After-party for the Adopting Bitcoin conference held at Edificio Morazan in San Salvador. Over 635 attendees experienced a fully Lightning-powered event featuring interactive hardware installations that accepted Bitcoin payments in real time.
8 local artists participated. Lightning-powered catering generated over $5,000 in revenue. More than 200 Blink wallets were created on-site, and 120+ NFC cards were distributed.
Smoke Machine — LNBits Switch + ESP32 relay. Payments trigger a real smoke machine via Lightning.
Treasure Hunt — Lightning hidden QR code concealed across the venue. Finding and paying it unlocks a reward.
Candy Machine — Dispenses candy on Lightning payment.
Sats Dice — Dice roll game paid via Lightning.
Display Messages — Pay sats to display a message on a public screen.

Plan ₿ Forum at the Marte Museum in San Salvador. A follow-up deployment building on lessons from the Adopting Bitcoin after party, with new and upgraded installations including AI-powered generative visuals triggered by Lightning payments.
Smoke Machine — Upgraded iteration of the LNBits Switch + ESP32 relay system.
Prompt to VJing — TouchDesigner + StreamDiffusion + AI pipeline. A Lightning payment sends a text prompt that generates real-time AI visuals projected at the event.
Treasure Hunt — Lightning-activated lock: finding the hidden QR code and paying unlocks a physical mechanism.
Laser DMX Controller — Laser lighting rig triggered and controlled via Lightning payments.

First European deployment at BTC Prague. The flagship installation was a Pirate-themed Lightning Treasure Chest — a physical puzzle box that emits smoke and releases a mechanical lock upon Lightning payment. The smoke machine was displayed in a transparent case with exposed wiring as an educational exhibit.
Smoke machine booth generated approximately $80 in revenue over the event days.
12 seed words hidden across the venue and at partner booths (with Bitcoin trivia challenges). Words were distributed in sealed envelopes. The final QR code on the chest — once scanned and paid — triggered the ESP32: smoke machine fires, then the electric locker releases.
Collaborated with RockstarDev: 6 treasure chest clones were distributed, but only 3 carried the real password — adding a layer of deduction to the hunt.
Lightning Treasure Chest (Pirate theme) — ESP32, 12V battery, 2 relays: one for the electric locker, one for the smoke machine remote.

A week-long educational residency at PoW.Space in Lugano for 21 students from around the world. The curriculum integrated Lightning hardware deployments with live lectures, hands-on building sessions, and a multi-day gamified treasure hunt.
Guest speakers included Preston Pysh and Efrat Fenigson. Key contributors: Kukks (BTCPay Server), ARK Labs, and Boltz.
Started with BTCPay Server + Blink node. Under classroom load, Blink node response times caused 10-minute latency spikes — root cause identified as Blink node slowness, not BTCPay. Migrated mid-week to LNbits.
Final production stack: self-custodial Ark wallet + Boltz (Lightning interoperability) + BTCPay Server node.
Released a new open-source BTCPay Server plugin during the school: GPIO activation / hardware control through payments. Enables direct physical hardware triggering from BTCPay Server payment events.
Daily reset at midday. Each day's questions were based on the previous day's lecture. 12 keywords collected over the week to form a final passphrase. Decoding challenges included Caesar ciphers, ROT13/21, and SHA-256 hash puzzles.
Baltic Honeybadger in Riga — one of the largest deployments to date, spanning the Chill Zone, Workshop Stage, and an after party at Teritorija (an old abandoned factory). The bar at the after party ran entirely on Ark-powered Bitcoin payments.
Workshop: "IoT Powered by Lightning" — a live breakdown of the smoke machine from hardware to software, on the Workshop Stage.
After party performers: Rockamoto, Rolling Dynamite, Mark Kadek, and a fire show. Treasure hunt: 2 winners.
Giant Honeybadger Head — Custom large-format prop that emits smoke on Lightning payment. Signature installation for the event.
Smoke Machine — Standard deployment, booth at the conference.
Flying Photo Booth — Takes and distributes photos triggered by Lightning payment.
Treasure Hunt Chest — Lightning-activated treasure chest with multi-location puzzle.
Ark-Powered Bar — The entire after-party bar accepted Bitcoin payments via Ark, with no Lightning channel management required.
