Looking Skeleton


Well Ii got a chance to get the microcontroller work and servo mounting done today. Here are 2 videos of the test I did and of the complete skeleton. All I have to do now is corps him up and make a slight adjustment to the servo mount.

Bell ringer update


Well while testing the bell ringer, my neighbor made a comment. He said “you know what would be funny? If there was a muffled voice screaming for help coming from the grave” I looked at him with my evil genius face and said “I hate you, now i have to make the grave scream for help”.


So, here is a test video i did to see how the audio i created was going to sound in a box.

Here is a practice test of the bell ringer before it gets buried. Since making this video i have changed the timing on the string pull.

Laser Trip Wires


So for 2 years now I have been wanting to make a Laser Trip Wire around our front yard to protect our props. Normally we have just headstones out till Halloween day when everything gets set up but none the less I still want to TRY to protect them.

Here is a video of a concept using a cheap laser pointer, an Arduino and a photocell. Now this is not my design or my code. There are plenty of how to’s on YouTube and Instructables. I do however plan to adapt the idea.

My plan is to have it set uip with a relay board and when the laser is tripped it will turn on a bedroom light and buzz real loud to wake our butts up. I am also thinking about adding a hidden loud speaker and a wave-shield to play the sound of a shotgun pumping a round onto the chamber. Not only will it scare them off but I’m sure they will leave something behind too.

This also has other uses. Such as instead of using motion triggers for animated props. Using the laser trip wire will react faster and will not set the prop off by accident do to false motion.

I will post more information and updates as I refine it. Let me know what you think…


I did some more work on it and added the shotgun sound
