Easily measure inductance using Arduino

Moser from ReiBot has developed a simple project for using an Arduino along with an LM399 and several discrete components to measure inductance. He says: So you need to make or measure an inductor, but you don’t have an oscilloscope or signal generator? Measuring inductance with a handful of cheap common parts is certainly possible. […]

Attiny2313 based LAN cable tester

Vasilis Stergiopoulos has built a RJ45 LAN cable tester. The circuit was originally designed to use a 555 and 4017 IC, but Vasilis has published the schematic and source code in assembly for using the Attiny2313 instead. The Attiny2313 produces successive outputs at port D, where the LAN-cable is connected. If a straight cable is […]
