NerdQAxe+
Open Source Hardware
This miner is built on open-source hardware designs — transparent schematics published for anyone to audit, modify, and manufacture. No vendor lock-in, no proprietary firmware, and community-verified security.
Every Bitcoiner who cares about decentralization should own open-source mining hardware. It is the ultimate expression of hardware sovereignty — no single company controls the design, the firmware, or your ability to mine.
Explore the Bitaxe Hub →Open Source Miners United
Open Source Miners United (OSMU) is the community movement behind open-source Bitcoin mining hardware. The designs were published openly, enabling permissionless manufacturing worldwide — ensuring no single entity controls mining hardware production.
D-Central participates in the OSMU ecosystem by assembling open-source miners, carrying Bitaxe-compatible accessories, and supporting builders from Canada.

Heating offset estimates the value of heat replacing an electric space heater during heating season (~6 months/year in Canada). Actual savings depend on your heating setup and climate.
Solo Mining Estimate
Solo mining is a lottery. There is no guarantee of finding a block. These estimates are based on current network difficulty and your hashrate. Every hash has an equal chance.

Home Mining Assessment
Quad-chip open-source miner with BM1368 chips and a color LCD. Near-silent in quiet mode and efficient enough for 24/7 home operation. Powered by 12V DC via barrel jack; a 12V/10A adapter is recommended.
The NerdQAxe+ is a SHA-256 Bitcoin solo miner built on the open-source NerdQAxe design from the OSMU (Open Source Miners United) community. It delivers a hashrate of 2.4 TH/s with a power consumption of 55W, achieving an efficiency of approximately 23 J/TH.
Built on four BM1368 ASIC chips — the same generation of silicon found in the Antminer S21 — it uses air cooling, runs near-silent (around 25 dB in quiet mode), and is powered by 12V DC. The BM1368 chip distinguishes the NerdQAxe+ from the original NerdQAxe (BM1366) and the higher-tier NerdQAxe++ (BM1370).
This quad-chip miner produces roughly 188 BTU/h of heat output, making it suitable for supplemental space heating in a home office or small room.
The NerdQAxe+ is solo-mining capable, so you can point it at your own node or a solo pool such as solo.ckpool.org or public-pool.io for a shot at a full block reward, and its waste heat can be ducted into a room.
D-Central stands on the shoulders of the open-source mining community: the NerdQAxe hardware and AxeOS firmware are the work of contributors like shufps and the broader OSMU initiative. Every design file and line of firmware is publicly available. Full source: github.com/shufps/qaxe

Frequently Asked Questions
What are the current mining economics for the NerdQAxe+?
At $0.07/kWh, the NerdQAxe+ currently shows an estimated daily net cost of $0.03 before pool fees and hardware cost. Lower electricity rates, network changes, BTC price changes, or useful heat recovery can change the result.
Can I mine Bitcoin at home with the NerdQAxe+?
Yes, the NerdQAxe+ scores 74/100 for home mining viability. It produces 25 dB of noise and draws 55W. It is suitable for home environments with appropriate placement considerations.
Can the NerdQAxe+ heat my home?
The NerdQAxe+ outputs approximately 188 BTU/hr of heat. For reference, a typical space heater produces 5,000-5,500 BTU/hr. All electrical energy consumed by the miner is converted to heat, making it 100% efficient as a heater. D-Central offers Bitcoin Space Heater builds designed specifically for home heating integration.
Does D-Central repair the NerdQAxe+?
Yes, D-Central provides professional repair services for the NerdQAxe+. Services include hashboard repair, control board diagnostics, fan replacement, and full refurbishment. Ship your miner to our Laval, Quebec facility for diagnosis and repair.
What power supply does the NerdQAxe+ need?
The NerdQAxe+ draws 55W of power. You need a power supply rated for at least 61W with appropriate voltage (12V DC (barrel jack)). D-Central stocks compatible power supplies in our shop. Always use a quality PSU from a reputable manufacturer to protect the miner and wiring.
