rf+tag+coil+and+capacitor

With the circuit shown here you can create high frequency electromagnetic waves with very high output power. Possible applications are experiments with wireless power transmission, RFID Transponder, tesla coils and the like. Dependent on the coil, capacitor and cooling of the transistors output power in the range of 20W and more can be obtained. At [...]

A DC-DC converter or another name known as buck regulator or switching regulator (because the input voltage can be either above or below the desired voltage output), provides stable regulated output voltage to supply electronic circuits. LM2576 converter circuits perform same function as the commonly known voltage regulator LM7805 from National Semiconductor. The 7805 voltage [...]
