A simple motorcycle battery over discharge protector circuit is explained in the following post. The circuit will prevent the battery from over-discharging by the motorcycle headlamp whenever the mo-bike alternator is not enabled or is idling in the neutral mode in which case the battery is normally subjected to excess loads via the headlamp bulb. […]

5 Useful Motor Dry Run Protector Circuits Explained
The 5 simple dry run protector circuits presented here shows simple methods by which insufficient water conditions inside an underground tank can be sensed without introducing probes inside the underground tank, and thus preventing any possibility of motor dry running. The circuit also incorporates an overhead water overflow control feature. The idea was requested by […]
Simple Triac Timer Circuit
Here’s a simple triac timer circuit which can be used for switching ON a particular device after a predetermined time, set through the given pot or the variable resistor. The shown circuit diagram of a simple triac timer can be understood by referring to the following explanation: How it Works The left hand side section […]
Low Pass Filter Circuit for Subwoofer
In this post I have explained a simple low pass filter circuit which can be used in conjunction with subwoofer amplifiers for acquiring extreme cuts or bass in the frequency range 30 and 200Hz, which is adjustable. How it Works Several low pass filter circuits for subwoofer application are presented all over the net however […]
IC 555 Automatic Emergency Light Circuit
The discussed 2 simple IC 555 based emergency lamp system employs just a single IC 555 and yet is able to switch more than 20 LEDs directly, it will illuminate the LEDs only during the absence of mains power and ambient light. 1) Using IC 555 as a Comparator The proposed circuit is not only […]
How Buck-Boost Circuits Work
We all have heard a lot about buck and boost circuits and know that basically these circuits are used in SMPS designs for stepping up or stepping down a given voltage at the input. The interesting thing about this technology is that it allows the above functions with negligible heat generation which results in a […]
