AMD GPU On Raspberry Pi

I've been playing with Home Assistant Voice and it's too slow on the hardware I've been using (mostly Raspberry Pis and similar SBCs). I saw Jeff Geerling had gotten external GPUs working on a Pi, so decided to have a go...

Hardware

  • Raspberry Pi 5 8GB
  • PCIe to NVMe board
  • NVMe to Oculink board
  • External PCIe x16 board with Oculink
  • Asus AMD RX480
  • Corsair 550W PSU

JS is odd
const myMutator = (theObj) => {
const objClone = {...theObj};
objClone.primProp = 2;
objClone.objProp.value = 'mutated!';
};
const myObj = {
primProp: 1,
objProp: { value: 'original' }
};

DDNS in Cloudflare using bash/curl/jq/ipify - Only calls Cloudflare when IP changes and ipify has no rate limit so can be run as often as you like. Requires an ini file in the same format as certbot cloudflare-dns plugin
#!/usr/bin/env bash
ini_file=$1
dns_zone=$2
domain=$3

A random string generator, useful for passwords and the like. Created in Node.js, but as far as I can tell with work in browsers as well
/**
* Random String
*
* Generates a random string of specified length using charSet.
*
* Optional charSet can either be a RegExp MATCH or String of allowed characters
* if not provided then (nearly) all characters on a UK Keyboard will be used.
*
* @param {Int} len Length of random string
* @param {String|RegExp} charSet The character set to use
