This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
A number of years ago, Sun created quite a stir at a Java One convention by passing out Java enabled rings. The iButton chip in a stainless steel can executed an early version of J2ME. I still have some of those chips around here somewhere. Bill
Thats neat too ! So why didnt the i button catch on ? This is the first time i am hearing about it.

yes guys, I want to have a Java programmed chip. This chip will be used in appliances and will be able to control volume signal. This will be a chip that will do the work automatically.
I have read the link but and find the ICs cool. It is a IButton-Sensor type of thing that I want to programme - a sensor for volume. Could someone give me the direction. What and how to code for it? OR you can join me and be my partner in success! We will share the profits, okay!
I want to progress in this endeavour! sob sob!
Thank you for dropping by William Brogden (and others too)!

There's some applications of the ibutton on the website William linked. The compelling use for the ibutton when it was released was personalization. You could carry around your preference data with you (the example at Java One was for your particular mix of coffee). I guess it's just cheaper to treat everyone the same. With the rise of cheap usb flash drives and RFID, I think the ibutton may be extinct. Maki, I think using a java chip for volume control would be overkill. Java makes sense for application programming, not regulating IO. Java chips don't have the same market penetration that other IC's do (PIC, for instance) and are more complex so they will be more expensive (and require more power, generate more heat and so on). Any appliance you could name would probably already have a microcontroller on it. Why the extra chip? How would you integrate it with existing hardware?

Yes you are right Joe Ess. Java not be suitable for some fields, but then what you have siad could be suppositions. why not try to do it practically?
If the whole thing that we create is not so good(have problems the like you mentioned), we can always get hold of some C programmer and convert our code. But it will be a fine practise for us to work on this, what you say?
Right now I have no idea where to begin. By the end of it, we will be more knowledgeable.
I have an idea for a specific industry where volume control has been over looked in reference to requirement. I will create this chip with the help of you guys and pass it to some big name in that industry. It will be upto the company to do the rest. So we share the fruits! I do not want to open the idea to everyone as yet...
Thanx in Advance,
