Portable 230V lamp flasher circuit electronic
The circuit is completely transistorised and battery-powered. The free-running oscillator circuit is realised working with two low-power, low-noise transistors T1 and T2. One of these two transistors is constantly conducting, whilst the other is blocking. Because of normal charging and discharging of capacitors C1 and C2, both the transistors alternate between conduction and non-conduction states.
