This electronic fly disinfestation browser is simple and easy to make, it is used to wipe out all flies which fly to the power grid of the device. The circuit is shown in Figure 1. The whole device is supplied by the 220V electric supply after being rectified. R3, R4, R5, C1 and double-base diode form a relaxation oscillator, the output pulse signal is used to control the SCR's turning on and off. When SCR is in the off state, electric supply VD is rectified and charges for C3 by equivalent resistor R6 and L1. When VS is triggered and turned, C3 discharges rapidly by SCR and the equivalent resistor of L1. When the discharging current is over zero, the SCR cuts off automatically. This repeats the cycle, the secondary stage L2 of transformer gets a high pulse voltage, the voltage is applied to the power grid composed of many equidistant electrical wire, power grid sets bait to attractflies, and when they touch the grid, they will be electrocuted and then drop from the space, that realize the effect of automatically disinfestation.
