Tutorials/Automatic respawn anchor recharger

In Java Edition 20w12a, the Respawn Anchor was added to the game. Back then it could only be loaded/charged by hand however now thanks to changes in 20w13a it can now be loaded using a dispenser. This means it can now be automated! Because observers detect the block update of a respawn anchor, it is actually quite simple. All that is needed is to add a observer facing into the respawn anchor, then lead redstone dust from the back of the observer into the dispenser with glowstone inside.

Materials

 * 3 pieces of redstone dust
 * An observer
 * A dispenser
 * 2-3 stacks of glowstone
 * A respawn anchor
