Billy Cart Report 

My Billy Cart Blueprint

My machine is a mosquito killer racket. I saw the parts inside the mosquito killer racket. I opened the mosquito killer by using a screw dvier. There are many cables inside it.  

Also, I can see the battery holder inside it. I also saw the energy changer that could change negative power to positive power. There was a chip inside the mosquito killer racket.


I also open the clock by using a screw driver. And I saw a bell on the clock. I saw a lever that is used to hit the bell. And I saw may screws inside it. I also saw many other things.
