Finished off my Threepio last night! I'm pretty happy with it..
That OK paint looks great, but if you apply too thin it looks pebbly..and too thick it looks smooth, but it can run and takes FOREVER to dry! Seriously..weeks later if you hold a part it will leave fingerprint impressions!!
I made a video clip. The motion sensor light thing I made works decent enough..but if I leave it on when you walk up to him and wave a hand in front of his face his eyes light up..perfect. Trouble is the voice box doesnt trigger until the lights go OFF! DOH! It isn't too bad for volume. It sounds REALLY quiet in the clip cuz my camera has a crappy mic!
I have a remote controlled outlet switch...so I just press a button an a keychain and the lights go on then and the sound..so that works. That way during a movie or if he gets annoying I can turn it off. The voice box is triggered by the lights going on and off so if they aren't on he doesn't talk.
I also have a base form a C3PO dashboard driver toy. I removed the figure from it and mounted it to the top of the nearest stanchion...so you can press the button and he says 10 or so random phrases.
CRAPPY mic on camera..turn up speakers!!!!!
