6.375x6.75 inches

So these wouldn't fit on my S1 heatsinks then, it doesn't look like.

I'll probably end up designing the ArchetypeZero to about the same width as a TZ S1 board (so half width of an actual S1 board) but it'll be longer/taller and screw holes in different places. So it actually would fit on an S1 but you'd have to redrill the heatsink or figure out some other way to attach it. Unless... I put S1 screw holes on it. Which might be possible.

I would say that anything you can do to make it as close to a plug-n-play swap with an S1, the more you will move when resale time comes.

To fit lengthwise in a New R-Box with proper heatsink coverage but still allowing connectors to reach the case penetrations, the board would have to be about 3/4" longer than the height of an S1 board. So that extra would stick out the top. The actual TZ S1 board would not have this extra height (since for that application it'd be an unnecessary additional cost. An actual TZ S1 board would probably space the chips out a little more, as the allowable chip-field (limited by the topside heatsink dimensions) is about 3/4 inch narrower than the space allowed with the S1 heatsink. Since the S1 doesn't have dual-side heatsinks, a lower chip density is preferred to allow good spread to the heatsink.

If you ever offer compac pcb's & solder paste stencil for diy hobbyist/enthusiast/bored people count me in for sure. I NEED to do something with my dead s5 boards.

[AJRGale]

change of subject, Sidehack, you don't have any HP Server PSU break-out adapters? the type that is the PCB as the connector tong, not the metal blades?

[sidehack]

First, a change of subject from BM1384 projects to server PSUs is somewhat inappropriate for a BM1384 project thread. Second, I'm really not sure what you're asking for. Send a PM. Or actually you should PM pmorici since he sells breakout boards for HP PSUs.

Hey sidehack with all the last post, Im a little bit lost 

What is the road plan?

You will produce stick and S1 upgrade or you change your mind ?

stick ------practice r-box board with BM1384 chips --------- S-1/S-3  with newer chips then BM1384

I think the above is the newer plan.

But also not completely sure.

[sidehack]

Yeah that's about right. Whether I build more than half a dozen of the R-Box board will depend on if people want enough of them to make an actual batch, but the TypeZero for S1 and stuff are still a focus. Thinking of the R-Box board (ArchetypeZero?) as a practice run is pretty accurate.

[valkir]

Good thanks you for the clarification

Just a minder post that I'm sure you and Novak are aware of. https://bitcointalk.org/index.php?topic=294499.0

Yeah you right, should of PM'ed 1st

A lot of the protocol-specific stuff is Bitmain-dependent, but we're working on figuring out a way to detect devices accurately without making existing drivers any more convoluted than they already are.

As it sits right now.

I want 2 sticks, cuz' they're cute and to keep/run for posterity.

Currently have 10 S1's (20 hash boards) that are cold and dark and need to be upgraded to something cost efficient.
The S1's are currently listed for sale on eBay, but the closer this project gets to having a viable S1 replacement/upgrade board the faster I'll pull the listing.
Also have space available on several S(odd) waterblocks in the farm (~5 hash boards).
And will want additional hash boards for 2 phase immersion cooling testing (unknown quantity total, but at least 2 to start with).

If the S(odd) replacement/upgrade boards are BM1384 based or whatever based, that's fine with me, as long as that board runs at or below .5W/GH/s

Also have 3 dead Prisma boards whose hash will need to be replaced with something more reliable.

Have been holding off buying new hardware because of this project, Bitmain has not yet released their new product(s) whatever that may be, and Bitmain has no available S5 hash boards and controllers for sale.
All things being equal, I would prefer to purchase from GekkoScience as their designs are typically superior, thoroughly tested, obsolescence resistant, and as such represent a better "bang for the buck".

We need to be buying H/W, ideally something that is physically compatible with the Bitmain S(odd) product line.

Ain't phishing for a deal, just stating what our business needs to do to continue growing and remain profitable.

It's amazing just how relevant that first post is, considering that it is nearly Two Years old.

So, valkir is looking to put together a Group Buy for Canada. Should be a good deal for Canadians because I can ship one box full of sticks across the border for a lot cheaper than I can ship a dozen sticks do a dozen diffrent people. When I announce the sales opening, I reckon he's gonna put together a group buy thread for Canadians to put in orders and then put in the total order with me when orders officially open.

How he handles it is up to him.

On a second note, some of y'all have seen discussion in the New R-Box thread about doing another stage of test build. Given weighing the benefits of cost and ease of assembly against studly awesomeness and whatever, I'm going to try to build a four-chip board that'd fit on a pod heatsink (like Gridseed or U3) that would test most of the driver support and systems we'd need for the TypeZero. Might sell it, might not have chips. Bitmain hasn't gotten back to me yet about anything.

Amita development is continuing. I've got a completed PCB design that has yet to be verified, and after some discussion with Novak I think I'm gonna switch up some of the USB interface parts to make driver support easier. This means additional testing because I'll have to build a new USB adapter and fit it to some of our two-chip test boards so we can confirm basic functionality and make sure drivers behave as expected. If the tests work, it should make driver coding easier for the Amita and future boards.

this board you can make a standard intel or amd hole layout so those without those r-box heatinks can just use the intel or amd one?

i dunno if it would be easy or not?

[sidehack]

Dunno. It's already gonna have some interesting requirements for two or three different shapes of topside heatsinks and screw holes. Not likely I can make something that fits all those requirements and a standard CPU cooler.

once you build a 4 chip board I may be able to get a simple 120mm by 120mm heatsink to fit it.


maybe I will buy this

I can always toss an amp into it instead.
