Hi, I want to make a firework detonator using a dollar store timer, so I need to amplify 20mV to 6-9V to ignite an 'estes model rocket igniter'. How could I do this? I know next to nothing about electonics
 
Where is your 20mV coming from? Is it a signal, or a power source?

What other voltages do you have available?

If 20mV is your only power source, then there just is no practical way to get enough energy to fire the igniter.
 
The timer uses an LR41 battery but the wires to the buzzer only have like 20mV apparently and that's what I'm connecting the igniter to
 
How have you measured your 20mV from the buzzer ? 20mV through a buzzer will be pretty much inaudable.

You also need a circuit that ignores any beeps that come from pressing the buzzer buttons or you'll fry yourself.
 
This thread should be closed.
We do not want terrorists to do this, do we?

That's just what the guy said in the video I posted up there ^^^

And yeah I wouldn't connect everything until I started the countdown
