Maker Turned a ToF Sensor Into a 3D Scanner What if a small sensor could understand space in three dimensions? A maker recently showed how a Time-of-Flight (ToF) sensor can be turned into a basic 3D scanner. The sensor sends out infrared light and measures how long it takes to return, a method known as time-of-flight distance measurement. By using a multi-zone depth array, it captures several distance readings at the same time, creating… |

A Smart Macro Pad with Haptic Feedback Ever thought of controlling your computer using buttons and a knob that actually feel different when you use them? Most input devices, like keyboards and mice, only give visual feedback on the screen and do not provide any physical sensation to indicate how an action feels. The Macropad changes this experience by adding the sense of touch to everyday computer controls. This is a six-button… |
