Raspberry Pi Zero 2 W Bluetooth-to-USB HID Bridge

While Bluetooth keyboards are very common and often have a button to switch between multiple devices, I came across two major limitations. First, I sometimes need to access the BIOS/UEFI, which is not possible with a Bluetooth keyboard. Second, I use a single keyboard across three computers, one of which is dual-boot. Because the dual-boot machine acts as two separate devices, I have run out of available slots on my keyboard, which can only switch between three devices.

Motivation

Problem 1: Using Bluetooth keyboard with a multi-boot PC

Problem 2:

	#!/bin/bash
	# Install custom "Show Applications" launcher in Ubuntu
	# Based on
	# https://github.com/milanify/Ubuntu-Launchpad

	echo "Installing Show Applications launcher..."

	DESKTOP_FILE="/usr/share/applications/show-apps-launcher.desktop"

	# Create .desktop file

	# Init PowerShell GUI
	Add-Type -AssemblyName System.Windows.Forms

	# Create a new form
	$GUIform = New-Object system.Windows.Forms.Form
	$GUIform.MaximizeBox = $false # no maximize
	$GUIform.FormBorderStyle = 'Fixed3D' # no resize

	# Define the size, title and background color
	$GUIform.ClientSize = '500,300'

	#!/bin/bash
	# Install and fix issues of xrdp on Ubuntu (tested on 22.04)
	# v1.0.0

	rem Recursively find and replace files
	rem This script starts from current directory recursive search for the file name given in the first parameter and replace it (keeping its name) with the file given in second parameter.
	rem source: https://stackoverflow.com/a/10423757
	rem usage: fr.bat targetName replacementFile
	rem example fr.bat test1.txt c:\data\replacementfile.txt would recursively search for "test1.txt" and replace it (keeping its name) withe the file "c:\data\replacementfile.txt"

	@echo off
	set targetName=%~NX1
	set replacementFile=%~F2
	call :processFolder
