@Richard, I thought that DJ used the "on-board sound card" of his Wall-E... I did not realize that he used external mp3 files..!

Nope, I am pretty sure he used wav or mp3 files. Wouldn't be an easy task getting the onboard sound card to spit out appropriate sounds when required... So much simpler to use wav or mp3 files through ARC...

@Richard, thank you very much! Now I must found all the sounds... I only find the classic "wwwwwalleeeeee"... I love the sound that DJ's wall-e play when the orange ball disappear!

What Rich said..... V4 with its on board speaker will make projects like wall-e even easier.... Won't even need a mp3 trigger board...

yo

@sparkino yea I have the v3 and a sparkfun mp3 trigger....downloaded a ton of wall-e sounds, plus a bunch of random audio clips too. because in the movie he would reply by playing an old tv audio clip

you can keep all the original functions of the wall-e and add many more, by removing all the original components and adding in the v4 or v3, in the software you can -add voice recognition -automated movement -specific motions (dancing, reactions to certain phrases)

but remember the microphone that is picking up the commands is on your pc/tablet/phone, not on the robot itself. you can add microphones to the robot itself, but this is only useful to make the wall-e turn towards the sound of a voice (using an ADC voltage reader thing) giving the impression he turns to see you when you speak. but the commands or voice recognition must be picked up by a microphone on the pc. (for v3 that is)

@tony1952 as far as my mini wall-e the hand rotation was pretty easy I think I posted a bunch of detailed pics on the build....I think my thread is called "pics of progress..." not sure.

originally the hand would "pump" in and out of the arm. but I noticed with so much animation in the eyes, neck and body, the in and out motion was kinda lost. no one noticed it. so I re worked the inside of the arms and made the hand rotate. used a micro servo I think.

the real challenge were the eyes. each eye has 2 servos in it. and 2 for the neck. I get up and down, left and right and a "twitch or tilt" motion from the eyes alone. then the neck moves up and down too. pretty slick.

one last thing, the ultimate wall-e has the ability to "grip" with his hand. so now im sure I will be able to add

-horizontal arm movement -vertical arm movement -hand rotation -hand gripping motion

in each arm. pretty slick right?

pics of mp3 trigger added to my wall-e

thanks @hoolagen1 I found that " Pics Of Progress" thread: https://synthiam.com/Community/Questions/678 There are lots of very detailed pics of the head/neck mechanisms but nothing on the arms. You do however mention that you used the arms from the Limited Edition Wall-E because they were "thicker than u command wall-e and fit mini servos for hand rotation" I don't have a spare one of these lying around plus I can't even pull apart the arms of my U-Command Wall-E, so I'll just stick to vertical arm movement for my Wall-E. Good luck on adding that hand gripping motion. That will be a sight to behold!

@hoolagen1, thanks! Where I can find some interesting audio clips? Please, forgive my curiosity, but I have a question: you said "you can add microphones to the robot itself, but this is only useful to make the wall-e turn towards the sound of a voice (using an ADC voltage reader thing) giving the impression he turns to see you when you speak". How can I realize this? Have you some link where is explained how to use an ADC voltage reader for this purpose?
