Here is a design concept for a cheap single point optical liquid sensor that can detect the presence or absence of certain colored liquids inside a transparent tube. It can be tailored to output a ...

Our design approach combines 3D printable plastic structures with commodity optical sensors and standard Arduino-style microcontrollers. The general sensor configuration, including type and number of ...

Before diving into the details of sensor and actuator hardware design, you need to understand some basic concepts and terminology. A sensor is a device that converts a physical quantity, such as ...

We present tested example designs for sensors of different complexity, from a basic one-dimensional deflecting beam to six-axis sensors with custom shapes. We summarize the basic sensor layout ...

This repository holds the Arduino library, KiCAD PCB design files, gerber production files, BOM, and assembly instructions for the open-source computer mouse goodie bag item from the 2018 OSHWA Summit ...
