Small xy stage

This is a small xy stage, with a movement of 2.4 mm (less than 1/10") in x and y direction.

It is built with this $5 product from aliexpress, [two-axis sliding table](https://www.aliexpress.com/item/32972295033.html), part of motion compensation for a camera.

The stage is 75x25mm, the size of a microscope slide. I've written an arduino sketch that moves the stage around using the WASD keys, like a videogame. [Schematic and arduino sketch](https://github.com/koendv/xy-stage)
