Metal Melting High Voltage Flyback Transformer With NE555 Driver



About: I just love electronics! Visit my youtube channel

There i built driver using NE555 for flyback transformer. Frequency is above 20khz, because i can't hear it squealing. In video you can hear it squealing because before i soldered second transistor in board it were really squealing loudly. But after i made PCB for it, it's quiet. I'm powering i with 17V and it draws not more than 5A.
