A challange to all electronic experts (and hobbists)

[myvbox]

Hi everyone,

I'm trying to put up a fairly simple electronic system but i'm don't know how to.
I'm happy to pay for parts and labour .
here we go...

The system components:

* 1 large illuminated red button
* Timer relay
* Red LED countdown timer (2 digits)

Requirements:

1) The button should be connected to a monitor (normal PC 17'' monitor)
and to the countdown timer
2) Each time the button is pushed the timer should countdown 30 seconds, and the monitor will switch on for that period only (30 secs)
3)after 30 seconds the monitor will switch off, (the timer can show 00 or 30 - waiting for the next push (to countdown again)

Thank you for you time

cheers

Ronen
