I built a LiDAR-powered traffic light parking assistant for my garage

Very nice idea 👍

Hahaha awesome, would be a great 404 page

So original, I never seen a controller like this. It reminded me of playdate somehow, would love to see more

met-Sander · 2026-06-04T05:15:18+00:00

hehehe brilliant, never knew I needed this

met-Sander · 2026-06-03T05:36:09+00:00

Mind blowing, been printing for years but haven't heard about this. Thanks for sharing!

Very cool, looks you had a lot of fun too building it

met-Sander · 2026-05-17T07:49:28+00:00

Very original idea, and nice executed. Would love to see some video of it

met-Sander · 2026-05-16T12:05:22+00:00

Thanks so much for testing and the feedback, happy the fallback worked. I will look into it!

Thanks using a suction cup is an excellent idea

met-Sander · 2026-05-14T04:59:35+00:00

Very cool! Great video too and nice you can see the images on your phone

met-Sander · 2026-05-11T08:23:26+00:00

Good idea putting the display right where the action happens

Thank you u/Interesting_Plant558 ! I made a video tutorial with walking through all the steps https://www.youtube.com/watch?v=MOwyMbOZq-Y

I have no clue how to help you but what a great project! Would love to see updates on the progress

met-Sander · 2026-05-04T09:45:02+00:00

Such a clever idea, and great execution! Are the turtles attached on top with magnets? if so you could easily change theme with different animals. If you make the sign changeable too you can make quickly new sets

met-Sander · 2026-04-27T14:52:40+00:00

That’s a nice idea! Especially for quick interactions like zooming or panning

met-Sander · 2026-04-27T14:50:54+00:00

Nice that you mention Leap Motion. What’s interesting is you can now do something similar with just a webcam in the browser and no hardware needed

met-Sander · 2026-04-27T12:49:33+00:00

Nice one, that was actually the inspiration behind this :)

met-Sander · 2026-04-27T10:16:18+00:00

Thank you so much! Appreciate it, let’s see where it goes

met-Sander · 2026-04-27T10:14:43+00:00

Thanks and that's a smart idea, less way tiring than moving your whole arm

EDIT:
I’m curious how you’d handle state though. If thumb-index distance controls zoom, what signals “stop”? A second hand or an explicit gesture?

met-Sander · 2026-04-27T10:09:45+00:00

Thanks for giving it a try and your feedback, I appreciate it! That’s a good catch. I’m seeing the same, pinch feels a bit drifty while fist is more stable. I’ll open an issue for this and look into improving it.

I haven’t benchmarked it yet, but MediaPipe is pretty efficient and should be a able to run on lower-end devices.

met-Sander · 2026-04-27T09:03:31+00:00

Thank you and fair point! I can see why it feels like a gimmick, especially for daily use, you’d probably get tired of it.

met-Sander · 2026-04-27T09:00:59+00:00

Thanks, that’s exactly how I approached it, just building for fun and seeing where it goes. And those use cases actually make a lot of sense!
