In this circuit, the Elektor ATM18 [1] is in charge of communications and represents the master unit, while the DS18S20 sensors are the slave units. The DS18S20s respond to the orders from t... Read more
If you’re short of inputs on your amplifier, but it has an input for a magnetic pickup with RIAA correction, this very simple project will et you convert this into a high-level linear input,... Read more
A simple way of measuring the amplitude and phase difference between two high-frequency signals is provided by the AD8302 from Analog Devices (www.analog.com). The two input signals A and B... Read more
This tester is intended to quickly check whether a transistor is functional or not and possibly also select two or more transistors with (approximately) equal gains. This is about the simple... Read more
A temperature measurement system with up to eight distributed temperature sensors can be realized using only a single signaling lead. This objective is supported by the Maxim MAX6575 tempera... Read more
ICs for measuring currents usually employ external sense resistors with values of a few tens of milliohms. Not only are such resistors difficult to obtain, the circuit board layout can have... Read more
From the feedback from our readers, we have learned that the measurement of currents in the positive lead of a power supply is often fraught with practical difficulties. The circuit shown he... Read more
In the form of the LT1618, Linear Technology (www.lineartech.com) has made available a step-up switching regulator with a current limit mechanism. This makes it easy to protect an otherwise... Read more
It frequently happens that you have an application in which you want to measure the temperature of a circuit or the outside world. This can be easily achieved using additional components in... Read more
Contact bounce is an age-old problem with all types of pushbutton switches and keypads that are connected to digital components. The measures that are used to deal with the repeated closing... Read more
