Voice changer megaphone

[Spann]

Hey guys...

So, I finally managed to finish my first project, a voice changer megaphone (Blogged in the link below). However, I have another board for one upstairs that I would like to build a feedback loop into - do you think it would be as simple as sticking a toggle across the speaker output and the input?

I'm going to be blogging my misadventures here as well:

hey i'm not sure if you're still working on this project since this post was so long ago but here is pete from casperelectronics schematics for that same megaphone i believe.

he incorporates input, output, feedback loop, pitch (works with feedback) and pitch body contacts.

he also has a wet/dry mod for volume and a schematic for volume increase.

hope this helps!

Hey,

I've seen that schematic, but it's actually a different unit to the one I've got. Rather than having the four switches, mine's onl got one three way one.

I'm actually working on another one which I'll hopefully finish in the morning with a 555 input and some other jazz.

I've seen a few different board for these things, and they all seem to be very slightly different - That wet/dry mod does look tasty though.
