body contact button?

[iwantomakenoise]

hi

I have been having some trouble. I bought a walkie talkie and started to play with it made some ok sounds out of it but the best sound i can manage is when i touch my finger directly on the board in certain places. I want to reattach the case to the walkie talkie so i want away of attaching something that will act similar to me touching the board? i have heard about body contact button but not sure on the full details?

anyone help

cheers

Hello
a body contact is nothing more than a simple metal plate. It can be a screw/bolt/nut or whatever made of steel, copper, gold, ....

If you want it comfortable you can insert  a switch to enable/disable the bodycontact and a potentiometer to adjust the sensitivity (for sweaty/dry fingers

mmmh in case I misunderstood your question you can "emulate" a body contact with this circuit...

hi

thank you i might try that but at the moment I have found out away of doing it. i simply and my i say effectively just attached several cables to the points and using my finger change the sound.

but i might try it your way
