New for my 2014 Halloween display.... I added an old plastic skeleton we already had... to a kids bicycle I sort of stumbled upon. Since the two went together easy enough I decide to add something
extra to the setup. I first I thought about spinning the tires, or making the legs move by spinning the crank. But then I remembered I have a bicycle horn as well.
How to add the horm sound to the horm was simple. There are so MANY ways to do that part. I could have just downloaded a wav file to my HA PC and played it in any number of software products (like my BVC) and trigger the sound by an X10 command. I could have used a remote, or motion detector, pressure mat.... so many options.
I recorded the horn sound on an old MP3 player... and could have just looped that through any amplified speaker set-up.
But I also had that old RF remote "rock" speaker (seen behind the bicycle by the house in the video). So I recorded the sound of the horn using the video function of my old D-Pad. And send that headphone jack audio to the outside speaker. I decided to not automate the sound so much as watch the area via my security camera and trigger the horn manually..... just as treaters pass the bike.
See and hear the video on YouTube.
