113. Touchscreens, Thermostats, and Doom: A Weekend of Open Mining Hacks

In this episode, we go deep on a wild weekend of open hardware hacking across the 256 Foundation community. Skot walks us through getting Mujina running on an S19j Pro with Wi‑Fi via a hidden USB port, plus a USB hub and a repurposed open source touchscreen to display live hashrate, temps, and fan data—laying the groundwork for a tidy, Wi‑Fi‑connected, touchscreen miner retrofit. We also riff on AI‑assisted CAD and browser automation for rapid prototyping, and brainstorm practical home‑heating integrations: using LibreBoard as the bridge between standard 24V thermostats and miners, ramp control vs. binary heat calls, PID loops, and the real limits of tuning frequency on different firmwares and machines. Beyond the bench, we celebrate Schnitzel’s Doom-on‑LibreBoard test, discuss the path to open firmware on WhatsMiners, and the hardware hacks that open firmware makes obsolete (farewell, trick boards). We hit PSU mods for 120V, LuxOS’s new “ignore PSU link” option, Stratum V2 progress including BlitzPool’s solo pool and non‑custodial PPLNS roadmap, and what a node‑native, open, block-template app could unlock. We close by shouting out OpenSats’ Open Hardware Impact report (Bitaxe, BitShoka/BitSoka Nini), recent hardestblocks.org features, the growing roster on dash.256f.org, and community builds from BitForge Nano to filament dryers heated by hashrate. Catch the 256 crew live in Vegas next week for panels on open hardware and human rights.
