If only I could purchase boards and put the tons of prisma parts I have in my warehouse to use.

Or even S1 hardware.

Prisma is on our list of things to work on, if we can get the stickminers and S1-upgrade boards going. How many Prisma parts you got?

Not really THAT many, but it's taking up space.  I have more S1s though.  A form factor that would fit either would be awesome.  Recycling the parts that are too heavy to ship efficiently would also add resale value to the old hardware and cutdown on production costs.

A formfactor that would fit either is approximately impossible, or at best it would be heavily mediocre on both platforms. I'm hoping we have the resources to make Prisma refit boards, but then I'm also hoping we have the resources to make a batch of stick miners so who knows.

Yeah the dimensions are close but off in ways that you can't really reconcile without totally re-drilling at the least- and even then it probably would not fit as well as you would hope. 

Most of the development so far has been sidehack's show but today I etched a breakout board for prototyping the Compac/Amita buck circuit.  Parts for it should be here some time this week as should the test boards for the BM1384 breakout.

Quit killing my dreams guys.  


Edit:  I think I just realized... when I said either I meant either as in "one or the other" not either as in "both."

Oh. Righto then. Our primary goal in this project is to make a set of boards which can be run independently but also mounted on an S1 chassis. A secondary goal is to make a board which would mount on a Prisma.
The stickminers are basically making a product out of stages we'd be at during prototype anyway, and also since our stick miners would be pretty nifty (which is to say, possibly the best stickminers in existence at present given the efficiency and feature set) and also not terribly expensive. But the primary goal is TypeZero boards.

Pretty unlikely since they already have them designed and prototyped. It'd be a FIFTH thing for me to work on.

But if they bail on the idea, I might look into it.

Well, I wasn't thinking of using their controller/backplane and what not.  Just the heatsinks and PSU and maybe the case, however we can jam the Type0 in there.

Oh. Well the problem with that is TypeZero boards in that size neighborhood would probably stock at 250W or so, and the S2 heatsinks are built for 100W boards.

The controller is a BeagleBoner so all it'd require is a different OS image to make it do different things, and the backplane is already wired up for blade comms and such, so an upgrade kit is really not that intensive to pull off. I was thinking about it for a bit but Bitmain announced initial info for their probably-already-completed design when they had prototype hashboards on display at the conference three weeks ago and some. Once all our other projects are done, if they get as far as manufacturing, I might look into building S2 boards with the next chip  - by the time we get to it someone will probably have released a chip better than the BM1384, whether it's Bitmain themselves, Avalon, a resurrected ASICMiner, who knows.

Keen to see this go all the way.

I think there are much more S1's around on total

Seems likely, which is exactly why

An S1 board alone would make a good quiet desk miner, and four a sexy S1 upgrade. But the Prisma refit would also be a good blade in a larger unit, so there's also a dual merit to its design. But it's not priority. Speaking of priority, I might be back to Compac design tomorrow and will probably be able to get a finished first draft of the whole board.

Undoubtedly, let us hope the price of BTC cooperates at the time the boards arrive in the buyers hands.

Oh, hey there bick. Didn't recognize you with the new haircut. Looks like avatars are working again? As for the coin price, I highly suspect it'll drop several percent by this time tomorrow because it's invoice time and every time we get invoices paid in coin the price bottoms just before I have time to cash out.

So, not like I told it?

I wonder if that's a bug in the system, or a deliberate prank (on account of today is April 1st)?

Apparently there's still some issues with the Avatar thing - should be fixed tomorrow (see Meta)
