Bucketeer — Bitcoin Mining Firmware

What is Bucketeer?

Bucketeer is firmware for Bitcoin mining devices. It replaces stock firmware with a modern web-based interface, SmartTune automatic frequency/voltage optimization, multi-pool timesharing, and detailed hardware diagnostics. New profiles will be released as we get hold of miners.

Features

SmartTune

Automatic per-chip frequency/voltage optimization. Learns your ASIC's sweet spot over time — finds the best hashrate at the lowest power.

Pool Timesharing

Split mining time across up to 4 pools with configurable allocation percentages. Never miss a block on your solo pool while stacking sats on a PPS pool.

Hardware Profiles

JSON-based board detection — new boards just need a profile file, no code changes.

Web Dashboard

Real-time hashrate & temperature charts, pool config, SmartTune controls, firmware OTA updates — all from a single-page web UI.

Thermal Safety

Layered protection: fan ramps to 100% at 66°C, thermal backoff at 67°C, emergency power cut at 70°C sustained for 10 seconds.

OTA Updates

Update firmware from the web UI — upload a .bin file or check for new releases from miner.bucketmining.com. Web UI partition also updatable.

Supported Profiles

BitAxe Gamma 601

Latest Releases

Beta releases collect anonymous diagnostic data (hashrate, temperatures, board profile) to help improve the firmware. No personal data, pool credentials, or wallet addresses are ever collected.
