LoRa protocol explained: chirp spread spectrum, spreading factor vs range, regional bands, LoRa vs LoRaWAN, and real-world range math for sovereign Bitcoiner comms.

Bitcoin over Meshtastic with BTC Mesh (eddieoz): sign PSBTs, relay over LoRa mesh, broadcast to the Bitcoin network with no ISP. Use cases, limitations, walkthrough.

Off-grid mining comms with Meshtastic: site node, relay, base station, MQTT bridge, and emergency shutoff — so your remote Hashcenter stays reachable when the ISP dies.

Bitcoin solved money. Your social graph, your identity, and your speech still live on corporate servers. Nostr — Notes and Other Stuff Transmitted by Relays — is the identity layer that finishes the job. Here is the pleb's primer.

A Nostr relay is a dumb WebSocket pipe that stores signed events and forwards them to subscribers. Running your own is the single most sovereign thing you can do on the network. Here is the pleb's guide to strfry, nostr-rs-relay, and how to ship one that…

A zap is a Lightning payment stapled to a Nostr note. NIP-57 specifies the handshake. The result is the first native monetization primitive the open web has ever had: no ads, no platform tax, no KYC. Here is how it works and how to turn it on.

If you are already running your own inference stack, Nostr is the identity layer you did not know you needed. npub-auth replaces API keys, zaps-for-prompts replaces credit cards, and signed model output gives you cryptographic provenance on every response.

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.

FlipBIP is xtruan GPL-3.0 BIP32/39/44 application for the Flipper Zero. It turns a pocket multitool into an experimental offline Bitcoin wallet — great for testnet, burner wallets, and air-gapped dev work.

A practical catalog of open-source hardware that belongs in a sovereign Bitcoiner lab. Flipper, HackRF, ProxMark, Pwnagotchi, ESP32, SeedSigner, Bitaxe, and the firmware ecosystem around them.

A pragmatic, tier-by-tier buying guide for the tools a Hashcenter operator actually uses — from a 25-dollar multimeter to an 8000-dollar reflow oven. Budgets, part numbers, and honest notes on when DIY stops.

An open source multi-tool for exploring and publishing data
