We’re rebuilding our drivetrain before our first scrimmage. The robot is about 13 lb and our current setup feels quick on tile but loses a lot of speed on carpet. For teams using 4-inch wheels, what gear ratio gave you a useful balance of speed and pushing power? I’d love to hear what you tested and what you’d change.

I made a three-minute piece around a cereal-box camera obscura. The image is rough, but the moment the room appears upside down is still my favorite part. I’m deciding whether to explain the trick at the end or leave the audience with the image. If you watched it, what would make the ending feel earned?

We’ve been trying to keep project notes useful without turning every experiment into a report. What do you write down after a test fails? A photo and one sentence? Measurements? The guess you started with? I’m curious what actually helps you pick the work back up a week later.

When I share an early cut, I’ve started asking one specific question instead of saying “any thoughts?” A few prompts that have helped: Where did your attention drift? What do you think the person wants in this scene? Which moment should have more room? What question gets you the most useful feedback?

We checked the sprocket alignment and tension by hand, but the chain still walks off after a few hard starts. What should we inspect next?

This week we filmed a mechanism rebuild using only workshop sound and short on-screen notes. The footage feels calmer, but two steps are probably hard to follow without narration. We’ll post a rough cut after we get the edit together. Has anyone found a good balance between showing the work and explaining it?

We shared a short build diary about one mechanism decision and the tests that shaped it. It made us wonder how other teams choose which idea is worth building first. Do you reach for cardboard, CAD, or a quick physical mockup? We’d love to hear what has helped your team learn something early.
