I have posted the how-to for the wallbreaker mechnism. It took way longer than I thought it would, but I wanted to do it right.
Wallbreaker How To
I have done my best getting everything right, but if you find problems or have questions please post them here.
Now I can get onto my next project. I will rebuild either the leer ghost or the ghost reader for the next hauntproject contest. I cannot win, but it will still be fun to enter. I will update here with my progress.
