, “Dot-Dot-Tilt! can simulate flowing sand or a rolling dice, all managed interactively by tilting the machine.” It’s a refreshingly easy amusement. Simply flip it on and set it on a degree floor for calibration. You possibly can then select to regulate both a rotating 3D dice or a sand simulation on its LCD display screen.
The Dot-Dot-Tilt! duties an MPU-6050 module for degree sensing, together with a Seeeduino XIAO SAM D21 dev board for processing. A small 128×64 pixel decision EA DOGM128W-6 LCD show is used to point out both the dice or sand simulation. Elements carried out characteristic pretty low energy necessities, permitting it to be provided by solely a single coin-cell battery.
A laser-cut acrylic case completes the construct, which is a somewhat pleasing design. Construct recordsdata for the machine’s PCB and case are , in addition to the code when you’d prefer to peruse this design, or construct your individual. The machine, operating each the sand and field simulations, is demonstrated properly within the video under.
After all, when you do resolve to choose up this construct and run with it, Gabor has a couple of enchancment concepts, together with enhanced gesture detection, hiding the (should-be) invisible edges of the dice, and doubtlessly even new video games. He’d additionally transfer the IMU to the center of the PCB for improved sensing if ranging from scratch. It is one thing to bear in mind when you make your individual motion-based machine, impressed by this one or not!
