Fbi sleeve microphone frankensteined in walkie talkie Answered

Drumroll please...it's the world's (or at least instructable's) longest forum post! :D I want to solder a microphone (I ripped it out of an old telephone headset) to a walkie talkie's board in such a way that I can talk into that and have the walkie talkie pick up that instead of the input from the preexisting mike...I figured I would have to use the same old push to talk button, but I would sure like to be able to press a button near the mike to talk. I want to thread the mike up my arm, like a secret agent! The Where would I solder the microphone wires? Do I have to worry about burning/shortcircuiting my microphone or the walkie talkie? Is there any way to attach a talk button so it runs down my arm as well? Thanks!

Why the Calvin and Hobbes of course! :-)

:-) The reason I was hedging so much is because I have "over heated" a number of "crystal" and piezo-electric mics in the past trying to solder them. Dielectric elements can be a little funny too.

Oh, ok. Well, thanks for not telling me to recklessly go on then...Oh, if you're interested, I figured out how to do this project without soldering anything. Not enough for an 'ible, though.

Well that's good. Even if it isn't enough for an ible, would you like to share what you did ?

Well, I noticed that the walkie talkies have a spot to plug in a microphone headset, so I just took a computer microphone, removed the plastic, and threaded that up my arm. Then, I took an earbud that is single because one broke and put it on. Then just plug into a Y-splitter and set the walkie talkies on vox.

Well it was meant. You solved the problem by thinking "outside the box" or as they say, "laterally". Lateral thinking is not taught in schools, only top down logical thinking. So it is definitely a plus.

electret is the proper name for what I called a dielectric....

Wow, there is a lot in there that simply "depends" (no, not the adult diaper, that Depends). Let me pick out just a few: worry about burning/shorting the existing mic ? Always worry about shorting anything, but burning, well if it is an older "crystal" mic, very much so. They don't like heat. An even older carbon mic might even be worse. Some electret mics are pretty sensitive to heat too. Etc.

Haha, Depends! :D Thanks for replying. How do I figure out how much current the mike needs?

Sorry I wasn't more specific. Again, do you know what kind if mic it is ? I wouldn't know off the top of my head the best way to test this, especially if it is a crystal mic (too much current will perforate the crystal and it will become useless). If you can come up with that, myself or someone else could go from there. How old is this headset? Is it old because it is discarded, or old because it is possibly 10+ years old?

Old because it dosen't work anymore, but I just found the package to one I had in a box that is exactly like it!!! Hooray! It lists everything I need! Let's do the happy dance!
