This very cheap off the shelf nostr signing device is designed to work with Lilygos Tdisplay, but you can easily make work with any ESP32.

Data is sent to/from the **Signing Device** over webdev Serial, not the most secure data transmission method, but x1000 better than storing the privatekey on a computer. Clients could support sending to the device directly, but using is Nos2X is far more convenient.

## Install instructions

- Flash the nostr-signing firmware directly from the browser using the [installer](https://lnbits.github.io/nostr-signing-device/)

## Build instructions

- Buy a Lilygo Tdisplay (although with a little tinkering any ESP32 will do) 

- Install Arduino IDE 1.8.19

- Install ESP32 boards, using boards manager

- Download this repo

- Copy these libraries into your Arduino install "libraries" folder

- Open this snsd.ino file in the Arduino IDE

- Select "TTGO-LoRa32-OLED-V1" from tools>board

- Upload to device

## How to use

// Guide to go here

> _Note: If using MacOS, you will need the CP210x USB to UART Bridge VCP Drivers available here https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers_

> If you are using **MacOS Big Sur or an Mac with M1 chip**, you might encounter the issue `A fatal error occurred: Failed to write to target RAM (result was 0107)`, this is related to the chipset used by TTGO, you can find the correct driver and more info in this GitHub issue
