attention, which shouldn't be much of a problem since they've sworn up and down I'll be able to buy chips.

There isn't a lot of room for mounting holes. You can't really see it from the picture but the board's fairly busy. Maybe we can do something clever with stick-on rubber feet?

For anyone wondering, this is a half-scale pod kept intentionally simple. The fancy stuff like fan throttling and software voltage and six-pin jacks and screwholes for legs or cases or whatever are all gonna be there on the big one. So don't ask if such-and-such feature is gonna be on this, because it isn't.

I've got a 3D printer and a half-assed understanding of most things. If you send me the CAD files of the PCB I can try to whip something up. PM me if you're interested.

Not sure exactly what you're asking for. If you want the PCB layout, no because I make and sell these things for a living and I'm not giving that away. If you want a 3D mechanical something-or-other, I don't have that. I'm very pencil-and-paper. I can tell you it's a four-inch-square 1/16" thick slab.

No, not anything proprietary. The mechanical drawing would have been enough if it was an option. I was mainly wanting to get the dimensions for the cap and anything on the other side of the heat sinks that aren't in the picture. That way I could come up with some sort of air duct system/stand for the pods and know what sort of clearances I had to work with. I might be able to come up with something based off the specs you gave me.

interesting, however, an enclosure might trap heat dissipating by fins, so maybe enclosure around PCB with fins protruding out?
then, it would look similar to some graphic cards.
heck, maybe, once he switches to BF chips, one can envision a "hanging" design similar to what people do with GPUs on metal racks.
then, a big fan could take care of a multitude.

I am working on something now for stacking two or four Superbpag hubs side by side and mounting a 80mm or 120mm case fan on top of them (the image below is for the four hub version). I was sort envisioning something similar for the pods (although oriented differently to account for the second heat sink). The idea being by forcing the air to flow across the heat sinks instead of just flowing in the general direction of the heat sinks we can get better cooling.

http://imgur.com/ze8Q6RE

For those not grasping the idea behind the image, there will be four hubs side by side with 2Pac's in each hub. The body shown in the image is looking from the top through to the bottom. The body will sit on top of the hubs with each of the 2Pac's in their respective walled off area. The bottom is open and there will be a fan on top so air will be pulled from the bottom to the top. There will be an unpictured body that goes on the bottom that will support each of the USB hubs and keep them in place and provide support for the pictured body. I am still early in the design phase so it may be hard to envision.

Gotcha! I only remember you saying about the pods having 6pin jacks and possibly being able to be daisy-chained, that's all.

Going to be nice to finally see a decent pod miner

Here's a breakdown of my "product families":

Compac - USB stick miner, basic control system
Terminus - half-scale basic pod, same basic control system
Amita - full-scale pod, advanced control system
TypeZero - S1/3/5 refit board, same advanced control system

BM1384 Compac and 2Pac are a thing, Terminus is about to be a thing. I don't plan on making anything bigger with BM1384. I should have one of each product made with Bitfury chips, and development will progress from smaller to larger scale since each step builds on the progress from the previous step. The Amita will be the feature-rich pod, with software voltage setting and daisychain power and all the trimmings.

Will the new pod miners work with vthoang's cgminer fork?

Any estimates when Terminus, Amita, and TypeZero will be ready for purchase?

From the first post:

It also already works with VH's current cgminer build.

As for the rest - no. Terminus R808 needs more work as stated previously; BF16 anything is dependent on solving problems and that can't be predicted. Best I can say is, "as soon as VH and I possibly can".

 I've seen a few adapters to go from a PCI-E 6-pin power cable to 3 (or more) barrel connectors.

 Used to be pretty widespread back in the Gridseed "pod" and "blade" days.



 Speaking of which - 2 of these would fit quite nicely on the 80 "blade" heatsinks if they could be attached somehow, though I can't tell if the pod has a heatsink on the bottom as well as the top one.

The pod has identical heatsinks above and below. The top one will mate directly onto the chips, the bottom will have a thermal pad between itself and the PCB to avoid shorting local ground planes (like jumping heatsinks on an S7).

I'll put up mechanical specs on the heatsinks and screw positions at some point so y'all can start playing. The entire bottom side of the PCB is empty except where through-hole components (jacks and whatnot) protrude as necessary, but the topside clearance is pretty specific. The heatsink is 1.813 inches (1 13/16) wide and there's at most 1/8 inch clearance between the heatsink edge and parts you really don't want the heatsink to touch.

As for prepay, I'd really rather you didn't. If the current prototype were up to par I'd say go for it, but since I've had to redesign (and new proto PCBs have been ordered) I won't take any money until the design is proven. The general size, shape and jack placement won't change though so you can start planning around that if you want.

By the way, the hacked-up prototype is now running 300MHz/132GH. In the morning another one will be in the mail to VH so he can improve driver support locally.

Thanks everyone who bought 2Pacs and provided miscellaneous support because that's what's allowed the current pace of product development. Just think what it'd been like if I had VH code and today's resources back in 2015.
