Earlier tonight my daughters and I created the two LED Ghosties that I have been working on for about a week.(one for each daughter). I was planning on making three, right now I am kind of glad I only made two. I thought I did enough pre staging of the parts but nope took a bit of time.
The first part in building of the Ghosties are in the previous posts:
Evil Mad Scientist (Dark Detecting LED Pumpkin)
First circuit build
Second circuit setup
Now that you are caught up on the initial stages here is the link from EvilMadScientist about the LED Ghosties.
