Bounty #2: From Prototype to Production

Last updated on Dec 22, 2023

We’re excited to launch our second bounty to encourage more devs to join the project and to ultimately bring more piggies to market.

PROJECT: LightningPiggy

BOUNTY: 1,000,000 SATS [NOW CLAIMED]

TASK:

Adapt code for new LILYGO ESP32 e-paper development board, reference: T5 V2.3.1 due to obsolesce of the existing T5 2.66 board. Note the new hardware has a smaller screen area of 212x104 pixels, but is significantly cheaper.
Boot-up image: Add a full screen start-up graphic (welcome image including an LP icon and www.lightningpiggy.com web address) for 4 seconds.
New main screen: Update the main (always on) screen to include the following attributes:
Total sat balance.
Last three payments including any associated payment messages.
LN receive QR code.
Small Lightning Piggy icon/text and/or website address.
Battery status (e.g. good/low/charge or no status icon if not connected).

Note: The total sats, last three payments and battery status should update independently of the other fixed screen elements.

Shake to update: Code a ‘balance and transaction update’ interrupt on two suitable pins for an optional “shake to update” feature using an inexpensive vibration sensor, such as this one*.
Physical buttons: Code one of buttons to restart (existing feature), and the other button to update the transaction and balance.
Usage metrics: Include anonymous usage metrics via payment/web hooks linked with the www.linkingpiggy.com website, with the option to opt-out during configuration.
