If you have spent any time searching for Bitcoin mining hardware, you already know the landscape is a mess. Drop-shippers selling rebadged machines they have never opened. Marketplaces full of “miners” that are really just space heaters with a logo slapped on. Spec sheets copied and pasted with no idea what the numbers mean. D-Central Technologies has been doing this since 2016 — building, repairing, and shipping real mining hardware out of Laval, Quebec — and this page is the honest map of everything we offer and how to figure out what you actually need.
We are Mining Hackers. That is not a marketing line. It means we take institutional-grade mining technology — the same chips and boards that run in warehouse-scale farms — and hack them into something a person can run in a spare room, a garage, or on a desk. Every miner running in a home instead of a corporate data center pushes hashrate back toward the edges of the network, where it belongs. That is the whole point. Decentralization of every layer of Bitcoin mining, one pleb at a time.
What D-Central Actually Sells
Our catalog is built around one principle: hardware a home miner can realistically own, power, and live with. We do not stock 13,000-watt immersion rigs you would need an industrial service panel to run. We stock the machines that work in the real world — from a 15-watt solo miner on your bookshelf to a heavily modified Antminer that warms your living room through a Canadian winter. Here is the breakdown.
Open-Source Miners (Including Bitaxe)
The Bitaxe is the world’s first open-source ASIC Bitcoin miner — a single-board solo miner running real SHA-256 hashing power on fully open hardware. It is not a space heater and it is not a toy. It is a roughly 15-watt machine that solo mines straight out of the box, and D-Central has backed it since day one. We carry the current board generations — the lineage runs Max, then Ultra, then Supra, then Gamma — with the Bitaxe Supra (625–775 GH/s on the BM1368 chip) and the Bitaxe Gamma (1.0–1.2 TH/s on the BM1370 chip) as the models we ship fully assembled, running AxeOS, powered over 5V, and ready to mine in minutes.
A Bitaxe will not pay your mortgage. What it does is give you a real, independent shot at a full block reward every ten minutes for the price of a nice dinner and the power cost of a phone charger. It is the purest expression of solo mining: your machine, your node, your block. We are pioneers in this ecosystem — D-Central built the original Bitaxe Mesh Stand and developed a string of heatsinks, cases, and accessories that the broader community now relies on. Because the hardware is open source, anyone can manufacture it. We compete on expertise, build quality, and the fact that we have been here since the beginning.
Beyond Bitaxe, we stock the wider open-source lineup — NerdAxe, NerdQAxe, Nerdminer, PiAxe, and more arriving regularly. Browse the full range in Open-Source Miners and Bitaxe, and pair your board with heatsinks, stands, sockets, and PSUs from Bitaxe Accessories. If you want to go deeper on any single model — setup, overclocking, troubleshooting, comparisons — that all lives in the Bitaxe Hub.
ASIC Miners Built for Home Use
When a Bitaxe is not enough hashrate and you want a full ASIC without the jet-engine noise and 240V demands of a stock unit, this is where D-Central’s hacker engineering shows. We do not just resell Antminers — we rebuild them for the conditions a home miner actually has.
- Antminer Slim Edition — Our answer to a simple problem: where do you put a Bitcoin miner when you live in a 600-square-foot apartment? A single-hashboard build in a custom PETG shell with quiet fans, tuned for standard North American 110V power. It is the most approachable way to run a real ASIC at home, and it currently ships in a price range around 560–745 CAD depending on configuration. Five dollars from every sale supports Open Source Miners United.
- Antminer Loki Edition — For miners who want more hashrate than the Slim and are willing to manage a bit more power and noise. The Loki builds use 110V power modifications to unlock Antminer S19-class boards for home electrical service while keeping the footprint and sound under control.
- Refurbished and standard ASICs — We also carry tested, refurbished full ASICs for miners who have the electrical setup and the space. Every unit that leaves our shop has been through our bench.
The full selection lives in ASIC Miners. If you are weighing a Slim against a Loki against a stack of Bitaxes, the Mining Profitability Calculator will tell you what each one actually returns at your power rate before you spend a dollar.
Bitcoin Space Heaters
Here is a piece of physics most miners miss: every watt a Bitcoin miner consumes converts to heat. One hundred percent of it. That is not a flaw — it is an opportunity. D-Central pioneered the Bitcoin space heater concept in Canada, taking proven ASIC hardware like the Antminer S9 and rebuilding it specifically to heat a room while it mines. Instead of burning electricity through a dumb resistive heating element that gives you nothing back, you push that same electricity through a mining chip and get warmth and Bitcoin.
Our space heater editions — built on the S9, L3, S17, and S19 platforms — run on silent Noctua or Arctic fans and are designed to live in a home, not a warehouse. The Antminer S9 Space Heater Edition is the entry point: plug-and-play, whisper-quiet, and genuinely useful through a Canadian winter. Explore the full range on the Bitcoin Space Heaters page or in the Space Heaters shop category. Note the distinction clearly: a space heater is a full ASIC repurposed for heat output. A Bitaxe is a 15-watt open-source solo miner. They are different tools for different jobs — do not confuse the two.
ASIC Repair
That miner sitting dead on your shelf is not garbage. It is a machine built to hash, and with the right hands on it, it will hash again. D-Central is Canada’s number one ASIC repair service — over 2,500 miners brought back from the dead since 2016 with a 95%+ success rate. We do chip-level diagnostics and board-level repair on everything from beat-up S9s to the latest S21 XPs, organized by manufacturer across Bitmain, MicroBT, Innosilicon, Canaan, and Halong. This is the part of our business no drop-shipper can touch, and it is backed by 38+ model-specific repair guides. If you own mining hardware long enough, something will eventually fail. When it does, send it to ASIC Repair instead of the landfill.
Parts, Accessories, and Power
A mining operation is more than the miner. We stock replacement hashboards, control boards, and ASIC chips for repairs and upgrades; power supplies sized for both full ASICs and low-voltage open-source boards; cooling shrouds, duct adapters, and quiet fans; cables and voltage adapters; and our own 3D-printed accessories — stands, mounts, and components like the “Side Hodler” PSU holder that came straight out of our workshop. Browse Parts, Accessories, and Cables & Power to round out a build. If you are buying a complete first setup, these are the pieces people forget until their miner is sitting on the floor with nowhere to plug in.
Who Home Mining Is Actually For
Let us be honest about expectations, because the rest of the industry will not be. Home mining is not a money-printing machine. At today’s network difficulty, a single home miner is not out-earning a warehouse. What home mining is: a way to participate directly in securing Bitcoin, a hedge that earns sats instead of sitting idle, a genuine shot at a full block reward if you solo mine, and — done right — a way to turn electricity you were going to spend anyway into something useful. Different people come to it for different reasons:
- First-time miners who want to learn how Bitcoin mining actually works without risking a five-figure hardware budget. A Bitaxe is the cleanest on-ramp in existence.
- Solo miners and lottery miners chasing a full block — passionate Bitcoiners who would rather roll the dice on their own machine than collect steady pool payouts.
- Energy optimizers with solar, cheap overnight power, or a heating bill they would like to do something productive with. Dual-purpose mining turns a cost center into a mining rig.
- The DIY and maker crowd who want to build, mod, overclock, and tinker. Open-source hardware is a playground, and we stock the parts.
- Experienced operators expanding a home setup, replacing failed hardware, or sourcing repairs and parts they cannot get anywhere reputable.
- Decentralization-minded Bitcoiners who understand that hashrate concentrated in a few corporate pools is a problem, and that running a miner at home is part of the fix.
How to Choose the Right Mining Hardware
There is no single “best” miner — there is the best miner for your situation. Four factors decide it: your budget, your goal, your electrical setup, and how much noise you can tolerate. Work through them in that order.
1. Budget and Goal
If you have a modest budget and your goal is to learn, solo mine, or chase a block, start with a Bitaxe. It is low cost, low power, and low risk. If your goal is meaningful, steady hashrate and you have a few hundred dollars to a low four figures to spend, look at the Antminer Slim Edition or Loki Edition. If your real goal is heating a space and mining is the bonus, a Bitcoin space heater is the honest choice — you were going to pay to heat the room anyway.
2. Electrical Setup
This is where most home mining plans fall apart. A Bitaxe runs off a 5V USB-style supply — any outlet, anywhere, no thought required. Our Slim and Loki editions are specifically built for standard North American 110V household power, which is the whole reason they exist. Stock, unmodified full ASICs often expect 220–240V service and will trip breakers or simply not run on a normal outlet. Know what your room can deliver before you buy, not after.
3. Noise Tolerance
A stock Antminer is genuinely loud — leaf-blower loud. That is fine in a warehouse and miserable in a home. Everything D-Central builds for residential use is tuned for quiet operation: low-noise or Noctua-class fans, dampened shells, optimized airflow. A Bitaxe is near silent. The Slim and Loki editions are built to live in the same room as you. If the miner is going anywhere near a bedroom or living space, do not skip this factor.
4. Run the Numbers Before You Buy
Once you have a shortlist, do not guess at profitability — calculate it. Your power rate is the single biggest variable in whether a miner earns or bleeds. Plug your hardware and your electricity cost into the Mining Profitability Calculator and you will see exactly where you stand. Still not sure which path is yours? The Start Here guide walks you through a four-question product finder that matches you to the right hardware for your budget, goals, electrical setup, and noise tolerance.
More Than Hardware: The D-Central Advantage
Buying a miner is the start, not the finish. What sets D-Central apart from the drop-shippers and the faceless marketplaces is everything that comes around the hardware. We have been a Canadian company since 2016, with a physical workshop and a team of technicians — not a logo on someone else’s warehouse. We run the country’s leading ASIC repair operation, so the hardware you buy from us is hardware we can keep alive. We publish real guides — setup walkthroughs, overclocking advice, troubleshooting, teardowns — instead of recycled spec sheets. We run our own open-source firmware project, DCENT OS, alongside the broader firmware ecosystem. And we are part of the community, not selling to it from a distance: D-Central pioneered the Bitcoin space heater in Canada and built the original Bitaxe Mesh Stand.
If you are weighing where to spend your money, that lifecycle matters. A miner from a drop-shipper is a gamble with no recourse. A miner from D-Central comes with the people who can repair it, the guides to run it, and a company that has been here for nearly a decade and intends to stay.
Where to Go From Here
You now have the full map. The next step depends on where you are:
- Brand new to mining? Start with the Start Here guide and let the product finder point you to your first machine.
