6-05-2014 | Atmel AVR microcontrollers are very popular, not least because of the free development tools that are available. In this E-Book (Free downlo...

1-05-2014 | This article describes how easy it can be to use a current transformer to make precise measurements of alternating currents. We use a wide v...

1-04-2014 | To calculate current we normally use a shunt to turn it into a voltage and measure the latter instead. But if we wish to measure the current...

1-01-2014 | Time-dependent voltage measurements are easy to take, with just a test probe and an oscilloscope. These days signals from DC up to a few ten...

1-01-2013 | Surely not another digital clock? Well this one is simple to build and a bit of a novelty. It strikes every quarter hour and hour, and the s...

1-01-2013 | The author’s rechargeable battery collection comprises a large number of cells of various types, ages and states. Surely he cannot be the on...

1-10-2012 | This series has demonstrated that the ever-popular AVR controllers are also useful for signal processing. In this final instalment we take a...
