I was always fascinated about software and hardware interaction. But with my limited knowledge in electronics, I kept the hardware part aside and was working only in software. After having some hands on experience with my first Raspberry Pi, I decided to build a toy for my son. I purchased my second pi and some other components and this is what I built. Yes it looks ugly but worth playing with it :).
Last couple of days I was refreshing my basic electronic skills and virtually designing the software and hardware for the device. You can find so many similar RaspPi based toys and I am adding one more to it.
Yesterday evening I got the last piece of the puzzle, the rechargeable battery. After that I spent the next 5 hrs to code the application running in the vehicle and the Remote control app for my Android tab, remote control app is based on the Acclerometer of the device. To control the toy I decided to use WiFi and use my Android tab as a steering wheel. I will go more details into the software part in a different post.

Rest of the post will go through the components used in the tracker and how to acquire it. If you are in Bangalore then you can get all these items from OM Electronics in SP road or you can buy online. I bought it from OM Electronics.
