    DIY Solar Tracker System The solar panels are operating at optimal parameters when they are at the perfect right angle to the sun. Unfortunately this is accomplished only if solar panels are rotated by the sun. This is the purpose of this diy solar tracker system or if you have an Arduino board then you can build this one that uses a servo. The solar...
    Greenhouse Heater Temperature Control Standard resistance heaters used for space heaters sometimes have thermostats, but these are not adjustable to the low temperature settings required for winter greens. Instead of purchasing a high end programmable temperature controller, I fabricated this greenhouse heater temperature control project circuit. It cycles an...
    LM2902, LM124, LM224, LM324 Datasheet The LM2902, LM124, LM224, LM324 series consists of four independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current...
    Diode Digital Thermometer Circuit This digital thermometer circuit diagram uses a common 1N4148 diode as the temperature sensor. The temperature coefficient of the diode, -2 mV/°C is exploited for this application to create an accurate electronic thermometer. To display the measured temperature, a digital multimeter is used and so we can measure...
    Remote Audio Level Indicator Circuit The normal level-indicator circuits which are available in the market require connections to be made to the output of the player, which may not be easily accessible. The audio level indicator circuit described here removes this restriction as it may be placed close to the player’s speakers and yet the desired effect can be...
