Now that I have finished B.O.B., my get your feet wet bot, I have begun my next hack. This next robot will bridge the gap between Bob and my ultimate big robot. I am starting with a remote controlled B9 toy from Trendmasters. It was very limited in what it did, and the drive section was pathetic, but it was B9!
Before Pics:
Note: the front "lights" in the chest plate is actually just a decal.Here is what B9 looks like now:
I have mounted clear LEDs in the appropriate colors in the chest at the bottom of the decal and have a flashing circuit that will blink them in the combination as seen on the series. Where the two large round circles are (white domes on the big guy) I will have my ping sensor. I have mounted pager motors in the antenna housings to turn the "sensors" as seen in the TV version. I have mounted red El Wire to his voice plate to emulate the original as well. I have also mounted a series of blinking LEDs to the "brain" section in the bubble.
Next is to work on the rotation of the bubble and torso, articulate the arms and claws, and make a real functioning tread section. For the tread section I am adapting the base from my RAD robot. I will keep you posted with pics as I proceed.
Thanks,
Bret

plastic - Heng Long is the brand.
Unless you get lucky and it looks perfect dropping the torso on the tank use the rad. Rad base is rubber so it doesn't get hung on carpet
So I used the MP3 set up found by Louis T - very inexpensive and to be honest, I had trouble finding 40 phrases I really wanted to use, so it is perfect. First the MP3 with sound card (that I can change the clips if I want to)

Then the amplifier - very cheap and allows to me to adjust volume for my application.-634857208212500000.jpg)
All tied together with a cool speaker I got from Josh.-634857208786718750.jpg)
It all works perfect. My camera phone does not do the sound justice, at half volume it is really loud.I tried tying my LED array (for voice lights) directly to the output from the amp and it worked great. However, the amp has a constant power on the output when on so there was a slight glow to all of the LEDs when he was not talking. The output from the MP3 player does not provide enough voltage to light up all of the LEDs so it was very dim when he spoke. I do have a 1 watt op amp that I think I will take a feed from the MP3 and use this to drive my LEDs. We'll see. I have tried wiring LEDs directly to the speaker before and it works very well, just not with the number of LEDs I have to use for this, and the amplifier needed for this speaker.
bret.tallent, robot cool, good idea to connect the LEDs to the output of the amplifier, never entered my mind, I have seen your mp3 trigger is not selling in spakfun, could pass me a link of where you bought it, you greatly appreciate it, Greetings
Thanks R2 - I got mine from MDFLY Electronics before they ran out.
linky
it seems a lot of MP3 are discontinued,better to find one thats a new design or buy many of
There is a new module at MDFLY that uses the mini TF card and allows for 99 Mp3s. It is $20 so I ordered one and will try that out.
