Why buy from Open Source Miners?
We don't sell anything we don't run ourselves: our own fleet mines around the clock on the exact hardware in this shop.
Open firmware instead of a black box
Bitaxe, Nerdaxe and NerdQaxe are open-source Bitcoin miners: the Bitaxe runs AxeOS, the Nerdaxe family runs NerdOS, a fork of it. Every setting is visible, and clock and voltage are yours to set. Flash firmware updates in minutes with our free web flasher, right in the browser and without extra software.
In stock in the EU, shipped within 24 hours
Every miner marked as available is in stock and ships within 24 hours with tracking, with no customs fees and no import-VAT surprises. Shop availability is always up to date; if something sells out, the restock alert notifies you first.
Support from miners, for miners
We run Bitaxe and NerdQaxe miners around the clock ourselves. Questions about solo mining, pool setup, WiFi or cooling are answered by someone who has the same device on their own desk. In English or German.
Bitcoin only, and you can pay with it
Our miners only compute SHA-256 for Bitcoin. We carry no altcoin miners and make no "cloud mining" promises. Pay by Lightning or on-chain, by card or PayPal, as a guest without an account.

Open Source Miners: Bitcoin mining hardware with premium shipping
Open Source Miners sells open-source Bitcoin mining hardware for the home, from the single-chip Bitaxe Gamma 601 at around 15 to 18 W to the NerdQaxe ++ and the NerdOctaxe with 12 TH/s. Bitaxe runs AxeOS; NerdQaxe, NerdOctaxe and Nerdaxe run NerdOS, an open fork of it. You do not need a manufacturer account or a cloud login, and the source code is public. For each device we list board files, firmware and licence on a page of its own: what is open on our miners. Our miner comparison puts hashrate, power draw and price side by side.
Why open mining hardware?
You set pool, frequency and voltage yourself and watch hashrate and temperature in the web interface of the device. That suits solo mining: the miner works for your own Bitcoin address, and if it ever finds a block, the reward goes to that address. Our guides cover setup, choosing a pool and what matters for mining at home. Want to try it before a device arrives? Rent a Bitcoin miner and the hashrate works on pool.opensourceminers.de for your address. Common questions are answered in the FAQ; for anything else use the contact page.
