Ideas for project. Motion activated playback of random recorded audio?

wabbit

Hi all,

I'm new to all this.

I just completed my first project (will post it soon) hint: turret gun with scanning ping sensor.

Here's the idea for the next project. What supplies do you think I need (voice chips, speakers, audio amplifiers etc) Try to keep it affordable?

A guy walks into a bathroom. There is a mannequin in the bathroom. Once the mannequin "detects" the guy she saids random "comments" P.

I have a basic stamp 2 to operate the sensors and trigger the audio. What do I need for the audio portion. I would like to be able to pre-record wav files on the computer then download them. I would like to have 5-10 short sound bytes that will playback in a random order.
I am thinking of using a passive IR sensor.

How would you approach this project if you were a beginner?



Thanks
wabbit

Quadravox (www.quadravox.com) has a module (QV606) that will play MP3 "files" from a flash memory. It will connect directly to a group of Stamp pins. It has an amplifier on the module, so you'd only need a speaker and the PIR sensor. Another option is the VMusic2 from Vinculum (www.vinculum.com/prd_vmusic1.html) which plays regular MP3 files from a USB flash drive. You'd need some kind of amplifier with this. You could just use an amplified speaker like those used with computers or you could build a DIY amplifier kit like this one I've used: www.kitsrus.com/pdf/k47.pdf. You'd need two for stereo.

The details (wiring and programming) would depend on which module you choose, but both are straightforward to use with a Stamp.

How long ago did you get the VMUSIC2?· The FTDI webshop states they're not available (and, I'll note,·haven't been for a while),·but with a then-listed price of £20 (???, now appx $40) I can see why.· Pretty cool little gizmo, and it's not a kit.· I got a Daisy MP3, and it's a kit, and it uses a SD-card; having a nice module that accepts a USB memory stick would be pretty cool.

Anyone tried the MP3 mini-board that futurlec.com offers?

It seems to be pretty interesting... especially when combined with their SD board.

I have no idea how compatible that setup would be with stamps though... I'm just a noob [noparse]:)[/noparse]

For audio, I've worked with both:

The uMP3 Playback Module from Rogue Robotics

and

The V-Stamp Module from RC Systems

I like both of these products very much and found them easy to work with.· The V-Stamp will give you text to speech synthesis in addition to audio playback.

so i'm liking the qv606 module mainly because of price and built in amp. It seems like some of the other modules are a bit overkill for my needs.

Do I need to get the programmer from them as well or can this be "cobbled" together reasonbly easy?

So how does interfacing with the BS2 work with this module?

Thanks·for all the help. Its nice to have a place for newbies like me to learn.
