You can get just about any gear reduction you want using conventional gears. But when you need to get a certain reduction in a very small space with minimal to no backlash, you might find a wave drive very useful. [Mishin Machine] shows us how to build one with (mostly) 3D printed components.

The video does a great job of explaining the basics of the design. Right off the bat, we’ll say this one isn’t fully printed—it relies on off-the-shelf steel ball bearings. It’s easy to understand why. When you need strong, smooth-rolling parts, it’s hard to print competitive spheres in plastic at home. Plastic BBs will work too, though, as will various off-the-shelf cylindrical rollers. The rest is mostly 3D printed, so with the right design, you can whip up a wave drive to suit whatever packaging requirements you might have.

Combined with a stepper motor and the right off-the-shelf parts, you can build a high-reduction gearbox that can withstand high torque and should have reasonable longevity despite being assembled with many  printed components.

We’ve seen other interesting gear reductions before, too.

godot-rust v0.3 brings type-safe signals to the table.
If you register a signal:

#[signal]
fn damage_taken(amount: i32);

you can now freely connect it with other Rust functions:

fn ready(&mut self) {
    // Connect signal to the method:
    self.signals().damage_taken().connect(Self::on_damage_taken);
    
    // Or to an ad-hoc closure:
    self.signals().damage_taken().connect(|amount| {
        println!("Damage taken: {}", amount);
    });
    
    // Or to a method of another object:
    let stats: Gd<Stats>;
    self.signals().damage_taken().connect_other(&stats, |stats, amount| {
        stats.update_total_damage(amount);
    });
}

Emitting is also type-safe:

self.signals().damage_taken().emit(42);

Furthermore, you can now await signals, effectively introducing async tasks:

godot::task::spawn(async move {
    godot_print!("Wait for damage to occur...");
    
    let (dmg,) = player.signals().damage_taken().to_future().await;
    godot_print!("Player took {dmg} damage.");
});

There are many other improvements, see devlog and feel free to ask me anything :)

Huge thanks to all the contributors who helped ship these features!

Donald Trump on Saturday authorized the deployment of 2,000 national guard troops to Los Angeles, after an immigration crackdown erupted into mass protests for a second day and police in riot gear used teargas on bystanders.

The California governor, Gavin Newsom, said in a statement on X that the federal government was “moving to take over” the California national guard. Newsom said the mobilization was “purposefully inflammatory” and warned that it would “only escalate tensions”.

The defense secretary, Pete Hegseth, wrote on X that national guard troops were being mobilized “IMMEDIATELY” and threatened to send “active duty Marines” if the unrest continued.
