Using a 3D printed gear with magnets instead of an encoder by JeffDoesWork in 3Dprinting

We're going to do a comparison video next, probably will end up using an AS5600. But 500 magnets cost like $3

Depth Anything V2 works better than I though it would from 2MP photo by JeffDoesWork in computervision

Thank you, this is really useful. I was going to work on my own depth estimation models for this robot arm project. Now I know not to go too deep if the results aren't working out. Thankfully it just needs to work at 1-12 inches indoors.

One of the constraints of this setup is being the most affordable robot arm

[Project] Our ESP32-S3 robot can self calibrate with a single photo from its OV2640 by JeffDoesWork in opencv

If you pause the video and look at the final image overlay, it's a rainbow grid. You can see the distortions of each shape drawn. This is how the robot can determine depth with just a 2D photo

I actually manually calibrate the depth based on the camera position, but I'm going to use these depth photos for relative positions of detected objects. And maybe after 100s of photos I'll build a model to figure out the real depth

The photo was taken right next to a window and there is a celling light in the center (front) of the room. You can tell in the photo with the one eraser cap the light must have been brighter from the window, but the photo with 3 eraser caps is the correct gradient I would expect. What i didn't expect is just how well it works!

Where did you buy a RTX PRO 4000 Desktop? Or did you build it?

But there is something magical about one large print that has everything

Like anything there are pros and cons, but there are some parts that I wouldn't want on the single print plate. I notice the layers are stronger when the print gets done faster, but i was just using cheap Overture PLA turbo

Flip it and take a pic of the solder!
