Weekend Project II
Aug 29th
In march i posted about a weekend project which involved controlling a small toy car using my cell phone, this is a similar one again implemented in few hours, here we are trying to play the awesome game of pong using the tilt sensor on Samsung Wave. The pong application running on Laptop is written in Qt (C++) and the application on the Phone is written using the Bada SDK.
The working is simple, the pong application running on Laptop requires phones to make a TCP connection to it. Phones just create a TCP connection to the application on PC and sends tilt sensor data to it, movement of paddles is done by the PC application based on the value it receives from the phones. It still requires better calibration and we will work on it after the exams are over (Education prevents you from doing cool things!!), there are a lot of ideas buzzing in our empty heads (according to our teachers!!) , the original idea was by Abhimanyu which we implemented.
if you cannot see the above video here and here are short demo of how it works.
PS – code and proper working for the previous and this weekend project will be posted soon!
Weekend Project
Mar 11th
In Dec 2009 at foss.in at the maemo stall i saw a guy control a small toy car through accelerometer on his N900, i thought of replicating that but it just remained in my mind, so last Saturday i finally decided to implement it and went straight to a toy store and bought a toy RF car, one hour of hacking and i was able to control the small car through by phone (Nokia E61i) here is the video of it working.
the concept is simple, i send commands through my phone over wifi to my laptop which controls the car remote, controlling a toy car remote is very easy with a Parallel port and few transistors but laptops don’t have parallel ports, so i used a micro-controller in between to sort that out, so now micro controller controls the car remote by acting on signals received over UART from laptop.
the working is Phone —(WiFi)—>Laptop —(USB/UART)—> Micro controller —(Relays)—> Car Remote —(RF)—> Toy Car
will post details with code sometime later
