Need to make a prop of sensitive nature

Hi,
As this is my first post I'll introduce myself as that should also help calm any fears as I am going to ask for help making a "bomb" (not a real one, relax)
My name really is Billy (William) and aside from serving in the Army since 1997 I also get involved with corporate training days and running Airsoft events. I have a mechanical background (HND. In automotive engineering) but electronics are absolute witchcraft to me.
In an ideal world I know what I want and what I want it to look like, but in reality I have zero clue how to go about building it.... And I'm pretty sure the Saturday boy in Maplins would have a heart attack if I asked for his assistance!
So yes, I am looking to make a bomb. Controversial and not to everybody's taste but is an excellent tool for making people work under pressure on a timed scenario.
I would like it to have the following options, all of which with their own on/off switch so we can vary the use of the build.
- Loud alarm - loudest health and safety would let us use (120db) if it could be really annoying too that would be great.
- Strobe lights - to operate at the same time as the alarm.
- Alphanumeric key pad - one we can change the code on each time it is used to prevent anybody already knowing it.
- Digital display countdown timer - game scenarios vary but typically they are 1hr in duration. Being able to display 3600 seconds on a count down or 59:59 on a count down would be excellent (alarm and strobes to activate at zero)
Now so far all of that (I think) is relatively straight forward with the right knowledge so this is where I want the moon on a stick.... In addition to the above I would like other methods of either activating the strobes and alarm or disabling the timer or doubling the countdown from 1 second to .5 second intervals.
INSTANT ALARM
- Mercury tilt switch - either as a tamper device in game or as an additional incumberment for corporate days (balance bars and low level assault courses are used. This is a modern take on a tray of wine glasses)
DISABLE OR DOUBLE
- wire cutting - female wire grips bridged by different colour wires. They can be pulled out (or cut for the added atmosphere). The correct cable will disable the device. A wrong cable will double the countdown. (I would need to be able to change which does which as regular players would soon become familiar with whips have wire to pull)
If it is at all possible as well I'd like the keypad to double the timer speed if the wrong code is entered.
I appreciate with all the switching options this may not be particularly straight forward, or even possible. When it comes to the build I am stuck in the dark ages. I could physically put it all together and fabricate it all into a James Bond style case but I wouldn't know where to start with keypads, timers, brains, how to program it all.....
So in short, please help!
Thanks in advance.
