111. Open-Source Overdrive: Mujina Breakthroughs, Public Pool’s First Block, and LibreBoard v3

About this episode

The episode discusses advancements in open-source hardware for Bitcoin mining and celebrates recent successes in solo mining.

In this episode, we kick things off with the joys and perils of being “nerd‑sniped” by new open-source hardware ideas—from sketching a $20 USB Bitcoin miner concept we jokingly dubbed Bitaxe Latte, to unveiling a tiny AC Infinity fan adapter board that lets miners control powerful, quiet duct fans via standard 4‑pin headers. We dive into firmware nuances, like PWM frequency tweaks and RPM reporting workarounds using Mujina, and how open-source collaboration accelerates progress across the stack. We celebrate a big week for solo miners: three blocks found in just a few days (4 blocks as of publishing): CKPool (x2), Public Pool’s first hosted-instance block, and Node Runners’ pool—while unpacking pool mechanics, coinbase verification protections in AxeOS, and why transparent, GPL-aligned software matters. We also share April roadmaps: HydraPool improvements for password-field difficulty/hashrate hints and better logging; Mujina’s push toward a universal Bitmain-chip driver; and LibreBoard v3’s power design updates. Rounding out the shop talk, we swap stencil printer and solder paste tips, touch on Ember One v6.1 reliability upgrades, ASIC RS community growth, Telehash/Austin plans…
