[CLOSED] ASICMiner Prisma 1.4th/s - 1.47 BTC

[Xtra7973]

I keep checking https://asicpuppy.com/magentoPuppy/index.php/asic-mining-hardware.html to see if the prismas are up yet and im guessing beings batch 6 is on hold it might be delayed on asicpuppy. Then I got an email from a site which I wont name and they have them up for 649.99 and they say Available for shipping 11/6 or refund available. Im guessing a bunch of them are on the way to the states id imagine? I wish I would have got in on batch one as I cant wait to get my hands on them.

I should have some listed on the site tomorrow.

I was thinking about making something to transfer heat from miners, it may not be as complex, but by using scrap hydronic heating tubes (copper pipes with aluminum fins) and a pump I could make a system to transfer heat to another area.  The aluminum fins are supposed to disperse heat from water that is inside of the copper pipe.  Basically, instead of using a boiler, you use bitcoin miners.  I would imagine you would need a pump that could withstand the heat, and also you would not want to build up too much pressure. Thoughts?

bobsaq3 and sidehack are spot on at stock/factory clock rates.
We prefer to allow a little more head room for OC'ing the Prisma's and hence have migrated to one DPS-1600BB per Prisma.
OC'ing a Prisma only makes financial sense if the cost per Kwh is low ($0.08/KWh or less).

Then there are the heat dissipation issues that come with filling a room/Data Center with OC'ed Prisma's.
Pursuant to that we are prototyping Open Bath Immersion (OBI) cooling using the 3M Novec Engineered Fluids in custom built polycarbonate immersion tanks.
With the ultimate goal of immersing 32 OC'ed Prisma hash boards, controlled by an RPi w/wireless, in an OBI tank powered by 5 DPS-2000's.
Power consumption should be ~10Kw per tank and dissipate ~32K BTU continuously, enough to heat the average American sized home in a Minnesota winter AND GET PAID TO DO IT.
The residual/excess heat could be used to heat a garage, heat a driveway, heat sidewalks, melt snow off of the roof, heat a pool/hot tub/fish pond, etc. . . . . . .

Our Youtube channel (PlanetCrypto) has some videos of our initial testing.

A polycarbonate immersion tank with 2x Bitmain S3+ hash boards:

We no longer power the fan in the S3+ tank as it is not required for condensation.
The heat generated from the S3+ tank supplements the in-floor heat in our little DC.
We have laid PEX in the ground outside the DC as a place to dump excess heat in upcoming expanded systems.

When we get a 32 Prisma board system up and running we'll post some vid's on the channel.

Awesome videos. If you flipped the 24x boards over it might look cooler since they were designed to push heat through the pcb. You would get lots of tiny bubbles instead of the big eruptions through the mounting holes. It might not be more efficient, but I think it would be cooler to look at.  I want to build an immersion tank as well, but lack of funds is preventing me from doing so. I do have several design ideas though. I know it was a test tank, but if you added a second radiator to the fish tank in a V formation you would get better condensation. You don't want to use fans in the tank because the name of the game is less energy used to cool the miners. Wow, sorry for sounding like a prick. I've spent a lot of time researching and designing a few different versions. It's nice to see someone putting a system together. Yes, I am jealous.
Heating a house with miners can definitely happen. It got to a frigid 40 degrees here last night in north Florida. I have 6 S1's and 2 S3's, with a box fan and relocating 2 miners the coldest part of the house was 68. The room where most of the miners were was 82. My central heat isn't working right now, so that was the miners keeping it warm in the house.  

The tube Erupter tank is disassembled, we were going to jump on those boards but the Prisma's came out (shout out to Crazy Guy for giving us the heads up).
Had lots of ideas too when we got into immersion cooling.
Thank the Bitcoin Gods we spent a day with Phil Tuma @ 3M.
Phil very kindly told us/me why a lot of our/my ideas wouldn't work (mostly cuz' he had already tried them @ 3M's expense).
Saved us a BUNCH of time and money not exploring crappy ideas.

Not saying any of your ideas are crappy, just my hair brained ideas.
V'ed coolers take up too much room in the tank versus mono extruded fin high thermal conductivity copper tube with Turbolators (https://www.finnedtube.com/extruded-fin-tubes & https://www.finnedtube.com/turbulators).
Fans don't survive cuz' the Novec fluid dries out the bearings and they stop spinning anyway.
Fans also dilute the vapor layer and consequently require larger condensation surface area/lower cooling fluid temperatures to condense the less dense vapor.
PVC coated wire leeches DOP (dioctyl phthalate) into the fluid which deposits itself on hot components (chips and copper back planes) and reduces thermal conductivity on the parts that really need it (http://en.wikipedia.org/wiki/Bis(2-ethylhexyl)_phthalate)
PTFE coated wire doesn't exhibit this problem but it's expensive as hell.
Unless the tank is purged of air, eventually, the water in the air will condense out, corrode metal components/circuit traces/solder joints and cause "ghosts in the machine" (bags of silica gel also solve this issue).

The 24x Tubes have a higher board chip density than the S3's.
Bitmain wouldn't sell us chips for our own high density board design (guess they were jealous).
Evidently somebody (friedcat) was listening cuz' the Prisma's have a much higher density than anything else out there on the market (big shout out to friedcat, thanks o brilliant one).
And in the immersion cooling world, board chip density is where it's at.

Suffice to say there are lots of hidden non-intuitive gotcha's in OBI cooling. But once over the learning curve it works like a dream and makes managing heat dissipation a breeze (pun intended).
Besides it looks cool as hell in a clear polycarbonate tank. LOL. We've had visitors pull up a chair and sit for hours watching the bubbles, kinda' like washing machine TV.

I think that would be awesome. I'm already envisioning a tank-less water heater and hour long scolding hot showers. Powered by bitcoin.

Didn't Gavin talk about something similar about a year ago?  He was saying that if/once bitcoin becomes popular and Moore's Law is reached or close, that people would buy a hot water heater, furnace, heater, etc with some ASIC chips built in to earn a few dozen satoshi.

[CrazyGuy]

I think that's definitely a possibility. If bitcoin prices don't start going up, I may be selling Block Erupter space heaters and dehydrators in 2015.

there is money in space heaters.  the s-3 can be down clocked and undervolted you get  380 gh with  250 watts.  it will run quietly.  We have a few older developments with electric baseboard heat.  very costly to use.

so an s-3 will give the same heat per watt as the baseboard will give.

An undervolted downclocked r-box would work  90gh at 60-65 watts. or the new antminer u-4 or is it u-3 I forgot

not happening anytime soon. The cost difference between building a mining system into an appliance vs a basic metal heating element likely exceeds what will be mined in its lifespan. $500 computer wedged into the heater, that runs maybe 8-16hrs/day, or a $20 metal coil? Think you'll mine $480 worth of BTC?

+hazardous materials at disposal
+if you lose your internet, mining stops right? then what - no heat?

thats entirely up to btc's price by then

I think the trick would be to get manufacturers to agree on a standardized modular design. Something like the first rbox that could be easily plugged in to a variety of devices like space heaters, water heaters, etc... This would enable upgrade paths and open a new market for mining accesories.

Someone just created a new business model. Appliances that make you money.

Yes Susie, you can make us dinner with you new Bitcoin EZ-bake oven.

I need to get in on the ground floor of this.

Edit...
Just thought of another one. Bitcoin mining Airplanes. A lot of them provide wifi for passengers, those engines produce a lot of energy, and if they only mine while in the air, what could be better for a heatsink than a 300 mph wind? Crank them up on the ground to de-ice the wings.

Thank You for flying Bitcoin Air.

@CrazyGuy Have you seen movement of the remaining batches and if so do you have an estimate on delivery?

[oner]

I've received a photo of the adapter that has been created for connecting to a RPi. The interface is USB, so that's good news.

https://i.imgur.com/S2sr0zcl.png

I will ship overseas, but I can not estimate a price as I don't have package dimensions. The weight will be somewhere around 8kg.

CG do you know, or have an ETA of aforementioned hardware for the rPI? Also where can we get a downloadable img of the rPI software? i do appreciate the work you guys have been putting into these tubes...great miners!!
*i apologize if this has been posted earlier...i just can't find that info if it has been put up.*

[mrpark]

I set up the controller with BTC guild stratum server, the miner is reporting 1.3-1.4Th/s, but on BTCGuild only reporting 1Th/s? I will try other pools to see if there is a difference. Bitcoin.cz and Ghash.io.

[CrazyGuy]

Yes, they are in the US now. I had to spend some time on the phone yesterday convincing US customs that I wasn't importing time bombs. I will post a more detailed update this evening.

I had similar issues with BTCGuild. They were reporting my hash rate at 1.2TH/s. Are you using the "stratum-lb-usa48.btcguild.com" address? I ended up just pointing it at Gigahash but I'll be happy to get the adapter and RPi in so I can point it at Eligius, my pool of choice.

Well they have to be sure it isn't a terrorist plot to send ebola laced time bombs masked as bitcoin miners.

[mrpark]

Yes to the stratum-lb-usa48.btcguild.com , and I have one other miner not reporting correctly. I have them pointed to the slush pool, but it seems to take a long time to update the hash rate. Yes, I also like Eligius very much.  My miner did not come with the adapter, but hopefully I can get one soon also. Giving it a few hours to see what slush's pool reports.

To an untrained eye these prismas may look like a suspicious contraption with all the chips on the outside and wires and stuff. All you need is a countdown LCD.

Then again, customs once held some of my SP10s which look like bona fide rack mount servers, so I can't pretend to know their logic. "Anything that doesn't have a fruit logo on it" perhaps. Never had issues with those.

[ManeBjorn]

Thanks for the update.  I am waiting excitedly for the USB adapters.
Remember to ping me when they get here.
