Hi everyone
I have a piezo humidifier disk that work with 24v, 1.7mhz
Because i didn't have a 24v supply i decided to use a desktop pc power supply, as you know we can have a 24v dc with using the blue and yellow wires of pc power
Blue wire =-12
Black wire =gnd
Yellow wire= +12
To achive 1.7 mhz i use 555 astable ic as digram shows and a NPN transistor number 13005
Every things is. Correct but i don't know why my humidifier not working
