Bitcoiners will HODL through anything…. Except for when there’s pizza on the menu. This beauty (and the one I already gobbled) set me back just 10,000 bitcoins! Worth every sat. No regrets! 🍕⚡️🐽 #BitcoinPizzaDay image

Firmware version 6.3.0 is out and running slicker than a greased pig at a county fair! Producing this update has been non-trivial, involving complex integration and feature work, building UIs in LVGL and introducing a load of Library and IDE updates. Here are all the juicy tidbits: General User Experience Improvements: * Added automatic captive portal redirection for easier setup. * Shortened access point name for configuration mode (now Piggy Config). * Enhanced the look of the configuration login page. Library Updates: * Adafruit BusIO: 1.15.0 → 1.17.0 * Adafruit GFX Library: 1.11.9 → 1.12.0 * ArduinoJson: 7.3.0 → 7.4.1 * AsyncTCP: 3.3.3 → 3.3.8 * ESPAsyncWebServer: 3.6.2 → 3.7.6 * GxEPD2: 1.5.6 → 1.6.3 * TFT_eSPI: 2.2.20 → 2.5.4 * arduino-esp32: 3.1.1 → 3.2.0 * ESP-IDF update: 5.3.2-282 → 5.4.1-1 You can install it using the Web Installer. If you’re already on version 5.x or later, your existing configuration will be preserved during the upgrade. Enjoy the update! Stay humble, hog sats!

Some new experimental piggy hardware (ESP32-S3-LCD-2-C) has just arrived but unfortunately, the camera mount has been installed backwards at the factory, making it impossible to connect the OV5640 camera ribbon. Oh Grunt! Back to rolling about in the mud while we get this sorted! ⚡️🐽 #LightningPiggy #STEMM #BitcoinKids #BuildInPublic #bitcoin

While fiat savers are wallowing in the mud, @LightningPiggy keeps on shipping! Check out our latest v6.2.0 update, it’s a meal of new user experience improvements. For starters, the device now displays the exact day and time it last checked your wallet; updated every minute in "no_sleep" mode. Talking of “no_sleep” mode, for main course, you can now choose the vibe that suits your power source: - "no_sleep" – always awake (great for mains, solar, and big batteries) - "custom_sleep" – default 6-hour snooze (perfect for batteries, solar and custom set-ups) - "endless_sleep" – deep hibernation with shake-to-wake (perfect for small batteries!) Here’s the full change log: User Experience (UX) Improvements - Detailed startup feedback: The device now shows real-time status updates during startup (e.g. connecting to Wi-Fi, syncing time, launching webserver, fetching wallet data). - Always-on clock display: The current time is now continuously shown while the device is powered on, not just before going to sleep. - Localized weekday names: Weekday names are once again translated into your local language. - Configurable sleep modes (Feature Request #35) detailed above. - Last wallet check timestamp: The device now shows the date and time it last checked your wallet (updates every minute in no_sleep mode). Fixes & System Enhancements - Switched to standard NTP: All time synchronization now uses pool.ntp.org, removing the dependency on timeapi.io. - Automatic Wi-Fi reconnection: The device will now attempt to reconnect automatically if Wi-Fi is lost. - Periodic auto-restart: The device now performs a daily (every 23 hours) restart to proactively avoid potential issues. - Cross-platform build support: The same firmware build now runs seamlessly on both physical and virtual (QEMU) ESP32 devices—no recompilation needed. You can install it using the Web Installer, which has now hit a milestone—no known open issues! If you’re already on version 5.x or later, your existing configuration will be preserved during the upgrade. Enjoy the update! Stay humble, hog sats!

Hot on the hoofs of our last major update, v6.1.0 has just landed, bringing 100% feature parity between LNBits and Nostr Wallet Connect (NWC) —empowering users with greater choice and convenience as they start receiving their first zaps and saving on the bitcoin standard! In short, going ‘full Nostr’ means you won’t have to deal with any boar-ing limitations, just smooth P2P (Peer-to-Piggy) connectivity! 🐽 Change log: * Nostr Wallet Connect: Added support for NIP47 payment notifications for instant updates! Now, when a payment zaps in, your wallet balance(s) and updated list of payments will be displayed immediately - no more wallowing around waiting! * Fixed issue #30: When a payment comment is missing, “Null” messages are a thing of the past, because we don’t want our logs looking like a muddy mess! (Thanks @Jurjen de Vries for reporting the bug!) Much of the hard work for this update involved adding support for payment notifications to the Nostrduino open source library. Furthermore, we’d like to thank @Mysterious Hamster for proactively working with us to enable these features. Enjoy the update! Stay humble, hog sats!

🥁 Drumroll, please! 🥁 We’re thrilled to announce the integration of Nostr Wallet Connect (NWC) into LightningPiggy! Now, you can seamlessly your Lightning Piggybank directly to any NWC-enabled wallet, unlocking a whole new world of funding sources. With effortless setup, smooth transactions, and even more ways to hog sats, saving on a bitcoin standard just got easier. LightningPiggy was the first piggy bank to accept bitcoin over lightning thanks to @LNbits. Now, we’re the first to connect with the fast growing Nostr ecosystem, thanks to @npub19hg5...yv9p! You might want to build one yourself, in case it catches on!⚡🐽 Our lead developer, Thomas, has been firing on all cylinders. A large part of the effort involved improving Nostrduino, optimising it for low-memory microcontrollers like the ESP32, which powers our project. This involved fixing bugs, improving performance, and adding essential features to meet our needs. For reference, here are 10 related pull requests showcasing these improvements: Additional improvements that come with this v6.0.X release include: - Added NWC URL to the configuration page for easier wallet connection. - Improved help text on the configuration page for better clarity. - Enhanced timezone selection by adding GMT offsets for more precise setup. - Displayed IP address after connecting to an access point as a client. - New functionality for the General Purpose (IO39) button: • Short press refreshes the balance (like the tilt sensor). • Short press skips the wait time during the logo/boot wisdom display. - Optimised Wi-Fi connectivity with a full network scan, automatically selecting the strongest access point.
