Crankenstein's Castle

Here's a video of·our BS-1 animatronics art piece. I just did·the electronics, and we had a big team·working on the whole thing. There's a lot going on, so I used one master BS-1 Project board and two slaves to sync everything together. The "tachometer" needle is a servo, which is sync'ed to the engine rev soundtrack. The jumping motorcycle and small moving robot arm·both use·simple motor modules. Lots of synchronized LEDs (spark plugs, search lights, etc) and some HV red & blue glow tube on the robot arm. The MP3 player was·controlled using several Stamp-controlled reed relays.

Cool. Was each sound effect a separate audio cue or did you just start the MP3 player and time your actions accordingly?
Do you remember the type/brand of reed relay that you used?

There were two different custom tracks created by our sound lab wizards. Track one was a very low volume, continuous background track that looped 24/7. No animatronics here. When triggered via pushbutton or IR remote, the stamp advanced the MP3 player (via Radio Shack 5V reed relay) to the second track, which had louder main sounds all laid out in sequence. I just tailored PAUSE statements in the program to trigger the various LEDs and motors to sync with the sounds. The very last pause command (after all the animatronics had done their thing) advanced the MP3 player again to the next track (really back the the beginning). I used another Stamp-controlled relay just to turn on the MP3 player at initial power-up.

Hi erco,

My project is working really great. My only problem is I can’t get enough of an audio level from the headphone out. I’m using a Bose Wave (with the aux input) and it’s just not putting out enough volume. I guess my question is – what did you do?


Thanks,
Andy
