Subject: Electronics Newbie Needs Help With A Timer Delay Circuit...

Hello out there in the world of USENET, this is my first foray into
this public forum so here goes nothing...
I am an average teenage male computer user who builds his machines,
plays games, and stays up till 3 getting 9 extra 3dmarks out of his
radeon...but when it comes to electronics and circuitry, I am lost.
For the fine arts day at my school we can display our art and show it
off to the public that comes to visit and recently the senior art
students have been allowed to produce art instillations for this day.
Long story short, I had an idea for an information podium with a
simple button and a light bulb that would illuminate a transparency
revealing a message. However, to drive home a point of "our" need (the
societal 'our') for instant gratification, I wanted to introduce a
delay into the button circuit.
That is where the problem lies. Great ideas, but not the ability to
execute them. I took a trip to the shack the other day and picked up
General Purpose IC breadboard
TLC555 Timing IC
I realize I will probably need more than this to complete the project
but it was a start. I was planning on using a regular ATX power supply
to supply the circuit with 5V DC and running the light bulb, (or
whatever), off of an AC line.
Like I said before I am not afraid of technology and I have done a
decent amount of soldering work, but I just don't know where to start
what to do. The actually wood construction won't be a problem as my
father is an experienced wood craftsman with tons of tools. He also
has lots of electronics experience but he can't really provide a lot
of help in the way of scratch construction. If anyone out there would
be willing to lend some advice or at least some resources or links it
would be greatly appreciated.
P.S. I also realize that people will probably think the machine is
broke and move on, however I will be putting dummy buttons around the
real one. This way people will randomly press buttons and trip the
delay circuit, but since the reaction isn't immediate, they still
won't know which button did the trick.
