I
will first make some simple examples with this UI. Then i will try to
interface the javascript with PHP-MYSQL Application. I am just Thinking
Loud. This makes a Globally Distributed Process Control Possible. :~) . You can Use html-js-php-msql. You can use ajax-python-perl too.

But for now, back to earth, I will just complete some more simple
tutorial gadgets. This Idea of mine is Open Source, please keep it that
way.
The advantage is that the industrial process or Home
automation can be monitored and controlled on any computer including
tablets which has a Browser. The plant automation or Home appliance can
be regulated even as you travel back from factory to home. Or in any
city from the Cyber Cafe. A Wireless Lan and Computer with Browser is
all you need.
Press The Power on-off for a soft start, this is
to prevent the inrush current from stressing the javascript components.
Then it goes to a display test. The Start button can run or stop timer
by toggling. The reset will Bring timer to 0000, format is min-sec.
Set
by pressing select to get a marker over orange digit, Use Scroll to set
number. Press Start to start timer, Start to be off to set again. The
buzzer will turn on when Time elapsed matches time set. and the alarm
relay trips. And a Flashing Annunciator signals end of process. Now
Reset will start process again and stop flashing LED.
To use this like a regular instrument, you need a small portable
hand-held computer with browser. Fix that in a Cabinet by filing or
grinding it to size and wire the relays and supply. :-)
