Raspberry Pi Forums

Hi everyone,

I'm new to this forum, and I post something because I want to work on electronic this days and had a idea with a friend tonight.

It is to build a electronic model which can do several different things. I am new to electronic, just have a Makey Makey, I work a bit on the code, but I don't know a lot.

So, for this model, I want :

> When it is on, It will have to say maybe ten differents audio samples, randomly. And It will read those samples in a frequency of 1 second to 24 hours, randomly. It's a project I do for a friend. The model will be in his house, and will say some things anytime
> When a sample is read, I want the eyes (two red leds) blinking
> Also want the arms (optionnal) and especially the jaws moving with the rythm of words
> And the final touch, the thing needs to have a switch on him. When a dude wants to hear a sample, without waiting 1 second or 24 hours, he just has to hit the switch, and the a sample is played.

So I think I need this :

> A switch to put it on
> Power supply (what voltage?)
> A manequin (I will have one soon )
> Two leds
> A raspberry pi to program all that stuff
> A speaker (will put it directy in the mouth, I think)
> Two switches
> Some pieces to make the jaws and arms move ????? Don't see what kind of piece of electronic or mecanic I can use... Someboy has an idea?



Maybe it is a bit difficult to begin with, what do you think?

All of what you want to do is simple controls of switches, leds and motors, plus some programming to put it all together. Pick one requirement and get that working, then do the next, and so on. Finally put all the pieces together; both the code and the model.

Sanitized the post a bit.

The RPi's analogue audio output is not powerful enough to drive a 'raw' loudspeaker - the round metal thing with a black paper cone you see inside a radio. You need amplification, either a separate amplifier or a speaker with its own amplifier.
