rtl_433 on Raspberry Pi using RTL-SDR Blog V4 hardware

I technically began by following this guide but rtl_433 was unable to decode any packets, so I researched and found that the RTL-SDR Blog V4 hardware requires a relatively new driver from 2023.

Therefore the following guide is derived from the above guide combined with instructions from https://www.rtl-sdr.com/V4/

New guide for 2024

Begin with a fresh install of Raspberry Pi OS.

A guide to complete the Super Mario RPG 100 Jump challenge on Nintento Switch, using a Raspberry pi and a servo to press the A button.

Super Mario RPG has a challenge to complete 100 consecutive jumps on a single enemy. The reward is a powerful piece of armor for Mario.

It is recommended to do this in Mushroom Way (the zone directly after Mario's Pad), where you can find Spikey enemies which take no damage from jumps, allowing you to try again and again without re-entering combat with other enemies. Plus, there is a mushroom in a chest in the area northwest of the spikeys so you can refill on flower power!

I couldn't get beyond 30 jumps doing it by hand, so I found another way.

Moving Windows Recovery Partition

When cloning a Windows OS disk to a larger disk, it is common for the OS partition to be followed by a recovery partition. If your disk cloning software does not allow moving the recovery partition, or you forget to do it, it is possible to fix it from within Windows later.

It is possible to move a Windows Recovery Partition without third-party software and without shutting down, for the purpose of extending the OS partition before it.

How to change Windows font rendering / cleartype / subpixel antialiasing for displays with BGR, WRGB, and other subpixel layouts.

Purpose

Most computer monitors use an "RGB" subpixel layout, so most computer software (including Windows itself) optimizes its text rendering to look good on this kind of display. However this kind of optimization starts to become undesirable in many situations, where it causes color fringing to appear around text.

Changing font rendering settings in Windows

Method 1: ClearType Tuner

Use the ClearType tuner: Windows > Settings > search: Cleartype

To add a Windows context menu item "Edit With GIMP", download RegEditWithGimp.reg, edit the version number in the exe path to match your actual GIMP exe, and then double-click the reg file to install it into the registry.
