Hello!
I have already blogged about this on the CA community...
Me, and my colleagues are working on the Sun SPOT technology
which in itself is mind-blowing! We are planning to implement a
Wireless Controlled System using the Sunspot device and Mobile phones.
Here I will give a brief idea of the project.
Basic Principle
Basically we will have a mobile phone connected to a DTMF decoder IC
along with some hardware circuit. This mobile phone will be on Auto
Answer. The circuit has 4 digital output pins. These signals will be
given to the 4 general purpose IO pins of Sun SPOT.
Now a mobile (situated in any part of the world) will call the host
mobile and once the two are in connection, the signals at the IO pins
will vary according to the Key pressed by the calling mobile. Now, we
have 12 keys in standard mobile, so we will have 12 different signals
going in to the Sun SPOT (Logically - 16 as we have 4 O/P lines).
The Sun Spot will do different jobs according to the key pressed by the
calling mobile. We plan to control remote sun spots that will
communicate with the connected sunspot according to the keys pressed.
So we can have a complete control system that can be monitored and
controlled from any part of the world.
Hardware
1. MT8870 dtmf decoder ic
2. 100k resitor 2pc.
3. 300k resistor 1pc.
4. 3.57945Mhz crystal oscillator
5. 0.1 uf capacitor 2pc.
6. 4 LED
7. connecting wires....
Software
Currently I have made a sample demo SunSpot application that continously listens to the IO pins and whenever there is any change in the input signal, a different thread is launched and a job corresponding to the input signal is launched. For now, I am just glowing the Leds of Sun Spot in different patterns.
The complete tutorial for the application can be seen here. (Note that we will be uploading whatever code and tutorials we accomplish on the wiki created as per the link)
Current Status
Both the preliminary Hardware and the basic software is ready and tested.
To be Implemented
1, We need to implement a password mechanism for a system, such that the system will work only after certain code is supplied at the start.
2. Currently we are thinking of controlling simple things like controlling devices using remote SPOTs (From anywhere in the world.)
3. We are also thinking on a way in which we can send some signals back to the calling mobile. This can be used to send useful information.
The implementation ideas for the project seem to be boundless, and any new ideas suggestions are welcome!!
Note: Special thanks to Abhishek Hisaria
