Mining knowledge, repair guides, and industry insights from the workshop floor.
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.
There is a quiet crisis unfolding across the Bitcoin mining industry, and it spells opportunity for anyone with a soldering iron, a sharp mind, and the nerve to build something real.
The Bitmain APW12 is the power supply unit that brought the entire S19 generation of Bitcoin miners to life. Every Antminer S19, S19 Pro, S19j, S19j Pro, S19a, S19 XP, T19, and their…
The MicroBT Whatsminer M30S is the machine that earned MicroBT its seat at the table alongside Bitmain. Released in early 2020, the M30S delivered 86 TH/s of SHA-256 hashrate at 38 J/TH —…

Every ASIC miner you own is constantly writing a diary. Every second it runs, it records chip initializations, temperature readings, voltage adjustments, pool connections, share…
Your Antminer shipped with Bitmain’s stock firmware — our Antminer firmware update guide covers all firmware options in detail.
Solo mining is a numbers game. Your Bitaxe is hashing against the entire Bitcoin network — roughly 800+ EH/s of combined computational power.
Every watt of electricity that enters an ASIC miner exits as heat. That is not a design flaw — it is thermodynamics. A Bitcoin space heater is simply the honest acknowledgment of this…
This reference manual is your field handbook for diagnosing Antminer issues. Whether you are staring at a blinking red LED at 2 AM or parsing cryptic kernel log messages over SSH, this…
The NerdOctaxe Gamma is the most powerful open-source Bitcoin miner ever built for the desktop. Eight BM1370 ASIC chips — the same silicon inside Bitmain’s flagship Antminer S21 Pro —…
The NerdMiner is your $50 entry ticket into the world of Bitcoin mining. Built on the ESP32-S3 microcontroller (TTGO T-Display S3 board), it is a tiny, silent, USB-powered device that…
The NerdQAxe++ is a quad-chip open-source Bitcoin solo miner built around four BM1370 ASIC chips — the same silicon powering Bitmain’s flagship Antminer S21 Pro.
The NerdAxe is where open-source Bitcoin mining gets real. Built around the BM1366 ASIC chip — the same 5nm silicon that powers Bitmain’s industrial-grade Antminer S19 XP — the NerdAxe…
The Bitaxe GT (Gamma Turbo), model designation Bitaxe 801, is the most powerful single-board Bitaxe ever built. It pairs two BM1370 ASIC chips — the same silicon that drives Bitmain’s…
The Bitaxe Hex is the flagship multi-chip open-source Bitcoin solo miner — and it changes the solo mining equation entirely.
The Bitaxe Gamma is the latest generation of open-source solo Bitcoin miners, built around the BM1370 ASIC chip — the same silicon powering Bitmain’s flagship Antminer S21 XP.
The Bitaxe Supra is an open-source, standalone Bitcoin solo miner built around the BM1368 ASIC chip — the same chip family used in Bitmain’s industrial-grade Antminer S21 series.
