It's specifically like the 5-chip Gridseed units, which the guy was discussing. Someone posted a picture of that 32GH R-Box on the previous page, and yeah they're built pretty similarly but I don't have one to take apart for actual comparison.

The "New R-Box" is basically half an AM Tube board. It's got four VRMs (TPS53355) with three BE200 per, voltage and clock pretty much the same. I think the volt-setting resistors on the buck circuit are even the same values but I could be wrong, been a while since I looked that close. Yep, it's really hard to talk about Rockminer products since they all have pretty much the same name.

r-box-little = older smaller one

r-box-big = newer bigger one

You know...

A 3x2 of BM1384 would run about 45W (including fan and everything) for 100GH. But with the top heatsink core as narrow as it is, 4 chip is probably the only real option. Amita regulator with a bit beefier inductor could easily drive a 2x2 of BM1384 and get you 85+ GH off less than 50W, down to around 30GH off probably less than 12W all in. Just uh... just throwing that out there.

This sounds a lot like the "Original R-box". That was a roughly a 4" cube with a fan sitting on top. It had 4 chips under the heatsink, and think they were BE200 ASIC's. This was roughly 32GH and maybe 40W at the wall with a 12V brick. I expect that the "New R-box" was essentially a different board with the equivalent set of parts from three of the "Original R-box".

It's kinda too bad that Rockminer re-used the name the way they did.

Anyway, If I could vote for which form factor you should reuse in this small miner market, I'd say try to make a Bitcoin only miner out of the old Gridseeds. There are an abundance of those in the wild from my understanding, since it was one of the first scrypt asics on the market. I personally, have about 150 left.

Is rockminer still around... I can't find their site Sad

.

They stopped selling products early this year, went cloud mining contracts.. think they pretty much disappeared when all the AM drama started. rockxie hasn't been on since early March. Continue discussion in rockminer thread? https://bitcointalksearch.org/topic/rockminer-miners-using-gen3-asicminer-chips-528464

Perhaps, how hard would it be to do is the question.

If I was going to do any production of these I'd have to get more chips. I've already emailed Bitmain about the possibility of getting more chips (which I was wondering anyway in case Compac/Amita sales were ridiculous). When the idea for this board was proposed, a one-off run was asked for which means a single batch of a few hundred boards, which I've repeated a couple times. The point is not to make it compatible with an S1, but to make it compatible with a New R-Box; S1 compatibility is almost a side-effect of convenience on my end. If you want a mass-produced product to stick on your S1, you want this thing's big brother the TypeZero Spec1 - which this thing would act somewhat as an initial prototype for since the base design would be almost identical. Depending how timing works out, I'd rather put new-gen chips on the TypeZero once some are known to exist. If Bitmain doesn't give us any info, Avalon might.

So, yeah. What Phil just said.

Ok, clear, thanks!

Just had a thought about selling my 2 remaining New-RBoxes these days but now I will wait a little longer and watch this thread Wink

You have some free action for a while.

I saw a really nice heat sink for 12 bucks on ebay. I think I will get it and just hope these get built.

If I'm not able to fit S1 holes on it, they'd still fit on a redrilled S1 heatsink. So, anything you could mount a standard S1 board on would fit two of these side-by-side.
Yes, it'd have a PCIe for power and a USB.

And you'll loose all the buyers who wants to buy in quantity....

I think nobody will redrill 100 or 200 pieces of S1 or S3.... Redrill and make the screwthreads.... Not a good idea.

but he has 1000 chips with 600 set for usb sticks this leaves only 400 chips left.

these boards are 18 chips so we are not at a quality point.

of course my numbers may be wrong on chips.

Ok got it.

This stuff is not for mass production. Angry

I am thinking sidehack is looking forward to a second set of chips maybe BM1386 for the new s-7 not sure.

This r-box is more like a practice step. Have to wait and see.

Someone requested New R-Box form factor and it's close enough to something I was already going to do that the idea seems appealing. If I wanted to make a new Gridseed, I'd be making a new U3.

Dang, I was hoping to get rid of these things Wink

Yeah I am in for a few. I will make my own design with parts lying around and the 18 chip boards. should be fun.

I have a New R-Box that I would like to upgrade.

Any idea on the cost of the board?

I have a lot of heatsinks

I used to build amps for musicians

and audiophiles

these are about 6 by 12

I can drill them to fit the chips and put two boards on it.
heck If I figure out where I put them i could use 1 per board. would be quiet.
