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
Upgraded quad-chip with BM1370 chips, doubling hashrate of original NerdQAxe. Powered by 12V DC via XT30 connector, requires 10A PSU.
The NerdQAxe++ is a SHA-256 cryptocurrency miner manufactured by D-Central. It delivers a hashrate of 4 TH/s with a power consumption of 120W, achieving an efficiency of 30 J/TH.
Built on the BM1370 ASIC chip, uses air cooling, operates at 42 dB noise level, weighs 0.5 kg, measures 120x75x45.
With a home mining score of 58/100, this miner is moderately suitable for residential use. It produces 409.4 BTU/h of heat output, making it suitable for supplemental space heating.
At 30 J/TH, the NerdQAxe++ sits in the previous-generation efficiency tier; it runs best where electricity is inexpensive, or as a dual-purpose heat source.
The NerdQAxe++ is solo-mining capable, so you can point it at your own node or a solo pool for a shot at a full block reward, and its waste heat (around 409.4 BTU/h) can be ducted into a room, turning money you would otherwise spend on heating into hashrate.

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 $0.09 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++?
The NerdQAxe++ has a home mining score of 58/100. With 42 dB noise and 120W power draw, it may require a dedicated space like a garage, basement, or outdoor enclosure. Consider noise insulation and proper ventilation.
Can the NerdQAxe++ heat my home?
The NerdQAxe++ outputs approximately 409.4 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.
What power supply does the NerdQAxe++ need?
The NerdQAxe++ draws 120W of power. You need a power supply rated for at least 132W with appropriate voltage (12V DC (XT30 connector)). D-Central stocks compatible power supplies in our shop. Always use a quality PSU from a reputable manufacturer to protect the miner and wiring.
