Gesture Control without Fancy Sensors, Just Pots and Weights

[Dennis] aims to make robotic control a more intuitive affair by ditching joysticks and buttons, and using wireless gesture controls in their place. What’s curious is that there isn’t an accelerometer or gyro anywhere to be seen in his Palm Power! project.

The gesture sensing consists not of a fancy IMU, but of two potentiometers (one for each axis) with offset weights attached to the shafts. When the hand tilts, the weights turn the shafts of the pots, and the resulting readings are turned into motion commands and sent over Bluetooth. The design certainly has a what-you-see-is-what-you-get aspect to it, …read more

Food-grade 3D printing filament is on the rise and it is nice to have a custom coffee mug in the office to instill a little envy in the locals. [Stefan] took it upon himself to create a Mocha Machine that he would 3D print and test the boundaries of his filament.

[Stefan] used Fusion 360 to replicate the famous Bialetti Moka Express pot in it true octagonal shape. Since the pot brews coffee under pressure, he tested tolerances in Fusion 360 to make sure all the thicknesses were right. While the design was being printed, a steel washer was added …read more
