Nerdminer
Educational lottery miner based on ESP32. Essentially zero chance of finding a block, but a fun way to learn about mining. Completely silent, no fans.
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 is a pioneer manufacturer in the OSMU ecosystem — involved since the very beginning. We created the original Bitaxe Mesh Stand, developed leading heatsinks and accessories, and stock every variant. When you buy from D-Central, you support a company that helped build this movement.

This device is assembled and quality-tested by D-Central Technologies in Canada. As a pioneer manufacturer in the open-source mining ecosystem, D-Central has been building these devices since the very beginning — creating the original Bitaxe Mesh Stand and developing leading accessories like custom heatsinks, cases, and power solutions.
When you buy from D-Central, you get a device built by engineers who understand Bitcoin mining hardware inside and out. Every unit undergoes thorough testing before shipping, and is backed by Canadian-based technical support and the ASIC repair expertise that comes from servicing thousands of miners.
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.

Frequently Asked Questions
Is the Nerdminer profitable?
At $0.07/kWh, the Nerdminer currently operates at a daily loss of $0.00. However, profitability can improve with lower electricity rates or rising BTC prices. If used as a space heater, the heating offset may make it economically viable.
Can I mine Bitcoin at home with the Nerdminer?
The Nerdminer has a home mining score of 35/100. With 0 dB noise and 1W power draw, it may require a dedicated space like a garage, basement, or outdoor enclosure. Consider noise insulation and proper ventilation.
Can the Nerdminer heat my home?
The Nerdminer outputs approximately 3.4 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 Nerdminer need?
The Nerdminer draws 1W of power. You need a power supply rated for at least 1W with appropriate voltage (5V USB-C). D-Central stocks compatible power supplies in our shop. Always use a quality PSU from a reputable manufacturer to protect your investment.
