Braiins OS 26.10 reduces unnecessary Antminer restarts, improves chip-temperature fan response and fixes PSU communication issues—without claiming an unverified hashrate boost.
-
OSHRE.005 covers power busbars, signal-ribbon cables, poor contacts, missing-board faults, safe connector diagnosis and real historical ASIC hashboard photographs.
-
OSHRE.004 explains Antminer hashboard temperature sensors, LM75A and I²C fault paths, Bitmain P:1 and J:6 alarms, Braiins T5, cooling issues, safe diagnosis and repair verification.
-
A practical hashboard repair engineering lesson on ASIC discovery, zero-chip and partial-chain errors, compatible test fixtures, safe fault localization and post-repair verification.
-
Bitcoin difficulty rose 5.54% on October 29 to 148.36 trillion, pushing miners’ expected BTC revenue per unit of hashrate lower as hashprice approached $33.
-
Keel postponed an October 28 open house for its proposed 96 MW Sherbrooke AI campus, which would consolidate hydropower-linked Bitcoin mining allocations while approvals remain pending.
-
Keel stopped Bitcoin mining at Pennsylvania’s Panther Creek site and is pursuing a 350 MW AI campus, while the waste-coal plant remains in an outage and permits are pending.
-
Fortitude’s 15 MW Zcash mine in Aurora, Nebraska, enters Southwest Power Pool’s demand response markets, adding flexibility to grid-supplied cryptocurrency mining.
-
Two solo Bitcoin mining operations found blocks on October 26 and 27, earning nearly 6.29 BTC before service fees. Blockchain records clarify who got paid.
