How to Calculate Solar Panel, Inverter, Battery Parameters
In this post I have explained through calculations how to select and interface the solar panel, inverter and charger controller combinations correctly, for acquiring the most optimal results from the set up. Calculating Solar Panel, Inverter and Battery Charger Specifications For the sake of convenience, let’s believe you possess a a 100 watt appliance or […]
Car Speed Limit Warning Indicator Circuit
In the following post I have explained a simple yet useful car speed limit warning indicator circuit which can be used in vehicles for getting an instant indication of a possible over speed limit conditions. The idea was requested by Mr. Abu-Hafss. Technical Specifications: Shall appreciate, if you could design a circuit to warn with […]
High Current 209A, 75V MOSFET IRFP2907 Datasheet
In this post I have explained the main features datasheet of high current N-Channel mosfet IRFP2907 which is rated to handle up to a staggering 209 amps of continuous current at a reasonably massive 75 volts. High Current Specs With the advent of mosfets, switching huge power through compact packages has become particularly feasible. Take […]
Low Battery Indicator Circuit Using Two Transistors Only
In the following post I have explained a simple low battery indicator circuit by using just two inexpensive NPN transistors. The main feature of this circuit is its very low stand by current consumption. The Circuit Concept We have so far seen how to make a low battery indicator circuits using a 741 IC and […]
Long Range Transmitter Circuit – 2 to 5 Km Range
The proposed long range transmitter circuit really is very steady, harmonic free design which you can use with standard fm frequencies between 88 and 108 MHz. Technical Specifications of the Transmitter This will likely encompass 5km spectrum (long range). It includes an extremely consistent oscillator for the reason that you employ LM7809 stabilizer that is […]
