I had a problem. I never slept well at night because my mind was always racing with ideas. Every morning at 6am it was time to get up and get in the car, but I wasn't waking up. My mother would yell and call me repeatedly and I would stay asleep. My mother's solution was to remove the lock of my bedroom door so she could enter in the morning and yank me out of bed. But I was the youngest of nine and I wanted my lock.
I had this "RC Car"... not radio RC, but with a cable going to the controller. It was broken, would not turn anymore. So I opened it and play with connecting the cables directly to the DC Motor to make it turn. I figured out how it worked, and took it off the car and I tied a string to it, with a weight at the end... the string and the weight would rotate... hmm.... I then attached it to the wall and screwed a soda can... turned it on and "bam bam bam bam bam".... then I ran some cables to the other side of the wall, installed a switch and called my mom:
Me - "Mom, you don't have to take my door lock off. This is what you gonna do... in the mornings, you press this button, it will turn that motor, rotating that string, slamming that little rock against that soda can... look"
BAM BAM BAM BAM BAM BAM
Mom - "Wow... that will sure wake you up"
Interesting note... I was 7 years old.
