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! ⚡️🐽

Thank you @nprofile…ct3f for having our project feature on your bi-weekly @nprofile…fy4z call ✊ It’s an honour to be part of such an inspiring community of builders!

🥁 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 @nprofile…qgpe. Now, we’re the first to connect with the fast growing Nostr ecosystem, thanks to @nprofile…g9lp! 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: https://github.com/riccardobl/nostrduino/pulls?q=is%3Apr+
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.

This usually happens because of the cable. You need one that transmits both power and data. Change it or check it’s a data cable by connecting it with a hard drive, or anything else that works with data.

Okay, does anything happen when you do that?

Shining a light on sound money: This Minecraft-inspired savings' lamp, a first of its kind, was ingeniously crafted by silexperience@iris.to and his son. The project was sparked by Silexperience’s son asking, "Can bitcoin be in a piggy bank?" This led to the idea of integrating a LightningPiggy device inside a block shaped lamp.
We love how the LightningPiggy device can seamlessly integrated into any object and in this case it looks like an artefact of the bitcoin blockchain.
