NerdAxe
Open-source solo miner with built-in display showing hashrate and stats. Ultra-quiet, runs on 5V barrel jack. Great educational device.
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.

This device is assembled and quality-tested by D-Central Technologies in Canada. D-Central builds open-source mining hardware and related accessories, including heatsinks, cases, stands, and power solutions.
When you buy from D-Central, you get a device prepared by a team that works directly with Bitcoin mining hardware. Units are tested before shipping and backed by Canadian technical support and ASIC repair experience.
Supporting manufacturers like D-Central is how open-source hardware achieves real decentralization — multiple independent producers worldwide, each building from the same open designs, ensuring no single entity controls the supply chain. Your purchase directly supports this mission.
Shop D-Central Miners →Built for Solo Mining
Solo mining means mining independently — no pool, no shared rewards. One lucky hash wins the entire block reward. Low-power miners like this one are perfect for solo mining: the electricity cost is negligible, so you can run 24/7 as a perpetual lottery ticket.
Every hash has an equal chance. Every hash counts.

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
Open-source solo miner with built-in display showing hashrate and stats. Ultra-quiet, runs on 5V barrel jack. Great educational device.
The NerdAxe is a SHA-256 cryptocurrency miner manufactured by D-Central. It delivers a hashrate of 500 GH/s with a power consumption of 12W, achieving an efficiency of 24 J/TH.
Built on the BM1366 ASIC chip, uses air cooling, operates at 30 dB noise level, weighs 0.2 kg, measures 80x50x30.
With a home mining score of 70/100, this miner is well-suited for residential use. It produces 40.9 BTU/h of heat output, making it suitable for supplemental space heating.
At 24 J/TH, the NerdAxe sits in the previous-generation efficiency tier; it runs best where electricity is inexpensive, or as a dual-purpose heat source.
The NerdAxe 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 40.9 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 NerdAxe?
At $0.07/kWh, the NerdAxe currently shows an estimated daily net cost of $0.00 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 NerdAxe?
Yes, the NerdAxe scores 70/100 for home mining viability. It produces 30 dB of noise and draws 12W. It is suitable for home environments with appropriate placement considerations.
Can the NerdAxe heat my home?
The NerdAxe outputs approximately 40.9 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 NerdAxe need?
The NerdAxe draws 12W of power. You need a power supply rated for at least 13W with appropriate voltage (5V DC (barrel jack 5.5x2.1mm)). D-Central stocks compatible power supplies in our shop. Always use a quality PSU from a reputable manufacturer to protect the miner and wiring.
