IMPORTANT: This is not a toy. It contains small parts which could be a choking and ingestion hazard. There are also sharp edges. It should not be handled by children under 4 years of age. Assembly and use of this product is at your own risk. We take no responsibility for any losses that may be incurred.

1. Source the parts

Single Board Computer (SBC): LILYGO T5 V2.3.1 (2.13 inch screen) e-paper device (DEPG0213BN). Available from LILYGo

Rechargeable battery: Voltage: 3.7V Connector: Jst 2pin 1.25mm. Available from Aliexpress

💡
IMPORTANT: Improper assembly and/or the use of improper/faulty batteries can present a fire hazard. We recommend using only high quality LiPo rechargeable batteries.

Case: One homemade case using materials of your choice.

2. Create a wallet

💡
IMPORTANT: LNbits is in Beta. We are not responsible for the LNBits software stack, extensions and any funds that may be lost using this FOSS project.

Create a bitcoin lightning wallet that works with LNbits. We're using this instance for testing and small amounts.

Enable "LNURLp" from the list of wallet extensions and create a new payment link. We suggest deselecting "fixed amount" and adding a 'min' and 'max' amount, so that the sender can choose how much to send.

3. Flash the firmware

Use our custom built web installer to configure and flash the firmware to the device.

You will need the following credentials:

Your wifi "ssid" and "password"

Your "server name" eg "https://legend.lnbits.com"

Your "invoice/read key" eg "db400dfba...." (copied from your LNbits Wallet API toggle)

Works with Google Chrome or Microsoft Edge.

4. Make a case and assemble the parts

Time to get creative! Build your very own LightningPiggy case out of any material you wish to use, and assemble the parts.

💡
IMPORTANT: When installed correctly, the battery and/or board components should not get hot when it is being charged, i.e. the USB is connected to power and the battery is installed.

We're currently working on developing some templates for cardboard pigs, as well as some 3D printed options. If you would like to share your design with others, please email your creation to oink@lightningpiggy.com for inclusion on this website.
