How to Make a Solar Panel Optimizer Circuit
The proposed solar optimizer circuit can be used for getting the maximum possible output in terms of current and voltage from a solar panel, in response to the varying sun light conditions. A couple of simple yet effective solar panel optimizer charger circuit are explained in this post. The first one can be built using […]
Face Mask with UVC Disinfected Fresh Air
Face masks have so far proved to be the most effective first line of defense against all contagious epidemics and pandemics. However, the biggest discomfort with face masks is the difficulty in breathing and accessing fresh air. On the other hand, if the masks are made porous for letting fresh air in could also allowing […]
Digital Clock Activated Water Level Controller Circuit
An automatic clock time triggered water level controller circuit which responds to a real time clock input is discussed in the following article. The design also includes a water detection stage which makes sure the initialization takes place only in the presence of water in the tank or the pipe. The idea was requested by […]
How to Make Ultrasonic Remote Control Circuit
This ultrasonic remote control circuit can be used to switch and control any appliance ON/OFF through a relay in the receiver circuit. Written by: S.S. Kopparthy Using Ultrasonic Waves This circuit is a different one that uses ultrasonic sound waves whose frequency ranges from 40 KHz to 50 KHz. These waves can’t be heard by […]
Digital Thermometer Circuit – Uses a Solar Cell for Power
The articles explains a digital thermometer circuit project that works without a battery. Instead of a battery the circuit utilizes a small solar cell and operates by deriving power from the ambient light available from the surrounding light sources. This allows the circuit to be extremely compact, light weight, versatile and hassle free while measuring […]
