An electronic cash piggy bank for children that accepts bitcoin sent over lightning, while displaying the amount saved in satoshis.

It’s a DIY kit. We’re checking if we have a ready painted and assembled V2 for you.

Together, let’s make 2026 the year sats become the savings standard for every child - one piggy at a time ⚡️🐽

Christmas has come early 🎄

Huge thanks to the nostr:nprofile1qqs8u5uf0rd2p9wmdxxaznpn54tkq8wwspmljy0cjqw6jdgm5kv84dspp4mhxue69uhkummn9ekx7mqpr3mhxue69uhhyetvv9uju6rfva5xc6t8dp6x2u3wvdhk6tcqkd3u4 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 ⚡🐽

Thank you Simon. We love what you do too ⚡️🐽

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.

ImageView App

* Improved error handling and overall robustness

Settings App

* Tweaked font sizing for improved readability

* Added new option: “Format internal data partition”

* Fixed checkbox + button interaction issues

UI / UX Improvements

* Pass-through: clicks on the invisible “gesture swipe start” area are now correctly forwarded

* Back/down gesture icons now show only during swipe, not on tap

* Doubled the size of the back/down gesture activation zones

* Increased overall gesture sensitivity

* Fixed visual glitches during UI animations

API / System

* Added instrumentation hooks (screengrabs, mouse-click simulation)
