The servomotor driver and tester unit might excite two types of electronic enthusiasts namely model vehicle owners and robotic system builders. As shown in the diagram, the circuit equips a […]
9V Power Supply Circuit using SCR with Auto Switch OFF
The low loss power supply circuit explained here employs an SCR that chooses taps on the secondary of the transformer based on the load current. Thus it helps to dissipate […]
Very Low Frequency (VLF) Converter Circuit
The circuit explained below can be used for detecting and converting the very low radio frequencies or VLF in the atmosphere to audible sound. A huge number of general-coverage shortwave […]
Antenna Booster Amplifier Circuits
In this post we discuss a couple of useful RF antenna signal booster circuits, which can be used with any RF receiver circuit to amplify incoming signals to higher levels, […]
7 watt to 10 watt Amplifier Circuit using IC LM383
This proposed 7 watt amplifier circuit is like an efficient audio booster. It is easy to construct and also works like a charm when amplifying audio signals or increasing the […]
Audio Squelch Circuit
In telecommunication devices, the squelch circuit is introduced in order to enable the suppression of the audio (or video) output of a receiver whenever a low or weak signal input is detected. This circuit attenuates the background noise that […]
