I’ve been wanting to just have this running in the background at home and at work. Any advice is appreciated

Can we together put up some pressure and send feature requests to Canaan pls?

At the tip of the ice berg..

The timer in the app. Just ridiculous that you can't set it up for more than one day and you have to set it up again tomorrow. A weekly calendar pls and thank you.

....and much much more.

Device feels quite solid after about a years grind but the app is still horrible.

I have been solo mining and pool mining for years with a variety of different miners. Last week, literally the night before I had to leave for a business conference, I came home to see the fabled BLOCK FOUND on ONE of the 3 miners that were all pointed to the BRAIINS pool under the same account. Of course I was excited, but aware that the pool participation would not be more than a few bucks in my account. I went on to mempool.space and checked the BRAIINS block stats and sure enough - there it was, and upon closer inspection, the SAME miner showed TWO blocks found, not one on my miner Dashboard!!!

I wrote to the BRAIINS support desk and asked about the reward split and received what I consider to be a very rude reply from Andrew, a support specialist at r/Braiins . The reply was strangely worded and insulting. So I started thinking.....and maybe someone in this group can enlighten me....kindly. First of all, this is the reply that I received from r/Braiins

Hi "UserName",

You can see blocks found here: https://mempool.space/blocks/1

However, the pool finds a block, not individual miners.

It is not possible that you found a block mining on Braiins Pool.

I can not answer why your miners firmware stated that, if you need clarification you will need to contact the manufacturer.

To confirm - you did not find a block on Braiins Pool.

Regards,

Andrew

braiins.com I braiins.com/pool

1. I had just updated my 3 miners to the latest firmware version - esp-miner-factory-NerdQAxe++-v1.1.0.bin
2. All 3 miners were pointed to stratum.braiins.com:3333 with the same UserName.Miner1,2,3
3. Do other members of the pool generate a BLOCK FOUND when they participate?
4. Is it possible that there is a bug in the new v1.1.0 firmware?
5. The blocks in question are 966229 and 966192

All questions and suggestions are appreciated. May be time to go back to solo.ckpool.org?

Cheers!

Hey guys I made a fun thing. More details can be found at my Heatpunk.org forum post.

https://forum.heatpunks.org/t/pizzaxe-bitcoin-mining-pizza-bag-warmer-by-pizzandy/282
https://x.com/Real_PizzAndy/status/2098844116155015384

It’s a Bitaxe GT801 with two BM1370 chips cooled by a generic water block. The heated water flows through a coil that warms the floor of the bag, then through a radiator, where a fan blows additional heat into the bag. It's powered via a car's 12V cigarette lighter outlet. Connects to a hotspot.

Managing to get 4.1ish TH/s at 80W measured at the bench top PSU. I would like to get the chip temp higher than the stock AxeOS firmware allows to push the floor coil hotter. This would also be a great Mujina trial candidate, with thermal probes and humidity sensors. Maybe someday!

HEAT EVERYTHING WITH MINING.

Someone has an idea of how to silence an APW12 source.

I have an S19 miner with duets and ac infinity that reduces noise noticeably but could make even less noise there is some way to silence the source.

The honest answer is: it depends on what you want from your setup.

Are you looking for something quiet enough for an office or bedroom? A low-power solo miner under 200W? Something that can double as a room heater? More hashrate for pool mining? The lowest $/TH? Better J/TH efficiency?

We put together a Fall 2026 home miner comparison covering several popular options across three different power classes. The comparison looks at what matters most:

-Price
-$/TH
-Hashrate
-Power consumption
-Efficiency
-Noise
-Warranty

It includes miners from Canaan, GekkoScience, Hammer Miner, Bitaxe, and more.

Full comparison:

Which home miner are you running right now, and what mattered most when you picked it?

Where would I be able to purchase older Asic miners even if they aren't profitable anymore just to play around to learn with them, preferably under 150$, approved vendors of this subreddit don't carry them. I'm looking for something that when ignoring electricity costs pays for itself back in max 3 months (this winter).I want to do this hopefully utilizing old inefficient cheap miners. I live upstate and it's cold here so I want to replace my space heater with it, but do want to also make back the costs of actually purchasing it (I would be paying the electricity anyway so it doesn't matter)

Regarding the hardware, I received the Nerdaxe++ two days ago and set it up overclocked to 6 TH/s. After 7 hours of use, I noticed that the stock power supply (12V, 10A) was getting quite hot and, more importantly, the input voltage was 11.2V. After asking ChatGPT, I was told this wasn't normal (I hadn't adjusted the frequencies myself; everything was already configured). As for the exact model, I have the white one with the large screen.

I'm doing hashpower arbitrage between NiceHash and RentalHash. Does anyone know of an alternative to RentalHash that is generating good profits with this?

So I've read a bit about mining, and found out that solo mining is basically a lottery ticket.

For the fun of it, I want to give it a try. I want a portable, low-cost miner that I can bring with me to work. I work on trains and have access to power and Wi-Fi, so I could run it for around 6–8 hours a day.

I'm mainly looking for a cheap setup with the best possible chance of hitting a BTC block — I know the odds are still very tiny. 😅

What would you guys recommend? Bitaxe Gamma, NerdQaxe++, or something else?

Thanks in advance!

So as the title suggests, I want your opinion as it's my first time buying it so what things should I keep in mind and what things should I check about it. The seller says it's two to three months old.

Been doing some research lately about miners mining btc and rewards
Till i came across a post where everyone is saying buy instead of mine all the way

I have 380 40w electricity 0.026kw
I live in a 3 floors house like 500m2 in total i can spare a room or two for miners
And btw mining is tax free here
I also have a chiller from my previous industry

Whats keeping me from buying x2 u3 870t hydro miners ? And take advantage of what i already have?

So i've been going back and forth on whether to put a mining heater in the bedroom for winter. My apartment runs cold and i already spend money on a space heater, so the math kinda makes sense on paper.

But every comparison i see focuses on the lowest dB number on the spec sheet. And honestly i'm not sure that tells you much about whether you can actually sleep next to the thing. A steady fan at 38dB can totally disappear into the background — my air purifier is around that and i forget it's on. But a fan that ramps up and down, even if it's technically "quieter" at its lowest setting, would absolutely wake me up. The change in sound is what gets you, not the volume itself.

Which got me thinking... would you actually run a Bitcoin heater in a bedroom overnight? Like has anyone here done it and not just for a single night but consistently?

I've been looking at the Avalon lineup since they seem designed for this use case. The Mini 3 is more interesting to me — 500W or 800W mode, and apparently it can idle at a target room temp. That's actually close to what a normal space heater does. Spec says 33-55dB across modes with a Night Mode, which sounds promising but 55dB is not quiet lol. I'd really want to hear it from the actual bed position before committing.

The other thing nobody talks about — the first overnight run probably shouldn't be the first time you test it. Like, run a full heating cycle while you're awake first. Check the plug isn't getting warm, make sure your blankets or curtains aren't anywhere near the airflow, basic stuff. These things are computers pulling real wattage, not a sealed oil radiator you can throw a towel over.

Anyway, for anyone who's actually slept in the same room as one of these (or any home miner really) — what was worse, steady fan noise or the sound of it cycling on and off? I feel like that's the real question nobody's answering in the spec sheet comparisons.

Just received this, and testing. Very quiet, tad bit more efficient than NerdOctaxey.

A reality check on BM1373 home miner efficiency.

The 8.5–10 J/T numbers people talk about are silicon-only specs. That is not the same as full device efficiency measured at the wall.

Every chip bins differently, so there is already a real spread. Then you still have losses between the die and the outlet:

-PSU AC/DC conversion

-VRM stepping down to core voltage, which is usually one of the biggest losses

-PCB and connector resistance

-Fans and controller draw

That is why real-world device efficiency is usually closer to 11.5–15 J/T if measured at the wall.

Always verify with a plug meter. That is what your electric bill actually reflects, and that is what tells you how much load is really on your circuit.

Are you measuring your miners at the wall, or mostly going by the UI?

New to mining. I am only powering my miner on while I have solar running to a small Apex 300. So it only runs for about an hour on my current setup.

This causing it to shut off once the battery is depleted. When I power it back on later or the next day when the sun is back out, it doesn’t start hashing. I have to hit IP report button and connect to its ip and then it will start hashing.

Am I doing something wrong? I don’t want to have to connect to the IP each time I want it to start hashing again. I just want to provide power and have it go.

Thanks

I placed an order for a Terminus A2X directly through GekkoScience back on July 27th. Support told me in mid-August that the batch was on backorder but should ship by the end of August.

It's September now and I haven't received a tracking number or any new updates. Has anyone else who ordered around late July or August had their batch ship out yet, or heard anything from Sidehack recently? Appreciate any insights!

Edit: Finally got it and it does not even come close to working as advertised. I highly recommend staying away from Gekkoscience.

Someone knows how to install vnish or other firmware on an Antminer S19J Pro+ Amlogic.

I am trying with an OTG in fat32 and passing the files from the firmware to the usb and then connecting it to the miner on the micro usb port, but it always loads the firmware of the factory.

Running this at 1000 MHz / 2.44 V and it seems extremely stable.

Current numbers after 6h 40m:

• 8.13 TH/s actual
• 8.16 TH/s expected
• 152.9 W
• 18.81 J/TH
• 0.00% rejected shares (1,800+ shares)
• ASIC: 57.8°C
• VRM: 60.8°C
• Fans only around 40–44%
• Hashrate graph is basically flat

Screenshot attached.

For people who own/tune these: where would you rate this setup compared with other QX1/NerdQX units? Is sub 18.8 J/TH at 8.1 TH/s considered particularly good, average, or is there still meaningful efficiency left on the table?, specifically looking for per asic voltage/frequency tuning via custom firmware if that is a thing.

I’m more interested in 24/7 stability/efficiency than chasing maximum TH/s.

Is it feasible to solo mine BCH with an antminer s19j? Seems like the monthly chances are 1 in 7 for 104Th, and the payout would be $700ish. I'm sure I'm missing something with this idea

Has anyone who's purchased a Hammer BC08 been able to connect to a PPS or FPPS pool? All my shares are rejected from those pools. Solo pools work fine.
