Mike asked constructing a 12v circuit and need help!?

Need to figure out how I can build a 12v circuit similar to a Normally open, timed closed relay. I have been told I need a 555 timer, a transistor (BC107B) and a normal 12v car relay. Been trying to figure this out for a while but got a headache just trying to figure this out. Got some knowledge of electronics but as you might of guessed I'm not to educated so just need help putting things into place. Would be a massive help if someone can show me a schematic of how I can do this. I have an existing third party module that is a black box. It runs on 12v car battery. Pressing a momentary switch causes the module to activate, playing the sound and flashing a number of LEDs in sequence. The problem is that the switch is way too sensitive. You just touch it and the circuit will activate/deactivate. So to prevent accidental activation/deactivation what I want to do is add a delay circuit in front of the module such that you need to press and hold a momentary button for a few seconds before passing along a pulse to activate the black box module. If the button is released before the push and hold time passes no pulse should be passed along. The push and hold time does not to be very accurate, but should be in the range of 5-10 seconds.

And got the following answer:

Check http://en.wikipedia.org/wiki/555_timer#Monostable for a circuit diagram for the first part of the circuit. You need to choose a value for "R" and "C" to determine how long the relay is on for. The equation for the on-time is: t = 1.1 * ( R / C ) e.g. If you use a 1microFarad capacitor and a 10kOhm resister, it will be on for 1.1 seconds. The 555 is triggered by connecting pin 2 to ground - this starts the 'on' state. However, the time delay itself doesn't actually start until pin 2 is disconnected from ground again. You might find unpredictable results in your car due to a varying 12V supply, in which case you can permanently connect pin 2 to 12V with a 10k resistor to prevent spurious resets - you'll still need to short pin 2 to ground to trigger the timer. Connect pin 3 to the Base of the transistor. Connect the relay between 12V and the Emitter and connect the Collector to ground. Make sure you also connect a diode *in reverse* across the relay coil to prevent the lethal (lethal to the transistor) voltage produced across the coil when the relay is turned off. I can get you a full schematic later if you need it; email me if you do. EDIT: See http://imageshack.us/photo/my-images/29/555mono.jpg/ . .for a schematic; it's fairly simple. EDIT 2: If you want to stop the false-triggering problem you mention in your updated question, you need a Schmitt Trigger, or some other form of debouncing circuit. Also, the hard bit, you need to know where the 'momentary push switch' is in the circuit - does this switch trigger the module by supplying a voltage to an input or by removing a voltage (grounding, like the 555 trigger) the input. You could no doubt use the schematic I have included to do the trick - simply wire up the relay contacts (the 'output' side) in direct replacement for the switch on the black box. With this setup the black box will activate every time you press the button on the 555, irrelevant of how long you press it for. However, the useful bit is that subsequent presses are ignored for a given time period: Module off. *Press button* Module on. Wait 1 second. *press button* nothing happens wait 1 second *press button* nothing happens etc. wait 1.1*R*C seconds *press button* Module turns off. Make any sense?
