Inverter circuit on basic of really taking a series of mosquito racket, a racket in which these mosquitoes require only a low voltage. With only 3 Volts course of this series has been able to work. Circuit is raising the voltage by a transformer that can be made yourself with the need of copper wire and ferrite rods. How to making a transformer like that here , but this circuit requires a step-up transformer that are larger and require a lot of coils. This transformer is controlled by a transistor semiconductor 24D506 in this series. To output issued until 1KV or more but issued is very low amperage. This circuit can also be used in fluorescent lamps 10W maximum . When used in fluorescent lamps add another capacitor to the voltage for provoke can turn on the lights.

Build a Power Supply Variable 1.3V - 12.2V 1A Circuit Diagram . In this circuit R2 to set the output voltage. The maximum current is determined by R3, over-current protection circuit inside the LM723 to detect the voltage on R3, if it reaches 0.65 V, the voltage output will be off her. So the current through R3 can not exceed 0.65 / R3 although output short-circuit in his. Power Supply Variable 1.3V - 12.2V 1A Circuit Diagram C3 and C4 are ceramic capacitors, as much as possible directly soldered to the PCB, this is because the LM723 is prone to oscillation that is not cool. LM723 works with 9.5V input voltage to 40 V DC and the LM723 can generate its own current of 150mA when the output voltage is not more than 6-7V under input voltage. Specifications: Output (value estimated): Vmin = (R4 + R5) / (R5 * 1.3) Vmax = (7.15 / R5) * (R4 + R5) Imax = 0.65/R3 Max. Power on R3: 0.42/R3 Min. DC Input Voltage (pin 12 to pin 7): Vmax + 5 Parts List: B1 40V/2.5A C1 2200uF (3300uF even better) C2 ...
