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:
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

Good work! wait impatiently to see your finished project, once you have completed the robot begins a new stage with the programming and experimentation, Luck.
Thank you
Why use two voltage converters for the same 6v? Looking great im excited
There will be many instances wherein I have 7 or eight servos running at the same time as well as a bunch of lights, so I thought it might be a bit much on the amps pulled from one converter. Just to be on the safe side I used two. They are cheap enough (especially since you gave me one haha) so better safe than sorry.
So I've been playing with voice on B9. The lighting method I had come up with worked well but didn't fit well and was causing the cover plastic to crack. So I went to an LED array. It is okay for me. I tried tying the lights right to the speaker output (which has worked well for me in the past) but I guess I have too many LEDs in the array to light up. So I hooked them up to the other output of the amp but this caused a ghosting with the LEDs constantly on at low strength. Finally I decided to try a second op amp just for the lights. The MP3 trigger has two outputs, for L and R so I took one of those into the 2nd amp and put the output of that amp to the light array in the chest. It works well enough for me and gives me a lot of adjustment for both sound and lights.
What caused the ghosting to go away? Looks great!
Are you going to use speech recognition with your little guy? It's awesome being able to have a conservation with my full sized B9! The only problem is using the MP3 Trigger the mic pics up what B9 is saying and more then often he will interrupt himself with another phrase. DJ said he will work on a fix for this issue.

this is an awesome project! the work is very clean
where did you find your voltage reducers? i was wanting something like this for my project to power servos and lights.
thanks
@dschulpius I have been hearing about this LED "ghosting" effect... and people wondering how, why and more importantly how to stop it. Basically it is not so much the LED itself (aside from its sensitivity) but rather the driving circuitry allowing stray current to leak through when the LED should be in an OFF state.
I think in Bret's case, the stronger amplifier just had a stronger "hum" or background noise when there was no sound... thus causing the LED to ghost. Perhaps putting in a larger resister inline with the LED would keep the lower voltage from actually powering the LED.
@bret.tallent I really like the detail you are putting into your robot... settle only for the best
