| The price of fuel only ever seems to go in one direction so it is important not to waste it. The use of a wideband lambda sensor to analyse...
| A rectangular wave at around 500 kHz built using a 74HC04 can be used to trigger an AVR microcontroller back into operation.
| Measuring small differences between high voltages normally calls for special ‘differential’ test probes, which do not come cheap. But you wo...
| When it is required to make a measurement at a node of an RF circuit, connecting to the circuit using a normal oscilloscope probe, even on t...
| A lambda probe (or oxygen sensor) can be found on the exhaust system of most cars running on unleaded fuel. Having reached its normal operat...
| A RF probe is a handy piece of test equipment that converts a high frequency signal to a DC voltage. In this way it is very easy to measure...
| This function generator is traditional in as far as it consists of a comparator, an integrator and a triangle/sine wave shaper. However,...
| Reliable measurement of an electrical quantity is possible only if the circuit in which the measurement is carried out is not loaded by t...
| Motorola's 68HC11 is currently one of the world's most popular microcontrollers. This article presents an emulator for this wonderful...
