Rework your espresso desk into a chunk of kinetic sand artwork

Like most furnishings, a espresso desk ought to each look good and performance effectively. To perform effectively, a espresso desk simply wants a flat floor. However trying good is much more sophisticated and relies upon solely on proprietor style. If kinetic artwork is your factor, then you definately would possibly think about constructing this computerized sand artwork espresso desk.

This can be a espresso desk with a big pocket within the heart stuffed with sand. A ball bearing rolls round within the sand, leaving intricate patterns behind. LED lighting highlights these patterns and customers can program their very own sequences of actions to create no matter artwork they like.

The key to a kinetic sand espresso desk like this one is magnetism. There’s a two-axis CNC system beneath the desk with a robust magnet that pulls the ball bearing by the sand. On this case, the kinematics are simple with a linear rail gantry driving on a pair of linear rails. Stepper motors pull the gantry and carriage with GT2 belts.

An Arduino UNO Rev3 board controls these stepper motors by a CNC Defend V3 with two TMC2209 drivers. The sketch could be very easy and doesn’t run G-code instantly. As a substitute, the person should extract a sequence of coordinates from a G-code file and replica them into the sketch. However as a result of it is a espresso desk, most customers will solely want to try this one time to program a sequence of patterns to cycle by.
