Homemade electronic telegraph

can the capacitor be home made?

@mbro96 yes! :) But if the capacitance is too low, the sound's frequency would be too high to be eard.

I like the sound. Has a little attack.

@jeriellsworth thank you! I wanted a higher tone, but i didn't have the right capacitor value.
