Had a complete blast, won 1st price!
I will not give the details of the body construction as Dannyeurena did a pretty good job explaining that part.
My design is more for the voice talking mode and control mod part of it which adds another level of complexity.
Details of mods:
-Attached and glued a complete sub notebook computer in Prime's back (LCD screen was already broken)
-Added a Arduino controller board (10$ on ebay)
-Added 5 N/O toggle switches in left hockey glove hand to controls Pre-recorded Mp3 playbacks via an Arduino Nano v3.
-Computer sound passing thru an 200w Amplifier
-Added a hidden dynamic vocoder , this is for live Robot voice
see --> http://www.youtube.com/watch?v=9fX7cLwIuFI
NOTE: This required 12 AC as portable source.
-For the full light effets :
Added a 3 layer blue strips VU meter in mouth piece on both sides connected to 3 Arduino's digital output pins
(had to add 3 transistors as the power level were too low and 12v was needed )
Red led chasers above windshield (15$ on ebay)
Side legs white leds strip
Side back white leds strip
4 front painted flashlights (1$ each at the dollar store)
Here it is the overview connection schematic:
Sub PC Computer:
USB port <-> Arduino Nano v3 controller board <-> 6 Digital inputs switches + 3 output leds
Audio output -> Arduino Nano v3 controller board -> Analog Input 0
Left channel is for the pre-recorded playbacks
Right channel is for the live vocoder robot voice.
Software running on the Arduino has 2 roles:
-Takes in audio from PC and calculates the VU meter levels and ouputs them to 3 digital outputs (leds)
-Check the 6 digital input for On/Off state and send the correct Pre-recorded sound to plya on the PC side
* I've included the Arduino source code so people can reuse the code and upload the firmware to it.
Ive attached a video but unfortunatly, no audio is available (but I added a seperate video for the pre-recorded playback & Vocoder).
If anyone is interested in more details, I can put the required info in here.
*NOTE: Basic costume design credits all goes to Dannyeurena
