A light meter is a very useful device that finds applications in hospitals, schools, factories, parking lots, passageways, and many more to measure and maintain adequate lighting levels. It is also ...

If you are just starting out in electronics, you need tools. But it is hard to build all your tools. Even though we see a lot of soldering station builds, you really ought to have a soldering iron to ...

Arduino enthusiasts and makers looking for a project to keep them busy this weekend may be interested in a new Arduino powered DIY Gauss meter that once constructed can easily provide feedback on a ...

Makers, developers, and hobbyists looking for a way to measure both voltage and current simultaneously may be interested in a new Arduino project published on the official Arduino blog. This project ...

You can use a multimeter with capacitance-measurement capability to measure the length of wire or cable to an open circuit. The capacitance of a pair of wires (or a wire to a shield) is directly ...

We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. [Udo] hit upon the idea of pulsing a laser pointer and measuring the time of the ...

Today I got a multimeter (nothing fancy, precision is +/-0.5% for DC current to tweak my lines (Antec Truecontrol).<BR><BR>Findings:<BR>- motherboard measurments are generally unreliable, for instance ...
