Mining knowledge, repair guides, and industry insights from the workshop floor.
So your ASIC miner is down. Maybe a hashboard stopped hashing, a fan died, or the whole unit refuses to boot. You have done the troubleshooting, tried the firmware flash, reseated every…
The Antminer S21 represents Bitmain’s latest generation of SHA-256 mining hardware, delivering up to 200 TH/s at a remarkable 17.5 J/TH efficiency.
Complete guide to ASIC miner repair costs in 2026. Covers pricing for hashboard repair, control board repair, chip-level micro-soldering, PSU repair, and full system rebuilds. Includes repair vs replace decision framework and cost breakdown by miner model.
Yes. Both devices convert 100% of consumed electricity into heat — this is dictated by the first law of thermodynamics.
AxeOS is the open-source firmware that powers every Bitaxe device. It is the brain of your solo miner — the software running on the ESP32-S3 microcontroller that controls the ASIC chip…
Noise is the number one reason people abandon Bitcoin mining at home. A stock Antminer S19 screams at 75 dB — louder than a vacuum cleaner running nonstop in your living room.
If you are buying a Bitcoin ASIC miner in 2026, your decision almost certainly comes down to two brands: Bitmain’s Antminer series and MicroBT’s Whatsminer series.
Choosing the right firmware for your Antminer is one of the highest-impact decisions you can make as a miner. Stock firmware from Bitmain gets the job done, but it leaves serious…
You have decided to mine Bitcoin. Maybe you want to contribute to network decentralization. Maybe you want to heat your home with a miner.
“Should I mine Bitcoin or just buy it?” If you spend any time in Bitcoin communities, you will hear this question weekly. The honest answer is: it depends on what you are optimizing for.
The Bitaxe is the world’s first fully open-source Bitcoin ASIC miner — and it has already changed the game. Born from the cypherpunk conviction that Bitcoin mining should not be locked…

Every electric space heater on the market does exactly one thing: it converts electricity into heat. A 1,500W ceramic heater pulls 1,500 watts from your outlet and produces 1,500 watts of heat.
You are heating your home anyway. Every Canadian winter, every Quebec hydro bill, every baseboard heater running at full tilt is electricity converted to heat with zero other output.
Your ASIC miner is a computer. It runs Linux, connects to the internet, has an SSH server, and often ships with default credentials.
The Bitmain APW9 and APW9+ are the power supply units that powered the entire S17/T17 generation of Bitcoin miners — arguably the most temperamental and repair-intensive generation…
Your roof is producing electricity. Your utility is buying it back at a fraction of its value. Meanwhile, somewhere on the Bitcoin network, a miner is converting that same electricity into…
The NerdNOS is the stripped-down, no-nonsense member of the open-source Bitcoin mining family. Running NerdMiner firmware on an ESP32-S3 microcontroller, it does exactly one thing: it mines Bitcoin.
The Bitaxe Ultra is an open-source, standalone Bitcoin solo miner built around the BM1366 ASIC chip — the same silicon that powers Bitmain’s industrial-grade Antminer S19 XP.
There is a moment every ASIC miner operator dreads. You power on your machine and nothing responds. No web interface. No hashrate.
This is the question that keeps home miners up at night. You are running an S19-series miner — maybe an S19 Pro you bought in 2021, maybe an S19j Pro you picked up used last year, maybe…
You bought an ASIC miner to stack sats. You plugged it in. And now your family is staging an intervention because your basement sounds like a leaf blower factory running overtime.
Here is the uncomfortable truth that most mining hardware sellers will not tell you: the vast majority of ASIC miners on the market cannot run on a standard North American outlet.
Stock Bitmain firmware treats your ASIC miner like a sealed appliance — see our Antminer firmware update guide for a general firmware overview. Fixed frequencies. Fixed voltages.
Your Antminer shipped with Bitmain’s stock firmware. It runs at a fixed frequency, pulls a fixed wattage, and requires a 240V circuit that most North American homes do not have.
This is the definitive Whatsminer error code reference. Whether you are staring at a blinking status LED on your M30S at 3 AM or trying to decode a five-digit error code in WhatsMinerTool…
A Bitcoin space heater is not a desk lamp. It is a serious electrical appliance that draws between 800W and 3,250W of continuous power — 24 hours a day, 7 days a week, for months on end…
Your ASIC miner stopped hashing. The pool dashboard shows zero. The web interface is throwing errors — or worse, the miner will not even power on. Your stomach drops.
Every ASIC miner ships with the same cooling strategy: move massive volumes of air across heatsinks using fans that sound like a jet turbine at close range. It works.
Yes. You absolutely can mine Bitcoin in an apartment. People do it every day — from studio apartments in Toronto to two-bedroom units in Montreal.
