Christmas has come early 🎄 Huge thanks to the @LNbits community for making it even easier to configure LightningPiggy 2.0 with LNbits. With LNbits v1.4, the server name is now viewable as an optional QR. That means configuring LightningPiggy 2.0 with LNbits as its wallet now requires just two QR codes to scan. And the entire setup can be done on a mobile phone. We’d like to take this opportunity to thank everyone who has supported the project along the way. It’s been humbling to see the excitement and joy on kids’ faces (young and old!) receiving zaps on their piggies. We’re excited about what’s ahead and can’t wait to build, ship, and share even more in the year to come. Wishing you and your loved ones a very Merry Christmas! Let’s make sats the savings standard for every child ⚡🐽 Team LightingPiggy image

Freedom Farm News: Oink-credible news for LightningPiggy 2.0 owners! MicroPythonOS, the belly of the beast, has been freshly upgraded with some seriously tasty improvements. Time to tuck in ⚡️🐽👩‍🌾 MPOS 0.5.1 Release Highlights A brand-new Camera experience The Camera app has received a major overhaul with new Basic, Advanced, and Expert modes. Scanning QR codes is now dramatically more powerful; even tiny, high-density codes (like Nostr Wallet Connect) on phone screens, damaged images, or codes with logos and dots are decoded reliably. Better image handling You can now delete images directly from ImageView, and grayscale images are fully supported. Smarter updates & connectivity System updates now automatically pause if Wi-Fi drops and resume when you’re back online. The Wi-Fi app also feels smoother thanks to improved keyboard handling and fixed cancel behaviour. Improved hardware support Fri3d Camp 2024 boards gain startup light and sound feedback, more accurate battery readings, and full support for the WSEN-ISDS 6-axis IMU — including temperature sensing. More control Storage usage is now visible in the About app, IMU calibration has been added to Settings, and the back-swipe gesture intelligently closes the top menu when it’s open. Under-the-hood improvements New audio, lighting, and sensor APIs unlock richer apps, smoother animations, and better hardware integration across the system. Credits * @Nostradamus * Mark19000 ref.

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
