I think the high tech involved in Halloween home haunting is interesting. I know from my point of view, I like to set some goals each year and see what I can hit. I actually have a pop up working for this year and I'm trying to get the radio shack sound card hack done. I'd say on a scale of 1 to 10, I feel that I'm at about a 5 and sounds like you are at the 8 or 9 level.
Incorporating electronics can get really frustrating because all you need to do is one thing wrong and the whole prop is useless.
I'm in no rush and enjoy building on what I've learned. Gives me something to look forward to next year.
However, if it wasn't for forums like this, I'd be in the stone age.
