Why my kids would love a motion activated sprinkler. :)

An electric fence found on the farm works nicely. Non-leathal and kids are only
curious about it
ONCE!! If you build a PIC based version let me know. I'll work on it with you. I
 need to keep mice
out of my MG.

I was in a friends basement as he was searching for something or other. He came
across an old
style 24 hr format mechanical digital clock. He pulled the clock off the shelf a
nd asked his 6
year old son if he wanted to play with it. The kid dissapeared faster than the R
oad Runner just
before the coyote was foiled by his latest scheme. Apparently, one day the boy r
eceived a 120VAC
shock while playing with it and just the sight of it scared him.
