Ah.
Je vais essayer, je vous dirai comment réagis mon stepper.

Peek Behind the Curtain of this Robotic Mouse

At first glance, this little animatronic mouse might seem like a fairly simple affair. A door opens, our rodent friend pops its head out, looks around, and goes back in. But just like in The Wizard of Oz , a strategically placed curtain is hiding the impressive array of gadgetry that makes the trick possible.

Creator [Will Donaldson] has put together a fantastic write-up of just what went into creating this little fellow, and we think you'll be surprised at just how serious the mechanics involved are. Take for example the rig that provides horizontal motion with a NEMA 17 stepper motor mated to a 200 mm leadscrew and dual 8 mm rail assembly that would like right at home as part of a 3D printer.

The star of the show rides atop a beefy sliding carriage assembly made of printed components and acrylic, which is linked to the door via a GT2 timing belt and pulley in such a way that it automatically opens and closes at the appropriate time. To inject some life into the puppet, [Will] stuffed it with a pair of SG90 servos in a sort of pan-and-tilt arrangement: the rear servo turns the mouse's body left and right, while the forward one moves the head up and down.

An Arduino Uno controls the servos, as well as the stepper motor by way of a TB6600 controller, and optical limit switches are used to make sure nothing moves out bounds. [Will] is keeping the CAD files and source code to himself for the time being, though we imagine a sufficiently dedicated mouseketeer could recreate the installation based on the available information.

This would appear to be the first animatronic mouse to grace the pages of Hackaday, but we're certainly no strangers to seeing folks imbue inanimate objects with lifelike motion.

You Need an Automated Overhead Camera Assistant

It's 2021. Everyone and their mother is filming themselves doing stuff, and a lot of it is super cool content. But since most of us have to also work the video capture devices ourselves, it can be difficult to make compelling footage with a single, stationary overhead view, especially when there are a lot of steps involved. A slider rig is a good start, but the ability to move the camera in three dimensions programmatically is really where it's at.

[KronBjorn]'s excellent automated overhead camera assistant runs on an Arduino Mega and is operated by typing commands in the serial monitor. It can pan ±20° from straight down and moves in three axes on NEMA-17 stepper motors. It moves really smoothly, which you can see in the videos after the break. The plastic-minimal design is interesting and reminds us a bit of an ophthalmoscope -- that's that main rig at the eye doctor. There's only one thing that would make this better, and that's a dedicated macro pad.

If you want to build your own, you're in luck -- there's quite a lot of detail to this project, including a complete BOM, all the STLs, code, and even assembly videos of the 3D-printed parts and the electronics. Slide past the break to check out a couple of brief demo videos.

Not enough room for a setup like this one? Try the pantograph version.
