In an ideal scenario, a battery should have zero internal resistance. But batteries are not made perfect and the electrodes are not 100% conductive, which creates a small resistance within the battery ...

If you are a maker like me and looking for some interesting projects online, a milliohm meter is one easy and useful thing you can make. The basic principle of this circuit is based around a constant ...

RF log detector/controller AD8317 and an Arduino Nano make a compact RF Power Meter possible. The RF front-end is a 4-layer break-out-board with SMA. Based on: https ...

Capacitive sensors are widely used to measure various physical and chemical process parameters such as displacement, acceleration, thickness, force, pressure, stress, level and humidity. The measured ...

This project describes a Conductivity Shield for Arduino Uno that allows you to accurately measure the conductivity of chemical solutions. Conductivity is the ability of a material to transfer ...

While preparing our race car (a 1996 Dodge Neon decorated to look like an upside down cow) for the 2013 Chubba Cheddar LeMons Race, it became apparent we were going to need to get creative when it ...
