Wired USB keyboard, mouse, controller to Bluetooth w/ $6 Raspberry Pi Pico W

Add Bluetooth to any wired keyboard, mouse, gamepad, joystick, or any USB Human Interface Device using an affordable Raspberry Pi Pico W, USB extension cable, and USB power bank. This DIY project allows wired peripherals to connect over Bluetooth Low Energy (BLE) for wireless operation with inexpensive components. In principle, connecting multiple devices through a USB hub should work, but compatibility will vary with the specific devices, hub, power source, and the OS of the machine it is connected to.
