Flipper Zero, sub-GHz, RFID, and open-source hardware for the sovereign hacker
Three tiers — 400-dollar entry, 2k serious bench, 8k-plus ASIC repair lab — plus a sovereign-stack sidebar. What to buy, what to skip, and where to draw the line before you ship the board to a real repair shop.
One catalog, many shoulders. A directory of the open hardware and open firmware that makes a Bitcoiner home lab actually sovereign — from pocket multitools to ASIC firmware. Credit where due, honest on price and license, no hype.
A practical walk-through of FlipBIP by xtruan — how to install it, how BIP32/39/44 derivation works on the Flipper, what its genuinely good for, and why your meaningful cold storage still belongs on a dedicated signing device.
A practical, non-offensive tour of the Flipper Zero from a Bitcoin miner perspective. Use the open-source dolphin for your own badge duplicates, PSU telemetry, IR diagnostics, and ASIC GPIO probing — not for breaking into things that arent yours.
