Being the versatile single-board computer that it is, the Raspberry Pi can help you build all sorts of projects with all sorts of accessories. Throw in a camera, and you have a smart doorbell, ...

Abstract: This paper presents a 6.9mW 120fps 28×50 channels capacitive touch sensor for 1mm-φ stylus. A current conveyor analog front-end enables a current signaling before its voltage conversion. A ...

Robust capacitive sensing: TouchLib contains many filters and an advanced state machine to make capacitive sensing more robust Multi-platform: TouchLib works on a range of different boards and ...

Capacitive touch sensors are entirely in the domain of DIY, requiring little more than a carefully-chosen conductive surface and a microcontroller. This led [John Phillips] to ask why not embed such ...

A twenty-sided die (d20) is a common thing in tabletop gaming, and [kati]’s slightly sentient d20 is a PCB that not only delivers random results on demand, but responds to hot and cold streaks and may ...

In this article, we will learn how to build a touch-based color-changing plant using Arduino. When you touch the plant, the color of the plant vase will automatically change. This is a nice indoor ...
