Mr. Microphone Hack!

Turn the classic 70's wireless toy into a modern high-tech spy device. I never picked up any chicks with it anyway. Watch the video and see the test results at the end. What I heard surprised me! This is a modified version of a similar article in "Sneaky Uses For Everyday Things".

Step 1: What you need

A vintage Mr. Microphone FM modulator. These were designed to transmit your voice over the low end of the FM band, around 88MHz. These are not easy to come by but you can find them at garage sales and occasionally on Ebay.

I did this hack back in the mid 80's. replaced the mic with a small female jack and put the board into a atari 2600 game case,along with a belt clip and replaced the batterys with a 9 volt and used it for a wireless guitar transmitter. I could walk across the street and still transmit to my upstairs apartment...Dang kids Next door thought it was a great idea and took it along with my guitar....

There are other present day forms that you can use.

"Hey good lookin! We'll be back to pick you up later." How is it possible to remember that line from the Mr Microphone commercials after all these years?

JuCo in reply to kalahariAug 20, 2008. 8:29 PM

Simpsons?

Gamernotnerd in reply to kalahariAug 9, 2008. 8:57 PM

Off of youtube?

carpespasm says: Jun 14, 2008. 5:41 AM

That poor audio-technica mic.... :( I've seen off-brand copies of the mr microphone at places like Big Lots before, so if someone's looking to do this that might be an alternative to eBay. What do you figure the run time on this would be with the button cell?

brandegor in reply to carpespasmJun 21, 2008. 4:45 AM

Just discovered that there is a "Hannah Montana" brand FM mic that can be had on ebay for 99 cents.

Jesusfreak101 in reply to brandegorAug 14, 2008. 1:50 PM

Ya, I know. You can also get those overpriced at wallmart.

Can you make an instructable to teach us how to make super cool videos like yours (editing part is the problem)? You have a great voice too.

sleepygamer says: Jun 27, 2008. 8:09 PM

Hey Kipkay, if you put this thing near a light source (maybe near a ceiling light or lamp) and gave it some small solar panels, do you think you could use them to charge a small battery to make it run indefinitely? (Or at least longer than a single battery?) Great little instructable... when I get some cash, I'm going to do pretty much all of yours! :D

i thought the sentence then take away that white thing that smells like somebody's grandmother in the video was funny.

theglove says: Jun 14, 2008. 5:34 AM

Just a thought, but would it be possible to adapt one of those ipod broadcast-over-the-radio thingies by adding a mic to it? Hmmm.

bth8 in reply to thegloveJun 19, 2008. 5:28 PM

ya, just take out the jack thing, cut the jack off the mic, strip the wires, and solder em to the thing

dracox says: Jun 16, 2008. 9:01 AM

is it ok if i use an ordinary mic?

fma321 says: Jun 14, 2008. 3:25 PM

I had to make a Mr. Microphone knock off in my Aviation tech class for practice in circuit board soldering. Try looking for one of these kits. I might hack mine or this use.
