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.

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?

Anyone out there ready to make any moves on this coin? Seems like the explorer and such choked again in August.

BUMP

Still looking...

Any Murfcoin folks still around? PM me if you want to unload your holding.

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?

Mac wallet appears to have zero connections... been running for days, never gets anywhere.

Thoughts?

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.

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...

Been wanting this for years.

If anyone in the CopperCoin community wishes to sell some of their copper, I'm willing to buy. Can pay via BTC, LTC or PayPal.

Send me a DM here to work a deal.

Thanks for the visuals... helps me a LOT.

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.

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?

Bump

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.


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.

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 builder 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 ground temperature 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 than 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?

Mac wallet has 0 peer connections. What gives?

Hey gang,

Thanks!

UPDATE: Two years later, but felt like an update to close out this thread was appropriate. The last-mentioned spot in my March 27th post was a two month negotiation to nowhere. The further and further we went down the rabbit hole with the owner of the building, the less and less friendly the deal became. With all the various chatter about Bitcoin and mining, and "crypto thieves" as he called it... he started asking for insane security commitments from us, highly over-exaggerated insurance requirements, and other things. We finally walked away from the conversation in early June of 2018.

From there, we took a break. In August of 2018, we began our search once again with a new commercial real estate broker. Several smaller options presented themselves, but had no room for growth. Every time the word "Bitcoin" or "mining" was mentioned, the conversations soured. Both brokers we used insisted that we be honest about our intentions for the building, which I both agreed with and disagreed with to certain extents.

The long story, short... after another full summer and fall of looking for space that fit our budget and power requirements, my loose compact of guys fell apart. One of our guys went off and started hosting in a tiny office space somewhere (the smallest of our group), tripping breakers every 12 hours and got kicked out that space later. I sold my machine to the middle-sized guy in our group, and he shipped them off to two different hosting spots in Washington and Montana respectively. The very largest of our group eventually leased a small warehouse near Austin, TX where he thrived for about six months. But he was power-locked, and the local utility was a non-starter for any conversations to bring more power to his building. When his lease expired, he off'd his gear on eBay and walked away.

At the end of the day, none of us got the dream together. I took a good six months off crypto entirely and focussed on my day job. I've been running a tiny AltCoin farm from my home, and recently acquired the LuckyAltcoin Pool https://luckyaltcoin.com/ if anyone wants to come grind some smaller coins with us...

Working up some "whats next" ideas now, and getting the Crypto bug again. Hoping to share some ideas soon.
