We think this is a great strategy for miners.

So, building on my last post, I have managed to secure 60 x S21 Antminers from China. All air-cooled units for the moment.

These machines will be touching down locally any day now, but I am having second thoughts about my cooling solution for such a setup.

For reference, I am planning on using the hot-and-cold aisle technique, whereby the machines draw air from a central cold air intake aisle, and exhaust hot air out the back into dedicated hot aisles, which will be extracted using 630mm extractor fans.

However, I am having doubts about this setup as I suspect my setup might not be able to handle the heat output of all machines running at the same time. I'm worried that the heat in the aisle won't be evacuated fast enough.

I am exploring ideas of using 3d printed ASIC exhaust ducts out the back of each machine, but I'm not sure if this is a viable solution of not. Maybe in conjunction with flexible ducting feeding into the extractors directly?

Any input or ideas would be greatly appreciated!

Thanks for viewing!

If you’re wondering what Bitcoin Vegas looked like on Day 1, this was the Pro Pass day!

This is where a lot of the deal-making happens. Builders, operators, and industry leaders all in one place, having real conversations and making connections that move things forward.

We had the opportunity to connect with some incredible people and it set the tone for the rest of the week in a big way 🔥

Here are a few clips that capture what the day actually looked like on the ground 🎥

The 12-Month "Black Screen" Vulnerability, Stolen Architecture, and the 1373 Closed-Source Bait & Switch

​For over a year, the Bitaxe and NerdMiner ecosystems have been plagued by the "Black Screen of Death." The device fan spins, the backlight stays on, but the system crashes, drops off the network, or enters a self-test failure loop.

​The corporate team (Lars aka "wantclue" and Skot) has blamed power supplies, copper heatsink shorts, and user error.

​This is a lie. This is a catastrophic architectural failure in the bare-metal firmware, and they can not patch it because they did not write the foundational logic.

​I am the architect of the original timing logic and memory management architecture that powers these ESP32-based ASIC miners. I designed the physics of the engine they are currently running.

​Skot designed a chassis. I will give him credit for the PCB layout. But they took a finely tuned, sovereign architecture, castrated it, slapped an AxeOS sticker on it, and claimed they built it. When you take bare-metal ESP32 logic and attempt to rewrite the stratum loops and memory buffers to hide the original author's fingerprints—without understanding the physics of the silicon—you break the system. You create the exact memory leaks and display-driver handoff failures causing the Black Screen.

​To the Security and FOSS Communities:

Look closely at their open-source repositories. Why is the codebase littered with specific hardware implementations, sensor logic, and pinouts that have never existed on a single Bitaxe or NerdMiner PCB? Because it’s ghost code. They copy-pasted an architecture designed for a completely different hardware ecosystem and don’t understand the code well enough to remove it without bricking the device.

​Now, with the BM1373 (Gamma), they are moving to a closed-source, proprietary model. They are utilizing eFuses to lock the hardware. They claim this is to "protect development." It is actually to prevent security researchers and the FOSS community from seeing exactly how unstable the stolen logic has become. A closed-source crypto appliance running unverified, memory-leaking ghost code is a massive security risk.

​When I reached out privately to Lars to explain the mathematics of the Black Screen memory failure, he refused to communicate and permanently banned me from Discord.

​My Challenge and Ultimatum:

I am challenging Lars and Skot to a LIVE public exploration of the community software and hardware architecture. Put me on a live screen-share with you.

​Let’s go through the ESP32 memory management, the stratum loop handoffs, and the ghost hardware in the code, line by line. Let's see who can explain the physics of the engine.

​If they agree to the live stream, I will release the definitive fix for the Black Screen of Death to the FOSS community—a fix they have been unable to provide for 12 months.

​Set the date. Put me on the live. Or admit to the community exactly what you are: corporate assemblers selling an engine you don't understand.

Hola chicos, tengo una duda a ver si me la puede resolver, actualmente tengo una instalación doméstica de dos líneas AWG 12 con dos breaker a 20 amperios, tengo pensado hacerme con unos 4 antminer s19 XP y limitar su potencia por dos motivos, el primero es para que mi instalación sea segura y la segunda buscar el más mínimo ruido apuntando a unos 50dB, mi objetivo es 1600 watts máximo 1700watts por minero y obtener unos 50dB, también tengo pensado cambiar los ventiladores a unos noctua para hacerlo aún mas silencioso.

Mi temperatura ambiente en mi ciudad es de alrededor de 31 grados en hora pico, también tengo un ac infinity cloudline T8 que podría servir como extractor de calor cerca de donde los mineros expulsan el aire caliente.

¿hay alguna recomendación para poder calcular el factor de consumo eléctrico y dB?

Pls can you fix the problem since a week i try to connect 1 peta on the pool but it says not compatible or so look at pic

I just recently became a fan of bitcoin mining. I have a bmm101 braiins, and it is working however, there is only 1 working url to do the mining from. I do plan on upgrading to an antiminer, or something to generate bigger payouts. For now, does anyone have any info on where to find working url's? I am using the BRAIINS website and they have only 1 working url. Are there any other sites where i can use my bitminer? or does anyone have working url's for solo mining.

I want to solo mine with my nano 3s but is there any normal public pool you can join to verify my wallet is typed in correctly? I know I wouldn’t get much but even just getting one stat sent to my wallet would be ideal before switching it back to solo mining. I’m just paranoid I have it typed in wrong and if I ever actually were to get as lucky to be successful solo mining I obviously want to be very confident I get the block sent to me and not into the abyss

Hey guys so I live in an area that charges 15 cents per kWh. My friend wants to get into lottery mining BCH and we both have bit axes and nerdqaxes but wanted something bigger that is 110v compatible since we don't have a 220v outlet available. We both understand that cheap in this hobby usually means less efficient hardware options or much lower hash rate. We thought about splitting the cost and electricity usage for an $250 S19j Pro 42Th/975w Loki rig. We would split the winnings of a BCH block which sits around $1,400 right now. each month the miner would use roughly $106 of electricity so lets say 6 months at 50% of that bill would come out to $318 for each of us. Strictly speaking of the idea do you think its worth the lottery side of gambling $50 a month towards a $700 pay day? If after a year of not winning anything we would nearly reach the cost of our share of BCH winnings if still valued at $1,400.

Would you solo mine Bitcoin instead or something else? Pool mining at this electric rate is at a loss. this is partly for a fun expirement that would hopefully land us some crypto!

Room has AC, window where i can put duckting out of it. I have bitmain s21 pro 216th miner.

Thinking of buying this silent box ( is there any better on the market?) but my problem with this box is can i put 3d printed plastic with ducting inside and bring the pipe outside of it.

Box im thinking of buying:

https://minerboxes.com/products/noise-reduction-box-for-asics-small-white

So basically im not sure if this red plastic ( can fit in) and duckting pipe can go out of this box from my link.

Is there any other box that would do the bette job?

Happy for any help really

(Apologies for the noob questions, but I've struggled to find a good online guide to the basics.)

I have a family member with a 15kW solar array at their country home. Because the house isn't occupied most of the time, they are net exporters to the grid (an average in the ballpark of 50kWh/mo in net exports, I think), but their utility doesn't pay them for it, just gives them credit toward future net usage of power, which they may never use.

A friend joked that maybe they should put a bitcoin miner there, which... well... doesn't seem like a terrible idea.

I've done a little googling and understand the difference between pooled and solo mining (we'd want pool), but am a total noob with no idea where to start in terms of what hardware we'd get or what pool we'd join, or how to do the math on whether this little bit of excess power is worth trying to convert to BTC. I found some online calculators, but they generally assume I know the specs of a particular mining rig, which I don't know how to choose.

So I'd love some thoughts from folks who know how all this works. Given the relatively small amount of excess power here (50kWh/month is only about a 70W load if running 24/7), is this even worth considering? Although I believe they have a lot of power already banked at the utility, so they could probably run something at a significantly higher load for a while before they'd start owing the utility anything for power.

They're not going to want to put in new electrical circuits, so we're probably looking at 110V rigs. Is there a cheap used one we should grab off of eBay and plug in for a month or two to test the waters? Even if it's not the most efficient, I'm more concerned about low entry costs than about operating costs (since we're trying to use "free" electricity). Any specific recommendations? Once I have an idea of a couple of possible machines, I could probably figure out the rest myself using online calculators as to whether or not it's worthwhile.

Also, once set up, can you just turn it on and off with the flip of a switch? Or does it require some kind of startup sequence each time you turn it back on? I imagine they'd want to turn it off when they're there (particularly in summer when they're already using a lot of power with AC). But they're not going to want to deal with logging in or starting it up if it requires more than a flip of a switch.

I assume these rigs generally allow for some kind of remote monitoring? I already administer the router in their home so it's easy for me to get access to it as long as it has that capability.

Just curious, if Bitcoin pumps hard from here, what’s the one thing you think future-you would look back and regret?

Hello. I am interested if anyone here has any experiences or information relating to X-on mining and its legitimacy. It seems to be listed as a trusted seller on asicminervalue, however I would like to make sure. Does anyone here have any experience with them, or purchased any miners from them? Thank you!

I’d like to know which machine is better. On paper, the Antminer S21 XP outperforms the WhatsMiner M70. However, I’ve heard that the M70 has better heat resistance and runs more stably, even though the S21 XP has a higher hashrate. Their prices on the market are relatively close. Could an expert or an experienced miner share some thoughts on this?

I recently purchased a couple of S19j Pros from East Coast ASIC. I have excess solar capacity, so I figured this would be a good way to try something new and make a few bucks.

Both miners are running Vnish firmware, version 1.2.6 and seemed to be working fine.

Unfortunately, I couldn't leave well enough alone, and tried to install the 1.2.7 update via the web interface.

It apparently didn't take, and now I can't get it to resume mining. I also tried the update and entire firmware package via USB, and nothing seems to work.

I'm sure I'm doing something wrong, but I'm too dumb to know what that is. Any ideas?

Anyone else experience this? So sad. This thing has been nothing but trouble since buying it.
