Latest Project -- Vibe2Tone
« on: September 17, 2011, 02:02:56 am »
I often forget to turn on my cell phone's ringer when I put it on the charger and even if I do I still can't hear the phone when I'm out of the room. So I made a little device that plays an audio alert when it detects the cell phone is vibrating. I think this sort of device could be useful for the hearing impaired, too. I used a MOSFET driver to amplify the PWM audio output from the microcontroller. Feedback is welcomed!

Here's the video demonstration. It's a submission for a contest, so it's a bit over the top. Checkout the description for a link to the source code and schematic. Please give it a "Like" on youtube if you like it, because that's part of the scoring.


Here's the project I based mine on.

Dear Yardleydobon:

--Being hearing impaired myself, I find your project very interesting. I can hardly hear my Fluke 87 continuity beeper any more. Do you have any off the top of your head ideas for that. Also, could you please tell us what music you are using, it is very good, and funny.

I'm no expert but I'm guessing you have trouble with the higher frequencies. You could probably make a circuit that listens to your meter and outputs a louder, lower pitched tone.  Or listens to the meter and flashes a bright LED; something that would be easier to spot than a change on the meter's display with your peripheral vision. The music is four different unrestricted sound files I pulled off the internet. At first there was a fifth sound which was the communicator noise from Star Trek TOS, but I took it out because of the contest rules. It made me sad to do that because it sounded so cool.
