091. Hash, Heat, and Hardware: LibreBoard, Mujina, and the BitAxe Battle

In this episode, we go deep on two fronts: protecting open-source projects from trademark hijacking and advancing real-world hash rate heating. We share the ongoing battle to oppose fraudulent USPTO filings on the BitAxe mark, why “TM” vs. registered matters, and how we’re navigating opposition, Madrid Protocol options, and the broader goal of keeping open hardware open without enabling scammers. We then switch to practical engineering: Tyler walks us through immersion mining powering radiant floor heat, dynamic performance scaling, control loops with Home Assistant, thermostats and dry coolers, and why tight software control beats expensive hardware band-aids. We unpack LibreBoard and Mujina plans, APIs, Stratum v1/v2 quirks, Intel vs. Bitmain chip behaviors, and how PyASIC/ASIC-RS standardize miner control. We also touch on FreeCAD pains, open-source CAD needs, educational content plans, and a wild idea: launching a BitAxe to low Earth orbit for space-mining experiments. The throughline: building a sustainable, open-source mining ecosystem where entrepreneurs can profit while dismantling proprietary roadblocks, especially for heat reuse at home and in buildings.

Resources we discussed or referenced include: USPTO trademark process and oppositions, Madrid Protocol for international marks, Home Assistant integrations with open thermostats/APIs, LibreBoard and Mujina firmware architecture, BrainsOS and DPS/ATM concepts, PyASIC and ASIC-RS (standardizing miner APIs), FreeCAD/KiCad vs. proprietary CAD, and Dyson Labs’ BitAxe-in-space concept. We wrap with shout-outs to community hashers supporting 256 Foundation and an invitation to contribute, test, and build on these open platforms.
