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.

LightingPiggy is an electronic cash piggy bank for children, that accepts Bitcoin sent over the Lightning Network. It displays payment amounts, messages, and the total satoshis saved.

Our vision is to make bitcoin the savings’ standard for every child, while creating an educational platform to inspire future generations, not only to save in bitcoin, but also to learn to code and build in a free and open-source way.

We had an amazing time at @BTCPrague’s Kids’ Corner, where we built piggies and created some unique characters. The children were incredibly creative and worked well together. Check out their proof-of-work (shared with permissions).
