This little thing is 22.5mm x 18mm. It connects to WiFi, talks to a BTCPay Server, and can trigger anything when it receives a Lightning payment. Love it!⚡️
The ESP32-C3 SuperMini. Tiny board, big ideas.

Me: sees any device with a button
My brain: "What if it was Lightning-activated?"
Hacking a regular remote to trigger it with a sat payment ⚡
ESP32 + @BtcpayServer + soldering iron = magic 🔧
"To the moon" they said...
Chun Wang @satofishi took it literally. The f2pool co-founder sold BTC to fund an entire SpaceX mission and commanded the first crewed polar orbit flight. Just an OG miner with sats and a dream!

3 lessons from building Bitcoin hardware for live events ⚡
#1 Don't Trust, Verify! Worked at home ≠ works on-site
#2 Batteries always die at the worst moment. Carry spares!
#3 Event wifi will crash. Have a backup. I bring a Starlink!
NEW: SIM Swap Protection that works like Bitcoin Wallets 👀⚡️

Lesson on Bitcoin circular economies by @JoeNakamoto in the @planb_network Business Track.
Education before wallets, leaders must be local, solve real problems, let adoption grow from the ground up.
Makes you want to go see it for yourself!
Free course!
Today I'm giving a talk to the Business track of Plan B Network on bitcoin communities + economies
i fed my entire youtube channel + transcripts of the top 10 circular economies vids to Claude then had a big conversation with it
here are two slides that you can learn from
I built and deployed 3 Lightning-powered hardware systems at Plan ₿ Forum 2026 in El Salvador.
-> 194 transactions
-> 191,818 sats processed
-> Zero custodial services
Here is what I built. 🧵
All of this runs on open-source software: @BtcpayServer, BitcoinSwitchFirmware, @lnbits
The hardware is built around ESP32 microcontrollers.
I started documenting the full build process for each device so anyone can replicate these setups for their own conferences and meetups.
The final lockbox: ESP32 mini + MOSFET transistor as relay + 12V to 5V power adapter + resistors + magnetic lock, all in a 3D-printed enclosure
The lock opens when you enter the 12 seed words!
Yes, we need "builders" all right!
But not for fancy, novel, shining "use cases": for trivial, boring, basic-bitch ones, which are still shitty!
We don't have decent and simple tooling yet for acquiring sats, hodling sats and spending sats, with some minimum level of privacy and state-resistance (which is the ONLY reason for Bitcoin to even exist in the first place).
And you dream of subsidizing a new wave of bored Silicon-Valley kids with anxiety issues and pronouns in bio, to further waste our time hyping "smart contracts", "NFT" scams, "agentic" bots and "Quantum" nonsense? Fuck them. They can stay in the current-thing fiat bubble.
We need cypherpunk engineers with long-enough attention spam to focus on real, boring things.
It's 2026, and when a normie asks me a tool to use Bitcoin properly, I *don't* have a clean, simple answer.
I teach them to stack sats avoiding KYC, but bisq and robosats and vexl are far from perfect and standard. People use shit like binance.
I teach them to hodl keys properly, but airgapping and multisig with coldcard, seedsigner, liana, sparrow, nunchuck are far from perfect and standard (let alone if they want to manage inheritance).
I teach them to use the Lightning Network to pay small amounts, but really usable LN last-mile security models, like arks and mints, are still early and don't have good tooling yet, and wallets with decent, contact-based UX, like Blitz, are still niche and experimental.
I teach them to run nodes instead of blindly trusting third parties and leaking sensitive information, and to conjoin from and to cold-storage, but even with node-in-a-box tools like Start9+JAM, syncing a full node is still terrible UX, and running joinmarket effectively far from trivial.
And what about having all those things in a single consistent app or framework? Still a wet dream!
Fuck your imaginary, scammy "new use cases". Shitcoins already exist for those. Let's fix the real ones.
