If you studying music playing, you should have a metronome. Today, electronic metronome is much more popular than mechanical metronome because the electronic metronome has several advantages. They are compact/small, reliable, cheap and very simple. Here is one example of the electronic metronome circuit : Parts: * R1 10K 1/2W …
Read MoreThis a high-side current amplifier circuit breaker. The circuit-breaker application is possible for that device because the latching-comparator output (COUT1) on the MAX4373, a high-side current-sense amplifier with reference and comparator. Here is the circuit : This circuit uses MAX4373FESA as a circuit-breaker threshold of 900mA, because its gain from sense …
Read MoreThis is a circuit which is a modification of Hartley oscillator with the addition of several components. This circuit uses a small audio transformer, type LT700. The primary of this transformer is center tapped with an impedance of 1Kohms at 1KHz and the secondary has an impedance of 8 ohms. “Chirp” characteristic of this …
Read MoreCircuit below is a very sensitive 3-transistor amplifier using a speaker transformer. This can be wound on a short length of ferrite rod as show above or 150 turns on a 10mH choke. The biasing of the middle transistor is set for 3 V supply. During idle conditions and the quiescent current is …
Read MoreCapacitance meter is one instrument that you should have in your toolbox if you are an electronics hobbyist, or if you’re a professional electronic technician. If you can’t afford to buy such instrument or you you can’t find it on your local store then here is the good news: you can build your own capacitance …
Read MoreTo extend the measurement range of an available ADC(analog to digital conveter) we can use this autoranging. If it implemented on multiplexed input, this circuit will give best result. To adjust an ADC’s full-scale range we use a system autoranging that use LTC1257 because it is appropriate for system autoranging. During …
