Shark Rehab
Description
I had several plans using a DC motor, but the power was not enough in most of cases (or I couldn't find the right material to use). I ended up a project to rehabilitate /revive a broken bath toy. It is a shark who used to swim in a bath tub by winding up. It is a cheap but my son's favorite. I felt sorry for him whenever my son asked me to windup the shark because it can't swim at all.
I took the parts out and connect the parts with DC motor and added LED (for fun). The speed of moving fin was controlled by FSR, and the LED brightness was also synced with little bit of flickering.
The toy was designed to use the windup gear, so I had to take some parts out and fix the broken parts. After many trials and errors, I could fix the fin of the shark and I showed it to my son :) (He was very excited and tried to press the shark to the breadboard. However, soon he got very angry because I had to take the shark away. "It's mama's work to show in class! Sorry!"
