For an overview on what Wyldcard is, check out the introductory blog post. After spending seven hours in the top position on Hacker News, I decided to crowdfund a Wyldcard DevKit on Crowd Supply

If you have a Wyldcard DevKit, you can program your own functionality and implement game mechanics using JavaScript. (You could also dive into a deeper level and program in any language you want, more on that later)

A simple Wyldcard demo that displays a random image on a card whenever a button is pressed could look like this:

let fs = require('fs/promises')
let path = require('path')

let { Plinth, imageUtilities } = require('@wyldcard/drivers')

async function main() {
  let plinth = new Plinth('devkit')

  let displayRandomImage = function(well) {
    return async () => {
      let image = await imageUtilities.randomImage()
      well.displayImage(image)
    }
  }

  plinth.wells.forEach((well) => {
    well.onAButtonPress(displayRandomImage(well))
    well.onBButtonPress(displayRandomImage(well))
    well.onCButtonPress(displayRandomImage(well))
  })
}

main()

In order to get to running this code, we need to go over the following:

• Setting Up a Development Environment
• Using the Wyldcard JavaScript SDK
• Formatting Images

If you want to design your own Wyldcard-compatible hardware, check out:

• Hardware Documentation

This repo also contains

• Examples and Demo code
• napi-rust-drivers - The core Rust code which runs the Wyldcard e-paper displays and the javascript native api wrappers which form the SDK
• images - Information about images, how to format them, programs for formatting and sending them to the Wyldcard plinth and some sample images to use
