A video from another hobbyist : Solar Powered BitCoin S3 Bitmain Miner FREE BTC! https://youtu.be/NnMsoHMCdkwJust wanted to share and keep you interested. Thats really cool, but when i did research, the prohibitive cost was the yearly upkeep of short lived and expensive batteries. I would love to learn an alternative/cheap way to store power, however.

I saw this on the forum earlier today too. But why is it not showing up on the bitmaintech.com site?
Not that I really want three S5s strapped together anyway...
It's apparently on Bitmain's China website. And indeed, there isint much attract to the home miner. Personally i'm just imagining 6 stock S5 fans screaming at 100% speed. Yeah no thanks.

I don't see these credit card companies lasting long 20 years from now, Cryptocurrency will wipe out master card and visa because the interest rates are low. It's only a matter of time.
They won't go away just because crypto currencies have low fees. They will just create their own blockchain at some point to get all the benefits from it without losing any control. What does them having a blockchain have anything to do with it?

I just bet its not possible even if they technically wanted to, since it would be just a disassembled package of a complete S5+, minus a fan?
The upgrade kit was designed for just shipping the new board, as its light, without having to reship the heatsink, the heavy parts, etc.
Ok have it your way.... But let's just look at this a different way. If S5+ hash boards were made available, as opposed to a complete 3 Bay S5 which is of no use to a Home Miner, then assuming firmware & interfacing to an S1 controller board was possible, which I suspect is straightforward as the interface to all of the BM series of chips is almost identical, then I think there would be a lot of interest. If instead of a form factor of 3 S5 you had a "S5+' with the single form factor, then you would be left with a more expected upgrade to a S5, that still use different frame and heatsinks, enclosure, etc. The difference would be small, a bit like the S3 and the S3+. It would have pretty much the same efficiency, just more under volted chips. Ultimately more heat crammed into the same space.

I was not suggesting that the S1 heatsink would be used, but that the S5+ hash board would be supplied complete with heatsinks. As to the controller an S1 to S3 converter was relatively straightforward, so why not an S1 to S5+ converter? Yes you need a lot of air pressure to cool, but no more than the S5+ requires and fans are relatively cheap. I also realise that this is not going to happen, but I bet technically it could if they wanted to. You were suggesting an S1 to S5+ upgrade. If you need to change the frame, the boards, the heatsink and add fans and a controller adapter. In the end the only thing you would be keeping is a single fan and maybe the s1 controller. So what exactly would you be upgrading? I just bet its not possible even if they technically wanted to, since it would be just a disassembled package of a complete S5+, minus a fan? The upgrade kit was designed for just shipping the new board, as its light, without having to reship the heatsink, the heavy parts, etc.

I can see that an additional fan would be needed but why a new enclosure and why could the controller not be upgraded? Surely the interface to and driving any of the BM series of chips cannot not be that different?
Look at the picture, the chips arent being cooled the same was as before, the S1 heatsink would probably not be of use. You now need to put alot of pressure and air flow on the individual aluminium heatsink and there would not be any with the way the S1 is designed.

I think it would be great if the could offer the S5+ hash boards as an S1 upgrade with new firmware for the controller board?
Rich
You would most likely need a new controller, the boards, more fans and an enclosure and then just maybe you would be okay for dissipating 1200watts of power.

The heck with this 3 unit set of S5+'s for practical use. I just want to be able to get a S3++, or one of these single S5+ miners.
thats what im saying, bitmain is missing the market here.. make a 16x2 BM1384 miner, that pretty much copies the s3 in case and fans. they would use less power then the s3 and ultra quiet.. according to the chart on the first page, a 16x2 board machine running the 13.75 would be 440 GHS @ only 150W Hahhhh.. Sadly i have to disagree. This is exactly hitting the market. Home mining is mostly dead in scale. There is little point working on highly optimized technology for maximum efficiency yada yada. Why make a high tech miner and mass produce it, when its just going to devalue their own mines. Why spend so much time and money comming up with technological edge ASIC? Its much more efficient to mass produce cheap asic and slap them on electricity at 3-4cents/kwh. Too bad for people paying 8+cents/kwh is probably what they think. ^_^" China style. Cheap Mass Production.

I doubt those are all the headsinks - with the S5, they actually experimented with those very same heatsinks. They go on the opposite side of the main one, so I imagine that's the same with this, just a bit of extra heat dissipation on the opposite side of the board. More than likely inside there you have a big headsink similar to the one on the S5 bank to back to back with each board. In terms of the S5, the density is basically 2x, since each one of these blades are the same hashing power of one S5...
Ah its using, allegedly, mini aluminium headsink and a high air pressure is blown through. Dissipating the heat is quite possible since it would obviously use something like 6 of those fans S5 uses. The chips would run hot but thats probably okay. Anyways on the bright side, the diff won't go up TOO much.

Pretty bad ass unit, but like philipma1957 says it's hard to justify that price with the additional costs of importing to the US and psu costs.
yeah I like it but it is over priced. and if this is really a bitmaintech s-5+ why did they not list it first? I would think it is a loud machine 6 fans for 3400 watts will need serious speeds. I would imagine it is a screamer! And, I guess it is similar to the S3++ which unless you live in China there is almost no way to know about them, or get your hands on one. For all we know Bitmain has been implementing the S5+ over a couple months, and that is why the used S5 units are being sold off completely now. I don't really see the upside, the performance ratio is in the vicinity of S5's albeit more compact. Sound like the same chips but a better board. I think its too much heat packed in so little space. People kept arguing me but i still believe this is far from a home miner, and its not much of a upgrade. Its just centralized mining optimized.

Someone once told me that we should prefer the job that suitable with our liking even the salary we get is small, than get depressed in high salary job which force us to work everytime. But, I'm still not ready to go full time on bitcoin although I like it.
if I dont , where the work is paying me a bigger, that I would choose haha There is no point in getting a higher paying job if you're going to hate your life for it. I have a friend who has a hard job, he works overtime and make 65k per year at 24 years old and he hate his life, never have energy to do anything fun outside work hours. What's the point?

No, the file is completely safe, 0 detections out of 63 different virus scanners, except Norton.
Norton is complete crap, and I dare say, a virus itself. Please install a better anti-virus.
I have to second that. While Norton is in the most expensive Anti-Virus out there. It is also in the worse. For scanning malware i recommend Malwarebyte. S&D isint too bad either.

This turned up in the S5 thread: S5+ 432 chips, 7722GH/s, 3436 Wt Have anyone heard about it? Looks interesting. I would like to see some source. The member who brought it up did not mention any, he just threw some insane specs in and left.

Thanks Hedgy!
I was like, Wait a second when did i post that!? lol
No problem buddy I haven't seen such a blatant scam attempt for ages. It is the 3rd identical scam/scammer i saw in the last week. Be careful everyone!

I don't see them making a rack-mount miner from the chips to be used in the S7 and calling it an S6.
You're not seeing a S7 either. They did not announce either yet. Only that the next thing to be released will be the S7.

It was working fine yesterday. Now i tried in safe mode, checked with no firewall, still doesnt work. I added port 8333 and it is properly opened, but that doesn't fix it.
Whats up with MultiBit HD suddenly no longer connecting?
"java.net.ConnectException: Connection refused: connect"

Meh, it's only 15A at 240V xD It still just does not make sense. Look at the design. You want that to dissipate 3500 watts of electricity? xD That's like 2 ovens. I don't know, maybe its some 6k rpm fans and the unit would actually come with 6 fans. Maybe it could dissipate all that heat. It just doesn't look like a home miner.

Where do the specs cited come from? That's not what one would expect from Bitmain. Unless they are giving up their small form factor for more big mine oriented ASIC. That would further favor hash centralization however...
why would you see a 7 to 8Th/s rig as oriented to the big miners / farms given the growing network hash speed? I actually think it brings the home miner back into the game, and the form-factor is only 3x that of the S5 (at tiwce what you'd get from 3 S5's in hash-speed). Problem is, most home miners are Watt limited, not space limited... this purported new S5+ miner doesn't make sense.... unless the SqFt of housing is WAY higher than the USD/(KW/h * 720h) then it plainly doesn't makes sense. Because that machine would not be be favorable to 110v 15a setup from over here. It favor 230v and centralized power for high output farms. The wattage is insane and the efficiency seem to be on par with current S5 chips, so it just seem like 3 unit stuck together.

Estimated Next Difficulty: 52,706,741,888 (+0.82%) Adjust time: After 101 Blocks, About 16.7 hours better than what we got at the beginning, almost +5% Look like this is clearly within the 0.01%-2.50% philipma first allocated to me The hash on the chart is still going way down so it look like we're looking at a still lower difficulty than 0.82%.

I hope that is a personal mod and not a real thing coming from bitmain as it would be quite the disappointment instead of a sleek S7, I am done with the +'s. Um, yeah. Definitively. I want something small factor and easily modable (sound wise mostly). And ideally something stackable. And this is definitively not what i would be looking for...
