Re: BITMAIN AntRouter R1: 1st wireless networking device with bitcoin mining chip
They probably did, yeah. Is that guy passively cooled? If so, they couldn't afford too many watts before the chip would start into thermal runaway and burn up.
Yeah. The sides of these things are actually aluminum (I always thought they were plastic) and the side has a heatsink protruding directly onto the chip (with some paste in-between of course).
I’ve been away from these parts for a few years. Cool to see the evolution of the Pac products. I miss my little sticks.
Re: BITMAIN AntRouter R1: 1st wireless networking device with bitcoin mining chip
Can anyone tell me which Bitmain chip is in this R1-BTC unit? I’ve been digging for hours and can’t find it!
UPDATE: I had a non-functional unit so decided to pull it open. This unit uses the BM 1384 chip, same as the GekkoScience 2Pac miners.
I'm curious, then, why the R1 was only rated at around 5.5 GH/s - did they underclock them to keep heat down?
Re: Official FutureBit Apollo LTC Image and Support thread
I cannot get the Apollo to connect to NiceHash to save my life. No matter what I try, which region or with or without the stratum language... it just wont connect. Can literally connect to any other pool with no issues. Am I crazy?
Re: Official FutureBit Apollo LTC Image and Support thread
Multipools cause issues based on how they send work data. For nicehash try putting #xnsub at the end of the url, and make sure ALL failover and donation pools are disabled.
Thanks for the suggestion. Didn't do the trick. When miner fires back up, I can't even get to dashboard... I've moved it back to the other pool for now. Its not a big deal if I can't get it to work with Nicehash, though I'd like to.
I scrolled back a bit and saw some of the previous negative commentary.
FWIW, I've been a big fan for years. Had several Moonlanders over time, and really love this Apollo LCT unit now. I missed the BTC offering, or I would have gladly jumped on that. I'd been wanting to see someone do something like that for years now.
Keep up the good work.
Re: Official FutureBit Apollo LTC Image and Support thread
Apologies 100% if this has been asked and answered... I did dig around through quite a few of these pages before posting.
Is there an issue with these units and Nicehash? I've tried unsuccessfully all day today to switch the pool to Nicehash, and it immediately goes to an inactive status. I can put it on any other pool and it immediately begins hashing (Sigmapool, Litecoinpool, etc.) with no issues.

Thanks in advance...

...that ran around 2TH over USB from around 145W (12V PCIe), would anyone buy it?
Been wanting this for years.

Question... if the miners were exhausting into a separated "hotbox" or hot zone... and THAT space was being sucked out (basically as you've drawn)... and the "intake" for the miners was the inside air on the "cool" side... assuming the building has some form of insulation, would it not be better to flip your intake inside, so you're shooting the room air into the U vs. the outside air. I'm just wondering if you'd be starting at something slightly cooler than the shaded outside air.
Or maybe the whole building, insulated or not, is a virtual hotbox, so your design makes more sense. Hmm.
We have begun to talk about a 20' shipping container, with a "lean to" of solar panels that go over the container's roof height to provide some building shading.

You do not want a loop system.
If you run air into that u underground it will be cooler air.
just use exhaust fans to,pull air.
I shade the entrance to the hole in the ground.
That air enters at non desert temps.
at least 10 f cooler then the outside air.
the key is the shading tarp and the hole.
note the circle that covers the air hole into the mine that is a filter

Some good points here, and worth looking into. My only reluctance to an evaporative cooler would be that we'd need to have some sort of ongoing water source onsite. I'm not sure if that's an option at some of these sites we're looking at. Literal 40-160 acre flat parcels in the desert. I suppose drilling a well at some point could be a "phase two" option during a later build out.
If the intention is to somewhat cool the room, does the cooled-air system need to match the exact CFM of the miner fans? I more or less thought of it as a way to bring the ambient temperature of the room down a few degrees. I'm sure my lack of an engineering degree is shining right about now... but I more or less thought of this as "injecting" some cooler air into the situation, not necessarily providing ALL of the air that's being exchanged in the room? Or is that dumb?

Yeah, I saw articles on systems like you are describing. It's trading off efficiency for simplicity. It's just a lot more efficient to transfer the heat from a liquid to the surroundings than from air, and liquid holds way more heat per unit volume so you don't have to move it as fast. Keep in mind that you'll need to push around 200cfm of air per miner through your pipe, so you'll need very large pipes and an air system that can handle very big static pressures. So for the scale you're talking about, I think the liquid one with a heat exchanger is probably going to end up simpler in the end. But in my opinion, neither will be as inexpensive or as simple as an evaporative cooling system.
But I'd love to see the results of a test. Just set up a single air loop with a single miner, and bury 50 or 100 feet of 6 or 8" pvc.

I'm kind of reluctant to use the term "geo thermal" because it tends to invoke a more involved system like you're saying with exchangers and such. The system I saw on this TV show was simply air in / air out. Maybe this worked better for this person because of where they were located (they definitely were not out in the middle of the desert)... but it seemed like it would provide a solid temperature year-round, cooler for sure, even if not perfect.
Don't think geothermal works very well with air directly, they normally use liquid and heat exchangers. And you might need 1000s (maybe 10s of 1000s...) of feet of pipe with liquid buried pretty deep in the desert to support the # of miners you can pack into a 900 sq ft shack.
No you're right... I wasn't more clear about that. I'd probably still build a "hot box" for the miners to spout hot air into, and vent that out separately.
So the intake for the geo system would be ambient temp air from the non-hot box part of the room, and then the outflow "geo cooled" air would be directed more closely towards the intake on the miners themselves.
I'm probably not explaining this well, but I definitely wasn't implying running the hot miner air through that.

Am I missing something in the part of forcing hot air in the ground (down) and pulling cold air out (up) with small fans?
Wouldn't it be easier to simply force the air from the outside at ground level though this pipe network and in your shack at floor level and let the hot air simply go up and out with a single fan?

I'm currently entertaining the idea creating an off-grid solar-powered farm in the desert southwest. In the summer when the outside temp are 105 (F) / 40 (C) I'm wondering if a geo cooling option would work.
I recently saw a TV show where the used this to cool an off-grid home that was roughly 2500 sq ft.
From what I gathered, you send some air tubes down 8-12 feet below the ground where the air is a consistent 55 degrees or so. You pull warm air in from one part of the property, shoot it down the tubes, where it naturally cools down, and then back up and into the property at roughly 65-70 degrees.
The electricity draw involved is much lower the air conditioning, obviously, because you more or less are running small fans on the intake/outflow ends of the tube system.
Does anyone think this is do-able for a 700-900 sq foot mining shack out in the desert?

Just wanted to say thanks for this thread... I've been entertaining the idea of launching an off-grid solar mining farm in Southern Nevada or north-western Arizona area for the past few months. There's so much good info here, and I'm thankful for folks like Phillip that have given so freely.
